Txoj Kev Sib Rau Rau Silicon Carbide Ceramics

Txoj kev ua rau Silicon Carbide Ceramics: ib qho kev qhia dav dav

Qhov tshwj xeeb siv lead ua qauv thiab cov khoom ntawm cov khoom ntawm Silicon Carbide Ceramics pab txhawb nws cov txiaj ntsig zoo. Lawv muaj lub zog zoo, muaj zog heev, hnav tsis kam tiv, corrosion tsis kam, siab thermal conduction. Cov khoom no ua cov silicon carbide ceramics zoo tagnrho rau cov ntawv thov ballistic.

Txoj kev sib haum ntawm silicon carbide ceramics feem ntau yog adopts cov hauv qab no:

1. COMPRESSION MOADING: COMPRESSION MOUNTING yog ib txoj kev siv dav rau kev tsim cov Silicon Carbide Bessage cov ntawv txheeb. Cov txheej txheem yooj yim, yooj yim ua lag luam, siab nyob rau hauv kev ua tau zoo thiab haum rau kev tsim khoom txuas ntxiv.

2. Txhaj tshuaj molding: txhaj tshuaj moulding muaj cov qauv yoog tau zoo thiab tuaj yeem tsim cov duab thiab cov qauv. Hom no yog qhov tshwj xeeb tshaj plaws thaum tsim cov khoom tshwj xeeb ntawm silicon carbide ceramic tej zaum.

3. Txias iostatic nias: Khaub thuas isostatic nias cuam tshuam nrog daim ntawv thov ntawm lub cev hnav rau lub cev ntsuab, ua rau muaj kev faib tawm ntom ntom ntom ntom. Cov thev naus laus zis tau txhim kho cov khoom lag luam thiab tsim nyog rau kev tsim cov kev ua haujlwm siab silicon carbide ceramics.

4. Gel txhaj tshuaj molding: GEL txhaj MOLDING yog tus tshiab nyob ze rau NET qhov loj me molding cov qauv. Lub cev ntsuab tsim muaj cov qauv kev coj ua thiab lub zog siab. Cov tau txais cov kab ceramic tuaj yeem ua tiav los ntawm ntau lub cav tov, uas txo tus nqi ua tom qab sintering. Gel txhaj tshuaj molding yog qhov tshwj xeeb rau kev tsim cov khoom silicon carbide ceramics nrog cov txheej txheem nyuaj.

Los ntawm kev siv cov qauv no, cov chaw tsim khoom tuaj yeem tau txais cov khoom lag luam zoo silicon carbide ceramics nrog cov khoom siv kho kom zoo nkauj thiab ballistic cov khoom. Muaj peev xwm los ua cov silicon carbide ceramics rau ntau yam ntawm cov duab thiab cov qauv tso cai rau kev kho kom haum thiab kev ua kom tau zoo kom tau raws li cov kev thov sib txawv ntawm cov ntawv thov sib txawv.

Tsis tas li ntawd, tus nqi-ua tau zoo ntawm Silicon Carbide Ceramics nce nws qhov kev txaus nyiam ua kev ua tau zoo ballistic-resistant cov ntaub ntawv. Qhov kev sib xyaw ntawm cov khoom tsim nyog thiab tus nqi tsim nyog ua rau Silicon Carbide Ceramics muaj qhov chaw muaj zog hauv lub cev thaj chaw.

Hauv kev xaus, silicon carbide ceramics yog cov ntaub ntawv ballistic vim lawv cov kev ua tau zoo thiab ntau yam moulding txoj kev. Cov qauv siv lead ua, lub zog, kev coj ua, thermal poob siab thiab thermal poob siab thiab thermal poob siab rau cov neeg tsim khoom thiab cov neeg tshawb xyuas. Nrog rau ntau hom kev sib tw ua ke, cov tuam ntxhab tuaj yeem ua kom cov khoom lag luam silicon carbide ceramics kom tau raws li cov ntawv thov thiab kev tiv thaiv zoo. Lub neej tom ntej ntawm Silicon Carbide Ceramics yog cov lus cog tseg thaum lawv txuas ntxiv txhim kho thiab ua tau zoo hauv cov ntaub ntawv ballistic.

Raws li deb li kev tiv thaiv kev tiv thaiv muaj kev txhawj xeeb, kev sib xyaw ntawm polyethylene nploojs thiab cov roj ceramic muaj pov thawj ua tau zoo heev. Ntawm cov kev xaiv ntau yam ceramic muaj, silicon carbide tau nyiam cov xim zoo nkauj ob leeg hauv tsev thiab txawv teb chaws. Nyob rau hauv xyoo tas los, cov neeg tshawb nrhiav thiab cov neeg tsim khoom tau tshawb nrhiav lub peev xwm ntawm cov zaub mov uas ntsiag to raws li nws cov khoom lag luam zoo thiab cov nqi ua tau zoo.

Silicon carbide yog lub compound tsim los ntawm stacking Si-c tetrahedrons, thiab muaj ob daim siv lead ua, α thiab β. Ntawm sinining kub hauv qab no 1600 ° C, Silicon Carbide muaj nyob rau hauv daim ntawv ntawm β-sic, thiab thaum qhov kub tshaj 1600 ° C, Silicon Carbide hloov mus rau hauv α-Sic. Lub Covalent Bond of α-silicon carbide muaj zog heev, thiab nws tuaj yeem ua kom muaj lub siab sib luag txawm tias muaj kub.
