Industrial grade monoammonium phosphate is a very good flame retardant, fire extinguishing agent, widely used in wood, paper, fabrics, fire retardant, fireproof coating agent, dry powder fire extinguishing agent, etc., but also used as high-grade water-soluble fertilizers, lithium iron phosphate precursor iron phosphate raw materials
Applications-for fire extinguishing:
The proportion of phosphorus-based fire extinguishing agents has been increasing worldwide as the global safety and fire situation has been receiving wider and wider attention. Ammonium phosphate dry powder fire extinguishing agent referred to as ABC dry powder fire extinguishing agent, in which monoammonium phosphate ( NH4H2PO4) plays a major role in extinguishing the fire, ABC class dry powder fire extinguishers said to be able to extinguish solid, liquid and gas fires.
Monoammonium phosphate for firefighting is mainly used in the production of ABC dry powder fire extinguishing agent, which mainly interrupts the chemical reaction of combustion to play a role in extinguishing fire, and is more effective than water in class B (flammable liquids) and C (electricity) fires, and is also the one with the lowest concentration, the fastest speed, and the highest efficiency among the fire extinguishing agents invented at home and abroad at the present time.
