كربونات المغنيسيوم: A Comprehensive Overview of Applications in Multiple Industries

Pharmaceutical and Health Industry: Pharmaceutical Excipients and Health Ingredients

• Antacid and Gastric Medicine Formulations: As an antacid, magnesium carbonate can neutralize excess gastric acid in the stomach, relieving symptoms such as stomach pain and heartburn caused by excessive gastric acid. Its effect is mild and long-lasting, and it is often used in combination with aluminum hydroxide, calcium carbonate, إلخ., to reduce the side effects of a single component (such as constipation that may be caused by calcium carbonate).
• Laxatives and Digestive Regulation: After oral administration, it reacts with gastric acid in the intestine to generate carbon dioxide and magnesium ions, stimulating intestinal peristalsis. At the same time, the osmotic effect of magnesium ions can promote defecation, which is used to treat functional constipation.
• Nutritional Supplements: As a source of magnesium, it is used to prevent and treat magnesium deficiency. Magnesium is an essential mineral for the human body, participating in key physiological processes such as energy metabolism and nerve conduction. كربونات المغنيسيوم, with moderate absorption rate, is often made into tablets or capsules.
• Pharmaceutical Excipients: As fillers and disintegrants in tablets and powders, it can improve the formability and dissolution rate of drugs, ensuring the stable release of medicinal effects.

Rubber and Plastics Industry: Key Additives for Performance Improvement

• Rubber Industry:
  • As a reinforcing agent and filler, it is used in the processing of natural rubber and synthetic rubber (such as styrene-butadiene rubber, neoprene). Adding magnesium carbonate can improve the tensile strength, wear resistance, and aging resistance of rubber products, while reducing production costs. For example, in products such as tires, hoses, and seals, magnesium carbonate is used in combination with carbon black, silica, إلخ., to balance the hardness and elasticity of the material.
  • As an activator of vulcanization accelerators, it can speed up the vulcanization rate, improve vulcanization efficiency, and ensure the stability of the cross-linked structure of rubber products.
• Plastics Industry:
  • As a flame retardant synergist in PVC, PP and other plastics, it cooperates with flame retardants such as magnesium hydroxide and aluminum oxide to enhance the flame retardant performance of materials, and at the same time improve the processing fluidity of plastics.
  • As a white filler, it enhances the whiteness and opacity of plastic products, which is suitable for products with appearance requirements such as packaging materials and home appliance shells.

Coatings and Building Materials Industry: Functional Additives and Lightweight Materials

• Coatings Industry:
  • As an extender pigment, it is used in systems such as latex paints and anti-corrosion coatings, which can improve the hiding power, wear resistance, and anti-settling properties of coatings, and at the same time reduce the amount of high-priced pigments such as titanium dioxide, saving costs.
  • In fire-resistant coatings, magnesium carbonate decomposes when heated to release carbon dioxide, which plays a role in flame retardancy and smoke suppression, and forms a synergistic effect with other flame-retardant components.
• Building Materials Field:
  • It is used in the production of lightweight partition boards, thermal insulation materials, إلخ. Taking advantage of its low density (about 2.9g/cm³) and heat insulation, it reduces the self-weight of buildings while improving the thermal insulation effect.
  • As a flux in ceramic production, it can reduce the firing temperature, improve the density and gloss of ceramics, and is often used in the manufacture of sanitary ceramics and daily-use ceramics.

Food and Daily Chemical Industry: Safe Additives and Functional Ingredients

• Food Industry:
  • As an anti-caking agent, it is used in powdered foods (such as flour, milk powder, spices) to prevent particles from caking and maintain fluidity. For example, adding a small amount of magnesium carbonate to table salt can prevent it from caking due to moisture absorption.
  • As a leavening agent, it is used in baked foods (bread, biscuits) in combination with sodium bicarbonate. When heated, it decomposes to produce carbon dioxide, making the food form a loose structure.
  • As a nutritional fortifier, it supplements magnesium in food, which is used in functional drinks, nutritional cereals and other products.
• Daily Chemical Industry:
  • As an abrasive in toothpaste, its mild abrasiveness can remove dental plaque and food residues without damaging tooth enamel, and it works with fluoride to clean and protect teeth.
  • As a filler and adsorbent in cosmetics, it is used in products such as loose powder and foundation, which can absorb skin oil and improve the adhesion and skin feel of the products.

Metallurgy and Environmental Protection Industry: Auxiliary Materials and Purifying Agents

• Metallurgical Industry:
  • As an additive in refractory materials, it is used in the linings of high-temperature furnaces for steelmaking, magnesium smelting, إلخ., to improve the high-temperature resistance and corrosion resistance of the materials.
  • As a raw material in magnesium alloy production, it is decomposed into magnesium oxide by calcination, and then metal magnesium is prepared through electrolysis and other processes.
• Environmental Protection Field:
  • It is used in wastewater treatment to remove heavy metal ions (such as lead, nickel) and phosphate in water through adsorption and precipitation, reducing water pollution.
  • In flue gas desulfurization, magnesium carbonate slurry reacts with sulfur dioxide to generate magnesium sulfate, achieving the purpose of desulfurization, and the by-products can be recycled, which is in line with the concept of circular economy.

Sports and Athletics Field: Special Functional Materials

• Sports Goods:
  • As “anti-slip powder”, it is widely used in gymnastics, weightlifting, rock climbing and other events. After athletes apply it, magnesium carbonate powder can absorb sweat from the palms, increase friction, prevent equipment from slipping, and improve the stability and safety of movements. This application requires high purity to ensure no impurities irritate the skin.
