- MELEMO EA HO SEBELISA SILICON CARBIDE
Lihlahisoa tsa Reaction Bonded Silicon Carbide (RBSC, kapa SiSiC) li fana ka ho thatafala ho fetelletseng / abrasion ho hanyetsa 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 kenyelletsa:
lE babatsehang khanyetso ea lik'hemik'hale.
Matla a RBSC a batla a le 50% ho feta a li-silicon carbides tse ngata tsa nitride. RBSC ke khanyetso e ntle ea kutu le antioxidation ceramic .. E ka etsoa ka mefuta e fapaneng ea desulpurization nozzle (FGD) .
lHo apara hantle le ho hanyetsa tšusumetso.
Ke tlhōrō ea theknoloji e kholo ea abrasion resistant ceramic. RBSiC e na le boima bo phahameng bo atamelang ba daemane. E etselitsoe ho sebelisoa lits'ebetsong tsa libopeho tse kholo moo limaraka tsa silicon carbide li bonts'ang ho senyeha kapa ho senyeha ka lebaka la tšusumetso ea likaroloana tse kholo. E hanana le ho kengoa ka ho otloloha ha likaroloana tsa leseli hammoho le tšusumetso le ho khojoa ha lintho tse thata tse nang le li-slurries. E ka etsoa ka mefuta e fapaneng ea libopeho, ho kenyeletsoa libopeho tsa cone le sleeve, hammoho le likotoana tse rarahaneng tsa boenjiniere tse etselitsoeng lisebelisoa tse amehang ts'ebetsong ea lisebelisoa tse tala.
lE babatsehang ho hanyetsa mocheso oa mocheso.
Likarolo tse kopantsoeng tsa silicon carbide li fana ka ts'ebetso e ikhethang ea mocheso oa mocheso empa ho fapana le lirafshoa tsa setso, li boetse li kopanya letsoalo le tlase le matla a phahameng a mochini.
lMatla a phahameng (ho fumana matla ka mocheso).
Reaction bonded Silicon carbide e boloka boholo ba matla a eona a mochini mochesong o phahameng mme e bonts'a maemo a tlase haholo a ho thella, e e etsa khetho ea pele bakeng sa lits'ebetso tse jarang meroalo ho tloha ho 1300ºC ho isa ho 1650ºC (2400ºC ho isa ho 3000ºF).
