The membrane material connection of the sewage tank cover is usually heated by the heat method. The heat method guarantees the seamless connection between the membranes and the cutting is satisfactory. Adhesive bonding, mechanical stitching and other methods have poor durability, and mechanical stitching is easy to leave needle holes and affect the sealing effect. So what are the benefits of using thermal law?
1. The heat welding method of the membrane material is similar to the welding principle of the steel structure, and the heating body welding is adopted, and the tensile and tear strength are much higher than other connection methods.
2. Heat welding is to use the material of the film itself for welding, and the sealing effect is good.
3. Good performance of the membrane material: The membrane material used for the cover of the sewage tank has a three-layer structure, with a fabric layer in the middle and a PVC coating layer on the outside, which is easy to weld and strong.
4. Environmental protection membrane materials: The membrane materials used in the deodorization of sewage tank waste gas are all environmental protection membrane materials, and will not pollute the air during the heat-sealing splicing process.
