Khoom Description

Silicon carbide (SiC), tseem hu ua carborundum, yog ib hom tshuaj nyuaj uas muaj silicon thiab carbon, yog ib hom tshiab ntawm cov khoom muaj zog deoxidizer, uas hloov cov tsoos silicon carbon hmoov rau deoxidation, piv nrog cov txheej txheem qub, lub cev thiab tshuaj lom neeg muaj zog dua, thiab cov nyhuv deoxidation yog qhov zoo. SiC feem ntau yog tsim nyob rau hauv lub qhov cub tsis kam ntawm qhov kub ntawm 1700 - 2500 degree. Silicon carbide tau ua cov khoom tseem ceeb hauv cov ntawv xuab zeb, sib tsoo lub log, thiab cov cuab yeej txiav txij thaum xyoo pua 19th. Nyob rau hauv xyoo tas los no, nws tau pom cov ntawv thov nyob rau hauv cov ntaub ntawv refractory thiab cov khoom cua sov rau cov khoom siv hluav taws xob, hnav-cov khoom tiv thaiv rau cov twj tso kua mis thiab foob pob hluav taws, thiab cov khoom siv hluav taws xob rau lub teeb -emitting diodes.

SiC yog cov khoom tsim los ntawm cov tshuaj tiv thaiv ntawm cov khoom siv carbon tov nrog silicon dioxide lossis quartz xuab zeb, uas tsim los ua ib qho khoom cylindrical ingot nyob ib ncig ntawm lub hauv paus, nrog cov txheej radial xws li graphite rau sab hauv mus rau -SiC (qhov siab tshaj - cov khoom qib nrog ntxhib crystalline qauv), - thiab grade metallurgy. un-reacted cov khoom nyob rau sab nraud, uas yog remelted. SiC tuaj yeem ua rau dub lossis ntsuab, nyob ntawm cov khoom siv raw.

Dub silicon carbide (SiC) muaj ntau dua 95%, thiab nws cov tawv tawv yog siab dua li ntawm ntsuab silicon carbide. Nws feem ntau yog siv rau kev ua cov ntaub ntawv uas tsis muaj zog tensile, xws li iav, ceramics, pob zeb, refractory cov ntaub ntawv, cam khwb cia hlau, thiab tsis yog -ferrous hlau.

Ntsuab silicon carbide muaj ntau dua 97% SiC, yog xim ntsuab, muaj zog hardness thiab brittleness dua TH, thiab muaj thermal conductivity thiab hluav taws xob conductivity. riam hlau.

Tsis tas li ntawd, muaj cubic silicon carbide, uas yog daj -ntsuab siv lead ua uas tsim los ntawm cov txheej txheem tshwj xeeb. Cov cuab yeej abrasive siv los ua nws yog tsim rau superfinishing ntawm bearings. Qhov saum npoo roughness tuaj yeem ua tiav los ntawm Ra32-0.16 microns rau Ra0.04- 0.02 microns.

Tom qab txias, SiC ingots raug txheeb xyuas kom raug, feem ntau manually los ntawm cov neeg ua haujlwm txawj, thiab ua tiav ntxiv rau cov ntawv thov sib txawv. Cov khoom siv SiC yog tom qab ntawd ua tib zoo crushed, thiab txheeb, yog tias tsim nyog, hauv av dua. Lwm qhov kev xaiv yog txhawm rau kho tshuaj ntxiv SiC kom tau txais cov khoom tshwj xeeb rau nws daim ntawv thov.

Peb muag SiC hauv cov duab ntawm cov blocks, granules, thiab hmoov.

Ntim: Xa hauv dej-cov ntaub ntawv pov thawj lub hnab yas, 1000kg ib lub hnab lossis raws li koj xav tau.

Loj: 0-5mm, 0-10mm, 10-50mm, kuj tuaj yeem muab kev cai.
