The clinker particles in the kiln are formed under the action of the liquid phase (some materials called melt), and the liquid phase forms a capillary bridge outside the crystal. For light-burned magnesia powder, the liquid phase capillary bridge plays two roles: one is to bind the particles together, and the other is to act as an intermediate medium to diffuse CaO and C2S in the molten state to form C3S. The strength of the particles depends on the capillary bridge The strength of the bridge, the strength of the connecting particles, increases with the increase of the surface tension of the liquid phase and the decrease of the particle diameter. The number of light burned powder capillary bridges is inversely proportional to the square root of the particle diameter. To make good granules, there must be enough liquid phase, and the particles are required to be evenly distributed in the liquid phase, forming higher surface tension, lower liquid phase viscosity, and suitable granulation time and temperature.

First of all, magnesium oxide itself is non-toxic and tasteless, but because it belongs to dust, front-line workers should pay attention to dust during long-term work to avoid "pulmonary disease". In addition, magnesium oxide powder and talcum powder are commonly used lubricants for athletes and are harmless to the human body. Magnesium oxide can also be used as an antacid, a laxative, to neutralize gastric acid, and the effect of neutralizing gastric acid is faster, stronger, and lasting, without producing carbon dioxide, and protecting the ulcer surface.

Light burnt magnesia powder wholesale

Recently, through user surveys on the production of fireproof panels, many customers do not pay attention to the content of light burned magnesia powder and the activity of magnesium oxide in order to reduce production costs when making fireproof panels. They think that any content of magnesium oxide is fine, especially in summer. Not paying attention to the content of magnesium oxide directly causes the product to solidify slowly, and the manufactured product has no tension or toughness. It is hoped that the majority of fireproof board users can use high-content and high-activity light-burned magnesia powder in summer to eliminate the objectivity problems such as the lack of hardness of the product.

Recommended content of magnesium oxide for fireproof board: 80%, 85% content. The content of iron trioxide should be kept low, because the fireproof board requires more white color.
