Problems solved by technology

[0004] Stainless steel has low hardness and is a metal that is difficult to polish. The traditional method is to use mechanical polishing and electrolytic polishing, but the conditions are often not available on site, and mechanical polishing and electrolytic polishing cannot be used. It is more convenient to choose chemical polishing as a polishing method. The stainless steel polishing agent used in the existing chemical polishing has poor polishing ability, poor dispersion of abrasives, poor composition stability, and serious dust phenomenon after polishing.

Abstract

The invention relates to a polishing agent, in particular to a stainless steel material polishing agent and a preparation method thereof. Each liter of the polishing agent solution is composed of 5-9 g/L of ferric trichloride, 80-150 ml/L of concentrated hydrochloric acid, 30-60 ml/L of concentrated nitric acid, 18-26 g/L of emery, 20-40 ml/L of tetra-polyricinoleate, 12-18 ml/L of organic polymeric tribasic carboxylic acid, 5-12 ml/L of triethanolamine, 30-80 ml/L of ethylene glycol, 10-25 ml/L of composite additives, and the balance water. The polishing agent provided by the invention is environmentally friendly, efficient and convenient to use.

Description

technical field [0001] The invention relates to a polishing agent, in particular to a stainless steel material polishing agent and a preparation method thereof. Background technique [0002] The microstructure of metal materials directly affects the performance and service life of mechanical parts. Metallographic analysis is an important means to control the internal quality of mechanical parts. In the research and development of new materials, new processes, and new products, and in the scientific research to improve the internal quality of metal products, metallographic technical analysis is inseparable. [0003] In the process of metallographic technical analysis, polishing is a very important step. Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. The purpose of polishing is to remove the grinding marks on the metallographic grinding su...
