Hebei Messi Biology Co., Ltd. stated that basic magnesium carbonate can be roughly divided into three aspects according to its uses. (1) Used as additives and improvers in food and various chemical products; (2) Used as raw materials for the preparation of magnesium series chemical products; (3) Used in pharmaceuticals and medical auxiliary therapeutic drugs.
High-purity basic magnesium carbonate is non-toxic, tasteless and harmless to human health. Magnesium can enhance the heart function of the human body and has good fluidity. Therefore, adding it to flour as an auxiliary ingredient can It improves the dispersion and fluidity of flour, and can also supplement the body’s demand for electrolytes such as inorganic salts. The addition amount is generally 10% to 15%. Making basic magnesium carbonate into aluminum magnesium carbonate double salt can greatly improve the cure rate of peptic ulcer in the elderly. It can increase the pH value of the stomach and promote tissue regeneration and repair. Since the regeneration and repair of ulcer tissue in the elderly is slow, taking aluminum magnesium carbonate can directly act on the ulcer surface to promote tissue regeneration and improve the ulcer healing rate.
In chemical metallurgy, basic magnesium carbonate can also be added as an additive to some alloys to change the mechanical properties of the alloy. Basic magnesium carbonate can also be used as an excellent filler and reinforcing agent for rubber products, which can improve the output and quality of rubber products. Refined transparent basic magnesium carbonate can also be used in transparent or light-colored rubber products. After it is mixed with rubber, it hardly changes the refractive index of the rubber itself, and can enhance the wear resistance, bending resistance and tensile strength of the rubber. strength.
Because basic magnesium carbonate has the characteristics of non-burning and light and loose texture, it can also be used as heat insulation and high-temperature resistant fireproof insulation material. Asbestos lightweight magnesium carbonate is an excellent insulating material and is used in shipbuilding, boiler manufacturing and other departments. In addition, it can also be used as an additive for paints, inks and coatings, and is also used in toothpaste, medicine, cosmetics, fire retardant coatings, ceramics, glass, pigments and other industries.
However, the main use of basic magnesium carbonate is as an industrial intermediate raw material (or product) to prepare high-purity magnesia or magnesium oxide. Due to some of its own characteristics, magnesium oxide has broad application prospects.
The sintered body of magnesium oxide prepared from basic magnesium carbonate and magnesium hydroxide can reach 93% and 82% of the theoretical density respectively, while the magnesium oxide prepared from magnesium chloride, magnesium sulfate, etc. is sintered under the same conditions. It can reach 66% and 50% of the theoretical density. If the properties of magnesium oxide obtained by calcination are compared, it can be seen that the sintering properties of active magnesium oxide are obtained by using raw material salts that can produce magnesium oxide with small particle size, large lattice constant, small crystallites, and relaxed structure. Good; on the contrary, when magnesium oxide is prepared from raw material salts that generate magnesium oxide with higher crystallinity and large particle size, its sintering properties are poor.
Hebei Messi Biology Co., Ltd. stated that the production of high-purity magnesium oxide through basic magnesium carbonate has the advantages of short reaction process, simple process, low equipment requirements, low production costs, high product activity, and no pollution to the environment. A series of advantages. This method will become one of the important methods for industrial production of high-purity magnesium oxide. Due to the wide range of uses of basic magnesium carbonate, how to prepare refined basic magnesium carbonate has become an issue worthy of discussion.
