Peb lub tuam txhab hais txog txoj cai zoo ntawm "khoom zoo yog lub hauv paus ntawm kev ciaj sia ntawm lub tuam txhab; kev txaus siab ntawm tus neeg yuav khoom yuav yog qhov pib thiab qhov kawg ntawm lub tuam txhab; kev txhim kho tas mus li yog kev nrhiav neeg ua haujlwm tas mus li "ntxiv rau lub hom phiaj tas mus li ntawm "lub koob npe nrov ua ntej, tus neeg yuav khoom ua ntej" rau Lub Hoobkas Ncaj Qha muab Tuam Tshoj Electro Graphite Block, Cov neeg ua haujlwm ntawm peb lub tuam txhab nrog txhua yam kev siv cov thev naus laus zis tshiab muab cov kev daws teeb meem zoo tshaj plaws uas peb cov neeg siv khoom thoob ntiaj teb nyiam thiab txaus siab.
Peb lub tuam txhab hais txog txoj cai zoo ntawm "qhov zoo ntawm cov khoom yog lub hauv paus ntawm kev ciaj sia ntawm lub tuam txhab; kev txaus siab ntawm tus neeg yuav khoom yuav yog qhov pib thiab qhov kawg ntawm lub tuam txhab; kev txhim kho tas mus li yog kev nrhiav neeg ua haujlwm tas mus li" thiab lub hom phiaj tas mus li ntawm "lub koob npe nrov ua ntej, tus neeg yuav khoom ua ntej" rauCov Pa roj carbon Block, Tuam Tshoj Graphite Block, Peb cov neeg ua haujlwm ua raws li "Kev Ncaj Ncees thiab Kev Sib Tham Sib Tham", thiab lub hauv paus ntawm "Zoo Tshaj Plaws nrog Kev Pabcuam Zoo". Raws li qhov xav tau ntawm txhua tus neeg siv khoom, peb muab cov kev pabcuam tshwj xeeb & tus kheej los pab cov neeg siv khoom ua tiav lawv lub hom phiaj kom ua tiav. Txais tos cov neeg siv khoom los ntawm tsev thiab txawv teb chaws los hu thiab nug!
Cov khoom sib xyaw ua los ntawm cov pa roj carbon / carbon(txij no mus hu ua "C / C lossis CFC”) yog ib hom khoom sib xyaw ua ke uas yog ua los ntawm carbon thiab txhawb nqa los ntawm carbon fiber thiab nws cov khoom (carbon fiber preform). Nws muaj ob qho tib si inertia ntawm carbon thiab lub zog siab ntawm carbon fiber. Nws muaj cov khoom siv kho tshuab zoo, tiv taus cua sov, tiv taus corrosion, txhuam damping thiab thermal thiab hluav taws xob conductivity yam ntxwv.
CVD-SiCtxheej muaj cov yam ntxwv ntawm cov qauv sib xws, cov khoom siv compact, kub tsis kam, oxidation tsis kam, siab purity, acid & alkali tsis kam thiab organic reagent, nrog cov khoom ruaj khov thiab tshuaj lom neeg.
Piv nrog cov ntaub ntawv graphite uas muaj cov khoom purity siab, graphite pib oxidize ntawm 400C, uas yuav ua rau poob cov hmoov vim yog oxidation, ua rau muaj kuab paug rau ib puag ncig rau cov khoom siv peripheral thiab cov chaw nqus tsev, thiab ua rau cov khoom tsis huv ntawm ib puag ncig uas muaj cov khoom purity siab nce ntxiv.
Txawm li cas los xij, SiC txheej tuaj yeem tswj tau lub cev thiab tshuaj lom neeg ruaj khov ntawm 1600 degrees, Nws yog dav siv hauv kev lag luam niaj hnub, tshwj xeeb tshaj yog hauv kev lag luam semiconductor.
Peb lub tuam txhab muab cov kev pabcuam txheej txheem SiC los ntawm CVD txoj kev rau ntawm qhov chaw ntawm graphite, ceramics thiab lwm yam khoom siv, yog li cov pa roj tshwj xeeb uas muaj cov pa roj carbon thiab silicon teb rau qhov kub siab kom tau txais cov khoom siv SiC ntshiab siab, cov khoom siv tso rau ntawm qhov chaw ntawm cov khoom siv coated, tsim cov txheej tiv thaiv SIC. Cov SIC tsim tau sib txuas ruaj khov rau lub hauv paus graphite, muab cov khoom tshwj xeeb rau lub hauv paus graphite, yog li ua rau qhov chaw ntawm graphite compact, tsis muaj porosity, tiv taus kub siab, tiv taus corrosion thiab tiv taus oxidation.
Cov yam ntxwv tseem ceeb:
1. Kev tiv thaiv oxidation kub siab:
qhov kev tiv thaiv oxidation tseem zoo heev thaum qhov kub siab txog 1600 C.
2. Kev huv siab: ua los ntawm cov tshuaj lom neeg ua pa hauv qab qhov kub siab chlorination.
3. Kev tiv thaiv kev yaig: kev nyuaj siab, qhov chaw me me, cov khoom me me.
4. Kev tiv thaiv corrosion: acid, alkali, ntsev thiab cov organic reagents.
