It is very necessary to add an anti-corrosion layer to waterproof tiles, because the anti-corrosion layer can effectively protect the tiles from the erosion of chemicals, moisture and ultraviolet rays in the environment, thereby extending the service life of the tiles. The anti-corrosion layer can also prevent the cracking, deformation and aging of the tiles due to corrosion, maintaining their structural integrity and functionality. In addition, the anti-corrosion layer can reduce the frequency of maintenance and replacement, reduce long-term use costs, and improve the overall durability and safety of the building.
Many customers will choose to add a PE anti-corrosion layer on the back of the waterproof tile, but the PE anti-corrosion layer has poor high temperature resistance and is prone to failure in high temperature environments; the UV resistance is insufficient and it will age after long-term exposure to sunlight; the mechanical strength is low and it is easily damaged by external forces; the adhesion to other materials is weak, which may cause peeling; it becomes brittle in low temperature environments, affecting its service life; therefore, the chemical corrosion resistance of PE materials is limited and cannot be applied to all chemical environments.
Himei waterproof tiles are added with PVDP film with stronger anti-corrosion performance during production. It has excellent chemical corrosion resistance and can resist most acids, alkalis and organic solvents; excellent weather resistance and UV resistance, suitable for long-term outdoor use; good mechanical strength and toughness, able to withstand various mechanical stresses; high temperature resistance, can maintain stable performance in high temperature environment; excellent electrical insulation performance; self-cleaning performance, the surface is not easy to be contaminated, which helps to maintain long-term beauty and stable performance.
