Crucibles inouya mumhando dzakasiyana siyana uye zvakatemwa, zvichipa huwandu hwakasiyana hwemashandisirwo pasina kudzikiswa nechiyero chekugadzira, saizi yebatch, kana akasiyana ezviyero zvinonyungudika.Uku kuchinjika kunovimbisa kuchinjika kwakasimba uye kunovimbisa kuchena kwezvinhu zviri kunyungudutswa.
Mirayiridzo Yekushandisa:
Mushure mekushandisa, isa crucible munzvimbo yakaoma uye udzivise kutarisana nemvura inonaya.Usati waishandisa zvakare, zvishoma nezvishoma kupisa crucible kusvika 500 degrees Celsius.
Paunenge uchiwedzera zvinhu kune crucible, dzivisa kuwandisa kudzivirira simbi kubva pakuwedzera uye kupaza iyo crucible nekuda kwekuwedzera kwekupisa.
Paunenge uchibvisa simbi yakanyungudutswa kubva kune crucible, shandisa chipunu pese pazvinogoneka uye kuderedza kushandiswa kwembato.Kana mbariro kana mamwe maturusi achidikanwa, ita shuwa kuti anoenderana nechimiro che crucible kudzivirira yakawandisa yenzvimbo simba uye kuwedzera hupenyu hwayo.
Hupenyu hwe crucible hunokanganiswa nekushandiswa kwayo.Dzivisa kutungamira ma-high-oxidation mirazvo yakananga pane crucible, sezvo izvi zvinogona kukonzera kukurumidza oxidation ye crucible material.
Crucible Manufacturing Materials: Zvigadzirwa zvekugadzira zve crucibles zvinogona kupfupikiswa mumhando mitatu mikuru: crystalline natural graphite, plastic refractory ivhu, uye calcined hard kaolin-like materials.Kubva 2008, yakakwirira-tembiricha inodzivirira yekugadzira zvinhu zvakaita sesilicon carbide, alumina corundum, uye silicon iron zvakashandiswawo semagadzirirwo ezvigadzirwa zvemacrucibles.Zvishandiso izvi zvinosimudzira zvakanyanya kunaka, density, uye kusimba kwemagetsi ezvigadzirwa zvecrucible.
Zvishandiso: Crucibles inowanzoshandiswa ku:
Kupisa zvinhu zvakasimba
Evaporation, concentration, kana crystallization yemhinduro (kana midziyo inoputika isingawanikwe, crucibles inogona kushandiswa pachinzvimbo)
Mazano Akakosha Ekushandisa:
Crucibles inogona kupiswa zvakananga, asi haifanirwe kukurumidza kutonhora mushure mekupisa.Shandisa mbambo dzekurovera kuti udzibate kana dzichipisa.
Isa crucible pane yevhu katatu panguva yekupisa.
Gadzirisa zviri mukati kana zvichibuda uye shandisa kupisa kwasara kwepedyo-kupedzwa kuoma.
Kurongeka kweCrucibles: Crucibles inogona kukamurwa zvakanyanya muzvikamu zvitatu: graphite crucibles, ivhu crucibles, uye simbi crucibles.Mukati mechikamu che graphite crucible, pane ma graphite crucibles akajairwa, akasiyana-shaped graphite crucibles, uye high-purity graphite crucibles.Imwe neimwe mhando yecrucible inosiyana mukuita, mashandisiro, uye mamiriro ekushanda, zvichitungamira kune mutsauko wezvakagadzirwa, nzira dzekugadzira, maitiro ekugadzira, uye maratidziro echigadzirwa.
Zvinotsanangurwa uye Kuverengera: Crucible specifications (masaizi) anowanzo kuratidzwa nenhamba dzakatevedzana.Semuenzaniso, #1 crucible inogona kubata vhoriyamu ye1000g yendarira uye inorema 180g.Kunyunguduka kwesimbi dzakasiyana kana alloys kunogona kuverengerwa nekuwanza reshiyo yecrucible yevhoriyamu-ku-huremu nesimbi yakakodzera kana alloy coefficient.
Mashandisirwo Akanyanya: Nickel crucibles akakodzera kunyungudusa samples dzine NaOH, Na2O2, Na2CO3, NaHCO3, uye KNO3 mune alkaline solvents.Zvakadaro, hazvina kukodzera kunyungudusa samples dzine KHSO4, NaHS04, K2S2O7, kana Na2S2O7, kana zvimwe zvinonyungudutsa zvine acidic, pamwe nealkaline sulfides ine sarufa.
Mukupedzisa, macrucibles anopa akasiyana siyana ekushandisa mumaindasitiri akasiyana, uye nekutevera mashandisiro akakodzera nhungamiro, hupenyu hwavo hurefu uye kugona kwavo kunogona kukwidziridzwa.
