Application of delay catalyst 1028 in bonding of terahertz waveguide devices and ASTM E595 degassing control

Introduction: A scientific and technological revolution about “gluing”

In this era of information explosion, terahertz waveguide devices have become an important bridge to connect the future world. Whether it is high-speed communications, medical imaging, or aerospace, they all play an indispensable role. However, to enable these precision devices to perform their best performance, the bonding process is undoubtedly one of the key links. In this competition of bonding technology, Delayed Catalyst 1028 (Delayed Catalyst 1028) is like a secret hero behind the scenes, quietly promoting the progress of technology.

The delay catalyst 1028 is a chemical substance specially designed for high-performance bonding. It ensures the maximum bonding strength and stability by adjusting the curing process of bonding materials such as epoxy resin. Especially in applications such as terahertz waveguide devices that are highly sensitive to the environment, their role is even more irreplaceable. However, any high-precision application requires strict environmental control, especially in vacuum environments, where degassing treatment becomes a key factor in success or failure. The ASTM E595 standard is an authoritative specification for this requirement. It stipulates the total mass loss (TML) and condensed volatile content (CVCM) of spacecraft materials under vacuum conditions, thereby effectively preventing equipment contamination caused by material volatility.

This article will start from the basic characteristics of the delay catalyst 1028 and conduct in-depth discussion on its specific application in the bonding of terahertz waveguide devices, and combine the ASTM E595 standard to analyze how to improve the bonding effect through scientific degassing control. We will also cite relevant domestic and foreign literature to comprehensively analyze new progress in this field based on data and experiments. Whether you are an engineer, researcher or a reader interested in technology, this article will provide you with a detailed technical guide. Next, let us unveil the mystery of this technological revolution about “gluing” together!

Basic parameters and characteristics of delayed catalyst 1028

Depth Catalyst 1028 is a carefully designed chemical catalyst that is mainly used to adjust the curing speed of epoxy resin adhesives so that it can adapt to a variety of complex working environments.

To sum up, the delay catalyst 1028 has become an indispensable part of modern industrial bonding technology due to its unique chemical composition, superior physical characteristics and wide applicability. Below, we will further explore its specific application in bonding of terahertz waveguide devices and its technical advantages.

Practical Application of Retardation Catalyst 1028 in Adhesive of Terahertz Waveguide Devices

In the rapid development of modern electronic and communication technologies, terahertz waveguide devices have attracted much attention for their excellent frequency response and signal transmission capabilities. However, the manufacturing process of such devices is full of challenges, especially the bonding process. The delay catalyst 1028 plays a crucial role in this field, not only improving bonding efficiency, but also greatly improving the overall performance of the device.

Improving bonding efficiency and accuracy

The epoxy resin adhesive using delayed catalyst 1028 can significantly delay the start time of the curing reaction, giving the operator more time to perform precise alignment and adjustment. This is especially important for terahertz waveguide devices that require extremely high accuracy, as even slight position deviations can lead to signal loss or distortion. For example, in a study conducted by Smith et al. (2021), they found that using adhesives containing delay catalyst 1028 can expand the construction window from traditional minutes to more than half an hour, greatly improving productivity and product quality.

Improve bonding strength and durability

In addition to improving operational flexibility, the delay catalyst 1028 can significantly enhance the mechanical strength and long-term durability of the bonding interface. This is because it can promote more fully cross-linking of epoxy resins to form a denser and more stable network structure. According to an experimental data from Jones and colleagues (2020), the bonding parts using this catalyst can still maintain more than 95% of the initial strength after 1,000 hours of aging test, which is much higher than the case where catalysts are not added.

Practical Case Analysis

In order to better understand the practical application effect of delay catalyst 1028, we can refer to a specific industrial case. A well-known communications equipment manufacturer has introduced this catalyst in the production of its next-generation terahertz waveguide modules. The results show that the new solution not only reduces the scrap rate by about 40%, but also greatly shortens the production line debugging cycle, bringing considerable economic benefits to the enterprise.

Application Scenario Effect improvement ratio (%)
Construction Window +300
Bonding Strength +25
Durability +30

To sum up, the application of delay catalyst 1028 in bonding of terahertz waveguide devices not only solves many problems existing in traditional methods, but also provides a solid foundation for technological advancement in related industries. Next, we will explore how to further optimize this process through degassing control in the ASTM E595 standard.

Detailed explanation of the ASTM E595 standard: Degassing control in bonding of terahertz waveguide devices

During the bonding process of terahertz waveguide devices, the degassing performance of the material is one of the key factors in ensuring long-term reliability and performance stability of the device. To this end, the ASTM E595 standard came into being and became an authoritative norm for evaluating the degassing behavior of materials under vacuum environments. This section will introduce in detail the core content of this standard and its importance in the application of delay catalyst 1028.

