HDPE ndi chiyani?

HDPE imatanthauzidwa ndi kachulukidwe kokulirapo kapena kofanana ndi 0.941 g/cm3.HDPE ili ndi gawo lotsika la nthambi ndipo motero mphamvu za intermolecular ndi mphamvu zamanjenje.HDPE imatha kupangidwa ndi chromium/silica catalysts, Ziegler-Natta catalysts kapena metallocene catalysts.Kuperewera kwa nthambi kumatsimikiziridwa ndi kusankha koyenera kwa chothandizira (monga chromium catalysts kapena Ziegler-Natta catalysts) ndi momwe zimachitikira.

HDPE imagwiritsidwa ntchito popanga zinthu ndi kulongedza zinthu monga mitsuko yamkaka, mabotolo otsukira, machubu a margarine, zotengera zinyalala ndi mapaipi amadzi.HDPE imagwiritsidwanso ntchito kwambiri popanga zozimitsa moto.M'machubu aatali mosiyanasiyana (kutengera kukula kwake), HDPE imagwiritsidwa ntchito m'malo mwa machubu amatope omwe amaperekedwa pazifukwa ziwiri zazikulu.Choyamba, ndi otetezeka kwambiri kuposa machubu a makatoni omwe amaperekedwa chifukwa chipolopolo chikapanda kugwira ntchito ndikuphulika mkati ("mphika wamaluwa") chubu la HDPE, chubucho sichidzasweka.Chifukwa chachiwiri ndi chakuti amatha kugwiritsidwanso ntchito kulola opanga kupanga ma racks angapo amatope.Akatswiri a Pyrotechnicians amaletsa kugwiritsa ntchito machubu a PVC m'machubu amatope chifukwa amatha kusweka, kutumiza zidutswa za pulasitiki kwa owonerera omwe angathe, ndipo sizidzawonekera pa X-ray.
