At the beginning, the initial inspection was carried out. Under normal circumstances, magnesium oxide should be a white powder. If magnesium oxide bursts, the face will change. In addition, the whiteness of magnesium oxide is low, and it is understood that the activity of magnesium oxide has changed. In addition, if the phenomenon of magnesium oxide can be observed with obvious changes (caking, etc.), the nature is uneven, and it is usually not used.

Then check the storage terms of magnesium oxide: magnesium oxide is an extremely simple substance that absorbs moisture and moisture.If you are afraid of not doing the homework for moisture protection during transportation, it may cause the degeneration of magnesium oxide and lose the cost of use. In the operation, the following routes can be used to build magnesium oxide to stop the transformation of water absorption. 1. Cover the plastic film and spread the plastic film on the ground.If you are unwilling to change the bag and change the packaging, you can choose this to gradually prevent moisture. Moisture-proof, this is another way to avoid magnesium oxide moisture absorption and avoid reducing activity; 3, because calcium oxide has stronger moisture absorption, place calcium oxide in the hotel and use it as a moisture-reducing agent to reduce the humidity of the warehouse , Very effective;

Ultimately, it is clear how long the magnesium oxide exceeds the shelf life: how long does the storage time of magnesium oxide end? The shelf life of one or two months beyond the shelf life, and the one or two years beyond the shelf life are destined to be very big. The second is where is the magnesium oxide used? Is the product of magnesium oxide important? If there is a problem, will there be a large loss? In general, if there is no significant change in the surface of magnesium oxide, we suggest that it is best to check the activity of magnesium oxide again. The inspection can be quantitatively and thoroughly determined by the inspection equipment of the specialty. It is guaranteed that the activity will not be reduced or misused due to the placement time is too long, and then the quality of the manufactured goods will be affected.

The most important point is that Bawang can be used up within the shelf life, otherwise, if it is left behind, no matter how good the maintenance is, it will affect its activity, and it will spoil the purchased magnesium oxide.
