Nyob rau hauv lub tshav pob ntawm cov ntaub ntawv refractory, corundum, raws li ib tug tseem ceeb raw khoom, tau los ua ib tug dav siv cov ntaub ntawv nyob rau hauv lub refractory kev lag luam vim nws zoo heev lub cev thiab tshuaj zog. Tsab ntawv xov xwm no yuav qhia txog cov yam ntxwv tseem ceeb, kev siv dav, kev ua lag luam, thiab cov txheej txheem tsim khoom ntawm corundum kom ntxaws, thiab tsom mus rau 200-mesh corundum high-efficiency sib tsoo tshuab qhia rau koj seb nws ua rau lub sijhawm tshiab ntawm kev sib tsoo zoo.

Corundum yog lub pov haum tsim los ntawm crystallization ntawm aluminium oxide. Nws hardness yog thib ob tsuas yog pob zeb diamond thiab cubic boron nitride, thiab nws cov Mohs hardness ncav cuag 9. Lub npe ntawm corundum originated los ntawm Is Nrias teb. Nws cov khoom tseem ceeb yog Al₂O₃, thiab muaj peb qhov sib txawv: α-Al₂O₃, β-Al₂O₃, γ-Al₂O₃. Vim nws lub cev zoo heev, corundum yog siv dav hauv kev sib tsoo cov ntaub ntawv, watches, bearing cov ntaub ntawv rau precision machinery, thiab lwm yam teb.

Kev siv corundum

Daim ntawv thov ntau yam ntawm corundum yog dav heev, npog ntau yam kev lag luam xws li metallurgy, machinery, tshuaj lom neeg kev lag luam, electronics, aviation, thiab lub teb chaws tiv thaiv. Vim nws qhov kub thiab txias tsis kam, corrosion kuj, thiab siab zog, corundum yog siv los ua crucible thiab nkoj rau casting steel zawv zawg qhov rooj, smelting tsawg precious hlau, thiab tshwj xeeb alloys; nyob rau hauv cov tshuaj siv tshuaj, corundum yog siv los ua ntau yam tshuaj tiv thaiv cov hlab ntsha thiab cov kav dej thiab cov tshuaj twj tso kua mis; nyob rau hauv cov khoom siv kho tshuab, corundum yog siv los ua riam, pwm, cov ntaub ntawv mos mos, thiab lwm yam. Tsis tas li ntawd, cov khoom pob tshab corundum kuj tseem siv tau los ua cov teeb thiab microwave fairings, thiab Na-b-Al₂O₃ cov khoom yog cov khoom siv electrolyte rau kev ua cov roj teeb sodium-sulfur.

Corundum Market Situation

Nyob rau hauv xyoo tas los no, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev loj hlob sai ntawm kev lag luam, qhov kev thov rau corundum tau txuas ntxiv mus, thiab kev lag luam kev cia siab yog dav. Tuam Tshoj, Is Nrias teb, thiab Brazil yog lub ntiaj teb cov neeg tsim khoom loj tshaj plaws corundum, ntawm cov uas Tuam Tshoj yog lub ntiaj teb cov neeg tsim khoom loj tshaj plaws thiab xa tawm dawb corundum. Kev ua lag luam corundum nthuav tawm lub xeev ntawm kev sib npaug ntawm cov khoom siv thiab kev xav tau, nrog rau cov khoom lag luam zoo txuas ntxiv txhim kho thiab daim ntawv thov thaj chaw txuas ntxiv nthuav dav. Tshwj xeeb tshaj yog nyob rau hauv high-end teb xws li high-precision sib tsoo thiab polishing, daim ntawv thov ntawm corundum yog ua ntau thiab ntau dua.

Cov txheej txheem ntau lawm ntawm corundum

Cov txheej txheem ntau lawm ntawm corundum suav nrog ntau cov kauj ruam xws li kev npaj cov khoom, smelting, txias, crystallization thiab ua. Ua ntej, lub siab-purity aluminium oxide hmoov raug tshuaj xyuas thiab qhuav kom ntseeg tau tias qhov sib xws thiab purity ntawm cov ntaub ntawv raw. Tom qab ntawd, cov hmoov txhuas oxide yog muab tso rau hauv lub qhov cub hluav taws xob thiab muab tso rau hauv qhov kub thiab txias kom yaj nws mus rau hauv lub xeev ua kua. Nyob rau hauv lub xeev molten, cov txhuas oxide molecules rearrange lawv tus kheej los tsim ib tug siv lead ua qauv thiab tsim corundum hais. Tom qab ntawd, qhov kub thiab txias yog maj mam txo kom cov corundum hais maj mam solidify rau hauv cov khoom. Thaum kawg, nws yog rhuab dua los ua kom cov qauv siv lead ua ruaj khov thiab txhim kho hardness thiab hnav tsis kam ntawm corundum.

Taw qhia ntawm 200 mesh corundum high efficiency sib tsoo tshuab

Thaum corundum siv rau hauv qee qhov chaw, nws yuav tsum tau muab tso rau hauv 200-mesh hmoov zoo ua ntej, xws li hlau abrasives, iav ceramic cov ntaub ntawv, thiab cov khoom siv hluav taws xob semiconductor. Thawj kauj ruam yog feem ntau sib tsoo. Lub sijhawm no, koj yuav tsum siv 200-mesh corundum high-efficiency sib tsoo tshuab. Guilin Hongcheng yog ib qho khoom siv hauv tsev loj heev sib tsoo R & D thiab kev tsim khoom lag luam. HC series pendulum zeb nws tsim yog qhov kev xaiv zoo tshaj plaws rau 200-mesh corundum high-efficiency sib tsoo tshuab.

HC series viav vias mills muaj nyob rau hauv ntau hom qauv, nrog rau cov zis ib teev ntawm 1 tuj txog 50 tons. Cov cuab yeej ruaj khov thaum pib, qhov tsis zoo ntawm lub zog muaj kev sib khi zoo, qhov chaw ua haujlwm yog huv si thiab huv si, kev saib xyuas txhua hnub yog qhov yooj yim, thiab kev ua haujlwm thiab kev tu tus nqi qis. Nws yog dav siv hauv kev lag luam refractory thiab muaj kev ua haujlwm nplua nuj.

Guilin Hongcheng 200 mesh corundum high-efficiency sib tsoo tshuab yog maj mam dhau los ua cov cuab yeej tseem ceeb hauv kev ua cov pob zeb hauv av thiab cov khoom siv vim nws cov kev ua haujlwm siab, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Raws li cov khoom sib tsoo zoo, kev lag luam xav tau rau corundum txuas ntxiv zuj zus thiab kev cia siab rau kev lag luam yog dav. Zoo siab txais tos hu rau peb rau qhov tseeb hais.
