2、 Main features


1. Steel oil removal, rust removal, phosphating one process.


2. A phosphate film can be formed on the surface of the treated steel, which has a strong antirust function.


3. Non toxic, no environmental pollution, no over corrosion.


4. The solution is stable and easy to control.


5. It does not affect the original mechanical properties and welding properties of steel, and can enhance the adhesion between paint film and metal surface.


3、 Application method and process parameters


1. This product is working fluid, pour into the tank can be used. The operation mode can be tank immersion or scrubbing.


2. Process parameters: TA ≥ 300pt, service temperature 35 ~ 45 ℃


3. When the agent is used for brushing phosphating, the dosage can be flexibly controlled according to the severity of oil stain and corrosion. In general, dip the liquid medicine with a brush and brush it on the steel surface evenly, then wipe the water and residual medicine on the surface with a rag immediately. In case of serious corrosion, it can be painted repeatedly for several times. The phosphated steel surface can be protected by phosphate film to improve the corrosion resistance of the workpiece.
