Silicon carbide cruciblechinhu chakakosha chekunyungudutsa muindasitiri yemetallurgical. Nekuda kwekunaka kwayo kwepamusoro tembiricha kuramba uye kupisa conductivity, inoshandiswa zvakanyanya mukunyungudutsa simbi kwakasiyana-siyana uye kuita kwemakemikari. Nekudaro, kuti ive nechokwadi chekuita kwakaringana panguva yekushandiswa, silicon carbide crucibles inoda kuve yakanyatso preheated.
Preheating matanho esilicon carbide crucible
Silicon carbide crucibles inoda kutarisirwa kwakakosha panguva ye preheating process kudzivirira matambudziko akadai sekuwedzera kwekupisa, kudzika kwepasi, delamination kana kuputika kunokonzerwa nekusarira mwando. Matanho chaiwo ndeaya anotevera:
Kubika kwekutanga: Bika muchoto usingawedzeri zvinhu, uye chengetedza tembiricha kweanopfuura maawa makumi maviri nemana. Munguva iyi, tenderedza crucible nguva nenguva kuti uone kupisa kwakafanana uye kubvisa zvachose hunyoro kubva kumadziro ecrucible.
Zvishoma nezvishoma kupisa:
Kutanga preheat the crucible kusvika 150 kusvika 200 degrees Celsius uye bata kweawa imwe.
Zvadaro, wedzera tembiricha pamwero we150 degrees Celsius paawa kusvikira tembiricha yepamusoro yasvika. Munguva iyi, dzivisa kusiya madziro anorovera patembiricha ari pakati pe315 ne650 madhigirii celsius kwenguva yakarebesa, sezvo crucible ichaita oxidize nekukurumidza mune ino tembiricha renji, ichipfupisa hupenyu hwayo uye ichideredza yayo yekupisa conductivity.
Kurapa kwekushisa kwepamusoro:
Mushure mekunge preheating yapedzwa, kunze kwekunge crucible ichiratidzwa kune yakanyorovesa nharaunda zvakare, haidi kuti igadzirwe zvakare uye inogona kuramba ichishandiswa.
Mushure mekunge preheating yapera, kurumidza kusimudza tembiricha kusvika 850 ~ 950 madhigirii celsius, chengeta ichidziya kwehafu yeawa usingawedzeri zvinhu, wozotonhorera kusvika kune yakajairika tembiricha yekushanda uye tanga kuwedzera zvinhu. Kurapa uku kunogona kunyatso kuwedzera hupenyu hwebasa recrucible.
Dzimwe preprocessing nzira
Pamusoro pematanho ekutanga ekupisa, nzira dzinotevera dzinogona kushandiswa zvakare:
Preheat padivi peanopisa mafuta: Kuisa crucible padivi peanopisa mafuta kunogona kubatsira kubvisa unyoro.
Kupisa marasha kana huni: Kupisa marasha kana huni mucrucible kunogona kubatsira kubvisa unyoro.
Kusarudza saizi chaiyo yecrucible
Silicon carbide crucible dimensions inosiyana zvichienderana nemugadziri uye chaiyo application. Naizvozvo, kana uchisarudza, ndapota tarisa kune yakatarwa chigadzirwa kana bvunza mutengesi kuti uwane ruzivo rwechokwadi. Kusarudza crucible chaiyo zvichienderana nezvido zvako kunogona kuvandudza kugadzirwa kwakanaka uye kunaka kwechigadzirwa.
Nekutevera kwakaringana preheating uye maitiro ekugadzirisa, silicon carbide crucibles inogona kuwedzera mashandiro avo uye kuwedzera hupenyu hwavo hwesevhisi, ichipa vimbiso yakavimbika yekugadzira kwako maitiro.
Graphite Crucible User Guide
Graphite crucibles zvakare inoshandiswa zvakanyanya mukupisa tembiricha kuyedza uye kugadzirwa kwemaindasitiri. Kuramba kwayo kwekushisa kwakanyanya, corrosion resistance, uye yakanaka yekupisa conductivity inoita kuti ive yakanakira kuyedza kwakawanda uye maitiro ekugadzira. Kuti uve nechokwadi chekuita kwakanyanya uye hupenyu hurefu hwebasa regirafu crucible, matanho anotevera anofanirwa kutariswa panguva yekushandiswa:
Sample kuiswa
Solid sample: Govera zvakaenzana chinhu chekuyedza kana mbishi mune girafu crucible kudzivirira kupisa kwenzvimbo kana kusasa.
Liquid samples: Shandisa inodonhedza kana imwe diki-sampling chishandiso kudonhedza mvura mucrucible kudzivirira kupuruzira kana kusvibisa kunze kweiyo crucible.
kupisa kushanda
nzira yekudziya:
Shandisa magetsi ekudziya midziyo, infrared radiation kudziyisa kana dzimwe nzira dzakakodzera dzekudziya kupisa girafu crucible.
Dzivisa kupisa kwakananga nemurazvo wakashama. Nekuti high-purity graphite ine high thermal conductivity, kupisa kwakananga nemurazvo wakavhurika kunogona kuita kuti crucible iparare kana kutsemuka.
Kupisa kumhanya:
Chengetedza mwero wekudziya wakakodzera kudzivirira kukuvadza crucible nekuda kwekushanduka kwekushisa kamwe kamwe.
Rongedza chinzvimbo uye simba remudziyo wekudziya kuti uve nechokwadi chekuti crucible inopisa zvakaenzana.
Zvekungwaririra
Dzivisa kusangana nemurazvo wakananga: Paunenge uchidziya, dzivirira kutarisana nemurazvo kuti usasiya mavanga matema pazasi pe crucible kana kukonzera kumwe kukuvadza.
Kudzora tembiricha: Graphite crucible inonzwa nekushanduka kwekushisa, saka tembiricha yekudziya inofanirwa kudzorwa panguva yekushandiswa kudzivirira kuputika kwecrucible nekuda kwekunyanya kupisa kana kuderera zvakanyanya.
Kucheneswa kwezvakatipoteredza uye kuchengetedzeka: Chengetedza nharaunda yakatenderedza yakachena uye kudzivirira kukuvadzwa kune graphite crucible nekuda kwekukanganisa kana kudonha kubva pakakwirira.
Professional data rutsigiro
Thermal conductivity: Thermal conductivity ye-high-purity graphite crucible inenge 100-300 W/m·K, iyo inoigonesa kukurumidza kuendesa kupisa pakupisa kwakanyanya uye kuderedza kushushikana kwekushisa gradient pane crucible.
Kushanda tembiricha: Graphite crucible ine yakanakisa kupisa tembiricha kuramba, yakanyanya tembiricha yekushanda inogona kusvika 3000 ° C, uye inoshandiswa zvakanyanya mumhepo inert.
Oxidation resistance: Kana ichishandiswa pakupisa kwepamusoro mumhepo, pamusoro pe graphite crucible inowanzoita oxidation. Matanho ekudzivirira akadai sekushandisa anti-oxidation coating kana kushandisa inert gasi kudzivirira kunofanirwa kutorwa.
Kunyatsoomerera kune dziri pamusoro nzira uye dziviriro dzinogona kuve nechokwadi chekushanda kwepamusoro uye hupenyu hurefu hwemagraphite crucibles uye.silicon carbide crucibles, nokudaro kuvandudza kuvimbika uye kunaka kwekuedza nekugadzirwa.
