"Ritai" brand CMC for papermaking is in granular form, easy to dissolve, and does not clump in water, allowing direct addition to the batching hopper. It serves as a paper smoothener and sizing agent in the papermaking industry. Adding 0.1% to 0.3% CMC to pulp can enhance the tensile strength of paper by 40% to 50%, increase compressive rupture by 50%, and increase flexibility by 4 to 5 times. In the paper adjustment process, it acts as an internal additive or surface sizing agent, providing moderate water retention, preventing penetration into the synthetic sizing, and enhancing the effect of the sizing agent to achieve the desired sizing effect with minimal amount.
Features:
1. High purity, low Na-content, fewer molecules with positive charge in the paint, less prone to structural viscosity, fewer insoluble substances, and high transparency; 2. High substitution rate, good water solubility, and enhanced hydrogen bonding with water molecules in the paint.
