Sidee loo hagaajiyaa iska caabbinta saameynta ee dahaarka dhoobada ee u adkaysta xirashada?

Xiro dahaarka dhoobada ee u adkaystaxalli dhibaatada xirashada warshadaha xirashada culus sida sibidhka, birta, macdan qodista, baytariyada lithium, iyo birta. Si kastaba ha ahaatee, isticmaalka dhabta ah, warshadaha qaar ayaa aaminsan in dahaarka dhoobada ee xirashada u adkaysta ay yihiin kuwo jilicsan oo aan saameyn u adkaysta. Haddaba sideen u horumarin karnaa iska caabbinta saameynta dahaarka dhoobada ee xirashada u adkaysta?

Maaddada ugu weyn ee dahaarka dhoobada ah ee aan inta badan tixraacno waa alumina, oo ah adkaysi jab oo KΙC ≥4.8MPa•m1/2 iyo xoogga foorarsiga ≥290MPa. Marka la barbardhigo agabka birta sida birta, iska caabbinta saameynta runtii way liidataa, laakiin iyada oo loo marayo habab gaar ah, iska caabbinta saameynta ee dahaarka dhoobada ah ee u adkaysta xirashada si weyn ayaa loo hagaajin karaa.

1. Naqshadeynta dusha sare ee soo-baxa wareegsan:

Sifooyinka farsamada ee gaarka ah ee soo baxa wareega ayaa si siman u kala firdhin kara xoogga saameynta ee dahaarka, taasoo yaraynaysa suurtagalnimada in dahaarka uu jabo saameyn. Waa hab caadi ah oo lagu hagaajiyo iska caabbinta saameynta ee dahaarka dhoobada ah ee u adkaysta xirashada.

2 Kordhi aagga dusha sare ee caagga: Dahaarka dhoobada ee u adkaysta xirashada waxaa inta badan loo isticmaalaa iyadoo lala kaashanayo caagga. Iska caabbinta saameynta ee dhoobada waa mid daciif ah, laakiin iska caabbinta saameynta ee caaggu aad ayuu u xoog badan yahay. Waxaan si buuxda u siin karnaa faa'iidooyinka labadaba, iyadoo la adeegsanayo dhoobada si looga hortago xirashada iyo caagga si looga hortago saameynta. Habka gaarka ah ee hawlgalka waa in lagu soo bandhigo caag badan dusha sare ee dahaarka inta lagu jiro habka vulcanization, sida ka tagista meelaha banaan ama isticmaalka qaybo dhoobo wareegsan. Waa in la ogaadaa in marka aagga caagga ah ee dusha sare ee dahaarka uu kordho, aagga dhoobada ayaa hoos u dhici doona. Iyadoo iska caabbinta saameynta la hagaajiyo, iska caabbinta xirashada ayaa hoos u dhici doonta. Marka la isticmaalayo, waxaa lagama maarmaan ah in si buuxda loo tixgeliyo iyadoo loo eegayo xaaladaha shaqada ee dhabta ah.

3 Ku dar agab kale oo ceeriin ah alumina si loogu daweeyo adkaanta: Chemshun Ceramics Co., Ltd. waxay ka go'an tahay soo saarista iyo cilmi-baarista iyo horumarinta dhoobada u adkaysata xirashada. Qayb go'an oo ah oxide zirconium ayaa lagu daraa agabka ceeriin ee alumina si loo sameeyo dhoobo adkaysi u leh xirashada alumina, taas oo si weyn u hagaajin karta iska caabbinta saameynta dhoobada u adkaysata xirashada. Iska caabbinta saameynta dhoobada alumina u adkaysata xirashada runtii waa mid daciif ah, laakiin dhibaatadan waxaa lagu xallin karaa naqshad wareegsan, caag vulcanized ah, iyo ku darista zirconium oxide, si dahaarka dhoobada u adkaysata xirashada ay ula qabsan karaan inta badan xirashada culus iyo xaaladaha saameynta xooggan.
