Cold-rolled sheet detergent

Abstract

The invention relates to a cold-rolled sheet detergent. The detergent comprises 8-12wt% of fatty alcohol polyoxyethylene ether, 8-12wt% of alkylphenol polyoxyethylene, 5-10wt% of hexamethylenetetramine, 5-8wt% of a metal complexing agent, 1-4wt% of citric acid, 9-12wt% of oxalic acid, 8-12wt% of a corrosion inhibitor, 1.5-3wt% of hydrochloric acid and 40-50wt% of water. The detergent can well clean a cold rolled sheet, and can simultaneously realize degreasing, cleaning and descaling, so the detergent has the advantages of work simplification, manpower and material resource saving, and work efficiency improvement.

Description

technical field

[0001] The invention relates to the field of metal cleaning agents, in particular to a cold-rolled sheet descaling agent. Background technique

[0002] In the existing coil industry, the cleaning process is roughly as follows: heat sodium hydroxide and sodium carbonate to 90°C~95°C for degreasing and degreasing, then wash the coil plate out of the tank with high-pressure water on both sides, and then enter 70°C Acid wash off the scale and dirt in the left and right acid tanks, and finally rinse and clean. The whole cleaning process has to go through multiple procedures, such as alkali cleaning, pickling, rinsing, etc. The process is tedious, time-consuming and labor-intensive. Contents of the invention

[0003] The purpose of the present invention is to provide a cold-rolled sheet descaling agent, which can solve oil removal, descaling and descaling at one time, simplify production procedures, and save manpower and material resources.
