On December 1, Director Wang Xudong of the Achievements Transformation Center of the Hebei Provincial Department of Science and Technology led an expert team to Xingtai City for investigation. At 9 a.m., in the Lotus Hall of Xishilai Hotel, experts gave lectures on the transformation paths of corporate scientific and technological achievements. Mr. Yao, the head of Hebei Messi Biology Co., Ltd., was invited to participate in this training meeting. Hebei Messi Biology Co., Ltd. is a high-tech enterprise specializing in the field of new magnesium salt materials such as magnesium oxide, magnesium carbonate, magnesium sulfate, and magnesium hydroxide….

Magnesium hydroxide is an important inorganic compound with a wide range of applications. At present, there are three main preparation processes for magnesium hydroxide: 1. Direct precipitation method Direct precipitation method is currently the most commonly used method for industrial production of magnesium hydroxide. The principle of this method is to mix soluble magnesium salt solution and soluble alkali solution, and react under certain conditions to form magnesium hydroxide precipitation. Commonly used soluble magnesium salt solutions include magnesium chloride, magnesium sulfate, magnesium nitrate, etc. Commonly used soluble alkali solutions include sodium hydroxide, ammonia, etc. The direct precipitation method has…

Magnesium oxide has high activity, is light and loose, and is widely used in medicine, food, chemical industry, etc. It is one of the most promising functional materials. Hebei Messi Biology Co., Ltd. stated that the primary magnesium precipitation mother liquor obtained by the brine ammonia precipitation method is used as raw material, and ammonium bicarbonate is used for secondary magnesium precipitation to prepare double salts. The double salts are pyrolyzed to prepare light magnesium carbonate, and finally light carbonic acid. The process of preparing light magnesium oxide by magnesium calcination was also discussed. The recovery and utilization of…

Magnesium hydroxide is an inorganic mineral with good flame retardant, smoke suppression, filling, conductive and other properties, so it is widely used in composite materials. Magnesium hydroxide is one of the most widely used inorganic flame retardants currently and has the following flame retardant mechanism: It decomposes at high temperatures to form magnesium oxide. Magnesium oxide is a high-temperature resistant inorganic substance that can isolate air and prevent combustion. Absorb heat and reduce combustion temperature. Generates inert gas to prevent the spread of combustion. The flame retardant effect of magnesium hydroxide in composite materials depends on its addition amount,…

Hebei Messi Biology Co., Ltd. stated that when preparing magnesium oxide with two morphologies, petal-shaped and fan-shaped, the precursors of the corresponding morphologies are generally prepared first, and then the products are obtained through heat treatment. Using the abundant mineral dolomite in my country as raw material, a method combining two-stage acid leaching and EDTA-ammonia complex precipitation reaction is used to first prepare petal-like magnesium hydroxide, and then heat-treat it to obtain rhombus-shaped petal-shaped magnesium oxide. The arrangement is regular and grows in an epitaxial radial pattern. The product purity is greater than 99.8%, the specific surface area is…

The brine monoammonium bicarbonate method is one of the methods for producing high-quality light magnesium oxide in China. It uses brine as raw material and ammonium bicarbonate and ammonia water as precipitants to produce light magnesium oxide. The process is simple, easy to operate and control, the investment is small, and it is especially suitable for small and medium-scale production. The treatment of ammonia nitrogen in wastewater has attracted widespread attention, and the standards for ammonia nitrogen efflux in ammonia nitrogen wastewater have been continuously improved. 1. Overview of ammonia nitrogen Ammonia nitrogen refers to nitrogen that exists in…

Hebei Messi Biology Co., Ltd. stated that the recently reported preparation methods of flaky magnesium oxide all first prepare flaky magnesium hydroxide precursors, and then heat-treat them to obtain flaky magnesium oxide. Add 1% to 3% of the total weight of the compound surfactant to the 40% to 70% magnesium salt solution. The compound surfactant is a molecular surfactant and an ionic surfactant with a weight ratio of 0.2:1. To a mixture of 5:1, add alkali solution dropwise at 0°C to 50°C. The precipitate is filtered, washed, vacuum dried, and ground to obtain the magnesium hydroxide precursor, which is…

1. Experimental raw materials Natural hydromagnesite (Mg(OH)2·4MgCO3·4H2O) originates from Bangor Lake in Tibet. Pb(NO3)2, HNO3, NaOH and absolute ethanol (analytical grade) were purchased from Sinopharm Chemical Reagent Co., Ltd. (Shanghai). Deionized water was homemade in the laboratory. 24 kinds of ions (Al, As, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, Se, Sr, V , Zn) to prepare a mixed standard solution of 1 000 mg·L-1 for later use. All reagents were used without further purification. 2. Preparation of high specific surface area mesoporous network magnesium oxide adsorption materials…

On November 23, 2023, in order to increase the promotion of industrial diagnostic service models, better help enterprises solve technical, management and other problems faced by transformation and upgrading, and accelerate the transformation and development of high-end, green, and intelligent manufacturing in the city, Xingtai City The Bureau of Industry and Information Technology organized a “diagnosis and consultation” activity in industrial clinics, and Mr. Yao of Hebei Messi Biology Co., Ltd. participated in this activity. The activities are mainly targeted at “SRDI”(Specialized, Refinement, Differential, Innovation) enterprise, “little giant” enterprises, leading enterprises in characteristic industries, industry leaders, high-growth innovative enterprises…

Magnesium hydroxide is a white powder with water absorption, fire resistance, acid resistance and other characteristics. It is widely used in medicine, chemical industry, building materials and other fields. The drying process of magnesium hydroxide is a complex physical and chemical process, which is affected by many factors. The research on drying kinetics of magnesium hydroxide mainly includes the following aspects: Analysis of drying curves and drying rate curves The drying curve of magnesium hydroxide refers to the change curve of the moisture content of wet materials with time. The drying rate curve refers to the rate of change…
