Mumakore achangopfuura, tekinoroji yekugadzira yemumbagraphite cruciblesyaita fambiro mberi huru. Havana kungobata chete macrucibles akaunzwa kunze kwenyika, asi mune dzimwe nguva akatoapfuura. Nekushandisa hunyanzvi hwekugadzira matekiniki uye kutsvaga zvemhando yepamusoro zvigadzirwa, magirafu crucibles zvino anogona kumira zvakanyanya nemamiriro ekunze nekugona kusingaenzaniswi.
Iwo makuru maficha eiyi mitsva yemagraphite crucibles hapana mubvunzo akakodzera kucherechedza. Kutanga, ivo vane high thermal conductivity, zvakanyanya kuderedza nguva yekunyunguduka, nekuda kwekushandiswa kwezvinhu zvakasvibirira zvakadai segraphite, iyo ine yakanakisa yekupisa conductivity. Uku kuwedzera kwekuita basa hakungochengetedze nguva nesimba chete, asiwo kunowedzera kugadzirwa mumaindasitiri.
Pamusoro pezvo, macrucibles aya ane hunyanzvi hwekupisa kupisa uye anogona kumira tembiricha kusvika 1200 kusvika 1600°C. Iyi yakasarudzika mhando inoita kuti ive yakanaka kune maapplication anoda kupisa kwakanyanya, senge simbi castings uye foundries. Iko kugona kutsungirira tembiricha yakanyanyisa kudaro pasina kukanganisa kuita ndeye shanduko yemitambo kune akawanda maindasitiri maitiro.
Chimwe chezvinhu zvinoshamisa zveiyi ma graphite crucibles ndiyo yakanakisa corrosion resistance. Ivo vanoratidza kuramba kwakanyanya kunyangwe pamberi pezvinhu zvinopisa zvakanyanya zvakanyungudutswa, kuve nechokwadi chekugara kwenguva refu uye kukwidziridzwa kuita. Uku kuramba kwecorrosion kunowedzera huwandu hwekushandiswa kweaya macrucibles, kunyanya mumaindasitiri emakemikari nesimbi.
Pamusoro pezvo, iyo yepamusoro yekupisa yekuvhundutsa kuramba inoita kuti ive yepamusoro kune zvakafanana zvigadzirwa. Graphite crucibles inoratidza elasticity pasi pekukurumidza kutonhora uye kudziya kutenderera, zvichiita kuti isanyanya kutapukirwa nekutsemuka. Uku kusimba kwepamusoro hakungonatsidzire kuchengetedzwa chete asiwo kunopa kukosha kwekuchengetedza mari nekuderedza kudiwa kwekugara kuchitsiva.
Graphite crucibles anoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kweakanakisa ekupisa conductivity uye yakakwirira tembiricha kuramba. Aya ma crucibles ane yakaderera coefficient yekuwedzera kwekupisa uye anoshingirira kushanduka kamwe kamwe kwekushisa. Ivo vanogona kumira nekukurumidza kupisa uye kutonhora pasina kutambudzika kukuru, kuve nechokwadi chekuita kwakakwana uye kuvimbika.
Graphite crucibles ine muenzaniso wekupokana kune acidic uye alkaline mhinduro, zvichiita kuti ive yakakosha mumarabhoritari uye zvidyarwa zvekugadzira makemikari. Kugadzikana kwavo kwakanakisa kumaitiro emakemikari kunoratidza kusimba kwavo uye vanogona kubata zvakasiyana-siyana zvemakemikari zvakachengeteka.
Iko kuumbwa kwegraphite crucible ndeye yakasikwa flake graphite seyakanyanya mbishi zvinhu. Inobatwa pamwe chete uchishandisa adhesive yakakosha inonzi plastic fire charcoal. Izvi zvakasiyana-siyana zvinosanganiswa zvinovimbisa kuti graphite crucibles inochengetedza kutendeseka kwemaitiro pasi pemamiriro ezvinhu akaoma, ichipa migumisiro inowirirana mune zvakasiyana-siyana zvekushandisa.
Kuuya kwema graphite crucibles anogadzirwa mudzimba hakungoratidzi budiriro yetekinoroji, asi zvakare kunotsigira kusimukira kwemaindasitiri emuno. Zvinogadzirwa munharaunda, zvemhando yepamusoro crucibles zvinodzikisira kuvimba nezvinotengwa kunze kwenyika uku ichipa mitengo inokwikwidza yeakasiyana mabhizinesi. Budiriro iyi inovhura nzira yekuti vanhu vakwanise kuzviriritira uye inosimbisa maindasitiri emunyika.
Muchidimbu, hutsva mukugadzira girafu crucible hwakasundidzira kune hurefu hutsva, kupfuura zvigadzirwa zvakatengwa kunze kwenyika maererano nekuita uye kusimba. Yakanakisa yekupisa conductivity, yakanakisa kupisa kupisa, corrosion kuramba uye kupisa kwekushomeka kwekushisa kunoita kuti ive yakakosha mumhando dzakasiyana dzemaindasitiri ekushandisa. Nekufambira mberi uku, indasitiri yepasi graphite crucible yakapa mupiro wakakura mukukura kweindasitiri yenyika uye kuzviriritira.
