The process flow for preparing pharmaceutical and food grade heavy magnesium carbonate from hydromagnesite is as follows: ① Raw material preparation: crush and screen the hydromagnesite to obtain magnesite powder with a particle size of 0.5-2mm. ② Calcination: Calculate magnesite powder at 800-900°C to obtain calcined magnesium oxide. ③ Water-soluble: Dissolve the calcined magnesium oxide
Hebei Messi Biology Co., Ltd. stated that magnesium oxide activity testing is the first step in production and is also a very important link. During the production process, why is it necessary to test the activity of magnesium oxide? There are two main reasons: Due to differences in ore grade, calcination process, and calcination temperature,

Magnesium carbonate whiskers are an inorganic material with excellent flame retardant properties. Its flame retardant performance mainly comes from the following two aspects: Magnesium carbonate whiskers have high thermal stability and decompose at high temperatures to release carbon dioxide and water vapor, forming a heat insulation layer to prevent heat transfer and inhibit the spread
Hebei Messi Biology Co., Ltd. stated that BMC material is the abbreviation of Bulk Molding Compounds, which is bulk molding compound. It is often called unsaturated polyester bulk molding compound in China. Its main raw materials are GF (chopped glass fiber), UP (unsaturated resin), MD (filler) and various additives that are fully mixed into a