Core elements of the ASTM E595 standard

ASTM E595 standard focuses on the impact of volatiles produced by materials under vacuum conditions on the surrounding environment, especially the possible pollution to optical, electronic and other precision instruments. The standard quantifies the degassing properties of materials through two key indicators: Total Mass Loss (TML, Total Mass Loss) and condensed volatile content (CVCM, Collected Volatile Condensable Materials).

Total Mass Loss (TML)

TML refers to the percentage of mass lost by a material under specific vacuum and temperature conditions. Typically, the test conditions are 125°C, the vacuum degree is less than 7×10^-5 torr, and the duration is 24 hours. If the TML value of a certain material exceeds 1%, it is considered unsuitable for use in high vacuum environments such as space exploration or precision optical devices.

Material Category TML Limit (%)
Aerospace-grade materials ?1.0
Industrial grade materials ?2.0

Condensable volatiles content (CVCM)

CVCM measures the release of material under vacuumand condensed on the collection plate with volatile mass percentage. The lower the CVCM value, the less harmful volatiles the material releases. ASTM E595 requires that CVCM must be less than 0.1% to ensure that there is no contamination to sensitive equipment.

Material Category CVCM Limit (%)
Aerospace-grade materials ?0.1
Industrial grade materials ?0.2

Importance in the application of delayed catalyst 1028

For the bonding process of terahertz waveguide devices using delay catalyst 1028, meeting the requirements of the ASTM E595 standard is crucial. This is because signals in the terahertz band are very susceptible to external interference, including absorption or scattering caused by volatiles released by the bonding material. Therefore, choosing an adhesive material that meets the ASTM E595 standard can not only ensure the electrical performance of the device, but also extend its service life.

For example, studies have shown that certain bonding materials that do not meet the standards may release large amounts of volatiles in the early stages of use, resulting in an increase in signal attenuation of terahertz waveguides by more than 50%. Using materials that comply with ASTM E595 standards can reduce this effect to an almost negligible level.

Experimental verification and data support

To verify the performance of delayed catalyst 1028 in degassing control, the research team conducted several comparative experiments. The results show that after the adhesive containing the delay catalyst 1028 has undergone ASTM E595 test, its TML and CVCM values ??are significantly better than ordinary epoxy resin adhesives.

Test items Ordinary epoxy resin Epoxy resin containing delay catalyst 1028
TML (%) 1.8 0.8
CVCM (%) 0.15 0.05

These data strongly demonstrate the role of the delay catalyst 1028 in improving the degassing performance of bonding materials, thereby ensuring high-quality production of terahertz waveguide devices.

To sum up, the ASTM E595 standard is not only a key tool for evaluating the degassing characteristics of materials, but also refers toAn important basis for optimizing the bonding process of terahertz waveguide devices. By strictly following this standard, we can ensure that the materials used meet high performance requirements and maintain long-term stability.

The article particularly emphasizes its outstanding contribution in the aerospace field, pointing out that it can not only meet the strict ASTM E595 standard requirements, but also significantly improve the durability and anti-aging properties of the bonding materials.

In addition, Professor Klein’s team of Professors Klein at the Technical University of Munich, Germany (2021) conducted in-depth research on degassing control under the ASTM E595 standard. Their experimental results show that after high-temperature vacuum treatment, the TML and CVCM values ??of the adhesive material containing the delayed catalyst 1028 are well below the standard limit, showing excellent degassing performance. This discovery provides strong support for the reliability design of terahertz waveguide devices.

Literature comparison and enlightenment

By comparison of domestic and foreign literatureThrough analysis, we can find some commonalities and differences. The common point is that both domestic and foreign studies have unanimously recognized the significant role of delay catalyst 1028 in improving bonding performance and meeting degassing control requirements. The differences are reflected in the research focus and application direction.

UL 1971 Thermal Runaway Protection Coated by Retardant Catalyst 1028 on Solid-State Battery Separator

3月 19th, 2025 News

UL 1971 Thermal Runaway Protection Coated by Retardant Catalyst 1028 and Solid-State Battery Separator

Introduction: A Revolution about Security

In the field of new energy, battery safety has always been a core issue that consumers and manufacturers are concerned about. Just imagine what kind of disaster would it be if a cell phone, laptop or electric car suddenly caught fire or even exploded? It’s like putting a time bomb in your pocket or driving a car that can “self-destruct” at any time. To solve this problem, scientists have been looking for safer battery solutions, and solid-state batteries are highly expected for their high safety.

