Iintsimbi zegraphitezisetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kwaye kubalulekile ukwenza uhlolo olucokisekileyo kwaye ukhethe ngononophelo izinto ezifanelekileyo.Nazi ezinye izikhokelo zokuhlola kunye nokukhethaiicrucibles zegraphite:
Ngaphambi kokusebenzisa Ukuhlola: Ngaphambi kokusebenzisa i-i-graphite crucible, khangela iintanda kunye nomonakalo.Ngokuqinisekileyo akukho ziqhekeko ezibonakalayo, kuyimfuneko ukutshisa i-crucible kwiqondo lokushisa elingaphezulu kwe-600 ° C ukuqinisekisa ukomisa ngokucokisekileyo.
Ukulungiswa kokusingqongileyo: Qinisekisa ukuba akukho manzi aqokelelweyo kwiziko okanye emhadini apho i-crucible iya kufakwa khona.Kwakhona, gcina izinto ezingahambelaniyo kude nommandla we-graphite crucible.
Ukuphathwa kweMathiriyeli: Thatha amanyathelo okhuseleko xa uphethe izixhobo zesithando somlilo.Qinisekisa ukuba imathiriyeli ayiqhushumba kwaye ifudunyeziwe yaza yomiswa ngokufanelekileyo.Xa ukongeza izinto kwi-graphite crucible, yenza ngokukhawuleza kwaye ngokukhawuleza.
Kubalulekile ukulandela ezi zikhokelo zokuhlola ukukhusela ubungozi obunokubakho kunye nokuqhuma xa usebenzisa ii-graphite crucibles.
I-Graphite crucibles isetyenziselwa ukufudumeza izinto zokulinga.Zinobukhulu obuhlukeneyo kunye neentlobo, ezivumela ukukhethwa kwe-crucible efanelekileyo ngokusekelwe kwisixa, uhlobo, kunye nokwandiswa kwe-thermal yezinto ezifudumalayo.Kubalulekile ukunqanda ukuzalisa ngokugqithisileyo i-crucible ngezinto ezifudumalayo, njengoko kunokukhokelela kwiingozi ngexesha lovavanyo kwaye kube nefuthe elibonakalayo kubomi be-crucible.Ukongezelela, xa i-crucible ishushu kwiqondo lokushisa eliphezulu, ngokuqhelekileyo malunga ne-400-500 ° C, kubalulekile ukuyiphatha ngokuqaphela kwaye ugweme ukuyiphatha ngezandla ezingenanto njengoko kunokubangela ukutshisa okukhulu.
Ukukhethwa kwezinto eziphathekayo kwi-graphite crucibles kubandakanya ukuqwalasela le miba ilandelayo:
I-Refractoriness: I-Graphite crucibles ifuna ukuchaswa okuphezulu ukumelana nobushushu obugqithisileyo.Ngoko ke, kubalulekile ukuvavanya ukuxhathisa umlilo we-graphite crucible material ukuqinisekisa ukusetyenziswa okukhuselekileyo.
Ukuzinza kweMichiza: Izibonda zegraphite zihlala zisetyenziswa kwiinkqubo zemichiza ezonakalisayo.Ke ngoko, ukuzinza kweekhemikhali zezinto ezikroliweyo zibalulekile ekunciphiseni ukubola.
Ukuqina kunye nokuqina: Ukuqina kunye nokuqina kwe-graphite crucible material kufuneka kuthathelwe ingqalelo ukukhusela ukuphuka kwe-brittle ngexesha lokusetyenziswa.
Ngokuthobela le migaqo yokukhetha izinto eziphathekayo ezingentla, sinokuqinisekisa ukusebenza kakuhle kwee-graphite crucibles.
Siyathemba ukuba ezi zikhokelo zokuhlola kunye nokukhethwa kwezinto eziphathekayo zibonelela ngengqiqo ebalulekileyo yokuvelisa kunye nokusetyenziswa kwee-graphite crucibles, ukuvumela ukusebenza okukhuselekileyo nokusebenzayo.
