Embodiment 1
[0084] A wax removal water, consisting of the following components by weight: 6 kg of oleic acid, 3 kg of glycolic acid, 3 kg of citric acid, 0.3 kg of sodium gluconate, 0.6 kg of sodium hydroxide, 5.5 kg of sodium acetate, and 25.5 kg of nonionic surfactant , 2 kg of glyceryl monostearate, 4 kg of isohexanediol and 47.4 kg of water. Among them, the nonionic surfactant consists of 6kg of fatty alcohol polyoxyethylene ether, 3kg of 2-propylheptyl alcohol ethoxylate, 4.5kg of acetylenic glycol ethoxylate and 12kg of isomeric alcohol polyoxyethylene ether composition. In addition, it should be noted that the number of polyoxyethylene in the fatty alcohol polyoxyethylene ether in this embodiment is 15.
[0085] That is, the dewax water of the present embodiment comprises 6% of oleic acid, 3% of glycolic acid, 3% of citric acid, 0.3% of sodium gluconate, 0.6% of sodium hydroxide, 5.5% of sodium acetate, fatty alcohol polyoxygen Vinyl Ether 6%, 2-Propylheptanol Ethoxylate 3%, Alky...
Embodiment 2
[0092] A kind of wax-removing water, its composition ratio is specifically shown in Table 1. The number of polyoxyethylene in the fatty alcohol polyoxyethylene ether in this embodiment is 10.
[0093] The preparation method of dewaxing water is as follows:
[0094] S1: In parts by weight, sodium hydroxide, oleic acid, and glycerol monostearate are stirred and mixed for the first time to obtain a first mixed liquid. The temperature of the reaction kettle was kept at 100° C., the stirring time was 20 minutes, and the stirring speed was 500 r / min.
[0095] S2: After the first mixed liquid is cooled to normal temperature, add fatty alcohol polyoxyethylene ether, 2-propylheptyl alcohol ethoxylate, acetylenic glycol ethoxylate, isomeric alcohol polyoxyethylene ether, isohexanediol Add the first mixed solution to obtain the second mixed solution.
[0096] S3: Completely dissolve citric acid, sodium gluconate, sodium acetate and glycolic acid in water to obtain a third mixed soluti...
Embodiment 3-6
[0099] A wax removal water, the difference from Example 1 is that the amount of each component of the wax removal water is different, see Table 1 for details. The rest are the same as those in Implementation 1, and will not be repeated here.
[0100] Each group distribution ratio of table 1 embodiment 1-6
