Embodiment 1-4

[0028] Prepare the present invention's degreaser for stainless steel respectively by following formula:

[0029] Table 1 embodiment 1-4 is used for the formula (unit: weight percent) of the degreasing agent of stainless steel

[0030]

[0031] The preparation method of embodiment 1-4 is similar, taking embodiment 3 as example, its preparation method is:

[0032] (1) Add 500L of water to a 1000L reaction stirring tank, then add sodium hydroxide, and stir for 10 minutes;

[0033] (2) Add TX-10 into the reaction stirring tank, and stir with sodium hydroxide aqueous solution for 30 minutes;

[0034] (3) Add OP-10, AEO-9 and dispersant IW in sequence, and stir for 60 minutes;

[0035] (4) Add sodium carbonate and sodium phosphate into the reaction stirring tank, and stir until there is no sediment in the tank;

[0036] (5) Add defoamer FAG470, stir for 30 minutes, then add water to 1000L liquid level.

Embodiment 5

[0038] Take flat 201 stainless steel plate workpieces of the same size, spray and clean them with the degreaser prepared in Examples 1-4 and the commercially available degreaser respectively, and compare the degreasing effect:

Abstract

The invention discloses a production method of an oil removal agent for stainless steel, which comprises the following steps of: (1) fetching the following components in percentage by weight: 4-10% of nonylphenol polyoxyethylene ether, 1-3% of OP-10, 4-10% of fatty alcohol-polyoxyethylene ether, 5-1-% of dispersing agent IW, 10-18% of sodium hydroxide, 1-4% of sodium carbonate, 2-5% of sodium carbonate, 4-8% of antifoaming agent and the balance of water; and adding a proper amount of water into a tank, then adding the sodium hydroxide, and stirring; (2) adding the nonylphenol polyoxyethylene ether into the tank, and stirring for 20-40 minutes; (3) sequentially adding the OP-10, the fatty alcohol-polyoxyethylene ether and the dispersing agent IW, and stirring for 50-80 minutes; (4) adding the sodium carbonate and the sodium phosphate, and stirring until no precipitate exists in the tank; and (5) adding the antifoaming agent, stirring and adding the remaining water. By adopting the production method disclosed by the invention, the produced oil removal agent for stainless steel realizes thorough oil removal and fast cleaning, saves energy and labor and brings great convenience to the production of a factory.

Description

technical field [0001] The invention relates to a production method of a degreasing agent, in particular to a production method of a degreasing agent for stainless steel. Background technique [0002] Stainless steel is widely used because of its excellent corrosion resistance and wear resistance. During the treatment of stainless steel, stainless steel degreasing agents are often used. The degreaser products currently on the market have a slow degreasing speed, and the cleaning is not thorough, for example, the stainless steel drawing oil is not thoroughly removed. If the oil stain on the stainless steel is not cleaned, then the stainless steel workpiece cannot enter the next step of production. For example, the welding will fall off during welding, and the aluminum sheet cannot be composited during brazing, etc. In the case where the degreaser does not remove the oil completely, one way to solve the problem is to manually wipe it again with a cloth. But this will incre...
