Magnesium Carbonate

Hebei Messi Biology Co., Ltd. stated that it uses the sol-gel method to prepare nano-magnesium oxide using magnesite, hydrochloric acid and urea as raw materials, and adding the gelling agent polyethylene glycol. The effects of calcination temperature, gelling agent molecular weight, dispersing agent and their dosage on the experiment were investigated. The results show that […]

Hebei Messi Biology Co., Ltd. stated that heavy magnesium carbonate is one of the important components of food additives and can affect the performance of flour. Heavy magnesium carbonate was prepared according to the metathesis reaction. The effects of raw material concentration, reaction temperature, reaction time and other conditions on magnesium carbonate grains were studied,

Hebei Messi Biology Co., Ltd. stated that magnesium carbonate whiskers, as a typical functionalized magnesium carbonate product, are single crystals of hydrated magnesium carbonate. They have unique advantages such as fewer defects, fewer impurities, and a strength close to the ideal strength of the crystal. Magnesium carbonate whiskers are cheap and widely used. They can

Hebei Messi Biology Co., Ltd. stated that China is a country with many salt lakes. Starting from the southern end of the Greater Khingan Mountains in the northeast, and along the northern end of the Yinshan Mountains, the eastern end of the Qilian Mountains, and the Gangdise Mountains, there are about 1,000 salt lakes. Qinghai,

Hebei Messi Biology Co., Ltd. stated that the main magnesium-containing minerals on the earth include magnesite, spar and dolomite. In the traditional industry, basic magnesium carbonate is mainly produced from these ores as raw materials. The main production methods are: dolomite carbonization method, magnesite ammonium carbonate method, bitter soil powder-sulfate-ammonium bicarbonate method, etc. The specific

Hebei Messi Biology Co., Ltd. stated that basic magnesium carbonate can be roughly divided into three aspects according to its uses. (1) Used as additives and improvers in food and various chemical products; (2) Used as raw materials for the preparation of magnesium series chemical products; (3) Used in pharmaceuticals and medical auxiliary therapeutic drugs.

Hebei Messi Biology Co., Ltd. stated that anhydrous magnesium carbonate can be used as a carrier in medicines. The magnesite ore is broken into pieces and put into a multi-position parallel reaction synthesizer flask. Water is added and carbon dioxide is introduced at the same time. Prepare magnesium bicarbonate, magnesium bicarbonate and magnesium hydroxide as

Hebei Messi Biology Co., Ltd. stated that anhydrous magnesium carbonate particles with an average particle size of 1.267 μm are prepared from light-burned powder as raw material through digestion, carbonization, heavy magnesium water decomposition, and hydrothermal steps. The process first uses light-burning The powder is digested with water to generate a magnesium hydroxide slurry of

Hebei Messi Biology Co., Ltd. stated that among the existing processes for producing magnesium carbonate products, most of them are preparation processes for basic magnesium carbonate and hydrated magnesium carbonate. There are very few preparation methods for single-phase magnesium carbonate. Industrially The prepared anhydrous magnesium carbonate samples have different grain sizes, unsatisfactory purity, and complicated

Hebei Messi Biology Co., Ltd. stated that at present, flame retardants for polymer materials are developing in the direction of high efficiency, low smoke, and low toxicity. Therefore, the application of various halogen-free flame retardants and the research on their flame retardant mechanisms will become an important issue in the development of flame retardants. The
