Nchifukwa chiyani timawonjezera CPE ku zinthu za PVC?

PVC Polyvinyl Chloride ndi utomoni wa thermoplastic womwe umapangidwa ndi Chlorinated Polyethylene pogwiritsa ntchito choyambitsa. Ndi homopolymer ya Vinyl Chloride. PVC imagwiritsidwa ntchito kwambiri pa zipangizo zomangira, zinthu zamafakitale, zofunikira za tsiku ndi tsiku, chikopa cha pansi, matailosi a pansi, chikopa chopangira, mapaipi, mawaya ndi zingwe, mafilimu opaka, mabotolo, zipangizo zotulutsa thovu, zipangizo zotsekera, ulusi, ndi zina zotero.
Ubwino waukulu wa zinthu za pulasitiki za PVC resin ndi kuchedwa kwa moto, kukana kuwonongeka, kukana dzimbiri kwa mankhwala, komanso kutayikira pang'ono kwa mpweya ndi nthunzi ya madzi. Kuphatikiza apo, mphamvu zonse zamakanika, zinthu zowonekera bwino, kutchinjiriza magetsi, kutchinjiriza kutentha, kuchepetsa phokoso, komanso kuyamwa kwa mantha nazonso ndizabwino, zomwe zimapangitsa kuti ikhale chinthu chotsika mtengo kwambiri padziko lonse lapansi. Komabe, zovuta zake ndi kukhazikika kwa kutentha komanso kukana kugunda, zomwe zingayambitse kufooka mosavuta pogwiritsa ntchito PVC yolimba komanso yofewa. Chifukwa PVC ndi pulasitiki yolimba, kuti ikhale yofewa ndikuwonjezera kukana kugunda, pulasitiki wambiri iyenera kuwonjezeredwa.
Polyethylene ya CPE yokhala ndi chlorine ndi chinthu chabwino kwambiri cholimba cha PVC. Polyethylene yapadera ya CPE yokhala ndi chlorine yokhala ndi 135a imakhala ndi mphamvu yotsika kutentha, kotero imagwiritsidwa ntchito makamaka ngati chosinthira mphamvu pazinthu zolimba za PVC. Mlingo wa CPE ya 135a yomwe imagwiritsidwa ntchito ngati chosinthira mphamvu pa ma profiles a PVC ndi magawo 9-12, ndipo mlingo wa magawo 4-6 womwe umagwiritsidwa ntchito ngati chosinthira mphamvu pa mapaipi amadzi a PVC kapena mapaipi ena onyamula madzi opanikizika, zomwe zimapangitsa kuti zinthu za PVC zikhale zolimba kutentha. Kawirikawiri, kuwonjezera Chlorinated Polyethylene ku zinthu za PVC nthawi zambiri kumakhala ndi zotsatirazi: kuwonjezera kulimba kwa chinthucho, kusintha kukana mphamvu, ndi kusintha mphamvu ya chinthucho.
Kuphatikiza apo, CPE 135A Chlorinated Polyethylene imawonjezeredwa kwambiri pamapepala a PVC, mapepala, mabokosi apulasitiki a calcium, zipolopolo za zida zapakhomo, ndi zowonjezera zamagetsi kuti ziwongolere mawonekedwe, makina, ndi magetsi a zinthu za PVC.
