Silicon carbide ceramic: Ho thatafala ha Moh ke 9.0 ~ 9.2, e nang le khanyetso e ntle ea khoholeho ea mobu le ho bola, ho hanyetsa ka mokhoa o babatsehang oa abrasion le anti-oxidation. E matla ka makhetlo a 4 ho isa ho a 5 ho feta nitride bonded silicon carbide. Bophelo ba ts'ebeletso bo bolelele ba makhetlo a 7 ho isa ho a 10 ho feta lisebelisoa tsa alumina. MOR ea RBSiC ke 5 ho linako tse 7 tsa SNBSC, e ka sebelisoa bakeng sa libopeho tse rarahaneng haholoanyane.
Silicon carbide wear resistance, e entsoe ho tloha silicon carbide le carbon at high temperatures, ke ea mofuta oa silicon carbide product.The silicon carbide wear resistance parts, e sebelisoa haholo merafong, ho senya le ho tsamaisa thepa e phahameng, maro a phahameng a senyang, hape a loketse haholo bakeng sa lihlahisoa tsa mechine tse nang le ho nepahala ho phahameng le litlhoko tse phahameng tsa pompo, joalo-joalo. material.Reaction-bonded silicon carbide wear resistance bushing e na le litšobotsi tsa boima bo phahameng, ho hanyetsa ho hoholo, ho hanyetsa mocheso, ho hanyetsa mocheso, acid le alkali corrosion resistance, joalo-joalo, 'me bophelo ba sebele ba tšebeletso bo feta makhetlo a 6 ho feta a polyurethane. carbide wear resistance ceramic dihlahiswa tsa thepa, boima ba bobeli ke daemane, bo nang le khanyetso e phahameng, bophelo bo bolelele ba tšebeletso. Pipe ea ho hanyetsa le setsoe e hlahisitsoeng ka silicon carbide wear resistance line, botenya ba eona ba ceramic ke 6-35mm, mohaho ke oa ho kenya tube ea ceramic e seng e kentsoe ka har'a tube e tsamaisanang ea tšepe ea caliber, le sekhomaretsi se bohareng ha se bapisoa le thepa ea ceramic e fetileng. liphaephe, liphaephe tsa tšepe tse manganga le lipeipi tse entsoeng ka ceramic.
Reaction bonded silicon carbide (RBSC) e na le ts'ebetso e ntle ea ho sesa, thepa e ntle mochesong o phahameng, khoholeho e ntle le khanyetso e matla, thepa ena e ka sebelisoa lits'ebetsong tse fapaneng joalo ka liphaephe, setsoe sa ceramic, li-nozzles tsa spray, li-nozzles tse thunyang le likarolo tsa hydrocyclone.
Masela a ZPC a feta hōle lithaele tsa lithaele le tsa tšepe. Li-ceramics tsa ZPC silicon carbide li hanyetsa mocheso oa mocheso le ho haneloa ke abrasion e hlahisang nako e telele ea ho matha le nako e fokotsehileng ea nako.
The reaction bonded silicion carbide ceramic (RBSIC) ke thepa e sa tsitsang ea ho roala, e loketseng ka ho khetheha bakeng sa li-abrasive tse matla, likaroloana tse mahoashe, lihlopha, mahloriso, ho felloa ke metsi 'meleng le ts'ebetso e meng. Ka lebaka la thepa e ka holimo, theRBSiC / SiSiC silicon carbide liner elbow / liner tubee ka sireletsa karolo ka katleho ho tloha ho apara le mocheso o phahameng e le ho lelefatsa bophelo ba tšebeletso ea thepa.
