When in use, take this product and water and dissolve it according to the ratio of 1: 10, then it can be used to clean metals.
4) Formula 4: New water-based metal cleaning agent.
The mass fraction of each raw material is: AE09 2.6%, triethanolamine oleate 3.5%, na2co 3 4.3%, triethanolamine 7.8%, TX- 10 5%, sodium benzoate 4. 1%, and the rest is water; The content (mass fraction) of each component in Formula 2 is: 4-5% flat plus 0.5-2% triethanolamine oleate, 4.3% na2co 3, 6.5% triethanolamine, 7.2% 650 1.2% sodium gluconate, 3.7% sodium benzoate, and the rest is water. It has the characteristics of stability, high decontamination rate and strong anti-corrosion and anti-rust ability, and is non-toxic and harmless to human body. Especially at room temperature, the cleaning rate can reach above 96%.
5) Formula 5: Low-foaming water-based metal cleaning agent
The mass fraction of each raw material component is 0.5% 6501; 0.5% triethanolamine oleic acid soap; 0.25% GT- 12； 0.25% s-86; 1.25% M- 10； 0.75% polyether l 61; 10% triethanolamine; 1% na2co 3； 1% borax; 5% disodium EDTA; 0.3% silica gel
6) Formula 6: Environmental-friendly industrial water-based metal cleaning agent
The mass fraction of each raw material component is: the dosage of fatty alcohol polyoxyethylene ether 10%, lauric diethanolamide 6%, amyloside surfactant 7%, polyoxyethylene ether sulfate 2.2%, dioctyl sulfosuccinate sodium 1.8%, sodium benzoate 1%, and water glass 0.1. A nonionic surfactant and an anionic surfactant are compounded, a certain amount of deionized water is added into a beaker of 100 mL, stirred at high speed, and the temperature is controlled at about 55℃, then fatty alcohol polyoxyethylene ether is added in turn, and starch glycoside surfactant is added after complete dissolution, and then stirring is continued, and lauric diethanolamide is added in turn after 30 minutes. Polyoxyethylene ether sulfate and urea (the temperature and concentration of polyoxyethylene ether sulfate should be accurately controlled during preparation to prevent the polyoxyethylene ether sulfate from forming gel), continue to stir for 30 ~ 45 minutes, cool to about 40℃, add sodium di-sec-octyl sulfosuccinate, preservative and other additives, continue to stir for a few minutes, and cool to room temperature.
