Kodi pali kusiyana kotani pakati pa LDPE ndi PE?
LDPE vs. PE: Kumvetsetsa Kusiyana Kwakukulu kwa Katundu ndi Ntchito Polyethylene (PE) ndi zosunthika pulasitiki chuma ndi osiyanasiyana ntchito. Komabe, pali mitundu yosiyanasiyana ya PE, iliyonse ili ndi mawonekedwe akeake komanso ntchito zake. Mitundu iwiri yodziwika bwino ndi polyethylene yotsika kwambiri (LDPE) ndi polyethylene (PE). 1.Properties LDPE imadziwika ndi kuchepa kwake, kusinthasintha, ndi kulimba. Ili ndi digiri yapamwamba ya crystallinity, yomwe imapangitsa kuti ikhale yowoneka bwino komanso imapangitsa kuti ikhale yosagwirizana ndi mankhwala komansoWerengani zambiri …
Kusiyana kwa LDPE, HDPE, ndi LLDPE
Polyethylene ndi imodzi mwa ma resin asanu akuluakulu opangira, ndipo China pakadali pano ndiye kampani yotumiza kunja komanso yachiwiri pakugwiritsa ntchito polyethylene. Polyethylene imagawidwa makamaka m'magulu atatu: polyethylene yochuluka kwambiri (HDPE), polyethylene yotsika kwambiri (LDPE), polyethylene yotsika kwambiri (LLDPE). Kuyerekeza kwa makhalidwe a zinthu za HDPE, LDPE ndi LLDPE Polyethylene yochuluka kwambiri siili ndi poizoni, yopanda kukoma, yopanda fungo, ndipo ili ndi kuchuluka kwa 0.940 ~ 0.976g/cm3, komwe ndi chinthu chopangidwa ndi polymerization pansi pa mikhalidwe yotsika kwambiri pansi pa catalysis ya Werengani Zambiri …
Kodi PE Powder Coating ndi nthawi yake ya moyo?
Kodi chophimba cha ufa cha PE n'chiyani? Chophimba cha ufa cha PE chimatanthauza mtundu wa chophimba cha ufa chopangidwa ndi polyethylene resin. Chili ndi makhalidwe awa: Kukana dzimbiri bwino: Kungapereke chitetezo chabwino pa chinthu chophimbidwa. Kukana kwabwino kwa kukhudza: Kuli ndi kulimba komanso kulimba.

Kusiyana Pakati pa LLDPE ndi LDPE
Kusiyana pakati pa polyethylene yotsika kwambiri (LLDPE) ndi polyethylene yotsika kwambiri (LDPE) 1. Tanthauzo: Polyethylene yotsika kwambiri (LLDPE) ndi polyethylene yotsika kwambiri (LDPE) zonse ndi zinthu zapulasitiki zochokera ku ethylene ngati zinthu zazikulu zopangira.

Kapangidwe ka thupi: LLDPE imawonetsa kusiyana kwakukulu pankhani ya kachulukidwe. Werengani Zambiri …
Kusiyanitsa High density polyethylene (HDPE) kuchokera ku LDPE
Polyethylene yochuluka kwambiri (HDPE) ndi polyethylene yotsika kwambiri (LDPE) ndi mitundu iwiri ya ma polima a polyethylene omwe ali ndi makhalidwe osiyana. Nazi kusiyana kwakukulu pakati pawo: 1. Kapangidwe ka Molecular: HDPE ili ndi kapangidwe kolunjika kokhala ndi nthambi zochepa, zomwe zimapangitsa kuti pakhale kuchuluka kwakukulu ndi crystallinity. Koma LDPE ili ndi kapangidwe kokhala ndi nthambi zambiri komanso kosasinthasintha, zomwe zimapangitsa kuti pakhale kuchuluka kochepa komanso crystallinity yochepa. 2. Kuchuluka: Monga momwe dzinalo likusonyezera, polyethylene yochuluka kwambiri (HDPE) ili ndi kuchuluka kwakukulu poyerekeza ndi kochepa Werengani Zambiri …
Kodi pulasitiki ya polyethylene yapamwamba kwambiri ndi chiyani?
Polyethylene yochuluka kwambiri (HDPE) ndi mtundu wa pulasitiki wodziwika ndi chiŵerengero chake champhamvu kwambiri. Imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana chifukwa cha kukana kwake mankhwala, kulimba, komanso kusinthasintha. HDPE imapangidwa kudzera mu polymerization ya ethylene monomers, zomwe zimapangitsa kuti pakhale unyolo wa polima wolunjika wokhala ndi kristalo wambiri. HDPE imadziwika ndi kuchuluka kwake kwakukulu, komwe kumaipatsa mphamvu komanso kulimba kwambiri poyerekeza ndi mitundu ina ya polyethylene.

Kodi polyethylene pulasitiki?
Inde, polyethylene ndi mtundu wa pulasitiki. Ndi polima yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera komanso kusinthasintha kwake. Polyethylene ndi chinthu chopepuka, cholimba, komanso chosinthasintha chomwe chingapangidwe mosavuta kukhala mawonekedwe ndi mawonekedwe osiyanasiyana. Polyethylene imapangidwa kuchokera ku polymerization ya ethylene monomers. Ethylene ndi mpweya wa hydrocarbon womwe umachokera ku gasi wachilengedwe kapena mafuta. Kudzera mu njira yotchedwa polymerization, mamolekyu a ethylene amalumikizidwa pamodzi ndi mankhwala kuti apange maunyolo ataliatali Werengani Zambiri …
