Tsawg ntom polyethylene rau tshuab molded zaj duab xis,
LDPE zaj duab xis qib, ldpe rau zaj duab xis ntau lawm,

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.

Kev xaiv ntawm polyethylene tshuab-molded zaj duab xis khoom

1. Cov khoom siv raw uas tau xaiv yuav tsum yog cov tshuab ua cov yeeb yaj kiab qib polyethylene resin hais, uas muaj qhov tsim nyog tus neeg sawv cev smoothing,

Xyuas kom qhib zaj duab xis.

2 resin particle melt index (MI) tsis tuaj yeem loj heev, yaj index (MI) loj dhau, ces yaj resin

Lub viscosity tsawg dhau, kev ua haujlwm yog nqaim, cov txheej txheem ua haujlwm tsis yooj yim los tswj, cov yeeb yaj kiab tsim cov cuab yeej ntawm cov resin tsis zoo, tsis yooj yim.

Kev ua yeeb yaj kiab;Tsis tas li ntawd, melt index (MI) loj dhau, polymer txheeb ze molecular phaus faib yog nqaim heev, nyias zaj duab xis

Yog tsis muaj zog.Yog li ntawd, ib qho me me yaj Performance index (MI) thiab qhov dav dua qhov txheeb ze molecular hnyav faib yuav tsum raug xaiv

Nws tuaj yeem ua tsis tau tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm cov yeeb yaj kiab, tab sis kuj xyuas kom meej cov yam ntxwv ntawm cov resin.

Tshuab moulded polyethylene zaj duab xis feem ntau siv cov yaj index (MI) nyob rau hauv thaj tsam ntawm 2 ~ 6g / 10min polyethylene

Cov khoom siv raw.
