The working principle of waterproof breathable membrane:

In the state of water vapor, the water particles are very small. According to the principle of capillary motion, it can smoothly penetrate into the capillary to the other side, so that the vapor permeability phenomenon occurs. 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 cannot smoothly escape from the water droplets and penetrate to the other side, which is to prevent The penetration of water occurs, so that the vapor-permeable membrane has a waterproof function.

Material of waterproof breathable membrane:

The technology of waterproof and breathable membrane was first introduced from European and American countries. However, the production process of domestic products is diverse, and the quality of various manufacturers' products is uneven, which has not formed a unified quality standard. In fact, the waterproof and breathable film mainly consists of three layers: PP spunbond non-woven fabric, PE polymer breathable film, and PP spunbond non-woven fabric. The function of spunbond non-woven fabric is mainly to enhance the tensile force and hydrostatic pressure and protect the middle layer (breathable film). The real breathability mainly depends on the middle layer PE polymer breathable film.

Production process of waterproof and breathable membrane:

There are three main types: 1. Casting compound. This process relies on the viscous compounding of the plastic itself after the plastic particles are hot-melted. The disadvantage is that it is almost impermeable. In 2014, there was no way around the world to be able to use this process to produce truly high-permeability, high-temperature, waterproof, and breathable membranes. 2. Spray or scrape compound (hot melt compound). This process was first applied to sanitary napkins, urine non-wetness, and protective clothing. At present, almost all domestic manufacturers use this process to produce highly breathable waterproof and breathable materials. The disadvantage is that the air permeability is relatively low, because the pores of the intermediate air-permeable membrane are actually blocked by hot melt glue. In addition, the most fatal disadvantage is that the temperature resistance is very low, which can only withstand a temperature of 60 degrees. Because this glue is actually a pressure-sensitive adhesive (self-adhesive). A simple example is that in winter, the double-sided tape has almost no stickiness and will delaminate, but in summer, the adhesive on the surface of the double-sided tape will melt. The quality of the waterproof and 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 delaminated. 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 and breathable membrane can only be a fake and inferior product of real waterproof breathable membrane, and there is no market in Europe and the United States at all. 3. Hot pressing compound. At present, the domestic market is mixed, and there are actually very few manufacturers producing genuine waterproof and breathable membranes. Many factories or sellers say that their waterproof and breathable membranes are good. Almost most users have never thought of them. Some manufacturers' waterproof and breathable membranes are not waterproof at all. . For example, a domestic colleague of ours deceives consumers into saying what an international company is and uses the technology and R & D achievements of a well-known international company. In fact, the static pressure of the waterproof and breathable membranes they produce is only about 750px, but users do not know how to detect. I only know that water is splashed on the waterproof and breathable membrane. This membrane does not leak. In fact, where does the user know that water is pressure and will penetrate. The method is to check each batch of waterproof and breathable membranes for inspection. . In fact, the real waterproof and breathable membrane should be highly breathable, high temperature resistance, anti-aging, and the hydrostatic pressure should be more than 2 meters.
