Seqhoa se thata ka ho fetesisa sa Silicon Carbide Grit
Tlhaloso ea Sehlahisoa
Junda Silicon Carbide Grit ke mecha ea phatlalatso e matla ka ho fetisisa e fumanehang. Sehlahisoa sena sa boleng bo holimo se entsoe ka sebopeho sa lijo-thollo tse thibaneng. Mecha ena ea litaba e tla senyeha ka ho tsoelang pele ho fella ka mahlakoreng a bohale, a sehang. Ho thatafala ha Silicon Carbide Grit ho lumella nako e khuts'oane ea ho phatloha ho amanang le mecha ea litaba e bonolo.
Ka lebaka la thepa ea eona e tsitsitseng ea lik'hemik'hale, mocheso o phahameng oa mocheso, tekanyo e tlaase ea ho atolosa mocheso, le ho hanyetsa ho apara hantle, silicon carbide e na le lisebelisoa tse ling tse ngata ntle le ho sebelisoa e le li-abrasives. Ka mohlala, phofo ea silicon carbide e sebelisoa ho impeller kapa cylinder ea turbine ea metsi ka mokhoa o khethehileng. Lerako le ka hare le ka ntlafatsa ho hanyetsa ha lona le ho lelefatsa bophelo ba eona ba tšebeletso ka makhetlo a 1 ho isa ho a 2; thepa ea boleng bo phahameng ea refractory e entsoeng ka eona e na le ho hanyetsa mocheso oa mocheso, boholo bo nyane, boima bo bobebe, matla a phahameng le phello e ntle ea ho boloka matla. Silicon carbide ea boemo bo tlase (e nang le hoo e ka bang 85% ea SiC) ke deoxidizer e ntle haholo. E ka potlakisa lebelo la ho etsa tšepe, 'me ea bebofatsa taolo ea sebopeho sa lik'hemik'hale le ho ntlafatsa boleng ba tšepe. Ntle le moo, silicon carbide e boetse e sebelisoa haholo ho etsa lithupa tsa silicon carbide bakeng sa likarolo tsa ho futhumatsa tsa motlakase.
Silicon carbide e na le boima bo phahameng haholo, e nang le boima ba Mohs ba 9.5, ea bobeli feela ho daemane e thata ka ho fetisisa lefatšeng (10). E na le conductivity e ntle ea mocheso, ke semiconductor, 'me e khona ho hanela oxidation ka mocheso o phahameng.
