Microwave cua sov rauv yog tsim los ntawm kev saib xyuas, tswj qhov system, rwb thaiv tsev lub thawv, microwave generator, cua sov lub thawv thiab roj cia tank.Lub thawv cua sov yog ua los ntawm stainless hlau daim iav phaj.Cov dej txias tuaj yeem ntws hauv cov qhaub cij ntawm ob txheej ntawm stainless hlau phaj kom ua tiav cov cua txias ntawm lub thawv cua sov.
1. Lub hauv paus ntsiab lus ntawm microwave sintering ntawm cov ntaub ntawv ceramic
Cov tshuaj tiv thaiv ntawm cov khoom siv rau microwave tuaj yeem muab faib ua plaub qhov xwm txheej: microwave reflection microwave kis;microwave nqus;ib nrab nqus ntawm microwave.Cov hlau feem ntau poob rau hauv thawj qeb, thaum tag nrho cov iav thiab cov khoom siv ceramic poob rau hauv peb pawg tom kawg.Thaum lub cev ceramic muab tso rau hauv qhov chaw microwave, lub zog nqus tau tuaj yeem qhia los ntawm cov kab zauv hauv qab no:
P = (2π fε ) (E2 / 2) tan δ, Thaum lub microwave nkag mus rau cov khoom, nws qhov kev siv qis qis nrog qhov tob tob.Qhov kev ncua deb ntawm cov khoom nto mus rau qhov attenuation mus rau 1 / e ntawm microwave zog yog txhais raws li qhov tob tob Dp ntawm microwave:
3l0 ua
DP = π tan δ (ε r/ε 0) 1/2
8.686 ib
Qhov twg, P yog lub zog microwave nqus los ntawm lub cev ceramic;F yog qhov zaus;ε yog qhov sib xyaw dielectric tas li;λ 0 yog lub wavelength ntawm microwave hauv lub tshuab nqus tsev;E yog qhov siv zog ntawm hluav taws xob;tan δ yog qhov poob tangent ntawm dielectric ceramics;Qhov poob tangent (qhov piv ntawm qhov poob qhov tseem ceeb rau qhov dielectric tas li) feem ntau yog siv los qhia txog kev sib txuas ntawm cov khoom siv rau lub microwave.Qhov siab dua qhov poob tangent tus nqi yog, lub zog sib txuas ntawm cov khoom thiab microwave yog.
2. Tsim cov microwave kub kub cua sov rauv
Microwave cua sov rauv yog tsim los ntawm kev saib xyuas, tswj qhov system, rwb thaiv tsev lub thawv, microwave generator, cua sov lub thawv thiab roj cia tank.Lub thawv cua sov yog ua los ntawm stainless hlau daim iav phaj.Cov dej txias tuaj yeem ntws hauv cov qhaub cij ntawm ob txheej ntawm stainless hlau phaj kom ua tiav cov cua txias ntawm lub thawv cua sov.Qhov ntsuas kub peb siv yog RAYR3I1MSCL2U infrared tus pas ntsuas kub ntawm American leitai tuam txhab.Lub kaw lus tswj tau paub txog kev tswj hwm kev tswj hwm thiab kev tswj tsis siv neeg.Txhawm rau tiv thaiv hauv qhov cub microwave qhov rooj kaw tom qab microwave cua sov cua sov los ntawm lub qhov cub qhov cub thiab tawm ntawm qhov khoob ntawm cov kab noj hniav, ntxiv rau cov cua kub qhov rooj hauv kev ua thiab kev tsim khoom kom ntseeg tau qhov siab precision thiab sib dhos precision, peb nyob hauv lub qhov cub microwave qhov rooj nruab ib ncig ntawm lub choke groove qauv, cov qauv no tuaj yeem txo qhov to ntawm microwave.Kev xaiv, teb tsim thiab rwb thaiv tsev ntawm lub tshuab hluav taws xob microwave yog qhov tseem ceeb hauv qhovsintering rauvtsim.
3. Microwave generator xaiv
Mag netron, Klystron thiab Gyrotron feem ntau xaiv hauv cov khoom siv cua sov microwave.Raws li "lub plawv" ntawm cov khoom siv microwave sintering, nws cov kev xaiv yuav cuam tshuam ncaj qha rau kev ua haujlwm thiab tus nqi ntawm tag nrho cov khoom siv.Feem ntau siv nyob rau hauv microwave sintering ntaus ntawv yog:
915 MHz, 2.45 GHz, 6 GHz, 28 GHz thiab 60 GHz, thiab lwm yam. Feem ntau, magnetron tuaj yeem xaiv los ua lub tshuab hluav taws xob microwave rau qis zaus xws li 915 MHz thiab 2.45 GHz, 6 GHz tuaj yeem xaiv raws li kev tswj ceev ceev, thiab cov zaus ntau dua. xws li 28 GHz thiab 60 GHz tuaj yeem xaiv raws li cov hlau nplaum.
Raws li qhov zaus thiab lub zog ntawm ntau lub tshuab hluav taws xob microwave nce, lawv tus nqi piv ($ / Watt) yuav nce ntxiv.Yog tias xav tau lub tshuab hluav taws xob microwave siab hauv kev tsim, nws raug nquahu kom siv tib lub zaus thiab lub tshuab hluav taws xob qis kom tau txais los ntawm lub zog superposition.
4.Kev tsim qauv ntawm cov rwb thaiv tsev
Qhov feem ntau siv rwb thaiv tsev nyob rau hauv microwave sintering rauv yog faus hmoov hom thiab lub thawv hom.faus hmoov rwb thaiv tsev qauv muaj qhov zoo ntawm cov rwb thaiv tsev zoo.Txawm li cas los xij, thaum cov qauv sintered ntawm qhov kub siab dua, adhesion ntawm cov qauv thiab cov hmoov faus yog ib qho yooj yim tshwm sim.Tom qab cov qauv yog sintered, kev sib cuag ncaj qha yuav tshwm sim.Tab sis cov qauv no tsis zoo li faus hmoov rwb thaiv tsev qauv.Ua ke cov yam ntxwv ntawm ob lub rwb thaiv tsev, peb tsim ib lub thawv-hom rwb thaiv tsev qauv.
