Problems solved by technology

[0002] At present, the cleaning of stainless steel cold-rolled parts is difficult to control. In order to remove the sintered matter and dirt inside and outside the tube, the traditional method is to use nitric acid and hydrofluoric acid for heating. The smaller the tube, the more difficult it is to clean.
Strong acid is highly corrosive to the surface of stainless steel cold-rolled parts. Often the outside of the tube has been cleaned, but the sintered material inside the tube has not fallen off. After a long time, the sintered material in the tube has fallen off, and the outside of the tube has been severely corroded; and due to nitric acid and hydrogen Fluoric acid is heated to produce acid mist, which not only has great harm to the human body, but also seriously pollutes the air, and the discharge of waste acid water also seriously pollutes water resources

Abstract

The invention relates to the technical field of chemical cleaning, in particular to a cleaning agent suitable for a stainless steel cold-rolling piece and a preparation method thereof. The cleaning agent for the stainless steel cold-rolling piece is manufactured at normal temperature by mixing the following raw materials by weight percentage: 31.6 percent to 65.8 percent of water, 7 percent to 14 percent of citric acid, 11 percent to 22 percent of oxalic acid, 0.2 percent to 0.4 percent of sodium molybdate, 5 percent to 10 percent of triethanolamine, 8 percent to 16 percent of fatty alcohol-polyoxyethylene ether, 1 percent to 2 percent of alkylphenol ethoxylates, 1 percent to 2 percent of hydrochloric acid and the balance of hydrofluoric acid. The chemical cleaning and the preparation method have the advantages that the operation is simple, the cleaning effect is good, the surface of the stainless steel cold-rolling piece cannot be corroded at the same time, and the glossiness of the stainless steel cold-rolling piece is maintained; the cleaning agent for the stainless steel cold-rolling piece can be repeatedly used and cannot harm skin when being contacted with the skin; and as not containing zinc or nitrogen, the cleaning agent is low-carbon and environmentally friendly, and the cost is saved.
