example 1

[0008] Example 1: Prepare 100 kg of cleaning agent, operate at room temperature, and the area of ​​steel that can be cleaned is ≥ 2600m 2 , It can be cleaned in about 20 minutes. When the cleaning temperature is 50°C, it can be cleaned in about 10 minutes.

[0009] Preparation method: take 10 kg of tap water, preparation temperature: 76°C, add phosphoric acid: 15 kg, sodium tartrate: 10 kg, sodium sulfate: 1.5 kg, zinc phosphate: 2 kg, sulfur urine: 1 kg and tributyl phosphate: 1 Dissolve 1 kg for later use; then take 10 kg of tap water, add OP-10: 5 kg, SPAN-80: 3 kg, imidazoline: 6 kg, urotropine: 1 kg, disodium EDTA: 1 kg and ethylene glycol: 3 kg is dissolved for use; then the two reserve solutions are mixed, and tap water is added to 100 kg to complete.

example 2

[0010] Example 2: Prepare 100 kg of cleaning agent, operate at room temperature, and can clean severely rusted steel with an area of ​​≥ 2600m 2 , It can be cleaned in about 20 minutes. When the cleaning temperature is 50°C, it can be cleaned in about 10 minutes.

[0011] Preparation method: take 10 kg of tap water, preparation temperature: 76°C, add phosphoric acid: 26 kg, sodium tartrate: 13.5 kg, sodium sulfate: 3 kg, zinc phosphate: 4 kg, sulfur urine: 2 kg and tributyl phosphate: 1.5 Dissolve 1 kg for later use; then take 10 kg of tap water, add OP-10: 7 kg, SPAN-80: 6 kg, imidazoline: 10 kg, urotropine: 2 kg, disodium EDTA: 1.5 kg and ethylene glycol: Dissolve 4 kg for later use; then mix the two reserve solutions, add tap water to 100 kg and complete.

Abstract

The invention relates to multifunctional metal detergent special for rolled steel which can wash large quantity of rolled steel. Meal detergent uses phosphoric acid, sodium tartrate, sodium sulfate, 0P-10, SPAN-80, imidazoline, zinc phosphate, urotropine, sulfur urine, tributyl phosphate, EDTA disodium and ethylene alcohol as raw material, and compounds with water. The detergent has not only low cost, but also high efficiency, and no acid mist in the working environment, which can not pollute operating environment, the waste liquid is non-pollution and nuisance-free, the operation can be carried out in warming or in normal temperature, technological requirements of flow line process can be met, the invention can be used water which is diluted the detergent, or used by adding with fluid replacement, which greatly reduces use cost, and has safe use, convenience and high efficiency.

Description

technical field [0001] The invention relates to a multi-functional special metal cleaning agent for steel for cleaning large quantities of steel. Background technique [0002] At present, there are many types of acid cleaners on the market with different functions, but they are generally used for degreasing and rust removal, some need to be used under heating, and some are used under normal temperature, but generally they are not special steel products The cleaning agent has high cost and poor efficiency, and some even have acid mist, which will pollute the operating environment and seriously affect the safety and health of operators, and its waste liquid will also cause public nuisance. Contents of the invention [0003] In order to solve the problems existing in the derusting and degreasing of steel, the present invention provides a multi-functional special metal cleaning agent for steel. The cleaning agent is not only low in cost and high in efficiency, but also has no ...
