Is aluminum powder dangerous? Can aluminum powder be exported?
Aluminum powder is dangerous. The danger of aluminum powder is mainly reflected in two aspects: 1. Aluminum powder is a powder. Even flour may explode. Therefore, aluminum powder powder can easily explode if it reaches a certain content in a certain space. 2. In the nature of aluminum powder, a chemical reaction will occur when it comes into contact with water to produce hydrogen. If aluminum powder meets a large amount of water or wet, it will produce a large amount of hydrogen, which is very easy to explode. The reality tells us that the explosion of aluminum powder caused great casualties. Today we will understand whether aluminum powder is a dangerous product and the dangers of aluminum-silver powder.
Aluminum powder English name: Aluminium powder. Alias: Aluminum and silver powder CAS No.: 7429-90-5. Molecular formula: Al. Molecular weight: 26.97. Hazard mark: 10 (flammable items when wet).
Plastic bag or two-layer kraft paper bag with full or middle opening steel drum (steel plate thickness 0.5 mm, net weight per drum not exceeding 50 kg); metal drum (tank) or plastic drum outer grate box; threaded glass bottle, iron lid Ordinary wooden boxes outside of crimped glass bottles, plastic bottles or metal barrels (cans); glass bottles, plastic bottles or tin-plated steel barrels (cans) with threaded mouths, full floor lattice boxes, fiberboard boxes or plywood boxes.
It belongs to 4 categories and 1 dangerous goods. The number is 1309. But for export, although it is dangerous goods, it does not affect the export. And aluminum pellets are not dangerous goods.
Aluminum powder-containing powder coatings are the same as ordinary pigmented powder coatings. As long as they do not exceed the specified limit, there is no danger of fire or explosion. In order to ensure the safety of the entire spraying process, the separation, accumulation and concentration of aluminum powder must be avoided in the factory. These basic requirements also apply to solvent-based coatings containing copper and gold powder. However, the explosion hazard directly caused by copper-zinc alloy powder is more important than that of small aluminum powder equipment. The most important thing is that all components and operators must have good grounding. The indoor dust concentration should be controlled at the lowest level, and ventilation equipment should be used in accordance with regulations. In any case, to avoid open flames, sparks and overheated surface aluminum powder Yu is the fourth category of dangerous goods.