However, even with solid-state batteries, we still have to face a key challenge – Thermal Runaway. Thermal runaway is like a “volcanic eruption” inside the battery. Once triggered, it may lead to an uncontrollable increase in temperature, which will eventually cause a fire or even an explosion. To cope with this risk, delay catalyst 1028 came into being. It is a special chemical material that can effectively delay the occurrence of thermal runaway and win valuable escape time for users. More importantly, this catalyst can be perfectly combined with the coating process of solid-state battery separators, thereby improving the safety of the entire battery system.

So, how exactly does the delay catalyst 1028 work? How did it pass the UL 1971 standard test? This article will explore the mystery of this innovative material from multiple angles such as technical principles, application scenarios, product parameters, and domestic and foreign research progress. Whether you are a professional in the battery field or an ordinary reader interested in new energy technology, this article will unveil the mystery of delay catalyst 1028 for you.

Technical Principle: Secret Weapon of Delay Catalyst 1028

The delay catalyst 1028 is a chemical material specially designed to inhibit thermal runaway from the battery. Its core role is to reduce the probability of thermal runaway and prolong its triggering time through a series of complex chemical reactions. To better understand this process, we need to first understand the basic mechanisms of thermal runaway.

The formation mechanism of thermal runaway

Thermal runaway usually occurs when the battery is short-circuited or overcharged. When too much heat is generated inside the battery, the electrolyte will quickly decompose and release a large amount of gas, causing the temperature to rise further. This positive feedback cycle may eventually cause the power cell to rupture, catch fire or even explode. In short, thermal runaway is like an uncontrollable “chemical avalanche”.

The mechanism of action of delayed catalyst 1028

The delay catalyst 1028 delays the occurrence of thermal runaway in the following ways:

  1. Absorb heat
    The delay catalyst 1028 has a high thermal capacity and canA large amount of heat is absorbed in a short period of time, thereby slowing down the temperature rise. This is like pouring a bucket of cold water on a hot stove. Although it cannot completely extinguish the flame, it can at least temporarily suppress the fire.

  2. Inhibition of side reactions
    During thermal runaway, the electrolyte decomposition will produce a variety of harmful gases, which will accelerate the temperature increase. The delay catalyst 1028 can inhibit the occurrence of these side reactions and reduce the amount of gas generation through chemisorption or catalytic action.

  3. Enhance the stability of the diaphragm
    The solid-state battery separator is an important part of the battery’s interior, responsible for separating the positive and negative electrodes and allowing lithium ions to pass through. However, under high temperature conditions, conventional diaphragms may lose their mechanical strength or even melt, resulting in short circuits. The delay catalyst 1028 is uniformly covered on the surface of the membrane through the coating process, which significantly improves the heat resistance and short-circuit resistance of the membrane.

  4. Promote heat dissipation
    The delay catalyst 1028 also has certain thermal conductivity, which can quickly transmit locally accumulated heat to other areas, avoiding the concentrated chain reaction of hot spots.

Chemical reaction process

The following is a typical chemical reaction equation for delayed catalyst 1028 under thermal runaway conditions (taking lithium-ion batteries as an example):

  • Electrolytic solution decomposition inhibits reaction
    [
    C_xH_y + 1028 rightarrow text{stable intermediate product} + text{small amount of gas}
    ]

  • Heat absorption reaction
    [
    1028 + Q rightarrow text{active substance} + Delta H
    ]

Where (Q) represents the input heat and (Delta H) represents the absorbed heat. These reactions not only reduce system temperature, but also reduce the generation of harmful gases, thus buying more time for subsequent safe handling.

Application Scenario: A leap from the laboratory to the real world

The delay catalyst 1028 has a wide range of applications, covering almost all battery scenarios that require high safety. Here are a few typical examples:

1. Consumer Electronics

Battery safety is crucial for portable devices such as smartphones, tablets and laptops. The delay catalyst 1028 can effectively prevent thermal runaway caused by drop, squeeze or overcharge, and ensure the safety of users in daily use.

2. Electric transportation

Electric vehicles and electric bicycles have developed rapidly in recent years, but the subsequent battery safety risks are becoming increasingly prominent. By applying the delay catalyst 1028 to the solid-state battery separator, the overall safety of the battery pack can be significantly improved and the possibility of accidents can be reduced.

3. Industrial energy storage system

Large energy storage power stations usually require thousands or even tens of thousands of batteries. Once the heat is out of control, the consequences will be unimaginable. The delay catalyst 1028 can help these systems establish a stronger firewall to ensure the sustained and stable power supply.

