Aluminium Sulphate Production Equipment Supplier

Product Introduction of Aluminum Sulfate

一、 Basic Product Information
Aluminum Sulfate (chemical formula: Al₂(SO₄)₃, with the common crystalline hydrate being octadecahydrate aluminum sulfate Al₂(SO₄)₃·18H₂O) is a basic inorganic aluminum salt chemical product with stable performance and wide applications. It appears as white flaky, granular or powdery solid, is readily soluble in water, and its aqueous solution is weakly acidic. It possesses core properties such as flocculation, precipitation, sizing, mordanting, and corrosion inhibition.

The product strictly complies with national and industrial quality standards, with strict control over impurities such as iron and heavy metals. It is available in industrial grade, low-iron grade, iron-free grade and other specifications, featuring high purity, good solubility, high utilization efficiency and strong stability. It can meet high-standard application requirements including drinking water purification, high-grade papermaking, and fine chemical engineering.

二、Core Application Fields
1. Water Treatment (Core Application)
As a classic and high-efficiency inorganic flocculant, it hydrolyzes into aluminum hydroxide colloid after dissolving in water, which strongly adsorbs suspended solids, colloids, bacteria and heavy metal ions to achieve water purification.
Drinking Water Purification: Iron-free grade is suitable for water plants, removing turbidity and odor to meet drinking water standards;
①Industrial Wastewater Treatment: Treats wastewater from printing and dyeing, chemical, papermaking and mining industries, reducing COD, removing chroma and suspended solids;
②Urban Sewage Treatment: Accelerates sludge sedimentation, improves solid-liquid separation efficiency and reduces treatment costs.

2. Papermaking Industry (Key Application)
Used as paper sizing agent, precipitant and filler fixing agent to improve paper quality.
①Enhances water resistance, impermeability, hardness, smoothness and stiffness, optimizing printing performance;
②Reduces paper linting and dusting, facilitating uniform adhesion of sizing materials;
③Iron-free grade is used for high-grade cultural paper and packaging paper to prevent yellowing and discoloration, ensuring whiteness.

3. Textile Printing and Dyeing
Used as a mordant, color fixing agent and anti-bleeding agent, helping dyes adhere firmly to fibers, improving dyeing uniformity and color fastness, preventing color bleeding and cross-staining, and enhancing fabric hand feel and luster.

4. Leather Tanning
As a leather tanning agent, it cross-links with leather fibers to improve flexibility, durability and wear resistance, reduce shrinkage and cracking, extend the service life of leather, and is suitable for the processing of light leather and heavy leather.

5. Other Applications
①Fire Fighting: Core raw material for foam fire extinguishing agents, compounded to produce high-efficiency fire-extinguishing foam;
②Fine Chemical Engineering: Prepares aluminum salts such as aluminum hydroxide, aluminum chloride and alum, used as raw materials for oil clarification, wood preservation and cosmetic astringents;
③Building Materials: Ingredient for refractory materials and concrete additives, improving strength and high-temperature resistance;
④Agriculture: Improves acidic soil, used as a pesticide adjuvant to enhance adhesion and permeability of agents.

三、Production Process and Quality Assurance
Adopting advanced acid hydrolysis continuous process + automatic control system, with refined management and control throughout the whole process:
