Menene polyethylene mai chlorine da halaye:

1. Polyethylene mai sinadarin chlorine, wanda aka fi sani da CPE a Turanci, wani nau'in polyethylene ne. Polyethylene mai sinadarin chlorine (CPE) wani abu ne da ake samu ta hanyar maye gurbin sinadarin hydrogen a jikin polyethylene mai yawan yawa (HDPE) da sinadarin chlorine. CPE yana bayyana a matsayin farin foda, ba shi da guba kuma ba shi da wari.
2. Polyethylene mai sinadarin chlorine da aka yi da polyethylene mai ƙarancin matsin lamba HDPE yana da juriya ga yawan zafin jiki da tsufa na zafi fiye da polyethylene mai sinadarin chlorine da aka yi da polyethylene mai yawan matsin lamba. Gabaɗaya, polyethylene mai yawan 0.93-0.96g/cm3, matsakaicin nauyin kwayoyin halitta na 50000 zuwa 250000, da kuma ma'aunin narkewa tsakanin 0.01 da 2.0g/10min ana amfani da shi sosai don samar da polyethylene mai sinadarin chlorine. Matsayin chlorine na polyethylene mai sinadarin chlorine yana da tasiri mai mahimmanci akan kaddarorinsa. Lokacin da sinadarin chlorine ya ƙasa da 15%, filastik ne; Lokacin da sinadarin chlorine ya kai 16-24%, elastomer ne mai thermoplastic; Elastomers kamar roba tare da sinadarin chlorine tsakanin 25-48%; Lokacin da sinadarin chlorine ya kai 49-58%, polymer ne mai tauri mai kama da fata; Lokacin da sinadarin chlorine ya kai 73%, ya zama resin mai rauni. Shigar da kusan kashi 27% na chlorine a cikin polyethylene mai matsin lamba yana kawar da crystallization gaba ɗaya, yayin da shigar da kusan kashi 30% na chlorine a cikin polyethylene mai ƙarancin matsin lamba tare da babban crystallinity shima yana kawar da crystallization gaba ɗaya. A matsayin roba mai elastomer, yawan chlorine ya fi kyau a cikin kewayon 30-40%. A halin yanzu, yawan chlorine na robar polyethylene mai chlorine a cikin kasuwanci galibi yana cikin kewayon 25-45%. Lokacin da yawan chlorine ya ƙaru, juriyar mai, iska, da juriyar harshen wuta suna inganta; Lokacin da yawan chlorine ya ragu, juriyar sanyi, juriya, da aikin lanƙwasawa sun fi kyau.
2. Halayen CPE na Chlorinated Polyethylene
1) CPE roba ce mai cike da sinadarai masu juriya ga zafi da iskar oxygen, juriya ga tsufa ta ozone, juriya ga acid da alkali, da kuma halayen sinadarai.
2) CPE yana da kyakkyawan juriya ga mai, tare da kyakkyawan juriya ga man ASTM 1 da man ASTM 2, wanda yayi daidai da NBR; Kyakkyawan juriya ga man ASTM No. 3, ya fi CR kuma yayi daidai da CSM.
3) CPE ya ƙunshi sinadarin chlorine, wanda ke da kyawawan kaddarorin hana harshen wuta kuma yana da halayen ƙonewa da hana ɗigon ruwa. Ana iya haɗa shi da masu hana harshen wuta bisa antimony, paraffin mai chlorine, da Al (OH) 3 a cikin gwargwado mai dacewa don samun kayan hana harshen wuta masu kyau da ƙarancin farashi.
4) CPE ba shi da guba, ba shi da ƙarfe mai nauyi da PAHs, kuma ya cika dukkan buƙatun muhalli.
5) CPE yana da babban aikin cikawa kuma yana iya samar da samfuran da suka cika buƙatun aiki daban-daban. CPE yana da kyakkyawan aikin sarrafawa, kuma akwai matakai da yawa da za a zaɓa daga ciki tare da ɗanko tsakanin 50-100 na Mooney.
