Dharka Sarreysa ee Alumina Alumina Ceramic Bit Tool
Goobta Codsiga
Qalabka birta dhoobada alumina waxaa si weyn loogu isticmaalaa meelo kala duwan sababtoo ah hantidooda sare.
Marka hore, alumina aaladda yar ee dhoobada waxay si fudud u gooyn kartaa walxo adag oo kala duwan sida dhalooyinka, ceramics, iyo sibidhka sababtoo ah adkaantooda sare iyo xidhashada caabbinta.Intaa waxaa dheer, waxaa loo isticmaali karaa goynta-xawaaraha sare leh iyo farsamaynta, iyo sidoo kale jawiga adag sababtoo ah xasiloonida kulaylka wanaagsan iyo caabbinta kiimikada.
Marka labaad, aaladaha yar ee alumina dhoobada ayaa sidoo kale si ballaaran loogu isticmaalaa dhinacyo kala duwan sida elektiroonigga, kiimikooyinka, iyo wax soo saarka.Tani waa sababta oo ah qalab yar oo dhoobada alumina ah ayaa leh xirmo wanaagsan iyo caabbinta daxalka wanaagsan, waxay si wax ku ool ah u gooyn kartaa qaybaha kala duwan ee elektiroonigga ah iyo wareegyada, waxayna sidoo kale aad ugu habboon yihiin jarida alaabta ceeriin ee kiimikada.
Intaa waxaa dheer, qalab yar dhoobada alumina waxaa loo isticmaali karaa si ay u soo saaraan qalab warshadeed kala duwan sida giraangiraha shiidi, balliyada kubada, iwm Alaabooyinkan ayaa weli sii hayn kara waxqabadka fiican ee jawi adag sida heerkulka sare, cadaadis sare, iyo daxalka.
Ugu dambeyntiina, qalabka birta dhoobada alumina ayaa sidoo kale loo isticmaali karaa goobta caafimaadka, sida soo saarista lafaha macmalka ah, kala-goysyada, iwm. Alaabooyinkani waxay u baahan yihiin heer sare oo biocompatibility iyo xasilloonida muddada dheer, taas oo mindiyaha dhoobada alumina la kulmi karo.
Guud ahaan, qalabka birta dhoobada alumina waxay leedahay codsiyo kala duwan oo kala duwan waxayna dabooli karaan baahiyaha goobo kala duwan.
