(1) Taw qhia rau cov ntaub ntawv POM
Qhov zoo:
High rigidity, siab zog, thiab ruaj khov mechanical zog;
Creep kuj, qaug zog tsis kam, siab elastic modulus;
Kev sib txhuam thiab hnav tsis kam, nws tus kheej lubricating zog;
Resistant rau 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 txaus:
Tsis zoo thermal stability, cov khoom yog ib qho yooj yim rau decompose ntawm qhov kub thiab txias;
High crystallinity, loj molding shrinkage;
Tsis tshua muaj kev cuam tshuam;
Tsis resistant rau muaj zog acid thiab alkali.
(2) Kev siv POM hauv kev ua haujlwm tsheb
Kev lag luam tsheb yog lub lag luam loj tshaj plaws rau POM.POM yog lub teeb hauv qhov hnyav, tsis tshua muaj suab nrov, yooj yim hauv kev ua thiab molding, thiab tsawg tus nqi tsim khoom.Nws tuaj yeem siv dav hauv tsheb raws li kev hloov pauv rau qee cov hlau, thiab ua tau raws li kev txhim kho ntawm lub tsheb sib zog.
Kev hloov kho POM muaj kev sib txhuam coefficient tsawg, hnav tsis kam thiab muaj zog rigidity, uas yog qhov tsim nyog rau kev tsim cov tsheb sib kis thiab qhov chaw ua haujlwm.
