Zotsatira za Kuwonjezera kwa CPE pa PVC

1. Zinthu zitatu zazikulu zomwe zimakhudza magwiridwe antchito a CPE
Choyamba, ndi mtundu wa CPE womwe umagwiritsidwa ntchito. CPE yochokera ku polyethylene yolemera kwambiri ya mamolekyulu imakhala ndi kukhuthala kwakukulu komanso mphamvu yokoka, koma kugwirizana pakati pa CPE iyi ndi utomoni wa PVC ndi kochepa. CPE yochokera ku polyethylene yolemera pang'ono ya mamolekyulu imakhala ndi kukhuthala kochepa komanso mphamvu yokoka, ndipo CPE yochokera ku polyethylene yolemera kwambiri imakhala ndi kukana kutentha bwino.
Kachiwiri, ndi kukula kwa tinthu tating'onoting'ono ta zinthu zopangira. Tinthu tating'onoting'ono tikakhala tating'ono kwambiri, zimakhala zosavuta kupanga jelly kapena clumpy CPE, ndipo tinthu tating'onoting'ono tikakhala tating'ono kwambiri, kufalikira kwa chlorine sikufanana.
Apanso, ndi mulingo wa CPE chlorination. Pamene kuchuluka kwa chlorine kuli pansi pa 25%, sikugwirizana bwino ndi PVC ndipo sikungagwiritsidwe ntchito ngati chosinthira; Pamene kuchuluka kwa chlorine kuli koposa 40%, kumakhala kogwirizana bwino ndi PVC ndipo kungagwiritsidwe ntchito ngati pulasitiki wolimba, sikoyenera ngati chosinthira mphamvu; CPE yokhala ndi kuchuluka kwa chlorine ya 36-38% imakhala yolimba komanso yogwirizana bwino ndi PVC, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri ngati chosinthira mphamvu ya PVC. Pakadali pano, CPE yokhala ndi kuchuluka kwa chlorine ya 35% imagwiritsidwa ntchito kwambiri. CPE yokhala ndi kuchuluka kwa chlorine ya pafupifupi 35% imakhala ndi crystallinity yochepa komanso kutentha kwa galasi, kusinthasintha kwabwino kwa rabara, komanso kugwirizana koyenera ndi PVC. Imagwiritsidwa ntchito kwambiri ngati chosinthira mphamvu ya zinthu zolimba za PVC.
2, Zotsatira za Kuwonjezera kwa CPE pa PVC
Pamene kuchuluka kwa zowonjezera kuli pansi pa mphindi 10, mphamvu ya PVC imawonjezeka mofulumira ndi kuwonjezera kwa CPE, koma kuwonjezera kuchuluka kwa CPE kumapangitsa kuti mphamvu ya PVC imawonjezeke pang'ono. Chifukwa chake, monga chothandizira cholimbana ndi kugwedezeka, kuchuluka koyenera kwa CPE koti kuonjezedwe ndi magawo 8-10. Pamene CPE ikuwonjezeka, mphamvu ya PVC yosakanikirana ikupitirira kuchepa, pomwe kutalika pakusweka kumawonjezeka. Ngati kulimba kukuwonetsedwa ngati zotsatira za mphamvu ya PVC ndi kutalika pakusweka, n'zoonekeratu kuti kulimba kwa PVC kudzawonjezeka kwambiri ndi kuwonjezeka kwa CPE.
