Low Density Polyethylene Cov Khoom Siv Ua Haujlwm

Cov yam ntxwv ntawm low-density polyethylene yog raws li nram no

1. Zaj duab xis yog me ntsis milky dawb pob tshab thiab mos. Lub zog yog me dua li ntawm high-density polyethylene, thiab qhov cuam tshuam lub zog yog ntau dua li ntawm high-density polyethylene.

2. Txias tsis kam, tsis kub tsis kam thiab kub tsis kam. Lub thicker zaj duab xis tuaj yeem tiv taus cov txheej txheem kom tsis muaj menyuam hauv dej kub ntawm 90 degree.

3. Zoo noo noo-pov thawj kev ua tau zoo, ruaj khov tshuaj, insoluble nyob rau hauv cov kuab tshuaj.

4. Nws muaj huab cua permeability ntau dua, yog li thaum siv cov ntim khoom noj oxidized, lub sij hawm cia ntawm nws cov ntsiab lus yuav tsum tsis txhob ntev dhau.

5. Cov roj kuj tsis zoo, thiab cov khoom yuav maj mam yaj. Thaum ntim cov khoom noj uas muaj roj, nws yuav ua rau cov zaub mov muaj lub saj hala tom qab lub sijhawm ntev cia.

6. Ntev mus ntev rau ultraviolet rays thiab tshav kub yuav muaj hnub nyoog, cuam tshuam nws lub cev thiab dielectric zog.

7. Lub melting point yog 110 ~ 115 degree, qhov kub ua hauj lwm yog 150 ~ 210 degree, yog hais tias nyob rau hauv lub inert roj, qhov kub yuav ncav cuag 300 degree yog tseem ruaj khov. Txawm li cas los xij, kev sib cuag nrog cov yaj thiab oxygen yog qhov ua rau degradation.
