Problems solved by technology

At present, the existing electrochemical polishing in most factories cannot be mass-produced due to energy consumption. At the same time, the appearance of stainless steel products is complicated. When electrochemical polishing is used to polish parts with blind holes, the surface of the inner hole is Low current density area, unable to achieve satisfactory polishing effect on its inner surface
Mechanical polishing is generally more polluting and requires more workers. Although electro

Abstract

The invention relates to a chemical polishing agent for stainless steel product surface polishing, a preparation method and a polishing method thereof. The chemical polishing agent is prepared by adding 13-20 g/L of ammonium bifluoride, 85-110 mL/L of nitric acid, 110-130 mL/L of phosphoric acid, 140-160 mL/L of hydrochloric acid, 20-30 g/L of sodium chloride, 85-95 mL/L of hydrogen peroxide, and 25-40 mL/L of a composite additive to water, wherein the composite additive contains 4-6 g/L of hexamethylenetetramine, 10-15 g/L of polyethylene glycol, 10-12 g/L of urea, 5-7 g/L of sulfosalicylic acid, and 4-8 g/L of an OP emulsifying agent. According to the present invention, surface flatness and glossiness of a stainless steel work-piece are increased, consumption of a large amount of electric energy is not required, chromic anhydride toxic substances are not generated, and waste water treatment requirements are reduced.

Description

technical field [0001] The invention relates to a mixed solution for polishing the surface of stainless steel products which is composed of various chemical substances, in particular to a chemical polishing agent, a preparation method and a polishing method for polishing the surface of stainless steel products. Background technique [0002] Stainless steel is a metal that is difficult to polish. The polishing methods that are often used are mechanical polishing and electrochemical polishing. At present, the existing electrochemical polishing in most factories cannot be mass-produced due to energy consumption. At the same time, the appearance of stainless steel products is complicated. When electrochemical polishing is used to polish parts with blind holes, the surface of the inner hole is In the low current density area, satisfactory polishing effect cannot be achieved on the inner surface. Mechanical polishing is generally more polluting and requires more workers. Althoug...
