Isithando somlilo se-Microwave sakhiwe ngokuyinhloko uhlelo lokuqapha, uhlelo lokulawula, ibhokisi lokufakwa ngaphakathi, ijeneretha ye-microwave, ibhokisi lokufudumeza kanye nethangi lokugcina igesi.Ibhokisi lokushisisa lenziwe ngepuleti lesibuko lensimbi engagqwali.Amanzi okupholisa angageleza kusemishi phakathi kwezingqimba ezimbili ze-stainless steel plate ukuze kufinyelele ukupholisa kwebhokisi lokushisisa.
1. Isimiso se-microwave sintering yezinto zobumba
Ukusabela kwezinto kuhhavini ye-microwave kungahlukaniswa ngezimo ezine: i-microwave reflection microwave transmission;ukumuncwa kwe-microwave;ukumuncwa ngokwengxenye kwe-microwave.Izinsimbi eziningi ziwela esigabeni sokuqala, kuyilapho zonke ingilazi nezinto zobumba ziwela ezigabeni ezintathu zokugcina.Lapho umzimba we-ceramic ufakwa ensimini ye-microwave, amandla amuncwa angavezwa nge-equation elandelayo:
P = (2π fε ) ( E2/ 2) tan δ，Lapho i-microwave ingena kokubalulekile, ukuqina kwayo kuncipha ngokujula kokungena.Ibanga ukusuka endaweni ebonakalayo ukuya ekunciphiseni ukuya ku-1/e yamandla e-microwave ichazwa njengokujula kokungena kwe-Dp ye-microwave:
3 l0
DP = π tan δ (ε r/ε 0) 1/ 2
8. 686
Lapho, P amandla e-microwave amuncwa umzimba we-ceramic;F imvamisa;ε iyinhlanganisela ye-dielectric engaguquki;λ 0 ubude begagasi be-microwave ku-vacuum;E ukushuba inkambu kagesi;I-tan δ iwuphawu lokulahlekelwa kwezitsha zobumba ze-dielectric;I-tangent yokulahlekelwa (isilinganiso sesici sokulahlekelwa ku-dielectric constant) ngokuvamile isetshenziselwa ukuveza ikhono lokuhlanganisa lento ku-microwave.Lapho liphakeme inani le-tangent yokulahlekelwa, kuqina amandla okuhlanganisa phakathi kwezinto ezibonakalayo ne-microwave.
2. Idizayini yesithando sokushisa esishisayo se-microwave
Isithando somlilo se-Microwave sakhiwe ngokuyinhloko uhlelo lokuqapha, uhlelo lokulawula, ibhokisi lokufakwa ngaphakathi, ijeneretha ye-microwave, ibhokisi lokufudumeza kanye nethangi lokugcina igesi.Ibhokisi lokushisisa lenziwe ngepuleti lesibuko lensimbi engagqwali.Amanzi okupholisa angageleza kusemishi phakathi kwezingqimba ezimbili ze-stainless steel plate ukuze kufinyelele ukupholisa kwebhokisi lokushisisa.Inzwa yezinga lokushisa esiyisebenzisayo yi-RAYR3I1MSCL2U ithemometha ye-infrared yenkampani ye-leitai yaseMelika.Uhlelo lokulawula lungabona ukulawula okwenziwa ngesandla nokulawula okuzenzakalelayo.Ukuze uvimbele ukuvalwa komnyango we-ovini we-microwave ngemuva kwesithando sokushisa i-microwave kusuka emnyango we-ovini nokuvuza ngaphandle kwezikhala phakathi komgodi, ngaphezu kokushisisa umnyango womlilo ekucubunguleni nasekukhiqizeni ukuqinisekisa ukunemba okuphezulu nokunemba komhlangano, thina umnyango we-oven microwave ofakwe eduze kwesakhiwo se-choke groove, lesi sakhiwo singanciphisa ngempumelelo ukuvuza kwe-microwave.Ukukhethwa, ukwakheka kwenkundla kanye nokufakwa kwejeneretha ye-microwave yizici ezibalulekile kuisithando somliloumklamo.
3. Ukukhetha ijeneretha ye-Microwave
I-Mag netron, i-Klystron ne-Gyrotron ngokuvamile zikhethwa kumishini yokushisisa i-microwave.Njengoba "inhliziyo" yemishini yokucwilisa i-microwave, ukukhetha kwayo kuzothinta ngqo ukusebenza kanye nezindleko zayo yonke imishini.Imvamisa esetshenziswa kakhulu kudivayisi ye-microwave sintering yile:
915 MHz, 2.45 GHz, 6 GHz, 28 GHz kanye 60 GHz, njll. Ngokuvamile, i-magnetron ingakhethwa njengejeneretha ye-microwave kumaza aphansi afana no-915 MHz no-2.45 GHz, 6 GHz ingakhethwa njengeshubhu elilawula isivinini, namaza aphezulu njenge-28 GHz kanye ne-60 GHz ingakhethwa njengekhoyili kazibuthe.
Njengoba imvamisa namandla amajeneretha e-microwave ahlukahlukene akhula, isilinganiso samanani sawo ($/ Watt) sizokhula kakhulu.Uma ijeneretha ye-microwave enamandla amakhulu idingeka ekwakhiweni, kutuswa ukusebenzisa imvamisa efanayo kanye nejeneretha yamandla aphansi ukuze kutholwe ngamandla amakhulu.
4.Umklamo we-insulation structure
Isakhiwo esivame ukusetshenziswa kakhulu sokufakwa kwesithando somlilo se-microwave sintering uhlobo lwempushana kanye nohlobo lwebhokisi.Isakhiwo se-powder engcwatshiwe sinezinzuzo zomphumela omuhle wokufakelwa.Kodwa-ke, lapho amasampula e-sintered ekushiseni okuphezulu, ukunamathela phakathi kwamasampula kanye nempushana engcwatshiwe kulula ukwenzeka.Ngemuva kokuthi amasampula esenziwe, ukuxhumana okuqondile kuzokwenzeka.Kodwa lesi sakhiwo asisihle njengesakhiwo se-powder engcwatshiwe.Ukuhlanganisa izici zezakhiwo ezimbili zokufakelwa, siklame ukwakheka kohlobo lwebhokisi.
