Raws li cov khoom siv hluav taws xob kub kub nrog cov khoom muaj zog hauv xyoo tas los no, POM board tau siv dav hauv kev tsim kho thiab kev lag luam.Qee tus neeg txawm xav tias POM board tuaj yeem hloov cov khoom siv hlau xws li hlau, zinc, tooj liab thiab txhuas.Txij li thaum POM lub rooj tsavxwm yog ib qho thermoplastic engineering yas nrog lub siab melting point thiab siab crystallinity, nws yuav tsum tau hloov kho thiab hloov kho dua tshiab thaum nws siv nyob rau hauv ntau daim ntawv thov scenarios.
Cov khoom siv POM muaj cov yam ntxwv ntawm kev ua haujlwm siab, hnav tsis kam, noo noo tsis kam, tshuaj lom neeg ua haujlwm, thiab lwm yam. Nws muaj cov roj tsis muaj zog, qaug zog ua haujlwm, muaj zog muaj zog, siab toughness, siab creep resistance, zoo dimensional stability, nws tus kheej lubricating, nws muaj ib tug high degree ntawm kev ywj pheej tsim thiab yuav siv tau rau lub sij hawm ntev ntawm -40 mus rau 100 ° C.Txawm li cas los xij, vim muaj qhov sib txawv ntawm cov txheeb ze siab, qhov kev cuam tshuam ntawm lub zog tsis tshua muaj, cov cua sov tsis zoo, nws tsis haum rau cov nplaim hluav taws, nws tsis haum rau kev luam ntawv, thiab cov molding shrinkage tus nqi yog qhov loj, yog li POM hloov kho yog ib qho zoo heev. kev xaiv tsis tau.POM yooj yim heev rau crystallize thaum lub sij hawm tsim cov txheej txheem thiab tsim cov spherulites loj.Thaum cov khoom raug cuam tshuam, cov spherulites loj dua no yooj yim tsim cov ntsiab lus kev ntxhov siab thiab ua rau cov khoom puas tsuaj.
POM muaj siab rhiab heev, tsis tshua muaj kev cuam tshuam lub zog, thiab siab molding shrinkage tus nqi.Cov khoom yog ua rau kev ntxhov siab sab hauv thiab yog qhov nyuaj rau tsim kom nruj.Qhov no txwv tsis pub siv ntau yam ntawm POM thiab tsis tuaj yeem ua tau raws li kev lag luam hauv qee yam.Yog li ntawd, txhawm rau hloov kho kom zoo dua rau qhov chaw ua haujlwm hnyav xws li kev kub ceev, kev kub siab, kev kub siab, thiab kev thauj khoom siab, thiab txuas ntxiv nthuav dav daim ntawv thov ntawm POM, nws yog ib qho tsim nyog los txhim kho qhov cuam tshuam toughness, kub tsis kam thiab kev sib txhuam. of POM.
Tus yuam sij rau kev hloov kho ntawm POM yog qhov sib xyaw ua ke ntawm cov theem ntawm kev sib xyaw ua ke, thiab kev txhim kho thiab kev tshawb fawb ntawm multifunctional compatibilizers yuav tsum tau nce.Cov txheej txheem tshiab tsim gel thiab hauv-situ polymerized ionomer toughening ua rau cov txheej txheem sib xyaw ua kom muaj kev sib txuam ruaj khov, uas yog cov kev tshawb fawb tshiab los daws cov kev sib raug zoo ntawm interphase.Tus yuam sij rau kev hloov kho tshuaj yog nyob rau hauv kev taw qhia ntawm ntau pab pawg rau hauv cov saw hlau molecular los ntawm kev xaiv cov comonomers thaum lub sij hawm tsim cov txheej txheem los muab cov xwm txheej rau kev hloov kho ntxiv;kho tus naj npawb ntawm comonomers, optimizing tus tsim ntawm molecular qauv, thiab synthesizing serialization thiab functionalization thiab high-performance POM.
