农药水悬浮剂是以水为连续相,固态农药为分散相,在砂磨等外力和润湿剂、分散剂、增稠剂、防冻剂、杀菌剂等助剂作用下,形成的一种热力学不稳定体系。高浓度悬浮剂有许多优点,如无粉尘、无溶剂、高悬浮率、较低的包装体积和生产成本。但高浓度悬浮剂研制中存在的难于砂磨、易于絮凝和聚结、奥氏熟化、易粒径增长、泡沫多难消泡、生产时配制均匀浆料难度大等问题。 Pesticides water-based suspending agent is a kind of thermodynamics formed by water as continuous phase and solid pesticide as dispersed phase under the action of sanding and other external force and wetting agent, dispersant, thickener, antifreeze agent and bactericide etc. Unstable system High concentrations of SC have many advantages, such as no dust, no solvent, high suspension rate, low packaging volume and production cost. However, there are some problems in the development of high concentration suspending agent, such as difficult sanding, easy flocculation and coalescence, aging of austenite, easy particle size growth, difficulty in foam defoaming and difficulty in preparing uniform slurry in the production.
