Problems solved by technology

For processing about 2 tons of stainless steel hot-rolled parts, the treatment time of the newly prepared cleaning agent is 1.5 hours. After a period of use, the processing time needs to be extended to 6 hours. At this time, the cleaning agent must be completely discharged, and this strong acid The cleaning agent will also corrode the surface of the stainless steel hot-rolled parts. Because nitric acid and hydrofluoric 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 seriously pollutes water resources.

Abstract

The invention relates to the technical field of chemical cleaning, in particular to a cleaning agent applicable to a stainless steel hot-rolled member and a preparation method thereof. The cleaning agent for the stainless steel hot-rolled member is prepared by mixing the following raw materials in percentage by weight at a normal temperature: 36.8%-68.4% of water, 3.5%-7% of citric acid, 10%-20% of fatty alcohol polyoxyethylene ether, 5%-10% of tartaric acid, 5%-10% of triethanolamine, 0.1%-0.2% of sodium molybdate, 1.5%-3% of hydrochloric acid, 1%-2% of hydrofluoric acid, 5%-10% of oxalic acid and the balance of alkylphenol polyoxyethylene. The cleaning agent for the stainless steel hot-rolled member is simple and convenient in operation, novel in process, strong in cleaning capability and harmless in skin contact; the personal safety of an operator is effectively guaranteed; the warming is not needed; the cleaning effect is good; synchronously, the surface of stainless steel is not corroded; the glossiness of the stainless steel is maintained; furthermore, the cleaning agent for the stainless steel hot-rolled member can be used repeatedly and is low-carbon and environment-friendly; and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning, in particular to a cleaning agent suitable for hot-rolled stainless steel pieces and a preparation method thereof. Background technique [0002] At present, stainless steel hot-rolled parts are difficult to clean. From the first manufacturing process such as capillary, it needs to be cleaned. Nitric acid, hydrofluoric acid and water are mixed in a weight percentage of 6:3:11 and heated to 65°C. , Submerge the workpiece to be treated in the cleaning agent. For processing about 2 tons of stainless steel hot-rolled parts, the treatment time of the newly prepared cleaning agent is 1.5 hours. After a period of use, the processing time needs to be extended to 6 hours. At this time, the cleaning agent must be completely discharged, and this strong acid The cleaning agent will also corrode the surface of hot-rolled stainless steel parts. Because nitric acid and hydrofluoric acid are heated to ...
