Waterproof and breathable membrane can prevent the appearance of aging and oxidation

The pores of the waterproof and breathable membrane are actually blocked by hot melt adhesive. In addition, the disadvantage of death is that the temperature resistance is very low, and it can only accept a temperature of 60 degrees. Since this glue is actually a pressure sensitive adhesive (self-adhesive). A simple example is that in winter, the double-sided tape is almost non-sticky and will delaminate, but in summer, the glue on the surface of the double-sided tape will melt. The quality of the waterproof breathable membrane made by this process can be imagined. During construction, as long as there is a certain temperature, the non-woven fabric will be glued and layered. Which construction company can guarantee that the roof will be covered as soon as the waterproof and breathable membrane is laid during construction? Therefore, this waterproof breathable membrane can only be a fake and shoddy product of the real waterproof breathable membrane, and there are no shopping malls in European and American countries. 3. Hot pressing compound. Domestic shopping malls are mixed, and there are actually very few manufacturers producing real waterproof and breathable membranes. Many factories or sellers say that their waterproof and breathable membranes are good. For example, our domestic counterparts deceive customers into saying that it is a world company, and use the technology and research and development of a world-renowned company. In fact, the hydrostatic pressure of the waterproof and breathable membrane produced by them only needs about 750px, but the user does not know how to detect it. I only know that water is poured on the waterproof and breathable membrane, and this membrane does not leak. In fact, how does the user know that water is under pressure and will permeate. The method is to inspect each batch of waterproof and breathable membranes, so that fake and inferior products can not hide.

The main application function of the waterproof breathable membrane must be waterproof. Because of the micropores of 0.1 to 1.0 microns, there is no way for water molecules to pass through, which means that it can effectively protect the active parts, which can not only prevent aging and oxidation, but also Preventing being corroded by various liquids can not only increase the service life of the product, but also make the application function reach a better standard, relatively prevent various defects and bring better application effect. The application of waterproof breathable membrane can be said to be very extensive.

The air permeability and dustproof effect is also a serious feature. Because the pore size of the pores is 700 times larger than that of water vapor, the air permeability is also very good in waterproofing and heat dissipation. The dust barrier effect is particularly good, because the internal structure constitutes a special mesh three-dimensional structure, so that the dust is blocked, it will naturally be effective for dust prevention and prevent accidents.
