Product Description
Product name: Aluminum Sulfate
Chemical Formula: Al2(SO4)3
Cas: 10043-01-3
Description: Industrial - grade aluminium sulfate, denoted by the chemical formula Al2(SO4)3, commonly contains 14 to 18 water molecules in its crystalline structure. The most prevalent hydrate variant is Al2(SO4)3·18H2O. In its pure state, it exists as a colorless, transparent, block - shaped crystal or a fine crystalline powder. Yet, owing to the inclusion of impurities, its color can deviate, presenting as gray - white, light - yellow, or light - green.
This chemical compound has a high solubility in water, and the resulting aqueous solution exhibits acidic characteristics. When it undergoes hydrolysis, a gelatinous precipitate of aluminium hydroxide is produced.

Application
In the paper - making sector, aluminium sulfate is of great importance as a sizing agent. It can form chemical bonds with the cellulose in paper. This bonding results in the formation of a protective film. This film acts as a deterrent to water absorption by the paper, thus enhancing the paper's water - repellent property.
Moreover, during the papermaking procedure, aluminium sulfate serves as a precipitant. It is utilized to precipitate the impurities and suspended substances that are generated during the manufacturing process. By doing so, it contributes to producing paper that has a whiter appearance and a smoother texture.
Aluminium sulfate is actively involved in the leather tanning process. It forms a chemical union with the collagen fibers in leather. This interaction causes the leather's structure to become more closely packed, which in turn makes the leather more durable and less prone to wear and tear.
Furthermore, in the subsequent dyeing and filling stages of leather production, aluminium sulfate proves to be useful. It helps in enhancing the overall quality of the leather by facilitating better absorption of dyes and ensuring a more even distribution of filling materials. As a result, the appearance of the leather is significantly improved, with more vibrant colors and a smoother, more consistent surface texture.
Aluminium sulfate plays a crucial role in the leather tanning process. It has the capacity to react with the collagen within leather. This reaction leads to the leather's structure becoming more compact, thereby making it more robust and increasing its longevity.
Moreover, during the leather's dyeing and filling operations, aluminium sulfate can be utilized. Its application in these processes contributes to an improvement in the leather's quality, enhancing aspects such as colorfastness and material integrity. Simultaneously, it also significantly boosts the leather's outward appearance, resulting in a more aesthetically pleasing and marketable product.
