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 nekhabhoni kubushushu obuphezulu, yeyohlobo lwemveliso ye-silicon carbide. Ulwelo, olukwafaneleke kakhulu kwiimveliso zoomatshini ezichaneke kakhulu kunye neemfuno zokutywinwa, ezinje ngempompo yoxinzelelo oluphezulu, impompo yemagnethi njl njl Ukumelana nokunxiba, ukumelana nempembelelo, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-asidi kunye nealkali kunye nokunye, kwaye ubomi benkonzo bokwenyani bungaphezulu kwamaxesha ama-6 kune-polyurethane. izixhobo ezirhabaxa-grained, iye yasetyenziswa ngempumelelo kwimines ezininzi.Inkampani yethu yi-silicon carbide ukunxiba ukuxhathisa iimveliso zeceramic umboneleli, ukuqina okwesibini kuphela idayimani, kunye nokumelana eliphezulu ukunxiba, iimpawu ubomi benkonzo elide.Umbhobho yokumelana ukunxiba kunye nengqiniba eziveliswe kunye nesilicon carbide ukunxiba ukuxhathisa lining, ubukhulu bayo eludongeni lweceramic yi-6-35mm, ulwakhiwo kukufakela ityhubhu yeceramic esele itshixiwe kwityhubhu yentsimbi ehambelanayo, kunye neglu phakathi. imibhobho yentsimbi edityanisiweyo eyamkelweyo yangaphambili, imibhobho yentsimbi edityanisiweyo engagugiyo kunye nemibhobho ehlanganisiweyo yeceramic.
I-Reaction bonded silicon carbide (RBSC) inokumelana nokunxiba okugqwesileyo, 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 amacandelo 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.
