A PROCESS FOR PRODUCING SODIUMSESQUICARBONATE POWDER OF NANOMETER SIZE

摘要

The present invention comprises the steps of (a) mixing the anhydrous soda ash with water to produce a uniform aqueous soda ash solution; (b) injecting carbon dioxide into the produced aqueous solution and then heating the reaction; (c) pressurizing the aqueous solution in which the carbon dioxide is injected and reacting to form a slurry, and (d) drying the formed slurry to produce a powder, wherein the nanometer-sized sodium sesqui Provided are methods for preparing carbonate powders.;According to the method of the present invention, a small amount of raw material is required and the process is simple. In addition, it is superior to other products in terms of crystal structure and density, and has a nano-sized fine particle form, and shows excellent performance in terms of quality and effects such as fluidity, solubility, and liquid content.;Sodium Sesquicarbonate, Soda Ash, Water, Nanometer
