專業的消泡劑解決方案廠家

消泡劑近些年來以改性(xing)(xing)(xing)聚(ju)(ju)醚(mi)(mi)作為活性(xing)(xing)(xing)成(cheng)分(fen)的(de)有(you)(you)機(ji)硅(gui)(gui)(gui)(gui)消泡(pao)(pao)劑以其優(you)良(liang)的(de)性(xing)(xing)(xing)能在農藥領(ling)域中(zhong)(zhong)脫(tuo)穎而出(chu)，越來越受到(dao)人(ren)們(men)的(de)歡迎。聚(ju)(ju)醚(mi)(mi)改性(xing)(xing)(xing)有(you)(you)機(ji)硅(gui)(gui)(gui)(gui)是(shi)在硅(gui)(gui)(gui)(gui)氧烷(wan)(wan)分(fen)子中(zhong)(zhong)通(tong)過Si-C鍵(jian)銜接和Si-O-C鍵(jian)銜接引入聚(ju)(ju)醚(mi)(mi)鏈(lian)段制得(de)的(de)聚(ju)(ju)醚(mi)(mi)一(yi)硅(gui)(gui)(gui)(gui)氧烷(wan)(wan)共(gong)聚(ju)(ju)物(簡稱硅(gui)(gui)(gui)(gui)醚(mi)(mi)共(gong)聚(ju)(ju)物)，有(you)(you)側(ce)鏈(lian)改性(xing)(xing)(xing)和末(mo)端(duan)改性(xing)(xing)(xing)2種，活性(xing)(xing)(xing)成(cheng)分(fen)是(shi)具有(you)(you)較(jiao)強抑泡(pao)(pao)能力的(de)聚(ju)(ju)醚(mi)(mi)和疏(shu)水性(xing)(xing)(xing)強、破泡(pao)(pao)迅速的(de)二甲基(ji)(ji)硅(gui)(gui)(gui)(gui)油。硅(gui)(gui)(gui)(gui)醚(mi)(mi)共(gong)聚(ju)(ju)物的(de)分(fen)子中(zhong)(zhong).硅(gui)(gui)(gui)(gui)氧烷(wan)(wan)段是(shi)親(qin)油基(ji)(ji)。而親(qin)水基(ji)(ji)是(shi)聚(ju)(ju)醚(mi)(mi)段，聚(ju)(ju)醚(mi)(mi)鏈(lian)段中(zhong)(zhong)聚(ju)(ju)環氧乙烷(wan)(wan)鏈(lian)節能提(ti)供(gong)(gong)親(qin)水性(xing)(xing)(xing)和起泡(pao)(pao)性(xing)(xing)(xing)，聚(ju)(ju)環氧丙烷(wan)(wan)鏈(lian)節提(ti)供(gong)(gong)疏(shu)水性(xing)(xing)(xing)和滲(shen)透力，對表面張力有(you)(you)較(jiao)強的(de)作用。聚(ju)(ju)醚(mi)(mi)鏈(lian)端(duan)的(de)基(ji)(ji)團對硅(gui)(gui)(gui)(gui)醚(mi)(mi)共(gong)聚(ju)(ju)物的(de)性(xing)(xing)(xing)能有(you)(you)很(hen)大的(de)影響，常見的(de)端(duan)基(ji)(ji)有(you)(you)羥基(ji)(ji)、烷(wan)(wan)氧基(ji)(ji)等。
