Magnesium alloys are alloys based on magnesium with the addition of other elements. Its characteristics are: low density (about 1.8 g/cm), high strength, large elastic modulus, good heat dissipation, good shock absorption, larger impact load capacity than aluminum alloy, and good corrosion resistance to organic matter and alkali. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. The most widely used is magnesium aluminum alloy, followed by magnesium manganese alloy and magnesium zinc zirconium alloy. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors.

Hazard to Breathing

Long-term inhalation of dust containing metal powder, susceptible to metal dust deposition. Some metals (such as iron, tin, antimony, barium, etc.) and their compounds dust induced pulmonary fibrosis is weak. Long-term inhalation of these dust, phagocytosis of metal and its compound particles of macrophages in the lung terminal bronchioles and the surrounding alveolar cavity aggregation, the formation of macrophage inflammation, not easy to lead to pulmonary fibrosis, normal or slightly damaged lung function, from the chest image abnormalities after exposure is usually reversible, can be partially or fully absorbed.

How to strengthen personal respiratory protection

First of all, look at the national standards. According to the GB2626-2019 standards for respiratory protection products published by the State Bureau of quality supervision, inspection and Quarantine and the State Standardization Management Committee, the units producing dust masks must obtain production and operation licenses according to law, and the production technical specifications of all dust masks must meet the corresponding standards. The standard specifies the production and technical specifications of respiratory protective equipment, and has strict regulations on the material, structure, performance, filtration efficiency, appearance, breathing resistance, detection methods, product identification, packaging, etc. of dust masks, and the materials must be skin Non-irritating, non-allergic, and the filter material is harmless to the human body; the structure of the dust mask should be convenient to use.
