2000 dhigirii yemagetsi yekudziya yemagetsi choto chekudziya chinhu: graphite kupisa chinhu

Iyo yekudziya ye2000 dhigirii yemagetsi yekudziya bhokisi choto inowanzogadzirwa negraphite, molybdenum kana MoSi2. Graphite zvinhu zvinowanzo shandiswa sezvinhu zvinodziya mumoto wepamusoro-tembiricha wevacuum, izvo zvinoita basa rakakosha mukuzivikanwa uye kushandiswa kweakakwira-tembiricha vacuum resistance furnaces uye high-tembiricha inodzivirira mamiriro ekunze. Yakawanda sei dhigirii iyo graphite inodziya element kupisa? Iyo graphite yekudziya element inoshandiswa muvacuum pane tembiricha ye2200 ℃, uye inogona kusvika 3000 ℃ mumhepo inoderedza kana inert mhepo.

Graphite heat element: Graphite heat element chinhu chinodziya chine graphite zvinhu semuviri wekudziya. Graphite ine hunhu hwekupikisa kupisa kwepamusoro, kuderera kwekuwedzera kwemafuta, uye kwakasimba kupisa kutyisa kuramba. Simba rayo rekugadzira rinowedzera nekukwira kwekushisa kwekupwanya pasi pe2500 ° C. Around 1700°C ndiyo yakanakisa, inodarika ese maokisisi nemasimbi. Graphite zvinhu zvine yakakwira kunyungudika uye yakaderera mhute pressure. Mamiriro ekunze echoto chevacuum ane yakaderera kusanganiswa kwekabhoni, iyo inozobatana neokisijeni uye mhute yemvura mune yasara gasi kugadzira kuchenesa, iyo inorerutsa zvakanyanya vacuum system uye inoderedza mutengo. Mukugadzira dhizaini yevacuum, chinhu chekudziya chinowanzo shandiswa pakupisa kupisa igraphite, inosanganisira tsigiro yemoto, chekuchengetedza kupisa, kubatanidza ndiro, kubatanidza nati, vent pombi uye zvichingodaro.

Nekuvandudzwa kwechiyero chemidziyo yekupisa yekupisa uye kudzika kwezvinodiwa zvemaitiro, tembiricha inodiwa yevacuum furnaces iri kuwedzera nekukwira. Zvechinyakare zvekudziisa zvinhu zvakaita sesilicon carbide rods uye silicon molybdenum tsvimbo haichakwanisa kuzadzisa zvinodiwa tembiricha, uye magirafu tsvimbo dzabuda sezvinodiwa nenguva.
