The paper industry relies on a precise combination of chemicals to achieve desired paper quality, from strength and water resistance to printability and brightness. Among these essential chemicals, sodium aluminate plays a key role in optimizing several stages of the papermaking process. As a leading supplier of industrial chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides high-purity sodium aluminate that enhances paper production efficiency and product quality.

Sodium aluminate, known chemically as NaAlO2 and bearing CAS number 11138-49-1, is an inorganic compound highly valued for its alkaline properties and its ability to provide reactive alumina. In papermaking, these characteristics translate into significant advantages:

Key Roles of Sodium Aluminate in Paper Production:

1. pH Adjustment and Alkalinity Control: Papermaking often involves processes that can alter the pH of the pulp slurry. Sodium aluminate, being an alkaline chemical, is effectively used to increase and maintain the pH level within the desired range. This is crucial for the efficiency of other additives, such as sizing agents, and for controlling the overall papermaking chemistry.

2. Improved Sizing Efficiency: Sizing agents, typically rosin-based, are added to paper to control its absorption of liquids like ink or water. Sodium aluminate reacts with these sizing agents to form insoluble aluminum soaps. This reaction enhances the effectiveness of the sizing process, leading to improved water resistance and printability of the final paper product. When you buy sodium aluminate for this application, you're investing in better paper quality.

3. Enhanced Bonding and Strength: The presence of sodium aluminate can contribute to better interfiber bonding within the paper structure. This results in improved dry strength properties, such as tensile strength and bursting strength, making the paper more durable and robust.

4. Retention and Drainage Aid: In some formulations, sodium aluminate can act as a retention aid, helping to retain fine particles and fillers within the paper web, thereby reducing material loss and improving the efficiency of the papermaking process. It can also influence drainage rates on the paper machine.
