Abstract

The invention discloses a metal rust remover. The metal rust remover consists of the following components in percentage by weight: 10-30 parts of acetic acid, 2-10 parts of trisodium phosphate, 10-30 parts of ethylene diamine tetraacetic acid, 50-100 parts of citric acid, 5-50 parts of lauryl sodium sulfate and the balance of de-ionized water. The metal rust remover is reasonable in formula, good in rust removal effect and high in rust removal efficiency; and the metal rust remover can rapidly remove oil stain and rust from the surface of metal, and is free from corrosion to the metal.

Description

technical field [0001] The invention relates to the technical field of a rust remover, in particular to a metal rust remover. Background technique [0002] Steel is an indispensable material in modern life and is widely used in industrial and agricultural production and people's lives. However, the metal surface is easily corroded and rusted by the atmosphere and other factors. There are many rust removers on the market now, many of which are prone to produce substances that pollute the environment, have low rust removal efficiency, and are harmful to the human body. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to propose a kind of nontoxic, environment-friendly metal rust remover for the deficiencies in the prior art. [0004] The technical solution adopted in the present invention: a metal rust remover, characterized in that its formula includes the following components according to weight percentage: 10-30 parts of aceti...
