Chifukwa chiyani timawonjezera CPE kuzinthu za PVC?

PVC Polyvinyl Chloride ndi utomoni wa thermoplastic wopangidwa kuchokera ku chlorinated Polyethylene pansi pa zochita za woyambitsa. Ndi homopolymer ya Vinyl Chloride. PVC chimagwiritsidwa ntchito zomangira, mankhwala mafakitale, zofunika tsiku ndi tsiku, zikopa pansi, matailosi pansi, Chikopa yokumba, mipope, mawaya ndi zingwe, ma CD mafilimu, mabotolo, thovu zipangizo, kusindikiza zipangizo, ulusi, etc.
Ubwino wodziwika bwino wazinthu zamapulasitiki a PVC ndi kuchedwa kwa lawi, kukana kuvala, kukana kwa dzimbiri, komanso kutsika kwa mpweya ndi nthunzi yamadzi. Kuphatikiza apo, mphamvu zamakina, zinthu zowonekera, kutsekereza magetsi, kutchinjiriza kutentha, kuchepetsa phokoso, komanso kuyamwitsa kunjenjemera ndizabwino, zomwe zimapangitsa kuti ikhale yotsika mtengo kwambiri padziko lonse lapansi. Komabe, zovuta zake ndizosakhazikika kwamafuta komanso kukana kwamphamvu, zomwe zimatha kuyambitsa kufooka mukamagwiritsa ntchito PVC yolimba komanso yofewa. Chifukwa PVC ndi pulasitiki yolimba, kuti ikhale yofewa ndikuwongolera kukana kwake, pulasitiki yochulukirapo iyenera kuwonjezeredwa.
CPE klorini polyethylene ndi zabwino toughening wothandizira kwa PVC. Makamaka 135a mtundu wa CPE Chlorinated Polyethylene ili ndi kukana kwambiri kutentha kwapang'onopang'ono, motero imagwiritsidwa ntchito kwambiri ngati chosinthira pazinthu zolimba za PVC. Mlingo wa 135a mtundu wa CPE womwe umagwiritsidwa ntchito ngati chosinthira pa mbiri ya PVC ndi magawo 9-12, ndipo mlingo wa magawo 4-6 omwe amagwiritsidwa ntchito ngati chosinthira mipope yamadzi ya PVC kapena mapaipi ena opanikizidwa amadzimadzi, kuwongolera bwino kutentha. kukana kwa zinthu za PVC. Nthawi zambiri, kuwonjezera chlorinated Polyethylene ku zinthu za PVC nthawi zambiri kumakhala ndi zotsatirazi: kukulitsa kulimba kwa chinthu, kuwongolera kukana, ndikusintha mphamvu ya chinthucho.
Kuphatikiza apo, CPE 135A Chlorinated Polyethylene imawonjezedwa kwambiri ku mapepala a PVC, mapepala, mabokosi apulasitiki a calcium, zipolopolo zanyumba, ndi zipangizo zamagetsi kuti apititse patsogolo mphamvu zakuthupi, zamakina, ndi zamagetsi za PVC.
