Widely used in powder metallurgy, electric carbon products, electronic materials, metal coatings, chemical catalysts, filters, heat pipes and other electromechanical parts and electronic aviation fields.
Preparation：Usually electrolysis and atomization (water atomization and gas atomization).
Chemical nature：Copper can only be heated into CuO in an alcohol lamp, and it is difficult to be oxidized in dry air, but it is easily oxidized in humid air to form basic copper carbonate (2Cu+O2+H2O+CO2==Cu2(OH) ) 2CO3). Compared with copper flakes, copper powder is more likely to be oxidized because the surface is more in contact with air.
Copper can burn in chlorine to produce brownish-yellow smoke and produce copper chloride (Cu+Cl2=ignition=CuCl2).
Incompatible materials: strong acid, strong oxidant, halogen.
Skin contact: Take off contaminated clothing and rinse with plenty of running water.
Eye contact: Lift the eyelid and rinse with running water or saline. Seek medical attention.
Inhalation: Leave the scene quickly to a place with fresh air. If breathing is difficult, give oxygen. Seek medical attention.
Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.
Hazardous characteristics: The powder can burn in high temperature and open flame.
Hazardous combustion products: copper oxide.
Fire fighting method: Move the container from the fire scene to an open place as much as possible. Extinguishing agent: dry powder, sandy soil.
Emergency treatment: Isolate the leaking contaminated area and restrict access. Cut off the fire source. It is recommended that emergency personnel wear dust masks (full face masks) and general work clothes. Use a clean shovel to collect in a dry, clean, covered container. If there is a large amount of leakage, collect and recycle.
Part VII: Handling and storage
Operation precautions: Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks and chemical safety glasses. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid contact with oxidants, acids, halogens. Lightly load and unload during transportation to prevent damage to the package. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidants, acids, and halogens, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with suitable materials to contain the leakage.
