Alumina Sheets Ceramic Sheets & Tansparent Alumina Plate: Qalabka Waxqabadka Sare ee Codsiyada Saxda ah ee alumina xaashida dhoobada alumina iyo taarikada dhoobada alumina waa dhoobada farsamaysan ee horumarsan oo caan ku ah adkeysigooda gaarka ah, xasiloonida kulaylka, iyo guryaha dahaarka korantada. Waxqabadku maaha mid ka hooseeya kan ceramics Zirconia. Kuwani xaashida dhoobada alumina ee saxda ah ayaa laga sameeyay aluminium saafi ah, taas oo ka dhigaysa mid aad ugu habboon codsiyada warshadaha iyo injineernimada ee kala duwan. Haddii aad u baahan tahay qayb daaha ka sameysan, dusha xirashada u adkeysaneysa, ama shay awood u leh in ay u adkeyso heerkulka aadka u daran, xaashida dhoobada alumina iyo taarikada ayaa ku siin kara xalal lagu kalsoonaan karo. Awoodooda farsamo ee gaarka ah iyo iska caabbinta kiimikaad ayaa ka dhigaya alaabtan in si weyn loogu qiimeeyo qalabka elektiroonigga ah, baabuurta, hawada hawada, iyo qaybaha qalabka caafimaadka. Goobta elektiroonigga ah, xaashida dhoobada alumina ayaa loo isticmaalaa sida substrate-ka wareegyada isku dhafan, oo leh kuleyl heer sare ah iyo dahaarka korantada. Awooddooda lagu ilaaliyo xasilloonida cabbirka heerkulka sare waxay hubisaa waxqabadka muddada-dheer iyo kalsoonida. Waraaqaha dhoobada ah ee alumina ee saxda ah ayaa caadi ahaan loo isticmaalaa soo saarista qaybaha muhiimka ah sida dareemayaasha iyo capacitors sababtoo ah qaybahani waxay u baahan yihiin saxnaan sare iyo adkeysi. Mid ka mid ah faa'iidooyinka muhiimka ah ee xaashida dhoobada alumina waa porosity hooseeya iyo cufnaanta sare, taas oo u oggolaanaysa inay yeeshaan sifooyin farsamo iyo kulayl aad u fiican. Tani waxay ka dhigaysaa inay ku habboon yihiin codsiyada inta badan la kulma kiimikooyin xooggan ama deegaan heerkul aad u daran. Intaa waxaa dheer, dabeecadda aan fiicnayn ee xaashida dhoobada alumina ayaa ka dhigaysa doorasho ku habboon codsiyada dahaarka korantada. Habka wax-soo-saarku waxa uu ku lug leeyahay sifaynta budada alumina ee nadiifka ah ee heerkul aad u sarreeya si loo sameeyo qaab-dhismeed cufan oo isku mid ah. Nidaamkani wuxuu hubinayaa in badeecada ugu dambeysa aysan lahayn wax cillad ah oo ay ilaaliso tayada joogtada ah dhammaan cutubyada. Sidaa darteed, xaashiyaha dhoobada ah waxaa si weyn loogu isticmaalaa codsiyada injineernimada saxda ah sababtoo ah xitaa kala duwanaansho yar ayaa yeelan kara saameyn weyn. Isticmaalka xaashida dhoobada alumina waxay dhaafsiisan tahay warshadaha dhaqanka. Waxa kale oo loo isticmaalaa qalabka shaybaadhka, sida weelasha iyo weelasha falcelinta, taas oo ay ugu wacan tahay awoodda ay u leeyihiin in ay iska caabiyaan daxalka kiimikada. Dhinaca caafimaadka, waxaa loo adeegsadaa qalab-ku-jiidhiyaha iyo qalabka qalliinka, iyagoo ka faa'iideysanaya nooleyaalkooda iyo xirashada caabbinta. Markaad dooranayso xaashida dhoobada alumina ama taarikada, arrimaha sida dhumucda, cabbirka, iyo dhamaystirka dusha sare ayaa loo baahan yahay in la tixgeliyo. Tilmaamahaan waxaa lagu habeyn karaa iyadoo loo eegayo shuruudaha gaarka ah ee codsiyada kala duwan. Haddii aad u baahan tahay badeecooyin caadi ah ama xalal habaysan, wax-soo-saarayaashu waxay bixiyaan fursado kala duwan si ay u daboolaan baahiyo kala duwan. Maaddaama warshaduhu ay raadiyaan agab ka shaqeyn kara xaalado adag, baahida loo qabo xaashida dhoobada alumina ee tayada sare leh ayaa sii socota inay koraan.
