Abstract

The invention relates to the technical field of chemical cleaning, in particular to a cleaning agent for stainless steel seamless stay tubes and a preparation method for the cleaning agent. The cleaning agent for the stainless steel seamless stay tubes is prepared by mixing the following raw materials in percentage by weight at normal temperature: 45.5 to 72.75 percent of water, 1 to 2 percent of alkylphenol polyoxyethylene, 2.5 to 5 percent of citric acid, 5 to 10 percent of oxalic acid, 2.5 to 5 percent of sodium molybdate, 5 to 10 percent of triethanolamine, 7.5 to 15 percent of fatty alcohol-polyoxyethylene ether, 3 to 6 percent of tartaric acid, 0.25 to 0.5 percent of nitric acid, 0.25 to 0.5 percent of hydrofluoric acid and the balance of hexamethylenetetramine. The cleaning agent for the stainless steel seamless stay tubes has novel process, is easy to operate and strong in cleaning force, does not need to be heated, can be reused, can be used for cleaning the stainless steel seamless stay tubes without corroding the surface of stainless steel, and keeps the glossiness of the stainless steel; and the cleaning agent for the stainless steel seamless stay tubes has no injury to the skin, is low-carbon and environment-friendly, has high cost performance, and saves the cost.

Description

Technical field [0001] The invention relates to the technical field of chemical cleaning, in particular to a cleaning agent suitable for seamless drawn stainless steel pipes and a preparation method thereof. Background technique [0002] At present, stainless steel seamless drawn tubes are difficult to clean, especially the first-level capillary produced in the first process. Because the inner and outer surface layers of the capillary are pinhole-like, the pinholes must be cleaned. If the first process is not cleaned , It will bring quality problems to the second and third continuous drawing pipes, resulting in leakage of the finished stainless steel seamless drawn pipes. The traditional cleaning agent formula is nitric acid, hydrofluoric acid, hydrochloric acid and water in a mass percentage of 5:4:3:8 and then heated to 65°C. The stainless steel seamless drawn pipe to be cleaned needs to be soaked for 1.5 hours to be cleaned. As the concentration of the cleaning agent decrease...
