Polyethylene CAS 9002-88-4
Polyethylene ndi saturated hydrocarbon ndi kapangidwe ofanana paraffin, amene ndi mkulu maselo kulemera kupanga zinthu zopangidwa ndi polymerizing ethylene. Mamolekyu a polyethylene alibe majini a polarity, kuyamwa kwamadzi otsika, komanso kukhazikika bwino. Sasungunuke mu zosungunulira wamba pa kutentha kwa chipinda, kukhazikika ku mowa, ethers, ketoni, esters, ofooka zidulo, ndi zofooka zapansi. Koma imatha kukwiririka m’ma hydrocarbon amafuta, ma hydrocarbon onunkhira, ndi ma halogenated hydrocarbons, kuipitsidwa ndi ma asidi amphamvu okhala ndi okosijeni, ndi kulowetsedwa ndi okosijeni ikatenthedwa kapena kuunikiridwa mumpweya.

1. Polyethylene akhoza kukonzedwa mu mafilimu, waya ndi chingwe sheaths, mapaipi, zosiyanasiyana dzenje zinthu, jekeseni kuumbidwa mankhwala, ulusi, etc. Amagwiritsidwa ntchito m'mafakitale monga ulimi, ma CD, ndi magalimoto.
2. Pe angagwiritsidwe ntchito kupanga mbiri kwambiri pulasitiki mbiri ndi mphira zina,
3. Itha kugwiritsidwa ntchito ngati zopangira zinthu zamafakitale ndi zaulimi, chakudya, filimu yovundikira mmera, njira ndi filimu yotsutsa-seepage, etc.
4. Amagwiritsidwa ntchito m'makampani azakudya monga chothandizira kutafuna maswiti a gummy.
5. Amagwiritsidwa ntchito m'malo mwa zitsulo, amathanso kugwiritsidwa ntchito ngati mafilimu apadera, zotengera zazikulu, ma conduits akuluakulu, mbale, ndi zipangizo zopangira sintered.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
