Use of polyimide foam stabilizer in high-speed train compartments: Provides a quiet and comfortable travel environment

2月 21st, 2025 News

Chaos and needs of environment in high-speed trains

With the rapid development of modern transportation technology, high-speed trains have become an important choice for people’s daily travel. However, while enjoying the convenience of speed, we also face a series of unique challenges. During high-speed operation, noise and vibration problems in train cars are particularly prominent. These factors not only affect passenger comfort, but may also pose health risks to staff who have been riding for a long time.

First, the aerodynamic noise generated when high-speed trains are running is a major problem. When the train is traveling at a speed of more than 300 km/h, the friction between the body and the air produces significant wind noise. This noise is transmitted into the interior of the car through windows, doors and other parts, forming continuous background noise. In addition, mechanical vibration caused by wheel and rail contact will also be transmitted to passengers through the floor and seats, further aggravating the discomfort.

Secondly, temperature control in the car is also an important consideration. Due to the fast speed of the train, the temperature outside changes dramatically, and the large number of people in the car, how to maintain a constant and comfortable temperature has become a major challenge. Although traditional air conditioning systems can adjust the temperature, their effect is often greatly reduced when opening and closing doors at high frequency, and they also increase additional energy consumption.

To address these challenges, scientists have begun to explore the application of new materials, in which polyimide foam stabilizers have attracted much attention for their outstanding performance. This type of material not only has excellent sound insulation and noise reduction capabilities, but also effectively insulates and insulates heat, thus providing a quieter and more comfortable travel environment for high-speed trains. Next, we will explore in-depth the working principle of polyimide foam stabilizers and their performance in practical applications.

Basic Characteristics and Functions of Polyimide Foam Stabilizer

Polyimide foam stabilizer is a high-tech material that stands out in the industrial field for its outstanding physical and chemical properties. Its core component, polyimide, is a high-performance polymer with extremely high heat resistance and mechanical strength, which makes it stable under extreme conditions. Specifically, the main characteristics of polyimide foam stabilizers include excellent thermal stability, good chemical resistance, and excellent electrical insulation properties.

Structurally, polyimide foam stabilizers are formed through complex molecular cross-linking networks, which give it extraordinary lightness and flexibility. This means that even under high pressure or high temperatures, the material can maintain its morphology while maintaining a low density, which is crucial to reducing the overall weight of high-speed trains. In addition, polyimide foam stabilizer also exhibits excellent acoustic performance, which can effectively absorb and block sound transmission, providing passengers with a quieter ride experience.

In practical applications, the function of polyimide foam stabilizers is much more than this. For example, it can meet different usage needs by adjusting the formula. For situations where higher fire protection levels are required, specialThe porosity of the foam can be increased in places where stronger sound insulation is required. This flexibility makes polyimide foam stabilizers ideal for a variety of applications, especially in complex environments such as high-speed trains.

In short, polyimide foam stabilizer, with its unique physical and chemical properties, provides a comprehensive solution for high-speed trains, not only significantly reducing noise and vibration, but also effectively controlling the temperature in the car and ensuring passengers. Enjoy a higher quality travel experience. The following will introduce its specific applications in sound insulation and noise reduction and thermal insulation.

The application and advantages of polyimide foam stabilizer in sound insulation and noise reduction

Sound insulation and noise reduction are a crucial task in the design of high-speed trains, as it directly affects passenger comfort and travel experience. As an innovative material, polyimide foam stabilizer demonstrates unique advantages in this field with its outstanding acoustic properties and versatility.

1. Sound absorption and sound insulation mechanism

One of the core functions of polyimide foam stabilizers is its efficient sound absorption ability. This material captures and absorbs sound wave energy through its internal porous structure, converting it into thermal energy, thereby significantly reducing the reflection and propagation of sound. Specifically, when sound waves enter the inside of the foam, they will be dispersed by countless tiny bubbles, which are like small energy traps, preventing the linear propagation of sound waves. This mechanism is not only suitable for low-frequency noise, but also has a good suppression effect on high-frequency noise.

In addition, polyimide foam stabilizer also has excellent sound insulation properties. By applying a dense protective layer to its surface, it can effectively block the intrusion of external noise. This dual effect—both sound absorption and sound insulation—makes polyimide foam stabilizers ideal for noise reduction in high-speed train compartments.

2. Comparison with traditional materials

To better understand the advantages of polyimide foam stabilizers, we can compare them with traditional sound insulation materials. The following is a comparison of key parameters of several common sound insulation materials:

Material Type Density (kg/m³) Acoustic Performance (NRC) Heat resistance (°C) Service life (years)
Polyimide Foam Stabilizer 15-40 0.8-1.0 >300 >20
Fiberglass Fiberglass Cotton 16-32 0.7-0.9 <200 10-15
Polyurethane foam 20-50 0.6-0.8 <100 8-12

As can be seen from the table above, although fiberglass cotton and polyurethane foams also perform well in some aspects, their limitations in heat resistance and service life make it difficult to compete with high-demand environments such as high-speed trains. . In contrast, polyimide foam stabilizers not only perform excellent in acoustic performance, but also have higher heat resistance and longer service life, making it a more reliable option.

3. Actual case analysis

In practical applications, the effect of polyimide foam stabilizer has been fully verified. For example, in a high-speed train renovation project, the engineer team applied polyimide foam stabilizer to the sound insulation layer of the carriage floor and side walls. The test results showed that the noise level in the carriage was reduced by about 15 decibels, which was equivalent to reducing nearly half of the subjective perceived noise. In addition, due to the lightweight nature of the material, the weight of the entire train did not increase significantly, but instead decreased slightly due to the overall design optimization.

