SCSC - TH tau yog cov ntaub ntawv tshiab uas tiv taus kev hnav los tsim cov liners ntawm hydrocyclones.
Cov khoom ntawm Silicon carbide sintered khoom muaj xws li muaj zog tawv, muaj zog siab thiab thermostability siab. Txawm li cas los xij, cov khoom zoo li no muaj qhov tsis zoo, xws li tsis muaj zog, tsis yooj yim tawg thiab lwm yam. Yuav kom hloov kho rau cov xwm txheej ua haujlwm ntawm hydrocyclone, nws yuav tsum tau txhim kho ntxiv. Zhongpeng tau txhim kho nws cov txheej txheem, tsim thiab qhia cov khoom siv tshiab uas tsis yooj yim hnav uas haum rau cov cua daj cua dub nruab nrab uas hu ua hnav-resistant SCSC - TH. Nws yog cov khoom siv crystalline tshiab synthesized los ntawm kev ntxiv cov ntsiab lus hauv cov txheej txheem ntawm sintering silicon carbide thiab raug sintered thiab reacted hauv qhov kub siab. Nws cov khoom siv tshuaj lom neeg tseem ceeb yog SiC, C, Mo, thiab lwm yam. Binary lossis multivariate hexagonal compound qauv yog tsim nyob rau hauv qhov chaw kub siab. yog li ntawd, cov khoom no muaj super hardness, muaj zog siab, self-lubricating (kev sib txhuam tsawg), tiv thaiv kev nplaum, tiv thaiv corrosion thiab tiv thaiv kub siab.
Cov tshuaj lom neeg thiab cov khoom siv lub cev tau qhia nyob rau hauv Rooj 1 thiab Rooj 2.
