Nxiba umbhobho we-Ceramic onganyangekiyo weSilicon carbide
I-Silicon carbide ceramic: Ubulukhuni be-Moh yi-9.0 ~ 9.2, ngokuchasana okugqwesileyo kukhukuliseko kunye nokugqwala, ukuxhathisa okugqwesileyo kwe-abrasion kunye ne-anti-oxidation. Inamandla ka-4 ukuya kwe-5 kune-nitride ebotshelelwe kwi-silicon carbide. Ubomi benkonzo buyi-7 ukuya kumaxesha angama-10 ubude ngaphezu kwezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi.
I-silicon carbide ukuxhathisa ukunxiba, yenziwe kwi-silicon carbide kunye ne-carbon kubushushu obuphezulu, yeyohlobo lwe-silicon carbide imveliso.I-silicon carbide ukunxitywa kweendawo zokuxhathisa zisetyenziswa ngokubanzi kwimigodi, ukutyumza i-ore, ukuhlolwa kunye nokuthuthwa kokunxiba okuphezulu, ulwelo oluphezulu oludlekayo, lufanelekile kakhulu kwiimveliso zoomatshini ezinobuchwephesha obuphezulu kunye noxinzelelo oluphezulu lwempompo, ukunxitywa kohlobo lwempompo yoxinzelelo, njl. Izinto.Reaction-bond silicon carbide wear resistance bushing ineempawu zokuqina okuphezulu,ukumelana nokunxiba okuphezulu,ukunganyangeki kwefuthe,ukumelana nobushushu obuphezulu,iasidi kunye nokumelana nomhlwa kwealkali njalo njalo,kwaye ubomi benkonzo obuyinyani bungaphezulu kwamaxesha ama-6 kobo be-polyurethane.Kulungele ngakumbi ukusebenza kokwahlulahlula, ugxininiso kunye nokuphelelwa ngamanzi emzimbeni kwezixhobo ezomeleleyo zokurhabula kunye ne-coarse-grained ye-silicon ifakwe ngempumelelo kwinkampani. umthengisi we-carbide ukuxhathisa iimveliso ze-ceramic, ukuqina okwesibini kuphela kwidayimani, kunye nokumelana nokunxiba okuphezulu, iimpawu zobomi benkonzo ende. Umbhobho wokuxhathisa ukunxitywa kunye nengqiniba eveliswe nge-silicon carbide ukunxiba i-lang resistance, ubukhulu bayo be-ceramic yi-6-35mm, isakhiwo kukufakela ityhubhu ye-ceramic esele idityanisiwe kwityhubhu ye-caliber ehambelanayo, kunye neglue ephakathi kunye neglue embindini unokumelana ne-ceramic ephakathi. imibhobho, ialloyi ekwaziyo ukumelana nemibhobho yentsimbi kunye nemibhobho ehlanganisiweyo yeceramic.
I-Reaction bonded silicon carbide (RBSC) ine-peformance egqwesileyo yokumelana nokunxiba, iipropathi ezilungileyo kumaqondo obushushu aphakamileyo, ukhukuliseko oluhle kunye nokumelana ne-abrasive, ezi zakhiwo zinokusetyenziswa kwizicelo ezahlukeneyo ezinje ngeentambo zemibhobho, ingqiniba ye-ceramic, imilomo yokutshiza, imilomo yokudubula kunye namalungu e-hydrocyclone.
Iilinen ze-ZPC zigqithise kakhulu iithayile kunye neelitha zentsimbi. I-ZPC silicon carbide ceramics kukuxhathisa ukothuka kwe-thermal kunye ne-abrasion resistant ekhokelela kumaxesha okuqhubela phambili kunye nokunciphisa ixesha lokuphumla.
I-reaction bonded silicion carbide ceramic (RBSIC) yinto efanelekileyo yokunxiba, efanelekile ngokukodwa kwi-abrasive eqinile, amaqhekeza arhabaxa, ukuhlelwa, ukugxininiswa, ukuphelelwa ngamanzi emzimbeni kunye neminye imisebenzi. Ngenxa yezi propati zingasentla, iI-RBSiC / i-SiSiC ye-silicon carbide liner elbow / i-liner tubeinokukhusela ngokufanelekileyo inxalenye ekunxityweni okuphezulu kunye nobushushu ukwenzela ukwandisa ubomi benkonzo yezixhobo.
