Breathable waterproof membrane walls

Breathable waterproof membrane walls

In the state of water vapor , very small water particles , based on the principle of capillary movement, penetrate into the capillary can be smooth on the other side , so that the occurrence of the phenomenon of vapor permeability . When the condensation of water droplets become particles becomes large , the effect of the surface tension of water droplets , the water molecules can not penetrate the drops smoothly from the other side , that is, to prevent the occurrence of water infiltration , so that the vapor permeable membrane have waterproof function .
Breathable waterproof membrane works:
In the state of water vapor , very small water particles , based on the principle of capillary movement, penetrate into the capillary can be smooth on the other side , so that the occurrence of the phenomenon of vapor permeability . When the condensation of water droplets become particles becomes large due to the action of surface tension of water droplets ( water molecules with each other " counter pull " ) , the water molecules can not penetrate the drops smoothly from the other side is prevented from water penetration occurs , so that the film has been vapor- permeable waterproof function .
Waterproof breathable membrane process: 1, advanced production technology : waterproof breathable membrane using advanced thermal composite production process which is a national initiative , no glue solvent-free compound , the international advanced . 2 , excellent anti-aging properties : breathable waterproof membrane in the construction process , will withstand high temperatures and strong ultraviolet double test , even in the pavement has been completed, it would have long been in contact with the exchange of hot and cold air , so good anti- aging properties are necessary conditions and product quality assurance. Breathable waterproof membrane , through the national testing center for testing of building materials , products, strong ultraviolet radiation by 500 hours , 2160 hours 100 degree high temperature test, ensuring the durability and life of waterproof breathable membrane.
