SCSC - Th tau yog tus hnav tshiab tshiab-resistant cov ntaub ntawv los tsim cov kab ntawm hydrocyclones.
Cov khoom ntawm silicon carbide sintered cov khoom muaj xws li hardness, siab zog thiab siab thermostility. Txawm li cas los xij, xws li cov khoom lag luam muaj qhov tsis zoo, xws li tsis muaj zog, tsis zoo thiab lwm yam. Txhawm rau kom yoog raws li cov haujlwm ua haujlwm ntawm hydrocychlone, nws yuav tsum tau txhim kho ntxiv. ZHongpeng tau txhim kho nws cov txheej txheem, tsim thiab qhia cov khoom hnav-resistant uas haum rau kev hnav cov khoom siv hluav taws xob hnyav uas tsis haum - th. Nws yog cov khoom siv crystalline tshiab los ntawm kev ntxiv cov kab lus hauv cov txheej txheem ntawm Sintering Silicon carbide thiab yog sintered thiab reacted nyob rau hauv siab kub. Nws lub cim tshuaj hluav taws xob tseem ceeb yog SIC, C, thiab Binary lossis multivariate hexagonal qauv tsim yog tsim nyob rau hauv kev kub ib puag ncig. Yog li ntawd, cov khoom no muaj super hardness, siab lubrice, kev sib txhuam ntawm tus kheej (tsis tshua muaj kev sib txhuam), tiv thaiv cov tshuaj nplaum, corrosion tsis kam thiab kub ua hauj.
Cov tshuaj lom neeg muaj tshuaj lom neeg thiab cov khoom siv lub cev muaj nyob hauv Table 1 thiab Rooj 2.
Rooj 1: Tshuaj lom neeg muaj pes tsawg leeg

Raws li tib qho kev mob, qhov sib piv ntawm cov khoom ntawm SCSC - Th thiab siab Alumina Ceramics yog qhia hauv Table 3.
Cov Lus 3: Kev sib piv ntawm cov khoom ntawm SCSC - Th thiab Ai2O3
| Cov khoom | Ntom ntom (g * cm3) | Mons "Hardness Nplai | Microhardness (kg * hli2) | Dabtsi yog khoov zog (mpa) | Puas Tsum |
| Ai2O3 | 3.6 | 7 | 2800 | 200 | I≤0. 15 |
| SCSC - Th | 3.02 | 9.3 | 00 | 280 | I≤0. 01 |
Cov kev pabcuam lub neej ntawm hnyav nruab nrab cyclone thiab txhawb nqa cov ris-resistant pipeline ua los ntawm SCSC - Th yog 3 ~ 5 zaug uas ntawm Ai2O3 Thiab ntau tshaj 10 lub sij hawm uas ntawm cov hnav-resistant alloy. Cov kab ntawv ua los ntawm SCSC - Th tuaj yeem nce rov qab ntawm cov thee kom huv los ntawm ntau dua 1%. Qhov kev pabcuam lub neej sib piv ntawm Ai2O3 Thiab SCSC - Th yog li hauv qab no:
Cov Lus 4: Kev sib piv cov txiaj ntsig los ntawm kev sib cais cov nyhuv ntawm ntom-nruab nrab cyclone (%)
| Cov khoom | Cov ntsiab lus <1. 5 | Cov ntsiab lus 1.5 ~ 1. 8 | Cov Ntsiab Lus> 1.8 |
| Ai2O3 kab | SCSC - Thner | Ai2O3 kab | SCSC - Thner | Ai2O3 kab | SCSC - Thner |
