Giraanta dhoobada ee Zirconia
Sharaxaada Alaabta:
Shirkaddu waxay qaadataa tignoolajiyada casriga ah ee dhoobada adduunka iyo habka hadafka hal-abuurka, waxay qabataa qalab xirfadeed iyo qalab tijaabo ah, waxay si adag u xakameysaa tayada badeecada, waxayna siisaa Y-ZR, A-ZR, FZTA iyo carbide silicon iyo xoog kale oo sarreeya, xirto caabbinta, iska caabin daxalka, heerkulka sare iska caabin injineernimada qaybo dhoobada in ay gudaha iyo dibadda markets.Among iyaga ka mid ah, A-ZR dhoobada dhoobada waxaa si ballaaran loo isticmaalaa in beeraha kala duwan ee warshadaha leh ay qiimo fiican oo tayo leh oo tayo leh.
Iyada oo awooddeena wax-soo-saarka iyada oo loo marayo mashiinnada shiididda saxda ah, waxaan awoodnaa inaan bixinno qaybo badan oo kala duwan oo sax ah oo zirconia ah si loo daboolo baahida macaamiisha saxda ah ee sare.
Astaamaha ugu muhiimsan:
1) Xoog sare;
2) U adkaysta daxalka;
3) caabbinta xirashada sare, dufan wanaagsan oo nafsi ah.
Goobaha codsiga:
Ku habboon xudunta udub-dhexaadka, caaryada, qalabka goynta, xajinta, shafka, giraanta xidhidhiyaha, xargaha, iwm.
