Stainless steel seamless extruded tube cleaning solution and preparation method thereof

Abstract

The invention discloses a cleaning solution suitable for a stainless steel seamless extruded tube and a preparation method thereof. The stainless steel seamless extruded tube cleaning solution is prepared by mixing the following raw materials by weight percent at normal temperature: 70-80% of water, 0.5-1.5% of alkylphenol ethoxylates, 1-3% of citric acid, 1-3% of sodium molybdate, 4-8% of triethanolamine, 7-12% of fatty alcohol polyoxyethylene ether, 1-3% of tartaric acid, 0.2-1% of trisodium phosphate, 0.5-1.5% of ethanol, 0.1-0.5% of nitric acid, 0.1-0.5% of hydrofluoric acid and the balance of hexamethylenetetramine. The preparation method is simple to operate, dispenses with heating, is good in cleaning effect, simultaneously avoids corroding the surface of stainless steel and maintains the glossiness of stainless steel. The stainless steel seamless extruded tube cleaning solution can be reused, causes no damage to skin when coming into contact with the skin, is low-carbon and environment-friendly and saves the cost.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning, in particular to a cleaning liquid suitable for stainless steel seamless extruded pipes and a preparation method thereof. Background technique [0002] At present, the cleaning of stainless steel seamless extruded tubes is difficult to control. In order to remove the sintered matter and dirt inside and outside the tubes, the traditional cleaning agent formula is mixed with nitric acid, hydrofluoric acid, hydrochloric acid and water in a mass percentage of 5:4:3:8. When heated to 65°C, the stainless steel seamless pipe to be cleaned needs to be soaked for 1.5 hours before it can be cleaned. As the concentration of the cleaning agent decreases, the cleaning time will be prolonged. Because nitric acid, hydrofluoric acid and hydrochloric acid are heated to produce acid mist, it is very harmful to the human body, and it seriously pollutes the air, and the discharge of waste acid water also s...
