At present, magnesium carbonate can be divided into many kinds according to its physicochemical properties and application industries. Because of its wide range of USES, its role varies from industry to industry. The following is a brief introduction to the application of magnesium carbonate in different industries.
- 1.Application in agriculture. Used to neutralize acidity in soil. Because long-term use of fertilizers such as urea can easily lead to acidic soil, magnesium carbonate can be directly added to urea to keep the soil at an appropriate pH value. Generally, it can increase crop yield by 15% ~ 40%, and also improve herbicide efficacy. Herbicide efficacy is the best when pH is 6.0-6.2. Magnesium carbonate can also compensate for the loss of magnesium content in the soil. Dolomite particles of 1.2-0.8um can flow freely. The filler used as fertilizer can improve the conditions for plants to utilize soil nutrients, reduce agglomeration, and facilitate the regulation of fertilizer ratio.
- Application of livestock and poultry feed. Calcium and magnesium are essential nutrients in animal body. Adding appropriate amount of magnesium carbonate (or 0.1 ~ 1.5mm particles) in animal and poultry feed is very beneficial for promoting animal growth and development and reducing diseases. It should be noted that the content of harmful elements must be strictly controlled in the development and utilization of forage grade magnesium carbonate.
- Application in paint and coating. Magnesium carbonate through the common water separation, drying, crushing, grinding, grading and other processes, and then after rinsing, chemical treatment, PH value adjustment, surface treatment and other processes, the production of new body pigment. Its chemical composition is stable, weather resistance, anti – sinking, fine powder, high whiteness, easy to disperse, low cost, unique technology and many other advantages, can be used for a variety of paint. The coating produced can reduce the amount of titanium dioxide, feel good, flu, hardness, strong adhesion and other characteristics, the application effect is better than heavy calcium carbonate.
- Application in environmental protection. Magnesium carbonate can be used to improve dust flying in coal mine, prevent and delay coal dust explosion. Dolomite powder is used as filtration material for water treatment, especially for neutralization from drinking water to industrial water and swimming pool water, as well as for iron, manganese and silicate removal.
