Peb paub tias peb tsuas muaj kev vam meej yog tias peb tuaj yeem lav peb cov nqi sib tw ua ke thiab cov txiaj ntsig zoo tib lub sijhawm rau Cov Neeg Siv Khoom Sab saum toj Grey Black Silicon Carbide Sic Carborundum Tuam Tshoj Siab Purity, Peb txais tos cov neeg siv khoom tshiab thiab yav dhau los los ntawm txhua qhov chaw ntawm lub neej los hais lus rau peb rau foreseeable yav tom ntej lub koom haum kev sib raug zoo thiab tau txais kev sib nrig sib achievements!
Peb paub tias peb tsuas vam meej yog tias peb tuaj yeem lav peb cov nqi sib tw ua ke thiab kev ua tau zoo zoo tib lub sijhawm rauTuam Tshoj Txheej Khoom, Titanium Dioxide, Peb lub tuam txhab txhawb nqa tus ntsuj plig ntawm "kev tsim kho tshiab, kev sib haum xeeb, kev ua haujlwm pab pawg thiab kev sib koom ua ke, txoj hauv kev, kev ua tiav zoo". Muab sijhawm rau peb thiab peb yuav ua pov thawj peb lub peev xwm. Nrog koj kev pab zoo, peb ntseeg tias peb tuaj yeem tsim lub neej yav tom ntej nrog koj ua ke.
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.
