Munzvimbo yesimbi, chemistry, uye zvinhu sainzi, kusarudzwa kwekodzerocruciblezvinhu zvakakosha pakuona budiriro yeakasiyana maitiro, kubva pakupisa-tembiricha yesimbi alloying kusvika pakugadzirwa kwemhando yepamusoro ceramics nemagirazi. Kune akati wandei crucible zvinhu zviripo, imwe neimwe iine yakasarudzika seti yezvivakwa uye mabhenefiti. Ngationgororei zvakanakisa zvigadzirwa zvemacrucible mune zvakadzama zvakadzama:
Quartz Crucibles
Quartz crucibles, inowanzo gadzirwa kubva kune yakakwira-kuchena fused silica, inozivikanwa nehunhu hwayo hunoshamisa. Vanokunda mukudzivisa kupisa kwepamusoro, kutarisana nemigumisiro inoparadza yeasidhi nemabhesi, nekuchengetedza kugadzikana pasi pemamiriro ekupisa kwakanyanya. Aya ma crucibles anowana niche yavo mukunyungudutsa-yakachena simbi sesilicon, aluminium, uye iron. Uyezve, yavo yepamusoro yekupisa conductivity inovandudza kunyunguduka kushanda. Nekudaro, iyo premium mhando yequartz inouya pamutengo wepamusoro.
Ceramic Crucibles
Ceramic crucibles inosanganisira mapoka maviri makuru: aluminium oxide ceramics uye zirconium oxide ceramics. Aya macrucibles anopa zvakanakisa kupisa kupisa uye kugadzikana kwemakemikari, zvichiita kuti vave sarudzo dzakasiyana-siyana dzekunyungudutsa huwandu hwakawanda hwezvinhu, zvinosanganisira simbi, girazi, ceramics, nezvimwe. Zvakadaro, kupikisa kwavo kupisa kwakadzikira pane kwequartz crucibles, izvo zvinoita kuti zvinyatsokodzera zvinhu zvine mapoinzi ekunyungudika ari pasi pe1700 ° C.
Graphite Crucibles
Graphite crucibles ndiwo mahosi epamusoro-tembiricha, akanyanya-kudzvanywa nharaunda, anowanzo shanda sematurusi akakosha mumetallurgical uye makemikari ekutsvagisa. Aya macrucibles anowanikwa mumhando mbiri dzekutanga: natural graphite uye synthetic graphite. Natural graphite crucibles inozvitutumadza nekudzikama kwekupisa uye kusagadzikana kwekuora, yakanakira akasiyana-siyana ekushisa ekushandisa. Kune rumwe rutivi, ma-synthetic graphite crucibles anodhura-anoshanda asi anogona kunge akadzikisa zvishoma kugadzikana uye kusagadzikana kwemarara.
Metal Crucibles
Metal crucibles inogadzirwa kubva kuzvinhu zvakaita sesimbi isina tsvina, molybdenum, platinamu, nezvimwe. Iwo ndiwo ekuenda-kusarudzo kana uchibata nemidziyo ine yakasarudzika yakanyungudika mapoinzi kana yakatarisana neakanyanya acidic kana alkaline mamiriro. Metal crucibles inoratidza kuramba kwakasimba kune ngura uye kuchengetedza kunoshamisa kugadzikana kwemafuta. Zvakangodaro, kushandiswa kwavo kwakabatana nemutengo wepamusoro uchienzaniswa nezvimwe zvinhu zvinorovera.
Summary
TSarudzo yezvigadzirwa zvecrucible zvinofanirwa kufambiswa nechinhu chaicho chiri kugadziriswa uye nemamiriro ekunyungudika aripo. Imwe neimwe mhando yecrucible inopa yakasarudzika mabhenefiti uye zvisingakwanisi, uye kusarudza iyo chaiyo yakakosha kuti uwane inobudirira uye yemhando yepamusoro mhedzisiro muminda yesimbi, chemistry, uye zvinhu sainzi.
