Due to its extremely high chemical activity and extremely flammable and explosive characteristics, diffuser powder (flash powder) must strictly comply with safety operation specifications during use and storage to ensure the safety of personnel and equipment. The following is a detailed explanation of the storage environment, operating precautions, emergency treatment and industrial applications.
1. Storage safety requirements
Sealed storage
Diffused powder should be stored in a dedicated sealed container to avoid direct contact with moisture and oxygen in the air. The container material should be non-metallic materials that are not easy to generate sparks or static electricity to prevent sparks caused by friction and cause fire or explosion.
Moisture-proof, waterproof, anti-oxidant
Moisture will cause diffuser powder to agglomerate or oxidize prematurely, reducing its performance and increasing safety hazards. Therefore, the storage environment should be kept dry and avoid exposure to humid air or near water sources. At the same time, it should be kept away from strong oxidants and other substances that may cause violent chemical reactions.
Temperature and environmental control
The storage area needs to maintain a constant temperature and avoid high temperatures or direct sunlight, because excessive temperatures will increase the activity of diffuser powder and increase the risk of combustion and explosion. The storage place should be equipped with firewalls and explosion-proof facilities to reduce the risk of accident spread.
2. Operation safety specifications
Prevent friction and impact
Diffuse powder is very easy to produce sparks due to mechanical friction or impact, so metal tools or hard utensils should be avoided during operation. Operators should wear anti-static clothing and gloves to prevent static electricity accumulation and spark discharge.
Static electricity protection measures
The working environment should be equipped with grounding devices to ensure that the static electricity of all equipment and operators can be effectively released. The operating area should maintain moderate humidity to prevent static electricity accumulation.
Ventilation facilities
The operating site must be equipped with a good ventilation system to prevent the accumulation of diffuse powder particles in the air, reduce the risk of inhalation and reduce the concentration of combustible dust in the air.
Fire prevention and fire extinguishing equipment
The operation site should be equipped with fire prevention facilities that meet the requirements, and dry powder fire extinguishers should be used for fire extinguishing first, because water or foam fire extinguishing agents may react with diffuse powder to cause a larger fire. In addition, sand or other non-combustible materials should be available for emergency covering and extinguishing of fire sources.
3. Emergency treatment and accident prevention
Emergency leakage treatment
Once the astigmatism powder leaks, all fire sources should be cut off quickly, friction should be avoided, and the powder should be swept into a sealed container with non-metallic tools to prevent diffusion. On-site personnel should evacuate immediately to prevent inhalation and contact.
Personnel protection
Operators should undergo professional training and be familiar with the properties of astigmatism powder and emergency response measures. Protective glasses, dust masks and anti-static clothing must be worn during work to reduce irritation or damage to the skin and respiratory tract.
4. Special treatment in industrial applications
Passivation treatment of magnesium powder
In order to reduce the reactivity of astigmatism powder, industrial applications often use passivation treatment on the surface of magnesium powder, such as oxide film covering or forming a protective layer with inert materials, which not only extends its storage life, but also greatly reduces safety risks.
Automated control and monitoring
Modern industrial sites can use sensors to monitor the storage environment of astigmatism powder in real time, such as temperature, humidity and static electricity level, to achieve automated alarm and control, and prevent safety accidents.
