Application in desulfurization  

  • High desulfurization efficiency: Magnesium oxide is much larger than the calcium-based desulfurizer in terms of chemical reactivity, and the molecular weight of magnesium oxide is smaller than that of calcium carbonate and calcium oxide. Therefore, the desulfurization efficiency of magnesium oxide is higher than that of the calcium method under the same conditions. Under normal circumstances, the desulfurization efficiency of magnesium oxide can reach above 95-98%, while the desulfurization efficiency of limestone/gypsum method is only about 90-95%.
  • Low investment cost: Since magnesium oxide has its unique superiority as desulfurization itself, the structural design, the amount of circulating slurry, the overall scale of the system, and the power of the equipment can be correspondingly small, so that the entire desulfurization system The investment cost can be reduced by more than 20%.
  • Low operating costs: The main factors determining the operating costs of the desulfurization system are the consumption of desulfurizers and the cost of water and electricity. The price of magnesium oxide is higher than that of calcium oxide, but the amount of SO2 magnesia removed is 40% of calcium carbonate. The ratio of liquid to gas is a very important factor in terms of power consumption such as water and electricity. It is directly related to Desulfurization efficiency of the entire system and operating costs of the system. For the limestone gypsum system, the liquid-to-gas ratio is generally above 15 L/m3, and the magnesium oxide is below 7 L/m3, so that the magnesia desulfurization process can save a large part of the cost. At the same time, the sale of by-products of magnesium oxide can offset a large part of the cost.
  • Reliable operation: The biggest advantage of magnesium desulfurization relative to calcium method is that the system does not have the problem of equipment fouling and blockage, which can ensure the safe and effective operation of the whole desulfurization system. At the same time, the pH value of magnesium method is controlled between 6.0 and 6.5. The corrosion problem of equipment under certain conditions has also been solved to some extent. In general, magnesium desulfurization has a very strong guarantee for the safety performance in practical engineering.

 

Application in Rubber 

  • Magnesium oxide in nitrile rubber can do heat-resistant rubber reinforcing agent. Adding the right amount of magnesium oxide in chloroprene rubber vulcanized rubber can improve the tensile strength, tensile stress and hardness, and can neutralize a small amount of hydrogen chloride during vulcanization or products produced in the sunlight, but the heat resistance is slightly worse.
  • Magnesium oxide added during the mixing process can prevent the production of coke burning, and improve the rubber in the storage process of coke burning, can prevent the early cross-linking and cyclization of neoprene, can increase the safety of operation. And when mastication, also has the effect of plasticizing rubber. In the curing time and become vulcanizing machine, play the role of hydrogen chloride acceptor, improve the rubber force, prevent the erosion of hydrogen chloride on the fibrous tissue.
  • In the rubber containing halogen can be used as acid absorbent. In the composite material inside as a thickener. In halogenated butyl rubber can be used as vulcanizing agent and filler. In addition there are improved rubber magnesia temperature rating, increase the adhesion properties of the metal skeleton, improve the mixing of the package roll; absorption of heat decomposition of free halogen these effects.

Application in Tires  

The use of magnesium oxide is very wide, it can be used in tire special magnesium oxide, medical stopper special magnesium oxide, adhesive special magnesium oxide network and other fields, from the anti-scorch agent, vulcanization accelerator, acid absorption agent (halogenated butyl rubber in the curing process will release hydrogen chloride), fillers, high temperature, fire retardant, wear resistance, corrosion resistance.

 

 Application in The Manufacture Of Papermaking Slurry  

Production of magnesium oxide instead of ammonia applied to the role of ammonium sulfite pulp. The results show that the basic buffers are magnesia, and the indexes of slurry can reach the same level as that of ammonia.

The magnesium oxide as a buffer, the pulp is easy to bleach, can promote the steaming process delignification effect, reduce emissions, help protect the environment, but also can reduce costs. Pulp bleaching effect can be applied magnesium hydroxide. Compared with the traditional bleaching process, magnesium hydroxide can replace caustic soda, while magnesium hydroxide can improve the viscosity of the slurry to maintain the brightness of the pulp, and reduce the content of COD and production costs.

In the process of hydrogen peroxide bleaching pulp, magnesium oxide or magnesium hydroxide can replace caustic soda, play a role in reducing the iron in the slurry. Manganeseion content, but also to avoid the presence of excess iron and yellow, improve the quality of the slurry. At the same time, magnesium oxide and magnesium hydroxide has a buffering effect, and easy to control the pH value.

If with phosphates, silicates and other inorganic complexing agent with the use of the effect will be better. Magnesia can act as a wetting agent to improve pulp deinking operations. Traditional sulfite pulping process to improve the magnesium agent sulfite slurry process, after the improvement can take advantage of lower quality wood as a raw material to produce pulp can be used in the manufacture of press printing paper, and the use of agents and waste heat can be recycled. In this way, the paper mill to solve the traditional sulfite pulp operations in many ecological and economic issues.

 

Application in Dyes  

Magnesium oxide used in dyes and dye intermediates, the catalytic effect is significant, effectively adjust the PH value concentration, used in products to improve the color of light, bright color products, improve product quality. Magnesia in the dye mainly play the role of filler. Some products for the whiteness of the existence of the requirements, but there are heavy color products on the color of magnesium oxide requirements are not too strict. Secondly, the content of impurities to be less than 325 mesh sieve residue 0.01.

 

Application in Agriculture  

Agriculture is an important market for magnesium oxide. Magnesium is an essential nutrient for plant photosynthesis and animal health. Caustic calcined magnesia is the most common type of animal feed due to its high magnesium concentration and bioavailability. Crops such as citrus, potatoes, vegetables, fruits and grass require magnesium-rich fertilizers for optimal yields, and caustic calcined magnesia is the most popular type.

 

Application in High-Tech 

High temperature resistant materials and high temperature resistant optical materials used in the field of aviation, aerospace industry, is made of high purity fused magnesia crystal, because of high purity fused magnesia crystal has good high temperature resistance and light transmission. The basic raw material of uranium purification and smelting of the nuclear industry, are inseparable from magnesium oxide, uranium beneficiation purification process to adjust the pH value, light magnesium oxide is the preferred material. Uranium smelting furnace is the use of high-purity fused magnesia crystal of high temperature resistance and thermal stability and other manufacturing characteristics.
