Ubume obukhethekileyo beSilicon Carbide iCeramic entsha yezinto

Ubume obuKhethekileyo beSilicon Carbide Isixhobo esitsha seCeramic Umfanekiso obonakalisiweyo

Inkcazelo emfutshane:

I-silicon carbide ye-reaction-bounded (si-sic) sic ceramic, yenziwe iqanda le-porosity ngokugcwalisa i-porosity evulekileyo ngesinyithi sesilicon (si). Ngenxa yeempawu zayo zero porosity, i-thermal conductivity ingaphezulu kabini kwe-oxide edityaniswe sic's, amandla okugoba angaphezulu kwamaxesha ama-5 aphezulu xa kuthelekiswa ne-oxide ebotshwe sic. Uphawu olukhethekileyo lweSic kukukwazi ukugcina amandla aphezulu ukusuka kubushushu begumbi ukuya kuthi ga kwi-1,380°c. Kwakhona inokumelana ne-oxidation ephezulu kakhulu, ukumelana neekhemikhali ...

Iithegi zeMveliso

I-silicon carbide ye-reaction-bond (si-sic) sic ceramic, yenziwe iqanda le-porosity ngokugcwalisa i-porosity evulekileyo ngesinyithi sesilicon (si). Ngenxa yeempawu zayo zero porosity, i-thermal conductivity ingaphezulu kabini kwe-oxide edityaniswe sic's, amandla okugoba angaphezulu kwamaxesha ama-5 aphezulu xa kuthelekiswa ne-oxide ebotshwe sic.
Uphawu olukhethekileyo lweSic kukukwazi ukugcina amandla aphezulu ukusuka kubushushu begumbi ukuya kuthi ga kwi-1,380°c. Kwakhona inokumelana ne-oxidation ephezulu kakhulu, ukuxhathisa imichiza kunye nokumelana nokunxiba. Isetyenziswa njenge-boam, i-roller, i-tube burner ekhanyayo kunye ne-nozzle yokushisa njl.
I-Reaction Bonded Silicon Carbide inyamezela uluhlu olubanzi lweeasidi kunye nealkali. Kwaye ngokusebenza okugqwesileyo kokuqina okuphezulu, ubunzima obuphezulu, ukumelana nokunxiba okuphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa umhlwa. Iindidi ezahlukeneyo zeemilo zamalungu akhethekileyo zilungele imigodi, i-petrochemical, i-metallurgical production, i-aerospace kunye nemizi-mveliso yenyukliya, njengendawo yokusingqongileyo ethile. Sinokwenza naziphi na iisayizi ezinikezelweyo ngokwesicelo somthengi.

Ukumelana nokunxiba, amandla obushushu obuphezulu kunye nokumelana nomhlwa kwenza i-Reaction Bonded SiC ibe yimathiriyeli efanelekileyo kumalungu okunxiba, anjengezikrufu, iipleyiti kunye ne-impellers. Isenokusetyenziswa kwakhona kwii-thrust bearings ezinokuthwala imithwalo ephezulu kakhulu kulwelo olungcoliseke kakhulu.

ISilicon Carbide SiC (SiSiC/RBSiC) Iimpawu:

Ukukrazuka / ukuxhathisa ukonakala
Iimpawu ezigqwesileyo zokothuka kwe-thermal
Ukuxhathisa okugqwesileyo kwe-oxidation
Ulawulo olulungileyo lweemilo ezintsonkothileyo
I-conductivity ephezulu ye-thermal
Ukusebenza okuphuculweyo
Ubomi obude phakathi kokutshintshwa / ukwakha kwakhona
Ukuchasa ukubola
Ukumelana okuPhezulu kokunxiba
Amandla kwiqondo lobushushu eliphezulu ukuya kuthi ga kwi-1380°C

Ngaphambili: Nxiba ukumelana ne-SiC liner

Okulandelayo: I-silicon ye-carbide ye-ceramic efakwe umbhobho kunye ne-elbow

I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubulukhuni be-Moh yi-9 (ubulukhuni be-Moh entsha yi-13), kunye nokuchasana okugqwesileyo kukhukuliseko kunye nokugqwala, i-abrasion egqwesileyo - ukuxhathisa kunye ne-anti-oxidation. Ubomi benkonzo yemveliso ye-SiC yi-4 ukuya kwamaxesha ama-5 ubude ngaphezu kwe-92% yezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi. Inkqubo yekoteyishini ikhawuleza, ukuhanjiswa kuthenjisiwe kwaye umgangatho ungowesibini. Sihlala sizingisa ukucela umngeni kwiinjongo zethu kwaye sibuyisele iintliziyo zethu kuluntu.
