Magnesium oxide can improve the chemical stability and mechanical strength of the glass, and can reduce the crystallization tendency of the glass. If magnesium oxide is used instead of calcium oxide, it can reduce the crystal disappearance temperature, reduce the devitrification tendency and crystallization speed of the glass, and also have a positive effect on […]

Hebei Messi Biology Co., Ltd. stated that magnesium carbonate is an important inorganic chemical material with good filling, dispersibility and flame retardancy. Adding it to engineering plastics can significantly improve the flame retardancy of engineering plastics. At the same time, it can also be used as refractory materials, insulation materials for boilers and pipelines, and

I. The necessity of adding magnesium hydroxide flame retardant in soft PVC Polyvinyl chloride (PVC) is a common chemical material, usually divided into two kinds of rigid PVC and soft PVC. Rigid PVC has a certain degree of self-extinguishing, while soft PVC due to the addition of many plasticizers to increase its plasticity and processing

Phosphor is in the ultraviolet, visible radiation and electric field caused by the action of luminescent substances, mainly used in certain electric light sources, generally refers to the mercury vapor discharge of ultraviolet radiation produced when converted to visible light or the desired wavelength of ultraviolet light-emitting substances (traditional fluorescent lamps, energy-saving lamps). But the

Magnesium oxide is generally divided into light magnesium oxide and heavy magnesium oxide two kinds, light volume fluffy, white amorphous powder, odorless, tasteless and non-toxic, density 3.58g/cm3, insoluble in pure water and organic solvents, solubility in water due to the presence of carbon dioxide and increase, can be dissolved in acid, ammonium salt solution. Scorched

Reactive magnesia, also known as light-burned magnesia or caustic magnesia, is magnesia formed by calcining magnesium compounds below 900°C. The chemical activity of magnesia can be expressed by iodine absorption value (adsorption performance index). The higher the iodine value, the lighter it is. When the iodine absorption value is 120-180mg/g, it is called high-activity magnesia;
Magnesium oxide is widely used and can be seen everywhere in our basic necessities of life. Today I will talk about the application of food and pharmaceutical grade magnesium oxide in the cosmetics industry. Magnesium oxide is used in the production process of many cosmetics and skin care products (such as sunscreen, loose powder, mask,

With the improvement of environmental protection requirements, the inorganic flame retardant magnesium hydroxide has attracted the attention of various countries. Various developed countries have invested a lot of money in the research and development of magnesium hydroxide flame retardants. In addition to general-purpose varieties, various special-purpose and compound-type new products emerge in an endless stream,
Magnesium oxide is a high-performance chemical material with excellent chemical inertness, heat resistance, insulation and thermal conductivity. Especially its good high temperature oxidation resistance and moderate alkalinity make it widely used in many fields. In addition, the oxygen vacancies and single electrons in magnesium oxide also endow it with strong electrophilicity, which provides an important
