IGraphite yeCarbon Cruciblezizixhobo ezisetyenziswa ngokuqhelekileyo ekunyibilikeni kwesinyithi, izicelo zaselabhoratri, kunye nezinye iinkqubo zonyango lobushushu obuphezulu.Zinozinzo olubalaseleyo lobushushu obuphezulu kunye ne-thermal conductivity, ezenza zidume kakhulu kwezi zicelo.Eli nqaku liza kuhlolisisa indlela yokwenzaICarbon Graphite Crucible,ukusuka ekukhethweni kwemathiriyeli ekrwada ukuya kwinkqubo yokwenziwa kwemveliso yokugqibela.
Inyathelo 1: Khetha imathiriyeli efanelekileyo yegraphite
Isinyathelo sokuqala sokwenza i-graphite crucible kukukhetha izinto ezifanelekileyo zegraphite.Izibonda zegraphite zihlala zenziwe ngegraphite yendalo okanye eyenziweyo.Nazi ezinye izinto ekufuneka ziqwalaselwe xa ukhetha imathiriyeli yegraphite:
1. Ubunyulu:
Ukucoceka kwegraphite kubalulekile ekusebenzeni kwe-crucible.Iicrucibles zegraphite ezicocekileyo zinokusebenza ngokuzinzileyo kumaqondo obushushu aphezulu kwaye azichatshazelwa lula kukusabela kweekhemikhali.Ke ngoko, ukwenza iicrucibles zegraphite ezikumgangatho ophezulu ngokuqhelekileyo kufuna ukusetyenziswa kwezinto ezisulungekileyo zegraphite.
2. Ulwakhiwo:
Ubume beGraphite Lined Crucible nayo yinto ephambili.Igraphite ecolekileyo idla ngokusetyenziselwa ukwenziwa ngaphakathi kweecrucibles, ngelixa igraphite ecolekileyo isetyenziselwa ukwenza iqokobhe langaphandle.Esi sakhiwo sinokubonelela ngokumelana nokushisa okufunekayo kunye ne-thermal conductivity ye-crucible.
3. I-Thermal conductivity:
I-graphite yinto egqwesileyo ye-thermal conductive, enye yezizathu zokuba i-graphite crucibles isetyenziswe ngokubanzi kwizicelo eziphezulu zokushisa.Ukukhetha izinto zegraphite ezine-conductivity ephezulu ye-thermal kunokuphucula izinga lokushisa kunye nokupholisa kwe-crucible.
4. Ukumelana nokuMhlwa:
Ngokuxhomekeke kwiipropati zezinto ezicutshungulwayo, ngamanye amaxesha kuyimfuneko ukukhetha izinto zegraphite ezinokumelana nokubola.Ngokomzekelo, ii-crucibles eziphethe izinto ezine-acidic okanye i-alkaline zifuna i-graphite enokumelana nokubola.
Inyathelo lesi-2: Lungiselela imathiriyeli yokuqala yegraphite
Emva kokuba kukhethwe imathiriyeli efanelekileyo yegraphite, inyathelo elilandelayo kukulungisa imathiriyeli yantlandlolo yegraphite ibe yimo yecrucible .Le nkqubo ibandakanya la manyathelo alandelayo:
1. Ukutyumza:
Izinto zokuqala zegraphite zidla ngokuba zikhulu kwaye zifuna ukutyunyuzwa zibe ngamasuntswana amancinci ukuze kuqhutyekwe phambili.Oku kunokufezekiswa ngokutyunyuzwa ngoomatshini okanye ngeendlela zeekhemikhali.
2. Ukuxuba kunye nokubopha:
Iinqununu ze-graphite ngokuqhelekileyo kufuneka zixutywe kunye nee-agent ezibophezelayo ukuze zenze imilo yokuqala ye-crucible.Izibophelelo zinokuba yi-resins, i-adhesives, okanye ezinye izinto ezisetyenziselwa ukudibanisa amaqhekeza e-graphite ukugcina isakhiwo esomeleleyo kumanyathelo alandelayo.
