POE yog dab tsi? In-depth tsom xam ntawm nws cov khoom thiab kev siv
POE (Polyolefin Elastomer) yog cov khoom siv polymer dav siv hauv kev lag luam tshuaj nyob rau xyoo tas los no. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev xav tau ntawm kev lag luam, POE ua tau zoo hauv ntau qhov chaw vim nws cov khoom tshwj xeeb. Hauv tsab xov xwm no, peb yuav tham txog qhov nthuav dav POE yog dab tsi, thiab txheeb xyuas nws cov khoom, txheej txheem tsim khoom thiab cov chaw siv los pab cov neeg nyeem kom nkag siab zoo txog tus nqi ntawm cov khoom siv no.
Basic Properties of POE
POE khoom yog dab tsi? Hais txog cov qauv tshuaj, POE yog ib qho elastomer ua los ntawm copolymerisation ntawm ethylene nrog ib tug copolymerising monomer, feem ntau yog α-olefin. Nws cov khoom tseem ceeb muaj xws li elasticity zoo heev, tsis tshua muaj ntom, siab transparency, thiab huab cua zoo thiab kub tsis kam. Nws yog cov khoom no uas tso cai rau POE ua tau zoo nyob rau hauv ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv tsheb, ntim khoom thiab cable sheathing.
POE Production Process
Yuav kom nkag siab tias POE yog dab tsi, nws yog ib qho tseem ceeb uas yuav tsum tau saib cov txheej txheem uas nws tsim, uas feem ntau yog los ntawm metallocene catalyst polymerization. Metallocene catalysts yog cov reactive catalysts uas tso cai rau kev tswj kom meej ntawm qhov hnyav molecular faib ntawm cov polymer thiab embedding ntawm copolymer monomers. Cov txheej txheem no ua rau muaj kev ua tau zoo heev thiab cov khoom zoo ib yam rau ntau hom kev ua haujlwm xws li txhaj tshuaj, extrusion thiab tshuab moulding.
Cov chaw siv tseem ceeb ntawm POE
Thaum koj paub tias POE yog dab tsi, kev nkag siab txog nws qhov chaw thov yog qhov tseem ceeb rau kev nkag siab tag nrho ntawm cov khoom. Vim nws elasticity thiab durability, POE yog siv nyob rau hauv ib tug ntau yam ntawm automotive daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv lub tsheb ntsaws ruaj ruaj, bumpers thiab sab hauv cov ntaub ntawv.POE qhov tsawg ntom thiab pob tshab ua rau nws zoo tagnrho rau cov khoom ntim zoo, xws li cov khoom ntim zaj duab xis. Cable sheathing cov ntaub ntawv kuj yog ib qho tseem ceeb daim ntawv thov cheeb tsam rau POE. Nrog nws cov huab cua zoo thiab tsis kub tsis kam, POE tuaj yeem ua haujlwm tau zoo rau kev pab cuam lub neej ntawm cables.
POE vs lwm elastomers
Txhawm rau kom nkag siab zoo dua POE yog dab tsi, peb tuaj yeem muab piv rau lwm cov elastomers xws li TPU (thermoplastic polyurethane) thiab EPDM (ethylene propylene diene roj hmab), uas muaj qis dua, kev ua tau zoo thiab cov nqi qis. Thiab piv rau EPDM, POE ua tau zoo dua nyob rau hauv cov nqe lus ntawm qhov kub thiab txias kev ua tau zoo thiab pob tshab. Yog li ntawd, POE feem ntau yog siv los ua lwm yam khoom siv los txhim kho cov khoom ua tau zoo thiab txo cov nqi.
Cov ntsiab lus
POE yog dab tsi? Cias muab, POE yog cov khoom siv elastomeric ua haujlwm siab nrog ntau yam kev siv. Ua tsaug rau nws cov khoom tshwj xeeb, xws li nrawm nrawm, qis dua thiab cov txheej txheem zoo tshaj plaws, poe qhia tau muaj peev xwm loj nyob hauv ntau thaj chaw. Txawm hais tias hauv kev lag luam tsheb, kev lag luam ntim khoom, lossis kev tsim khoom siv cable, POE qhib qhov muaj peev xwm tshiab hauv cov ntaub ntawv tshawb fawb thiab engineering.
Vam tias, los ntawm cov kab lus no, cov neeg nyeem yuav nkag siab meej txog qhov POE yog dab tsi thiab vim li cas nws thiaj li nyob hauv qhov chaw tseem ceeb hauv kev lag luam tshuaj.
