Exploring the Role of Hydrated Aluminium Sulphate Formula in Paper Manufacturing
Latest News from Zhengzhou Mahaco Industrial Co.,Ltd (MAHACO)
The paper manufacturing industry has witnessed significant advancements in recent years, with a strong focus on chemical additives that improve quality and efficiency. Among these, the hydrated aluminium sulphate formula has emerged as a critical component. Zhengzhou Mahaco Industrial Co.,Ltd (MAHACO), a leading supplier of industrial chemicals, continues to innovate and supply high-grade hydrated aluminium sulphate to paper mills worldwide. In this article, we explore the key role of this compound in the paper-making process, its formula, and MAHACO’s contributions to the industry.
What is Hydrated Aluminium Sulphate?
Hydrated aluminium sulphate, commonly known as alum, is a chemical compound with the formula Al₂(SO₄)₃·18H₂O. This formula indicates that each molecule of aluminium sulphate is associated with eighteen molecules of water, making it a hydrated salt. The compound appears as a white crystalline solid and is highly soluble in water, which makes it ideal for use in aqueous processes such as paper manufacturing.
The Role of Hydrated Aluminium Sulphate in Paper Manufacturing
In the paper industry, hydrated aluminium sulphate serves primarily as a retention agent and fixing agent. Its primary function is to help bind the cellulose fibers and fillers, improving paper formation and enhancing the finished product’s quality. The addition of hydrated aluminium sulphate formula to the pulp aids in the precipitation of rosin size, which is essential for making the paper water-resistant. This process is known as paper sizing.
Furthermore, the presence of aluminium ions facilitates the flocculation of fine particles, resulting in better retention of fillers and improved drainage on the paper machine. This not only increases the yield but also reduces the environmental impact by minimizing the loss of fine materials in the wastewater.
