Lub hnab yas PE yog luv rau polyethylene. Nws yog ib hom thermoplastic resin polymerized los ntawm ethylene. Polyethylene tsis muaj ntxhiab thiab zoo li quav ciab. Nws muaj kev tiv taus kub qis zoo heev (qhov kub qis siv tau txog -70 ~ -100 ℃), ruaj khov tshuaj zoo, tiv taus feem ntau cov kua qaub thiab cov hauv paus (tsis tiv taus oxidation acid), cov kuab tshuaj ib txwm nyob rau hauv chav tsev kub, nqus dej me me, ua haujlwm hluav taws xob zoo heev. Polyethylene siab muaj qhov zoo ntawm qhov melting point siab, hardness siab, muaj zog siab, nqus dej tsawg, ua haujlwm hluav taws xob zoo, muaj zog hluav taws xob siab, tiv taus kev cuam tshuam siab, qaug zog, tiv taus hnav, tiv taus kev cuam tshuam, tiv taus corrosion, elongation siab, tiv taus kev cuam tshuam siab, tiv taus to, tiv taus corrosion thiab lwm yam.
Nws cov yam ntxwv yog raws li nram no:
1. Cov khoom siv siv lead ua, kev nqus dej me me, cov kua dej zoo, cov kua dej rhiab rau qhov siab, molding yuav tsum siv kev txhaj tshuaj siab, cov khoom siv kub sib xws, kev sau ceev ceev, siab txaus.
2. Hnav tsis kam - muab kev tiv thaiv mus sij hawm ntev rau qhov pom ntawm ntau yam kev ua haujlwm siab.
3. Kev cuam tshuam tsis kam - Tswj kom muaj kev ncaj ncees ntawm qhov tsos hauv ntau daim ntawv thov uas qhov cuam tshuam tsis muaj zog.
4. Kev tiv thaiv kev tho - tuaj yeem tsim ib qho teeb meem nyuaj rau cov kua, yog li nws tsis tuaj yeem ua rau cov khoom puas.
5. Kev yooj ywm - hloov kho rau feem ntau ntawm cov duab nto.
6. Yooj yim siv - polyurethane muab kev daws teeb meem rau ntau yam kev siv hnyav.
7. Cov khoom siv tshuab tsis hloov pauv - Cov khoom siv tshuab hloov pauv tsis raug tso tawm thaum siv.
Lub hnab PE muaj kev tiv thaiv xeb zoo heev, hluav taws xob rwb thaiv tsev (tshwj xeeb tshaj yog kev rwb thaiv tsev zaus siab), kev hloov kho tshuaj lom neeg, kev hloov kho radioactive, tuaj yeem txhim kho cov iav fiber. Nws muaj qhov chaw yaj qis, siab tawv, tawv thiab lub zog. Nws lub peev xwm nqus dej me me. Polyethylene qis siab muaj cov khoom hluav taws xob zoo thiab radioactive, nrog rau mos, elongation, lub zog cuam tshuam thiab tus nqi xau siab, nrog rau lub zog cuam tshuam siab. Kev qaug zog thiab kev hnav tsis kam. Polyethylene qis siab yog qhov tsim nyog rau kev tsim cov khoom tiv thaiv corrosion thiab cov khoom rwb thaiv tsev; Polyethylene siab siab yog qhov tsim nyog rau kev ua cov zaj duab xis nyias.
