(1) Kev Taw Qhia Txog Cov Khoom Siv POM
Qhov Zoo:
Kev ruaj khov siab, lub zog siab, thiab cov khoom siv kho tshuab ruaj khov;
Kev tiv thaiv kev qaug zog, kev qaug zog tsis kam, siab elastic modulus;
Kev sib txhuam thiab kev hnav tsis kam, cov khoom siv lubricating tus kheej;
Tiv taus cov tshuaj inorganic thiab ntau yam roj;
Zoo nkauj nto, siab gloss, yooj yim rau daim ntawv;
Haum rau kev ntxig molding, txhaj tshuaj molding thiab txiav ntawm cov hlau ntxig, vuam, thiab lwm yam.
Qhov Tsis Zoo:
Tsis ruaj khov thermal, cov khoom siv yooj yim rau decompose ntawm qhov kub siab;
Muaj crystallinity siab, molding shrinkage loj;
Kev cuam tshuam qis;
Tsis kam rau cov kua qaub thiab alkali muaj zog.
(2) Kev siv POM hauv kev lag luam tsheb
Kev lag luam tsheb yog lub khw loj tshaj plaws rau POM. POM yog lub teeb yuag, suab nrov tsawg, yooj yim ua thiab pwm, thiab tus nqi tsim khoom qis. Nws tuaj yeem siv dav hauv tsheb hloov qee cov hlau, thiab ua tau raws li kev coj ua ntawm lub tsheb sib dua.
Cov POM hloov kho muaj cov coefficient sib txhuam tsawg, tsis kam hnav thiab muaj zog rigidity, uas yog qhov tsim nyog rau kev tsim cov khoom sib kis tsheb thiab cov khoom ua haujlwm.
