Abstract

The invention relates to a neutralizer / passivator in a metal surface treatment technique, belonging to the technical field of metal surface treatment. The neutralizer / passivator provided by the invention can thoroughly react with deruster residual liquid without scabbing on the metal surface, and has favorable passivation effect. The neutralizer / passivator is prepared from the following components in percentage by mass: 55-65% of glauber salt, 20-30% of sodium pyrophosphate, 5-15% of sodium hydroxide, 1-5% of sodium carbonate, 0.5-1.5% of borax, 0.5-1.5% of sodium metasilicate, 0.5-1.5% of phosphoric acid and 0.1-0.3% of sodium lauryl sulfate.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and more specifically relates to a neutralization passivator in the metal surface treatment process. technical background [0002] The neutralizer belongs to a process product of the anti-corrosion treatment part of the ferrous metal surface in the field of surface engineering. It is specifically aimed at the rust remover with hydrochloric acid as the main body. A process product for reprocessing the rust agent, commonly known as "neutralizer". After the neutralization process, a series of passivation, surface adjustment, phosphating and other treatments are carried out, and finally meet the standards for long-term anti-corrosion treatments such as swimming paint, spraying or electroplating. [0003] Existing neutralizers are basically strong alkaline components such as sodium hydroxide and sodium carbonate. Although acid and alkali are neutralized to form water, the genera...
