Product introduction: monoammonium phosphate
Ammonium dihydrogen phosphate, a chemical agent, also known as monoammonium phosphate, is a white crystal with molecular formula of NH4H2PO4. It will decompose into ammonium metaphosphate (nh4po3) when heated. It can be made by the reaction of ammonia and phosphoric acid. It is mainly used as a fire retardant for fertilizer, wood, paper and fabric, as well as pharmaceutical and ruminant feed additives.
Properties: white crystalline powder. Stable in air. 1g dissolved in 2.5ml water. Slightly soluble in ethanol, insoluble in acetone. The aqueous solution is acidic. The solubility in water at room temperature (20 ℃) is 37.4g. Relative density 1.80. Melting point 190 ℃. The refractive index is 1.525.
Product purpose:
This product is mainly used as fertilizer, fireproof agent for wood, paper and fabric (such as the extinguishing agent for matchstick and candle wick), and also for making drugs. It is also used as feed additive for ruminants.
As a fertilizer, it is suitable to apply ammonium phosphate during crop growth. Ammonium phosphate is acidic in soil and may have adverse effects if it is too crystallized with seeds. It is better than ordinary calcium and ammonium sulfate in acidic soil and better than other fertilizers in alkaline soil; Do not mix with alkaline fertilizer to avoid reducing fertilizer efficiency. If lime is to be used in acid soil in the south, monoammonium phosphate should be applied after a few days.
Product packaging and storage:
This product is sealed and packed with plastic bags inside and woven bags outside. Each bag has a net weight of 25kg and tons. The product should be stored in a ventilated and dry warehouse, away from heat source, fire source and water source, and avoid rain and direct sunlight.
