Aluminum sulfate
Gabatarwa na Aluminum sulfate
Aluminum sulfate gishiri ne tare da dabarar Al2 (SO4) 3. Yana da narkewa a cikin ruwa kuma ana amfani da shi a matsayin wakili na coagulating a cikin tsarkakewar ruwan sha da masana'antun sarrafa ruwa, da kuma masana'antar takarda. Mu Aluminum Sulfate yana da foda granules, flakes, da Allunan, mu kuma iya samar da babu-ferric, low-ferric, da kuma masana'antu sa.
Aluminum sulfate ya wanzu azaman fari, lustrous crystals, granules, ko foda. A cikin yanayi, yana wanzu a matsayin ma'adinai alunogenite. Aluminum sulfate wani lokaci ana kiransa alum ko alum mai yin takarda.
