Do you know what are the uses of magnesium hydroxide?
Magnesium hydroxide is widely used as a flame retardant filler for plastics, resins, rubbers, paints and other materials, as well as an antacid for treating hyperacidity, a neutralizer for acid-containing wastewater, a desulfurizer, a laxative, a deodorant, etc. In addition, it is also used in the electronics industry, medicine, sugar refining and the preparation of other magnesium compounds (such as magnesium sulfate and magnesium oxide).
The properties of Magnesium hydroxide Flame retardant are:
It decomposes above 340°C to generate magnesium oxide and water, absorbing the heat on the surface of the combustible. The generation of a large amount of water has the effect of diluting and isolating the air (oxygen) on the surface of the combustible, and the activated magnesium oxide solid generated by the decomposition is a high-temperature resistant substance, which adheres to the surface of the combustible to further prevent the combustion from proceeding.
Magnesium hydroxide does not produce corrosive and toxic gases when decomposed, and it is alkaline, which can absorb and neutralize the acid gases released during combustion, such as carbon dioxide, sulfur dioxide and nitrogen oxides, and the activated magnesium oxide generated by decomposition can also absorb The harmful gas, smoke and incompletely burned melting residue produced can eliminate the smoke and stop the generation of molten droplets, so as to achieve the purpose of flame retardancy.
Magnesium hydroxide is used as a deodorant:
Because it is abundant in nature and its chemical properties are similar to aluminum, magnesium hydroxide has been used in the market to replace aluminum chloride in fragrance products in recent years.
Environmental protection industry:
Magnesium hydroxide has a great effect on environmental protection. It can not only be used as a neutralizer, but also has very strong adsorption, and has been widely used in acid waste or wastewater. And its cost is relatively low, greatly improving work efficiency.
Industry:
Magnesium hydroxide is often seen in industrial industries. For example, the ceramic industry, paint and coating industry will use this chemical substance. It can not only increase the wear resistance and lower the melting point, but also make the metal lattice more compact. Therefore, the quality of the produced products will be higher and more suitable for the needs of modern people.
Oil additive:
Magnesium hydroxide can also be used as an oil additive. In the industry, its anti-corrosion performance and desulfurization are mainly used.
