Graphite crucibles inozivikanwa nekusarudzika kwayo kupisa conductivity uye yakakwirira-tembiricha kuramba. Kudzikira kwavo kwakaderera kwekuwedzera kwemafuta kunovapa kusimba pakurwisa nekukurumidza kupisa uye kutonhora, zvichiita kuti vakwanise kukumbira zvikumbiro. Uyezve, kuramba kwavo kwakasimba kune corrosive acids uye alkaline solution, pamwe chete nekugadzikana kwemakemikari, zvinovasiyanisa mumaindasitiri akasiyana.
Nekudaro, kushandisa graphite crucibles kunoda kunyatsotarisisa kune chaiyo nhungamiro kuti ive nechokwadi chehupenyu hwavo hurefu uye kuita kwakakwana. Heano mamwe akakosha ekufunga nezvawo:
Pre-Use Precautions:
Kuongorora uye Kugadzirira Kwezvinhu: Nyatsoongorora zvinhu zvinoiswa mucrucible kune chero zvinhu zvinoputika. Paunenge uchiwedzera zvinhu, ita shuwa kuti zvakafanopiswa uye zvakaomeswa zvakakwana. Paunenge uchiunza graphite crucibles mukuita, chiyero chekuisa chinofanira kunge chiri zvishoma nezvishoma.
Kubata uye Kutakura: Shandisa maturusi akasarudzika ekutakura macrucibles, kudzivirira kukunguruka kwakananga pasi. Vabate nekungwarira panguva yekufambisa kudzivirira kukuvara kwekupenya, izvo zvinogona kukanganisa hupenyu hwecrucible.
Zvakatipoteredza: Chengetedza nharaunda yechoto yakaoma uye kudzivirira kuunganidzwa kwemvura. Usaisa zvinhu zvisingaenderane pedyo ne graphite crucibles kudzivirira chero kusawirirana kusingadiwi.
Crucible Installation uye Fixation:
YeGasi kana Mafuta Mafuro: Isa crucible pachigadziko, uchisiya imwe nzvimbo yekuwedzera pakati peiyo crucible pamusoro uye madziro evira. Shandisa zvinhu zvakaita semabhuroko emapuranga kana makadhibhokisi akaomarara kuti achengetedze panzvimbo. Rongedza chinopisa uye nzvimbo dzenozzle kuti ive nechokwadi chekuti murazvo wakananga mukamuri yekupisa, kwete zvakananga kuzasi kwecrucible.
Kune Rotary Furnaces: Shandisa zvidhinha zvekutsigira pamativi ese e crucible yekudururira spout kuti ichengetedze, pasina kunyanya kuomesa. Isa zvinhu zvakaita semakadhibhodi, anenge 3-4mm gobvu, pakati pezvidhinha zvekutsigira uye crucible kubvumira pre-kuwedzera.
YeMagetsi Emagetsi: Isa iyo crucible muchikamu chepakati chechoto chekupikisa, nehwaro hwayo zvishoma pamusoro pemutsara wepasi wezviyero zvekupisa. Nama mukaha pakati pe crucible pamusoro uye mupendero wechoto nezvinhu zvinodzivirira.
YeInduction Furnaces: Ita shuwa kuti crucible yakatarisana mukati meiyo induction coil kudzivirira kupisa kwenzvimbo uye kupaza.
Kuomerera kune idzi nhungamiro kunovimbisa kushandiswa kwakachengeteka uye kwakanaka kwegirafu crucibles, kuwedzera hupenyu hurefu hwema crucibles uye hunobudirira hwese mukushanda kwepamusoro-tembiricha.
Kuti uwane mamwe mirairo yakadzama nerutsigiro, vashandisi vanokurudzirwa kutarisa kune nhungamiro yemugadziri uye kuonana nenyanzvi dzeindasitiri.
