Lix faa'iido oo cadaadiska atmospheric sinteed silikon carbide iyo codsiga dhoobada carbide silikon

Cadaadiska atmospheric sintered silicon carbide hadda looma isticmaalo sida abrasive, laakiin in ka badan sida walxo cusub, waxaana si ballaaran loogu isticmaalaa alaabada teknoolajiyada sare, sida dhoobada laga sameeyay alaabta silikon carbide. Haddaba waa maxay faa'iidooyinka lixda ah ee cadaadiska atmospheric sintering silicon carbide iyo codsiga dhoobada silikoon carbide?

Lix faa'iidooyin oo cadaadiska atmospheric ah oo sinteed walxaha carbide silicon:

1. Cufnaanta hoose

Qalabka silikon carbide wuxuu leeyahay cufnaanta hoose marka loo eego birta, taas oo ka dhigaysa qalab fudud.

2. Iska caabin daxalka

Qalabka silikoon carbide wuxuu leeyahay barta dhalaalaysa sare, kimikal kiimikaad, caabbinta shoogga kulaylka, silikoon carbide waxaa loo isticmaalaa abrasives, kilns dhoobada, silicon carbide bannaan, waxaa loo isticmaali karaa in warshadaynta iyo dhalidda leh foornada distillation dhululubada toosan, leben, aluminium dahaarka unugyada elektrolytic , tungsten, foornada yar yar iyo alaabada kale ee silikoon carbide dhoobada.

3, Heerkulka sare, isugeynta fidinta kulaylka waa la dhimay

Walxaha Silicon carbide waxaa lagu soo saaraa heerkul sare. Deegaannada heerkulku sarreeyo qaarkood, agabka u baahan awoodda farsamaynta iyo habaynta saxnaanta ee ceramics-ka silikoon carbide ay gaadhi karto ayaa loo baahan yahay. Heerkulka sare ee carbide silicon wuxuu ku saabsan yahay 800, heerkulka birtana waa 250 kaliya. Xisaabinta adag, celceliska fidinta kuleylka kuleylka ee carbide silicon ee kala duwan ee 25 ~ 1400 waa 4.10-6 / C. Isku-xidhka balaadhinta kulaylka ee carbide silikoon ayaa la cabbiraa, natiijaduna waxay muujinaysaa in qadarku aad uga yar yahay kan abrasives kale iyo qalabka heerkulka sare.

4, dhaqdhaqaaqa kulaylka sare

Dhaqdhaqaaqa kulaylka ee qalabka silikoon carbide waa mid sarreeya, taas oo ah muuqaal kale oo muhiim ah oo ka mid ah sifooyinka jireed ee silikoon carbide. Dareenka kulaylka ee carbide silikoon aad ayuu uga weyn yahay kuwa kale ee refractories iyo abrades, oo ku saabsan 4 jeer ka corundum. Silicon carbide waxay leedahay koronto yar oo balaadhinta kulaylka iyo dhaqdhaqaaqa kulaylka sare, sidaa darteed qaybta shaqada waxaa la kulmi doona cadaadis kulayl yar inta lagu jiro kuleylka iyo qaboojinta. Tani waa sababta qaybaha SiC ay si gaar ah ugu adkaysanayaan shoogga.

5, xoog farsamo sare, qallafsanaan wanaagsan

Awoodda farsamada ee walxaha silikoon carbide waa mid aad u sarreeya, ka hortagaya cilladaha walxaha. Silikon carbide waxa uu leeyahay awood farsamo oo ka sarraysa corundum.

6, adkeysi badan iyo xirashada caabbinta

Qalafsanaanta qalabka silikoon carbide waa mid aad u sarreeya, iyo adkaanta farqiga Moss waa 9.2 ~ 9.6, oo kaliya marka loo eego dheeman iyo tungsten carbide. Marka la barbar dhigo qalabka birta birta ah, waxa ay bixisa adkeysi sare, isxigxiga hoose ee is jiid jiidka, khilaaf yar, qalafsanaan yar oo dusha sare ah iyo iska caabin wanaagsan oo xidhidh la'aan. Intaa waxaa dheer, waxay u adkaysataa walxaha dibadda, hagaajinta dulqaadka dusha sare. Silicon carbide silikoon ah oo la shiiday oo cadaadiska jawiga hoostiisa ku jiro

Codsiga cadaadiska atmospheric ceramics sinteed silikoon carbide

1, wax soo saarka silikoon carbide ee ceramics gaar ah

Qalabka silikoon carbide waa walxo leh engegnaan sare iyo qiimo jaban, kaas oo soo saari kara alaabada silikoon carbide, sida silikoon carbide shaabadood, gacmo-gacmeed silikoon carbide, taarikada carbide silikoon, profiles carbide silicon, iwm, kaas oo lagu dabaqi karo shaabadaha farsamada iyo bambooyin kala duwan. Silicon carbide silikoon ah oo la shiiday oo cadaadiska jawiga hoostiisa ku jiro

2, wax soo saarka zirconia ee ceramics gaar ah

dhoobada Zirconia waxay leedahay conductivity ionic sare, xasilooni kiimikaad wanaagsan iyo xasilloonida qaab dhismeedka, oo waxay noqotay wax si weyn loo bartay oo loo isticmaalo qalab elektrolyt ah. By hagaajinta habka wax soo saarka ee zirconia ku salaysan filimka electrolyte, yaraynta heerkulka shaqada iyo kharashka wax soo saarka ee alaabtan, iyo ku dadaalaya in la gaaro warshadaha sidoo kale waa jihada muhiimka ah ee cilmi mustaqbalka.
