聚羧酸盐分散剂在农药剂型产品中的应用

Application of Polycarboxylic Acid Salt Dispersants in Pesticide Formulations

传统的分散剂在分散介质中对农药粒子的分散稳定有一定作用,但容易从农药粒子表面上脱吸,对于稳定和分散农药粒子有一定的局限性。目前聚羧酸盐分散剂以其独特的分散和崩解性能,在众多使用的农用分散剂中脱颖而出,成为最引人注目的农用分散剂。论述了聚羧酸盐分散剂的进展、作用、特点、研发动态、国内外产品以及在悬浮剂、水分散粒剂和其他剂型产品中的应用。

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.
