Iron CAS#7439-89-6

Place small bags of iron powder in bags for food products, etc. or add iron powder to plastic bags. Using the principle of iron easy oxidation, its oxygen absorption function is applied to food preservation and preservative, which has a very significant effect.
Iron powder and ferrous salts are both food antioxidants and food nutrition enhancers. Iron deficiency is the most common nutritional deficiency in humans. As a consumption of natural minerals, iron is essential for human growth, development and daily work. Surveys show that about 12% of women aged 20 to 49 in the United States are deficient in iron, and 5% suffer from anemia. Anemia can impair a person’s cognitive abilities and immune function. To address iron deficiency, food producers often add iron flour to flour, corn, rice, breakfast cereals, and more. Yet, there is little research in countries around the world on the nutritional bioavailability of various iron powders added to food.
Iron powder is generally added in milk powder, and ferrous salt is added in soy sauce, vinegar and fruit juice drinks, the effect is very good, both can be antioxidant, but also can supplement iron, to prevent iron deficiency anemia. [1] Iron powder is used to produce powder metallurgy mechanical parts, its main physical properties are loose density, fluidity, formability, particle shape, etc., these properties are affected by the iron powder production method and its chemical composition.
(1) The application of hinge powder in the manufacture of powder metallurgy structural parts
The use of powder metallurgy method to manufacture mechanical parts has the advantages of saving materials and man-hours, easy to automate, easy to organize mass production, etc., which has attracted universal attention and has been developed. Iron-based powder metallurgy machinery parts in China’s automobiles, motorcycles, household appliances, power tools, office machinery, agricultural machinery, machine tools, instrumentation, textile machinery, metallurgical machinery and other industrial sectors have been used, and have achieved good technical and economic benefits.
(2) The application of iron powder in the production of welding rods, flame cutting and other aspects
Iron powder for welding rods, in the entire application of iron powder, occupies a certain proportion (Sweden accounts for 37%), generally in the electrode of the drug skin to add 10% to 30% of the iron powder can improve the welding process performance of the electrode.
Flame cutting and cleaning is another important aspect of iron powder applications. The United States uses about 7,000 tons of iron powder per year in this regard. When cutting refractory materials (such as concrete) with hydroxide flames or acetylene flames, adding iron powder to the flame can increase the flame temperature and also act as a co-solvent.
