Ceramic sintering txheej txheem
Sintering yog ib qho cuab yeej siv hluav taws xob siv hluav taws xob los ua kom cov hmoov nplej. Lub ntsiab lus ntawm sintering yog hais txog cov txheej txheem densification ntawm porous ceramic billet nyob rau hauv qhov kub thiab txias, qhov chaw saum npoo yog txo, qhov porosity yog txo, thiab cov khoom siv kho kom zoo tuaj. Tsuas yog los ntawm kev paub txog txoj cai ntawm kev hloov pauv ntawm lub cev hauv cov txheej txheem ntawm kev kub hnyiab, raug xaiv thiab tsim lub kiln, scientifically formulating thiab siv lub firing system, thiab nruj me ntsis siv cov txheej txheem kev khiav hauj lwm ntawm loading thiab firing, cov khoom zoo tuaj yeem txhim kho, kev siv roj tsawg, thiab cov txiaj ntsig zoo nyiaj txiag tau txais.

Cov txheej txheem thev naus laus zis cuam tshuam rau sintering ntawm cov ntaub ntawv ceramic
(1) Qhov cuam tshuam ntawm qhov kub thiab txias ntawm cov khoom ua haujlwm
- Qhov hluav taws kub kub yog hais txog qhov kub thiab txias thaum lub cev ceramic raug rho tawm haujlwm kom tau txais cov cuab yeej zoo, uas yog, hluav taws kub ceev thaum ua haujlwm.
- Qhov ntsuas kub ntawm qhov hluav taws kub ncaj qha cuam tshuam qhov loj thiab tus naj npawb ntawm cov nplej. Rau cov theem khoom diffusion los yog kua theem recrystallization, nws yog qhov zoo los ua kom qhov kub thiab txias. Txawm li cas los xij, rau cov plooj (porcelain) tshwj xeeb, kub kub kub dhau heev yuav ua rau tag nrho cov qoob loo loj dhau los yog cov qoob loo me me kom nce siab, ua kom tsis zoo ntawm lub koom haum cov qauv, yog li deteriorating lub electromechanical zog ntawm cov khoom.
(2) Qhov cuam tshuam ntawm kev tuav lub sijhawm ntawm cov khoom ua haujlwm
Kev tswj xyuas qhov kub siab tshaj plaws rau ib lub sijhawm ntawm lub sijhawm yuav, ntawm ib sab, ua rau lub cev thiab tshuaj hloov pauv ntau dua, kom lub cev ntsuab yuav muaj cov kua dej txaus thiab cov qoob loo uas tsim nyog, thiab ntawm qhov tod tes, lub koom haum cov qauv kuj yuav ua kom zoo dua qub. Txawm li cas los xij, yog tias lub sijhawm khaws cia kub ntev dhau lawm, cov khoom siv lead ua yuav yaj, uas tsis yog qhov tsim nyog rau kev tsim cov pob txha muaj zog hauv qhov khoob thiab txo cov khoom siv dag zog.
(3) Qhov cuam tshuam ntawm kev tua hluav taws ntawm cov khoom ua haujlwm
- Kev cuam tshuam ntawm huab cua nyob rau hauv qhov tshaj-firing expansion ntawm ceramic lub cev
- Cov nyhuv ntawm huab cua ntawm lub shrinkage thiab sintering ntawm lub cev ntsuab
- Kev cuam tshuam ntawm huab cua ntawm cov xim thiab kev xa tawm ntawm qhov khoob thiab qhov zoo ntawm glaze txheej.
(4) Kev cuam tshuam ntawm cua sov thiab cua txias ceev ntawm cov khoom ua haujlwm
Solid-theem sintering feem ntau tuaj yeem muab faib ua peb theem: thawj theem, uas feem ntau tshwm sim los ntawm kev hloov pauv ntawm cov duab; theem nrab, uas yog feem ntau tshwm sim los ntawm kev hloov ntawm pore zoo; theem kawg, uas yog feem ntau tshwm sim los ntawm kev txo qhov pore loj.
Kua theem sintering (LPS luv luv) yog hais txog sintering ntawm lub cev uas muaj ntau yam hmoov. Qhov kub ntawm sintering tsawg kawg yog siab tshaj qhov kub melting ntawm ib qho ntawm cov hmoov, kom cov kua theem sintering tshwm sim thaum lub sij hawm sintering txheej txheem. txheej txheem.
qhov zoo:
- Txhim kho sintering tsav quab yuam.
- Ceramic composite cov ntaub ntawv nrog tswj microstructure thiab optimized zog tuaj yeem npaj tau

Featured sintering-kub xovxwm sintering
Kub nias siv lub siab rau qhov dawb paug tib lub sijhawm thaum lub sijhawm sintering, uas ua rau cov txheej txheem densification. Yog li ntawd, qhov kub ntawm kub xovxwm sintering yog qis dua thiab lub sij hawm sintering yog luv dua.
Kub nias tshuab muaj keeb kwm ntawm 70 xyoo thiab yog thawj zaug siv nyob rau hauv kev npaj ntawm tungsten carbide thiab tungsten hmoov ntom qhov chaw. Nws yog tam sim no dav siv nyob rau hauv lubkev tsim cov ceramics,hmoov metallurgythiab cov ntaub ntawv sib xyaw.
Qhov zoo ntawm kub xovxwm sintering
- Qhov xav tau molding siab tsuas yog 1/10 ntawm cov txheej txheem txias txias
- Txo qhov kub ntawm sintering thiab shortening lub sij hawm sintering inhibits kev loj hlob ntawm nplej.
- Nws yog ib qho yooj yim kom tau txais cov khoom uas muaj cov khoom zoo thiab cov khoom siv hluav taws xob.
- Muaj peev xwm tsim cov khoom nrog cov duab nyuaj thiab meej qhov ntev.
