Use of monoammonium phosphate

Monoammonium phosphate is white powdery or granular (granular products have higher particle compressive strength), density 1.803 (19℃). Melting point is 190 ℃, soluble in water, slightly soluble in alcohol, insoluble in acetone, 100 g water solubility under 25 ℃ is 41.6 g, heat generated 121.42 kJ/mol, 1% aqueous solution pH value of 4.5, a neutral and stable under normal temperature, no oxidation reducing, in high temperature, acid and alkali, oxidation of reducing substances not combustion, explosion and has good solubility in water, acid, powder product has certain moisture absorption, at the same time has good thermal stability, and at high temperatures may get dehydrated into thick focal ammonium phosphate, ammonium polyphosphate, partial chain compounds such as ammonium phosphate. Sprinkles and disposal methods: Simple cleaning can be. Transportation and storage protection measures: To prevent the product from agglomerating and deteriorating due to moisture, it should be stored in the room or covered with cloth and other protective materials, and at the same time to avoid the product exposed to the sun.
Product Classification:

1. According to the manufacturing process, it can be divided into wet production of monoammonium phosphate and thermal production of monoammonium phosphate;

2. According to the composition content, it can be monoammonium phosphate for agricultural use, monoammonium phosphate for general use, 98% (grade 98) of industrial/food monoammonium phosphate, 99% (grade 99) of industrial/food monoammonium phosphate, and it can also be divided into one class, two classes and three classes.

3, according to the use can be divided into agricultural grade ammonium phosphate, industrial grade ammonium phosphate, food grade ammonium phosphate; In the application of agriculture, industry and food, it can also be classified into compound fertilizer, fire extinguishing agent, leavening agent, monammonium phosphate and so on.

Application: Monoammonium phosphate (MAP) for agricultural use is a water-soluble and quick-acting compound fertilizer. The ratio of available phosphorus (AP2O5) to total nitrogen (TN) content is about 5.44:1. It is one of the main varieties of high-concentration phosphate compound fertilizer. The product is generally for topdressing, is also the production of ternary compound fertilizer, BB fertilizer the most basic raw materials; The product is widely used in rice, wheat, corn, sorghum, cotton, melon and fruit, vegetables and other food crops and cash crops; Widely used in red soil, yellow soil, brown soil, yellow tide soil, black soil, brown soil, purple soil, white slurry soil and other soil; Especially suitable for northwest China, North China, northeast China and other dry areas with little rain.

Industrial monoammonium phosphate (MAP) is a kind of very good flame retardant, fire extinguishing agent, flame retardant is widely used for wood, paper, fabric, fiber processing and dye industry of dispersant, enamel glaze agent, chelating agent, dry powder fire retardant coating, moreover can also be used as a feed additives, pharmaceuticals and printing industry has used, also used as a high-grade fertilizer.
