The environmentally-friendly metal surface treatment series of biological agents developed and produced by the company use environmentally-friendly biological degreasing, rust removal, and magnetization film forming technology to make the product surface corrosion resistance, adhesion and impact resistance and other indicators can meet higher requirements . Because the process is environmentally friendly, stable, and easy to operate, it replaces the traditional processes of pickling, phosphating, silane and other multiple processes in metal surface treatment, and heavy pollution is not conducive to environmental protection and long-term development of enterprises.

SVJ—Biophysical and chemical color film agent

       Using bio-physical methods to quickly form a dense physical and chemical color crystalline film on the metal surface, which has excellent corrosion resistance within a certain period of time, and the physical and chemical crystalline color film is firmly combined with the base metal, which can effectively change the physical and chemical properties of the metal surface. So that the surface will not rust before the anti-corrosion construction, and the surface bonding force of the paint film and the protective layer can be improved.

Use Cases

SVJ—Rust Remover

       This product is composed of a variety of surfactants "AEO", high-efficiency additives, organic acids, etc., and a special corrosion inhibitor is added to the acid medium to have a comprehensive treatment function for oil and rust removal. It can effectively remove all kinds of oil stains, stains and rust layers at room temperature, and overcome the shortcomings of the traditional use of strong acid and alkali, high temperature degreasing and rust removal, and the danger of over-corrosion and hydrogen embrittlement. The use of oil rust cleaner can effectively prevent hydrogen embrittlement and over-corrosion, and improve the effect of oil removal and rust removal.
