Yakaderera density Polyethylene Firimu Giredhi QLT04 QLF39
Low-density polyethylene (LDPE) is a synthetic resin inoshandisa high pressure process kuburikidza nemahara radical polymerization ye ethylene uye nekudaro inonziwo "high-pressure polyethylene".Sezvo cheni yayo yemamorekuru ine matavi mazhinji marefu uye mapfupi, LDPE haina crystalline pane yakakwirira-density polyethylene (HDPE) uye density yayo yakaderera.Inoratidzira chiedza, inoshanduka, yakanaka yekudzivirira kutonhora uye kukanganisa kwekudzivirira.LDPE yakagadzikana mumakemikari.Iine kumira kwakanaka kune acids (kunze kweiyo yakasimba oxidizing acids), alkali, munyu, yakanakisa magetsi ekudzivirira zvinhu.Kupinda kwayo kwemhute kwakaderera.LDPE ine yakakwira fluidity uye yakanaka processability.Yakakodzera kushandiswa mumhando dzese dze thermoplastic processing process, senge jekiseni rekugadzira, extrusion molding, blow molding, rotomolding, coating, foaming, thermoforming, hot-jet welding uye thermal welding.
Application
LDPE giredhi remufirimu rinonyanya kushandiswa mukugadzira blowmolding kurongedza firimu, firimu rekurima uye rinogona kusanganiswa nelinear low-density polyethylene (LLDPE) kugadzira yakagadziridzwa PE.Mukuwedzera, inogona kushandiswa kupisa shrinkable kurongedza firimu, laminated firimu, firimu rinotonhora, kurongedza kwezvokurapa, multi-layer coextrusion film, heavy-duty packaging film, pipe coatings, cable sheathing, lining uye yakakwirira-kuguma kwemakemikari kupupa.
LDPE (QLT04/QLF39) yakanaka kwazvo yakajeka yakarongedza kurongedza firimu raw material.
