Cov khoom siv dab tsi yog dawb corundum
Dawb corundum yog ib yam khoom siv siab purity alumina ceramic, uas kuj yog ib qho ntawm cov khoom siv ceramic nto moo hauv kev lag luam. Piv nrog rau cov ntaub ntawv ceramic zoo tib yam, corundum dawb muaj qhov zoo ntawm qhov tsis tshua muaj siab hardness, hnav tsis kam thiab tshuaj lom neeg ruaj khov. Yog li ntawd, nws yog dav siv nyob rau hauv ntau yam ntawm lub zog siab, siab hnav tsis kam thiab kub ib puag ncig, xws li aviation manufacturing, petrochemical kev lag luam, steelmaking, hluav taws xob technology thiab lwm yam.Qhov kev npaj ntawm dawb corundum yuav tsum muaj siab purity alumina, yog li nws yog nyuaj rau kev tsim khoom. Ua ntej, lub alumina yog finely hauv av thiab ces tov raws li ib tug tej yam kev faib ua feem thiab sintered nyob rau hauv high kub los ua ceramics nrog siab zog thiab hardness. Rau kev siv zoo tshaj plaws, nws kuj yuav tsum tau mus dhau qhov kev ua haujlwm siab kom ua tiav cov kev xav tau siab dua.Qhov hardness ntawm dawb corundum yuav luag zoo ib yam li cov hlau, ncav cuag Mohs hardness ntawm 9.0, uas yog qhov nyuaj tshaj. ntawm tag nrho cov ntaub ntawv ceramic tam sim no. Qhov no ua rau dawb corundum siv dav hauv kev lag luam, xws li nres, abrasives, abrasives, bearings, pneumatic seals thiab lwm yam. Nyob rau hauv cov hlau thiab hlau smelting, mechanical processing thiab lwm yam lag luam, dawb corundum tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv thiab txhim kho kev ua haujlwm ntau lawm. Tsis tas li ntawd, dawb corundum kuj muaj kev tiv thaiv corrosion siab heev, tuaj yeem hloov mus rau ntau yam. acidic, alkaline, kub thiab lwm yam hnyav ib puag ncig. Yog li ntawd, nyob rau hauv kev lag luam petrochemical, chemical engineering, electronics Cheebtsam thiab lwm yam kev lag luam, dawb corundum kuj tau lug siv, ua ib yam ntawm cov ntaub ntawv tseem ceeb.Nyob rau hauv luv luv, raws li ib yam ntawm high-kev ua tau zoo ceramic khoom, dawb corundum muaj cov yam ntxwv ntawm siab. hardness, muaj zog hnav tsis kam thiab zoo tshuaj stability, yog li nws muaj ntau yam ntawm daim ntawv thov kev cia siab nyob rau hauv kev lag luam teb. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov ntawm corundum dawb nyob rau hauv ntau yam kev lag luam yuav ntau thiab ntau dua, thiab nws tau ua ib qho tseem ceeb hauv kev txhim kho kev lag luam niaj hnub no.
