Aluminum sulfate is an extremely versatile basic chemical raw material, playing a key role in various industrial fields. It is not only a cornerstone material in the traditional paper-making and water treatment industries but also widely used in sectors like dyeing, leather, cosmetics, construction, and food processing. With its excellent flocculation, precipitation, color fixing, and cross-linking abilities, aluminum sulfate bulk has become the preferred choice for bulk procurement by many companies.
In the paper-making industry, aluminum sulfate is primarily used as a paper sizing agent. It reacts with rosin or wax emulsion to form water-insoluble adhesives, significantly enhancing the water resistance and permeability of the paper, making it more suitable for writing or printing. Additionally, aluminum sulfate serves as an indispensable high-efficiency flocculant in drinking water and industrial wastewater treatment. Once added, it quickly forms aluminum hydroxide flocs, effectively adsorbing bacteria, colloids, and suspended impurities in the water, helping to remove color, odor, and improve water quality. This characteristic makes it a bulk procurement item for various water utilities and environmental companies, with aluminum sulfate bulk provided by aluminum sulfate supplier being particularly suitable for large-scale water treatment systems due to its cost-effectiveness.
Aluminum sulfate is also extensively used in various fine chemical and industrial processes. For example, in the dye industry, it is an important precipitating agent in the manufacture of chrome yellow and lakes, also providing excellent color fixing and filling properties. In the firefighting field, it can be combined with baking soda and foaming agents to form foam fire extinguishing agents, used for the rapid extinguishment of oil fires.
Moreover, aluminum sulfate is an effective cross-linking agent, commonly used to enhance the properties of animal glue and urea-formaldehyde adhesives. Its 20% aqueous solution has a fast curing capability, widely applied in the furniture, construction, and board industries. In the food industry, specially treated aluminum sulfate can be used as a stabilizer for pasteurized liquid egg products, meeting food safety standards. In the cosmetics field, it is commonly used as an ingredient in antiperspirants due to its good astringent properties.
In addition to its key uses mentioned above, aluminum sulfate can also be used to manufacture artificial gemstones, refine alum (such as ammonium alum, potassium alum), petroleum decolorizing agents, concrete waterproofing agents, and catalyst carriers. Bulk aluminum sulfate is convenient to transport and low in cost, especially suitable for companies requiring large quantities of continuous supply, such as water utilities, paper mills, chemical companies, and concrete admixture manufacturers. To ensure safe transportation and storage, it is recommended to store aluminum sulfate bulk in a cool, dry place, avoiding direct sunlight and humid environments.
