Silicon Carbide Chaw tsim tshuaj paus
Tso lus
Los ntawm kev xav ntawm cov cuab yeej tsim khoom, cov xim dub silicon carbide feem ntau yog ua los ntawm quartz xuab zeb, roj av coke thiab silica ua cov khoom siv raw, thiab tom qab ntawd smelted nyob rau hauv lub qhov cub ua hauj lwm kub. Lub hardness ntawm dub silicon carbide yog siab heev, thiab lub hardness yog nruab nrab ntawm corundum thiab pob zeb diamond. Dub silicon carbide yog dav siv los ua abrasives thiab refractories vim nws cov hardness siab, zoo thermal conductivity thiab me me expansion coefficient.
Raws li cov chaw tsim khoom silicon carbide, txhawm rau tsim cov khoom zoo dub silicon carbide, ntxiv rau kev paub txog cov txheej txheem smelting kom raug, nws tseem yuav tsum nruj me ntsis tswj cov khoom zoo. Dub silicon carbide kuj muaj qee yam yuav tsum tau ua rau ntau yam khoom siv raw. Piv txwv li, silicon dioxide nyob rau hauv siliceous raw cov ntaub ntawv yuav tsum qis me ntsis, thiab cov ntsiab lus ntawm taag carbon nyob rau hauv roj av coke yuav tsum siab npaum li sai tau. Cov ntsiab lus tshauv yuav tsum tsawg dua 1.2 feem pua, thiab cov ntsiab lus tsis hloov pauv yuav tsum tsawg dua 12.0 feem pua . Qhov luaj li cas ntawm cov roj av coke yuav tsum tau tswj ntawm 2 hli thiab 1.5 hli. Thaum tsim cov dub silicon carbide, vim li cas vim li cas cov ntoo chips ntxiv yog tsuas yog los kho cov huab cua permeability ntawm lub cub tawg nqi nrog ntoo chips. Txawm li cas los xij, tus nqi ntawm sawdust kuj yuav tsum tau tswj hwm. Feem ntau, cov sawdust ntxiv yog li 3 feem pua - 5 feem pua.
Cov saum toj no yog los tswj qhov zoo ntawm raw cov ntaub ntawv thaum lub sij hawm zus tau tej cov dub silicon carbide. Tsuas yog los ntawm kev xyuam xim rau cov khoom siv raw tuaj yeem tsim cov khoom siv dub silicon carbide. Peb lub tuam txhab tau koom nrog hauv kev tsim khoom thiab muag khoom ntawm cov xim dub silicon carbide tau ntau xyoo, nrog kev paub nplua nuj thiab paub tab ntau lawm technology. Yog tias koj xav yuav dub silicon carbide, thov sab laj nrog peb lub tuam txhab.
