Ua ib lub yas engineering kub uas muaj cov khoom muaj zog heev nyob rau xyoo tas los no, POM board tau siv dav hauv kev lag luam kev tsim kho thiab kev lag luam tsim khoom. Ib txhia neeg txawm xav tias POM board tuaj yeem hloov cov khoom siv hlau xws li hlau, zinc, tooj liab thiab txhuas. Vim tias POM board yog ib lub thermoplastic engineering plastic nrog lub ntsiab lus melting siab thiab crystallinity siab, nws yuav tsum tau hloov kho thiab txhim kho thaum nws siv rau hauv ntau qhov xwm txheej thov.
Cov khoom siv POM muaj cov yam ntxwv ntawm kev tawv siab, kev tiv thaiv kev hnav, kev tiv thaiv dej noo, kev tiv thaiv tshuaj lom neeg, thiab lwm yam. Nws muaj kev tiv thaiv roj zoo, kev tiv thaiv kev qaug zog, lub zog cuam tshuam siab, kev tawv siab, kev tiv thaiv nkag siab, kev ruaj khov zoo, kev ua kom nws tus kheej lubricating, Nws muaj kev ywj pheej tsim qauv siab thiab tuaj yeem siv tau ntev ntawm -40 txog 100 ° C. Txawm li cas los xij, vim muaj qhov ceev ceev, lub zog cuam tshuam notched qis, kev tiv thaiv cua sov tsis zoo, nws tsis haum rau hluav taws kub retardant, nws tsis haum rau kev luam ntawv, thiab tus nqi molding shrinkage loj, yog li POM kev hloov kho yog qhov kev xaiv tsis zam. POM yooj yim heev rau crystallize thaum lub sijhawm tsim thiab tsim cov spherulites loj dua. Thaum cov khoom raug cuam tshuam, cov spherulites loj dua no feem ntau tsim cov ntsiab lus ntxhov siab thiab ua rau cov khoom puas tsuaj.
POM muaj qhov rhiab heev ntawm qhov tsis sib xws, lub zog cuam tshuam qis, thiab qhov nrawm ntawm kev txhaj tshuaj molding siab. Cov khoom no yooj yim raug kev ntxhov siab sab hauv thiab nyuaj rau tsim kom nruj. Qhov no txwv tsis pub siv POM ntau thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam hauv qee yam. Yog li ntawd, txhawm rau kom hloov kho tau zoo dua rau qhov chaw ua haujlwm hnyav xws li kev kub ceev, kev kub siab, kub siab, thiab kev thauj khoom siab, thiab nthuav dav ntxiv ntawm kev siv POM, nws yog qhov tsim nyog los txhim kho qhov tawv ntawm kev cuam tshuam, kev tiv taus cua sov thiab kev sib txhuam ntawm POM.
Tus yuam sij rau kev hloov kho ntawm POM yog qhov sib xws ntawm cov theem ntawm lub kaw lus sib xyaw, thiab kev txhim kho thiab kev tshawb fawb ntawm cov khoom sib xws ntau yam yuav tsum tau nce ntxiv. Lub kaw lus gel tshiab tsim thiab hauv-situ polymerized ionomer toughening ua rau lub kaw lus sib xyaw tsim ib lub network interpenetrating ruaj khov, uas yog ib qho kev tshawb fawb tshiab los daws qhov kev sib xws interphase. Tus yuam sij rau kev hloov kho tshuaj lom neeg nyob rau hauv kev qhia txog cov pab pawg ntau yam rau hauv cov saw hlau molecular los ntawm kev xaiv comonomers thaum lub sijhawm synthesis los muab cov xwm txheej rau kev hloov kho ntxiv; kho tus lej ntawm comonomers, optimizing tsim ntawm cov qauv molecular, thiab synthesizing serialization thiab functionalization thiab high-performance POM.
