Isingeniso somkhiqizo
Le furnace ye-vacuum hot pressing yakhelwe ngokukhethekile inqubo yokubilisa ye-vacuum hot pressing yezinto eziphezulu ezisebenza kahle ezifana ne-ceramics, i-composite ceramics, izinto eziqinile kakhulu, njll. Lezi zinsiza zisebenzisa izinto zokushisa ezisekelwe ku-graphite noma ezisekelwe ku-metal resistor, zihlanganiswe nokushayela kwe-hydraulic cylinder phezulu./Uhlelo lokucindezela olungaphansi, olwenza ukuhlanganiswa kwezinto ezicindezelweyo ngaphansi kwezinga lokushisa eliphezulu nomfutho omkhulu. Ngokuvimbela ukusabela kwe-oxidation endaweni ye-vacuum, ngenkathi kusetshenziswa ingcindezi yangaphandle ukusheshisa ukuxhunyaniswa kwamagranule ezinto kanye nokukhula kwamagranule, kunciphisa ngempumelelo izimbobo kanye nemingcele ye-grain, kuthuthukisa ukudluliswa kwezinto, kubangele ukuncipha kwevolumu ye-green body nokwanda okukhulu kwedensithi, ekugcineni kudale i-sintered body eyenziwe ngama-polycrystals acindezelweyo enomqeqeshi omuhle kakhulu, ukuhlangabezana nezidingo zokubunjwa kwezinto ezinembayo ephezulu namandla aphezulu.
Izici zobuchwepheshe
Uhlelo lokushisa olusebenzayo: Kusetshenziswa i-graphite noma ukushisa okumelana ne-metal, izinga lokushisa eliphezulu lokusebenza lingafinyelela ku-2200℃(Kuya ngento yokushisa), isivinini sokukhuphuka siyashesha, ukufana kwezinga lokushisa le-furnace kuhle.
Indlela yokucindezela kabili: I-head yokucindezela, ehambiswa yi-cylinder kawoyela engenhla noma engaphansi, yenza ukucindezela kwe-uniaxial, uhla lokucindezela lungalungiswa (inani elijwayelekile5~50amathani), ukuqinisekisa ukuthi inqubo yokucindezela izinzile futhi ilawuleka.
Imvelo ye-vacuum ephezulu: Ifakwe iyunithi ye-vacuum esebenza kahle kakhulu, i-vacuum ephezulu ingafinyelela ku6.67×10⁻³ Pa, ukuvimbela ngempumelelo ukubola kwezinto, ukukhipha umoya, nokuthuthukisa ukuhlanzeka kokubilisa.
Ukulawula izinga lokushisa nokucindezela okunembayo: KusebenzisaPIDI-instrument yokulawula izinga lokushisa nohlelo lokubuyisela emuva lwe-pressure sensor, ukufeza izinga lokushisa-Ingcindezi-Ukunquma okuzenzakalelayo kwe-curve yokubilisa okuxhunywe nesikhathi.
Idizayini yokuvikela ephephile: Ine-furnace shell enesendlalelo sokupholisa amanzi, i-alamu yokushisa ngokweqile nokucindezela ngokweqile, kanye nokukhiya okungaphazamiseki kokugeleza kwamanzi nokunqamuka kukagesi, ukuqinisekisa ukusebenza okuphephile nokuthembekile kwemishini isikhathi eside.
Isakhiwo esiyimodular: Umzimba we-furnace, uhlelo lwe-vacuum, uhlelo lwe-hydraulic, nekhabhinethi yokulawula ugesi zihlukaniswe futhi zihlanganiswe, okwenza kube lula ukugcinwa nokunwetshwa kwemisebenzi.
