With the industrialization upgrade and the demand and development of the high-tech functional material market, a series of high-tech fine magnesium oxide products have been developed and produced. Haicheng magnesium oxide is mainly used for advanced lubricating oil, advanced tanning and alkali extraction, food grade, medicine, It is composed of nearly ten varieties such as silicon steel grade, advanced electromagnetic grade, and high-purity magnesium oxide.

The application of light burning powder

Folding Application: Mainly used in the production of magnesite products. Light-burned magnesium oxide and magnesium chloride aqueous solution in a certain proportion can be gelatinized and hardened into a hardened body with certain physical and mechanical properties, which is called magnesite cement. As a new type of cement, magnesite cement has the advantages of light weight and high strength, fireproof and heat insulation, energy saving and environmental protection, and can be widely used in building materials, municipal administration, agriculture, machinery and other fields. According to the regulations of WB/T1019-2002 "Light-burned magnesia for magnesite products", the chemical composition of light-burned magnesia is shown in Table 1.

Application field: Mainly used as cleaning agent, vanadium inhibitor and desulfurizer in advanced lubricating oil processing, greatly improving the density and rheology of lubricating film and reducing ash content. The removal of lead and mercury can reduce the pollution of lubricating oil or fuel waste to the environment. Surface-treated magnesium oxide can also be used as a complexing agent, chelating agent and carrier in the refining process, which is more conducive to product fractionation to improve product quality. In particular, the addition of Mg0 during the combustion of heavy oil can eliminate the damage of vanadic acid in the heavy oil to the furnace.

food grade magnesium oxide

Application fields: used as food additives, color stabilizers, pH adjusters as supplements of magnesium in health products and food. It is used as a decolorizing agent in the refining of sugar, as a PH regulator for ice cream powder, etc. As an anti-caking agent and antacid, it can be used in the fields of 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 and other fields.

Medical Grade Magnesium Oxide

Application field: In the field of biopharmaceuticals, medical grade magnesium oxide can be used as antacid, adsorbent, desulfurizer, lead remover, complex filter aid, PH adjuster. In medicine, it can be used as antacid and laxative, inhibiting and relieving Hyperacidity, treatment of gastric and duodenal ulcers. The neutralizing effect of gastric acid is strong, slow and long-lasting, and does not produce carbon dioxide.

Silicon steel grade magnesium oxide

Application field: silicon steel grade magnesia has good magnetic permeability (that is, has a large positive magnetic susceptibility) and excellent insulating properties (that is, the electrical conductivity can be as low as 10-14us/cm dense state). It can form a good insulating layer and magnetic conductive medium on the surface of the silicon steel sheet to suppress and overcome the eddy current and skin effect loss (referred to as iron loss) of the silicon steel core in the transformer. Improve the insulating properties of silicon steel sheets, and be used as a high-temperature annealing separator. It can also be used as ceramic materials, electronic materials, chemical raw materials, binders, additives, etc. It can be used as dephosphorization agent, desulfurizer, and insulating coating generator in silicon steel.
