Izinyathelo zokuphepha lapho ukhetha i-polyethylene ene-chlorine

Izinyathelo zokuphepha lapho ukhetha i-polyethylene ene-chlorine:
I-CPE chlorine polyethylene isetshenziswa kabanzi emigqeni kamazibuthe yesiqandisi, kumaphrofayili eminyango namafasitela e-PVC, amashidi amapayipi, izinto zokufaka, ama-blind, ama-wire kanye nama-cable sheaths, ama-roll angangeni manzi, ama-conveyor joints avimbela ilangabi, kanye namapayipi erabha. Amathayi, ifilimu, njll.
I-polyethylene ene-chlorine (CPE) iyinto ecwebezelayo emhlophe ecwebezelayo noma encane eyenziwe ngokushintsha ama-athomu e-hydrogen ku-polyethylene ekhethekile enesisindo esikhulu ngama-athomu e-chlorine. Inokuguquguquka okuhle, izinga lokushisa eliphansi lokuphuka, ukumelana nesimo sezulu esihle, ukumelana nokuguga, ukumelana namakhemikhali, ukumelana ne-ozone, ukulinda ilangabi nezinye izici. Iyahambisana namapulasitiki ahlukahlukene kanye nerabha futhi inokusebenza okuhle kokugcwalisa. Ngokusho kokusebenza komkhiqizo okuhlukile, i-polyethylene ene-chlorine ye-CPE ingasetshenziswa njenge-impact modifier, i-plastic modifier compatibilizer, kanye nerabha ekhethekile yokwenziwa.
I-CPE chlorine polyethylene isetshenziswa kabanzi emigqeni kamazibuthe yesiqandisi, kumaphrofayili eminyango namafasitela e-PVC, amashidi amapayipi, izinto zokufaka, ama-blinds, ama-wire kanye nama-cable sheaths, ama-roll angangeni manzi, ama-conveyor joints avimbela ilangabi, amapayipi erabha, amathayi emoto, amafilimu, njll.
Izinyathelo zokuqapha zokuthenga zifaka:
1. Uma ukhetha i-polyethylene ene-chlorine (CPE), kufanele kuqashelwe izinga elifanele. Amabanga ahlukene anokuqukethwe kwe-chlorine okuhlukile kanye nokusebenza okuhlukile. Isibonelo, i-CPE135A enokuqukethwe kwe-chlorine okungu-35% kufanele ikhethwe njenge-PVC impact modifier.
2. Ukuqinisekisa ikhwalithi yomkhiqizo, kubalulekile ukukhetha imikhiqizo evela kubakhiqizi abadumile.
3. Ukuqinisekisa ukuthi umkhiqizo uyi-CPE emsulwa yini, ngoba i-CPE eningi eshibhile ethengiswa ngabathengisi ayihlanzekile futhi izofaka impuphu ye-calcium ukuze kuncishiswe izindleko. Uma nje ishiswa ku-150 ℃ kuhhavini, uma iphenduka kancane kancane ibe phuzi, kumele kube ngenxa yokwengezwa kwempuphu ye-calcium.
