The Function And Application Of Iron Free Aluminum Sulfate

In the paper industry, it is used as the precipitator of rosin size, wax lotion and other sizing materials, as the flocculant in water treatment, as well as as the retention agent of foam fire extinguishers, raw materials for manufacturing alum and aluminum white, as well as raw materials for oil decolorization, deodorant and some drugs. It can also manufacture artificial gemstones and high-grade ammonium alum. Products with arsenic content not exceeding 5mg/kg can be used as water treatment flocculants.
1. Used as a paper sizing agent in the papermaking industry to enhance the water resistance and anti-seepage performance of paper;
2. After being dissolved in water, it can cause small particles and natural gel particles in the water to condense into large flocculents, which can be removed from the water. Therefore, it is used as a coagulant for water supply and wastewater
3. Used as a turbid water purification agent, as well as a precipitant, color fixing agent, filling agent, etc. Used as an anti sweat cosmetic ingredient (astringent) in cosmetics;
4. In the fire protection industry, foam extinguishing agent is composed of baking soda and foaming agent;
5. Analytical reagents, mordants, tanning agents, oil decolorizing agents, wood preservatives;
6. Stabilizers for albumin pasteurization (including liquid or frozen whole eggs, protein or egg yolks);
7. Can be used as raw materials for manufacturing artificial gemstones, high-grade ammonium alum, and other aluminates;
In the fuel industry, it serves as a precipitant in the production of chrome yellow and lake dyes, while also serving as a fixing and filling agent.
Iron free aluminum sulfate can be used in the production of high-grade paper, high-grade fabrics, food foaming agents, white rubber, white leather, and other products. At present, the annual production capacity of iron free aluminum sulfate in China is about 1500t, accounting for only 0.19/6-0.2 of the total production of aluminum sulfate
