There are various raw material production routes for magnesium oxide enterprises in China, especially in the past decade. The dolomite carbonization method has achieved significant development, forming its own characteristics in processes, equipment, and other aspects. Technological achievements have constantly emerged and been applied in production practice. Magnesium containing calcium carbonate has been successfully prepared and applied, greatly solving the pollution problem caused by the dolomite carbonization method. Moreover, in recent years, traditional brine based magnesium salts have been developing towards high-purity, high added value, functional and functional products.
Light burned magnesium powder products include three types: under burned products, over burned products, and active magnesium oxide. Below, the editor will introduce the three states of magnesium oxide. Light burnt powder
The so-called undercooked products are some Magnesium carbonate that does not form magnesium oxide. If there are more undercooked products, the burning vector will be high. The setting speed of magnesite products made from light burned magnesite powder is particularly fast, which will lead to the bursting and deformation of magnesite products. 2. Overburnt products are burnt magnesium oxide. If there are many burnt products, it is not easy to solidify when it is used to produce oxy magnesium chloride cement with Magnesium chloride, which is what people often say, "no reflection, no condensation". 3. The last one is the industry of active magnesium oxide as building materials, which mainly requires the content of active magnesium oxide. If the content of active magnesium oxide is not enough, it cannot fully reflect the phenomenon of anti alkali and anti halogen after the molding of magnesite products with the chloride ion in Magnesium chloride.
Recently, through a survey of users who produce fire-resistant panels using light burned magnesium powder, many customers have found that in order to reduce production costs, they do not pay attention to the content of light burned magnesium powder and the activity of magnesium oxide, thinking that any amount of magnesium oxide can be used. Especially in summer, they do not pay attention to the content of magnesium oxide, which directly leads to slow product solidification and the resulting products lack tensile strength and toughness. We hope that the majority of fireproof board users can use high content and high activity light burned magnesium oxide powder in summer to eliminate objective issues such as product hardness.
