Solid welding wire surface degreasing and rust removing mixed cleaning agent, manufacturing method and use method thereof

Abstract

The invention discloses a solid welding wire surface degreasing and rust removing mixed cleaning agent, a manufacturing method and a use method thereof, wherein per L of the mixed cleaning agent comprises: 120-180 g of sulfuric acid, 15-20 g of peregal, 0.03-0.07 g of sodium lauryl sulfate, 1-10 g of citric acid, 0.5-2.0 g of thiourea, and the balance of water. The manufacturing method comprises:preparing sulfuric acid with a mass percent concentration of 98%; weighing the sulfuric acid according to the ratio of 120-180 g of the sulfuric acid in per liter of the mixed cleaning agent; and sequentially adding peregal, sodium lauryl sulfate, citric acid, thiourea and water to the sulfuric acid. The use method comprises: pouring the mixed cleaning agent into a cleaning groove, heating the mixed cleaning agent in the cleaning groove to a temperature of 40 DEG C, and cleaning at a single welding wire electrolysis tic current of 18 A after a to-be-cleaned solid welding wire penetrates through the mixed cleaning agent. A purpose of the present invention is to solve the problems of environment pollution caused by acids and alkalis, high treatment cost, multiple process control points, large cross-effects, large fluctuations in cleaning quality, and the like in the prior art.

Description

technical field [0001] The invention relates to a solid welding wire mixed cleaning agent, in particular to a solid welding wire surface degreasing and derusting mixed cleaning agent, a manufacturing method and a using method. Background technique [0002] At present, the surface treatment process commonly used by various solid welding wire manufacturers is mainly electrolytic alkali washing for degreasing combined with electrolytic pickling for rust removal. Rust removal and degreasing are often carried out separately, and there are problems such as large equipment footprint, environmental pollution by alkaline and acid solutions, high processing costs, many process control points and cross-effects, and large fluctuations in cleaning quality. [0003] How to simultaneously degrease and derust the surface of the solid welding wire, reduce production costs, simplify operation steps, improve operation effects, and reduce environmental pollution are problems to be solved by tho...
