Kev piav qhia
Silicon carbide (SiC) yog cov khoom siv hluavtaws ua los ntawm kev sib xyaw ntawm silicon thiab carbon. Nws muaj ntau yam kev siv hauv ntau yam lag luam xws li electronics, ceramics, thiab automotive. SiC paub txog nws qhov kev ua haujlwm kub kub, hardness, thiab hnav tsis kam, ua rau nws zoo heev rau cov cuab yeej txiav, cov khoom siv abrasive, thiab cov khoom siv hluav taws xob.
Kev tsim tawm ntawm SiC suav nrog cov txheej txheem nyuaj hu ua Acheson txheej txheem. Nyob rau hauv cov txheej txheem no, ib tug sib tov ntawm finely hmoov carbon thiab silicon yog rhuab mus rau qhov kub siab heev (nyob ib ncig ntawm 2, 000 degree ). Cov cua sov ua rau muaj kev cuam tshuam ntawm cov pa roj carbon thiab silicon, uas ua rau SiC nyob rau hauv daim ntawv ntawm crystals. Cov crystals ces crushed thiab sorted rau hauv ntau qhov ntau thiab tsawg rau kev siv sib txawv.
Cov txheej txheem Acheson tau tsim dua ib puas xyoo dhau los los ntawm Edward Acheson, uas tab tom nrhiav txoj hauv kev los tsim cov pob zeb diamond. Txawm hais tias nws tsis ua tiav nws lub hom phiaj, nws pom SiC, uas tau dhau los ua cov khoom lag luam muaj txiaj ntsig.

Lwm txoj hauv kev los ua SiC yog los ntawm cov tshuaj vapor deposition (CVD). Txoj kev no suav nrog cov cua sov, xws li silane lossis methyltrichlorosilane, nrog rau cov pa roj carbon monoxide, xws li propane, hauv lub reactor. Cov roj molecules reacts tsim SiC ntawm lub substrate nyob rau hauv lub reactor. CVD yog ib txoj kev ua tau zoo dua thiab meej piv rau cov txheej txheem Acheson, tab sis nws tseem tsis tau siv dav vim nws cov nqi siab thiab qhov nyuaj.
SiC muaj ntau qhov zoo dua lwm cov ntaub ntawv hauv ntau daim ntawv thov. Piv txwv li, nyob rau hauv electronics, SiC yog siv nyob rau hauv lub hwj chim electronics, qhov twg nws muaj peev xwm lis high voltage thiab kub yam tsis muaj degrading. SiC kuj tseem siv rau hauv daim ntawv thov tsheb, xws li nres nres thiab clutches, vim nws hnav tsis kam.
Hauv kev xaus, kev tsim cov SiC suav nrog cov txheej txheem nyuaj. Txawm li cas los xij, SiC cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo hauv ntau qhov kev lag luam. Nws tiv taus tshav kub, hardness, thiab hnav tsis kam ua rau nws zoo tagnrho rau cov cuab yeej txiav, cov ntaub ntawv abrasive, thiab cov khoom siv hluav taws xob. Nrog rau kev tshawb fawb thiab kev txhim kho ntxiv, SiC tuaj yeem dhau los ua ntau dua hauv ntau daim ntawv thov.
FAQ
Q: Koj them nyiaj li cas?
A: T / T, L / C, Nyiaj ntsuab tau txais.
Q: Kuv tuaj yeem tau txais qee qhov qauv thiab yuav siv sijhawm ntev npaum li cas?
A: Rau cov qauv me me, nws yog dawb, tab sis huab cua freight yog sau los yog them peb tus nqi ua ntej, peb feem ntau siv International Express, thiab peb yuav xa tuaj rau koj tom qab tau txais koj cov nqi.
Q: Koj puas tuaj yeem tsim raws li cov neeg siv khoom tsim?
A: Tseeb, peb yog cov chaw tsim khoom.
Q: Yuav ua li cas txog qhov zoo?
A: Los ntawm cov khoom siv raw 'xaiv, smelting, crushing, tiav cov khoom' kuaj, packing, mus kuaj ua ntej khoom xa tuaj, txhua kauj ruam, Zhenan neeg yog tag nrho cov siv nruj zoo tswj.
