What Cause The Burning Explosion of Powder Coating

The following aspects are the factors that lead to the burning explosion of powder coating (1) The dust concentration exceeds the lower limit Due to these reasons, the dust concentration in the powder room or workshop exceeds the lower explosion limit, thus forming the main conditions for powder burning explosion. If the ignition source is moderate, burning explosion are likely to occur (B) Powder and paint shop mixing In some factories, due to the small area of ​​the workshop, in order to save the workshop, the powder coating and paint workshops are mixed in one workshop. Two sets of equipment are placed side by side or in series in a line, sometimes using solvent-based paint, sometimes using a powder spraying system, which causes the paint to fill the entire workshop with volatile flammable gas, and the dust leaking from the powder spraying system floats in the workshop, forming a powder-gas mixed environment, which has a relatively high performance. Great risk of fire and explosion (C) Ignition source The ignition source caused by powder combustion mainly includes the following situations: Fire, An ignition source that causes powder to burn and is one of the most dangerous open flames. If the powder site is in a dangerous area, there are welding, oxygen cutting, lighter ignition, match cigarette lighters, candles, etc., which may cause fire and explosion. Heat source, In the gunpowder danger zone, a piece of red-burning steel, the non-explosion-proof light suddenly breaks, the resistance wire is suddenly cut off, the infrared board is energized and other combustion sources may cause the gunpowder to burn. The electrostatic discharge in the powder room is limited. When the dust concentration of the sandblasting and powder spraying guns comes into contact with the workpiece or the powder room suddenly with electrostatic sparks, or when the motors and electrical appliances are ignited, the powder will burn.
