Maareynteena weyn, awood farsamo oo awood leh iyo habraac adag oo adag, waxaan sii wadeynaa inaan siino macaamiisheena tayada sare ee sumcadda leh, qiimaha iibka macquulka ah iyo bixiyeyaasha waaweyn. Waxaanu ujeedadiisu tahay inaanu ka mid noqono la-hawlgalayaasha aadka aad ugu kalsoon tahay oo aanu kasbano qanacsanaantaada Wanaagsan Iibiyeyaasha Jumlada Wanaagsan ee Shiineeska Abrasive Polishing and Sandblasting Silicon Carbide NanoSidaHabdhaqanka kulaylka Wanaagsan, Hadafkayaga kama dambaysta ahi waa had iyo jeer in aan ku darajeyno sidii sumad sare iyo sidoo kale in aan horseedno hormood ahaan beertayada. Waxaan hubnaa in waayo-aragnimadeena wax-soo-saarka leh ee abuurista aaladaha ay heli doonto kalsoonida macaamiisha, Waxaan rabnaa inaan iskaashi iyo wada-abuurno adiga muddo dheer ka sii wanaagsan!

Haddii aad xiisaynayso mid ka mid ah badeecadayada ama aad jeceshahay inaad ka hadasho dalabka gaarka ah, fadlan xor u noqo inaad nala soo xidhiidho. Waxa aanu rajaynaynaa in aanu mustaqbalka dhaw la samayno xidhiidh ganacsi oo guulaysta macaamiisha cusub ee aduunka.
Sharaxaada Alaabta
Shirkadeena waxay bixisaa adeegyada habka daahan SiC ee habka CVD ee dusha sare ee graphite, ceramics iyo alaabta kale, si gaasaska gaarka ah ee ay ku jiraan kaarboon iyo silikoon ay uga falceliyaan heerkulka sare si ay u helaan nadiifnimada sare ee SiC molecules, molecules deposited on the dusha alaabta dahaarka ah, samaynta lakabka ilaalinta SIC.
Tilmaamaha ugu muhiimsan:
1. Iska caabbinta oksaydhka heerkulka sare:
caabbinta oksaydhisku weli aad bay u wanaagsan tahay marka heerkulku gaadho 1600 C.
2. Nadiifin sare: oo ay samaysay uumiga kiimikaad ee hoos yimaada xaalad koloriineed heerkul sare ah.
3. Iska caabinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
