Waxaan leenahay kooxdayada iibka, kooxda naqshadeynta, kooxda farsamada, kooxda QC iyo kooxda xirmo. Waxaan leenahay nidaamyo adag oo lagu xakameynayo tayada habraac kasta. Sidoo kale, dhammaan shaqaalahayagu waxay khibrad u leeyihiin goobta daabacaadda ee qiimaha la soo xigtay ee Shiinaha Celinta Heerkulka Sare ee Cagaaran Silicon Carbide Abrasive Powder Black Silicon Carbide Polishing Powder, faa'iidada macaamiisha iyo qanacsanaanta ayaa caadiyan ah ujeedkayaga ugu weyn. Xusuusnow inaad nala soo xiriirto. Na sii ixtimaalka, ku siiya wax lala yaabo.

Sidoo kale, dhammaan shaqaalahayagu waxay khibrad u leeyihiin goobta daabacaadaShiinaha Silicon Carbide, SidaWaa maxay qiimaha wanaagsan? Waxaan siinaa macaamiisha qiimaha warshadda. Marka la eego tayada wanaagsan, waxtarka waa in fiiro gaar ah loo yeesho oo la ilaaliyo faa'iidooyinka hooseeya iyo kuwa caafimaad qaba. Waa maxay dhalmada degdega ah? Waxaan u samaynaa gaarsiinta si waafaqsan shuruudaha macaamiisha. In kasta oo wakhtiga keenista ay ku xidhan tahay tirada dalabka iyo kakanaanta ay leedahay, waxaan wali isku daynaa in aan keeno badeecadaha iyo xalalka wakhtiga. Waxaan si dhab ah u rajaynaynaa inaan yeelan karno xidhiidh ganacsi oo wakhti dheer ah.
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.
