Ukwenziwa kwepulasitiki kubhekisela enqubweni yokugoqa noma yokukhipha irabha eluhlaza ukuze kuthuthukiswe ukuguquguquka kwayo, ukugeleza kwayo, kanye nezinye izakhiwo, ukuze kube lula ukucubungula okulandelayo njengokubumba.
1. Izimo zokucubungula:
Ngaphansi kwezimo ezijwayelekile zokucubungula, izinga lokufakelwa kwepulasitiki kwe-resin ye-PVC liyanda ngokwanda kwezinga lokushisa lokucubungula kanye nezinga lokugunda. Lapho izinga lokushisa lokucubungula liphezulu, umehluko wokushisa uba mkhulu, futhi izinga lokudlulisa ukushisa lishesha kakhulu. Ngenxa yokuthi i-PVC ingumqhubi wokushisa ompofu, ukwanda kwesivinini sokugunda kuzosheshisa ukukhiqizwa kokushisa okungqubuzanayo phakathi kwezinto, kanye nokuvama kokuxhumana phakathi kwezinto nezinto, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokushintshana kokushisa.
2. Isakhiwo se-resin:
Izinga lokushisa lokushintsha kwengilazi kanye nephuzu lokuncibilika kwe-PVC kuyanda ngokwanda kwesisindo sama-molecule kanye nokukristala, kanti nezinga lokwenziwa kwe-PVC libe yipulasitiki nalo liba nzima.
3: Izici zefomula
Ukusetshenziswa kwezinto zokugcoba, izinto zokugcoba ngepulasitiki, izinsiza zokucubungula, izinto zokuguqula impact, izinto zokugcwalisa, izinto zokuqinisa, njll. enkambisweni yokucubungula i-PVC kunomthelela omkhulu ezimpahleni zokwenziwa kwepulasitiki nge-PVC. Yiqiniso, izingxenye ezahlukene zinezindlela ezahlukene kanye namazinga omthelela ezimpahleni zokwenziwa kwepulasitiki nge-PVC ngenxa yezinjongo zazo ezahlukene zokusetshenziswa.
4. Inqubo yokuxuba nokucubungula
Ukuxuba kuyinqubo yokuhlanganisa i-resin ye-PVC ngezithasiselo ezifana neziqinisi zokushisa, izilungisi, izinto zokugcoba, izigcwalisi, kanye nemibala. Imishini eyinhloko esetshenziswayo umshini wokuxova ngesivinini esikhulu kanye nomshini wokupholisa. Inqubo yokuxuba incike emandleni okungqubuzana kanye nokusika okuhlangene okukhiqizwa amandla omshini ezintweni ukuze kuhlungwe futhi kushiswe izinto, kuncibilikiswe ezinye izithasiselo bese zimbozwa ebusweni be-resin ye-PVC. I-resin ye-PVC icwengisiswa ngaphansi kokunqunywa kanye nokungqubuzana, futhi ubuso bayo bubonakala buthambile futhi bunezimbobo ngaphansi kokushisa. I-ejenti eyisizayo inamathela ebusweni futhi ifinyelele ekuhlanganisweni. Izinga lokushisa liyakhula, futhi ubuso bezinhlayiya buyancibilika, okuholela ekwandeni kobuningi bezinhlayiya.
