Ha tailings slurry morafo e ama phaephe ka lebelo le phahameng, ha slag phahameng-thempereichara ka workshop metallurgical tsoela pele ho hlatsoa lerako le ka hare, 'me ha tharollo e matla ea asiti ka workshop ea lik'hemik'hale corrodes lerako la phala letsatsi le letsatsi - liphaephe tse tloaelehileng tsa tšepe hangata li lutla ka mor'a likhoeli tse seng kae feela. Empa ho na le mofuta oa liphaephe tse ka pholohang “pelekatoring ea indasteri” joalo ntle le kotsi, ’me kephaephe e manganga e entsoeng ka silicon carbidejoalo ka thepa ea mantlha. Ke bohlale ba mofuta ofe boo karolo ee e bonahalang e tloaelehile indastering e pata?
Khoutu ea thepa e manganga ho feta tšepe
Pale ea silicon carbide e qalile ho elella bofelong ba lekholo la bo19 la lilemo ha bo-rasaense ba sibolla motsoako ona o thata ka phoso ha ba ntse ba leka ho etsa daemane ea maiketsetso. Ke ntho e sa tloaelehang haholo ka tlhaho 'me e tsejoa e le "Moissanite", ha silicon carbide e sebelisoang indastering kajeno e batla e le sehlahisoa sa maiketsetso a maiketsetso.
Lekunutu la ho etsa liphaephe tsa silicon carbide joalo "tse hananang le tlhahiso" le ka har'a microstructure ea tsona e ikhethang. Tlas'a microscope ea elektronike, likristale tsa silicon carbide li bonts'a sebopeho sa tetrahedral se ts'oanang le daemane, 'me athomo e' ngoe le e 'ngoe ea silicon e pota-potiloe ka thata ke liathomo tse' nè tsa carbon, ho etsa marang-rang a ke keng a robeha a covalent. Sebopeho sena se fana ka boima ba bobeli ho daemane, ka boima ba Mohs ba 9.5, ho bolelang hore esita le khoholeho e sa khaotseng ea lehlabathe la quartz (Mohs hardness of 7) ho thata ho tlohela mesaletsa.
Ntho e sa tloaelehang le ho feta ke hore silicon carbide ha e thata feela, empa hape e hanyetsana haholo le mocheso o phahameng. Ka mocheso o phahameng oa 1400 ℃, e ntse e khona ho boloka thepa e tsitsitseng ea mochine, e leng se etsang hore e sebetse hantle maemong a phahameng a mocheso a kang ho tsamaisoa ha phofo ea mashala ka libopi tsa tšepe tse phatlohang ka tšepe ea tšepe le ho tsoa ha boiler slag ho hlahisa matla a mocheso. Ka nako e ts'oanang, "e itšireletsa" ho khoholeho ea boholo ba li-acids le alkalis, 'me ho hanyetsa ha kutu ho bohlokoa ka ho khetheha liphaepheng tse matla tsa phetisetso ea asiti indastering ea lik'hemik'hale.
Filosofi ea moralo ho eketsa bophelo ba liphaephe ka makhetlo a leshome
Ho thatafala ha bonolo ha hoa lekana ho sebetsana le maemo a rarahaneng a indasteri. Liphaephe tsa sejoale-joale tsa silicon carbide tse hananang le ho roala li nka meaho e kopaneng e bohlale: hangata lesela le kantle ke tšepe e tloaelehileng ea khabone e fanang ka ts'ehetso ea sebopeho, lesela le kahare ke lesela la silicon carbide ceramic, 'me liphaephe tse ling li boetse li phuthela fiberglass ka ntle ho matlafatsa matla ka kakaretso. Moralo ona ha o phahamise feela molemo oa ho hanyetsa oa silicon carbide, empa o boetse o lefella brittleness ea lisebelisoa tsa ceramic.
Baenjiniere ba tla boela ba etse "moralo o fapaneng" o ipapisitse le boemo ba likarolo tse fapaneng tsa lipeipi. Ka mohlala, haeba arc e ka ntle ea setsoe e apere haholo, ho tla sebelisoa lesela le teteaneng la silicon carbide; Haeba moaparo oa ka hare oa arc o batla o le bobebe, o lokela ho fokotsoa ka nepo ho netefatsa hore o tšoarella le ho qoba litšila tsa lintho tse bonahalang.
Ts'ebeliso ea theknoloji ea reaction sintering e etsa hore liphaephe tsa silicon carbide li be tse phethahetseng haholoanyane. Ka ho laola hantle mocheso le karo-karolelano ea lihlahisoa tse tala, thepa e ka finyella boemo bo teteaneng ka hoo e batlang e le zero porosity, ha e ntse e hlahisa likaroloana tsa graphite ho etsa lera la ho itlotsa. Ha mokelikeli ona o ntša phaephe, lesela la graphite le etsa filimi e sireletsang, e leng ho fokotsang khohlano, joalo ka ho beha “sehlomo sa ho tlotsa” phaepeng.
Ho tloha indastering ea mali ho ea ho bokamoso bo botala
Liindastering tse boima tse kang matla a mocheso, merafo, metallurgy le boenjiniere ba lik'hemik'hale, tsamaiso ea liphaephe e tšoana le "mali a indasteri", 'me ho tšepahala ha bona ho amana ka ho toba le polokeho ea tlhahiso le katleho. Hangata liphaephe tsa tšepe tse tloaelehileng li hloka ho nkeloa sebaka nakong ea likhoeli tse 3 libakeng tse matla tsa ho apara, ha bophelo ba tšebeletso ea liphaephe tse sa tsitsang tsa silicon carbide li ka atolosoa ka makhetlo a fetang 10, ho fokotsa haholo ho fokotsa nako ea ho fokotsa nako.
Tšobotsi ena e tšoarellang nako e telele e boetse e tlisa melemo ea bohlokoa ea tikoloho. Ho fokotsa tšebeliso ea liphaephe ho bolela ho fokotsa tšebeliso ea tšepe, 'me mekhoa e tsoetseng pele ea ho qhibilihisa e sebelisoang ts'ebetsong ea tlhahiso (e kang mokhoa oa ESK) e ka khutlisa litšila tsa khase bakeng sa ho fehla matla, ho eketsa tšebeliso ea matla ka 20%. Libakeng tse ntseng li hlaha tse kang tlhahiso ea betri ea lithium le lisebelisoa tsa ts'ireletso ea tikoloho, ho bola le ho roala ha liphaephe tsa silicon carbide le tsona li bapala karolo ea bohlokoa.
Ha re bua ka tsoelo-pele ea indasteri, hangata re shebana le lihlahisoa tse benyang tsa theknoloji e phahameng, empa re hlokomoloha habonolo "bahale ba ka morao" joalo ka liphaephe tse sa sebetseng tsa silicon carbide. Hantle-ntle ke mokhoa ona o mocha o eketsang thepa ea thepa ea motheo e tšehetsang ts'ebetso e sebetsang ea indasteri ea morao-rao. Ho tloha merafong ho ea lifekthering, ho tloha liboping tsa mocheso o phahameng ho ea ho lithupelo tsa lik'hemik'hale, 'lithebe tsena tse kholo ka ho fetisisa' tse khutsitseng li kenya letsoho polokehong le ts'ebetsong ea tlhahiso ea indasteri ka tsela ea tsona.
