I-PVC izwela kakhulu ekushiseni.Lapho izinga lokushisa lifinyelela ku-90 ℃, ukusabela kokubola okushisayo okuncane kuqala.Lapho izinga lokushisa likhuphukela ku-120 ℃, ukusabela kokubola kuyaqina.Ngemva kokushisa ku-150 ℃ imizuzu engu-10, inhlaka ye-PVC ishintsha kancane kancane isuka kumbala wayo wasekuqaleni omhlophe iye kophuzi, obomvu, onsundu, nomnyama.Izinga lokushisa lokucubungula le-PVC ukuze lifinyelele isimo sokugeleza kwe-viscous lidinga ukuba libe phezulu kunaleli zinga lokushisa.Ngakho-ke, ukuze wenze i-PVC isebenze, izinhlobonhlobo zezithasiselo nezigcwalisi ezifana ne-plasticizers, stabilizers, lubricants, njll. zidinga ukungezwa ngesikhathi sokucubungula.Izinsiza zokucubungula ze-ACR zingenye yezinsiza ezibalulekile zokucubungula.Ingokwesigaba sezinsiza zokucubungula i-acrylic futhi iyi-copolymer ye-methacrylate ne-acrylic ester.Izinsiza zokucubungula i-ACR zikhuthaza ukuncibilika kwezinhlelo zokucubungula ze-PVC, zithuthukise izakhiwo ze-rheological zokuncibilika, futhi izingxenye ezingahambelani ne-PVC zingathuthela ngaphandle kwesistimu ye-resin encibilikisiwe, ngaleyo ndlela ithuthukise ukusebenza kwayo kokudiliza ngaphandle kokwandisa ukusetshenziswa kwamandla kwemishini yokucubungula.Kungabonakala ukuthi izinsiza zokucubungula ze-ACR zidlala indima ebalulekile ezinhlelweni zokucubungula ze-PVC.
Izinzuzo zokusebenzisa izinsiza zokucubungula ze-ACR:
1. Inokuhambisana okuhle ne-PVC resin, kulula ukuyihlakaza ku-PVC resin, futhi kulula ukuyisebenzisa.
2. Ine-plasticity yangaphakathi futhi ingasetshenziswa ezintweni zokwenziwa kwezicathulo zodwa, izintambo kanye nezinto zekhebula, nezinto ezithambile ezibonisa obala ukuze kuncishiswe inani le-plasticizer esetshenziswayo futhi kuxazululwe inkinga yokufuduka kwendawo yama-plasticizers.
3. Ingathuthukisa kakhulu ukuguquguquka kwezinga lokushisa eliphansi namandla omthelela womkhiqizo.
4. Thuthukisa ngokuphawulekayo ukucwebezela kwendawo yomkhiqizo, ngaphezu kwe-ACR.
5. Ukuzinza okuhle kokushisa nokumelana nesimo sezulu.
6. Yehlisa i-viscosity encibilikayo, unciphise isikhathi se-plasticization, futhi ukhulise isivuno seyunithi.Thuthukisa amandla omthelela kanye nokuguquguquka kwezinga lokushisa eliphansi lomkhiqizo.
Ukushintsha i-ACR ngamanani alinganayo kunganciphisa ukusetshenziswa kwezithasiselo noma kukhuphule ukusetshenziswa kwesigcwalisi ngenkathi kugcinwa izinto ezibonakalayo, kuvula izindlela ezintsha zokuthuthukisa ikhwalithi yomkhiqizo nokunciphisa izindleko.
