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, lubricant, njll. zidinga ukungezwa ngesikhathi sokucubungula kwayo. 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, kanye nezinto ezibonakalayo ezithambile ukuze kuncishiswe inani le-plasticizer elisetshenziswa 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 ngenani elilinganayo kunganciphisa ukusetshenziswa kwezithasiselo noma kukhuphule ukusetshenziswa kwesigcwalisi ngenkathi kugcinwa izinto ezibonakalayo, kuvula izindlela ezintsha zokuthuthukisa ikhwalithi yomkhiqizo nokunciphisa izindleko.
