I-Silicon nitride ceramic

Silicon nitride ceramic Umfanekiso obonakalayo

Inkcazelo emfutshane:

Kwishishini lokulungisa i-aluminium, kukho iinkqubo ezininzi kunye namacandelo abandakanyekayo ekuthuthweni nasekulawuleni i-aluminium etyhidiweyo, njengamajoyina, imibhobho, iitanki kunye nemibhobho. Kwezi nkqubo, ukusetyenziswa kwe-Silicon nitride ceramic ene-conductivity ephantsi ye-thermal, ukuxhathisa ukothuka kwe-thermal, kunye ne-aluminium engasiyo intonga etyhidiweyo yindlela yexesha elizayo.

Isicelo seMveliso

● Xa kuthelekiswa ne-aluminium silicate ye-ceramic fiber, i-Silicon nitride ceramic inamandla aphezulu kunye nepropati engcono yokungamanzi. Xa isetyenziselwa iiplagi, iityhubhu ze-sprue kunye nezinyusi eziphezulu ezishushu kwishishini le-Foundry, inokuthembeka okuphezulu kunye nobomi obude benkonzo.

● Zonke iintlobo zeetyhubhu zokunyuka ezisetyenziselwa ukuphosa umxhuzulane, ukuphoswa koxinzelelo oluhlukeneyo kunye nokuphosa uxinzelelo oluphantsi kuneemfuno eziphezulu zokugquma, ukuxhathisa ukutshatyalaliswa kwe-thermal kunye nepropati engamanzi. I-Silicon nitride ceramic lolona khetho lungcono kwiimeko ezininzi.

Imiqathango yokusetyenziswa

● Amandla e-flexural ye-Silicon nitride ceramic yi-40-60MPa kuphela, nceda ube nomonde kwaye uqikelele ngexesha lofakelo ukuze ugweme umonakalo ongeyomfuneko wamandla angaphandle.

● Kwizicelo apho kufuneka ukulingana okuqinileyo, ukuhluka okuncinci kunokupholiswa ngononophelo nge-sandpaper okanye amavili abrasive.

● Ngaphambi kokufakela, kucetyiswa ukuba ugcine umkhiqizo ukhululekile kumswakama kwaye uyomise kwangaphambili.

Iinzuzo eziphambili:

Amandla aphezulu kunye nobunzima: I-Silicon nitride inomdibaniso ochukumisayo wamandla aphezulu kunye nobunzima, ukubonelela ngokugqwesileyo kunye nokuchasana kwempembelelo naphantsi kweemeko ezinzima.
Okugqwesileyo kweThermal Shock Resistance: I-Silicon nitride ceramics inokumelana nokutshintsha kweqondo lokushisa ngokukhawuleza ngaphandle kokuqhekeka okanye ukulahlekelwa yingqibelelo, okwenza kube yinto efanelekileyo kwiindawo eziphezulu zokushisa, ezifana neziko okanye iinjini.
Ukumelana nobushushu obuphezulu: Ngomgangatho ophezulu wokunyibilika kunye nokukwazi ukugcina amandla kumaqondo aphezulu aphezulu, i-silicon nitride ifanelekile kwizicelo ezifuna ukuzinza kwexesha elide phantsi kobushushu obuphezulu.
Ukwandiswa kweThermal ephantsi: Esi sixhobo se-ceramic sine-coefficient ephantsi yokwandiswa kwe-thermal, eqinisekisa ukuzinza kwe-dimensional ngexesha lokutshintsha kweqondo lokushisa, ukunciphisa umngcipheko we-thermal deformation.
Okugqwesileyo kokuNchasa ukuMhlwa: I-Silicon nitride ixhathisa kakhulu kwi-corrosion yeekhemikhali, kubandakanywa i-acids, i-alkalis, kunye nesinyithi esityhidiweyo, okwenza ukuba ifaneleke kwiindawo ezibuhlungu zeekhemikhali.
Ikhaphukhaphu: Ngaphandle kwamandla ayo, i-silicon nitride ilula xa ithelekiswa nesinyithi, iyenza ibe luncedo kumashishini afana ne-aerospace kunye nemoto, apho ukunciphisa ubunzima kubalulekile.
Ukufakwa koMbane: Iiseramics ze-silicon nitride zineempawu ezigqwesileyo zokugquma umbane, zizenza zilungele ukusetyenziswa kombane kunye ne-elektroniki ezifuna imathiriyeli ene-thermal ephezulu kunye nokumelana nombane.
Biocompatibility: Le ceramic kwakhona i-biocompatible, ivumela ukuba isetyenziswe kwizixhobo zonyango, ngakumbi kwizicelo ze-orthopedic ezifana nokufakelwa.
