[0024] Example 1
[0025] A defoaming agent for sewage treatment. The raw materials in parts by weight include: 10 parts of modified silicone polyether, 20 parts of polyether modified siloxane, 20 parts of emulsifier, 5 parts of polyethylene glycol, and diethanol 0.6 parts of glycerolipid, 0.6 parts of ethylene bisstearamide, 3 parts of heavy liquid paraffin, 10 parts of dimethyl silicone oil, 1 part of white carbon black, 20 parts of complex fatty acid salt, 30 parts of structurant, polypropylene glycol stearin 5 parts of acid fat, 2 parts of dispersant, 3 parts of stabilizer.
[0026] The specific steps of the preparation method of the defoamer for sewage treatment are as follows:
[0027] (1) Weigh all raw materials in parts by weight;
[0028] (2) According to the requirements of the bulk product for toughness, hardness, wear resistance, solubility, and temperature adaptability, put the determined fatty acid species and ratio into the reactor, stir and heat up, when the temperatu...
