The trolley-type dry powder fire extinguisher is also called ammonium phosphate fire extinguisher, commonly known as ABC dry powder fire extinguisher. It adopts the latest fully siliconized moisture-proof technology, which has the characteristics of good fluidity, long storage period, not easy to be damp and agglomerated, and good insulation. It is mainly used for Fighting solid material fires (Class A), flammable liquid fires (Class B), flammable gas fires (Class C) and general electrical fires, it is necessary for aircraft, ships, vehicles, warehouses, factories, schools, shops, oil depots and other places of fire fighting equipment.
The ABC dry powder fire extinguisher relies on the volatile decomposition of inorganic salts in the dry powder to chemically inhibit and negatively catalyze the free radicals or active groups produced by the fuel during the combustion process, so that the chain reaction of combustion is interrupted and the fire is extinguished; the second is The dry powder falls on the surface of combustibles, a chemical reaction occurs, and a glass-like covering layer is formed under the action of high temperature, thereby isolating oxygen and suffocating the fire.
The portable dry powder fire extinguisher produced by our company has specifications25kg,35kg,50kg.The cylinder body is made of carbon steel, not afraid of pressure, not afraid of extrusion, the color of the body is bright, rust-proof, pressure-resistant and corrosion-resistant.
