Example Embodiment

[0041] Example 1

[0042] A cold-rolled sheet descaling agent, its components and their respective weight percentages are:

[0043] JFC penetrant 10%;

[0044] Emulsifier OP-10 10%;

[0045] Hexamethylenetetramine 7%;

[0046] EDTA 6%;

[0047] Citric acid 2%;

[0048] Oxalic acid 10%;

[0049] Thiourea 10%;

[0050] Hydrochloric acid 2%;

[0051] Water 43%.

[0052] After all the ingredients are added, stir for another 20 to 30 minutes to get the finished product.

[0053] When using this cleaning agent to clean the cold-rolled sheet, it is only necessary to immerse the cold-rolled sheet in the cleaning agent for cleaning. After the descaling reaction reaches the required level, take it out for rinsing and drying.

Example Embodiment

[0054] Example 2

[0058] Hexamethylenetetramine 8%;

[0059] HEDTA 7%;

[0060] Citric acid 3%;

[0061] Oxalic acid 9%;

[0062] Sodium nitrite 9%;

[0063] Hydrochloric acid 2.5%;

[0064] Water 41.5%.

[0065] After all the ingredients are added, stir for another 20 to 30 minutes to get the finished product.

Example Embodiment

[0066] Example 3

[0067] A cold-rolled sheet descaling agent, its components and their respective weight percentages are:

[0068] JFC penetrant 9%;

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. [0004] In order to...
