Microwave yekudziya choto inonyanya kuumbwa neyekutarisa system, control system, insulation bhokisi, microwave jenareta, bhokisi rekudziya uye gasi rekuchengetedza tangi.Bhokisi rekudziya rakagadzirwa nesimbi isina tsvina yegirazi ndiro.Mvura inotonhorera inogona kuyerera musandwich pakati pezvikamu zviviri zvesimbi isina tsvina kuti iwane kutonhora kwebhokisi rekudziya.
1. Nheyo ye microwave sintering yezvinhu zveceramic
Kuita kwezvinhu kune microwave kunogona kukamurwa kuva mamiriro mana: microwave reflection microwave transmission;kunwa microwave;kutorwa zvishoma kwemicrowave.Mazhinji masimbi anowira muchikamu chekutanga, nepo ese magirazi uye ceramic zvinhu zvinowira muzvikamu zvitatu zvekupedzisira.Kana mutumbi weceramic ukaiswa mumunda wemicrowave, simba rakanyura rinogona kuratidzwa neinotevera equation:
P = (2π fε ) ( E2/ 2) tan δ， Kana iyo microwave ichipinda muzvinhu, kusimba kwayo kunoderera nekudzika kwekupinda.Chinhambwe kubva pachinhu chepamusoro kusvika pakudzikisira kusvika 1/e yesimba remicrowave inotsanangurwa sekudzika kwekupinda Dp yemicrowave:
3λ 0
DP = π tan δ (ε r/ε 0) 1/ 2
8. 686
Ipi, P ndiyo microwave simba rinotorwa nemuviri weceramic;F ndiyo frequency;ε ndiyo inosanganiswa dielectric constant;λ 0 ndiyo yavelength yemicrowave muvacuum;E ndiko kusimba kwemunda wemagetsi;tan δ ndiyo kurasikirwa tangent ye dielectric ceramics;Iyo yekurasikirwa tangent (chiyero chekurasikirwa kweiyo dielectric constant) inowanzoshandiswa kuratidza kugona kwekubatanidza kwezvinhu kune microwave.Iyo yakakwirira yekurasikirwa tangent kukosha ndeye, kusimba kwekubatanidza kugona pakati pezvinhu uye microwave ndiko.
2. Dhizaini yewa microwave yakakwirira tembiricha yekudziya vira
Microwave yekudziya choto inonyanya kuumbwa neyekutarisa system, control system, insulation bhokisi, microwave jenareta, bhokisi rekudziya uye gasi rekuchengetedza tangi.Bhokisi rekudziya rakagadzirwa nesimbi isina tsvina yegirazi ndiro.Mvura inotonhorera inogona kuyerera musandwich pakati pezvikamu zviviri zvesimbi isina tsvina kuti iwane kutonhora kwebhokisi rekudziya.Iyo tembiricha sensor yatinoshandisa ndeye RAYR3I1MSCL2U infrared thermometer yeAmerican leitai kambani.Iyo control system inogona kuona manyorero ekutonga uye otomatiki kudzora.Kuti udzivise mugonhi revheni rewa microwave rakavharwa mushure mekunge microwave yekupisa choto kubva pamusuwo wevheni uye kubuda kunze kwepakati pakati pegomba, mukuwedzera pakudziya kwegonhi rechoto mukugadziridza uye kugadzira kuve nechokwadi chepamusoro dhimensional kurongeka uye kurongeka kwegungano, isu iyo microwave oven gonhi rakamisikidzwa rakatenderedza choke groove chimiro, chimiro ichi chinogona kunyatso kudzikisa kubuda kwe microwave.Sarudzo, dhizaini yemunda uye insulation ye microwave jenareta ndizvo zvinhu zvakakosha musintering chotodesign.
3. Microwave generator kusarudzwa
Mag netron, Klystron uye Gyrotron anowanzo kusarudzwa mune microwave kudziyisa michina.Se "moyo" we microwave sintering midziyo, sarudzo yayo ichakanganisa zvakananga kushanda uye mutengo wemidziyo yese.Iyo inowanzo shandiswa frequency mune microwave sintering mudziyo ndeiyi:
915 MHz, 2.45 GHz, 6 GHz, 28 GHz uye 60 GHz, zvichingodaro, magnetron inogona kusarudzwa se microwave jenareta kune yakaderera frequencies se 915 MHz uye 2.45 GHz, 6 GHz inogona kusarudzwa seyekumhanya inodzora chubhu, uye yakakwirira ma frequency. se28 GHz uye 60 GHz inogona kusarudzwa semagineti coil.
Sezvo kuwanda uye simba reakasiyana microwave jenareta zvichiwedzera, mutengo wavo wechiyero ($/ Watt) uchawedzera zvakanyanya.Kana simba guru re microwave jenareta richidiwa mukugadzira, zvinokurudzirwa kushandisa imwechete frequency uye yakaderera simba jenareta kuti uwane nesimba guru.
4.Design yekugadzirwa kwekudzivirira
Iyo inonyanya kushandiswa insulation chimiro mu microwave sintering vira inovigwa hupfu mhando uye bhokisi rudzi.Yakavigwa poda insulation chimiro ine zvakanakira yakanaka insulation maitiro.Nekudaro, kana sampuli dzakanyudzwa pane tembiricha yepamusoro, kunamatira pakati pemasampuli uye hupfu hwakavigwa zviri nyore kuitika.Mushure mekunge sampuli dzasiiwa, kusangana kwakananga kuchaitika.Asi chimiro ichi hachina kunaka sekuvigwa poda insulation chimiro.Kubatanidza hunhu hwemaviri ekudzivirira zvimiro, isu takagadzira bhokisi-mhando yekumisa chimiro.
