Application of Polycarboxylic Acid Salt Dispersants in Pesticide Formulations
HUA Nai-zhen;Shenyang Research Institute of Chemical Industry Co.,Ltd.;
Traditional dispersants in the dispersed medium play a important role on dispersion stability of pesticide particles, but the dispersants are easy to desorb from the surfaces of pesticide particles, therefore, the dispersants have limitations for the stability and dispersion of pesticide particles. The polycarboxylic acid salt powders have unique dispersion and disintegration performances, and become the most eye-catching agricultural dispersant. The progress,function, characteristic and development trend, products at home and abroad of polycarboxylic acid salt, as well as the applications in SC, WG and the other formulation products were discussed.
