    Application

    1 Construction industry

    Early strength agent

    It plays the role of "early strength agent" in concrete admixtures, that is to say, adding an appropriate amount of alum can shorten the time for the concrete to harden to a certain strength.

    Waterproofing agent

    The role of the waterproofing agent is actually to fill the gap of concrete so that the concrete can achieve the purpose of waterproofing, alum has the effect of waterproofing.

    2 Clean water and sewage treatment

    Alum is a common flocculant that can be used to purify water sources and treat sewage. In water purification, alum can be combined with suspended matter and impurities in water into larger clumps, so as to facilitate settlement and filtration, in sewage treatment, alum can effectively remove suspended matter and organic matter in wastewater, improve the treatment effect of wastewater.

    3 Papermaking

    Alum is widely used in the slurry treatment of paper manufacturing. Alum reacts with impurities in the pulp and precipitates to improve the clarity of the pulp and the quality of the paper. At the same time, alum also helps to improve the brightness and light of paper

    4 Leather industry

    Alum has important applications in the leather industry. During the tanning process, alum can regulate the pH of the leather and help the proteins in the leather to solidify and fix, thus increasing the strength and softness of the leather. In addition, it can also improve the dyeing properties of leather and prevent leather corruption.

    5 Printing and dyeing industry

    Alum is an important dye fixative and is widely used in textile and printing industry. It can form a stable complex with the dye, increasing the adhesion and durability of the dye. Alum can also improve the brightness and color fastness of the dye.

    6 Mining and metallurgical industry

    In the mining and metallurgical industry, alum is often used as a mineral processing and flotation agent. Alum can react with the impurities on the ore surface and form a precipitate with the ore, thereby improving the purity and recovery of the ore.

    7 Catering industry

    Alum is widely used in food processing and cooking processes in the catering industry. It can improve the texture and color of food and increase the freshness of food. In cooking, alum can be used to tenderize meat and remove the odor. However, it should be noted that the use of alum should be controlled within a safe dose range to avoid adverse effects on human health.

    8 Cosmetics and personal care products

    Because alum has astringent and antibacterial properties, "it is often added to cosmetics and personal care products. Alum can close the pores and control the oil secretion of the skin, thereby improving the smoothness and fineness of the skin.

    9 Preservatives and lawn treatment

    Alum has antibacterial and antibacterial effects, so it is widely used in preservatives and lawn treatments. It can prevent wood decay and lawn weed growth, and maintain the performance and beauty of building materials and lawns.

    10 Other uses

    Alum has some other uses. For example, alum can be used in the production of gypsum products, in the preparation of glazes and pigments in the ceramic industry, and the preparation of chemical raw materials such as metal salts and alumina.

    In short, alum, as a common inorganic compound, has a wide range of applications. It plays an important role in water and sewage treatment, paper manufacturing, leather and printing and dyeing industry, mining and metallurgy industry, catering industry, cosmetics, and personal care products. Through reasonable application, alum can improve the quality and performance of products, improve production efficiency, and meet people's various needs. However, attention should be paid to the correct use method and dosage of alum to ensure its safety and environmental friendliness.
