Advantages of Magnesium Steel Grade Magnesium Oxide from Messi Biology

Magnesium steel grade magnesium oxide is a white powder with small particle size, good water suspension, low hydration rate and a certain particle size distribution range. Silicon steel grade magnesium oxide is mainly used to produce oriented silicon steel sheets. Its main function is to react with magnesium oxide and silicon steel sheets under high temperature to form a thin film. This film is arranged in an orderly manner and can reduce the reactive power loss of silicon steel sheets during operation. Silicon steel magnesium oxide is a high-temperature annealing isolation agent in the production of oriented silicon steel sheets. Transformer materials made of oriented silicon steel sheets have the special function of high energy saving. High-tech industries such as aircraft turbines and chips in mobile phones are all made of oriented silicon steel sheets. There is a broad development prospect and space in these fields.

magnesium oxide

The silicon steel grade magnesium oxide produced by Hebei Messi Biology Co., Ltd., a national high-tech enterprise, has obtained a national patent and can completely replace Japanese imported products, ranking among the top in the global industry. Hebei Messi Biology Co., Ltd.can improve the automation level of the production process by controlling the water used for hydration and improving the drying process. On the premise of ensuring that important indicators such as hydration rate do not change, the viscosity of silicon steel grade magnesium oxide is improved.

Hebei Messi Biology Co., Ltd. has optimized the analytical conditions of silicon steel grade magnesium oxide measured by laser particle size analyzer, such as dispersion medium, dispersion method, sample pretreatment, instrument dimness, etc., and explored a test method with good reproducibility in measuring the particle size range of silicon steel grade magnesium oxide, which meets the requirements of silicon steel production process control for magnesium oxide particle size.

A method for preparing high-viscosity silicon steel grade magnesium oxide, comprising the following steps:

(a) putting magnesium oxide powder and surfactant into a reactor, and adding active water for hydration reaction, the hydration reaction temperature is 80-90°C, and the hydration reaction time is 1-2 hours;

(b) separating, washing and drying the product after the hydration reaction in step a to obtain magnesium hydroxide;

(c) putting the magnesium hydroxide obtained in step b into a high-temperature converter, calcining by dynamic calcination method, the calcination temperature is 900-980°C, the calcination time is 2-4 hours, obtaining magnesium oxide particles, and crushing and grading to obtain high-viscosity silicon steel grade magnesium oxide.
