Zotsatira za CPE Addition pa PVC

1, Zinthu zitatu zazikulu zomwe zimakhudza magwiridwe antchito a CPE
Choyamba, ndi mtundu wa CPE ntchito. CPE analandira mkulu maselo kulemera polyethylene ali mkulu mamasukidwe akayendedwe ndi kumakoka mphamvu, koma adhesion pakati CPE ndi PVC utomoni ndi otsika. CPE yopezedwa kuchokera ku polyethylene yotsika kwambiri yama cell imakhala ndi kukhuthala kochepa komanso mphamvu zamakokedwe, ndipo CPE yochokera ku polyethylene yolimba kwambiri imakhala ndi kukana bwino kwa kutentha.
Kachiwiri, ndi kukula kwa zopangira particles. Pamene tinthu tating'onoting'ono tating'ono, zimakhala zosavuta kupanga odzola kapena Clumpy CPE, ndipo pamene tinthu tating'onoting'ono tating'onoting'ono, kugawidwa kwa chlorine kumakhala kosiyana.
Apanso, ndi mlingo wa CPE chlorination. Pamene klorini ili pansi pa 25%, imakhala yosagwirizana ndi PVC ndipo sichingagwiritsidwe ntchito ngati chosinthira; Pamene klorini zili zazikulu kuposa 40%, zimakhala zogwirizana bwino ndi PVC ndipo zingagwiritsidwe ntchito ngati pulasitiki yolimba, osati yoyenera ngati chosinthira; CPE ndi chlorine zili 36-38% ali elasticity wabwino ndi ngakhale ndi PVC, kupanga izo ankagwiritsa ntchito monga zosintha mmene PVC. Pakadali pano, CPE yokhala ndi chlorine ya 35% imagwiritsidwa ntchito kwambiri. CPE ndi chlorine zili mozungulira 35% ali otsika crystallinity ndi galasi kusintha kutentha, elasticity mphira wabwino, ndi ngakhale oyenera ndi PVC. Amagwiritsidwa ntchito kwambiri ngati chosinthira chosinthira pazinthu zolimba za PVC.
2, Zotsatira za CPE Kuwonjezera pa PVC
Pamene ndalama zowonjezera zili pansi pa maminiti a 10, mphamvu ya PVC imakula mofulumira ndi kuwonjezera kwa CPE, koma kuonjezera kuwonjezereka kwa CPE kumapangitsa kuti pakhale kusintha pang'ono kwa mphamvu ya PVC. Chifukwa chake, monga chothandizira kugonjetsedwa, kuchuluka koyenera kwa CPE kuwonjezeredwa ndi magawo 8-10. Pamene CPE ikuchulukirachulukira, kulimba kwamphamvu kwamaphatikizidwe a PVC kumapitilirabe kuchepa, pomwe kutalika kwa nthawi yopuma kumawonjezeka. Ngati kulimba kumawonetsedwa ngati mphamvu yolimba komanso kutalika kwanthawi yopuma, zikuwonekeratu kuti kulimba kwa PVC kudzawonjezeka kwambiri pakuwonjezeka kwa CPE.
