Iziko lokufudumeza iMicrowave ikakhulu liqulunqwe yinkqubo yokubeka iliso, inkqubo yokulawula, ibhokisi yokugquma, ijenereyitha yemicrowave, ibhokisi yokufudumeza kunye netanki yokugcina igesi.Ibhokisi yokufudumeza yenziwe ngepleyiti yesipili yensimbi engenasici.Amanzi okupholisa anokuhamba kwisangweji phakathi kweeleya ezimbini zepleyiti yentsimbi engatyiwayo ukuze kuphunyezwe ukupholisa kwebhokisi yokufudumeza.
1. Umgaqo-siseko we-microwave sintering yezinto ze-ceramic
Ukusabela kwemathiriyeli kwi-microwave kunokohlulwa ngokweemeko ezine: microwave reflection microwave transmission;ukufakwa kwi-microwave;ukufunxa ngokuyinxenye kwi-microwave.Uninzi lwesinyithi luwela kudidi lokuqala, ngelixa zonke iglasi kunye nezixhobo ze-ceramic ziwela kwiindidi ezintathu zokugqibela.Xa umzimba we-ceramic ubekwe kwibala le-microwave, amandla afunliweyo angabonakaliswa ngolu hlobo lulandelayo:
P = (2π fε ) ( E2/ 2) tan δ，Xa i-microwave ingena kwizinto eziphathekayo, ubunzulu bayo buyancipha ngobunzulu bokungena.Umgama ukusuka kumphezulu wemathiriyeli ukuya kuncitshiswa ukuya kwi-1/e yamandla e-microwave uchazwa njengobunzulu bokungena kwi-Dp ye-microwave:
3 λ0
DP = π tan δ (ε r/ε 0) 1/ 2
8. 686
Apho, i-P inamandla e-microwave afunxwa ngumzimba we-ceramic;F yi-frequency;ε yidielectric edityanisiweyo engaguqukiyo;λ 0 bubude be-microwave kwi-vacuum;E bubunzulu bebala lombane;itan δ yilahleko yeeseramikhi zedielectric;I-tangent yelahleko (umlinganiselo welahleko kwi-dielectric constant) idla ngokusetyenziselwa ukubonisa amandla okudibanisa izinto kwi-microwave.
2. Uyilo lwe-microwave yobushushu obuphezulu beziko lokufudumeza
Iziko lokufudumeza iMicrowave ikakhulu liqulunqwe yinkqubo yokubeka iliso, inkqubo yokulawula, ibhokisi yokugquma, ijenereyitha yemicrowave, ibhokisi yokufudumeza kunye netanki yokugcina igesi.Ibhokisi yokufudumeza yenziwe ngepleyiti yesipili yensimbi engenasici.Amanzi okupholisa anokuhamba kwisangweji phakathi kweeleya ezimbini zepleyiti yentsimbi engatyiwayo ukuze kuphunyezwe ukupholisa kwebhokisi yokufudumeza.Isivamvo sobushushu esisisebenzisayo yi-RAYR3I1MSCL2U thermometer ye-infrared yenkampani ye-leitai yaseMelika.Inkqubo yokulawula inokuqonda ulawulo lwezandla kunye nolawulo oluzenzekelayo.Ukuze uthintele kumnyango we-oven microwave uvalwe emva kokuba i-oven microwave ifudumeze iziko ukusuka kumnyango we-oven kunye nokuvuza ngaphandle kwezithuba phakathi komngxuma, ukongeza kucango lokufudumeza ekuqhubeni nasekuveliseni ukuqinisekisa ukuchaneka okuphezulu kunye nokuchaneka kwendibano, thina Ucango lwe-oven microwave efakwe malunga nesakhiwo se-oven groove, esi sakhiwo sinokunciphisa ngokufanelekileyo ukuvuza kwe-microwave.Ukhetho, uyilo lwentsimi kunye nokufakelwa kwejenereyitha ye-microwave yimiba ephambili kwiiziko lokutshisauyilo.
3. Ukukhetha ijeneretha yeMicrowave
IMag netron, iKlystron kunye neGyrotron zikhethwa ngokubanzi kwizixhobo zokufudumeza ii-microwave.Njengoko "intliziyo" yezixhobo ze-microwave sintering, ukhetho lwayo luya kuchaphazela ngokuthe ngqo ukusebenza kunye neendleko zezixhobo zonke.Amaxesha aqhelekileyo asetyenziswa kwisixhobo sokutshiza se-microwave yile:
915 MHz, 2.45 GHz, 6 GHz, 28 GHz kunye 60 GHz, njl. Ngokuqhelekileyo, imagnetron ingakhethwa njengejenereyitha ye-microwave kumaza asezantsi afana ne-915 MHz kunye ne-2.45 GHz, i-6 GHz inokukhethwa njengetyhubhu yokulawula isantya, kunye nokuphakama okuphezulu njenge-28 GHz kunye ne-60 GHz inokukhethwa njenge-coil magnetic.
Njengoko i-frequency kunye namandla eejeneretha ezahlukeneyo ze-microwave zinyuka, umlinganiselo wabo wexabiso ($ / Watt) uya kunyuka kakhulu.Ukuba ijenereyitha ye-microwave yamandla aphezulu iyafuneka kuyilo, kuyacetyiswa ukuba kusetyenziswe i-frequency efanayo kunye nejenereyitha yamandla aphantsi ukufumana ngamandla aphezulu.
4.Uyilo lwesakhiwo se-insulation
Esona sakhiwo sisetyenziswa ngokuqhelekileyo kwisithando somlilo se-microwave singcwatywa uhlobo lomgubo kunye nohlobo lwebhokisi.Isakhiwo sokugquma umgubo ongcwatywayo sineenzuzo zesiphumo esihle sokugquma.Nangona kunjalo, xa iisampuli zifakwe kwiqondo lokushisa eliphezulu, ukunamathela phakathi kweesampuli kunye nomgubo ongcwatywe kulula ukwenzeka.Emva kokuba iisampuli zifakwe, uqhagamshelwano oluthe ngqo luya kwenzeka.Kodwa esi sakhiwo asilungile njengesakhiwo sokugquma umgubo.Ukudibanisa iimpawu zezakhiwo ezibini ze-insulation, siye sayila i-box-type insulation structure.
