Abstract
The invention discloses a rust removing/inhibiting agent which proportionally comprises hydrochloric acid, surfactant, acid/alkali regulator, a complexing agent and deionized water, which the surfactant is fatty alcohol polyethenoxy ether; the acid/alkali regulator is aminoethanesulfonic acid or sodium hydroxide; and the complexing agent is hexanediamine tetraacetic acid disodium. The rust removing/inhibiting agent disclosed by the invention is reasonable in formula, has favorable rust inhibiting/removing property, can not damage zinc coatings of steel plates, contains environment-friendly solvent and causes less pollution.
Description
Technical field
The invention belongs to surface of steel plate chemical rust removing processing technology field, be specifically related to a kind of rust remover.
Background technology
There are zinc coating or other protective layer in surface of steel plate surface when producing; to prevent got rusty by air corrosion; steel plate often needs cutting in routine use; the cut place gets rusty easily; need timely processing of rust removing, but the strong acid of present rust remover there is very strong corrodibility to destroy the provide protection of zinc coating to zinc coating.
Summary of the invention
The object of the present invention is to provide a kind of formula reasonable, have antirust and rust cleaning performance preferably, do not damage the rust-removing and-preventing agent of steel plate zinc coating.
Technical solution of the present invention is:
A kind of rust-removing and-preventing agent is characterized in that: namely by hydrochloric acid, and tensio-active agent, acid-base modifier, complexing agent, deionized water forms in proportion.
Described tensio-active agent is fatty alcohol-polyoxyethylene ether, and described acid-base modifier is taurine or sodium hydroxide.Described complexing agent is edetate disodium.
The present invention fills a prescription rationally, and is antirust good with the rust cleaning performance, do not damage the steel plate zinc coating, and the solvent environmental pollution is little.
Embodiment:
