I-Silicon Carbide ye-Vickers Hardness ye-2000kg/mm2, inikeza isivikelo esingcono kakhulu sokushelela kwe-abrasion application
I-Silicon carbide ceramic: Ubulukhuni be-Moh bungu-9.0 ~ 9.2, i-Silicon Carbide ye-Vickers Hardness engu-2100kg/mm2, inikeza isivikelo esiphezulu sezinhlelo zokusebenza zokuhuzuka ezishelelayo ezinokumelana okuhle kakhulu nokuguguleka nokugqwala, ukumelana okuhle kakhulu nokuhuzuka kanye ne-anti-oxidation. Inamandla izikhathi ezi-4 kuya kwezi-5 kune-nitride eboshiwe i-silicon carbide. Impilo yesevisi yinde izikhathi eziyisi-7 kuye kweziyi-10 kunempahla ye-alumina. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi.
I-silicon carbide wear resistance, ihlanganiswa kusuka ku-silicon carbide kanye ne-carbon ekushiseni okuphezulu, iyingxenye yomkhiqizo we-silicon carbide.Izingxenye ze-silicon carbide ukuguga zisetshenziswa kabanzi ezimayini, ukuchotshozwa kwe-ore, ukuhlunga nokuthutha ukugqokwa okuphezulu, uketshezi oluphezulu olubolayo, futhi lufaneleka kakhulu emikhiqizweni yemishini enembayo ephezulu ngokunemba okuphezulu kanye nezidingo zokugqoka zomshini wokupompa njll. I-action.Reaction-bonded silicon carbide wear resistance bushing inezici zobulukhuni obuphezulu, ukumelana nokugqokwa okuphezulu, ukumelana nomthelela, ukumelana nokushisa okuphezulu, ukumelana nokugqwala kwe-asidi kanye nokunye, nempilo yangempela yesevisi ingaphezu kwezikhathi ezingu-6 kune-polyurethane.Ifaneleka ngokukhethekile ukusebenza kwezigaba, ukugxila kanye nokuphelelwa amandla kwamanzi kwe-abrasive eqinile ne-coarse-grained i-silicon esetshenziswe ngempumelelo enkampanini enziwe nge-silicon enziwe ngempumelelo. umphakeli wemikhiqizo ye-carbide wear resistance, ukuqina okwesibili kunedayimane, ukumelana nokugqokwa okuphezulu, izici zempilo ende.Ipayipi elingaguquki nendololwane elakhiwe nge-silicon carbide wear resistance lining, ugqinsi lwayo lwe-ceramic luyi-6-35mm, isakhiwo sifake ishubhu le-ceramic elivele lisikiwe epayipini lensimbi elihambisanayo, elineglue phakathi nepayipi elinobumba obufana nolwakudala uma liqhathaniswa ne-ceramic yangaphambilini. amapayipi, amapayipi ensimbi angagugi angagugi namapayipi ayinhlanganisela ye-ceramic.
I-Reaction bonded silicon carbide (RBSC) inokusebenza okuhle kakhulu kokumelana nokuguga, izakhiwo ezinhle emazingeni okushisa aphakeme, ukuguguleka okuhle nokumelana nokubi, lezi zakhiwo zingasetshenziswa ezintweni ezihlukahlukene ezifana namapayipi amapayipi, indololwane ye-ceramic, imibhobho yesifutho, imibhobho yokudubula kanye nezingxenye ze-hydrocyclone.
Amalayini e-ZPC awadlula kude kunamathayela namalayini ensimbi. I-ZPC silicon carbide ceramics ukumelana nokushaqeka okushisayo kanye nokumelana nemihuzuko okuholela ezikhathini zokugijima ezinwetshiwe kanye nesikhathi esincishisiwe sokuphumula.
I-react bonded silicion carbide ceramic (RBSIC) iyinto efanelekile engagqoki, elungele ikakhulukazi ukuhuzuka okuqinile, izinhlayiya ezimahhadla, ukuhlukaniswa, ukugxilisa ingqondo, ukuphelelwa amanzi emzimbeni nokunye ukusebenza. Ngenxa yalezi zakhiwo ezingenhla, i-I-RBSiC / SiSiC i-silicon carbide liner elbow / liner tubeingavikela ngokuphumelelayo ingxenye ekugqokeni okuphezulu kanye nezinga lokushisa ukuze kwandiswe impilo yesevisi yemishini.
