Lets learn about the synthesis and storage of iron powder!


Water-atomized pure iron powder is generally referred to as a sub-sieve powder that can pass through a 325 mesh sieve, that is, the particle size is less than 44 μm. To stop high-precision sieving, you can only use airflow classification equipment. It can only be done with JZDF nitrogen maintenance classifier. Iron powder mainly includes reconstituted iron powder and atomized iron powder, which are named because of different consumption methods.

Synthetic method

Polyaluminum sulfate liquid, the dilute sulfuric acid concentration of about 3% into the ferrous sulfate, and then participate in the ratio of sodium nitrite to ferrous phosphate about 3: 100, air or oxygen to stop oxidation, hydrolysis, polymerization reaction Polymeric ferric sulfate.

Manufacturing method of polymer ferric sulfate solid product:

Using liquid ferrous iron as the raw material, the air is used as the oxidant. After low-temperature dehydration, pulverization, high-temperature oxidation, please cool, telomerize, solidify, age, and pulverize to waste.

Handling and storage

Note on operation: closed operation, partial exhaust. The operators have been trained to strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety protective glasses, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from flammable and combustible materials. Prevent dust generation. Prevent contact with alkalis and alcohols. Pay particular attention to preventing contact with water. Handle lightly during handling to avoid damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage Precautions: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The package is sealed and must not get wet. It should be stored separately from flammable (combustible) materials, alkalis, alcohols, etc. Avoid mixed storage. Not for long, lest it change. The storage area should be provided with appropriate information to contain leaks.
