Tshawb xyuas qhov zoo thiab qhov tsis zoo ntawm cov hlau ua los ntawm cov hlau polyurethane casters

Hlau core polyurethane caster yog ib hom caster nrog cov khoom siv polyurethane, sib txuas rau cam khwb cia hlau core, steel core lossis steel phaj core, uas yog ntsiag to, qeeb hnyav thiab pheej yig, thiab yog qhov tsim nyog rau feem ntau qhov chaw ua haujlwm.
Feem ntau, qhov loj ntawm cov log tsheb thauj khoom siv hauv kev lag luam yog nruab nrab ntawm 4 ~ 8 nti (100-200 hli), nrog rau lub log polyurethane yog qhov zoo tshaj plaws. Lub log polyurethane muaj kev tiv thaiv kev sib txhuam zoo, ntau yam kev ua tau zoo hloov kho tau, ntau txoj kev ua tiav, siv tau dav, thiab tiv taus roj, ozone, laus, hluav taws xob, kub qis, thiab lwm yam, suab zoo permeability, muaj zog nplaum zoo, biocompatibility zoo heev thiab sib xws nrog cov ntshav.

Cov casters polyurethane feem ntau yog cov yam ntxwv hauv qab no:
1. Muaj ntau yam kev ua tau zoo uas hloov tau. Los ntawm kev xaiv cov khoom siv raw thiab kho cov mis, nws tuaj yeem hloov pauv tau raws li qhov xav tau ntawm ntau yam kev ua tau zoo ntawm lub cev thiab lub tshuab, kom ua tau raws li qhov xav tau ntawm tus neeg siv ntawm kev ua tau zoo ntawm cov khoom. Piv txwv li, polyurethane elastomers tuaj yeem ua rau cov roj hmab luam ntawv mos thiab cov hlau tawv kom ua tau raws li qhov xav tau ntawm cov neeg siv sib txawv.
2. Kev tiv thaiv kev puas tsuaj zoo heev. Thaum muaj dej, roj thiab lwm yam kev ua haujlwm ntawm cov khoom siv ntub dej, qhov kev tiv thaiv kev hnav ntawm cov polyurethane casters yog ntau zaus txog ntau zaus ntawm cov khoom siv roj hmab ib txwm muaj.

3. Muaj ntau txoj kev ua thiab siv tau dav. Polyurethane elastomer tuaj yeem pwm los ntawm kev ua yas, sib tov thiab vulcanizing (hais txog MPU); nws kuj tuaj yeem ua rau roj hmab ua kua, casting molding lossis txau, potting thiab centrifugal molding (hais txog CPU); nws kuj tuaj yeem ua rau cov khoom siv granular thiab pwm los ntawm kev txhaj tshuaj, extrusion, calendering, blow molding thiab lwm yam txheej txheem (hais txog CPU).
4. Tiv taus roj, ozone, laus, hluav taws xob, kub qis, suab kis tau zoo, muaj zog nplaum, biocompatibility zoo heev thiab ntshav sib xws.

Txawm li cas los xij, polyurethane elastomers muaj qee qhov tsis zoo, xws li cua sov endogenous siab, kub siab tiv taus feem ntau, tshwj xeeb tshaj yog tsis kam rau noo noo thiab cua sov, tsis tiv taus cov kuab tshuaj polar muaj zog thiab cov kua qaub thiab alkali muaj zog.
