A kind of method for preparing zinc thiazole with micro particle size

Abstract

The invention relates to a method for preparing zinc thiazole with small particle size, which is characterized in that the way of mixing raw materials is that zinc salt solution is added to thiadiazole salt solution or thiadiazole salt solution is added to zinc salt solution, wherein the zinc salt In the process that the solution is added to the thiadiazole salt solution, the initial relative velocity of the zinc salt solution and the thiadiazole salt solution is 20-200 m / s, or, during the addition of the thiadiazole salt solution to the zinc salt solution, the thiadiazole The initial relative velocity of the salt solution and the zinc salt solution is 20-200 m / s. The micro-particle thiazole zinc method of the present invention can realize the preparation of micro-particle thiazole zinc without additives. The key technology lies in the reaction mixing step, which increases the adding speed, and when the adding speed increases, the stirring speed There is also a need for improvement so that the particle size of zinc thiazole particles prepared in this way can be reduced to below 2 microns.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, in particular to a method for preparing an antibacterial agent zinc thiazole, in particular to a method for preparing zinc thiazole with small particle size. Background technique [0002] With the application of zinc thiazole in agriculture, especially the reduction of the particle size of zinc thiazole improves the activity of zinc thiazole and its good processing performance, there is an urgent need for the preparation of zinc thiazole with small particle size. The method generally stays by adding auxiliary agents, especially dispersants, during the preparation of zinc thiazole. However, the addition of dispersants can reduce the particle size of zinc thiazole particles. On the one hand, there may be residual added exogenous sources in the particles. Substances, on the other hand, increase the difficulty of treatment for the generated wastewater. For example, the scheme disclosed in the p...
