The papermaking industry requires precise control over the dispersion of various components to produce high-quality paper products. Dispersing Agent NNO, a form of sodium naphthalene sulfonate formaldehyde condensate, plays a crucial role in this industry by acting as an effective dispersant for wood pulp. Its primary benefit lies in its ability to prevent staining issues that can arise from the condensation of asphaltum, resin, and other materials present in the wood pulp.

By incorporating Dispersing Agent NNO into the wood pulp slurry, manufacturers can achieve a cleaner and more uniform pulp. This prevents the formation of unsightly stains and spots on the final paper product, ensuring a better appearance and printability. Typically used at a dosage of 0.2%-0.5% of the wood pulp's weight, NNO significantly improves the overall quality of the paper. Furthermore, it can function as a precipitator for animal size, aiding in the sizing process of paper to improve its water resistance and printability. The consistent performance of NNO as a dispersant makes it a valuable additive for paper mills seeking to optimize their production processes and deliver superior paper products.
