Background of silane ceramic agent. Before painting, steel usually needs pretreatment, including degreasing, derusting and other processes. Chemical pretreatment of heavy oil cleaning agent usually needs to form a chemical conversion film on the surface of steel. The conversion film has a certain anti-corrosion ability, which can avoid the parts from rusting in a short time before spraying, and can also increase the surface roughness of parts and enhance the coating and substrate The combination of the two.
The new technology of zirconia conversion film has been successful in the laboratory, and full-scale production test is in progress. The new conversion film is composed of amorphous ZrO2 instead of zn3 (PO4) 2 polycrystalline. It mainly uses nano ceramic coating composed of zirconia to replace the traditional crystalline phosphating protective layer. It has good adhesion with metal surface and subsequent paint coating, and has excellent corrosion resistance. It is believed that the application of zirconia conversion coating technology will bring great changes to the pretreatment process of iron and steel industry.
The application of non phosphorus film-forming technologies such as silylation and vitrification has changed the chemical conversion film technology on steel surface. It is believed that these phosphating processes will not be developed in the near future.
