Application and characteristics of magnesium carbonate

2022-05-30

Magnesium carbonate is generally white powder, which is divided into pharmaceutical grade and industrial grade. Magnesium carbonate is a common desiccant and anti-hardening additive used primarily in granular and powdered materials to prevent them from clumping and clumping and to keep them loose or free-flowing. The principle of anti-caking agents is usually to absorb excess moisture or attach to the particle surface to make it hydrophobic. The water absorption of magnesium carbonate can effectively prolong the shelf life of materials, prevent moisture and avoid caking.

Magnesium carbonate is non-toxic. It is a white granular powder that is soluble in water and can be used as a food additive. It can be used in many chemical reagents and rubber, and can also be used to make thermal insulation materials. Magnesium carbonate has very good high temperature resistance. It can be used as oxidizing agent, bleaching agent, catalyst, disinfectant, corrosive agent, anti-shrinking agent for wool and sewage treatment agent. Because magnesium carbonate has certain fire-fighting properties, it is also used in many fire-fighting products. In addition, magnesium carbonate products can be used in ceramics, cosmetics, glass products and other industries.

The production technology of magnesium carbonate abroad is very mature, but there is a big gap between domestic products and international ones, especially the agglomeration problem during storage. Adding magnesium carbonate, an inert anti-caking agent, to this product can effectively improve the anti-caking ability of the product in natural or dry environments. In general, magnesium carbonate has many functions and a wide range of uses.

As a small product in the chemical industry, although the amount of magnesium carbonate is very small, it has a wide range of uses and its importance is self-evident. Due to the relatively low density of magnesium carbonate, it can be added to rubber products as a filler and reinforcing agent. Magnesium carbonate also has the characteristics of low ignition point and loose texture. Magnesium carbonate is also used as an excellent thermal insulation material in the shipbuilding and boiler industries.

Medicine is a potential application field of magnesium carbonate in my country. The consumption of magnesium carbonate will increase steadily, and the market prospect is promising. Looking at the domestic magnesium carbonate market, in the economically developed coastal areas of Jiangsu and Zhejiang, with Shanghai as the center, the manufacturing level of rubber, plastic, ink, paper and other products is relatively high, the demand for magnesium carbonate is large, and the quality requirements are high. The main demand is high-value-added magnesium carbonate such as high-purity magnesium carbonate and ultra-fine magnesium carbonate.

In addition to the above industries, magnesium carbonate has a role in many industrial fields. For example, magnesium carbonate can be calcined to produce magnesium oxide, which can be further used in glass products, magnesium salt chemicals, ceramics, cosmetics, toothpaste, pigments, paints, refractories, printing inks and other industries. And with the continuous update of magnesium carbonate production technology, more functions of magnesium carbonate will be discovered, which will greatly reduce the cost of using magnesium carbonate and be more widely used in various industrial fields.
