Lapho uqhuba izivivinyo zamakhemikhali okushisa aphezulu noma izicelo zezimboni, ukukhetha izinto ezisebenzayo kudlala indima ebalulekile ekuqinisekiseni impumelelo nokuphepha kwenqubo. Izinhlobo ezimbili ezisetshenziswa kaningi ze-crucibles zikhonaubumba lwe-graphite braphitena-I-Graphite Silicon Carbide Carbide Carbibles. Ukuqonda ukwakheka kwalo ngokwezinto ezibonakalayo, izinga lokushisa le-refractory, ukuwohloka kwamakhemikhali, nokuvuselelwa okushisayo kubalulekile ekwenzeni isinqumo esinolwazi lapho ukhetha i-escuciloretory efanelekile noma izidingo zezimboni.
Izithako Ezibonakalayo:
I-graphite ye-Clay iBrassHible ihlanganiswa kakhulu i-graphite, ubumba kanye nenani elithile lokugcotshwa, futhi yaziwa ngamandla alo wamakhemikhali. Ngakolunye uhlangothi, i-Graphicon Carbide enokwenziwa kwe-silicon yenziwe nge-silicon carbide powder kanye neminye imihlaba engavamile yoxides, futhi inezimpawu zokumelana okuphezulu okuphezulu, ukumelana okuhle kakhulu okushisayo, kanye nokuqina kwamakhemikhali aphezulu.
Ukushisa komlilo lokushisa komlilo:
Ukushisa okuzenzakalelayo kobumba lwe-graphite braphibles ngokuvamile kufinyelela cishe ngo-1200 ° C, ngenkathi ama-graphiton Carbide Carbide Carbide angamelana namazinga okushisa angaphezu kuka-1500 ° C. Lokhu kwenza ama-filicon carbide ama-aillicon ama-erucible alungele izinhlelo zokusebenza ezidinga amazinga okushisa aphezulu ezihlolweni zamakhemikhali nezinqubo zezimboni.
Ngokwekhemikhali indert:
Zombili lezi zinhlobo zama-tucibles zibonisa izinga lokungena kwamakhemikhali, okusele ezitebeleni eziningi ezi-acid, i-alkali, kanye nezixazululo kasawoti futhi zimelana nokugqwala. Kodwa-ke, ingxenye yobumba ngobumba ama-graphite ama-graphite yenza kube lula ukudonsa umkhondo izinto nokungcola uma kuqhathaniswa ne-graphito Carbide Carbide.
Ukuvuselelwa okushisayo:
I-Graphite inokuqhutshwa okuphezulu okushisayo futhi kungaqeda ukushisa ngokushesha. Kodwa-ke, ngenxa yokwakheka okusemthethweni kwe-graphible yobumba ebekiwe, amabala amnyama athambekele ekubonakaleni ebusweni bawo futhi adinga ukuhlanzwa kaningi. Ngokuphambene, ama-graphicon carbide ama-rucibles anokuphakelayo okuphansi okushisayo futhi ngeke ashiye amabala ebusweni. Ngaphezu kwalokho, ubulukhuni babo obuphakeme buvimbela ukugqoka nokukhubazeka.
Khetha okunobunzima:
Lapho ukhetha ilabhorethri enamakhemikhali ebekiwe, kufanele acatshangwe. I-Clay graphite crucibles ilungele izivivinyo ze-General Chemistry, ngenkathi ama-graphiton Carbide Carbide ama-Carbide alungele izivivinyo ezidinga amazinga okushisa aphezulu kanye nezimo ezifunwa kakhulu. Kubalulekile ukulandela ngokuqinile imiyalo yokusebenzisa ukugwema ukwehluleka kokuhlola ngenxa yokusebenza okungafanele.
Ngamafuphi, ukuqonda umehluko phakathi kwe-crsite ye-graphicon Carbide ye-Graphicon Carbide kubalulekile ekukhetheni okubaleka okufanele kakhulu kwelebhu noma yezimboni. Ngokucabanga ngezinto ezifana nokushisa okuzenzakalelayo, ukuqina kwamakhemikhali kanye nokuvuselelwa kwamakhemikhali, abacwaningi kanye nabacwaningi bezimboni bangenza izinqumo ezinolwazi zokuqinisekisa impumelelo nokuphepha kwezivivinyo nezinqubo.
