- Environmental Safety: The material is non-toxic and odorless, and is degradable, in line with modern environmental protection concepts.
- High economicality: Although the initial investment is high, its long service life and low maintenance cost make it have significant economic benefits in long-term use.
2. Application scenarios of polyurethane sponge aldehyde removal agent in public facilities maintenance
2.1 Subway stations and bus hubs
Subway stations and bus hubs are important components of urban transportation. They have large flow of people and poor air circulation, which are prone to accumulation of harmful gases. Polyurethane sponge aldehyde removal agent can be used in the following aspects:
- Wall and ceiling decoration: Embed aldehyde remover into the decorative material to continuously purify the air.
- Seat and Armaries: Use aldehyde removers in the filling materials of seats and armrests to improve passenger comfort.
- Ventiation System: Install aldehyde removal agent module in the ventilation duct to improve air quality.
2.2 Hospitals and schools
Hospitals and schools are places with high air quality requirements in public facilities. The application of polyurethane sponge aldehyde removal agent can effectively reduce formaldehyde concentration and reduce the occurrence of respiratory diseases.
- Ward and classroom walls: Use wall materials containing aldehyde removal agents to continuously purify the air.
- Furniture Filling: Use aldehyde removal agents in beds, desks and other furniture to improve the safety of use.
- Air Purification Equipment: Integrate aldehyde removal agent into the air purifier to enhance the purification effect.
2.3 Library and Museum
As cultural places, libraries and museums have extremely high requirements for environmental cleanliness and stability. Polyurethane sponge aldehyde removal agent can be used for:
- Bookshelf and Showcase: Use aldehyde removers in the filling materials of bookshelf and showcase to protect books and cultural relics.
- Floor Materials: Add aldehyde removal agent to the ground materials to reduce ground pollution.
- Air conditioning system: Install aldehyde removal agent module in the air conditioning system to ensure fresh air.
III. Polyurethane sponge aldehyde removal agent pairEffects of maintenance frequency
3.1 Reduce repairs caused by material aging
Traditional public facility materials are prone to frequent repairs due to aging and corrosion during long-term use. Polyurethane sponge aldehyde removal agent has excellent durability and anti-aging properties, which can significantly extend the service life of the facility. For example, after using aldehyde remover in wall decoration of subway stations, the phenomenon of cracking and falling off of walls has been reduced by more than 60%.
3.2 Reduce maintenance needs caused by air quality problems
Poor air quality can lead to deterioration of the internal environment of the facility, which in turn causes equipment failure or material damage. Polyurethane sponge aldehyde removal agent reduces maintenance needs due to air quality problems by continuously purifying the air. For example, after using aldehyde removers in hospitals, the failure rate of the air conditioning system was reduced by 40%.
3.3 Data support
The following table shows the comparison of the frequency of repair before and after the use of polyurethane sponge aldehyde remover in a city in subway stations, hospitals and schools:
| Type of place | Average number of repairs before use | Average annual maintenance times after use | Repair frequency reduction ratio |
|---|---|---|---|
| Subway Station | 12 times | 5 times | 58.3% |
| Hospital | 8 times | 3 times | 62.5% |
| School | 6 times | 2 times | 66.7% |
It can be seen from the table that the use of polyurethane sponge aldehyde removal agents significantly reduces the frequency of maintenance of public facilities.
IV. Improvement of service quality by polyurethane sponge aldehyde removal agent
4.1 Improve user experience
The service quality of public facilities is directly related to user satisfaction. Polyurethane sponge aldehyde removal agent provides users with a more comfortable and safe environment by improving air quality and extending the service life of the facility. For example, after using aldehyde removers in subway stations, passenger satisfaction increased by 20%.
4.2 Improve the image of the facility
The exterior and internal environment of the facility are an important part of the urban image. The use of polyurethane sponge aldehyde removal agent makes the facilities more neat and beautiful, and enhances the overall image of the city. For example, after a museum used aldehyde removal agent, the number of visitors increased by 15%.
4.3 Data support
The following table shows the comparison of user satisfaction before and after the use of polyurethane sponge aldehyde remover in subway stations, hospitals and schools in a city:
| Type of place | User satisfaction before use | User satisfaction after use | Satisfaction improvement ratio |
|---|---|---|---|
| Subway Station | 75% | 90% | 20% |
| Hospital | 80% | 95% | 18.8% |
| School | 85% | 98% | 15.3% |
