Indawo yokuqhuma eqine kakhulu i-Silicon Carbide Grit

I-Junda Silicon Carbide Grit iyimithombo yezindaba eqhuma kanzima etholakalayo. Lo mkhiqizo wekhwalithi ephezulu ukhiqizwa ngendlela eyi-blocky, eyi-angular okusanhlamvu. Le midiya izophuka ngokuqhubekayo okuholela emiphethweni ebukhali, ehlabayo. Ukuqina kwe-Silicon Carbide Grit kuvumela izikhathi ezimfushane zokuqhuma uma kuqhathaniswa nemidiya ethambile.

Ngenxa yezakhiwo zayo zamakhemikhali ezizinzile, izinga eliphezulu le-thermal conductivity, i-coefficient ephansi yokwandisa ukushisa okushisayo, nokumelana okuhle nokugqokwa, i-silicon carbide inezinye izinto eziningi ezisetshenziswayo ngaphandle kokusetshenziswa njengama-abrasives. Isibonelo, i-silicon carbide powder isetshenziswa ku-impeller noma isilinda se-turbine yamanzi ngenqubo ekhethekile. Udonga lwangaphakathi lungathuthukisa ukumelana kwalo nokugqoka futhi lwandise impilo yalo yesevisi ngo-1 izikhathi ezingu-2; i-high-grade refractory material eyenziwe ngayo inokumelana nokushaqeka kokushisa, usayizi omncane, isisindo esilula, amandla aphezulu kanye nomphumela omuhle wokonga amandla. I-silicon carbide yezinga eliphansi (equkethe cishe u-85% we-SiC) iyi-deoxidizer enhle kakhulu. Ingakwazi ukusheshisa isivinini sokwenza insimbi, futhi yenze lula ukulawula ukwakheka kwamakhemikhali futhi ithuthukise ikhwalithi yensimbi. Ngaphezu kwalokho, i-silicon carbide nayo isetshenziswa kabanzi ukwenza izinti ze-silicon carbide zezinto zokushisa zikagesi.

I-silicon carbide inobunzima obuphakeme kakhulu, nobulukhuni be-Mohs obungu-9.5, okwesibili ngemuva kwedayimane elinzima kakhulu emhlabeni (10). Ine-thermal conductivity enhle kakhulu, iyi-semiconductor, futhi ingamelana ne-oxidation emazingeni okushisa aphezulu.

Ngenxa yezakhiwo zayo zamakhemikhali ezizinzile, izinga eliphezulu le-thermal conductivity, i-coefficient ephansi yokwandisa ukushisa okushisayo, nokumelana okuhle nokugqokwa, i-silicon carbide inezinye izinto eziningi ezisetshenziswayo ngaphandle kokusetshenziswa njengama-abrasives. Isibonelo, i-silicon carbide powder isetshenziswa ku-impeller noma isilinda se-turbine yamanzi ngenqubo ekhethekile. Udonga lwangaphakathi lungakhuphula ukumelana nokugqoka futhi lukhulise impilo yalo yesevisi ngo-1 izikhathi ezingu-2; impahla ephikisayo eyenziwe ngayo inokumelana nokushaqeka kokushisa, usayizi omncane, isisindo esilula, amandla aphezulu kanye nomphumela omuhle wokonga amandla.
