Polyurethane (PU), lub npe tag nrho ntawm polyurethane, yog cov khoom siv polymer, uas tau tsim xyoo 1937 los ntawm Otto Bayer thiab lwm tus. Polyurethane muaj ob pawg tseem ceeb: polyester thiab polyether. Lawv tuaj yeem ua rau hauv cov yas polyurethane (feem ntau ua npuas ncauj), polyurethane fibers (paub tias yog spandex hauv Suav teb), polyurethane roj hmab thiab elastomers. Polyurethane yog cov khoom siv polymer uas zoo tagnrho rau siv los ua lub log npog hauv kev tsim cov casters.
Lub ntsiab zoo ntawm polyurethane casters yog raws li nram no:
Ua ntej, qhov kev ua tau zoo ntawm qhov adjustable ntau yam
Ib tug xov tooj ntawm lub cev thiab cov neeg kho tshuab kev ua tau zoo ntsuas yuav raug kho los ntawm kev xaiv ntawm raw cov ntaub ntawv thiab cov qauv, nyob rau hauv ib tug tej yam ntau yam ntawm saj zawg zog hloov, thiaj li ua tau raws li cov neeg siv qhov tshwj xeeb yuav tsum tau rau cov khoom ua tau zoo.
Thib ob, superior abrasion kuj
Nyob rau hauv lub xub ntiag ntawm dej, roj thiab lwm yam wetting xov xwm ua hauj lwm tej yam kev mob, polyurethane casters hnav tsis kam yog feem ntau ob peb zaug mus rau kaum ob lub sij hawm ntawm cov khoom siv roj hmab zoo tib yam. Cov ntaub ntawv hlau xws li hlau thiab lwm yam tawv, tab sis tsis tas yuav hnav-tiv taus!
Thib peb, txheej txheem txheej txheem, dav siv tau
Polyurethane elastomers tuaj yeem ua pwm nrog cov roj hmab dav dav los ntawm plasticizing, sib xyaw thiab vulcanizing (MPU); lawv kuj tuaj yeem ua rau cov roj hmab ua kua, nchuav thiab molding lossis txau, sealing thiab centrifugal molding (CPU); lawv tuaj yeem ua rau cov ntaub ntawv granular thiab cov yas zoo tib yam los ntawm kev txhaj tshuaj, extrusion, calendering, tshuab molding thiab lwm yam txheej txheem (CPU). Pwm los yog txhaj tshuaj molded qhov chaw, nyob rau hauv ib tug tej yam hardness ntau yam, kuj yuav txiav, sib tsoo, drilling thiab lwm yam mechanical ua.
Plaub, roj kuj, ozone kuj, kev laus tsis kam, hluav taws xob tsis kam, tsis kub tsis kam, zoo suab kis tau tus mob, muaj zog nplaum quab yuam, zoo heev biocompatibility thiab ntshav compatibility. Cov txiaj ntsig zoo no yog vim li cas vim li cas polyurethane elastomers tau dav siv hauv tub rog, aerospace, acoustics, biology thiab lwm yam haujlwm.
