zvigadzirwa

LDPE resin QLT04 yemhando yepamusoro firimu,
LDPE firimu giredhi QLT04, LDPE resin kugadzira yakakwira pachena firimu,

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.

Parameters

Package, Kuchengeta uye Kutakura

Iyo resin inoputirwa mukati memukati firimu-yakavharwa polypropylene yakarukwa masaga.Huremu hwemambure i25Kg / bhegi.Iyo resin inofanira kuchengetwa munzvimbo yakaoma, yakaoma uye kure nemoto uye zuva rakananga.Hazvifanirwe kuunganidzwa pamhepo.Panguva yekufambisa, chigadzirwa hachifanirwe kuratidzwa kune chiedza chezuva chakasimba kana mvura uye hachifanirwe kutakurwa pamwe chete nejecha, ivhu, zvimedu zvesimbi, marasha kana girazi.Kufambisa pamwe chete nezvinhu zvine chepfu, zvinopisa uye zvinopisa zvinorambidzwa zvachose.

Zibo Junhai Chemical yakapa LDPE resin yekugadzirwa kwefirimu pachena.
