Analytical method for fast and accurately measuring density of suspending agent

Abstract

The invention discloses a method for measuring the density of a pesticide suspending agent product. The method can be used for fast and accurately measuring the volume of a certain mass of products through removing air bubbles in a suspending agent in a centrifugal mode so as to measure the density of the product. The method is easy to implement; and with the adoption of the method, the problem that the density of a liquid having high viscosity and containing air bubbles is difficult to measure is solved effectively.

Description

technical field [0001] The invention relates to the technical field of analysis, in particular to an analysis method for rapidly and accurately measuring the density of a suspending agent. Background technique [0002] Suspension concentrate is an important formulation representing the development direction of contemporary pesticide formulation technology. The basic principle is to disperse the original drug into water or oil under the action of surfactant and other additives to form a uniform and stable coarse suspension system. It is mainly composed of pesticide technical, wetting agent, dispersant, thickener, antifreeze, pH regulator, defoamer and water or oil, etc. It has the characteristics of low cost, safe production, storage, transportation and use. Compared with the pesticide dosage forms using organic solvents as the medium, it has the advantages of little impact on the environment and light drug damage. [0003] The main performance indicators of suspension conc...

AI Technical Summary

Problems solved by technology

This makes it impossible to quickly and accurately measure the volume of a given mass of suspension product and thus its density

If the use of ultrasound to eliminate bubbles will cause the thermal expansion of the liquid itself; the use of vacuum degassing will undoubtedly complicate the analysis steps and increase the analysis cost
