1. Tus cawv ntawm raw cov khoom siv
Cov ntaub ntawv ntau lawm koom nrog kev sib xyaw ua keSilicon Nitride Thiab Silicon Carbide CibXws li cov tshuaj ntxiv xws li Silicon Carbide, Silicon Hmoov, thiab Nitrogen Gas. Tsis zoo li cov khoom silicon ib yam, cov ntaub ntawv raw rau silicon nitride ua ke nrog silicon carbide cov khoom yuav tsum muaj kev coj dawb huv. Lub purity ntawm silicon carbide yuav tsum yog saum toj 98.5%, cov hmoov uas muaj kev coj dawb huv yuav tsum yog saum 99%, thiab lub nitrogen yuav tsum nyob saum 99.9%. Ntxiv nrog rau kev tswj nruj dhau ntawm cov ntaub ntawv raw, nruj me ntsis cov ntaub ntawv thiab muab qhab nia ntawm cov txheej txheem raw yog tseem yuav tsum tau ua rau kev tsim khoom thiab kev ua tiav. Ntau qhov me me ntawm cov khoom siv raw yuav cuam tshuam ncaj qha rau cov leeg ntom ntom ntawm cov embryo, ua rau muaj kev txo qis ntawm cov embryo thiab cuam tshuam qhov zoo ntawm cov khoom kawg. Nyob rau hauv cov nqe lus ntawm particle loj muab faib cov ntaub ntawv raw, saib yuav tsum tau them rau qhov me me ntawm cov hmoov sillicon. Particle Qhov loj me tswj ntawm silicon hmoov tuaj yeem ua kom cov tshuaj tiv thaiv kev ua haujlwm ntawm silicon hmoov thiab nitrogen roj. Txawm li cas los xij, dig muag txo qhov me me ntawm cov dej uas muaj zog thiab cov tshuaj tiv thaiv nitrogen yuav ua rau cov khoom siv kub ua kom sov thiab nce ntxiv hauv cov tshuaj tiv thaiv. Thaum qhov ntsuas kub tshaj 1400 degree, nws yuav ntxias silicon ntws ntawm qhov chaw ntawm silicon carbide, uas tsis muaj txiaj ntsig rau cov khoom lag luam zoo. Ib qho ntxiv, ntxiv ZRSIO4 rau cov ntaub ntawv raw ntawm silicon nitride ua ke nrog silicon carbide cov khoom tuaj yeem txhim kho cov oxidation tsis kam ntawm cov khoom.
2. Tus cawv ntawm binders
Hauv cov txheej txheem ntau lawm ntawmSilicon nitride ua ke nrog silicon carbide cib, yuav tsum tau muab ib ntus. Qhov sib ntxiv ntawm cov kev sib txuas no muaj ob qhov tseem ceeb: ua ntej, nws tuaj yeem pab cov khoom siv ntawm cov khoom siv raw ua kom tiav, thiab tsim cov kev ua kom haum xeeb rau embryo tsim; Thib ob,Silicon Nitride Bonded Silicon Carbide KhoomNtsej muag muaj txheej txheem cua sov thaum ziab thiab tua hluav taws txheej txheem. Nyob rau hauv cov kev mob siab, lub sijhawm ib ntus nyob rau hauv Silicon Nitride cov khoom sib tsoo yuav decomle Qhov no tsis tsuas yog ua kom cov pa roj tso tawm ntawm cov tshuaj tiv thaiv kev ua haujlwm thiab cov pa roj ntsha, tab sis kuj ua rau muaj kev ruaj ntseg ntawm cov khoom kawg. Ib ntus binders tsuas yog muaj xws li organic dextrins, calcium lignosulfonate, thiab German D Sima Tshuaj Dispersants. Tam sim no, feem pua feem pua ntawm cov kev sib txuas lus ib ntus ntxiv hauv kev lag luam feem ntau tsis pub dhau 5%.
3. Qhov cuam tshuam ntawm cov txheej txheem molding
Tam sim no, cov txheej txheem moulding ntawmSilicon nitride ua ke nrog silicon carbide cibMas suav nrog ob pawg: semi qhuav moulding thiab grouting moulding. Ntawm lawv, ib nrab txheej qhuav yog feem ntau siv vim nws qhov siab ntau lawm tau txais txiaj ntsig. Cov txheej txheem tseem ceeb uas siv hauv kev ua haujlwm yog kev txhaj tshuaj molding, uas yuav tsum muaj kev ua tau zoo ntawm slurry. Muaj ntau ntau yam uas txiav txim siab qhov zoo ntawm kev kho hniav, ntawm kev kho mob saum npoo ntawm silicon carbide micro hmoov ua lub luag haujlwm tseem ceeb heev.
