Product Description
Tsawg Density Polyethylene LDPE
Tsawg-density polyethylene (LDPE) yog cov khoom siv hluavtaws siv cov txheej txheem siab ntawm cov dawb radical polymerization ntawm ethylene thiab yog li ntawd kuj 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, zoo heev hluav taws xob rwb thaiv tsev zog. 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.

3. Daim ntawv thov ntawm LDPE
1. LDPE feem ntau yog siv los ua cov yeeb yaj kiab. Nws yog dav siv nyob rau hauv zus tau tej cov
- zaj duab xis ua liaj ua teb (mulching zaj duab xis thiab tso zaj duab xis),
- ntim zaj duab xis (rau siv ntim khoom qab zib, zaub thiab zaub mov khov),
- tshuab zaj duab xis rau ntim kua (rau siv ntim mis, soy sauce, kua txiv hmab txiv ntoo, taum curds thiab kua mis),
- cov hnab ntim khoom hnyav,
- shrinkage ntim zaj duab xis,
- elastic zaj duab xis,
- zaj duab xis,
- siv films,
- general-purpose industrial ntim zaj duab xis thiab cov hnab ntim khoom noj.
2. 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.
3. 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.
4. LDPE kuj tseem siv tau los ua cov khoom siv molded hollow xws li cov thawv ntim khoom noj, tshuaj, tshuaj pleev ib ce thiab cov khoom siv tshuaj, thiab lub tank.
