Product introduction: Medium temperature black anti-rust and wear-resistant phosphating liquid
For a long time, high-temperature oxidation is usually used to turn the surface of ferrous metal materials (including steel and cast iron) black.
The process solution system is stable, the operation requirements are not high, and the appearance of the film layer is beautiful. But at the same time, there are insurmountable defects: high energy consumption, low efficiency, corrosion resistance not as good as that of phosphating film, and the blackening of cast iron parts is usually dark brown or reddish brown. The colors after processing of different materials cannot be consistent.
In particular, it causes great harm and damage to the working environment and environmental protection of operators (the presence of carcinogens, the generation of a large amount of alkali mist), etc. In response to these shortcomings that urgently need to be solved, we have researched and developed normal temperature blackening technology. This technology has the advantages of energy saving, simple operation, and short film formation time.
However, there are also obvious shortcomings: high pre-treatment requirements and strong selectivity for steel materials. For spring steel, heat-treated and quenched steel, etc., a black film with various indicators comparable to or better than high-temperature alkaline oxidation can be obtained. However, for most steel materials, compared with alkaline oxidation, the wear resistance and corrosion resistance are poor. To be worse.
In order to obtain a black film with good wear resistance, corrosion resistance and uniform color, we have absorbed the advantages of the phosphating process and the normal temperature blackening process and have gone through a lot of experiments. , researched and produced a new medium and high temperature black phosphating process and put it into mass production.
This product forms a (phosphate) composite film with good corrosion resistance on the surface of steel, with good corrosion resistance and strong adhesion. It overcomes the disadvantages of high energy consumption, low efficiency and high pollution of alkaline blue hair. The operation process is simple and it is an ideal product for anti-corrosion and decoration of steel surfaces.
Main uses: This product is a phosphating liquid with strong anti-rust and wear resistance. After this phosphating treatment, and then applied with anti-rust oil, it can prevent rust for years
