Astaamaha Silicon Carbide Rod

Guryaha jidhka

Adag sare iyo xoog sare: Silicon carbide waxa ay leedahay adayg aad u saraysa waxana ay ku saraysaa miisaanka adag ee Mohs, taas oo ka dhigaysa ulaha carbide silikon in ay leeyihiin iska caabin adag oo xidhidh mana fududa in la xidho oo la xoqo. Isla markaana waxa ay leedahay cudud adag iyo cudud xoog leh, waxaanay u adkaysan kartaa xoogag waaweyn oo dibadda ah iyada oo aan jab iyo dhaawac toona lahayn.

Bar dhalaalaysa oo sarreeya iyo iska caabbinta heerkulka sare: Silicon carbide waxay leedahay meel dhalaalaysa oo aad u saraysa, oo inta badan ka saraysa 2700 ℃, taas oo u sahlaysa ulaha silikoon carbide si ay u ilaaliso waxqabadka degan ee jawiga heerkulka sare. Heerkulka caadiga ah ee shaqada wuxuu gaari karaa ilaa 1450 ℃, waxaana si joogto ah loo isticmaali karaa waqti dheer, sida 2000 saacadood jawi oksaydh ah.

Isku xidhka ballaadhinta kulaylka hoose: Kordhinta balaadhinta kulaylkeedu waa mid hooseeya. Marka heerkulku is beddelo, cabbirka usha carbide ee silikoon ayaa isbeddelaysa wax yar. Sidaa darteed, marka lagu isticmaalo heerkulka sare, heerka qallafsanaanta kulaylku waa hooseeyaa, waxayna ilaalin kartaa xasilloonida cabbirka wanaagsan iyo sharafta qaabdhismeedka.

Dhaqdhaqaaqa kulaylka wanaagsan: Ulaha silikoon carbide waxay leeyihiin kororka kulaylka sare, si dhakhso ah u qaban karaan kulaylka, waxay gaari karaan kuleyl degdeg ah, wanaajiya waxtarka kulaylka, iyo sidoo kale ku habboon qaybinta kulaylka isku mid ah.

Iska caabin sare iyo dahaarka korantada: Iyada oo iska caabin ku habboon, waxaa loo isticmaali karaa in lagu soo saaro walxaha kuleyliyaha oo si wax ku ool ah loogu beddelo tamarta korantada tamarta kulaylka. Waxay leedahay wax qabad koronto oo wanaagsan, kaas oo ka ciyaari kara doorka dahaarka ee qalabka korantada si looga hortago dhibaatooyinka sida daadinta hadda iyo wareegyada gaaban.

guryaha Chemical

Degganaanshiyo kiimiko oo sarreeya: Heerkulka qolka, silikoon carbide waxay leedahay xasillooni kiimiko oo wanaagsan inta badan walxaha kiimikaad mana fududa in kiimikaad looga falceliyo asiidh, alkalis, cusbada iyo walxaha kale. Xataa deegaanka heerkulku sareeyo, xasiloonideeda kiimikaad ayaa wali wanaagsan waxayna iska caabin kartaa oksaydhka, daxalka iyo saamaynta kale.

Iska caabbinta oksaydheynta xooggan: Deegaanka hawada sare ee heerkulka sare, filim ilaalin ah oo silikoon oxide cufan ayaa ka samaysan doona dusha sare ee usha silikoon carbide. Filimkan difaaca ayaa ka hortagi kara ogsijiinta in ay sii fal-celiso gudaha gudaha ee carbide silikoon, taas oo siinaya iska caabin oksaydh oo wanaagsan iyo kordhinaysa nolosha adeeggeeda.

Sifooyinka kale

Waxqabadka habaynta wanaagsan: Inkasta oo carbide silicon uu leeyahay engegnaantiisa sare, waxaa laga samayn karaa ulaha qaabab iyo cabbiro kala duwan iyada oo loo marayo technology processing ku habboon si ay u daboolaan baahida xaaladaha codsiga kala duwan, sida dunta, U-qaabeeya, H-qaabeeya, iwm.

Nolosha adeegga muddada dheer: Sababtoo ah caabbinta heerkulka sare, caabbinta oksaydhka, caabbinta daxalka, guryaha wanaagsan ee farsamada iyo xasiloonida kiimikada, ulaha silikoon carbide waxay leeyihiin nolol dheer oo adeeg ah oo hoos yimaada shuruudaha isticmaalka caadiga ah, yaraynta inta jeer ee beddelka iyo yaraynta kharashka isticmaalka.
