I-PVC ibucayi kakhulu ekushiseni. Lapho izinga lokushisa lifinyelela ku-90 ℃, kuqala ukusabela okuncane kokubola kokushisa. Lapho izinga lokushisa lenyuka laya ku-120 ℃, ukusabela kokubola kuyaqina. Ngemva kokushisa ku-150 ℃ imizuzu eyi-10, i-resin ye-PVC ishintsha kancane kancane kusuka kumbala wayo omhlophe wokuqala iye kophuzi, obomvu, onsundu, nomnyama. Izinga lokushisa lokucubungula i-PVC ukuze ifinyelele isimo sokugeleza okunamandla kudingeka libe phezulu kunaleli zinga lokushisa. Ngakho-ke, ukuze i-PVC ibe wusizo, izithasiselo ezahlukahlukene kanye nezigcwalisi ezifana nama-plasticizer, ama-stabilizer, ama-lubricant, njll. kudingeka zengezwe ngesikhathi sokucubungula kwayo. Izinsiza zokucubungula i-ACR zingenye yezinsiza ezibalulekile zokucubungula. Ingeyesigaba sezinsiza zokucubungula i-acrylic futhi iyi-copolymer ye-methacrylate kanye ne-acrylic ester. Izinsiza zokucubungula i-ACR zikhuthaza ukuncibilika kwezinhlelo zokucubungula i-PVC, zithuthukise izakhiwo ze-rheological zokuncibilika, futhi izingxenye ezingahambisani ne-PVC zingathutha ngaphandle kohlelo lwe-resin oluncibilikisiwe, ngaleyo ndlela zithuthukise ukusebenza kwayo kokuncibilika ngaphandle kokwandisa ukusetshenziswa kwamandla kwemishini yokucubungula. Kungabonakala ukuthi izinsiza zokucubungula i-ACR zidlala indima ebalulekile ezinhlelweni zokucubungula i-PVC.
Izinzuzo zokusebenzisa izinsiza zokucubungula i-ACR:
1. Ihambisana kahle ne-resin ye-PVC, kulula ukuyihlakaza ku-resin ye-PVC, futhi kulula ukuyisebenzisa.
2. Ine-plasticity yangaphakathi futhi ingasetshenziswa ezintweni zezicathulo, izinto zentambo nezekhebula, kanye nezinto ezithambile ezisobala ukuze kuncishiswe inani le-plasticizer esetshenziswayo futhi kuxazululwe inkinga yokufuduka kobuso be-plasticizer.
3. Kungathuthukisa kakhulu ukuguquguquka kwezinga lokushisa eliphansi kanye namandla omthelela womkhiqizo.
4. Kuthuthukisa kakhulu ukukhazimula komkhiqizo, okungaphezu kwe-ACR.
5. Ukuqina okuhle kokushisa kanye nokumelana nesimo sezulu.
6. Nciphisa ukuncibilika kokuncibilika, nciphisa isikhathi sokwenziwa kwepulasitiki, futhi wandise isivuno seyunithi. Thuthukisa amandla omthelela kanye nokuguquguquka okuphansi komkhiqizo ekushiseni.
Ukushintsha i-ACR ngobuningi obulinganayo kunganciphisa ukusetshenziswa kokugcoba noma kwandise ukusetshenziswa kokugcwalisa ngenkathi kugcinwa izakhiwo zezinto ezibonakalayo, kuvulwe izindlela ezintsha zokuthuthukisa ikhwalithi yomkhiqizo nokunciphisa izindleko.
