專業的消泡劑解決方案廠家

消泡劑近些年來以改(gai)性(xing)(xing)(xing)(xing)聚(ju)(ju)(ju)醚(mi)(mi)(mi)作為活(huo)性(xing)(xing)(xing)(xing)成(cheng)分(fen)(fen)的(de)(de)(de)有(you)(you)機(ji)硅(gui)消泡劑以其優(you)良的(de)(de)(de)性(xing)(xing)(xing)(xing)能(neng)(neng)在農(nong)藥(yao)領域中(zhong)(zhong)脫穎而出，越(yue)來越(yue)受(shou)到人們的(de)(de)(de)歡迎。聚(ju)(ju)(ju)醚(mi)(mi)(mi)改(gai)性(xing)(xing)(xing)(xing)有(you)(you)機(ji)硅(gui)是(shi)在硅(gui)氧烷分(fen)(fen)子中(zhong)(zhong)通過Si-C鍵銜接(jie)和(he)Si-O-C鍵銜接(jie)引入聚(ju)(ju)(ju)醚(mi)(mi)(mi)鏈(lian)段(duan)(duan)制(zhi)得的(de)(de)(de)聚(ju)(ju)(ju)醚(mi)(mi)(mi)一硅(gui)氧烷共(gong)(gong)聚(ju)(ju)(ju)物(wu)(簡稱硅(gui)醚(mi)(mi)(mi)共(gong)(gong)聚(ju)(ju)(ju)物(wu))，有(you)(you)側鏈(lian)改(gai)性(xing)(xing)(xing)(xing)和(he)末端(duan)(duan)改(gai)性(xing)(xing)(xing)(xing)2種，活(huo)性(xing)(xing)(xing)(xing)成(cheng)分(fen)(fen)是(shi)具有(you)(you)較強抑泡能(neng)(neng)力(li)的(de)(de)(de)聚(ju)(ju)(ju)醚(mi)(mi)(mi)和(he)疏水(shui)(shui)性(xing)(xing)(xing)(xing)強、破泡迅速的(de)(de)(de)二甲基(ji)硅(gui)油。硅(gui)醚(mi)(mi)(mi)共(gong)(gong)聚(ju)(ju)(ju)物(wu)的(de)(de)(de)分(fen)(fen)子中(zhong)(zhong).硅(gui)氧烷段(duan)(duan)是(shi)親油基(ji)。而親水(shui)(shui)基(ji)是(shi)聚(ju)(ju)(ju)醚(mi)(mi)(mi)段(duan)(duan)，聚(ju)(ju)(ju)醚(mi)(mi)(mi)鏈(lian)段(duan)(duan)中(zhong)(zhong)聚(ju)(ju)(ju)環氧乙烷鏈(lian)節能(neng)(neng)提供親水(shui)(shui)性(xing)(xing)(xing)(xing)和(he)起泡性(xing)(xing)(xing)(xing)，聚(ju)(ju)(ju)環氧丙烷鏈(lian)節提供疏水(shui)(shui)性(xing)(xing)(xing)(xing)和(he)滲透力(li)，對(dui)表面張力(li)有(you)(you)較強的(de)(de)(de)作用。聚(ju)(ju)(ju)醚(mi)(mi)(mi)鏈(lian)端(duan)(duan)的(de)(de)(de)基(ji)團對(dui)硅(gui)醚(mi)(mi)(mi)共(gong)(gong)聚(ju)(ju)(ju)物(wu)的(de)(de)(de)性(xing)(xing)(xing)(xing)能(neng)(neng)有(you)(you)很大的(de)(de)(de)影響，常見的(de)(de)(de)端(duan)(duan)基(ji)有(you)(you)羥基(ji)、烷氧基(ji)等。
