As an efficient, environmentally friendly and safe form of pesticide preparation, pesticide suspension has been widely used in agriculture, forestry and public health because of its good dispersion and stability. However, the viscosity of a pesticide suspension has an important impact on its properties. High viscosity may lead to clogging of the nozzle and affect the spraying effect; If the viscosity is too low, it may lead to insufficient dispersion of the liquid and reduce the efficacy of the drug. Therefore, accurate measurement of the viscosity of pesticide suspensions is essential to optimize formulations, improve product quality, and ensure effective application. The NDJ-5S digital display Rotational Viscometer has become a reliable choice for measuring the viscosity of pesticide suspensions due to its high precision, high sensitivity and easy operation.

Pesticide suspensionThe viscosity directly affects its fluidity and spraying performance during the application process. By accurately measuring viscosity, the formulation of the suspension can be optimized, ensuring its stability and application effectiveness under different environmental conditions. For example, viscosity control is one of the key factors in the development of highly concentrated oil suspensions. By adding a highly effective dispersant, the viscosity of the suspension can be significantly reduced, while its stability and flowability can be improved. In addition, viscosity measurement can help assess the stability of suspensions during storage and prevent delamination, flocculation and agglomeration.
