微乳剂属热力学稳定体系。这是许多科技前辈研究了大量的微乳剂后得出的科学结论。实际上所有的农药制剂的稳定性都与制剂的热力学平衡有关。农药制剂出现的物理化学变化如粉剂结团结块、发粘、分解、悬浮率降低以及液体制剂出现的变浊、分层、沉淀、结晶、乳化性能变差、有效成分分解率超标等等都是农药制剂处于热力学不平衡状态所造成的。所以所有的农药制剂不管是固体、液体、气体制剂都应力求使其处于热力学稳定状态或基本接近处于热力学稳定状态才能保证农药质量符合剂型标准要求。
Microemulsion is a thermodynamically stable system. This is the scientific conclusion that many scientific predecessors came out after studying a lot of microemulsions. In fact, the stability of all pesticide formulations are related to the thermodynamic balance of the formulation. Pesticide formulations such as the physical and chemical changes occur as caking, agglomeration, stickiness, decomposition, suspension, and liquid formulations of the emergence of turbidity, stratification, precipitation, crystallization, emulsification worse, the decomposition rate of active ingredients and so on are Pesticide formulations are caused by thermodynamic imbalances. Therefore, all pesticide formulations, whether solid, liquid, gas formulations should strive to make it in a thermodynamically stable state or almost in a thermodynamically stable state in order to ensure that the quality of pesticides meet the requirements of the dosage form.
