SCSC - TH yakhala zida zatsopano zosamva kuvala kuti apange ma liner a hydrocyclone.
Zogulitsa za Silicon carbide sintered zimaphatikizapo kuuma kolimba, kulimba kwambiri komanso kutentha kwambiri. Komabe, zinthu zotere zimakhala ndi zovuta, monga kulimba mtima, fragility ndi zina zotero. Kuti zigwirizane ndi momwe hydrocyclone imagwirira ntchito, iyenera kukonzedwanso. Zhongpeng yasintha njira yake, yapanga ndikuyambitsa zida zatsopano zosagwirizana ndi chimphepo chamkuntho chomwe chimatchedwa SCSC yosamva kuvala - TH. Ndi chinthu chatsopano cha crystalline chomwe chimapangidwa ndikuwonjezera zinthu zomwe zimagwira ntchito popanga sintering silicon carbide ndikutenthedwa ndikuyankhidwa kutentha kwambiri. Zigawo zake zazikulu zamapangidwe ndi SiC, C, Mo, ndi zina. Binary kapena multivariate hexagonal pawiri kapangidwe amapangidwa mu kutentha kwambiri chilengedwe. Choncho, mankhwalawa ali ndi kuuma kwakukulu, mphamvu zambiri, kudzipaka mafuta (kutsika kochepa), anti-adhesion, kukana kwa dzimbiri komanso kutentha kwambiri.
Kapangidwe kakemidwe ndi mawonekedwe athupi akuwonetsedwa patebulo 1 ndi tebulo 2.
Gulu 1: kapangidwe ka mankhwala

Pansi pamikhalidwe yomweyi, kuyerekeza kwa katundu pakati pa SCSC － TH ndi zoumba za aluminiyamu zapamwamba zikuwonetsedwa mu Table 3.
Gulu 3: Kuyerekeza kwa katundu pakati pa SCSC － TH ndi Ai2O3

Moyo wautumiki wamphepo yamkuntho yolemetsa ndikuthandizira mapaipi osamva kuvala opangidwa ndi SCSC - TH ndi 3 ~ 5 nthawi ya Ai.2O3 ndi nthawi zopitilira 10 kuposa aloyi wosamva kuvala. Mzere wopangidwa ndi SCSC － TH ukhoza kuwonjezera kuchira kwa malasha oyera ndi 1%. Kuyerekeza moyo wautumiki wa Ai2O3 ndi SCSC - TH ndi motere:
Gulu 4: Zotsatira zofananitsa kuchokera pakulekanitsa kwa chimphepo chamkuntho chapakati (%)
