Dab tsi yog txhuas oxide siv rau?
Alumina (al2o3)Ua haujlwm ua cov khoom siv raw rau ntau yam ntawm cov khoom lag luam tshaj lij sib xyaw ua ke, nrog rau cov adsorbents, xws li cov tshuaj yeeb yaj kiab, tshuaj ntsuab, kev lag luam AERPACACE, thiab lwm qhov chaw siab. Cov yam ntxwv zoo tshaj plaws Alumina tuaj yeem muab ua kom nws zoo rau siv nyob rau hauv ntau daim ntawv thov. Qee cov ntawv thov feem ntau nyob sab nraud ntawm Aluminium ntau lawm muaj nyob hauv qab no. Fillers. Ua kom ncaj ncees chemically inert thiab dawb, txhuas oxide yog ib qho kev nyiam muab tub lim rau plastics. Iav.many ntawm cov iav muaj txhuas oxide ua cov khoom xyaw. Cataly; oxide Catalyses muaj ntau yam ntawm cov tshuaj tiv thaiv uas muaj txiaj ntsig kev ua haujlwm. Roj sam roj. Aluminium Oxide yog dav siv los tshem tawm cov dej los ntawm kwj ntws. Abrasive. Txhuas oxide yog siv rau nws lub hardness thiab lub zog. Xim. Aluminium oxide flakes yog siv rau hauv cov xim pleev xim rau kev ua kom zoo nkauj. Composite fiber ntau. Txhuas xide tau siv hauv ob peb sim thiab ua lag luam rau cov ntawv thov kev ua tau zoo (piv txwv li Fiber ntau 610, Nextel 720). Lub cev armor.some lub cev armors Puas muaj kev tiv thaiv. Txhuas oxide tuaj yeem cog ua cov txheej xim rau txhuas los ntawm anodizing lossis los ntawm Plasma Electrolytic oxidation. Kev Rwb Hluav Taws Xob Hluav Taws Xob. Txhuas oxide yog cov tshuaj tiv thaiv hluav taws xob siv ua ib qho sapphire (silication)
Txhuas Oxide, Ua ib tug dielectric nrog cov qhab sib txuas loj loj, yog siv los ua cov thaiv kev insulating hauv capacitors. Hauv kev teeb pom kev zoo, translulucent txhuas olide yog siv nyob rau hauv qee cov teeb ci ntsa iab. Txhuas Oxide tseem siv nyob rau hauv kev npaj ntawm kev ncua kev ncua hauv kev sib xyaw cov roj fluorescent teeb. Hauv Chemistry Chaw soj ntsuam chaw soj nstists, aluminium oxide yog qhov nruab nrab rau cov medomaph rau cov tshuaj chromatography, muaj nyob rau hauv theem pib (ph idicic (pH 4.5 thaum nyob hauv dej) thiab kev sib tw. Cov ntawv thov kev noj qab haus huv thiab kev kho mob muaj xws li nws cov khoom hauv kev hloov pauv ntawm lub duav thiab cov tshuaj tswj kev tswj hwm. Nws yog siv los ua scintillator thiab lub npog rau kev tiv thaiv hluavtaws thiab kho cov ntaub ntawv rau nws cov khoom siv ua kom pom kev zoo nkauj. Rwb thaiv tsev rau kev ua kom sov sov yog feem ntau tsim los ntawm txhuas oxide. Cov ntawv me me ntawm txhuas oxide feem ntau siv los ua cov nqaij npau npau hauv chemical. Nws tseem siv los ua rau lub ntsaws cov insulators. Siv cov tshuaj txau ntshav ua kom zoo thiab sib xyaw nrog titania, nws yog co rau ntawm lub braking saum npoo ntawm qee lub tsheb kauj vab rims kom muaj kev puas tsuaj thiab hnav tsis kam. Feem ntau cov lus sib xyaw ntawm cov pas nuv ntses yog cov nplhaib sib ncig ua los ntawm txhuas oxide. Hauv nws cov hmoov zoo tshaj plaws (dawb) daim ntawv, hu ua diamantine, txhuas oxide yog siv los ua cov muaj kev sib txawv hauv kev saib xyuas thiab moos. Txhuas oxide tseem siv nyob rau hauv txheej txheej ntawm stanchions hauv lub cev muaj zog hla thiab roob tsheb tuam kev lag luam. Cov txheej no ua ke nrog molybdenum disulfate muab lub sijhawm ntev lubrication ntawm lub npoo.
