Budada Alumina ee Calcined Platelet
Budada dhalaalinta ee loo yaqaan 'Plate Calcined Alumina' waxaa laga sameeyay budada warshadeed ee tayo sare leh ee alumina sida walxo ceeriin ah, waxaana lagu farsameeyaa hab wax soo saar gaar ah. Qaabka kiristaalka ee budada dhalaalinta alumina ee la soo saaray waa qaab shaxeed siman oo u eg shax, sidaas darteed waxaa loo yaqaan Platelet Alumina ama Table Alumina.
Platelet Alumina waa budo tayo sare leh oo alumina ah, oo ka kooban kiristaal u eg saxan oo Al2O3 ah oo leh nadiifnimo ka badan 99.0%. Waxay leedahay sifooyin aad u fiican oo u adkaysta kulaylka iyo sidoo kale kiimiko ahaan aan firfircoonayn, mana mirqaansana asiidhyada ama alkalines. Maadaama qaybinta cabbirka walxaha ee Platelet Alumina si adag loo xakameeyey, waxay soo saari kartaa dusha sare oo aad u fiican, taasoo siinaysa waxtar aad u sarreeya oo ah xoqid. Iyada oo leh noocyo badan oo isticmaal ah, Platelet Alumina waa budo xoqid ah oo awood u leh inay qabato hawlo badan.

Faa'iidooyinka Budada Alumina
1. Isbarbardhig budada kale ee shaxda, budada alumina ee shaxda leh waxay leedahay sifooyin isku-dhafan oo heer sare ah. Sida dhibic dhalaal badan, adkeysi xooggan, xoog farsamo oo sare, iska caabin wanaagsan oo xirasho, iska caabin kiimiko, iska caabin oksaydh iyo iska caabin kulayl iwm.
2. Qaabka xaashida fidsan ayaa ka dhigaya is jiidjiid weyn, waxay wanaajisaa xawaaraha shiididda iyo hufnaanta, tani waxay yareyn kartaa tirada mashiinnada shiididda, shaqada iyo waqtiga shiididda.
3. Qaabka xaashida fidsan waxay ka dhigaysaa in shiididda shayga aan si fudud loo xoqin, heerka badeecadaha u qalma ayaa kordhi kara 10%-15%. Tusaale ahaan, heerka wafer silicon semiconductor-ka u qalma wuxuu gaari karaa 96% ama ka badan.
4. Waxay leedahay saameyn labanlaab ah oo ah budada nano iyo kuwa yaryar, dhaqdhaqaaqa dusha sare waa mid dhexdhexaad ah, ma aha oo kaliya inuu si wax ku ool ah ula midoobi karo kooxaha kale ee firfircoon, laakiin sidoo kale ma fududa in la isku ururiyo oo la fududeeyo kala firdhinta waxtarka leh.
5. Waxay leedahay dhegdheg wanaagsan, saameyn difaac oo muhiim ah iyo awood ay ku iftiimiso iftiinka.
6. Budada alumina ee shaxda ku taal waa mid hufan, midab la'aan ah, waxayna leedahay dusha siman oo siman. Kiristarrada si fiican loo sameeyay waa lixgeesle caadi ah.
7. Budada alumina ee shaxda leh waxaa laga samayn karaa budo dhalaalineed oo aad u fiican.
1. Warshadaha elektaroonigga ah: shiididda iyo dhalaalinta wafers-ka silikoon ee semiconductor-ka ah ee monocrystalline, kiristaalo quartz quartz ah, semiconductors-ka isku dhafan (gallium crystalline, nano phosphating).
2. Warshadaha galaaska: shiididda iyo farsamaynta galaaska kiristaalka, galaaska quartz, shaashadda qolofta galaaska kinescope, galaaska indhaha, muraayadda muraayadda dareeraha ah (LCD), iyo galaaska quartz.
3. Warshadaha dahaarka: dahaarka gaarka ah iyo buuxinta buufinta plasma.
4. Warshadaha wax soo saarka birta iyo dhoobada: agabka dhoobada saxda ah, agabka ceeriin ee dhoobada lagu sifeeyay, dahaarka heerkulka sare ee heerka sare ah, iwm.
