Information

There are many indicators of Magnesium Oxide MgO. In the tire industry, if the moisture content is high, it will cause problems such as blisters and trachoma in the tire.

The crystallization water contained in Magnesium Oxide MgO itself will not affect the use of the product, and the external water will affect the use of the product, mainly due to damp or wet. Generally, the moisture content of light Magnesium Oxide MgO below 1.5% will not affect the quality of the product. The moisture contained in Magnesium Oxide MgO itself is crystal water, and no more than 1.5% will not affect the use. Crystal water and damp water are different. .

The boiling point of water is 100 degrees, and the water will start to evaporate above 100 degrees. The temperature of Magnesium Oxide MgO is generally between 650-850 during calcination, and the water has already evaporated. Therefore, most of the causes of excessive moisture are damp, wet during transportation or long-term storage during use due to damp and agglomeration, and the moisture will be higher than 1.5%. If the moisture is high, it means that Magnesium Oxide MgO is damp, and a part of Magnesium Oxide MgO absorbs carbon dioxide and water in the air to form basic magnesium carbonate, so the content of Magnesium Oxide MgO decreases.
