Abubuwan da ke shafar aikin polyethylene mai sinadarin chlorine (CPE):

1. Yawan sinadarin Chlorine
Alaƙar da ke tsakanin kewayo da aiki: Yawan sinadarin chlorine na CPE yawanci kashi 25% -45% ne idan sinadarin chlorine ya kai kashi 35%, yana da kaddarorin kashe kansa (LOI ≥ 28%), kuma idan ya wuce kashi 40%, ƙarfin hana harshen wuta yana ƙaruwa sosai.
Ƙarancin zafin jiki: Lokacin da sinadarin chlorine ya kai kashi 30% -40%, kayan har yanzu suna da sassauci a -30 ℃.
2. Tsarin chlorine
Rarraba kwayar zarra ta Chlorine: CPE da aka shirya ta hanyar hanyar mafita, hanyar dakatarwa ko hanyar sulfurization, daidaiton rarraba kwayar zarra ta chlorine yana shafar daidaitonsa da halayen injiniya.
Tsarin Ƙarfi: Matsayin sinadarin chlorine yana shafar zafin canjin gilashin (Tg) na CPE, kuma ana buƙatar kimanta aikin ƙarancin zafin jiki ta hanyar nazarin thermomechanical mai ƙarfi.
3. Gyaran haɗa abubuwa
Ƙarfafa PVC: Haɗa CPE da PVC (an ƙara sassa 5-15) na iya ƙara ƙarfin tasiri sau 3-5 kuma yana ƙara juriya ga yanayi.
Haɗin kai tsakanin masu hana harshen wuta: Haɗawa da magnesium hydroxide (Mg (OH) ₂) na iya rage yawan hayakin konewa da kuma inganta kwanciyar hankali na zafi.
4. Tsarin samar da sinadarin sulfur
Yawan haɗuwa: Peroxides (kamar DCP) ko thiourea vulcanizing agents na iya inganta tsarin haɗin gwiwa na CPE, inganta juriya ga mai da ƙarfin injina.
5. Cikowa da sarrafawa
Cikakkun abubuwan da ba su da sinadarai: Ƙara carbon black ko titanium dioxide na iya daidaita yanayin watsawa da launi, amma cikawa da yawa na iya rage iskar shaka.
Zafin sarrafawa: Zafin ruɓewar CPE yana da girma sosai, amma ya kamata a guji yawan zafin jiki daga haifar da amsawar dechlorination na HCl.
6. Daidaita amfani
Roba ta musamman: CPE mai sinadarin chlorine na 25% -35% ya dace da yanayi masu hana harshen wuta kamar murfin kebul.
Gyaran ABS: CPE na nau'in C da AZ wanda Bontecn Group China ta ƙirƙira zai iya haɓaka juriyar harshen wuta da kuma hana digawa na ABS, yana rage yawan masu hana harshen wuta da ake amfani da su.
