Heavy Magnesium Carbonate VS Light Magnesium Carbonate

Magnesium carbonate can be divided into light & heavy magnesium carbonate, they have different definition and production process. As the domestic largest comprehensive enterprise of R&D, production, sales for magnesium salt compound, Meishen Technology has own more than 20 years experience, now we will have a detailed introduction for you.

The melting point of magnesium carbonate is about 2825 ℃, poorly soluble in water and organic solvents, soluble in acid or ammonium salt solution, solubility increased in water due to the existence of carbon dioxide. After above 1000 ℃ high temperature burning, can be converted to crystal. When the temperature up to 1500 ℃ or above, it becomes dead burned magnesium oxide and sintered magnesium oxide. Secondly, it will generate into magnesium carbonate double salts after meeting carbon dioxide from the air.

Heavy magnesium carbonate is closely volume of white or yellowish powder, easy to combine with water. Dew put in the air, easy to absorb moisture and carbon dioxide in the air, and mixed with magnesium chloride solution easily gelation hardening.

Heavy magnesium carbonate is usually produced by directly calcining water magnesium quarry and magnesite. In general, the bulk density is 0.5 g/ml. But light magnesium carbonate is produced by magnesium sulfate, magnesium chloride or magnesium bicarbonate soluble into water, then through chemical method, and calcined into magnesium carbonate. Bulk density is small, usually is 0.2 g/ml. In addition, heavy magnesium carbonate is widely used in fiber glass steel, cement, etc. Light magnesium carbonate mainly as raw material of enamel, ceramic, refractory, refractory crucible. Also can be used as the filler of adhesive, polishing agent, paper, paint, or used as activator and promoter of neoprene.

Medical Magnesium Carbonate Heavy

During the preparation of medical heavy magnesium carbonate, the main factors influencing the product are magnesium oxidecontent, bulk density, etc. Soda ash and brine as the raw material, the metathesis reaction after pyrolysis, separation, drying then get medical heavy magnesium carbonate. Concentration of reactants, reaction temperature and reaction time directly affects the quality of the products. The preparation technology of medical heavy magnesium carbonate, control the reactant concentration are (20～25)g*L－1 Mg2＋,(88～11)g*L－1NaCO3. Reaction temperature: Double decomposition reaction under normal temperature, pyrolysis temperature control at about 90 ℃. The reaction time is 3 ~ 4 h, drying temperature is about 100 ℃.

    Hebei Meishen Chemical Technology Co.,LTD is the professional pharmaceutical grade and food grade magnesium carbonate manufacturer in China. Metathesis using domestic unique production, twice purify by thousands of degrees of high temperature calcination to produce pharmaceutical grade magnesium carbonate. We have reached the EU standards, which is far better than the national pharmacopoeia standards. The quality of the finished product can effectively avoid accidents due to drug failure caused by substandard quality magnesium carbonate.

The Application of Pharmaceutical Grade Magnesium Carbonate

The Application of Pharmaceutical Grade Magnesium Carbonate:

1. Magnesium carbonate is used for gastric ulcer and duodenal ulcer. Canker or peptic ulcer is a common digestive tract disease, can occur in the esophagus, stomach, or duodenum, the abdominal pain is the main symptoms of this disease.

2. Magnesium carbonate is used for Acute and chronic gastritis and duodenal ampulla inflammation. Magnesium carbonate can stimulate the gastric mucosa prostaglandin E2 synthesis, thereby enhancing the “gastric mucosal barrier” effect.

3. Magnesium carbonate is used for Reflux esophagitis. Reflux esophagitis (RE) is from the stomach, duodenal contents into the esophagus caused by esophageal inflammatory lesions, endoscopic esophageal mucosal damage showed, that is esophageal erosions and (or) esophageal ulcers.

4. Magnesium carbonate is used in related to gastric acidity of the stomach discomfort. Magnesium carbonate can quickly neutralize stomach acid, effect lasting. Magnesium carbonate as antacids, compound hydroxide are similar, but they have a mild persistent effect, and can react with hydrochloric acid in gastric juice fully, response rate can reach 98% ~ 100%.

Magnesium Carbonate – Food Additives

Characters:
Because of the different crystallization conditions, this product can be divided into light and heavy magnesium carbonate. Light magnesium carbonate include: MgCO3·H2O. Heavy magnesium carbonate include: 5MgCO3·Mg（OH）2·3H2O, 5MgCO3·2Mg（OH）2·7H2O, 4MgCO3·Mg（OH）2 and 3Mg（OH）2·4H2O.

Production Method:
1.Deal with magnesite (MgCO2) or dolomite (MgCO3.CaCO3), process to make it.
2.The magnesium sulfate and sodium carbonate precipitation reaction after refining。

Toxicology Basis：
1.GRAS FDA-21 CFR 182, 145.
2.ADI without provisions(FAO/WHO, 1994).

It is usually used as flour treatment agent, anti-caking agents, leavening agents.

1.Matters need attention in use. The product has acid-suppressing effect for stomach, overdose can cause diarrhea.

2.Scope and Usage
(1) China’s <<Food Additives Health Standards>> regulations: Magnesium carbonate can be used for wheat flour, the maximum dosage is 1.5 g/kg.
(2) FAO/WHO (1983) regulations: it can be used as an anti-caking agent milk and cream powder, the maximum amount was 10g / kg and 1g / kg. Moreover it can also used in chocolate, cocoa powder.

High Standards of Medical Magnesium Carbonate Supplier

Hebei Meishen Technology Co.,LTD is the largest and most professional medical magnesium carbonate supplier in China. We invest more than 10 million to buy the most advanced equipment, and to realize full-computer control. Workshops are automatic line production, so we do not need a lot of staff.

What is required to prepare for staff entering the medical magnesium carbonate workshop operations ? Dressed in a white coat and wearing a headset. Only go through the staff channel can enter into the workshop, each employee a card to enter. Before entering the workshop, equipped with automatic faucets sink to wash clean and dry, after alcohol spray opponents secondary sterilization. Finally, go through the wind channel, then the wind blowing from different perspectives, blow the people all the dust and debris on the body. After these preparations employees can access finished workshop. Production workshop preparation is capped with more than 50 uv lamp, it should be carried out one hour of UV germicidal during the rest period. In between magnesium carbonate cooling and packing room, the installation of two sets of one hundred thousand air purification unit, the air is filtered and sterilized to ensure high cleanliness.

Application of high-purity magnesium carbonate in rubber

    As a important ingredient in the production of rubber products, magnesium carbonate makes it have the properties of high mechanical strength, good wear resistance, corrosion resistance and others. High-purity magnesium carbonate is one of the rubber compounding, playing a role of reinforcing filler. In the process of mixing operation, adding with other compounding into plastic rubber with a certain degree of plasticity, then you can get rubber compounds. High-purity magnesium carbonate is better than calcium carbonate in reinforcing effect, and has better heat resistance, the time of enhancing hardness is faster, so it is suitable for transparent or translucent rubber.

    Although high-purity magnesium carbonate is the colorless and odorless dust, you will get lung disease if long-term inhalation of pulmonary, so we had better wear a mask in the workplace. In the process of transportation, there are some problems needing to be payed attention. Make sure the packing is complete, can't leak, shall not be damaged. You can't mix with oxidant, and prevent from isolation, rain, high temperature in the transport process.
