ubushushu obuphezulu bokunyibilika kwe-molybdenum crucible kwiziko

ubushushu obuphezulu ukunyibilika molybdenum crucible for eziko Umfanekiso Featured

Inkcazelo emfutshane:

I-molybdenum crucible enyibilikayo yobushushu obuphezulu sisitya esisetyenziselwa ngokukodwa izicelo zobushushu obuphezulu, ngakumbi kwiziko kunye nezinye izixhobo zokunyanga ubushushu.I-Molybdenum yakhethwa ngenxa yendawo ephezulu yokunyibilika kunye nokumelana nomhlwa, okwenza ukuba ifanele ukuphatha isinyithi esityhidiweyo kunye nezinye izinto ezinobushushu obuphezulu.Ezi crucibles ziqhele ukusetyenziswa kumashishini afana ne-metallurgy, ukwenza iglasi kunye nophando lwezixhobo zokushisa eziphezulu.

Yintoni i-crucible yobushushu obuphezulu bokunyibilika?

I-crucible crucible melting crucible yinqanawa ekhethekileyo eyenzelwe ukumelana nokushisa okukhulu kwaye iqulethe izinto eziphathekayo kwindawo etyhidiweyo kumaqondo aphezulu.Ezi crucibles ngokuqhelekileyo zenziwe ngezinto ezineendawo eziphezulu zokunyibilika kunye nokuzinza okuphezulu kwe-thermal, njengentsimbi ephikisayo efana ne-molybdenum kunye ne-tungsten okanye i-ceramics ezifana ne-alumina okanye i-zirconia.Ngokuqhelekileyo zisetyenziswa kwiinkqubo zoshishino ezifana nokuphosa isinyithi, ukuveliswa kweglasi kunye nophando lwezixhobo zokushisa eziphezulu ezifuna ukugcinwa kwezinto ezityhidiweyo kumaqondo aphezulu.Ezi crucibles ziyinxalenye ebalulekileyo yokushisa okuphezulu kunye nezinye izixhobo zonyango lokushisa.

Lithini iqondo lobushushu leziko lomlilo?

Amaqondo obushushu eziko lomlilo anokwahluka ngokuxhomekeka kwisicelo esithile kunye nezinto ezicutshungulwayo.Iifurnas zeCrucible zenzelwe ukufikelela kumaqondo aphezulu okushisa ukunyibilika kunye nokucutshungulwa kwezinto ngaphakathi kwe-crucible.Uluhlu lwamaqondo obushushu eziko elivuthululwayo lunokwanda ukusuka kumakhulu ambalwa amadigri ngokukaCelsius ukuya kuthi ga kwi-1000 ngokukaCelsius, kuxhomekeke kuyilo kunye nokusetyenziswa okucetyiweyo kweziko.

Zeziphi iibhola ezinendawo yokunyibilika ephezulu?

I-crucibles ezenziwe ngezinto ezithile zineendawo eziphezulu zokunyibilika kwaye zifanelekile ukusetyenziswa kwizicelo zokushisa okuphezulu.Ezinye iimathiriyeli ezisetyenziselwa ukunyibilika okuphezulu kwi-crucibles ziquka:

1. I-Tungsten: I-Tungsten crucibles ineendawo eziphezulu kakhulu zokunyibilika, ezenza ukuba zilungele ukusetyenzwa kwezixhobo kwiqondo lokushisa eliphezulu kakhulu, ezifana nokuveliswa kweekristale zesafire kunye nezinye iinkqubo eziphezulu zokushisa.

2. I-Molybdenum: I-Molybdenum crucibles nayo ine-high melting point kwaye isetyenziswa ngokuqhelekileyo kwizicelo ezibandakanya isinyithi esityhidiweyo, i-glass melting, kunye nophando lwezixhobo zokushisa eziphezulu.

3. I-Alumina (i-aluminium oxide): I-aluminium crucibles iyaziwa ngokuchasana nokushisa okuphezulu kwaye isetyenziswa ngokuqhelekileyo kwi-laboratory kunye nezicelo zoshishino ezibandakanya izinto eziphezulu zokushisa.

4. I-Zirconia: I-Zirconia crucibles inokumelana nokushisa okuphezulu kwaye isetyenziswe kwizicelo ezifana nokuchithwa kwetsimbi kunye nokushisa okuphezulu.

Ezi zixhobo zikhethwe ukwakhiwa kwe-crucible ngenxa yokukwazi ukumelana nokushisa okukhulu kunye nokugcina ingqibelelo yesakhiwo kwiqondo lokushisa eliphezulu.
