Method used for preparing small particle size zinc thiazole

Abstract

The invention relates to a method used for preparing small particle size zinc thiazole. According to a raw material mixing method of the method, a zinc salt solution is added into a thiadiazole salt solution or the thiadiazole salt solution is added into the zinc salt solution, wherein in the process of adding the zinc salt solution into the thiadiazole salt solution, the zinc salt solution / thiadiazole salt solution initial relative speed is controlled to be 20 to 200m / s, or in the process of adding the thiadiazole salt solution into the zinc salt solution, the thiadiazole salt solution / zinc salt solution initial relative speed is controlled to be 20 to 200m / s. The method is capable of realizing preparation of small particle size zinc thiazole without using any auxiliary agent; the reaction mixing step is the key step; in the reaction mixing step, adding speed is accelerated, and with accelerating of the adding speed, the stirring speed is accelerated, so that the particle size of theprepraed zinc thiazole particles can be reduced to be lower than 2mm.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and specifically relates to a preparation method of an antibacterial agent zinc thiazole, in particular to a method for preparing zinc thiazole with a small particle size. Background technique [0002] With the application of thiazole zinc in agriculture, especially the reduction of thiazole zinc particle size improves the activity of thiazole zinc and its good processing performance, there is an urgent need for the preparation of small particle size thiazole zinc. At present, the preparation of small particle size thiazole zinc The method generally stays in the preparation process of zinc thiazole by adding auxiliary agents, especially dispersants. However, the addition of dispersants is for reducing the particle size of zinc thiazole particles. On the one hand, there may be residual added exogenous Substances, on the other hand, add to the difficulty of disposal for the wastewater produced...
