Guryaha silikoon carbide fal-celin-ku-daran iyo isticmaalka ugu muhiimsan? Silicon carbide waxa kale oo lagu magacaabi karaa carborundum ama ciid aan dabci lahayn, waa iskudhis aan organic ahayn, oo loo qaybiyo carbide silicon cagaaran iyo carbide silicon madow laba. Ma taqaanaa sifooyinka iyo isticmaalka ugu muhiimsan ee silikoon carbide? Maanta, waxaan soo bandhigi doonaa sifooyinka iyo isticmaalka ugu muhiimsan ee carbide silicon.
Silicon carbide sintering falcelin ah waa isticmaalka ciid quartz, calcined petroleum coke (ama coking dhuxusha), slag alwaax (wax soo saarka ee carbide silicon cagaaran u baahan tahay in lagu daro milixda cuntada) iyo alaabta kale ee cayriin, iyada oo foornada kululaynta koronto joogto ah dhalaalidda heerkul sare.
Astaamaha kaarbiide silikoon ee fal-celin-celin ah:
1. Xakamaynta kulaylka iyo isku xidhka balaadhinta kulaylka ee carbide silicon. Sida nooc ka mid ah walxaha dib-u-celinta, lebenka carbonized ayaa leh iska caabin aad u fiican oo naxdin leh. Tani waxay inta badan ku muujisaa kuleylkeeda xoog leh (xilliga wareejinta kulaylka) iyo kororka fidinta kulaylka oo aad u hooseeya.
2, conductivity ee carbide silicon. Silikon carbide waa wax semiconductor ah, conductivity ka duwan yahay nooca iyo qadarka wasakhda la gelin crystallization, iyo iska caabin ah oo ku dhex 10-2-1012Ω · cm. Waxaa ka mid ah, aluminium, nitrogen iyo boron waxay saameyn weyn ku leeyihiin dhaqdhaqaaqa silikoon carbide, iyo conductivity of silicon carbide leh aluminium badan ayaa si aad ah u kordheysa.
3. Iska caabbinta silikoon carbide. Iska caabbinta silikoon carbide waxay isbeddeshaa isbeddelka heerkulka, laakiin gudaha heerkul gaar ah iyo sifooyinka heerkulka birta iska caabbinta ayaa dib loo rogaa. Xidhiidhka u dhexeeya iska caabinta iyo heerkulka silikoon carbide waa mid aad u adag. Daawashada fal-celinta-carbidhida silikoon-ka-soo-baxa waxay kordhisaa heerkulka kor u kaca ilaa qiimo gaar ah, iyo conductivity hoos u dhaco marka heerkulku mar kale kordho.
Isticmaalka silikoon carbide:
1, Qalabka u adkaysta - inta badan waxaa loo isticmaalaa in lagu sameeyo giraangiraha ciidda, shiidida warqada ciid, dhagaxa dhagaxa, giraangiraha shiida, koollada wax lagu shiido iyo alaabta sawir-qaadista ee unugyada sawir-qaadista, unugyada sawir-qaadista iyo qaybaha shiididda dusha sare, shiidid iyo shaandhaynta.
2, wax-soo-celinta-dhamaadka sare - waxaa loo isticmaali karaa sida deoxidizer warshadaha birta ah iyo walxaha u adkaysta daxalka, si ay u sameeyaan qaybo prefabricated heerkulka sare joogto ah, qaybo go'an, iwm.
3, ceramics functional - ma aha oo kaliya in la yareeyo mugga foornada, laakiin sidoo kale hagaajinaysaa tayada alaabta foornada warshadaha, la yareeyo wakhtiga wareegga, waa wax aan toos ahayn ugu fiican ee dhoobada glaze sintering, heerkulka sare joogto ah ceramics non-oxide, ka tarjumaysa sintered porcelain.
4, biraha dhif ah - shirkadaha birta iyo birta, beerta xooga saaraya warshadaha biraha, leeyihiin codsi gaar ah.
5, kale - loo isticmaalo in lagu sameeyo daahan shucaaca fog-infrared ama saxan carbide silicon carbide qalajiyaha fog-infrared shucaaca.
Silicon carbide sababtoo ah sifooyinka kiimikada dabiiciga ah ee siman, iskudhafka wareejinta kulaylka sare, isugeynta fidinta tooska ah ee yar yar, caabbinta xirashada wanaagsan, marka lagu daro xirashada walxaha adkaysiga leh, waxaa jira qaar ka mid ah isticmaalka kale ee muhiimka ah, sida: oo leh hannaan cusub oo loogu talagalay xabagta budada silicon carbide impeller-ka centrifugal ama godka jirka dhululubada, waxay hagaajin kartaa iska caabbinta xirashada waxayna kordhin kartaa nolosha adeegga 1 ilaa 2 jeer; Loo isticmaalo in lagu sameeyo walxaha refractory heerka sare, heerkulka sare iska caabin shoogga, size yar, miisaanka fudud iyo xoogga sare, ilaalinta deegaanka iyo saamaynta badbaadinta tamarta waa cad. Silicon carbide-ka hooseeya (oo ka kooban qiyaastii 85% SiC) waa walax deoxidizing wanaagsan, kaas oo loo isticmaali karo si loo dardargeliyo heerka samaynta birta, oo ku habboon in la maareeyo halabuurka iyo hagaajinta tayada birta. Intaa waxaa dheer, silikoon carbide ayaa sidoo kale loo isticmaalaa in lagu sameeyo qalab badan oo kuleyliyaha korantada ul silicon molybdenum.
