Iimpawu ze-silicon carbide crucible

I-silicon ye-carbide crucibleidume ngokuxinana kwevolumu ephezulu, ukumelana nobushushu obuphezulu, ukuhanjiswa kobushushu okukhawulezayo, iasidi kunye nokumelana nokutyiwa kwealkali, amandla aphezulu obushushu obuphezulu, kunye nokuxhathisa okuqinileyo kwe-oxidation. Ubomi benkonzo ye-silicon carbide crucible ngamaxesha angama-3-5 ubude kune-graphite crucible eqhelekileyo. Yeyona ndawo ifanelekileyo yesixhobo sokutshiza ngomgubo oxutyiweyo, ukunyibilikiswa kwesinyithi kunye nezinye iikloni zamashishini kwi-metallurgy, kushishino lweekhemikhali, iglasi kunye namanye amacandelo.

Xa usebenzisa i-silicon carbide crucibles, kukho izinto ezimbalwa ekufuneka uzigcine engqondweni:

1. Musa ukugcwalisa i-silicon carbide crucible igcwele kakhulu ngokunyibilika ukuthintela ukutshiza, kwaye uvumele umoya ukuba ungene kwaye uphume ngokukhululekileyo ukubangela ukusabela okunokwenzeka kwe-oxidation.
2. I-silicon carbide crucible inomzantsi omncinci kwaye ngokubanzi kufuneka ibekwe kunxantathu wodongwe ukufudumeza ngokuthe ngqo. I-crucible inokubekwa phantsi okanye ifakwe kwi-tripod yentsimbi, kuxhomekeke kwiimfuno zovavanyo.
3. Emva kokufudumeza, musa ukubeka i-silicon carbide crucible ngokukhawuleza kwitafile yentsimbi ebandayo ukunqanda ukuqhekeka ngenxa yokupholisa ngokukhawuleza. Ngokufanayo, musa ukuyibeka phezu kwetafile ngeplanga ukuze uphephe ukuyitshisa okanye ubangele umlilo. Indlela echanekileyo kukuyibeka kwi-iron tripod ukuze iphole ngokwendalo okanye ibekwe kumnatha we-asbestos ukuze iphole kancinci kancinci.

Isishwankathelo, iipropathi ezikhethekileyo ze-silicon carbide crucibles zenza ukuba zibe yimfuneko kwiinkqubo ezahlukeneyo zemizi-mveliso, kwaye ukulandela izikhokelo zokusetyenziswa ezichanekileyo ziqinisekisa ubomi obude kunye nokhuseleko.
