Problems solved by technology

When taking various anti-corrosion measures for steel products, degreasing and rust removal are necessary steps. The traditional degreasing and derusting processes are generally carried out step by step. The equipment investment is large, the process is many, the efficiency is low, the processing time is long, and the energy High energy consumption, severe acid mist, and harmful gas erosion for workers, prone to over-corrosion and hydrogen embrittlement of processed workpieces, and seriously affecting the surrounding environment

Abstract

The invention relates to a metal degreasing and rust removing agent, in particular to an environment-friendly type steel degreasing and rust removing agent, which belongs to the technical field of chemical industry. It includes hydrochloric acid, oxalic acid, surfactants, complexing agents, and corrosion inhibitors. The content of hydrochloric acid is the main factor affecting rust removal. The addition of oxalic acid can significantly reduce acid mist. Surfactants have the functions of degreasing and fog suppression. Due to the synergistic effect of each component of the formula, the process has the characteristics of normal temperature, rapidity, high efficiency, and environmental protection.

Description

technical field [0001] The invention relates to a metal degreasing and rust removing agent, in particular to an environment-friendly type steel degreasing and rust removing agent, which belongs to the technical field of chemical industry. Background technique [0002] Steel is an indispensable material in modern social and economic life. It is widely used in industrial and agricultural production and people's life. However, the surface of various steel products is easily corroded and rusted by atmospheric media and other factors. It takes about one year of steel. 20% to 30% of the output. In order to protect steel products and prolong their service life, anti-corrosion treatment must be carried out on their surfaces. When taking various anti-corrosion measures for steel products, degreasing and rust removal are necessary steps. The traditional degreasing and derusting processes are generally carried out step by step. The equipment investment is large, the process is many, t...