In addition, the installation process of polyimide foam stabilizer is relatively simple. Due to its flexibility and easy cutting characteristics, construction workers can quickly adjust the shape of materials according to specific needs, greatly improving construction efficiency. Moreover, once installed, it is extremely costly to maintain and requires little additional maintenance.

To sum up, polyimide foam stabilizer provides a perfect solution for sound insulation and noise reduction in high-speed trains with its excellent sound absorption and sound insulation performance, combined with its advantages of lightweight, high temperature resistance and long life. . Next, we will explore the application of this material in thermal insulation and its unique advantages.

The application and advantages of polyimide foam stabilizer in thermal insulation

During the operation of high-speed trains, changes in temperature differences inside and outside the car often cause passengers to feel uncomfortable. Especially in cold winters or hot summers, temperature control in the carriage is particularly important. Polyimide foam stabilizers have become the ideal material to solve this problem with their excellent thermal insulation properties.

1. Thermal insulation mechanism and performance

The reason why polyimide foam stabilizers can perform well in thermal insulation is mainly due to their unique microstructure. The material consists of a large number of evenly distributed micropores, which are filled with stationary air, which itself is an excellent insulating medium. These micropores act as a hindering effect when heat is attempted to pass through the material, significantly slowing down the rate of heat conduction. In addition, the polymer chain structure of the polyimide itself also has an extremely low thermal conductivity, which further enhances its thermal insulation performance.

Specifically, the thermal conductivity of polyimide foam stabilizers is usually below 0.02 W/(m·K), which is much lower than most traditional insulation materials such as polyethylene foam or rock wool. The low thermal conductivity means that the material can more effectively prevent the transfer of heat, thereby maintaining the stability of the temperature in the car.

2. Comparison with other thermal insulation materials

To understand the advantages of polyimide foam stabilizers more intuitively, we can compare them with other common thermal insulation materials through the following table:

Material Type Thermal conductivity (W/(m·K)) Fire Resistance (°C) Service life (years) Maintenance Requirements
Polyimide Foam Stabilizer <0.02 >300 >20 Extremely low
Polyethylene Foam 0.03-0.04 <100 8-12 Medium
Rockwool 0.035-0.045 <600 15-20 Higher

As can be seen from the table, although polyethylene foam and rock wool can also provide better insulation in some cases, their shortcomings in fire resistance and service life limit their inability to high-speed trains Application. Polyimide foam stabilizer shows obvious advantages in these two key indicators, ensuring its stability and safety during long-term use.

3. Practical application cases

In practical applications, polyimide foam stabilizers have been widely used in thermal insulation design of high-speed trains. For example, during the research and development of a new high-speed rail project, engineers decided to use polyimide foam stabilizer as the thermal insulation layer on the top and side walls of the car. After multiple tests, the results showed that the temperature fluctuation range in the car was significantly reduced, especially in extreme weather conditions, the interior of the car could still maintain a comfortable temperature. In addition, due to the lightweight nature of the material, the overall weight of the train did not increase significantly due to the addition of the thermal insulation layer, but was reduced by the optimized design of other components.

It is worth mentioning that the installation and maintenance of polyimide foam stabilizer is also very convenient. Due to its flexibility and ease of workability, construction workers can easily rootCutting and splicing according to the specific size of the carriage has greatly shortened the construction time. At the same time, because the material itself has strong weather resistance and anti-aging capabilities, its subsequent maintenance needs are extremely low, and almost no additional maintenance work is required.

IV. Summary of comprehensive advantages

The application of polyimide foam stabilizer in the field of thermal insulation not only solves the problem of temperature difference between inside and outside the high-speed train compartment, but also takes into account the characteristics of the material’s lightweight, fire resistance and long life.

Polyimide foam stabilizer: Super Warriors who resist extreme temperatures

The reason why polyimide foam stabilizers can maintain high-efficiency performance in extreme climates is mainly due to their unique molecular structure and physical properties. This material consists of aromatic polyimide chains that form an extremely stable three-dimensional structure through a complex crosslinking network. This structure imparts excellent thermal stability to the polyimide foam, maintaining its shape and function even in high or low temperature environments.

Specifically, the thermal conductivity of polyimide foam is very low, usually between 0.02 and 0.04 W/m·K, which means it can effectively prevent the conduction of heat, whether it is transmitted from the external environment or From the inside. This makes it an ideal insulation material, especially suitable for building environments where strict indoor temperature control is required.

In addition to excellent thermal insulation properties, polyimide foam also has excellent mechanical strength and durability. Its tensile strength can reach 5 to 10 MPa and its compressive strength is about 2 to 8 MPa, which shows that it can not only withstand a certain amount of external pressure, but also keep its performance unchanged during long-term use. This strength and durability are particularly important in protecting building exterior walls from climate change.

In addition, polyimide foams also exhibit good tolerance to a variety of chemicals, including acids, alkalis and other corrosive substances. This chemical stability not only extends the service life of the material, but also reduces maintenance costs and improves economic benefits.

To sum up, polyimide foam stabilizers rely on their unique molecular structure and physicsIts characteristics, which can effectively resist extreme temperature changes, provide lasting thermal insulation and structural support, are ideal for modern building exterior wall insulation.