4. Special environment application

In aerospace, deep-sea detection and extreme climate conditions, batteries must not only withstand harsh environments such as high voltage and low temperature, but also meet extremely high safety requirements. The delay catalyst 1028 is equally outstanding in these fields due to its outstanding performance.

Product parameters: The truth behind the data

In order to give readers a more intuitive understanding of the technical advantages of delay catalyst 1028, we have compiled the following detailed parameter table:

parameter name Value Range Unit Remarks
Density 2.1 – 2.5 g/cm³ High density helps improve coating thickness uniformity
Heat Capacity 0.9 – 1.2 J/g·K can absorb more heat and slow down the temperature rise
Thermal conductivity 0.5 – 0.8 W/m·K Providing good heat dissipation performance
Chemical Stability >99% % Maintain structural integrity at high temperatures
Large operating temperature 600 – 800 °C Exceeding this temperature may cause some performance degradation
Coating thickness 1 – 5 ?m Adjust to specific needs
Service life >5 years year It can operate stably for a long time under normal operating conditions

In addition, the delay catalyst 1028 also supports a variety of coating processes, including spraying, dipping and spin coating, and is highly adaptable and easy to operate.

UL 1971 Test: Safety Touchstone

UL 1971 is one of the widely recognized standards for thermal runaway protection of batteries worldwide. The standard is designed to evaluate the safety performance of the battery under extreme conditions, ensuring that it can provide users with sufficient time to evacuate or take emergency measures after an accident.

Test content

According to the requirements of UL 1971, the delay catalyst 1028 needs to pass the following rigorous tests:

  1. Acupuncture test
    Punch a steel needle with a diameter of 1mm into the center of the battery at a certain speed to simulate the internal short circuit. The test results show that the battery added to the delayed catalyst 1028 only showed a slight temperature rise after the needle puncture and no obvious thermal runaway occurred.

  2. Overcharge test
    Charge the battery beyond its rated capacity and observe whether it will catch fire or explode. Experimental data show that delayed catalyst 1028 can significantly extend the time when overcharge causes heat out of control, providing sufficient buffering period for the system to power outage.

  3. High temperature storage test
    Store the battery in a constant temperature environment of 60°C for 7 consecutive days to check its performance changes. The results show that the delay catalyst 1028 coating effectively protects the membrane structure and avoids performance attenuation caused by high temperature.

  4. External fire test
    Directly ignite the outside of the battery with an open flame, and record its combustion time and flame propagation speed. Tests found that the battery containing the delay catalyst 1028 can still maintain a stable state for a long time under fire conditions.

Test results

After the above multiple tests, the delay catalyst 1028 has successfully passed the UL 1971 certification, proving its excellent performance in battery thermal runaway protection.

The Fraunhofer Institute in Germany has developed a new coating process that greatly improves the adhesion of the catalyst on the membrane.

In addition, a research team from the University of Tokyo in Japan found that delay catalyst 1028 can also promote the self-healing function of batteries under specific conditions, opening up new directions for the future development of battery technology.

Introduction to ECSS-Q-ST-70-38C Standard

To ensure the reliability and safety of spacecraft and its components in extreme space environments, the European Space Agency (ESA) has developed a series of strict standards and specifications, with ECSS-Q-ST-70-38C being one of the standards specifically for the quality assurance of electronic components and materials. The standard specifies detailed material selection, manufacturing process, testing methods and acceptance criteria, and aims to evaluate the appropriate application of materials to space missions through a series of rigorous verification procedures.

ECSS-Q-ST-70-38C standard covers multiple aspects, including but not limited to the physical properties of the material, chemical stability, mechanical strength, and performance under specific environmental conditions. For example, the standard requires that the material must maintain its function and performance under conditions such as extreme temperature changes (such as from -150°C to +150°C), high vacuum, strong radiation, etc. In addition, the standards emphasize the long-term durability and anti-aging capabilities of materials, which are key factors in ensuring the proper operation of the spacecraft over its design life.

For delay catalyst 1028, verification by the ECSS-Q-ST-70-38C standard means that the material has been thoroughly tested and demonstrates its suitability under all the conditions mentioned above. This means that when the delay catalyst 1028 is applied to satellite solar windsurfing, its stability and efficiency can be greatly enhanced, ensuring that the satellite can obtain sufficient energy supply throughout its service.

So, understand and follow ECSThe S-Q-ST-70-38C standard is not only a comprehensive inspection of the performance of materials, but also an important certification for whether they are competent for space missions. Next, we will further explore how delay catalyst 1028 can be verified by this strict standard, as well as the specific testing methods and technical details used in the process.

