Indlela yokuCoca iiCrucibles zeGraphite: Amanyathelo aphambili okwandisa uBomi beNkonzo

I-Graphite Cruciblezizixhobo ezisetyenziswa ngokubanzi kwi-metal smelting kunye nezicelo zobushushu obuphezulu.Zisetyenziselwa ukufudumeza isinyithi okanye ezinye izinto kubushushu obuphezulu bokunyibilika, ukuphosa, kunye nolunye ubushushu obuphezulu.Nangona kunjalo, ekuhambeni kwexesha, ukungcola okuhlukahlukeneyo kunye neentsalela ziqokelela phezu komgangatho we-crucible, echaphazela ukusebenza kwayo.Ngoko ke, ukuqonda indlela yokucoca ngokufanelekileyoiicrucibles zegraphitekubalulekile ekwandiseni ubomi babo benkonzo.Kule nqaku, siza kuzisa amanyathelo abalulekileyo okucoca ii-graphite crucibles.

 

Kutheni kufuneka sicoce i-graphite crucible?

Iintsimbi zegraphiteabasebenza kumaqondo obushushu aphezulu bathanda ukubhengeza nokufunxa ubumdaka obahlukeneyo, kubandakanywa iintsalela zentsimbi, iioksidi, kunye nezinye izinto ezingezizo ezentsimbi.Oku kungcola kunokubangela ukungcola ebusweni be-crucible, ukunciphisa ukuqhutyelwa kwayo kwe-thermal kunye ne-thermal conductivity.Ukongezelela, ukungcola okuqokelelweyo kunokubangela uxinzelelo lwe-thermal kwi-crucible, ekugqibeleni ikhokelela ekuqhekekeni okanye umonakalo.

Ngoko ke, ukucocwa rhoqo kwee-graphite crucibles kuyinyathelo eliphambili ekugcineni ukusebenza kwabo kunye nokwandisa ubomi babo benkonzo.

 

Amanyathelo aphambili okucoca iicrucibles zegraphite

Oku kulandelayo ngamanyathelo aphambili okucoca iicrucible zegraphite:

1. Amanyathelo okhuseleko:

Ngaphambi kokucoca i-graphite crucible, nceda uqinisekise ukuba amanyathelo afanelekileyo okhuseleko athathwa.Oku kuquka ukunxiba iiglavu ezikwaziyo ukumelana nobushushu kunye nezibuko zokukhusela ukwenzakala.

2. Ingqayi yokupholisa:

Ngaphambi kokucoca, qiniseka ukuba i-graphite crucible ipholile ngokupheleleyo.Ukucoca kwiqondo lokushisa eliphezulu kunokubangela ukutshitshiswa kweqondo lokushisa kunye nomonakalo kwi-crucible.

3. Susa iintsalela:

Sebenzisa i-metal scraper okanye i-pliers ukususa ngobumnene nayiphi na intsalela ebusweni be-crucible.Nceda usebenze ngononophelo ukunqanda ukukrwela i-crucible.

4. Ukucoca ngemichiza:

Kwezinye ezinzima ukususa ukungcola kunye neentsalela, ii-agent zokucoca iikhemikhali zingasetyenziswa.Khetha i-agent efanelekileyo yokucoca i-graphite crucibles, njenge-sodium hydroxide okanye isisombululo se-potassium hydroxide, kwaye ulandele imiyalelo yokusebenzisa i-arhente yokucoca.Ngokuqhelekileyo, i-arhente yokucoca iyachithwa emanzini afudumele kwaye i-crucible ifakwe kuyo ukuze ithobe kwaye isuse ukungcola.Emva kokugqitywa, hlambulula i-crucible ngokucokisekileyo ngamanzi acocekileyo ukukhusela ii-residues zeekhemikhali ukuba zihlale phezu komhlaba.

5. I-crucible yokomisa:

Emva kokucoca kunye nokuhlanjululwa, faka i-crucible kwi-oven ephantsi okanye umoya owomileyo ngokwemvelo ukuqinisekisa ukuba yomile ngokupheleleyo.Kuphephe ukusebenzisa ukufudumeza okubukhali okanye iinkqubo zokupholisa ukukhusela uxinzelelo lwe-thermal.

6. Jonga umphezulu we-crucible:

Emva kokucoca kunye nokumisa, jonga ngokucophelela umphezulu we-crucible ukuqinisekisa ukuba akukho ntsalela okanye umonakalo.Ukuba kuyimfuneko, ukucoca ngakumbi okanye ukulungiswa kunokwenziwa.

 

Ukhuseleko kunye neengcebiso

Xa ucoca ii-crucibles zegraphite, kukho ezinye izilumkiso ezibalulekileyo kunye neengcebiso:

Kuphephe ukusebenzisa iiarhente zokucoca ezineasidi njengoko zingonakalisa izinto zegraphite.

Musa ukusebenzisa iibrashi zentsimbi okanye iibrashi zocingo ukucoca i-crucible njengoko zinokukrwela umphezulu.

Xa usebenzisa ii-agent zokucoca iikhemikhali, nceda unxibe izixhobo zokukhusela kwaye uqinisekise ukuba umsebenzi wenziwa kwindawo engenamoya.

Ukucoca rhoqo i-crucible ukukhusela ukungcola kunye ne-residu ekuqokeleleni kwinqanaba elinzima ukuyiphatha.

Ngokweemfuno zenkqubo yokuvelisa, ukukhuselwa kwengubo okanye ukuphucula ukunyanzeliswa kwe-corrosion ye-graphite crucibles kunokukhethwa.

 

Cukuqukwa

Ukucoca i-graphite crucibles yinyathelo eliphambili ekugcineni ukusebenza kwabo kunye nokwandisa ubomi babo benkonzo.Ngokususa rhoqo ukungcola kunye neentsalela, kunye nokulandela amanyathelo afanelekileyo okucoca, kunokuqinisekiswa ukuba ii-graphite crucibles ziqhubeka nokusebenza kwizicelo eziphezulu zokushisa.Kwiinkalo zokunyibilika kwetsimbi kunye nokushisa okuphezulu, ukugcina ukucoceka kwee-crucibles kuyisitshixo ekuqinisekiseni imveliso ephezulu.
