Hydrated aluminum sulfate is a white flaky or powdery substance. It is highly soluble in water, almost insoluble in ethanol, and its solution is acidic. Upon prolonged boiling, insoluble basic salt precipitates may form.<\/p>\n\n\n\n

Hydrated aluminum sulfate containing low-valence iron salts often has a light green color; low-valence iron salts are prone to oxidation, which can also cause the surface of hydrated aluminum sulfate to turn yellow.<\/p>\n\n\n\n

We provide high-quality iron-free hydrated aluminum sulfate products with a 17% Aluminum oxide (Al\u2082O\u2083).<\/p>\n\n\n\n

\u200bMain Application Fields<\/strong><\/p>\n\n\n\n

Chemical industry and water treatment, including use as a flocculant and water purifying agent; in the paper industry as a sizing agent; and in building materials as an accelerating agent.<\/p>\n\n\n\n

For applications such as papermaking, it is recommended to use high-quality white iron-free aluminum sulfate. For municipal water treatment and similar fields, there are limits on the content of heavy metal ions in the product.<\/p>\n\n\n\n

\u200bApplications<\/strong>\u200b<\/p>\n\n\n\n

    \n
  • \u200bIn the paper industry:\u200b<\/strong>\u200b Used as a precipitant for rosin glue, wax emulsion, and other sizing agents to enhance the water resistance and anti-permeability of paper. It is also used in the flocculation treatment of papermaking wastewater to reduce COD and suspended solids.<\/li>\n\n\n\n
  • \u200bIn the water treatment industry:\u200b<\/strong>\u200b Hydrated aluminum sulfate is a commonly used inorganic flocculant. It generates aluminum hydroxide colloids through hydrolysis to adsorb suspended solids in water, and is widely used in drinking water, industrial wastewater, and sewage treatment.<\/li>\n\n\n\n
  • \u200bIn wastewater treatment:\u200b<\/strong>\u200b Used as a raw material for deep defluorination agents and phosphorus removal chemicals.<\/li>\n\n\n\n
  • \u200bIn the dyeing and printing industry:\u200b<\/strong>\u200b Used as a mordant and an anti-bleeding agent for printing.<\/li>\n\n\n\n
  • \u200bIn the fats and oils industry:\u200b<\/strong>\u200b Used as a clarifying agent.<\/li>\n\n\n\n
  • \u200bIn the petroleum industry:\u200b<\/strong>\u200b Used as a decolorizing and deodorizing agent.<\/li>\n\n\n\n
  • \u200bIn the wood industry:\u200b<\/strong>\u200b Used as a preservative.<\/li>\n\n\n\n
  • \u200bIn firefighting:\u200b<\/strong>\u200b Often combined with baking soda and foaming agents to make foam-type fire extinguishing agents.<\/li>\n\n\n\n
  • \u200bIn the dye industry:\u200b<\/strong>\u200b Used as a mordant and fixing agent.<\/li>\n\n\n\n
  • \u200bIn medicine or cosmetics:\u200b<\/strong>\u200b Used as an astringent (e.g., antiperspirant).<\/li>\n\n\n\n
  • \u200bIn the construction industry:\u200b<\/strong>\u200b Used as a concrete accelerating agent.<\/li>\n\n\n\n
  • \u200bAs a raw material for aluminate:\u200b<\/strong>\u200b Used in the preparation of alumina ceramics and refractory bricks.<\/li>\n<\/ul>\n\n\n\n

    \u200bPackaging:\u200b<\/strong>\u200b Polyethylene plastic woven bags. Each bag contains 50 kg, available in ton bags or customized packaging according to customer requirements.<\/p>\n\n\n\n

    \u200bStorage and Transportation:\u200b<\/strong>\u200b Store in a cool, shaded, dry, and ventilated warehouse. Keep away from moisture. Do not store or transport together with toxic substances or alkaline materials.<\/p>\n\n\n\n
