PE hnab yas luv luv rau polyethylene.Nws yog ib qho thermoplastic resin polymerized los ntawm ethylene.Polyethylene tsis muaj ntxhiab tsw thiab zoo li siv quav ciab.Nws muaj qhov tsis zoo ntawm qhov kub thiab txias (tsis kub siv qhov kub thiab txias tuaj yeem ncav cuag -70 ~ -100 ℃), tshuaj lom neeg ruaj khov, tsis kam mus rau feem ntau cov kua qaub thiab cov hauv paus (tsis tiv taus oxidation acid), cov kuab tshuaj zoo tib yam hauv chav sov, nqus dej me me, zoo heev. hluav taws xob rwb thaiv tsev kev ua tau zoo.Kev kub siab polyethylene muaj qhov zoo ntawm qhov siab melting point, siab hardness, siab zog, tsis tshua muaj dej nqus, zoo hluav taws xob muaj nuj nqi, hluav taws xob siv hluav taws xob, siab cuam tshuam, qaug zog, hnav tsis kam, cuam tshuam tsis kam, corrosion kuj, siab elongation, siab cuam tshuam tsis kam. , toughness kuj, corrosion kuj thiab lwm yam.
Nws cov yam ntxwv yog raws li nram no:
1.Crystal cov ntaub ntawv, me me noo noo nqus, zoo fluidity, fluidity rhiab heev rau lub siab, molding yuav tsum tau siv lub siab txhaj tshuaj, uniform khoom kub, ceev filling ceev, txaus siab.
2.Wear tsis kam - muab kev tiv thaiv mus sij hawm ntev rau cov tsos ntawm ntau qhov kev ua haujlwm siab.
3.Impact resistance - Ua kom muaj kev ncaj ncees ntawm cov tsos hauv ntau daim ntawv thov uas qhov cuam tshuam tsis muaj zog.
4.Puncture kuj - tuaj yeem tsim ib qho nyuaj rau cov kua, kom nws tsis tuaj yeem corrode cov khoom.
5.Flexibility - hloov mus rau feem ntau cov duab.
6. Yooj yim rau siv - polyurethane muaj kev daws teeb meem rau ntau yam kev siv nruj.
7.Non-volatile tshuab Cheebtsam - Volatile tshuab Cheebtsam tsis tso tawm thaum siv.
PE hnab muaj kev tiv thaiv corrosion zoo heev, hluav taws xob rwb thaiv tsev (tshwj xeeb tshaj yog cov hluav taws xob ntau zaus), kev hloov tshuaj lom neeg, hloov hluav taws xob, tuaj yeem txhim kho cov iav fiber ntau.Nws muaj cov ntsiab lus melting tsawg, siab tawv, hardness thiab lub zog.Nws muaj peev xwm nqus dej me me.Tsis tshua muaj siab polyethylene muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob zoo, nrog cov softness, elongation, cuam tshuam lub zog thiab siab to taub, nrog rau lub zog muaj zog.Kev qaug zog thiab hnav tsis kam.Tsis tshua muaj siab polyethylene yog tsim rau kev tsim khoom ntawm corrosion resistant qhov chaw thiab rwb thaiv tsev qhov chaw;Kev kub siab polyethylene yog tsim los ua cov yeeb yaj kiab nyias.
