Surface treatment workshop (anodizing)

Surface treatment process: put the metal parts into the degreasing tank with degreasing agent, the concentration of degreasing agent in the degreasing tank is 4-6%, the temperature is 25-65 ℃, and the soaking time is 2-4 minutes. Apply grease on the surface of the oil tank and clean up the residue at the bottom of the oil removal tank every quarter of the time.

Spray the immersed metal parts with degreasing agent for 2-5min, the concentration of degreasing agent is 3-5%, the temperature is 15-65 ℃, and the pH value is 10. After spraying twice, the surface of metal parts is cleaned, and the cleaned metal parts are put into the solid film tank with solid film agent. The concentration of solid film agent in the solid film tank is 2-3%, and the pH is 8-9, and the solid film agent is sprayed for 1-3 minutes.

The product does not contain phosphorus, nitrite and harmful metals. The discharged sewage meets the environmental protection standard and can be operated at room temperature. It has the advantages of energy saving and environmental protection.

After processing, the surface of the workpiece forms a transparent dense layer, the oxide film and organic film are uniform, and the salt spray performance reaches or exceeds the traditional phosphating and silane treatment, which overcomes the shortcomings of poor corrosion resistance of environmental protection treatment agents used in industry, greatly improves the corrosion resistance of products and meets the needs of customers.
