Embodiment 1

[0044] A cleaning agent for stainless steel and iron composite plates, the components and respective weight percentages are: fatty alcohol polyoxyethylene ether 15%;

[0045] Alkylphenol polyoxyethylene ether 2%;

[0046] Tartaric acid 6%;

[0047] Corrosion inhibitor 10%;

[0048] Hexamethylenetetramine 10%;

[0049] Metal complexing agent 5%;

[0050] Hydrochloric acid 1%;

[0051] Hydrofluoric acid 1%;

[0052] Sodium molybdate 2%;

[0053] Water 48%.

[0054] When using this descaling agent to descaling the stainless steel and iron composite board, you only need to immerse the plate to be descaled in the descaling agent for cleaning. After the descaling reaction reaches the required level, take it out for rinsing and drying. That's it.

[0055] The present invention can be added repeatedly without additional dosage, is safe and non-toxic, has no pungent odor, and is harmless in contact with skin, and can ensure the occupational health of operators.

Embodiment 2

[0057] A cleaning agent for stainless steel and iron composite plates, the components and respective weight percentages: fatty alcohol polyoxyethylene ether 11%;

[0060] Corrosion inhibitor 11%;

[0061] Hexamethylenetetramine 11%;

[0062] Metal complexing agent 8%;

[0063] Hydrochloric acid 2%;

[0064] Hydrofluoric acid 2%;

[0065] Sodium molybdate 1%;

[0066] Water 44%.

[0067] When using this descaling agent to descaling the stainless steel and iron composite board, you only need to immerse the plate to be descaled in the descaling agent for cleaning. After the descaling reaction reaches the required level, take it out for rinsing and drying. That's it.

Embodiment 3

[0069] A cleaning agent for stainless steel and iron composite plates, the components and respective weight percentages are: fatty alcohol polyoxyethylene ether 17%;

[0070] Alkylphenol polyoxyethylene ether 0.5%;

[0071] Tartaric acid 3%;

[0072] Corrosion inhibitor 13%;

[0073] Hexamethylenetetramine 7%;

[0074] Metal complexing agent 2%;

[0075] Hydrochloric acid 1%;

[0076] Hydrofluoric acid 2%;

[0077] Sodium molybdate 2%;

[0078] Water 52.5%.

[0079] When using this descaling agent to descaling the stainless steel and iron composite board, you only need to immerse the plate to be descaled in the descaling agent for cleaning. After the descaling reaction reaches the required level, take it out for rinsing and drying. That's it.

Abstract

The invention relates to a cleaning operating solution for stainless steel and iron member composite boards. The cleaning operating solution comprises following components by weight: 11%-17% of a polyoxyethylene alkyl ether, 0.5%-3% of an alkylphenol ethoxylate, 3%-7% of tartaric acid, 8%-13% of a corrosion inhibitor, 7%-13% of hexamethylenetetramine, 2%-8% of a metal complexing agent, 1%-2% of hydrochloric acid, 1%-3% of hydrofluoric acid, 1%-2% of sodium molybdate and 40%-60% of water. The cleaning operating solution is simple and safe to use, and is capable of achieving oil removal, rust removal, sinter removal, oxide-scale removal and dirt removal all at once. The cleaning operating solution has no harm to human bodies or pollution to the environment. The cleaning operating solution can be repeatedly used and added without the need of being heated, is free from irritating smells or harm when contacting skin, thus guaranteeing occupation health of operating workers. The cleaning operating solution is low-carbon, cost-saving and environmental-friendly.

Description

Technical field [0001] The invention relates to the field of cleaning agents, in particular to a cleaning working fluid for stainless steel and iron composite plates. Background technique [0002] The cleaning of stainless steel and iron composite plates is a problem that has long plagued practitioners. At present, acid and alkaline cleaning agents are still used to clean stainless steel plates and iron plates in most industrial production. A lot of corrosive liquids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, and hydrofluoric acid are often used in pickling, which will not only volatilize during use, but also produce irritating gas, which will cause great damage to the operator, and even a little carelessness may cause it. Work-related accidents, and after a period of use, the treatment of waste acid solution also causes great pollution to the environment and increases treatment costs for enterprises. [0003] The lye treatment method in the traditiona...
