Problems solved by technology

The chemical polishing liquid currently used is composed of strong acid or strong alkali, such as sulfuric acid, hydrochloric acid, nitric acid, etc., which will produce a large amount of harmful gas during the polishing process, such as the polishing liquid containing nitric acid will produce a lot of yellow smoke during use , causing serious pollution to the environment
At present, there are also polishing solutions that do not use nitric acid, but strong acids or alkalis such as sulfuric acid and hydrochloric acid are added to them, and there are high requirements for the use environment and operation during use.
At present, there is no more efficient mild polishing fluid on the market

Abstract

The invention discloses a polishing solution and a polishing method thereof, wherein the polishing solution comprises the following components in parts by weight: 10-20 parts of sodium doodecyl benzene sulfonate, 10-15 parts of acetic acid, 0.5-2 parts of organosilicon foam killer, 3-8 parts of sodium tripolyphosphate, 5-10 parts of polyethyleneglycol 2000, 5-10 parts of glycerol, 3-8 parts of hexamethylene tetramine, 3-6 parts of cupric sulfate, 5-10 parts of p-hydroxybenzoic acid, 15-20 parts of citric acid, 3-8 parts of ammonium chloride and 100-120 parts of solvent. A stainless steel surface polished with the polishing solution is clean and bright, has higher weatherability, and meanwhile achieves higher service efficiency and a longer service life.

Description

technical field [0001] The invention belongs to the technical field of polishing, in particular to a polishing liquid and a polishing method thereof. Background technique [0002] Stainless steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acids, alkalis, and salts. At present, there are many products of stainless steel materials, the shapes of parts are complex and diverse, and there are many processes in the processing process. Stainless steel will inevitably produce scratches, bruises, etc. during use, which makes stainless steel products unable to be used normally. Due to the complex and diverse shapes and sizes of stainless steel parts, the traditional mechanical polishing method can no longer meet the requirements of the product, and the electrolytic polishing method cannot meet the requirements of products with a certain size, and the uniformity of electrolytic polishing is relatively poor.
