Ceramic Txhaj Molding Txias Sintering (CS)

Lub hauv paus txheej txheem ntawmceramic txhaj moldingCS thev naus laus zis yog ntxiv me me ntawm cov tshuaj aqueous rau cov hmoov ceramic kom ntub cov khoom, thiab cov khoom saum npoo ntawm cov hmoov yog decomposed thiab ib nrab yaj hauv cov tshuaj, yog li tsim cov kua theem ntawm particle-particle interface. Muab cov hmoov ntub dej tso rau hauv pwm, ua kom sov lub pwm, thiab siv lub zog loj rau tib lub sijhawm. Tom qab tuav lub siab thiab khaws cia rau ib lub sijhawm, cov khoom siv ceramic ntom ntom tuaj yeem npaj tau. Thaum lub sij hawm no, lub microstructure ntawm lubcov khoom siv ceramichloov zuj zus. raws li daim duab qhia.

Txawm hais tias muaj ntau yam cuam tshuam txog kev cuam tshuam ntawm CS txheej txheem, cov cuab yeej siv los ntawm cov thev naus laus zis no kuj yooj yim. , Cov khoom siv ceramic CS feem ntau suav nrog cov xovxwm zoo tib yam, ob lub phaj cua sov nruab rau sab saum toj thiab hauv qab ntawm cov xovxwm, thiab lub tsho hluav taws xob tswj cua sov kuj tseem tuaj yeem qhwv ib ncig ntawm cov pwm rau cua sov cov hmoov.

Oscillating Pressure Sintering rau Ceramic Txhaj MoldingCIM (OPS)

Ntau yam uas twb muaj lawm siab sintering technologies siv static siab tas li. Cov kev taw qhia ntawm static siab thaum lub sij hawmtxheej txheem sinteringpab tshem tawm cov pores thiab txhim kho qhov ntom ntawm ceramics, tab sis nws yog ib qho nyuaj rau ua tiav ionize thiab covalently daim ntawv cog lus tshwj xeeb ceramics. Kev cais tawm ntawm qhov pores hauv cov khoom tseem muaj qee yam kev txwv rau qhov xav tau kev npaj ntawm ultra-siab zog, siab toughness, siab hardness thiab siab ntseeg siab cov ntaub ntawv.
Cov laj thawj tseem ceeb ntawm cov kev txwv ntawm HP static siab sintering yog tshwm sim hauv 3 yam hauv qab no:

• ① Ua ntej pib sintering thiab nyob rau theem pib ntawm sintering, lub siab tas mus li tsis tuaj yeem paub txog qhov kev hloov pauv ntawm cov hmoov hauv pwm kom tau txais cov khoom ntim siab;
• ② Nyob rau hauv nruab nrab thiab tom qab theem ntawm sintering, cov yas ntws thiab tshem tawm cov agglomerates tseem txwv, thiab nws yog ib qho nyuaj rau ua tiav uniform densification ntawm cov khoom;
• ③ Nyob rau theem tom ntej ntawm sintering, nws yog ib qho nyuaj rau tshem tawm tag nrho cov pores seem nrog lub siab tas li.

Txog rau qhov kawg no, tus sau phau ntawv tshawb fawb pab pawg tau npaj ib lub tswv yim tsim tshiab ntawm kev qhia dynamic oscillating siab los hloov qhov uas twb muaj lawm static siab nyob rau hauv cov hmoov sintering txheej txheem, thiab coj tus thawj coj nyob rau hauv tsim ib tug OPS technology thiab khoom nyob rau hauv lub ntiaj teb no. Nyob rau hauv qhov kev txiav txim ntawm lub siab loj tas mus li, lub oscillating siab nrog adjustable zaus thiab amplitude yog superimposed tig lub "tuag quab yuam" siv nyob rau hauv ib txwm sintering rau "lub zog". Daim duab schematic ntawm oscillating siab coupling ntaus ntawv thiab lub hauv paus ntsiab lus yog qhia nyob rau hauv daim duab.

OPS thev naus laus zis tshiab muaj qhov zoo tshwj xeeb rau kev npaj cov ntaub ntawv nrog ze theoretical ntom ntom (ntau dua 99.9% ntawm theoretical ntom), qhov tsis xws luag, thiab ultra-fine grain microstructure. thiab kev ntseeg tau muab txoj hauv kev tshiab.
