Kwifilimu enqabileyo ye-PVC, kukulungele ukusebenzisa uhlobo lwe-6 okanye i-resin ye-7, nangona intambo kunye noxhumo lwentambo kunye nefilimu eyanciphayo, i-resistiveivity yomzimba ayikho phezulu njenge-2 okanye i-3 resin, kodwa i-resin 7 yokubumba, imveliso. umkhuba uye wabonisa ukuba ukusetyenziswa 2 okanye 3 resin, kunzima ukwenza, nzima PVC ishwabene imveliso film nzima kwaye brittle, ayinakusongwa kwaye iqengqeleke.
Xa kusetyenziswa i-plasticizer, ukushisa kwe-thermal shrinkage kuncipha ngokunyuka komxholo we-plasticizer.Umzekelo, ukusetyenziswa kokunqumamisa uhlobo lwe-3 PVC umgubo onamafutha womthi, ukongeza i-DOP plasticizer ye-30-50 PHR, inokuba yi-biaxial tensile malunga ne-70 ℃, kwaye iimveliso zayo zinokucutheka malunga ne-40 ℃, ayikwazi ukugcinwa kwiintsuku ezishushu.Ngaphezu koko, ngokunyuka komxholo we-plasticizer, ukuxhathisa komzimba we-sleeve eshwabeneyo ubushushu yocingo kunye nentambo iyehla.Ngoko ke, xa sisebenzisa umkhono wePVC oshwabeneyo wobushushu kwiintambo zocingo kunye neentambo zokudityaniswa kwentambo, sisasebenzisa uhlobo lwe-6 okanye i-7 resins ekulula ukuqhubekeka.Ukuze kuphuculwe ukugquma, sisebenzisa i-stabilizer yokushisa edibeneyo kunye neetyuwa ezintathu kunye neetyuwa ezimbini kunye nokuphucula ngokufanelekileyo ubuninzi befilimu ukuze kuqinisekiswe ukugquma.Irabha ye-nitrile ye-P83 ine-machinability elungileyo, ukuqina, ukumelana nokubanda, kwaye inokuphucula amandla, iphucule ukuxhathisa kokuqhekeka koxinzelelo lweemveliso zePVC.I-Active CaCO3 iphucula ubukhulu becala ukugquma kunye nokuncipha komlilo kweemveliso kwaye inciphisa iindleko.
