Silica sol boasts a large specific surface area and high reactivity, enabling it to form strong chemical bonds with cationic surfactants and pulp fibers. This enhances retention and filtration efficiency, improving the retention rate of fine fibers and fillers as well as the drainage performance of the pulp. Additionally, the nano-sized silica particles in the silica sol create microscopic pores on the surface, providing excellent color-fixing effects and enhancing the clarity of colored patterns.
