In the process of calcination of activated magnesium oxide, the rate of temperature rise also has an effect on the activity of magnesium oxide, so it is very important to grasp the rate of temperature rise. The following experts from Hebei Meishen Technology Co., Ltd. introduced the relationship between the calcination temperature and activity of moderately active magnesium oxide.

　　In general, at a heating rate of 10 ° C / min, at each calcination temperature, the specific surface area and apparent specific volume of magnesium oxide are larger than the surface roughness of the magnesium oxide obtained at a heating rate of 5 ° C / min, at the same time, The citric acid activity values were all smaller than the magnesium oxide citrate activity values obtained at a heating rate of 5 ° C / min. Comparing the rate of change of each index at different temperatures, it is known that at low heating rates, the activity changes faster with the calcination temperature. Increasing the heating rate is beneficial to the improvement of magnesium oxide activity. After comprehensive consideration, it is preferred to select a heating rate of 8-10 ° C / min.

　　Therefore, Hebei Meishen Technology Co., Ltd. puts forward a proposal for customers who need magnesium oxide. In terms of magnesium oxide demand, customers with strict requirements for activity should choose a strong manufacturer when purchasing active magnesium oxide. After all, the production equipment and technology of the powerful manufacturers are relatively complete and advanced. The control of the activity in the process of calcination is also very mature. Only in this way can we find the suitable active magnesium oxide suitable for your product. Meishen company welcomes you to visit the factory and negotiate cooperation!
