Kodi HDPE ndi chiyani?

HDPE imatanthauzidwa ndi kuchuluka kwa 0.941 g/cm3. HDPE ili ndi nthambi zochepa ndipo motero imakhala ndi mphamvu zamphamvu pakati pa mamolekyulu komanso mphamvu yokoka. HDPE imatha kupangidwa ndi ma catalyst a chromium/silica, ma catalyst a Ziegler-Natta kapena ma metallocene catalyst. Kusowa kwa nthambi kumatsimikiziridwa ndi kusankha koyenera kwa catalyst (monga ma catalyst a chromium kapena ma catalyst a Ziegler-Natta) ndi momwe zimachitikira.

HDPE imagwiritsidwa ntchito pazinthu ndi ma phukusi monga mitsuko ya mkaka, mabotolo otsukira, mabafa a margarine, ziwiya za zinyalala ndi mapaipi amadzi. HDPE imagwiritsidwanso ntchito kwambiri popanga zozimitsira moto. M'machubu a kutalika kosiyanasiyana (kutengera kukula kwa zida), HDPE imagwiritsidwa ntchito m'malo mwa machubu a makatoni operekedwa pazifukwa ziwiri zazikulu. Choyamba, ndi yotetezeka kwambiri kuposa machubu a makatoni operekedwa chifukwa ngati chipolopolo chingawonongeke ndikuphulika mkati ("mphika wa maluwa") chubu cha HDPE, chubu sichidzasweka. Chifukwa chachiwiri ndikuti amatha kugwiritsidwanso ntchito kulola opanga kupanga zida zambiri zodulira. Akatswiri a pyrotechnical amaletsa kugwiritsa ntchito mapaipi a PVC m'machubu a makatoni chifukwa nthawi zambiri amasweka, kutumiza zidutswa za pulasitiki kwa owonera, ndipo sizidzawonekera mu X-ray.
