Faahfaahinta Badeecada

Calaamadaha Alaabta

Shirkaddayadu waxay bixisaa adeegyada habka dahaarka SiC iyadoo la adeegsanayo habka CVD ee dusha sare ee garaafitka, dhoobada iyo agabyada kale, si gaasaska gaarka ah ee ka kooban kaarboon iyo silikoon ay uga falceliyaan heerkulka sare si ay u helaan molecules-ka SiC ee saafiga ah, molecules-ka lagu shubo dusha sare ee agabka dahaarka leh, iyagoo sameeya lakab ilaalin SIC ah.

 

Astaamaha ugu muhiimsan:

1. Iska caabinta oksaydhka heerkulka sare:

Iska caabbinta oksaydhku wali aad bay u fiican tahay marka heerkulku uu gaaro 1600 C.

2. Nadiifnimo sare: waxaa lagu sameeyaa kaydka uumiga kiimikada iyadoo xaalad koloriin heerkul sare leh.

3. Iska caabbinta nabaad-guurka: adkaansho sare, dusha sare oo is haysta, walxo yaryar.

4. Iska caabbinta daxalka: aashitada, alkali, milixda iyo walxaha dabiiciga ah.

Shahaadooyinka

Su'aalaha Badiya La Weydiiyo

S: Ma shirkad baad ka ganacsataa mise shirkad?
A: Waxaan nahay warshad ka badan 10 sano oo leh shahaadada ISO9001.
S: Waa intee in le'eg waqtiga keenistaadu?
J: Guud ahaan waa 3-5 maalmood haddii alaabtu kaydsan tahay, ama 10-15 maalmood haddii alaabtu aanay kayd ahayn, waa sida aad tiradaada u kala badan tahay.
S: Sideen u heli karaa muunadda si aan u hubiyo tayadaada?
J: Ka dib marka la xaqiijiyo qiimaha, waxaad u baahan kartaa muunado si aad u hubiso tayada alaabtayada. Haddii aad u baahan tahay muunad madhan si aad u hubiso naqshadda iyo tayada, waxaanu ku siin doonaa muunad bilaash ah ilaa inta aad awoodid xamuulka degdegga ah.
S: Waa maxay shuruudaha lacag bixintaada?
J: Waxaan aqbalnaa lacag bixinta Western union, Paypal, Alibaba, T/T, L/C, iwm.. si aad u dalbato lacag badan, waxaan sameynaa dhigaal 30% ah, dheelitirka ka hor inta aan la keenin.
