Chifukwa Chiyani Mumayanjana Nafe?

Mukatisankha, mumapeza zambiri kuposa zomwe mumapeza - mumapeza mnzanu.

• ukatswiri: Zaka zambiri zazaka zambiri pantchito yoyambira.
• Kusintha Mwamakonda: Mayankho opangidwa kuti akwaniritse zosowa zanu zenizeni.
• Thandizo: Kuyambira kusankha mpaka kukhazikitsa, tili nanu njira iliyonse.

Zofunika:

ZathuCylindrical Crucibleamapangidwa kuchokera ku isostatically akanikizidwa silicon carbide graphite, zinthu zomwe zimapereka kukana kutentha kwambiri komanso kutenthetsa bwino kwambiri, kupangitsa kuti ikhale chida chofunikira popanga ntchito zosungunulira mafakitale.

1. Silicon Carbide (SiC): Silicon carbide imadziwika chifukwa cha kuuma kwake kwambiri komanso kukana kwambiri kuvala ndi dzimbiri. Ikhoza kupirira kutentha kwakukulu kwa mankhwala, kupereka kukhazikika kwapamwamba ngakhale pansi pa kupsinjika kwa kutentha, zomwe zimachepetsa chiopsezo cha kusweka panthawi ya kusintha kwadzidzidzi kutentha.
2. Natural Graphite: Natural graphite imapereka matenthedwe apamwamba kwambiri, kuwonetsetsa kufalikira kwachangu komanso kofananako kutentha mu crucible yonse. Mosiyana ndi ma graphite crucibles opangidwa ndi dongo, cylindrical crucible yathu imagwiritsa ntchito graphite yachilengedwe yoyera kwambiri, yomwe imapangitsa kuti kutentha kuzitha komanso kumachepetsa kugwiritsa ntchito mphamvu.
3. Isostatic Pressing Technology: crucible imapangidwa pogwiritsa ntchito kukanikiza kwapamwamba kwa isostatic, kuwonetsetsa kachulukidwe ka yunifolomu popanda chilema chamkati kapena chakunja. Tekinoloje iyi imakulitsa mphamvu ndi kukana kwa crucible, kukulitsa kukhazikika kwake m'malo otentha kwambiri.
   1. Kukana Kutentha Kwakukulu: Chotengera choyenera chosungunula mkuwa chiyenera kupirira kutentha kopitilira 1,600°C. Ma graphite silicon carbide crucibles amadziwika chifukwa cha kukana kwawo kutentha kwambiri, kuwonetsetsa kuti amakhalabe osasunthika panthawi yosungunuka.
   2. Kutentha Kwabwino Kwambiri: Kutentha koyenera ndikofunikira kuti mkuwa usungunuke bwino. Zida za graphite silicon carbide zimalola kufalitsa kutentha kwachangu komanso kofanana, kuwongolera bwino kusungunula komanso kuchepetsa nthawi yokonza.
   3. Kukaniza kwa Corrosion: Njira zosungunula mkuwa nthawi zambiri zimayika zinthu za acidic kapena zamchere. Chophimba chapamwamba kwambiri chopangidwa kuchokera ku graphite silicon carbide chimakhala ndi kukana kwamphamvu kwa dzimbiri, komwe kumakulitsa moyo wake wautumiki ndikuchepetsa chiwopsezo choipitsidwa ndi chitsulo chosungunuka.
   4. Mphamvu zamakina: Kusunga umphumphu wamapangidwe pansi pa kutentha kwakukulu ndikofunikira. Ma crucibles abwino kwambiri amkuwa amakhala ndi mphamvu zamakina apamwamba kwambiri, kuwonetsetsa kuti samapunduka kapena kuwonongeka pakatentha kwambiri.
   5. Kukhazikika Panthawi Yogwiritsa Ntchito: Kukhazikika kwamankhwala ndi thupi ndikofunikira kuti tipewe kuchitapo kanthu kosafunika pakati pa crucible ndi mkuwa wosungunuka. Kukhazikika kumeneku kumathandiza kuti chitsulo chosungunulacho chikhale choyera, chomwe chili chofunika kwambiri popanga zinthu zamkuwa zamtengo wapatali.
