Tau txais cov neeg yuav khoom ua tiav yog peb lub tuam txhab lub hom phiaj tsis muaj qhov kawg. Peb yuav ua cov tswv yim zoo heev kom tau txais cov kev daws teeb meem tshiab thiab zoo tshaj plaws, ua tau raws li koj qhov tshwj xeeb tshwj xeeb thiab muab rau koj nrog kev muag khoom ua ntej, ntawm-muag thiab tom qab-muag cov neeg muab kev pabcuam rau Cov Khoom Kub Tshiab Plasma Enhanced CVD Tube Rau Deposition ntawm High- Quality Hard Films, Zoo siab txais tos koj cov lus nug, cov kev pabcuam zoo tshaj plaws yuav muab rau tag nrho lub siab.
Tau txais cov neeg yuav khoom ua tiav yog peb lub tuam txhab lub hom phiaj tsis muaj qhov kawg. Peb yuav ua cov tswv yim zoo heev kom tau txais cov kev daws teeb meem tshiab thiab zoo tshaj plaws, ntsib nrog koj qhov tshwj xeeb tshwj xeeb thiab muab rau koj nrog kev muag khoom ua ntej, ntawm-muag thiab tom qab-muag cov neeg muab kev pabcuam rauTuam Tshoj CVD Tube Rauv thiab CVD Tube Rauv Chemical Vapor Deposition, Nyob rau hauv kev sib tw ua lag luam, Nrog rau kev pabcuam siab zoo cov khoom zoo thiab tsim nyog lub koob npe nrov, peb ib txwm muab cov neeg siv khoom txhawb nqa ntawm cov khoom thiab cov txheej txheem kom ua tiav kev koom tes ntev. Ua neej nyob zoo, kev loj hlob los ntawm credit yog peb txoj kev nrhiav mus ib txhis, Peb ntseeg siab tias tom qab koj tuaj xyuas peb yuav dhau los ua cov neeg koom tes ntev.
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.
