NINGBO INNO PHARMCHEM CO.,LTD. supplies premium sodium silicate, a chemical compound that is instrumental in various stages of paper production, significantly contributing to the quality and performance of paper products. Its applications span from pulp treatment to enhancing the final paper characteristics.

In the pulping process, sodium silicate acts as a stabilizer for hydrogen peroxide, a common bleaching agent used to whiten wood pulp. By controlling the decomposition rate of peroxide, it ensures efficient bleaching while minimizing damage to the cellulose fibers. This controlled bleaching process is essential for achieving the desired brightness and purity in paper products, highlighting the importance of sodium silicate paper production.

Furthermore, sodium silicate is widely employed as a sizing agent. Paper sizing controls the absorption of liquids, such as ink or water, preventing feathering and bleed-through. When used as a sizing agent, sodium silicate improves the paper's surface properties, leading to sharper text and images, and a more pleasant writing or printing experience. This application is critical for producing high-quality printing and writing papers.

The compound also contributes to the strength and rigidity of paper. By interacting with cellulose fibers, it can enhance interfiber bonding, leading to increased tensile strength and reduced tearing. This is particularly important for specialty papers, packaging materials, and paperboard that require greater structural integrity.

In the context of de-inking recycled paper, sodium silicate plays a vital role. Its alkaline nature aids in the dispersion of ink particles during the washing process, allowing for more effective removal and thus enabling higher quality recycled paper production. This aligns with sustainability goals within the paper industry.

For paper manufacturers seeking to optimize their processes and produce superior paper grades, NINGBO INNO PHARMCHEM CO.,LTD.'s sodium silicate offers a reliable and effective solution. Its contributions to bleaching, sizing, strength enhancement, and de-inking underscore its indispensable role in the modern paper industry.
