Wuhan South Light Technology Development Co., ammonium dihydrogen phosphate [Formula] NH4H2PO4 [Molecular weight] 115.0 CAS 7722-76-1 [Executive standard] GB10205-2009 [nature] of ammonium dihydrogen phosphate as white crystals, soluble in water. Stable in the air, when a small amount of decomposition at 100 ℃. The relative density of solids is 1.803 (19 ℃), melting point of 190 ℃. Partial loss of ammonia and water to form a mixture of ammonium phosphate and phosphoric acid is higher than the melting point. Aqueous acidic reaction, 1% aqueous solution PH value of 4.5. [Use] dihydrogen phosphate ammonium phosphate products are mainly used for wood, paper, fabric for fire retardant, also used as a fire retardant paint additive powder extinguishing agent. In the food industry as a leavening agent, nutritional agent. On agriculture as a non-chloride N, P binary efficient fertilizer use, the total nutrients (N + P2O5) was 73%, which is the preparation of N, P, K compound fertilizer-based raw materials. Is a water-soluble fertilizer available, the total effective nutrient content of more than 72%, phosphorus (P2O5) and the proportion of total nitrogen (N) content of about 5.12: 1, is one of the main varieties of high concentrations of phosphate and compound fertilizer. The product is generally used for fertilizer, but also the production of compound fertilizer, BB fertilizer on the basis of the most important raw materials; The product is widely used in rice, wheat, corn, sorghum, cotton, fruits, vegetables and other food crops and cash crops; widely used in all kinds of soil red soil, brown, yellow soil, black, cinnamon, purple soil, soil and other white pulp; especially suitable for the northwest, north and northeast regions of drought administration. [Packing] plastic woven bag, net weight 25KG, stored in ventilated and dry place.
