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 aphambili 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.
