Driven by science and technology, survive by quality
Polypropylene films of spunbond polyethylene and polypropylene films generally refer to biaxially oriented polypropylene films. Biaxially oriented polypropylene films (BOPP) are usually multilayer pneumatic films. After polypropylene particles are pneumatically formed into sheets, they pass through two directions. The stretched film has excellent physical stability and mechanical strength because of the stretched molecular direction.
How to use the breathing paper?
Breathing paper ensures the thermal insulation performance of the building, improves the air quality of the room, and makes the living environment more warm. The waterproof vapor barrier film must have good air tightness. It can help prevent airflow intrusion, reduce energy consumption, and prevent moisture from overflowing the wall.
How is the waterproof vapor barrier film waterproof?
The working principle of the waterproof vapor barrier membrane can be divided into two types: microporous and hydrophilic groups. The waterproof and breathable membrane adopts the former, because the minimum diameter of water droplets is about 20 microns, while the diameter of water vapor molecules is only about 0.0004 microns. , There is a huge difference between the diameters of the two, water vapor can pass through the microporous membrane by the principle of diffusion, and liquid water or water droplets are due to the effect of surface tension.
In today ’s world, there are many challenges: land desertification, ozone hole, air pollution,ocean pollution, global warming, energy crisis ... While humans have made great progress,in material creation, they have brought many negative effects to the earth ’s environment and ecology Impact.
