It is widely used in steel structure factory buildings, opera houses, railway stations, bus stations, airport terminals, libraries, stadiums, large exhibition centers, wood structure houses, light steel villas, various dry hanging material curtain walls, etc.
Waterproof breathable membrane is a new type of polymer waterproof material. From the production process, the technical requirements of waterproof breathable film are much higher than those of ordinary waterproof materials; In terms of quality, waterproof breathable film also has other Waterproof materials have unique characteristics. While strengthening the air and water tightness of buildings, the waterproof breathable film has unique vapor permeability, which can rapidly discharge the water vapor inside the structure, protect the property value, and solve the problem of moisture-proof and human health. It is a new type of healthy and environment-friendly energy-saving material.
Waterproof breathable membrane Operating principle of:
In the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate to the capillary to the other side, thus causing the phenomenon of vapor permeability. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull against each other"), the water molecules can not be separated from the water droplets and permeate to the other side smoothly, which prevents the water infiltration and makes the vapor permeable membrane waterproof.
Process of waterproof breathable film:
1. Advanced production process: the waterproof breathable film adopts advanced thermal composite production process, which belongs to the domestic * * *, no glue and solvent composite, all advanced. 2. Excellent anti-aging performance: During the construction process, the waterproof breathable film will certainly withstand the double test of strong ultraviolet and high temperature. Even after the pavement is completed, it will also be exposed to and exchanged with cold and hot air for a long time. Therefore, good anti-aging performance is the necessary condition and quality guarantee for the product. The waterproof breathable film has passed the test of the National Building Materials Test Center. The product has been tested by 500 hours of strong ultraviolet radiation and 2160 hours of 100 ℃ high temperature, ensuring the durability and service life of the waterproof breathable film.
