SCSC - TH tau ua cov ntaub ntawv hnav-tiv taus tshiab los tsim cov kab ntawm hydrocyclones.
Cov khoom ntawm Silicon carbide sintered cov khoom muaj xws li muaj zog hardness, siab zog thiab siab thermostability. Txawm li cas los xij, cov khoom zoo li no muaj qhov tsis zoo, xws li tsis zoo toughness, fragility thiab lwm yam. Txhawm rau hloov mus rau qhov ua haujlwm ntawm hydrocyclone, nws yuav tsum tau ua kom zoo dua ntxiv. Zhongpeng tau txhim kho nws cov txheej txheem, tsim thiab nthuav tawm cov khoom siv tshiab hnav-tiv taus haum rau hnyav nruab nrab cua daj cua dub uas hu ua hnav-resistant SCSC － TH. Nws yog cov khoom siv crystalline tshiab uas tau tsim los ntawm kev ntxiv cov kab hauv cov txheej txheem ntawm sintering silicon carbide thiab raug sintered thiab reacted nyob rau hauv kub. 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 ib puag ncig kub. Yog li ntawd, cov khoom no muaj super hardness, siab zog, nws tus kheej-lubricating (tsawg txhuam), anti-adhesion, corrosion kuj thiab kub kuj.
Cov tshuaj muaj pes tsawg leeg thiab lub cev muaj zog muaj nyob rau hauv Table 1 thiab cov lus 2.

Kev pabcuam lub neej ntawm hnyav nruab nrab lub zog cua daj cua dub thiab txhawb nqa cov kav dej tiv thaiv ua los ntawm SCSC － TH yog 3 ~ 5 npaug ntawm Ai2O3 thiab ntau tshaj 10 npaug ntawm hnav-resistant alloy. Cov hauv ob sab phlu ua los ntawm SCSC － TH tuaj yeem ua kom rov qab tau cov thee huv los ntawm ntau dua 1%. Kev pabcuam lub neej sib piv ntawm Ai2O3 thiab SCSC - TH yog raws li nram no:
