Heat treatment, conversion treatment and application of lubricants are key processes

The production capacity of ABS strips depends on the throughput of these processes. In addition to the solid solution and annealing functions, the heat treatment process should also have the function of producing T4P (pre-aging) coils, which is a unique state for the production of heat-treatable reinforced ABS strips. The conversion treatment is chemical oxidation treatment in the fluorozirconium/titanic acid mixture to form a passivation film on the aluminum surface. The base chemical elements are titanium, zirconium, aluminum, oxygen and fluorine. The mass of the film is 1~4mg/ dm, density 2.8g/cm, thinner than the anodic oxide film, but much thicker than the natural oxide film, colorless or slightly blue, is a good base for adsorption and lubrication, and has good corrosion resistance, can be very good To protect the ABS strip from corrosion during the shelf life (6 months).
