Ukwenziwa njaniiityhubhu ze-silicon carbide eziko? Okokuqala, kufuneka sikuqinisekise okoi-silicon carbideyeyona nto iphambili ekrwada, kwaye i-silicon carbide yenziwa emva kobushushu obuphezulu. Izinto ezifunyenweyo zinokumelana nobushushu obuphezulu, ukuhanjiswa kwe-thermal ngokukhawuleza, ukomelela okuphezulu, ukuqina okuphezulu, ukuxhathisa ukunxiba kakuhle, ukuxhathisa ukothuka kwe-thermal, ukuhanjiswa kakuhle kwe-thermal, ukumelana ne-oxidation elungileyo kunye neminye imisebenzi egqwesileyo.
Emva kokuba uxhotyiswe ngesigqubuthelo esikhethekileyo sokufudumala kweqondo eliphezulu, thintela isisombululo sesinyithi kwi-corrosion ye-electric heat element, ngaloo ndlela ukhusela into yokufudumala yombane. Iimpawu zayo ezahlukeneyo zingcono kuneiityhubhu ze-silicon carbide ezikoyeemveliso ezahlukeneyo zegraphite, kwaye ine-conductivity elungileyo ye-thermal kunye nokumelana ne-oxidation. Ngokuphucula inkqubo yokuvelisa ifilimu ye-zirconia esekelwe kwi-electrolyte, iingcali zinciphisa ubushushu bokusebenza kunye neendleko zokuvelisa ezi zinto, kwaye zizame ukuphumeza ushishino, olukwayindlela entsha ebalulekileyo ye-silicon carbide kwixesha elizayo. I-ionic conductivity ephezulu, ukuzinza kakuhle kweekhemikhali kunye nokuzinza kwesakhiwo se-zirconia ceramics ziye zafundwa ngempumelelo kwaye zisetyenziswa ngokubanzi njengezinto ze-electrolyte.
Iipropati kunye neendlela ze-sintering zeiityhubhu ze-silicon carbide ezikoziyaziswa. I-silicon carbide furnace ityhubhu ayinayo kuphela iimpawu zamandla aphezulu obushushu kunye nokumelana nokunyuka. Ukumelana nokunxiba, amandla obushushu begumbi, i-coefficient ephantsi ye-friction, ukumelana nokugqwala. Iyakwazi ukusebenza kumaqondo okushisa e-1600 kwaye iyaziwa ukuba inokumelana ne-oxidation kwizinto eziphathekayo. Ityhubhu ye-Silicon carbide furnace ine-advantageness ephezulu ye-brittleness kunye nokuqina okuphantsi kwe-fracture. Kwimveliso kamva, ukuqina kunye namandla kunokuphuculwa ngokudibanisa i-fiber, i-whisker kunye ne-particle.
I-Silicon carbide yinto enhle kakhulu yokumelana nokubola, sinokuyisebenzisa ukwenza iityhubhu zesithando somlilo kunye nezinye iimveliso. Xa i-silicon carbide isetyenziselwa ukuvelisa iityhubhu zesithando somlilo, kukho iindlela ezahlukeneyo zokutshisa ezifana nokutshisa okuphantsi, umkhuhlane ophezulu, ukuveliswa okuvaliweyo, okunokuthi kukhethwe ngokwemeko yokwenyani yokucubungula ukuphucula ukusebenza kakuhle. Uxinzelelo olushushu kunye nobushushu obuphezulu boxinzelelo lwe-isostatic kunokuvelisa ukuxinana okuphezuluityhubhu ye-silicon carbide eziko, ubushushu be-sintering phakathi kwe-150 ~ 2100℃. I-silicon carbide inzima ukwenza iimilo ezinzima kunye neemveliso zexabiso eliphezulu. I-silicon carbide reaction sintering yi-silicon kunye ne-graphite powder kumlinganiselo othile wohlaza olushushu ukuvelisa -SiC. Le ndlela ivelisa i-silicon carbide kunye nobushushu obuphantsi bokutsha. Nangona kunjalo, ezinye ze-silicon zamahhala zihlala kwi-billet eluhlaza, ngoko ke umenzi we-lining ukholelwa ukuba oku kunciphisa i-high-temperature mechanical properties kunye nokusetyenziswa kwayo kwi-acids eqinile kunye neziseko.
Ngokumalunga nenkqubo yokunyakaza kwetyhubhu ye-silicon carbide furnace, emva kokuveliswa kwetyhubhu ye-silicon carbide furnace, ukuba ikhutshelwe ngaphandle kwe-slot yenkqubo, ayikho enye ingxaki eyingozi kakhulu. Ingaqinisekiswa njani ingqibelelo yayo kwindawo enjalo. I-silicon carbide furnace tube eveliswayo ifakwe kwi-tube groove ekupheleni kwe-counterweight plate, kwaye ityhubhu yesithando somlilo igxininiswe ngokudityaniswa kwe-tape yokubopha kunye ne-buckle. Qhoboshela isiqhoboshi esisusiweyo kwesinye isibophelelo sepleyiti yoxinzelelo. Isiqwenga sokulungiswa kwisiphelo esisezantsi sentambo sidibaniswe ne-groove ehleliweyo ebekwe phezu kwendawo ye-counterweight plate, kwaye i-pulley iphakanyiswe kwindawo efanelekileyo ngokusebenza kokutshintsha. Isiphelo sangaphambili sebhokisi yombane yentonga yokutshixa iyasuswa, kwaye intonga yesilayidi idluliselwe ngokudibanisa, kwaye i-counterweight plate igxininiswe kwintsika, edlala indima yokuhambisa iityhubhu ezininzi zomlilo, kwaye ukusebenza kakuhle kwandiswa ngu. amaxesha amabini. Ngale ndlela, ukusebenza kukulungele, amaqela amaninzi eepleyiti zokunyamezela amiselwe, kwaye iityhubhu zomlilo zinokulayishwa kusetyenziswa i-tube groove ebekwe kwipleyiti yokunyamezela, ephucula ubungakanani bokuhambisa iityhubhu zesithando somlilo kunye nomthamo wokuhambisa. imibhobho yomlilo. I-pad non-slip pad enokufakwa kwi-tube groove isetyenziselwa ukukhusela ityhubhu yesithando somlilo.
