01 Phosphorus-free water-basedmetal cleaning agent

The mass fraction of each raw material component is: AESA(C12 fatty alcohol polyoxyethylene ether ammonium sulfate):BJH -1 (fatty amines, self-made):OP-10 (octylphenol polyoxyethylene ether):M550 (halogenated dimethyl dipropyl ammonium propionyl ammonium copolymer) = 6:4:4:1 (molar ratio), and Na-CP4 (sodium salt of maleic anhydride and acrylic acid copolymer) and sodium silicate are added as detergent builders according to the mass ratio of 95, the washing effect and antirust performance of 5% dilution were evaluated. The results show that the cleaning agent has strong decontamination ability and good antirust performance, does not contain phosphide, and is environmentally friendly.

02 metal bearing water-based cleaning agent

The mass fraction of each raw material component is: fatty alcohol polyoxyethylene ether 2% ~ 8%; Alkylphenol polyoxyethylene ether 2% ~ 8%; Fatty acid alkanolamide 3% ~ 10%; Oleic acid triethanolamine 5% ~ 25%; Triethanolamine 10% ~ 22%; Monoethanolamine 5% ~ 18%; Sodium alkyl sulfonate 0.5 ~ 3%; Benzotriazole 0.01~0.5; Sodium ethylenediaminetetraacetic acid 1% ~ 2%; water 3.5-71.49%.

03 A metal cleaning agent
The metal surface cleaning agent is prepared from the following raw materials, the mass fraction of each raw material component is: sodium silicate (35% ~ 45%), sodium tripolyphosphate (50% ~ 55%), fatty alcohol polyoxyethylene ether (5% ~ 10%). When in use, take this product and water according to the ratio of 1:10 to dissolve can be used for cleaning metal.
04 Low-foaming water-based metal cleaner
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 L61;10% triethanolamine; 1% Na2CO3;1% borax; 5% disodium EDTA; 0.3 silicone.

05 environmentally friendly industrial water-based metal cleaning agent

The mass fraction of each raw material component is: fatty alcohol polyoxyethylene ether 10%, lauric acid diethanolamide 6%, starch glycoside surfactant 7%, polyoxyethylene ether sulfate 2.2, sodium salt of dioctyl sulfosuccinate 1.8, sodium benzoate l%, sodium silicate 0.1, urea 1%; Mix with nonionic and anionic surfactants, add a certain amount of deionized water into a 100 mL beaker and stir at high speed, control the temperature at about 55 ℃, add fatty alcohol polyoxyethylene ether in turn, add starch glycoside surfactant after it is completely dissolved, and continue to stir. After 30 min, add lauric acid diethanolamide, polyoxyethylene ether sulfate and urea in turn (the temperature and polyoxyethylene ether sulfate concentration should be accurately controlled during preparation to prevent polyoxyethylene ether sulfate from forming gel), continue to stir for 30~45 rain, cool to about 40 ℃, and add sodium salt of sulfonated dioctyl succinate, preservatives and other additives, continue to stir for a few minutes, can be cooled to room temperature.
