Abstract
The invention relates to an environmental-friendly cleaning liquid for a cold-rolled sheet. The cleaning liquid comprises the following components by weigh: 8%-12% of fatty alcohol polyoxyethylene ether, 8%-12% of alkylphenol polyoxyethylene, 5%-10% of hexamethylenetetramine, 5%-8% of a metal complexing agent, 1%-4% of citric acid, 18%-22% of oxalic acid, 0.5%-1.5% of hydrochloric acid and 40%-50% of water. When used, the cleaning liquid provided by the invention does not require heating, generates no smell or damage to the staff, and can be used repeatedly to realize extremely little discharge, green and environmental protection.
Description
Technical field
The present invention relates to cleaner for metal field, be specifically related to a kind of cold rolled sheet Environment protection cleaning liquid.
Background technology
In existing roll bending industry, cleaning process is roughly as follows: sodium hydroxide, sodium carbonate are warmed to 90 ℃ ~ 95 ℃ and carry out degreasing degreasing, then roll bending is gone out to groove tow sides high pressure water washing, enter afterwards pickling in 70 ℃ of left and right acid tanks and fall oxide skin and dirt, finally shower is cleaned again.Whole cleaning, through alkali cleaning, pickling under high temperature, is used a large amount of strong acid and strong bases, and in operation room, smell is pungent, full of smoke, to operator's respiratory system with healthyly bring very big infringement.Spent acid salkali waste after use forms a large amount of industrial effluent, increases processing cost, contaminate environment.
