The paper industry relies on a variety of chemical additives to achieve desired product qualities, and aluminum sulphate plays a pivotal role as a paper sizing agent. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-grade aluminum sulphate that is essential for enhancing the performance of paper. Sizing is a critical process that imparts water resistance to paper, preventing ink from feathering or spreading excessively. Aluminum sulphate works in conjunction with rosin or other sizing agents to create a hydrophobic surface on the paper fibers. When aluminum sulphate is added to the pulp, it reacts with the sizing agent to form aluminum rosinate, which is then deposited onto the cellulose fibers. This coating creates a barrier that repels water, making the paper suitable for printing, writing, and packaging. The effectiveness of this paper sizing agent aluminum sulfate is crucial for producing high-quality paper products that meet industry standards. The precise control over paper water resistance directly impacts the printability and overall usability of the final product. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our aluminum sulphate 16% provides consistent and reliable sizing performance.

Beyond its primary role in sizing, aluminum sulphate also acts as a retention aid and drainage enhancer during the papermaking process. It helps to retain fine fibers and fillers within the paper web, improving opacity and reducing material loss. Furthermore, it aids in the drainage of water from the pulp slurry, leading to faster machine speeds and increased production efficiency. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of essential paper chemicals, and our aluminum sulphate is a testament to our commitment to quality and innovation. By utilizing our paper chemical auxiliary, manufacturers can achieve superior paper characteristics, from enhanced water repellency to improved ink holdout.
