The Effect of Coating Agent and Preparation on the Thermostability of Coated Potassium Chlorate

Article Preview

Abstract:

In order to improve the thermostability of potassium chlorate particles, microencapsulation method was used to coat potassium chlorate particles. The effects of coating agents on thermostability of coated potassium chlorate particles were investigated by differential thermal analysis (DTA) and optical video microscope. An optimum study of preparation process parameters was carried out by orthogonal design. The results show that the Silane coupling agent kh550 is the most efficient coating agent to inhibit the decomposition of potassium chlorate and result in the improvement of potassium chlorate. The optimal process for the microencapsulation is 5%Silane coupling agent, reaction temperature 40°Cand holding for 3h.
