Dhexdhexaadinta qarxinta ugu adag ee Silicon Carbide Grit
Sharaxaada Alaabta
Junda Silicon Carbide Grit waa warbaahinta qaraxyada ugu adag ee la heli karo.Alaabtan tayada sare leh waxaa loo soo saaray qaab hadhuudh ah oo blocky ah.Warbaahintan ayaa si joogto ah u burburin doonta taasoo keenaysa geeso fiiqan, gooyn.Adkeysiga Silicon Carbide Grit wuxuu u oggolaanayaa waqtiyo gaaban oo qarax marka loo eego warbaahinta jilicsan.
Sababo la xiriira sifooyinka kiimikaad ee deggan, kuleylka kuleylka sarreeya, isugeynta fidinta kulaylka hooseeya, iyo iska caabin wanaagsan, silikoon carbide waxay leedahay adeegsiyo kale oo badan marka laga reebo in loo isticmaalo sida abrasives.Tusaale ahaan, budada carbide silicon waxaa lagu dabaqaa impeller ama dhululubada marawaxadaha biyaha iyadoo loo marayo hab gaar ah.Darbiga gudaha wuxuu wanaajin karaa caabbinta xirashada wuxuuna ku dheerayn karaa noloshiisa adeeg 1 ilaa 2 jeer;Qalabka refractory-sare ee ka samaysan wuxuu leeyahay caabbinta shoogga kulaylka, cabbir yar, miisaan fudud, xoog sare iyo saameyn wanaagsan oo tamar-badbaadin ah.Silicon carbide-ka hooseeya (oo ka kooban 85% ee SiC) waa deoxidizer heersare ah.Waxay dedejin kartaa xawaaraha birta samaynta, waxayna fududayn kartaa xakamaynta isku dhafka kiimikada waxayna hagaajinaysaa tayada birta.Intaa waxaa dheer, silikoon carbide ayaa sidoo kale si ballaaran loo isticmaalaa in lagu sameeyo ulaha silikoon carbide ee walxaha kuleylka korantada.
Silicon carbide waxa uu leeyahay adayg aad u sarreeya, oo leh adayg Mohs ah 9.5, oo ka xigta kaliya dheemanka adduunka ugu adag (10).Waxay leedahay kulaylka kuleylka heer sare ah, waa semiconductor, waxayna iska caabin kartaa oksaydhka heerkulka sare.