3. Uxinzelelo:
I-graphite edibeneyo kunye ne-binder ngokuqhelekileyo kufuneka icinezelwe ibe yimo ye-crucible phantsi kweqondo lokushisa eliphezulu kunye noxinzelelo.Eli nyathelo lidla ngokugqitywa ngokusebenzisa isikhunta esikhethekileyo se-crucible kunye nomshicileli.
4. Ukomisa:
I-crucible crucible ngokuqhelekileyo kufuneka yomiswe ukususa umswakama kunye nezinye i-solvents kwi-agent ebophelelayo.Eli nyathelo linokuthi liqhutywe kwiqondo lokushisa elincinci ukukhusela i-deformation okanye ukuqhekeka kwe-crucible.
Inyathelo 3: Sintering kunye nokusebenza
Emva kokuba i-crucible yasekuqaleni ilungisiwe, i-sintering kunye neenkqubo zonyango kufuneka zenziwe ukuze kuqinisekiswe ukuba i-crucible inomsebenzi ofunekayo.Le nkqubo ibandakanya la manyathelo alandelayo:
1. Sintering:
I-Crucible yasekuqaleni ngokuqhelekileyo kufuneka ifakwe kwi-sintered kwiqondo lokushisa eliphezulu ukwenza iinqununu ze-graphite zibophe ngakumbi kwaye ziphucule ubuninzi kunye namandla e-crucible.Eli nyathelo lidla ngokuqhutywa phantsi kwenitrogen okanye umoya ongasebenziyo ukukhusela i-oxidation.
2. Unyango lomphezulu:
Umgangatho wangaphakathi nangaphandle we-crucibles ngokuqhelekileyo ufuna unyango olukhethekileyo lokuphucula ukusebenza kwabo.Umphezulu wangaphakathi unokufuna ukugquma okanye ukugquma ukwandisa ukuxhathisa okanye ukuphucula ukuqhutyelwa kobushushu.Umphezulu wangaphandle unokufuna ukucolisa okanye ukupholisa ukuze ufumane indawo egudileyo.
3. Ukuhlolwa nokulawula umgangatho:
Ukuhlolwa okungqongqo kunye nokulawulwa komgangatho kufuneka kwenziwe ngexesha lenkqubo yokuvelisa ukuqinisekisa ukuba i-crucible ihlangabezana neemfuno ezicacileyo.Oku kubandakanya ukujonga ubungakanani, ubuninzi, ukuhanjiswa kwe-thermal, kunye nokunganyangeki kwe-corrosion ye-crucible.
Inyathelo 4: Ukusetyenzwa kokugqibela kunye neemveliso ezigqityiweyo
Ekugqibeleni, i-crucible elungiselelwe ngokusebenzisa la manyathelo angentla inokufakwa phantsi kokulungiswa kokugqibela ukufumana imveliso egqityiweyo.Oku kubandakanya ukucheba imiphetho ye-crucible, ukuqinisekisa imilinganiselo echanekileyo, kunye nokujonga umgangatho wokugqibela.Emva kokuba i-crucible idlula ulawulo lomgangatho, inokupakishwa kwaye isasazwe kubathengi.
Ngamafutshane, ukwenza i-graphite crucibles yinkqubo enzima efuna ubugcisa obuchanekileyo kunye nezixhobo eziphezulu ze-graphite.Ngokukhetha izinto ezifanelekileyo, ukulungiselela izinto eziluhlaza, ukuhlamba kunye nokucutshungulwa, kunye nokuphumeza ukulawulwa komgangatho ongqongqo, i-graphite crucibles ephezulu inokuveliswa kwizicelo ezahlukeneyo zokushisa okuphezulu.Ukwenziwa kweecrucibles zegraphite yinxalenye ebalulekileyo yecandelo lobunjineli begraphite, ukubonelela ngesixhobo esiyimfuneko kwizicelo ezahlukeneyo zeshishini nezesayensi.
