gqoka ipayipi le-ceramic elihlanganisiwe eliqinile
I-Silicon carbide ceramic: Ubulukhuni be-Moh bungu-9.0~9.2, bukwazi ukumelana kahle 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 isuka ku-silicon carbide kanye ne-carbon ezingeni lokushisa eliphezulu, iyingxenye yomkhiqizo we-silicon carbide. izinto eziwuketshezi, futhi ezifaneleke kakhulu emikhiqizweni eyimishini enembayo ephezulu kanye nezidingo zokuvala, njengepompo yomfutho ophezulu, iphampu kazibuthe njll ukumelana nokugqoka, ukumelana nomthelela, ukumelana nokushisa okuphezulu, ukumelana nokugqwala kwe-asidi kanye ne-alkali nokunye, futhi impilo yangempela yesevisi ingaphezu kwezikhathi ezingu-6 kune-polyurethane. Izinto ezisanhlamvu ezimahhadla, zisetshenziswe ngempumelelo ezimayini eziningi.Inkampani yethu iwumphakeli wemikhiqizo yobumba eqinile ye-silicon carbide wear resistance, ukuqina okwesibili ngemuva kwedayimane, enokumelana nokugqokwa okuphezulu, izici zempilo ende.Ipayipi lokumelana nokugqokwa nendololwane okukhiqize ene-silicon carbide wear resistance lining, ugqinsi lwayo lwe-ceramic luyi-6-35mm, isakhiwo esokufaka ishubhu le-ceramic eselivele lisikiwe eshubhuni lensimbi elihambisanayo, elinengcina phakathi. amapayipi ensimbi asetshenziswa ngaphambilini, amapayipi ensimbi angagugi kanye namapayipi ayinhlanganisela yobumba.
I-Reaction bonded silicon carbide (RBSC) inokusebenza okuhle kakhulu kokungagugi, izakhiwo ezinhle emazingeni okushisa aphakeme, ukuguguleka okuhle nokumelana nokubi, lezi zakhiwo zingasetshenziswa ezinhlelweni ezihlukahlukene ezifana namapayipi amapayipi, indololwane ye-ceramic, imibhobho yesifutho, imibhobho yokudubula kanye izingxenye ze-hydrocyclone.
Amalayini e-ZPC adlula kude amalayini anamathayela kanye nensimbi. 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.

Isimo sokusebenza sepayipi le-silicon carbide ceramic ukumelana nokugqoka
Izici ezijwayelekile ze-silicon carbide zifaka:
- Ukuminyana okuphansi
- Amandla aphezulu
- Amandla okushisa aphakeme amahle (Ukusabela kuhlanganisiwe)
- Ukumelana ne-oxidation (Ukusabela kuhlanganisiwe)
- Ukumelana nokushaqeka okuhle kakhulu kwe-thermal
- Ukuqina okuphezulu nokumelana nokugqoka
- Ukumelana kwamakhemikhali okuhle kakhulu
- Ukunwetshwa okuphansi kwe-thermal kanye ne-high conductivity ye-thermal
Izicelo ezijwayelekile ze-silicon carbide zifaka:
Zisetshenziswa kakhulu ekusebenzeni ngokuguga ekushiseni okuphansi kunokuziphatha kokushisa okuphezulu. Izinhlelo zokusebenza ze-SiC zifana nezijovo ze-sandblasting, izigxivizo zephampu yamanzi ezimoto, ama-bearings, izingxenye zephampu, kanye ne-extrusion dies ezisebenzisa ubulukhuni obuphezulu, ukumelana nemihuzuko, nokungagqwali kwe-carbide ye-silicon.
- Izingxenye ze-turbine ezilungisiwe nezinyakazayo

Imboni ye-Metallurgy namandla: Isizathu sokuthi lezi zimboni ezimbili zihlanganiswe ikakhulukazi yingoba lezi zimboni zombili zine
I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
