Ama-Crucibles ayizinto ezibalulekile ze-apparatus yamakhemikhali futhi zisebenza njengeziqukathi zokuncibilika nokucwilisa uketshezi lwensimbi, kanye nokushisa kanye nokusabela okuxubile okuqinile. Bakha isisekelo sokuqinisekisa ukusabela okubushelelezi kwamakhemikhali.
Ama-Crucibles angahlukaniswa izigaba ezintathu eziphambili:ama-graphite ama-brucIbles, Clay Brucibles, kanye ne-Metal Crucibles.
Ama-graphite ama-brucibles akhiqizwa yi-graphite yemvelo yemvelo, egcina izakhiwo ezahlukahlukene zomzimba nezamakhemikhali ze-graphite yemvelo. Banokuvuka okuhle okushisayo kanye nokumelana okushisa okuphezulu. Ngesikhathi sokusetshenziswa okushisa kakhulu, bakhombisa ama-coefficients aphansi kakhulu, abenze bamelane nokushisa okusheshayo nokupholisa. Ama-graphite ama-brucIbles anokumelana okuqinile kokugqwala kwezixazululo ze-acidic ne-alkali futhi akhombisa ukuqina kwamakhemikhali okuhle kakhulu.
Ngenxa yalezi zimpawu eziphakeme, ama-graphite ama-trapIble asetshenziswa kabanzi ezimbonini ezinjenge-metallurgy, ukuphonsa, imishini, kanye nobunjiniyela bamakhemikhali. Bathola uhlelo lokusebenza olubanzi ekubhemeni kwamathuluzi ethuluzi le-alloy kanye nokuncibilika kwezinsimbi ezingezona ze-ferrous kanye nama-alloys abo, kunikeza izinzuzo eziphawuleka zezobuchwepheshe nezomnotho.
I-Silicon Carbide Carbide:
I-Silicon Carbide Carbide iziqukathi ze-ceramic ezimise okwenziwe ngokobumba. Lapho ama-solids edinga ukufudunyezwa emazingeni okushisa aphezulu, ama-ethruthi ayadingeka ngoba angamelana namazinga okushisa aphezulu ngokuqhathaniswa ne-glassware. Ama-Crucibles ajwayele ukugcwala amandla ngesikhathi sokusetshenziswa ukuvikela impahla efudumele ekuchithekeni ngaphezulu, ukuvumela umoya ukuba ufake ngokukhululekile futhi uhambise ukusabela kwe-oxidation ngokukhululekile. Ngenxa yesisekelo sabo esincane, ama-errucles ngokuvamile afakwa kunxantathu lobumba lokushisa okuqondile. Zingabekwa ziqonde noma ziqonde ku-angle ku-iron tripod, ngokuya ngezidingo zokuhlola. Ngemuva kokushisa, ama-eartibles akufanele abekwe ngokushesha endaweni yensimbi ebandayo ukugwema ukupholisa okusheshayo nokuqhekeka okungaba khona. Ngokufanayo, akufanele zibekwe ngqo endaweni engaphezulu kokhuni ukuvikela ukucekelwa phansi noma izingozi zomlilo. Indlela efanelekile ukuvumela ama-turcibles ukuthi aphole ngokwemvelo ku-iron tripod noma awabeke ku-asbestos net yokupholisa kancane kancane. Izingcingo ezisebenzayo kufanele zisetshenziselwe ukuphatha.
I-Platinamu Eartibles:
Ama-Platinamu ama-Crucibles, enziwe nge-platinamu yensimbi, asebenze njengezingxenye ezisele zabahlaziyi bokuhlukahluka okuhlukile futhi asetshenziselwa ukufudumeza izinto ezingezona zensimbi, njengokukhiqizwa kwefayibha yengilazi kanye nomdwebo wengilazi.
Akufanele bahlangane ne:
Amakhompiyutha aqinile afana ne-K2O, NA3O, KNO3, Nano3, KCN, NACN, NACN, NACN), BA (OH) 2, LIOH, njll.
I-Aqua Regia, izixazululo zeHalogen, noma izixazululo ezikwazi ukukhiqiza ama-halogens.
Amakhompiyutha wezinsimbi ezivuselelwe kalula kanye nezinsimbi ngokwazo.
I-Carbon - equkethe izilindi, phosphorus, i-arsenic, isibabule, kanye namakhompiyutha awo.
I-Nickel Crucibles:
Iphuzu lokuncibilika le-nickel lingama-degrees angama-1455 ama-degrees, kanti izinga lokushisa lesampula elisebangeni le-nickel akufanele lidlule ku-700 degrees Celsius ukuvikela i-oxidation emazingeni okushisa aphezulu.
Ama-nickel ama-rucibles amelana kakhulu nezinto ze-alkaline kanye nokugqwala, abenze balungele ukuncibilika kwensimbi, i-slag, ubumba, izinto ezibonakalayo, nokuningi. I-Nickel Crucibles iyahambisana ne-Alkaline Flues enjengeNaoh, NA2O2, NACO3, nalabo abane-KHO3, kepha akufanele basetshenziswe nge-KHSO4, noma i-K2S2O7, noma i-NA2S2O7 ne-Sulfide Flues ngesibabule. Usawoti oncibilikayo we-aluminium, i-zinc, ukuhola, i-tin, futhi i-mercury ingakhipha ama-nickel abhubhise. Ama-Nickel ama-Crucibles akufanele asetshenziselwe ama-precipitate avuthayo, futhi i-borax akufanele incibilikiswe kuzo.
Ama-nickel ama-rucibles avame ukuqukethe amanani alandelwayo we-chromium, ngakho-ke kufanele kusetshenziswe ukuqapha lapho, kuphazamiseka.
