Siv tag nrho cov txheej txheem kev tswj xyuas zoo, zoo tshaj plaws thiab kev ntseeg zoo, peb tau txais lub npe zoo thiab nyob hauv daim teb no rau Tuam Tshoj lag luam wholesale Tuam Tshoj Chaw tsim tshuaj paus ntawm High Quality Graphite Crucible / Nkoj, peb tuaj yeem daws peb cov neeg siv khoom teeb meem sai li sai tau thiab ua cov txiaj ntsig rau peb. cov neeg siv khoom. Rau cov neeg xav tau kev pab zoo tshaj thiab zoo heev, pls xaiv peb, ua tsaug!
Siv tag nrho cov txheej txheem kev tswj hwm kev tshawb fawb zoo, zoo tshaj plaws thiab kev ntseeg zoo, peb tau txais lub npe zoo thiab nyob hauv daim teb no rauTuam Tshoj Crucible, Graphite Crucible, peb muaj cov khoom ua tiav cov kab ntau lawm, cov kab sib dhos, kev tswj xyuas qhov zoo, thiab qhov tseem ceeb tshaj plaws, peb muaj ntau lub tshuab patents thiab kev paub txog kev tsim khoom, pab pawg muag khoom tshwj xeeb. Nrog rau tag nrho cov neeg zoo, peb tau npaj siab los tsim "lub koob npe nrov thoob ntiaj teb hom nylon monofilaments", thiab nthuav peb cov khoom mus rau txhua lub ces kaum ntawm lub ntiaj teb. Peb tau txav mus los thiab sim peb qhov zoo tshaj plaws los pab peb cov neeg siv khoom.
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.
