The fire-resistant metal zipper process is a method of combining metal materials with fire-resistant materials. The tape material of the fire-resistant metal zipper usually uses aramid, which is a synthetic fiber material with high temperature resistance. First, the aramid fibers are subjected to textile processing to produce tapes of certain specifications and sizes. Then, the metal teeth are fixed on the aramid tape. To enhance the fire resistance, a layer of fire-resistant material, such as a flame retardant, can be coated on the surface of the tape to improve the fire resistance of the zipper. The entire process requires strict control of temperature and manufacturing parameters to ensure that the zipper has excellent performance such as high temperature resistance, fire resistance, and abrasion resistance, making it suitable for fire protection equipment and use in high-temperature environments.
