Polyoxymethylene (POM) yog ib hom linear polymer yam tsis muaj sab saw, nrog siab ceev thiab siab crystallinity, uas muaj cov khoom zoo heev.Qhov zoo tshaj plaws yam ntxwv ntawm cov khoom no yog nws cov elastic modulus siab, siab hardness thiab rigidity.
POM yog cov yas crystalline nrog zoo fluidity nyob rau hauv lub xeev molten.Nws pom tseeb viscosity feem ntau cuam tshuam los ntawm tus nqi shear.Nws yog cov khoom siv shear rhiab heev,
Raws li cov qauv tshuaj sib txawv ntawm cov saw hlau molecular, polyoxymethylene tuaj yeem muab faib ua homopolymerization thiab copolymerization.Lub homopolymer muaj siab ceev, crystallinity thiab txhua yam muaj zog, thaum lub copolymer muaj zoo thermal stability, molding processability thiab acid thiab alkaline kuj.
Kev siv POM
1. Cov iav kis tau yooj yim, lub tes tsho qhia, cov khoom ua si lub cev muaj zog, ntsuas iav.
2. POM yog qhov tsim nyog rau kev tsim cov twj tso kua mis, carburetor qhov chaw, roj kav dej, lub hwj chim li qub, sab sauv kaum txhiab bearings, lub cev muaj zog, cranks, tes tuav, dashboard, qhov rais lifter li, hluav taws xob hloov, kev nyab xeeb siv buckles, thiab lwm yam rau tsheb.Kev tsim cov khoom hnav-tiv taus xws li lub tes tsho ncej, iav thiab zawv zawg thaiv yog lub zog ntawm kev hloov kho POM.Cov khoom no muaj tsawg hnav ntawm cov hlau, txo cov roj lubricating, thiab txhim khu lub neej kev pab cuam ntawm qhov chaw.Yog li ntawd, lawv tuaj yeem hloov tau tooj liab, zinc thiab lwm yam hlau los tsim cov bearings, zog, rub rods, thiab lwm yam.
