Heavy magnesium carbonate, also known as basic heavy magnesium carbonate, is widely used in flour improvers. It can improve the dispersibility and fluidity of flour improvers and shows good development prospects. Hebei Messi Biology Co., Ltd. uses heavy magnesium carbonate generated under appropriate conditions as white powder, focusing on the influence of raw material concentration reaction cycle on product crystal weighing.
Heavy magnesium carbonate crystals have a maximum bulk density. Grain nucleation and growth are one of the key factors determining the size of crystal particles. The saturation of magnesium carbonate is very large, and when the raw material concentration is low, the rate of carbon dioxide release is large, which also leads to loose precipitation. The raw material concentration is too high or too low, which will cause the product bulk density to decrease. Reaction time is the effect of temperature on the bulk density of heavy magnesium carbonate. Heavy magnesium carbonate crystals have a maximum bulk density. Magnesium carbonate is easy to form an oversaturated state. A large number of crystal nuclei but the solubility of relative magnesium carbonate precipitation will increase, but the immature crystal growth makes the grain growth gradually mature, the grain growth is basically over, and the fluidity is good.
Hebei Messi Biology Co., Ltd. prepared uniformly granulated magnesium carbonate using brine and soda ash as raw materials. The calculated mass fraction of magnesium oxide was 40%~43%, which meets the requirements of food additives.
