生产要素组合

To decrease maufacture costs and improve the ratio of efficiency and outlay.The not exensive emulsifier, hydrophobe and other adminicle were mixed with self-made polyesters, siloxane-polyester copolymers to obtain defoamers which be better than imported.And the factors in the process of compound were studied particularly and systemically.the prime project is as follows:the siloxane-polyester copolymer is synthesized with PPG2000,PEG400,1% hydrogen-containing Polyhydrosiloxanes, hexane diacid,which mol ratio of materials is 7:3:6:5.emulsifying agents are SP-60 and tw-60,the value of HLB is 8.5.its dosage is 5%.the concentration of control- bubble resin is 5%. the concentration of liquid hydrocarbon A is 20%.

为进一步降低消泡剂的生产成本，提高其使用时的效费比，采用价格低廉的乳化剂、疏水剂及其他助剂与所制聚醚酯、有机硅改性聚醚酯进行复配，制取了性能优于进口产品的优质消泡剂；并对复配工艺各要素进行了详细、系统的研究；最佳配方为：PPG2000、PEG400、含氢量1%的硅油，己二酸以物质的量之比为7：3：6：5制成的有机硅改性聚醚酯，乳化剂选择SP-60/TW-60组合、HLB值为8.5、用量5%，抑泡树脂用量5%，液态烃A用量20%，液态烃B用量10%，疏水剂用量15%～20%。
