Alumina giraanta dhoobada

 

Alumina Ceramic waa alaabta dhoobada farsamada ee aadka loo isticmaalo. Waxay leedahay caabbinta xidhashada sare, xoog farsamo oo sarreeya, iska caabin heerkul sarreeya, caabbinta shoogga kulaylka wanaagsan, dahaarka koronto ee ugu fiican. Inta badan waxaa loo isticmaalaa insulators koronto, xidho qaybo adkaysi u, qaybo dhoobada foornada heerkulka sare iwm Alumina Ceramic waxaa lagu samayn karaa daahiriyo kala duwan sida 95%, 96%, 99%, 99.5%, 99.7% iwm, hantidooda yeelan doonaan wax yar. kala duwanaansho waafaqsan. Warshadaha boodboodka waxay bixiyaan nadiifin kala duwan oo dhoobada ah waxa ku haboon aagga shuruudaha kala duwan.
