Magnesium oxide price, how much is a ton of magnesium oxide? What we usually call the effective content of white ash refers to the content of calcium oxide (CAO) light calcined powder and magnesium oxide (MGO) contained in the white ash, these two kinds of light calcined powder The substance plays a decisive role in the strength of the limestone base, especially after the hydration reaction with fly ash, the effect of its content is more significant. Increasing the lime dosage to a certain extent can naturally increase the limestone. The strength of the crushed stone, but this not only increases the construction cost, but also is very unfavorable to improve the crack resistance of the limestone base. Therefore, the lime with high effective content should be selected as much as possible. The standard, that is, the content of available calcium and magnesium oxide in the white ash is not less than 80%, which can not only meet the needs of the oxidation and hydration molding of the limestone base, ensure the strength of the base, but also improve the stability of the base, without affecting its Crack resistance is very beneficial to ensure the quality of the base layer. The price of magnesium oxide, how much is a ton of magnesium oxide? The digestion of quicklime is an important link in the construction and mixing, and its process should be effectively controlled in the specific construction. The digestion of quicklime is actually a CAO (MGO) hydration ( H2O) exothermic reaction process, it is necessary to correctly control the amount of water and the speed of adding water, so that the digested slaked lime can not be too dry and "dust", nor too wet and "softened", and the surface looks loose. The water content should not exceed 35%, in order to facilitate the uniform mixing of the limestone mixture. In actual construction, the methods of pre-digestion, piling, covering, and sieving are usually used to meet the construction needs (the time for pre-digestion is generally 7 -10 days).

One of the main uses of magnesium oxide is as a flame retardant. Traditional flame retardant materials, such as good magnesium oxide, are widely used in flame retardant mixtures composed of halogen-containing polymers or halogen-containing flame retardants. However, once a fire occurs, due to thermal decomposition and combustion, a large amount of smoke and toxic corrosive gases will be generated, which will hinder fire fighting and evacuation of personnel, and corrode instruments and equipment. In particular, it has been found that more than 80% of the fatal accidents in fires are caused by the thick smoke and toxic gases produced by the material. Therefore, in addition to the flame retardant efficiency, magnesium oxide, low smoke and low toxicity are also essential indicators of flame retardants. The development of China's flame retardant industry is extremely unbalanced, and chlorine-based flame retardants account for a relatively large proportion, ranking first among all flame retardants. However, when chlorine-based flame retardants act, they release toxic gases, which are far from what modern life pursues. Therefore, in order to comply with the development trend of low smoke, low toxicity and pollution-free flame retardants in the world, the development, production and application of magnesium oxide flame retardants are imperative.
