Peb zoo siab tos txais cov neeg tuaj tshiab txawv teb chaws los teeb tsa kev lag luam kev sib cuam tshuam thiab tseem cia siab tias yuav koom ua ke kev sib cuam tshuam nrog txhua tus neeg siv khoom ntev.
Zoo zoo los pib nrog; kev pabcuam yog qhov tseem ceeb; lub koom haum yog kev koom tes "yog peb lub tswv yim kev lag luam uas tau ua raws li niaj hnub thiab ua raws li peb lub tuam txhabTuam Tshoj Molybdenum Crucible, Crucibles muag, Peb muab kev pabcuam kev paub, teb sai, xa khoom raws sijhawm, zoo heev thiab tus nqi zoo tshaj rau peb cov neeg siv khoom. Kev txaus siab thiab credit zoo rau txhua tus neeg siv khoom yog peb qhov tseem ceeb. Peb tsom mus rau txhua qhov kev nthuav dav ntawm kev txiav txim rau cov neeg siv khoom kom txog thaum lawv tau txais cov khoom muaj kev nyab xeeb thiab zoo nrog cov kev pabcuam logistics zoo thiab tus nqi pheej yig. Nyob ntawm qhov no, peb cov khoom muag tau muag zoo heev hauv cov tebchaws hauv Africa, Mid-East thiab Southeast Asia. Ua raws li kev lag luam lub tswv yim ntawm ?? cov neeg siv khoom ua ntej, forge ua ntej', peb zoo siab txais tos cov neeg siv khoom hauv tsev thiab txawv teb chaws los koom tes nrog peb.
Cov pa roj carbon / carbon composites(tom qab no hu ua "C / C lossis CFC") yog ib hom khoom sib xyaw uas yog raws li cov pa roj 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 siab zog ntawm carbon fiber. Nws muaj cov khoom siv zoo, ua haujlwm kub, tiv thaiv corrosion, kev sib txhuam damping thiab thermal thiab hluav taws xob conductivity yam ntxwv
CVD-SiCtxheej txheej muaj cov yam ntxwv ntawm cov qauv zoo, cov khoom siv compact, kub tsis kam, oxidation tsis kam, siab purity, acid & alkali tsis kam thiab organic reagent, nrog lub cev ruaj khov thiab tshuaj lom neeg.
Piv nrog cov khoom siv graphite siab, graphite pib oxidize ntawm 400C, uas yuav ua rau poob ntawm cov hmoov vim oxidation, ua rau ib puag ncig muaj kuab paug rau peripheral li thiab lub tshuab nqus tsev chamber, thiab ua rau impurities ntawm high-purity ib puag ncig.
Txawm li cas los xij, SiC txheej tuaj yeem tswj 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 SiC txheej txheej txheem kev pab cuam los ntawm CVD txoj kev nyob rau saum npoo ntawm graphite, ceramics thiab lwm yam ntaub ntawv, kom tshwj xeeb gases uas muaj carbon thiab silicon react ntawm kub kom tau siab purity SiC molecules, molecules tso rau saum npoo ntawm cov ntaub ntawv coated, tsim SIC tiv thaiv txheej. SIC tsim yog ruaj khov rau graphite puag, muab cov graphite puag tshwj xeeb, yog li ua rau saum npoo ntawm graphite compact, Porosity-dawb, kub tsis kam, corrosion kuj thiab oxidation kuj.
Cov yam ntxwv tseem ceeb:
1. Kub oxidation kuj:
oxidation kuj tseem zoo heev thaum kub siab li 1600 C.
2. High purity: ua los ntawm cov tshuaj vapor deposition nyob rau hauv siab kub chlorination mob.
3. Erosion kuj: siab hardness, compact nto, zoo hais.
4. Corrosion kuj: acid, alkali, ntsev thiab organic reagents.
