Ezimbonini ezahlukahlukene, kukhona umbono ongelona iqiniso maqondana nokusetshenziswa kweI-graphite ecashile. Abantu abaningi bakholelwa ngephutha ukuthi le mikhiqizo inokubaluleka okuncane emakethe, ibacabanga ukuthi ingabalulekile. Kodwa-ke, lo mbono wawungeke ube kude ngeqiniso. Ngenkathi ama-graphite ama-bructite angahle abonakale enokwakhiwa okulula - yakhelwe ukuqukatha amatshe ahlukahlukene - Ukungabikho kwawo kungaholela ezindabeni ezibalulekile kuyo yomibili imikhakha ye-metallurgical kanye namakhemikhali. Masinikeze izinzuzo ze-Graphite Crucibles futhi sihlole izinhlelo zazo ezahlukahlukene.
1. Ukuguquguquka nokuqina
Enye yezinzuzo ezivelele ze-graphite ama-brucIbles zilele ekuguquguqukeni kwazo ezihlukahlukene. Lezi zinzulu ngokuyinhloko zakhiwa i-graphite ne-quartz, ezihlanganiswa namakhemikhali ahlukahlukene amakhemikhali bese zibhekwa ngokudubula okushisa okuphezulu ngokukhiqizwa kwazo. Lokhu kuhlanganiswa okuyingqayizivele kunika amandla ama-graphite ama-rucibles akwazi ukumelana kahle ne-acidic, alkali, kanye noketshezi oluzololonda, ukubanikeza okubaluleke kakhulu embonini yamakhemikhali. Ukuhlolwa okubanzi kososayensi kukhombisile ukuthi ngisho ne-Aqua Regia - ingxube elonakalisayo ye-acid - ingatholakala ngokuphephile ngaphakathi kwe-graphite tucibles.
Ngaphezu kwalokho, ama-graphite amabhulukwe abonisa ukumelana nokushisa okumangalisayo, okukwazi ukubekezelela amazinga okushisa adlula ama-degree angama-5000 Celsius ngaphandle kokuwohloka okukhulu. Lokhu kubenza balungele ukuqukethe insimbi encibilikisiwe, i-aluminium nezinye izinsimbi ngisho nasesimweni sabo se-liquid, baphinde baphinde basebenzise umsebenzi wabo kuyo yonke imboni ehlukahlukene.
2. Ikhwalithi engaguquki
Izinga le-graphite rucibles kungenye inzuzo ebalulekile. Lezi zinwele zenzelwe ukubekezelela ingcindezi yangaphandle yangaphandle, kubenza bamelana kakhulu nezinsongo ngaphandle kokuthi zibe ngaphansi kwamandla abo. Inqubo yokukhiqiza ye-graphite ngayinye inamathela ezindinganisweni eziqinile, iqinisekisa ukucaca esinyathelweni ngasinye. Kuphela ngale ndlela yokucophelela ingabhekwa njengomkhiqizo wokugcina ofanelekile ngenhloso.
I-graphite ngayinye ebekwe ekuhlolweni kwekhwalithi eqinile ngaphambi kokuba itholakale kumakhasimende. Imizimba yokulawula yenza amasheke angahleliwe kule mikhiqizo, futhi noma yiziphi izehlakalo zokungalandeli kungaholela ekukhiqizweni kwamahlaya kanye nezinhlawulo ezinkulu, noma ukuvalwa kwesikhungo sokwenziwa. Izindlela eziqinile zisendaweni ngenxa yokulimaza okuqukethwe okuvuthiwe kungadala impilo yabantu. Ukuvimbela ukuvuza okunjalo kudinga ukubhekana nalolu daba empandeni yalo, kuqale ngokukhiqizwa kwalezi zinwele.
