Types of zinc oxide
Classification: divided into light magnesium oxide and heavy magnesium oxide. Light magnesium oxide has loose volume and is a white amorphous powder. Odorless, tasteless and non-toxic. Density 3.58g/cm3. Insoluble in pure water and organic solvents, the solubility in water increases due to the presence of carbon dioxide. Soluble in acid and ammonium salt solutions. Converted into crystals after high-temperature burning. Magnesium carbonate complex salt is generated when it encounters carbon dioxide in the air. Heavy magnesium oxide has a compact volume and is a white or beige powder. It is easy to combine with water and absorb moisture and carbon dioxide when exposed to air. It is easy to gel and harden when mixed with magnesium chloride solution.
With the upgrading of industrialization and the demand and development of the high-tech functional materials market, a series of high-tech fine magnesium oxide products have been developed and produced, mainly used in advanced lubricating oils, advanced tanning leather alkali grade, food grade, medicine, silicon steel grade, advanced electromagnetic grade, high-purity magnesium oxide and nearly ten other varieties.
Advanced lubricant grade
Application areas: Mainly used as a detergent, vanadium inhibitor, and desulfurizer in advanced lubricant processing, greatly improving the density and rheology of the lubricating film and reducing ash content. Removing lead and mercury reduces the pollution of lubricating oil or fuel waste to the environment. The surface-treated magnesium oxide can also be used as a complexing agent, chelating agent, and carrier in the oil refining process, which is more conducive to product fractionation and improving product quality. In particular, adding Mg0 during heavy oil combustion can eliminate the damage of vanadic acid in heavy oil to the furnace.
Food grade
Application areas: Used as food additives, color stabilizers, pH regulators, and magnesium supplements for health products and foods. Used as a decolorizer for sugar refining, ice cream powder pH regulator, etc. It is used as an anti-caking agent and antacid in wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder, etc. It can also be used in the manufacture of ceramics, enamel, glass, dyes, etc.
Magnesium oxide can be produced through various methods, including the carbonation process, calcination of magnesium hydroxide, soda ash process, and ammonium bicarbonate process. The choice of method often depends on the specific needs and characteristics of downstream industries. For example, the carbonation process can produce lightweight magnesium oxide, while the calcination of magnesium hydroxide can produce high-purity magnesium oxide.
Magnesium oxide consists of Mg²⁺ ions and O²⁻ ions bound together through ionic bonds to form a crystal lattice. At high temperatures, magnesium oxide exhibits excellent physical and chemical stability, making it a model system for studying crystal vibration characteristics. Additionally, magnesium oxide is widely regarded as the most effective metal stabilizer compared to silicate cement, lime, and others due to its superior buffering capacity, cost-effectiveness, and ease/safety of operation.
Magnesium oxide enterprises should establish an application technology department with professional technical service personnel. These personnel should possess extensive knowledge and experience in production processes, technology, and magnesium oxide applications, enabling them to provide professional technical support and solutions to customers.
Magnesium oxide should be stored in a cool, well-ventilated warehouse, avoiding direct sunlight and high temperatures. The warehouse should be kept away from fire sources and heat to prevent magnesium oxide from undergoing chemical reactions or fires due to high temperatures. The packaging of magnesium oxide should be intact to prevent leakage, damage, or dropping during transportation. According to the HG/T 2573-2012 standard, the packaging of industrial light magnesium oxide must comply with specific regulations.
