Iron powder food grade, gray or black powder, also known as "double absorbent", can absorb air moisture and oxygen, often used for food preservation. The iron powder food grade is generally formed by the reduction of iron trioxide in hydrogen flow or carbon monoxide flow under high heat conditions. The main component is the loose structure of simple iron. Since the iron powder food grade itself is powdered and its microstructure is very loose, its surface is active. It is often used as high quality reductant in chemical production and laboratory operation.
1. As the raw material of powder metallurgy products, the consumption is about 60% of the total consumption of iron powder food grade.
2. As the raw material of electrode the addition of 10% 70% iron powder food grade into the coating can improve the welding process and improve the deposition efficiency.
3. As the spraying agent for flame cutting , when the steel product is cut , the iron powder is injected into the oxygen - acetylene flame , the cutting performance can be improved , the range of the cutting steel can be enlarged .
4.It can also be used as reducing agent in organic chemical synthesis, printing ink carrier and so on.
Iron powder food grade should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
