I-silica crucible

Jonga iprimiyamuI-Silica Cruciblesyenzelwe ukunyibilika inyibiliki. Yethui-silicon carbide crucibleszibonelela nge-conductivity ephezulu ye-thermal, ukuxhathisa ukubola, kunye nobomi obude. Ifanelekile kwizicelo zokuphosa ubhedu kunye ne-aluminium.

IINGXAKI ZOKUSETYENZISWA KOKUSETYENZISWA KAKHULU

I-silica crucibles ibalasele kwiipropathi zazo ezikhethekileyo:

• I-conductivity ephezulu ye-thermal: Ukuhanjiswa kobushushu okukhawulezayo kunye okufanayo kuqinisekisa amaxesha okunyibilika ngokukhawuleza kunye nokusebenza okuphezulu.
• Ubomi benkonzo eyandisiweyo: I-silica crucibles ihlala ixesha elide le-2-5 ngaphezu kwe-graphite crucibles yodongwe, ukunciphisa ukuphindaphinda kokutshintshwa.
• Ukuxinana okuphantsi kunye nokuxinana okuphezulu: Ezi mpawu ziphucula amandla e-crucible, ukukhusela i-deformation kunye nokungaphumeleli kwesakhiwo kwiindawo ezitshisa kakhulu.

Ubungakanani obuncinci besilika

Izicelo zeLebhu kunye neziSeko zeMizi-mveliso

Kwindawo yelebhu,I-Silica Crubszisetyenziselwa amalinge amancinci kunye neenkqubo zokunyibilikisa. Ezi crucibles zikwasetyenziswa ngokubanzi kwizicelo zoshishino ezifana nokuphosa isinyithi, ngakumbi kwizinto ezifana nobhedu kunye ne-aluminium.I-silicon ye-carbide crucibleszithandwa kakhulu kwimisebenzi yomgangatho omkhulu ngenxa yokuqina kunye nokukwazi ukumelana nobushushu obugqithisileyo.

Ishushu kancinci

I-0 ° C-200 ° C: Ubushushu kancinci iiyure ezi-4

I-200 ℃ -300 ℃: Ubushushu kancinci ngeyure enye

I-300 ℃ -800 ℃: Ukushisa kancinci iiyure ezi-4

I-300 ℃ -400 ℃: Ukushisa kancinci ngeyure ezi-4

400℃-600℃: ukufudumeza ngokukhawuleza kunye nokugcinwa kweeyure ezi-2

Ukuthambisa

Emva kokuba isithando somlilo sivaliwe, ukufudumeza okucothayo kunye nokukhawulezayo kwenziwa ngokohlobo lweoli okanye isithando sombane ukuze kuqinisekiswe ukuba i-crucible ifikelela kwimeko engcono kakhulu ngaphambi kokusetyenziswa ngokusemthethweni.

Inkqubo yokusebenza

Xa usebenzisa i-silicon carbide crucible, iinkqubo zokusebenza kufuneka zilandelwe ngokungqongqo ukuze kuqinisekiswe ukuba ukusebenza kwayo kusetyenziswe ngokupheleleyo, ubomi bayo benkonzo bandiswa, ixabiso elingaphezulu lenziwe, kwaye izibonelelo eziphezulu zezoqoqosho zenziwa. Ukusebenza okugqwesileyo kunye nokuthembeka kwe-silicon carbide crucibles kuyenza ibe sisixhobo esiyimfuneko kwi-industrial smelting kunye neenkqubo zokuphosa.
