Problems solved by technology

In the pickling process, due to the strong volatility of the pickling liquid, even if the production environment is ventilated by opening windows and using a strong exhaust device, the effect is very small. A large amount of acid mist is volatilized, which seriously affects the safety of other equipment in the workshop. service life, so that the cost of equipment maintenance continues to increase, greatly increasing the cost

Abstract

The invention discloses a part cleaning agent including the following main ingredients by mass: 420 parts of toluene, 200 parts of methanol and 380 parts of dichloromethane, and the part cleaning agent is prepared by the following method: cleaning a preparation reaction kettle to be clean and waterless, then successively adding the qualified raw material toluene, methanol, and dichloromethane, and stirring and mixing evenly at normal temperature for 5 to 10 minutes; stopping stirring, standing the raw materials for 5 minutes, and sampling for inspection; and after the inspected sample is qualified, using a 300 mesh filter screen to filter for producing and filling. The part cleaning agent is good in cleaning effect and low in cost.

Description

technical field [0001] The invention relates to a part cleaning agent. Background technique [0002] At present, the metal pretreatment technology at home and abroad usually adopts alkaline degreasing, including chemical alkali cleaning and electrolytic alkaline cleaning, and then neutralizes the alkaline residue with a weak acid solution, and then cleans the metal structural parts. Rinse, and finally put the metal structural parts into the pickling tank for pickling and derusting. In the pickling process, due to the strong volatility of the pickling liquid, even if the production environment is ventilated by opening windows and using a strong exhaust device, the effect is very small. A large amount of acid mist is volatilized, which seriously affects the safety of other equipment in the workshop. The service life increases the cost of equipment maintenance, which greatly increases the cost. Contents of the invention [0003] The object of the present invention is to pro...
