目的性選擇助劑

不(bu)同類型的(de)(de)(de)助劑(ji)具(ju)有不(bu)同的(de)(de)(de)目標(biao)(biao)性能(neng)，所(suo)加入體系(xi)中(zhong)的(de)(de)(de)助劑(ji)能(neng)夠充分其(qi)預計功能(neng)，并達到目標(biao)(biao)規(gui)定指標(biao)(biao)。其(qi)中(zhong)，規(gui)定指標(biao)(biao)一般為國(guo)家標(biao)(biao)準、國(guo)際標(biao)(biao)準，或客戶提(ti)出的(de)(de)(de)性能(neng)要求。常見的(de)(de)(de)目標(biao)(biao)樹脂改性的(de)(de)(de)性能(neng)如(ru)下(xia)：
