Cationic starch is a starch derivative that introduces tertiary amine or quaternary ammonium groups into the starch macromolecule, giving it cationic properties.
Properties and Characteristics
1. Adsorption: Cationic starch has a strong adsorption capacity for negatively charged substances. This is due to electrostatic interactions, allowing it to adsorb onto fiber surfaces. It has wide applications in the paper and textile industries; for example, in papermaking, it can adsorb onto pulp fibers to enhance the strength and retention/filtering performance of the paper.
2. Dispersion Stability: Cationic starch has good dispersion stability in water. Due to its positive charge, it can prevent the aggregation of starch particles in aqueous solution through electrostatic repulsion. This allows cationic starch solutions to maintain a uniform state for a long time without precipitation or stratification.
Application Fields
1. Papermaking Industry: This is one of the largest application fields for cationic starch. It is used as a strengthening agent and retention/filtering agent for paper. As a strengthening agent, cationic starch can form hydrogen bonds and electrostatic adsorption with paper fibers, increasing the tensile strength, burst resistance, and other physical properties of the paper. As a retention/filtering agent, it can improve the retention rate of fine fibers and fillers in paper, reduce white water loss during papermaking, and enhance papermaking efficiency.
2. Textile Industry: Used for fabric sizing treatment. Cationic starch can tightly bond with textile fibers to form a protective film; at the same time, its positive charge can reduce static electricity between fibers, making fabrics smoother.
3. Wastewater Treatment: It can be used as a flocculant. Because it can adsorb negatively charged suspended particles in water, causing these particles to aggregate into larger flocs that are easier to settle or filter out, thus achieving the purpose of purifying wastewater.
