Izici ezithinta ukusebenza kwe-polyethylene e-chlorine (CPE):

1. Okuqukethwe kwe-chlorine
Ububanzi kanye nobudlelwano bokusebenza: Okuqukethwe kwe-chlorine kwe-CPE kuvame ukuba ngu-25% -45%. Uma okuqukethwe kwe-chlorine kungu-≥ 35%, kuba nezakhiwo zokuzicisha (LOI ≥ 28%), futhi uma kudlula u-40%, ukuvinjelwa komlilo kuthuthuka kakhulu.
Ukusebenza kwezinga lokushisa eliphansi: Uma okuqukethwe yi-chlorine kungu-30% -40%, izinto zisaqhubeka nokuguquguquka ku--30 ℃.
2. Inqubo yokufaka i-chlorine
Ukusatshalaliswa kwe-athomu ye-chlorine: I-CPE elungiselelwe ngendlela yesisombululo, indlela yokumiswa noma indlela ye-sulfurization, ukufana kokusatshalaliswa kwe-athomu ye-chlorine kuthinta ukuhambisana kwayo kanye nezakhiwo zayo zemishini.
Isakhiwo Esincane: Izinga le-chlorination lithinta izinga lokushisa lokuguqulwa kwengilazi (Tg) ye-CPE, futhi ukusebenza kwezinga lokushisa eliphansi kudinga ukuhlolwa ngokuhlaziywa kwe-thermomechanical okuguquguqukayo.
3. Ukuguqulwa kokuxuba
Ukuqinisa i-PVC: Ukuhlanganisa i-CPE ne-PVC (izingxenye ezingu-5-15 ezengeziwe) kungandisa amandla okushaqeka ngokuphindwe ka-3-5 futhi kuthuthukise ukumelana nesimo sezulu.
Ukusebenzisana okuvimbela ilangabi: Inhlanganisela ene-magnesium hydroxide (Mg (OH) ₂) inganciphisa ukuminyana kwentuthu yokushisa futhi ithuthukise ukuzinza kokushisa.
4. Uhlelo lwe-Sulfurization
Ubuningi bokuxhumanisa: Ama-peroxide (njenge-DCP) noma ama-ejenti e-thiourea vulcanizing angenza ngcono isakhiwo sokuxhumanisa se-CPE, athuthukise ukumelana nowoyela kanye namandla omshini.
5. Ukugcwalisa nokucubungula
Ama-filler angaphili: Ukwengeza i-carbon black noma i-titanium dioxide kungalungisa ukuguquguquka kombala kanye nezakhiwo zokufaka umbala, kodwa ukugcwalisa ngokweqile kunganciphisa ukuguquguquka kombala.
Izinga lokushisa lokucubungula: Izinga lokushisa lokubola kwe-CPE liphezulu kakhulu, kodwa izinga lokushisa eliphezulu kufanele ligwenywe ekubangeleni ukusabela kwe-HCl catalytic dechlorination.
6. Ukuzivumelanisa nezimo kwesicelo
Irabha ekhethekile: I-CPE enokuqukethwe kwe-chlorine okungu-25% -35% ifaneleka ezimweni ezivimbela ilangabi njengezimbobo zekhebula.
Ukuguqulwa kwe-ABS: Uhlobo lwe-C kanye ne-AZ uhlobo lwe-CPE olwakhiwe yiBontecn Group China lungathuthukisa izimfanelo ze-ABS zokuvimbela ilangabi kanye nokuwa, kunciphise inani lezinto ezivimbela ilangabi ezisetshenziswayo.
