Iindidi ezahlukeneyo zokubethelela zinezibonelelo ezahlukeneyo

Iinqaba zenziwe izinto ezibalulekileyo zeekhemikhali kwaye zisebenze njengezikhongozeli zokunyibilika kunye nolwelo oluhlaziyiweyo, kunye nokufudumeza kunye nokuphendula umxube oqinileyo. Benza isiseko sokuqinisekisa ukuphendula okuhle sekhemikhali.

I-Crumbeds inokwahlulwa yangamacandelo amathathu aphambili:I-greyitite crucabs, I-Clay Crubibles, kwaye i-shor yentsimbi.

I-greyitite crucabs:

Igrafu ye-greyitite yenziwa ngokuyintloko kwi-crystalline ye-grastaline, igcina iimpawu ezahlukeneyo zomzimba kunye neekhemikhali zegrafu yendalo. Baphethe ukuqhubela phambili kobushushu kunye nokuxhathisa kobushushu obuphezulu. Ngexesha lokusetyenziswa kobushushu obuphakathi, babonisa i-coefficial yokwandiswa komhlaba, ukubangela ukuba bazixhathise ukufudumeza ngokukhawuleza nokupholisa. Igrafu yefomathi ineempawu eziqinisekileyo zokunganyangekiyo kwi-acidic kunye ne-alkaline solution kwaye bonisa uzinzo olufanelekileyo.

Ngenxa yezi mpawu zibalaseleyo, iigrafu ezigcweleyo zisetyenziswa ngokubanzi kumashishini anjengesithili, ekuphoseni, oomatshini, kunye nobunjineli bemichiza. Bafumana isicelo esibanzi kwi-spelting yesixhobo se-Alloty steels kunye nokunyibilika kwezinyithi ezingezo ntliziyo kunye nezibonelelo zazo zetekhnoloji, zinika izibonelelo ezizayo zetekhnoloji.

I-Silicon Carbide Crubibles:

I-Silicon Carbide Crubibles zizikhombisi ze-ceramic. Xa i-slidics kufuneka ifuduselwe kubushushu obuphezulu, iimbethe ezinqabileyo ziyimfuneko kuba zinokumelana nobushushu obuphakathi xa kuthelekiswa neglasi. Ukubethelelwa kukubethelwa ngokungagungqiyo xa kusenziwa izinto ezifudumeleyo ukuba zichithe ngaphezulu, ukuvumela umoya ukuba angenise kwaye ukuqhubela phambili ukuphendula ngokukhululekileyo. Ngenxa yesiseko sabo esincinci, iimbethe ezinqamlezileyo zihlala zibekwe kwinxantathu yedongwe yokufudumeza ngokuthe ngqo. Banokubekwa ngqo okanye kwi-engile kwi-iron tripod, kuxhomekeke kwiimfuno zovavanyo. Emva kokufudumeza, iinqaba akufuneki zibekwe ngoko nangoko kumhlaba obandayo wesinyithi wokuphepha ukuphola ngokukhawuleza okukhoyo nokuqhawuka. Ngokufanayo, akufuneki zibekwe ngqo kumphezulu wamaplanga ukuthintela ukuqaqamba okanye ubushushu bomlilo. Inkqubo echanekileyo kukuvumela i-therheds ukuba ipholile ngokwemvelo kwi-iron tripod okanye ibeka kwindawo yokuphola kancinci. Izikhonkwane ezihleliweyo kufuneka zisetyenziselwe ukuphatha.

I-Platinam Churcabs:

IPlatinam Crubibles, eyenziwe ngeplatinam yensimbi, isebenza njengezixhobo zokuhlalutywa kwe-thermal eyahlukileyo kwaye isetyenziselwa ukufudumeza izinto ezingafunekiyo, ezinje ngomzobo we-fiber yeglasi kunye nomzobo we-fiber yeglasi kunye nomzobo we-fiber yeglasi.

Akufanelanga banxibelelane ne:

Imifanekiso eqingqiweyo efana ne-k2o, na2 ,, Kno3, Nano, Na2, Ba (Oh) 2, I-LIOH, njl.

I-Aqua Graia, izisombululo ze-halogn, okanye izisombululo ezinamandla okuvelisa ii-halogens.

Iikhomputha zezinyithi ezicotha ngokulula kunye neentsimbi ngokwazo.

I-carbon-enezityalo, i-phosphorus, i-phosfenic, i-sulfure, kunye nemichiza yazo.

I-Nickel Crubles:

Indawo yokunyibilika yeNickel yi-1455 degrees celsius, kwaye iqondo lobushushu lesampulu kwi-nickel mitrucked akufuneki lidlule kwi-degrees kwi-oxidation kwiqondo lobushushu ephezulu.

I-Nickel Crubibles ixhathisa kakhulu kwizinto ze-alkaline kunye nokuzibophelela, zibenza balungele ukunyibilika inyibiliki, izixhobo ze-SLAG, kunye nezinye izinto eziphikisayo, nangaphezulu. I-Nickel Crubibles iyahambelana ne-alkaline fluxes ezinjengoNah, Naco2, i-Nahso4, kodwa akufuneki zisetyenziswe kwi-khso4, kodwa akufuneki zisetyenziswe nge-khsos2s2o7, okanye i-na2s2s Inyibiliki ye-aluminium, i-zinc, ikhokeli, i-tin, kunye ne-mercury inokunikezela nge-nickel torubles brittle. I-Nickel Crubles akufuneki isetyenziselwe ukutsha okutsha, kunye ne-borax akufuneki inyibilike kuzo.

I-Nickel Crubles zihlala ziqukethe izixa ze-chromium, ngenxa yoko kufuneka zisetyenziswe xa, iseshoni iphazamisekile.
