1, Izinto ezintathu ezinkulu ezithinta ukusebenza kwe-CPE
Okokuqala, wuhlobo lwe-CPE olusetshenziswayo. I-CPE etholwe ku-polyethylene enesisindo samangqamuzana aphezulu ine-viscosity ephezulu namandla aqinile, kodwa ukunamathela phakathi kwale CPE ne-PVC resin kuphansi. I-CPE etholwe ku-polyethylene enesisindo esiphansi se-molecular ine-viscosity ephansi namandla aqinile, futhi i-CPE etholakala ku-polyethylene ephezulu kakhulu inokumelana nokushisa okuhle.
Okwesibili, ubukhulu bezinhlayiya zempahla eluhlaza. Uma usayizi wezinhlayiyana mncane kakhulu, kulula ukwenza i-jelly noma i-CPE eyi-clumpy, futhi uma usayizi wezinhlayiyana mkhulu kakhulu, ukusatshalaliswa kwe-chlorine akulingani.
Nakulokhu futhi, izinga le-CPE chlorination. Uma okuqukethwe kwe-chlorine kungaphansi kwama-25%, kunokungahambisani kahle ne-PVC futhi ayikwazi ukusetshenziswa njengesilungisi; Uma okuqukethwe kwe-chlorine kungaphezu kuka-40%, kunokuhambisana okuhle ne-PVC futhi ingasetshenziswa njengepulasitiki eqinile, engafaneleki njengesishintshi somthelela; I-CPE enokuqukethwe kwe-chlorine engu-36-38% inokunwebeka okuhle nokuhambisana ne-PVC, okuyenza isetshenziswe kabanzi njengesishintshi somthelela se-PVC. Njengamanje, i-CPE ene-chlorine engu-35% isetshenziswa kakhulu. I-CPE ene-chlorine ecishe ibe ngu-35% inobucwebe obuphansi kanye nezinga lokushisa lokushintsha kwengilazi, ukunwebeka okuhle kwenjoloba, nokuhambisana okufanele ne-PVC. Isetshenziswa kabanzi njengesiguquli sethonya semikhiqizo eqinile ye-PVC.
2, Umphumela we-CPE Addition ku-PVC
Uma inani elingeziwe lingaphansi kwamaminithi angu-10, amandla omthelela we-PVC akhula ngokushesha ngokungezwa kwe-CPE, kodwa ngokuqhubekayo ukwandisa inani elingeziwe le-CPE kuholela ekuthuthukisweni okuncane kumandla womthelela we-PVC. Ngakho-ke, njenge-ejenti emelana nomthelela, inani elifanele le-CPE elizongezwa izingxenye eziyi-8-10. Njengoba i-CPE ikhula, amandla aqinile enhlanganisela ye-PVC ayaqhubeka nokuncipha, kuyilapho ubude ngesikhathi sekhefu buyakhula. Uma ukuqina kubonakaliswa njengomkhiqizo wamandla aqinile kanye nobude ngesikhathi sekhefu, kusobala ukuthi ukuqina kwe-PVC kuzokwanda kakhulu ngokwanda kokwengezwa kwe-CPE.
