Murfin dumama microwave galibi ya ƙunshi tsarin kulawa, tsarin sarrafawa, akwatin rufewa, janareta na microwave, akwatin dumama da tankin ajiyar gas.Akwatin dumama an yi shi da farantin madubi na bakin karfe.Ruwa mai sanyaya na iya gudana a cikin sanwici tsakanin yadudduka biyu na bakin karfe don cimma sanyin akwatin dumama.
1. Ka'idar microwave sintering na yumbu kayan
Ana iya raba martanin kayan zuwa microwave zuwa yanayi guda hudu: watsawar microwave tunani;shawar microwave;wani bangare na sha microwave.Yawancin karafa sun fada cikin rukuni na farko, yayin da duk kayan gilashi da yumbura suka fada cikin rukuni uku na ƙarshe.Lokacin da aka sanya jikin yumbura a cikin filin microwave, ana iya bayyana ikon da aka sha ta hanyar lissafin mai zuwa:
P = (2π fε ) ( E2/ 2) tan δ， Lokacin da microwave ya shiga cikin kayan, ƙarfinsa yana raguwa tare da zurfin shiga.Nisa daga saman kayan zuwa attenuation zuwa 1/ e na makamashin microwave an ayyana shi azaman zurfin shigar Dp na microwave:
3 da 0
DP = π tan δ (ε r/ε 0) 1/ 2

Inda, P shine ikon microwave wanda jikin yumbu ke sha;F shine mitar;ε shine m dielectric akai-akai;λ 0 shine tsayin daka na microwave a cikin injin;E shine tsananin wutar lantarki;tan δ shine asarar tangent na dielectric yumbu;Matsakaicin hasara (rabo na asarar hasara zuwa dielectric akai-akai) yawanci ana amfani dashi don bayyana iyawar haɗakarwa na kayan abu zuwa microwave.Mafi girman ƙimar tangent asarar shine, ƙarfin haɗin gwiwa tsakanin abu da microwave shine.
2. Zane na microwave high zafin jiki dumama makera
Murfin dumama microwave galibi ya ƙunshi tsarin kulawa, tsarin sarrafawa, akwatin rufewa, janareta na microwave, akwatin dumama da tankin ajiyar gas.Akwatin dumama an yi shi da farantin madubi na bakin karfe.Ruwa mai sanyaya na iya gudana a cikin sanwici tsakanin yadudduka biyu na bakin karfe don cimma sanyin akwatin dumama.Ma'aunin zafin jiki da muke amfani da shi shine RAYR3I1MSCL2U infrared thermometer na kamfanin leitai na Amurka.Tsarin sarrafawa na iya gane kulawar hannu da sarrafawa ta atomatik.Domin ya hana a cikin obin na lantarki tanda kofa rufe bayan obin na lantarki dumama makera daga tanda kofa da yayyo daga cikin gibba tsakanin rami, ban da dumama tanderun kofa a cikin aiki da kuma masana'antu don tabbatar da high girma madaidaici da kuma taro daidaici, mu a cikin. Ƙofar tanda microwave shigar a kusa da tsarin tsagi na shaƙa, wannan tsarin zai iya rage yawan zubar da microwave yadda ya kamata.Zaɓin, ƙirar filin da rufin janareta na microwave sune mahimman abubuwan da ke cikinsintering makerazane.
3. Zaɓin janareta na microwave
Mag netron, Klystron da Gyrotron gabaɗaya ana zaɓar su a cikin na'urorin dumama microwave.A matsayin "zuciya" na kayan aikin lantarki na lantarki, zabinsa zai shafi kai tsaye da aiki da farashin kayan aiki duka.Mitar da aka saba amfani da ita a cikin na'urar sintiri ta microwave shine:
915 MHz, 2.45 GHz, 6 GHz, 28 GHz da 60 GHz, da dai sauransu. Gabaɗaya, ana iya zaɓar magnetron azaman janareta na microwave don ƙananan mitoci kamar 915 MHz da 2.45 GHz, 6 GHz za a iya zaɓar azaman bututu mai sarrafa saurin gudu, kuma mafi girma mitoci. kamar 28 GHz da 60 GHz ana iya zaɓar su azaman na'urar maganadisu.
Yayin da mitar da ƙarfin na'urorin injin microwave daban-daban ke ƙaruwa, ƙimar farashin su ($/ Watt) zai ƙaru sosai.Idan ana buƙatar janareta na microwave mai ƙarfi a cikin ƙira, ana ba da shawarar yin amfani da mitar guda ɗaya da ƙananan janareta don samun ta ikon superposition.
4.Design na tsarin rufewa
Tsarin rufin da aka fi amfani da shi a cikin tanderu sintering tanderun shine nau'in foda da nau'in akwatin binne.Buried foda rufi tsarin yana da abũbuwan amfãni daga mai kyau rufi sakamako.Duk da haka, lokacin da aka yi amfani da samfurori a yanayin zafi mafi girma, mannewa tsakanin samfurori da foda da aka binne yana da sauƙin faruwa.Bayan samfuran sun ɓata, lamba kai tsaye za ta faru.Amma wannan tsarin ba shi da kyau kamar tsarin rufe foda da aka binne.Haɗuwa da halaye na sifofi guda biyu, mun tsara tsarin suturar nau'in akwatin.
