I-SCSC -TH ibilokhu iyizinto ezintsha ezingagugi ukukhiqiza ama-liner ama-hydrocyclones.
Izakhiwo zemikhiqizo ye-silicon carbide e-sintered zihlanganisa ubulukhuni obuqinile, amandla aphezulu kanye nokuqina okuphezulu kokushisa. Kodwa-ke, uhlobo olunjalo lwemikhiqizo lunezinkinga, njengokuqina okubi, ubuthakathaka njalo njalo. Ukuze ivumelane nezimo zokusebenza ze-hydrocyclone, idinga ukuthuthukiswa kakhulu. I-Zhongpeng ithuthukise inqubo yayo, yathuthukisa futhi yaletha into entsha engagugi efanele isiphepho esindayo esiphakathi nendawo ebizwa ngokuthi i-SCSC -TH engagugi. Iyinto entsha yekristalu eyenziwe ngokungeza izakhi zokulandelela enkambisweni yokusila i-silicon carbide futhi i-sintered futhi isabele ekushiseni okuphezulu. Izingxenye zayo eziyinhloko zesakhiwo samakhemikhali yi-SiC, C, Mo, njll. Isakhiwo se-Binary noma multivariate hexagonal compound sakhiwa endaweni eshisa kakhulu. Ngakho-ke, lo mkhiqizo unobulukhuni obukhulu, amandla aphezulu, ukuzigcoba (ukungqubuzana okuphansi), ukulwa nokunamathela, ukumelana nokugqwala kanye nokumelana nokushisa okuphezulu.
Ukwakheka kwamakhemikhali kanye nezakhiwo zomzimba kuboniswe kuThebula 1 kanye nethebula 2.
Ithebula 1: ukwakheka kwamakhemikhali

Ngaphansi kwezimo ezifanayo, ukuqhathaniswa kwezakhiwo phakathi kwe-SCSC -TH kanye ne-aluminium ceramics ephezulu kuboniswe kuThebula 3.
Ithebula 3: ukuqhathanisa izakhiwo phakathi kwe-SCSC -TH ne-Ai2O3
| Izinto | Ubuningi (g *cm3) | Isikali sobulukhuni bukaMons | Ubulukhuni obuncane (kg*mm)2) | Amandla okugoba (i-MPa) | Ukuguguleka |

| I-SCSC - TH | 3.02 | 9.3 | 3400 | 280 | ≤0. 01 |
Isikhathi senkonzo yesiphepho esindayo sesistimu esiphakathi nendawo kanye nepayipi elisekelayo elingagugi elenziwe nge-SCSC -TH liphindwe kathathu kuya kahlanu kune-Ai2O3 futhi ngaphezu kokuphindwe kayishumi kune-alloy engagugi. Ulwelwesi olwenziwe nge-SCSC -TH lungandisa ukubuyiswa kwamalahle ahlanzekile ngaphezu kuka-1%. Ukuqhathaniswa kwempilo yesevisi ye-Ai2O3 futhi i-SCSC - TH ingokulandelayo:
Ithebula 4: Imiphumela yokuqhathanisa evela emphumeleni wokuhlukaniswa kwesiphepho esiphakathi nendawo (%)
