Cleaning agent of grease stain on metallic surface and method of use thereof

Abstract

The invention discloses metal surface oil sludge detergent and a use method thereof; the prescription of the detergent comprises: 0.5 percent to 1 percent of NaOH, 1 percent to 5 percent of Na3PO4, 1 percent to 5 percent of Na2CO3, 0.1 percent to 1 percent of alkylphenol polyvinylether, 0.01 percent to 0.1 percent of silicone antifoam agent, 0.1 percent to 1 percent of fatty alcohol polyethenoxy ether, and the rest is water; the preparation method is as follows: detergent solution is prepared by the weight percent; the use method of the detergent of the invention is to keep the detergent temperature to be 30 DEG C to 80 DEG C when cleaning the oil sludge on the metal surface with the detergent. The detergent of the invention is applicable in cleaning the oil sludge of a plurality of types of metal and alloys, and is characterized by strong cleaning capability, high cleaning speed, low foam, easy rinsing, no corrosion to the metal surface and low consumption.

Description

technical field [0001] The invention relates to a chemical cleaning agent, in particular to a cleaning agent specially used for removing greasy dirt on the metal surface and its application method. Background technique [0002] At present, the chemical cleaning agent used to remove grease on the metal surface is usually a water-based cleaning agent. It is necessary to make the cleaning agent improve the cleaning efficiency of the metal surface grease, and at the same time have good physical and chemical properties and process performance, that is, stability, low foaming, anti-corrosion It is impossible to use one kind of monomer, which can only be achieved by compounding multiple monomers. For example, the Chinese patent "water-based greasy dirt cleaning agent" whose publication number is CN101003769 has a formula of: oleic acid: 2-10%, ethanolamines: 10-20%, surfactant: 10-20%, sodium metasilicate: 5-10%, sodium carbonate: 5-10%, sodium fluorosilicate: 2-4%, defoamer: 0.05...
