Our product, High Quality Aluminium sulfate CAS 10043-01-3 With Low Price, is a chemical compound widely used in various industries. Its chemical formula is Al₂(SO₄)₃. Aluminium sulfate usually exists in the form of hydrates, with the most common being the octadecahydrate Al₂(SO₄)₃·18H₂O.
The appearance of this product is a white crystalline powder or granules. It has good solubility in water, and its aqueous solution is acidic due to the hydrolysis of aluminium ions. The product has a high degree of purity, ensuring its effectiveness in different applications.
Aluminium sulfate with CAS number 10043 - 01 - 3 is produced under strict quality control measures. The specific gravity of the product is approximately 1.69 g/cm³. It has a melting point of around 770°C (decomposes). These parameters make it suitable for a variety of processes.
1. Water Treatment: Aluminium sulfate is a commonly used coagulant in water treatment plants. It can effectively remove suspended solids, colloids, and some organic matter from water. When added to water, it forms aluminium hydroxide flocs, which can trap impurities and settle them at the bottom, thus purifying the water.
2. Paper Industry: In the paper - making process, it is used as a sizing agent. It helps to improve the paper's strength, water resistance, and ink absorption properties. By adjusting the amount of aluminium sulfate added, the quality of the paper can be controlled.
3. Textile Industry: Aluminium sulfate is used in textile dyeing and printing. It can act as a mordant, which helps dyes to bind more firmly to the fabric, improving the color fastness of the dyed products.
4. Leather Tanning: It is also used in the leather industry to remove lime from the hides during the tanning process. This helps to prepare the hides for further processing.
1. Water Treatment: The dosage of aluminium sulfate in water treatment depends on the quality of the raw water. Generally, it is added in the range of 10 - 100 mg/L. First, dissolve the appropriate amount of aluminium sulfate in water to form a solution, and then add it to the water to be treated. Stir the water well to ensure uniform mixing. After a certain period of sedimentation, the clarified water can be further processed.
2. Paper Industry: In paper production, the addition amount of aluminium sulfate is usually determined according to the type of paper and the production process. It is typically added to the pulp at a concentration of 0.5 - 2% (based on the dry weight of the pulp). Mix it thoroughly with the pulp to achieve the desired sizing effect.
3. Textile Industry: As a mordant, aluminium sulfate is dissolved in water to form a solution with a concentration of about 1 - 5%. The fabric is then immersed in this solution for a certain period, usually 30 minutes to 2 hours, depending on the type of fabric and dye. After that, the fabric is taken out, rinsed, and then dyed.
4. Leather Tanning: When used in leather tanning, the hides are soaked in a solution containing aluminium sulfate with a concentration of about 2 - 5%. The soaking time is usually several hours to ensure complete removal of lime from the hides.
1. Water Treatment Case: A small - scale water treatment plant in a rural area was facing problems with high turbidity in the raw water. After using our aluminium sulfate, they added it at a dosage of 30 mg/L. The turbidity of the water decreased significantly within 2 hours of sedimentation. The treated water met the local drinking water standards, and the plant was able to provide clean water to the local community more effectively.
2. Paper Industry Case: A paper mill wanted to improve the water - resistance of their packaging paper. By adjusting the amount of aluminium sulfate added to the pulp to 1.5%, they found that the paper's water - resistance increased by 30%. This improvement made the packaging paper more suitable for protecting products during transportation.
3. Textile Industry Case: A textile factory was having issues with poor color fastness of their dyed fabrics.
