AI Technical Summary

Problems solved by technology

All of the above surfactants have good emulsification and degreasing properties, but the dispersion performance is generally poor
Domestic metal cleaning agents are often obtained by compounding the above surfactants, so the common problems are that the foam is too high, the dispersion performance is poor, the oil stains are easy to contaminate the metal surface, and the degreasing speed is slow, and the low temperature condition Lower cleaning effect is worse

The environment-friendly powerful deoiling rust-removal cleaning agent is prepared from the following components in percentage by weight: 20-50% of fatty acid methyl ester ethoxylate sulfonate, 1-6% of potassium pyrophosphate, 1-8% of EDTA2Na, 2-5% of potassium hydroxide, 2-6 parts of sodium silicate, 1-5 parts of sodium silicate SiO2:Na2O, and the balance of water. The preparation method disclosed by the invention is simple and easy to operate, safe and environment-friendly; the prepared product is small in foam, high in dispersion force, high in anti-fouling property, easy to clean, safe, environment-friendly, and free of harmfulness to body health of an operator.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly strong oil-removing and rust-removing cleaning agent, which belongs to the field of industrial cleaning. Background technique [0002] In industrial production, whether it is the processing and assembly of parts, or heat treatment, electroplating, and product packaging and unsealing, the metal surface must be cleaned; large machinery such as vehicles and ships are prone to oil and dust, in order to improve coating adhesion and durability Corrosion, the metal surface must be degreased and degreased before painting. The dirt attached to the metal surface includes various acids, alkalis, salts, dust, cutting, hand sweat, oil stains, etc. The existence of these dirts not only affects the smooth progress of metal electroplating, coating and other processing procedures, but also causes And accelerate metal corrosion, reduce product quality and shorten service life. Cleaning oil and ru...
