摘要:
Effects of emulsifying chemicals and emulsion aging on the sizing performance of alkenyl succinic anhydride (ASA) were investigated. The emulsifying chemicals were nonionic and anionic surfactants and cationic starches. Image analysis in emulsion quality control was applied. It was found that the use of surfactants may deteoriate remarkably the sizing efficiency if the surfactant and its dosage is not carefully chosen. The need for surfactants in emulsification was affected by the properties of ASA and the mixing energy available. The act of cationic starch both as an effective stabilizer and as a retention agent in ASA-sizing systems was established.
