Kodi Mitundu Yosiyanasiyana ya Polyethylene Ndi Chiyani?

Polyethylene nthawi zambiri imagawika m'gulu limodzi mwazinthu zazikulu zingapo, zomwe zimaphatikiza LDPE, LLDPE, HDPE, ndi Ultrahigh Molecular Weight Polypropylene. Mitundu ina ndi monga Medium Density Polyethylene (MDPE), Ultra-low-molecular-weight polyethylene (ULMWPE kapena PE-WAX), High-molecular-weight polyethylene (HMWPE), High-density cross-linked polyethylene (HDXLPE), Cross-linked polyethylene (PEX kapena XLPE), Polyethylene yotsika kwambiri (VLDPE), ndi chlorinated polyethylene (CPE).

Low-Density Polyethylene (LDPE) ndi chinthu chosinthika kwambiri chokhala ndi mawonekedwe apadera otaya omwe amachititsa kuti ikhale yoyenera kwambiri pamatumba ogula ndi mapulogalamu ena apulasitiki apulasitiki. LDPE ili ndi ductility kwambiri koma mphamvu yotsika kwambiri, yomwe imawonekera m'dziko lenileni ndi chizolowezi chake chotambasula chikavuta.
Linear Low Density Polyethylene (LLDPE) ndiyofanana kwambiri ndi LDPE, koma imapereka maubwino owonjezera. Makamaka, mawonekedwe a LLDPE amatha kusinthidwa posintha ma formula, ndipo njira yonse yopangira LLDPE nthawi zambiri imakhala yochepa mphamvu kuposa LDPE.
High-Density Polyethylene (HDPE) ndi pulasitiki yolimba, yolimba pang'ono yokhala ndi crystalline kwambiri polyethylene-hdpe-trashcan-1. Amagwiritsidwa ntchito kaŵirikaŵiri m’mapulasitiki popanga makatoni a mkaka, zotsukira zovala, zotayiramo zinyalala, ndi matabwa oduliramo.

Ultrahigh Molecular Weight Polyethylene (UHMW) ndi polyethylene wandiweyani kwambiri, wokhala ndi zolemera zamamolekyulu zomwe zimakhala zazikulu kuposa HDPE. Itha kulumphidwa kukhala ulusi wokhala ndi mphamvu zolimba kwambiri kuposa zitsulo ndipo nthawi zambiri imaphatikizidwa muzovala zoteteza zipolopolo ndi zida zina zogwira ntchito kwambiri.
