Umphumela Wokwengezwa kwe-CPE ku-PVC

1. Izici ezintathu ezinkulu ezithinta ukusebenza kwe-CPE
Okokuqala, uhlobo lwe-CPE olusetshenziswayo. I-CPE etholakala ku-polyethylene enesisindo sama-molecule aphezulu inamandla amakhulu okubamba, kodwa ukunamathelana phakathi kwale CPE ne-resin ye-PVC kuphansi. I-CPE etholakala ku-polyethylene enesisindo sama-molecule ephansi inamandla amancane okubamba, kanti i-CPE etholakala ku-polyethylene enesisindo sama-high density inokumelana okuhle nokushisa.
Okwesibili, ubukhulu bezinhlayiya zezinto zokusetshenziswa. Uma ubukhulu bezinhlayiya buncane kakhulu, kulula ukwakha ijeli noma i-CPE ehlanganisiwe, futhi uma ubukhulu bezinhlayiya bukhulu kakhulu, ukusatshalaliswa kwe-chlorine akulingana.
Futhi, yizinga le-chlorination ye-CPE. Uma okuqukethwe kwe-chlorine kungaphansi kwama-25%, akuhambelani kahle ne-PVC futhi akukwazi ukusetshenziswa njengesiguquli; Uma okuqukethwe kwe-chlorine kungaphezu kwama-40%, kuhambelana kahle ne-PVC futhi kungasetshenziswa njenge-plasticizer eqinile, akufanelekile njengesiguquli somthelela; i-CPE enokuqukethwe kwe-chlorine okungu-36-38% inokuguquguquka okuhle nokuhambisana okuhle ne-PVC, okwenza isetshenziswe kabanzi njengesiguquli somthelela we-PVC. Njengamanje, i-CPE enokuqukethwe kwe-chlorine okungu-35% ivame ukusetshenziswa. I-CPE enokuqukethwe kwe-chlorine okungu-35% inokukhanya okuphansi kanye nokushisa kokushintsha kwengilazi, ukuqina okuhle kwerabha, kanye nokuhambisana okufanele ne-PVC. Isetshenziswa kabanzi njengesiguquli somthelela wemikhiqizo eqinile ye-PVC.
2, Umphumela Wokwengezwa kwe-CPE ku-PVC
Uma inani lokwengeza lingaphansi kwemizuzu eyi-10, amandla omthelela we-PVC anda ngokushesha ngokungezwa kwe-CPE, kodwa ukwandisa inani lokwengeza le-CPE kuphumela ekuthuthukisweni okuncane kwamandla omthelela we-PVC. Ngakho-ke, njenge-ejenti emelana nomthelela, inani elifanele le-CPE okufanele lingezwe yizingxenye eziyi-8-10. Njengoba i-CPE ikhula, amandla okudonsa engxube ye-PVC ayaqhubeka nokwehla, kuyilapho ukunwebeka lapho kuphuka kukhuphuka. Uma ukuqina kuvezwa njengomkhiqizo wamandla okudonsa kanye nokwelulwa lapho kuphuka, kusobala ukuthi ukuqina kwe-PVC kuzokhula kakhulu ngokunyuka kokungezwa kwe-CPE.
