Alumina yog qhov tsim nyog rau ntau yam ntawm ntub thiab qhuav txheej txheem kho. Nws tuaj yeem zom cov ntxhib ntawm txhua qhov chaw ua haujlwm kom zoo. Nws yog ib qho ntawm cov pheej yig tshaj kev lag luam. Qhov zoo li no ntse thiab dej hauv siab lub zog hluavtaws abrasive muaj hardness thib ob rau pob zeb diamond, thiab yog qhov tshwj xeeb tshaj yog haum rau siv thaum muaj cov cai nruj rau cov pa phem hlau. Siv rau qhov txiav roughest, nws tseem tuaj yeem ua rau lub pob zeb zoo txhawm rau txhawm rau ua haujlwm precision-qhov loj qhov me kom ua tiav qhov tsis tshua muaj neeg. Vim tias nws lub cev ntom ntom, siab nrawm, thiab rhombohedral qauv, nws yog ib txoj haujlwm txiav nrawm dua.
Alumina yog siv los tsim cov xim av corundum los ntawm fusing high-zoo bauxite ore, thaum lub npe zoo aluminate yog siv los tsim cov hmoov corundum thiab corundum dawb. Lawv cov qauv siv lead ua ua rau lawv nyuaj thiab ceev. Nyob rau tib lub sijhawm, lawv feem ntau siv ua raw cov ntawv rau cov tsau thiab cov ua tsis zoo.
Alumina tuaj yeem rov ua dua tshiab ntau zaus, thiab tus lej ntawm cov xov tooj cuam tshuam nrog qib qib ntawm cov khoom thiab cov txheej txheem tshwj xeeb. Feem ntau txheem abrasive blasting cov khoom tuaj yeem siv.
Siv cov kev lag luam: kev lag luam aerospace, tsheb tsim kev lag luam, kev lag luam khoom siv khoom lag luam, cov khoom lag luam lag luam, cov khoom lag luam casting, tuag casting, OEM cov neeg xa khoom, kev lag luam semiconductor thiab lwm cov teb.
Cov txheej txheem muaj feem xyuam: nplaim electroplating, tha xim, kho qhov muag thiab pretreatment ua ntej PTFE txheej; deburring thiab lauj kaub scaling ntawm txhuas thiab alloy khoom; pwm tu; pretreatment ua ntej cov hlau sandblasting; qhuav sib tsoo thiab ntub dej sib tsoo; Precision optical refraction; kev sib tsoo ntawm cov zaub mov, cov hlau, iav thiab cov iav ci; iav carving thiab xim pleev xim ntxiv.
Qhib alumina
Kev ntsuas qhov ntsuas
Cov tsos mob ntawm cov tshuaj tiv thaiv alumina: ua kom muaj alumina yog dawb spherical ntxeem tau nrog cov khoom tawg me me, qhov chaw du, lub zog loj, muaj zog hygroscopicity, tsis o lossis tawg tom qab nqus dej, thiab tseem nyob, tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj ntxhiab dej hauv dej thiab ethanol, Nws muaj cov adsorption zoo rau cov tshuaj fluorine thiab feem ntau yog siv los tshem cov tshuaj fluoride hauv cov dej haus hauv thaj chaw uas muaj fluorine ntau.
Qhib alumina muaj kev xaiv adsorption muaj peev xwm rau roj, dej vapor thiab qee cov kua ua ya raws. Tom qab cov adsorption tsis txaus, nws tuaj yeem ua kom rov qab los ntawm cua kub ntawm thaj tsam ntawm 175-315 ° C kom tshem tawm cov dej. Cov ncauj lus tshaj tawm thiab kev sawv rov los muaj peev xwm ua tau ntau zaus. Ntxiv rau qhov raug siv los ua tus tshaj tawm, nws tseem tuaj yeem ua pa ntawm lub roj ntawm lubricating roj los ntawm cov pa paug, hydrogen, carbon dioxide, roj av, thiab lwm yam.
Kev siv alumina nyob rau qee qhov kev ua haujlwm thiab kev tsim kho tshiab, qhov ua kom qhuav ntawm qhov tob ntawm cov khoom yog raws li lub lwg taw tes kub-70 degrees lossis tsawg dua.
