The use of magnesium powder is mainly used for fireworks, welding rod, steel desulfurization.
The standard finished product of magnesium powder is not more than 120t per batch.
Magnesium powder is the powder state of elemental magnesium. After the obtained magnesium powder particle size sample is fully mixed, 10-20g is taken to determine the particle size, and the mixed magnesium powder test sample is divided into 200g and sent to the laboratory for analysis.
Magnesium powder is inflammable and explosive, and produces high temperature and dazzling white light when burning. So magnesium powder has a wide range of uses in the field of science and technology such as military industry and aerospace industry. Magnesium powder is used for rocket ramjet engine and the removal of hydrogen chloride in propellant gas. If there is any unqualified or abnormal chemical composition in the test result of magnesium powder standard, double quantity of magnesium powder samples should be taken from the same batch of magnesium powder products for retest. The retest result of magnesium powder standard shall be the final test result of this batch of magnesium powder products.
. Magnesium powder is also used in aviation, aerospace, military, automobile, petroleum, chemical, pharmaceutical, smelting and other industries. The use of magnesium powder can also be used in steelmaking industry and non-ferrous metal casting, with magnesium powder as desulfurizer, cleaning agent, in the production of rare metals as reducing agent. Samples for standard determination of the size of magnesium powder should be sampled before batch, and samples for chemical analysis should be sampled after batch. Magnesium powder is dissolved in mineral acid, concentrated hydrofluoric acid, ammonium salt and hot water. Magnesium carbonate is very light and has a strong hygroscopic effect. Athletes use magnesium powder on their hands to increase the coefficient of friction. . It is mainly made of electrolytic melting magnesium chloride and electrolytic melting carnallite. Take one sample from each 20 small bags (25kg) and one sample from each large bag (1000kg) of magnesium powder.
In the chemical industry, the use of magnesium powder more and more, magnesium powder can be used as spray, coating, anticorrosion industry, in monocrystalline silicon, polysilicon and metallurgical powder die casting magnesium powder is also very large.
