农药悬浮剂是国际上公认的代表制剂技术发展方向的一类重要剂型。该剂型起源于上个世纪40年代中期,英国是最早研究和应用悬浮制剂的。我国从上世纪70年代初期研究并生产悬浮剂,至2005年后期发展迅速,并成为重要的剂型之一。该剂型加工技术复杂,步骤多,难度较大。其技术涉及到化学、物理、机械等多门学科,基本投资费用大,加工成本较高。因此,产品的稳定性如分层、絮 Pesticide suspending agent is internationally recognized as an important type of formulation representing the direction of formulation technology. The dosage form originated in the mid-1940s, the United Kingdom is the earliest research and application of suspended preparations. China from the early 70s of last century to study and produce SC, to the late 2005 rapid development, and become one of the important dosage form. The dosage form processing technology is complex, more steps, more difficult. Its technology involves chemical, physical, mechanical and other disciplines, the basic investment costs, higher processing costs. Therefore, the stability of the product, such as stratification, floc
