zvigadzirwa

Low density polyethylene,
Yakaderera density polyethylene inoshandiswa mufirimu,

Low-density polyethylene (LDPE) iresin yekugadzira inoshandisa yakakwira kudzvanywa kuburikidza nemahara radical polymerization ye ethylene uye nekudaro inonziwo "high-pressure polyethylene".Low pressure polyethylene isinganhuhwi, isinganakidze, isina-chepfu chena zvimedu kana hupfu.Kunyungudika i131 ℃.Density 0.910-0.925 g/cm³.Kupfava poindi 120-125 ℃.Embrittlement tembiricha -70 ℃.Maximum inoshanda tembiricha 100 ℃.Nekupisa kwakanyanya kupisa, kutonhora kutonhora, kupfeka kusagadzikana uye dielectric properties, kugadzikana kwemakemikari.Inenge isinganyungudika mune chero organic solvent pakamuri tembiricha.Inogona kumira nekuora kweasidhi yakasiyana-siyana uye alkali uye zvakasiyana-siyana zvinogadzirisa munyu.Low pressure polyethylene inoshandiswa zvakanyanya mumaindasitiri emishonga uye emakemikari kugadzira zvigadzirwa zvisina maburi, senge madhiramu, mabhodhoro uye matangi ekuchengetedza.Indasitiri yechikafu inoishandisa kugadzira midziyo yekurongedza.Indasitiri yemuchina inoshandiswa kugadzira zvivharo, zvibato, mavhiri emaoko uye zvimwe zvikamu zvemuchina zvakajairika, uye indasitiri yemapepa inoshandiswa kugadzira mapepa ekugadzira.

Feature

Application

LDPE(2102TN000) yakanaka kwazvo extrusion firimu zvinhu, zvakanyanya kukodzera kugadzirwa kweinorema kurongedza firimu, yakadururwa firimu, kupisa kunopisa kurongedza firimu uye zvichingodaro.

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.

Yakaderera density polyethylene, kana LDPE, inoratidzwa nemacheni ane matavi akanyanya ane random, refu branching.LDPE ine density kubva .910 kusvika .935 magiramu pa cubic centimita (g/cc).

Kana zvasvika pakushandiswa kwayo mumafirimu epurasitiki, LDPE resin inopa kuomarara kunogamuchirika, kuchinjika, optics, uye permeability.Kunyange isina kusimba senge LLDPE resin, LDPE inopa yakanakisa shrink zvivakwa.
