Abstract

The invention relates to a cleaning agent for galvanized metal parts. The cleaning agent comprises the following components by weight: 12%-18% of fatty alcohol polyoxyethylene ether, 4%-8% of alkylphenol polyoxyethylene, 1%-5% of tartaric acid, 14%-20% of oxalic acid, 2%-4% of citric acid, 7%-13% of a corrosion inhibitor and 45%-55% of water. The cleaning agent provided by the invention does not require heating for cleaning the galvanized metal parts, can be used repeatedly at room temperature and does not cause irritating smell, so as to reduce emissions; and the cleaning agent does not to hurt the environment, equipment or occupational health of operation personnel, and is green and environment-friendly.

Description

A kind of metal galvanized workpiece environment-friendly cleaning agent

Technical field

The present invention relates to cleaner for metal field, be specifically related to a kind of metal galvanized workpiece clean-out system.

Background technology

In existing zinc-plated industry, cleaning process is all roughly to carry out soak degreasing oil removing with strong acid, highly basic, then high pressure water washing, whole cleaning process is used a large amount of strong acid example hydrochloric acids, sulfuric acid, hydrofluoric acid, and these strong acid also will be through heating to 65 ℃, make workplace be full of acid mist, smell is pungent, and operator's health is caused to very big infringement; Sour gas also can corrode factory house, equipment, pipeline; Spent acid can bring very large harm to surrounding environment.

Summary of the invention

The object of this invention is to provide a kind of metal galvanized workpiece environment-friendly cleaning agent, it can use at normal temperatures without heating, and has no irritating odor, and can repeatedly add Reusability, can to environment, equipment, operator's Occupational health, not bring injury, environmental protection.

For achieving the above object, technical scheme of the present invention is: a kind of metal galvanized workpiece environment-friendly cleaning agent, and the component of described metal galvanized workpiece environment-friendly cleaning agent and separately weight percent are:

Fatty alcohol-polyoxyethylene ether 12%～18%;

Alkylphenol polyoxyethylene 4%～8%;

Tartrate 1%～5%;

Oxalic acid 14% ~ 20%;

Citric acid 2%～4%;

Inhibiter 7%～13%;

Water 45%～55%.

Preferably, the component of described metal galvanized workpiece environment-friendly cleaning agent and separately weight percent be:

Fatty alcohol-polyoxyethylene ether 14%～16%;

Alkylphenol polyoxyethylene 5%～7%;

Tartrate 2%～4%;

Oxalic acid 15% ~ 18%;

Citric acid 2%～4%;

Inhibiter 9%～11%;

Water 45%～55%.

Fatty alcohol-polyoxyethylene ether 15%;

Alkylphenol polyoxyethylene 5%;

Tartrate 2%;

Oxalic acid 16%;

Citric acid 3%;

Inhibiter 10%;

Water 49%.

Preferably, described fatty alcohol-polyoxyethylene ether is JFC penetrating fluid.

Preferably, described alkylphenol polyoxyethylene is emulsion OP-10.

Preferably, described inhibiter is a kind of in thionamic acid inhibiter, citric acid inhibiter, nitric acid inhibiter, salt acid inhibitor, sulfuric acid inhibiter, the multiplex inhibiter of Lan-826, or several mixtures wherein.

When the present invention cleans metal galvanized workpiece, without heating, can use at normal temperatures, have no irritating odor, can repeatedly add Reusability, reduce discharge, can to environment, equipment, operator's Occupational health, not bring injury, environmental protection.

Embodiment

Below in conjunction with specific embodiment, technical scheme of the present invention is further described, but the present invention is not limited to these embodiment.
