　　The working principle of waterproof breathable membrane: In the state of water vapor, water particles are very strong, and according to the principle of capillary motion, they can smoothly penetrate to the other side of the capillary tube, thus causing the phenomenon of vapor permeation. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (water molecules "pull and resist" each other), water molecules cannot smoothly detach from the water droplets and penetrate to the other side, which prevents water infiltration and gives the vapor permeable membrane waterproof function. The material of waterproof breathable membrane: The technology of waterproof breathable membrane has been introduced since Europe and America. However, the production process of domestic products is varied, and the products of various manufacturers are uneven, without forming a unified one. In fact, waterproof breathable film mainly consists of three layers: PP spunbond non-woven fabric, PE polymer breathable film, and PP spunbond non-woven fabric. The main function of spunbond non-woven fabric is to enhance tensile strength, hydrostatic pressure, and protect the middle layer (breathable film). True breathability mainly relies on the middle layer PE polymer breathable film. Waterproof breathable membrane welding machine, breathable membrane filtration cotton hot melt welding equipment adopts a suction plate structure and applies electric heating. The whole machine is in the form of a frame, consisting of three large plates: an upper template, a lower template, and a hot template, and is equipped with a hot mold and upper and lower plastic cold molds, which are controlled by pneumatic control. Mainly suitable for welding plastic parts such as household appliances, car lights, and automotive solvents. Heating power and mold size can be set according to different sizes of plastic parts to achieve welding of various plastic workpieces, with simple operation and convenient use.
