What Should You Notice During Production of Magnesium Oxide in Summer?

   In summer, it should notice more issues during the production of magnesium oxide. Now, there is a professional magnesium oxide manufacturer and supplier named Meishen Technology. It lists some aspects for you:
   In the first aspect, the saw dust, coal ash and other paddings should remain dry to the greatest extent.
   If the magnesium oxide become excessive moistening, it amounts to reduce concentration of bittern, the product would have insufficient strength. In addition, after adding magnesium powder, adding coal ash and other inorganic fillers into brine. The best quality saw dust is pine(the low water absorption). So, it should be add into slurry in the end. If you add it into brine in advance, it would adsorb brine in abundance and lead the incomplete reaction of brine. At the same time, the dispersion of modifying agent will be effected.
   In summer, the brine should be controlled between 23 and 25 baume degree. Otherwise, the product is easy to active magnesia if too high. Or product strength the can not achieve requirement if the baume degree is too low.
   In the second aspect, dynamic matching.
   The dynamic matching mainly refer to the molar ratio between magnesium oxide and magnesium chloride. Generally speaking, the molar ratio between them should be greater than six. (the magnesium oxide powder remains excess a little. Because not all the magnesium oxide powder can completely react with brine.)
   Take a customer from Hebei as an example, the previous materials proportion of this customer is: 100 kilograms of magnesium oxide, active is 65%, 115 kilograms of brine, 25 baume degrees, the molar ratio between magnesium oxide and magnesium chloride is 6.21. This proportion is reasonable. However, because there is more rain in summer, the magnesium oxide activity is decreasing continually. As thus, it demands that the dosage of brine should be reduced accordingly. If you still use the same formula, it would be go wrong.
   In the third aspect: the storage of magnesium oxide.
   The magnesium belongs to the second main group. The chemical property is close to calcium, which is one of the congeners. Magnesium oxide has similar chemical properties with calcium oxide. It is easy to generate magnesium salt through reacting with water. Therefore, the storage of magnesium oxide should stay as dry as possible. For the detail, you can pave some slag or put some drying agent. The more important is to store separate with magnesium chloride(Because the magnesium chloride is strong moisture absorption agent, it will increase the relative humidity of the environment).
   In the fourth aspect, the additive amount of modifying agent.
   In summer, the temperature is higher, you should properly increase the additive amount of modifying agent. It can put off the heat release obviously, prevent deformation of panel and others. At the same time, it can improve the products hydrolytic resistance.
   The above introductions is from a professional magnesium oxide supplier and manufacturer.
