Tsawg ntom polyethylene
Tsawg ntom polyethylene,
Tsawg ntom polyethylene siv rau zaj duab xis,
Tsawg-density polyethylene (LDPE) yog cov khoom siv hluavtaws siv cov txheej txheem siab ntawm cov dawb radical polymerization ntawm ethylene thiab yog li hu ua "high-pressure polyethylene".Tsis tshua muaj siab polyethylene odorless, tasteless, non-toxic dawb hais los yog hmoov.Melting point yog 131 ℃.Qhov ceev 0.910-0.925 g / cm³.Softening point 120-125 ℃.Embrittlement kub -70 ℃.Ua haujlwm kub siab tshaj 100 ℃.Nrog zoo heev kub tsis kam, txias tsis kam, hnav tsis kam thiab dielectric zog, tshuaj stability.Yuav luag insoluble nyob rau hauv tej organic hnyav nyob rau hauv chav tsev kub.Muaj peev xwm tiv taus corrosion ntawm ntau yam kua qaub thiab alkali thiab ntau yam ntsev daws.Tsis tshua muaj siab polyethylene yog siv dav hauv kev lag luam tshuaj thiab tshuaj lom neeg los ua cov khoom hollow, xws li cov thoob, lub raj mis thiab cov tso tsheb hlau luam.Kev lag luam zaub mov siv nws los ua cov thawv ntim khoom.Kev lag luam tshuab yog siv los ua cov npog, tuav, tes thiab lwm yam khoom siv dav siv, thiab cov ntawv kev lag luam yog siv los ua cov ntawv hluavtaws.
Feature
Daim ntawv thov
LDPE (2102TN000) yog cov khoom siv extrusion zoo heev, feem ntau yog tsim rau kev tsim cov khoom hnyav ntim zaj duab xis, tso zaj duab xis, cua sov shrinkable ntim zaj duab xis thiab lwm yam.
Tsis muaj
Ntim, Cia thiab thauj
Cov resin yog ntim rau hauv cov hnab yas-coated polypropylene woven hnab.Qhov hnyav yog 25Kg / hnab.Cov resin yuav tsum tau muab khaws cia rau hauv ib qho chaw qhuav, qhuav warehouse thiab deb ntawm hluav taws thiab tshav ntuj ncaj qha.Nws yuav tsum tsis txhob muab tso rau hauv qhov qhib cua.Thaum lub sij hawm kev thauj mus los, cov khoom yuav tsum tsis txhob raug tshav ntuj los yog nag thiab yuav tsum tsis txhob raug thauj nrog xuab zeb, av, seem hlau, thee lossis iav.Kev thauj mus los ua ke nrog cov tshuaj lom, corrosive thiab flammable yog nruj me ntsis txwv.
Tsawg ntom ntom polyethylene, los yog LDPE, yog tus cwj pwm los ntawm cov saw hlau loj nrog random, ntev branching.LDPE muaj qhov ntom ntom ntawm .910 txog .935 grams ib cubic centimeter (g / cc).
Thaum nws los txog rau nws siv nyob rau hauv cov yeeb yaj duab yas, LDPE resins muab tau toughness, yooj, optics, thiab permeability.Thaum tsis muaj zog li LLDPE resins, LDPE muab cov khoom zoo heev.
