Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is a weak base. It has three main uses. One is used as a polymer filler and acts as a flame retardant. As a new type of flame retardant, magnesium hydroxide has the advantages of being non-toxic, non-volatile, not producing corrosive gases, and having a long-lasting effect. Secondly, it is used in environmental protection to treat acidic waste gas, waste liquid treatment, heavy metals and organic matter. In waste liquid treatment, exhaust desulfurization and other environmental protection measures, it is safe to use and pollution-free. It is a preferred green…

Hebei Messi Biology Co., Ltd. stated that it used salt lake brine to prepare silicon steel grade magnesium oxide. It used X-ray diffractometer, laser particle size analyzer, high and low vacuum scanning electron microscope and other analytical instruments to investigate the calcination of brine magnesium precipitation and calcination process to prepare silicon steel grade magnesium oxide. During the process, the calcination temperature and calcination time affect the activity, morphology and particle size of magnesium oxide. The results show that as the calcination temperature increases and the calcination time prolongs, the activity of magnesium oxide gradually decreases; as the calcination…

Hebei Messi Biology Co., Ltd. stated that magnesium oxide is a typical alkaline earth metal oxide, which is widely used in industry, medicine, food and other fields. Nano-magnesium oxide has surface effect, volume effect, etc. Its performance is superior to ordinary magnesium oxide and can be used in new fields such as electronic ceramics and catalysts. However, nano magnesium oxide is easy to agglomerate and its morphology is difficult to control, which limits its application. Spherical nano-magnesium oxide agglomerated powder has the advantages of large specific surface area and uniform particle size distribution. Therefore, it has high reactivity, strong…

Hebei Messi Biology Co., Ltd., as the only magnesium salt manufacturer at the 23rd China International Industrial Expo, demonstrated its professional production and research and development capabilities for magnesium salt series products. Hebei Messi Biology Co., Ltd. is a company specializing in the production of magnesium salt series products such as magnesium oxide, magnesium carbonate, and magnesium hydroxide. It was established in 2015 with a registered capital of 55 million and is located in the High-tech Zone, Xingtai City, Hebei Province. The company insists on taking science and technology as the guide, focusing on scientific research, based on practice,…

Hebei Messi Biology Co., Ltd. said that magnesium oxide is an important inorganic chemical substance, medical, food, adhesives, rubber, plastics, ceramics, metallurgy, electronics and other industries are of great significance, playing a pivotal role in the national economy. Magnesium oxide with special morphology has a broader market in some areas. Special appearance of magnesium oxide usually can not be prepared directly through the experiment, usually the first preparation of special appearance of the precursor, such as magnesium carbonate or magnesium hydroxide, and then after roasting to get a unique appearance of magnesium oxide. The main raw materials for magnesium…

Hebei Messi Biology Co., Ltd. invention disclosed a petroleum catalyst special magnesium oxide production process, including the following steps: to anhydrous magnesium chloride with water to dissolve for the removal of impurities to remove the calcium, sulfate, iron, manganese, and then add the extractant in the acidic medium with H + ions, followed by the passage of high purity carbon dioxide, the formation of magnesium bicarbonate pyrolysis at low temperature conditions, and ultrasonic assisted pulverization, the generation of 8MgCO3-Mg(OH)2-2H2O. Generate 8MgCO3-Mg(OH)2-2H2O, and finally filtering, washing, the generated filter cake in the lock-type kiln calcination and maintain a certain heating…

Magnesium carbonate for cosmetics is a white or slightly yellow amorphous powder with adsorption, covering, smoothness and other characteristics. It is often used in cosmetics as an adsorbent, filler, covering agent, thickener, etc. The preparation processes of magnesium carbonate for cosmetics mainly include the following: Calcination method: Calcining natural magnesite or magnesite at high temperature to generate magnesium carbonate and carbon dioxide. Hydrolysis method: Dissolve metal magnesium or magnesium oxide in water, then add carbon dioxide for hydrolysis to generate magnesium carbonate. Magnesium carbonate emulsion method: vacuum dry the magnesium carbonate emulsion to obtain magnesium carbonate powder. Among them,…

Magnesium hydroxide (Mg(OH)2) is a white, odorless powder with good adsorption, dispersion and fluidity. It has a wide range of applications around the world, mainly including the following aspects: Flame retardant: Magnesium hydroxide is a non-toxic, odorless, non-polluting and environmentally friendly flame retardant. It is widely used in plastics, rubber, coatings, paper, fibers and other materials. It can effectively inhibit the spread of fire and protect personal safety and property. Antacids: Magnesium hydroxide is an alkaline substance that can neutralize gastric acid and relieve symptoms such as hyperacidity and gastric ulcers. Emulsifier: Magnesium hydroxide can emulsify oil and water…

Hebei Messi Biology Co., Ltd. says that since the development of a suitable chrome tanning process for leather in 1858, about half of the publications on tanning chemistry and tanning technology have been devoted to the improvement of chromium utilization. There are four main methods, i.e. control of pH, selection of masking agent, control of time and temperature, and control of liquor pH control, not only by adding more neutralizing agents to raise the pH in the later stages of tanning, but also by incorporating more modern techniques such as the addition of magnesium oxide, a crystalline soluble alkalinizing…

Hebei Messi Biology Co., Ltd. stated that compared with aluminum hydroxide, the flame retardant and smoke elimination mechanisms of active magnesium hydroxide are very similar to those of aluminum hydroxide, but active magnesium hydroxide has many outstanding advantages that aluminum hydroxide does not have. First of all, the decomposition temperature of magnesium hydroxide is relatively high, and it does not start to decompose into water and magnesium oxide until it is heated to 340°C. It not only has a good flame retardant effect, but can also meet the market’s demand for flame-retardant FRP with higher temperature resistance. Secondly, the…

One of the main influencing factors of eutrophication of rivers and lakes is ammonia nitrogen pollution. At present, my country’s annual output of synthetic urea and ammonia is more than 40 million tons. The production of various ammonia nitrogen products causes enterprises to discharge large amounts of ammonia nitrogen wastewater. At the same time, nature produces ammonia nitrogen wastewater during the process of garbage fermentation. The total amount exceeds hundreds of millions of tons every year, which has a great impact on the natural environment. The mechanism of magnesium oxide treating ammonia nitrogen wastewater Magnesium oxide is a metal…

Hebei Messi Biology Co., Ltd. stated that magnesium sulfate heptahydrate was prepared by using salt lake magnesium chloride and sulfuric acid, and magnesium sulfate heptahydrate was dehydrated to obtain anhydrous magnesium sulfate. Using natural gas to reduce and pyrolyze anhydrous magnesium sulfate to obtain high-purity magnesium oxide. The effects of reduction pyrolysis temperature, pyrolysis time, magnesium sulfate particle size and natural gas gas flow rate on magnesium sulfate conversion rate were investigated through single-factor experiments, and the conditions for reduction pyrolysis were optimized through orthogonal experiments.
