Tsawg ceev Polyethylene cob
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 feem ntau yog siv los ua cov yeeb yaj kiab.Nws yog dav siv nyob rau hauv kev tsim cov zaj duab xis ua liaj ua teb (mulching zaj duab xis thiab shed zaj duab xis), ntim zaj duab xis (rau siv rau hauv ntim khoom qab zib, zaub thiab khoom noj khov), tshuab tshuab rau ntim kua (rau siv ntim mis, soy sauce, kua txiv, taum curds thiab soy mis nyuj), lub hnab ntim hnyav, ntim zaj duab xis, elastic zaj duab xis, zaj duab xis hauv ob sab phlu, zaj duab xis siv hauv tsev, lub hom phiaj kev lag luam ntim zaj duab xis thiab cov hnab ntim khoom noj.
LDPE kuj tau siv dav hauv kev tsim cov hlau & cable rwb thaiv tsev sheath.Hla-txuas LDPE yog cov khoom siv tseem ceeb uas siv rau hauv txheej rwb thaiv tsev ntawm cov hluav taws xob hluav taws xob.
LDPE kuj tseem siv rau hauv kev tsim cov khoom txhaj tshuaj molded (xws li paj paj, khoom siv kho mob, tshuaj thiab cov khoom ntim khoom noj) thiab extrusion-molded raj, daim hlau, hlau & cable coatings thiab cov khoom yas profiled.
LDPE kuj tseem siv los ua cov khoom siv molded hollow xws li ntim khoom noj, tshuaj, tshuaj pleev ib ce thiab tshuaj, thiab tso tsheb hlau luam.
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.
