Tsawg ceev Polyethylene Zaj duab xis Qib QLT04 QLF39
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".Txij li nws cov saw hlau molecular muaj ntau ceg ntev thiab luv, LDPE tsis tshua muaj crystalline dua li high-density polyethylene (HDPE) thiab nws qhov ntom yog qis dua.Nws nta lub teeb, hloov tau, zoo khov tsis kam thiab cuam tshuam tsis kam.LDPE yog tshuaj ruaj khov.Nws muaj kev tiv thaiv zoo rau cov kua qaub (tshwj tsis yog muaj zog oxidizing acids), alkali, ntsev, hluav taws xob rwb thaiv tsev zoo heev.Nws vapor nkag tus nqi yog tsawg.LDPE muaj fluidity siab thiab ua tau zoo.Nws yog tsim rau siv nyob rau hauv txhua yam ntawm cov txheej txheem thermoplastic, xws li txhaj tshuaj molding, extrusion molding, tshuab moulding, rotomolding, txheej, foaming, thermoforming, kub-dav hlau vuam thiab thermal vuam.
Daim ntawv thov
LDPE zaj duab xis qib feem ntau yog siv rau hauv kev tsim cov tshuab ntim tshuab, cov yeeb yaj kiab ua liaj ua teb thiab tuaj yeem sib xyaw nrog cov kab uas tsis tshua muaj siab polyethylene (LLDPE) los tsim cov PE hloov.Tsis tas li ntawd, nws tuaj yeem siv rau cov khoom siv hluav taws xob ua kom sov shrinkable ntim zaj duab xis, laminated zaj duab xis, khov zaj duab xis, ntim kho mob, ntau txheej coextrusion zaj duab xis, hnyav ntim zaj duab xis, yeeb nkab txheej, cable sheathing, hauv ob sab phlu thiab high-end tshuaj foaming.
LDPE (QLT04/QLF39) yog ib qho zoo heev pob tshab ntim zaj duab xis raw khoom.

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.
