How to check whether feed magnesium oxide has metamorphosed and expired

Strictly speaking, dropping magnesium beyond the shelf life can affect the activity of magnesium oxide itself. However, despite the large inventory, giving up and worrying about causing damage. Currently, we report that you can check whether it can still be manipulated from the following aspects. Feed magnesium oxide

Initially, a preliminary examination was conducted. Under normal circumstances, magnesium oxide should be a white powder. If magnesium oxide undergoes changes, the complexion will change. In addition, the whiteness of magnesium oxide is low, and it is also known that the activity of magnesium oxide has changed. Other phenomena of magnesium oxide, if they can be observed to have significant changes (agglomerations, etc.), are inherently uneven, and are generally not considered for use

Next, check the storage terms of magnesium oxide: Magnesium oxide is an extremely simple substance that absorbs water and is affected by moisture. If you do not do a good job of moisture-proof during storage or transportation, it may cause magnesium oxide to denature and lose its use cost. In normal operations, you can follow the following route to build magnesium oxide to prevent water absorption and degeneration. 1. Cover it with plastic film, and cover it with plastic film on the ground. If you are unwilling to replace the bags with packaging, you can choose this gradual moisture-proof method; Placing lime blocks after stacking to prevent moisture is another way to avoid magnesium oxide moisture absorption and decrease activity; Because calcium oxide has stronger moisture absorption, placing calcium oxide in hotels as a moisture reducing agent to reduce humidity in warehouses is very effective;

Is it clear how long magnesium oxide has exceeded its shelf life: how long will the storage time and outcome of magnesium oxide be? Beyond the shelf life of one or two months, and beyond the shelf life of one or two years is bound to be a big difference. Secondly, where is magnesium oxide used? Is it important to use magnesium oxide as a commodity? If a seizure occurs, will it result in greater loss? Generally speaking, if there is no significant change in the surface of magnesium oxide, we advocate a new inspection of the activity of magnesium oxide. After specialized inspection equipment, magnesium oxide inspection can quantitatively and thoroughly determine the activity of magnesium oxide. It is guaranteed that the activity will not decrease due to too long storage time, resulting in misuse, and then affecting the quality of the products produced

The main point is that we hope to be able to use it within the shelf life. Otherwise, poor maintenance will affect its activity and spoil the purchased magnesium oxide. We hope that we can all use high-quality magnesium oxide
