Degreasing and cleaning agent for chemical equipment

Abstract

The invention provides a degreasing and cleaning agent for chemical equipment. The degreasing and cleaning agent comprises the following components in parts by weight: 3.0 to 5.8 parts of aluminum-magnesium silicate, 3.5 to 8.0 parts of arginine, 5.0 to 8.5 parts of docusate sodium, 5.5 to 7.2 parts of tetrasodium EDTA, 6.5 to 9.3 parts of metal ion chelating agent, 1.6 to 2.8 parts of bentonite, and 2.2 to 5.6 parts of sucrose fatty acid ester. The provided degreasing agent is especially suitable for cleaning and degreasing important chemical equipment, such as stainless steel, pipelines, containers, and the like; is noncorrosive to the surface of metal equipment, is barely affected by acid, alkali, soft water, hard water, and seawater; has a strong degreasing performance and good cleaning effect; is nontoxic and flame retardant, and thus has a wide application prospect. After cleaning and degreasing, the surface is lustrous and does not become black, the degreasing and cleaning agent is user-friendly, and the pollution and cleaning cost are reduced.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a degreasing cleaning agent for chemical equipment. Background technique [0002] Metal and its products are often contaminated with various dirt and impurities on the surface during processing or after a period of use, so cleaning is an extremely important part of metal surface treatment, especially stainless steel materials, pipelines, and containers. For important chemical equipment, cleaning has become a very necessary process. Cleaning generally requires degreasing first, then pickling and passivation. The purpose of degreasing is to remove the grease produced on the metal surface during the process of binding, manufacturing and installation, so that the pickling solution can completely contact the metal surface, so as to ensure the quality of pickling and passivation. Commonly used cleaning and degreasing agents with degreasing as the main purpose generally incl...

Problems solved by technology

But for stainless steel, because the surface of stainless steel itself has a protective film, uranium hydroxide has an erosive effect on the protective film. After degreasing, the surface becomes black, the degreasing is not complete, and the effect is not ideal, so that the quality of the subsequent process cannot be guaranteed

More importantly, the stainless steel degreased by uranium hydroxide is prone to embrittlement after a period of use, resulting in the failure of stainless steel equipment.
