Abstract

The invention discloses a process for removing rust on the surface of hardware tools. The process is characterized in that the process is prepared from the following raw materials in parts by weight:7-13 parts of benzoic acid, 40-60 parts of deionized water, 5-17 parts of hydrochloric acid, 3-7 parts of boric acid, 1-3 parts of aluminum sulfate, 6-13 parts of ammonium citrate, 1-3 parts of sodiumdihydrogen phosphate, 1-2 parts of alcohol ether phosphate, and 0.5-0.9 part of an emulsifying agent.

Description

technical field [0001] The invention belongs to the field of hardware derusting, in particular to a surface derusting process of hardware tools. Background technique [0002] The main problem in the storage of metal products in hardware products is anti-corrosion. Metal corrosion is caused by the chemical or electrochemical action of the surrounding medium. According to different media, it can be divided into atmospheric corrosion, soil corrosion, seawater corrosion, bacterial corrosion, etc. Among them, atmospheric corrosion is the most common, because metal products are in contact with the atmosphere no matter in the process of processing, transportation and storage, and there are always conditions for atmospheric corrosion. Customarily, the corrosion or discoloration of metals in the atmosphere due to oxygen, moisture and other polluting impurities is called rusting or rusting. After metal products are rusted, the light ones will affect the appearance quality, and the ...