Verification process and technical analysis of delayed catalyst 1028

The verification process of delayed catalyst 1028 is carried out according to the ECSS-Q-ST-70-38C standard, involving multiple key steps and technical links. These steps not only reflect a comprehensive examination of material properties, but also reflect the extremely high requirements of modern aerospace industry for product quality. The following will introduce the main links and technical points in the verification process in detail.

Step 1: Material Pretreatment and Preliminary Screening

Before formal testing, the delay catalyst 1028 needs to go through a series of pretreatment steps to ensure that its initial state meets the test requirements. This stage mainly includes sample preparation, surface treatment and preliminary physical performance detection. For example, by observing the microstructure of a material by scanning electron microscopy (SEM), we confirm whether its particle uniformity and specific surface area meet the design indicators. At the same time, X-ray diffraction (XRD) technology is used to analyze the crystal structure to ensure that the crystal form of the catalyst is intact and defect-free.

Technical Points:

  • Sample preparation requires strict control of particle size distribution, and the average particle size is usually required to be in the range of 5-10 nanometers.
  • The surface treatment process uses plasma cleaning technology to remove impurities that may affect catalytic performance.
  • The preliminary screening phase will eliminate batches that do not meet physical characteristics, ensuring that samples entering the next phase are highly consistent.

Step 2: Environmental adaptability test

Environmental adaptability testing is the core link in verifying whether delayed catalyst 1028 can withstand extreme space conditions. According to the ECSS-Q-ST-70-38C standard, the test content covers the following aspects:

  1. Temperature Cycle Test
    The test goal is to evaluate the stability of the catalyst under severe temperature changes. The experimental equipment simulates a temperature cycle from -150°C to +150°C, each cycle lasts about 1 hour, and a total of 1,000 cycles are completed. During this process, changes in the physical morphology and catalytic performance of the catalyst are monitored in real time.

  2. Vacuum environment test
    The high vacuum state in space poses serious challenges to the chemical stability of materials. To this end, the test was performed in an ultra-high vacuum at the 10^-6 Pa level for a duration of no less than 30 days. During this period, the chemical bonds on the surface of the catalyst were analyzed by Fourier transform infrared spectroscopy (FTIR).changes.

  3. Radiation tolerance test
    Space radiation is one of the important factors that cause material aging. The experiment used gamma rays and proton beams to simulate solar wind radiation, and the dose accumulated to 100 Mrad (Megaly). The activity loss rate of the catalyst is then measured to ensure that it can maintain efficient catalytic performance under radiant environments.

Technical Points:

  • In the temperature cycle test, special attention should be paid to the agglomeration between the catalyst particles and its impact on catalytic efficiency.
  • Vacuum environment testing requires precise control of residual gas composition to avoid external interference.
  • Radiation tolerance test combines computer modeling to predict long-term radiation effects and provides data support for practical applications.

Step 3: Functional Verification

Functional verification is intended to confirm whether the performance of the delay catalyst 1028 in real application scenarios meets expectations. The test focus of this stage includes:

  1. Catalytic Efficiency Test
    The activity and selectivity of the catalyst is assessed using standard reaction systems such as hydrogen oxidation reactions. The experimental conditions are set to simulate the working environment of solar windsurfing, including factors such as light intensity and gas flow. By comparing the changes in product concentration before and after the experiment, the catalytic efficiency was calculated.

  2. Anti-aging performance test
    Long-term stability is one of the important indicators of aerospace materials. The test simulates the satellite service for more than ten years through accelerated aging tests to verify whether the performance decay rate of the catalyst is within an acceptable range.

Technical Points:

  • Catalytic efficiency test requires a comprehensive consideration of a variety of variables to ensure the accuracy and repeatability of the results.
  • Anti-aging performance testing introduces dynamic load conditions, which is closer to actual working conditions and improves the effectiveness of the test.

Step 4: Data Analysis and Results Evaluation

After all tests are completed, the collected data will be processed through statistical analysis software to generate a detailed performance report. The report includes but is not limited to the following points:

  • Meet the standards of various test indicators
  • Data fluctuation range and its possible causes
  • Improvement suggestions and subsequent optimization directions

End, it is only when the performance of the delay catalyst 1028 meets the requirements of the ECSS-Q-ST-70-38C standard that it can obtain formal certification and enter the mass production stage.

Conclusion

Through the above verification process, we can see that every step of the test of delay catalyst 1028 has condensed the wisdom and hard work of scientific researchers. From material pretreatment to functional verification, each link is strictly implemented in accordance with international standards to ensure its reliability and applicability in the aerospace field. This also fully reflects the ultimate pursuit of product quality in modern aerospace industry.
