PTFE waterproof and breathable membrane, as the name suggests, can be both waterproof and breathable.
The main reason is that its micropores are much smaller than water vapor molecules, so water vapor molecules can freely shuttle through the micropores, thereby taking away heat and preventing water vapor from condensing inside.
Practice has proven that no matter what facade form or roof laying form is adopted, the airtightness of the building envelope cannot be guaranteed.
For exterior walls, cracking of plastering is inevitable, it is difficult to tightly overlap the hanging boards, and simple masonry blocks cannot achieve an “airtight wall”.
These problems are more obvious at the yin and yang corners of the building, at the overlaps and around doors and windows.
Through these unsealed pores, airflow and water vapor can invade the building envelope, thus having a serious impact on the energy consumption, durability and comfort of the building.
The ptfe waterproof and breathable membrane is a purely physical barrier and does not rely on static electricity. When the user inhales, the 100~200 nanometer pores will physically filter PM2.5 to PM0.3 and block it on the surface of the mask. Due to the super self-lubricating characteristics of PTFE material, every exhalation will reversely push the particles attached to the surface of the mask back into the environment. Repeatedly, it does not rely on electrostatic adsorption, truly achieving effective PM2 removal. .5Protective effect.
