- MELEMO EA KHABIDE EA SILICON E KHOKHANTSENG KA TS'OANTŠISO
Lihlahisoa tsa Silicon Carbide e Kopantsoeng le Reaction Bonded (RBSC, kapa SiSiC) li fana ka ho hanyetsa ho thatafala/ho abrasion ho feteletseng le botsitso bo ikhethang ba lik'hemik'hale libakeng tse mabifi. Silicon Carbide ke thepa ea maiketsetso e bonts'ang litšobotsi tse phahameng tsa ts'ebetso ho kenyeletsoa:
lHo hanyetsa lik'hemik'hale hantle haholo.
Matla a RBSC a batla a le 50% ho feta a di-carbide tse ngata tsa silicon tse tlamilweng ke nitride. RBSC ke ceramic e ntle ka ho fetisisa ya ho hanyetsa mafome le antioxidation. E ka bopjwa hore e be mofuta o fapaneng wa nozzle ya desulpurization (FGD).
lHo hanyetsa ho tsofala le tšusumetso e ntle haholo.
Ke sehlohlolo sa theknoloji e kholo ea letsopa e hanelang ho khohlela. RBSiC e na le bothata bo boholo bo batlang bo lekana le ba daemane. E etselitsoe ho sebelisoa lits'ebetsong tsa libopeho tse kholo moo lihlopha tsa silicon carbide tse hanyetsang li bonts'ang ho tsofala kapa tšenyo e bakoang ke tšusumetso ea likaroloana tse kholo. E hanela ho ts'oaroa ka kotloloho ha likaroloana tse bobebe hammoho le tšusumetso le ho thella ha lintho tse tiileng tse nang le slurry. E ka etsoa ka mefuta e fapaneng ea libopeho, ho kenyeletsoa libopeho tsa khoune le sleeve, hammoho le likarolo tse rarahaneng tse entsoeng ka boqapi tse etselitsoeng lisebelisoa tse amehang ts'ebetsong ea thepa e tala.
lHo hanyetsa mocheso hantle haholo.
Likarolo tsa carbide ea silicon tse kopantsoeng le karabelo li fana ka khanyetso e ikhethang ea ho thothomela ha mocheso empa ho fapana le li-ceramic tsa setso, li boetse li kopanya boima bo tlase le matla a phahameng a mechini.
lMatla a phahameng (a fumana matla mochesong).
Silicon carbide e tlamilweng ka karabelo e boloka boholo ba matla a yona a mechini mochesong o phahameng mme e bontsha maemo a tlase haholo a ho thekesela, e leng se etsang hore e be kgetho ya pele bakeng sa ditshebediso tse jarang mojaro pakeng tsa 1300ºC le 1650ºC (2400ºC ho isa ho 3000ºF).
