Yintoni umahluko phakathi kwe-action bonded kunye ne-sintered silicon carbide?

Xa kuziwa kwi-silicon carbide ceramics, zimbini iindidi eziphambili:impendulo ebotshelelwe kwisilicon carbidekunye ne-silicon carbide edibeneyo. Ngelixa zombini iindidi zeekeramics zibonelela ngamanqanaba aphezulu okuqina kunye nokumelana nokunxiba, kukho umahluko ophambili phakathi kwezi zimbini.

Masiqale nge-reaction bonded silicon carbide ceramics. Ezi ceramics ziphakathi kwe-85% kunye ne-90% ye-silicon carbide kwaye iqulethe i-silicon. Ubushushu babo buphezulu bokumelana ne-1380°C. Enye yeenzuzo eziphambili ze-action-bonded silicon carbide ceramics kukuba zinokulungelelaniswa nobukhulu obukhulu kunye neemilo. Oku kubenza izinto ezifanelekileyo zokudala iimveliso ezizodwa kunye nezobuchwephesha. Ukongeza, i-coefficient ephantsi yokwandiswa kunye nokumelana okugqwesileyo kokunxiba kwezi zeramics kubenza babe lukhetho oludumileyo kwishishini le-cyclone yezimayini.

I-silicon carbide engenaxinzelelo ye-sintered inomxholo ophezulu we-silicon carbide, enokufikelela ngaphezu kwe-99%, kwaye ubushushu obuphezulu bokuxhathisa yi-1650 ° C. I-coefficient ethile yokwandisa yaziswa ngexesha lenkqubo ye-sintering, eyenza i-Sintered sintered engenaxinzelelo i-SiC ilungele ukuvelisa iindawo ze-SiC ezichanekileyo. Ngenxa yokuchaneka kwayo okuphezulu, i-silicon carbide engenaxinzelelo isoloko isetyenziselwa ukwenza ukubumba kunye neendawo ezichanekileyo ezixhathisayo.

Ukongeza kwimibumbo echanekileyo kunye neengxenye zokunxiba, izixhobo ze-kiln zokuphela kwesiphelo kwishishini lemichiza zinokuthatha ithuba lokumelana nobushushu obuphezulu be-silicon carbide engenaxinzelelo. Kwabo bafuna iityhubhu zokutshintshiselana ngobushushu ezisebenzayo zezixhobo zabo zokusetyenzwa kweekhemikhali, i-silicon carbide engenaxinzelelo lwe-sintered ngokuqinisekileyo lukhetho olusebenzayo.

Ngokubanzi, i-reaction bonding kunye ne-stressless sintering ye-ceramics ye-SiC, nangona nganye ineenzuzo zayo kunye nokungalunganga, ifanelekile kumashishini ahlukeneyo kunye nezicelo. Ukuba ufuna imveliso ekhethekileyo okanye enkulu enokumelana nokunxiba, iikeramics ze-silicon carbide zeceramics zinokuba lukhetho olufanelekileyo kuwe. Kwiindawo ezibuthathaka ngakumbi ezifuna ukumelana nobushushu obuphezulu, i-silicon carbide engenaxinzelelo inokuba lolona khetho lungcono. Nokuba loluphi uhlobo lwe-silicon carbide ceramic oyikhethayo, unokuqiniseka ukuba iya kubonelela ngokuzinzileyo kunye nozinzo olufunwa yiprojekthi yakho.
