Function：
1. Ammonium polyphosphate will decompose and produce phosphoric acid and metaphosphoric acid when heated, which can promote the dehydration and carbonization of the material, and form a layer of carbon foam on the surface of the material, which can play the role of flame retardant.
2. Ammonium polyphosphate is a compound fertilizer containing nitrogen and phosphorus. The ammonium nitrogen can be directly absorbed and utilized by plants, while the phosphorus element can be gradually hydrolyzed in the soil.
3. Ammonium polyphosphate can form soluble complexes with calcium, magnesium and other metal ions in water, thus preventing these metal ions from forming scale in water.
Application:
1. In polyolefin plastics (such as polyethylene, polypropylene), ammonium polyphosphate can be used as an efficient flame retardant.
2. For some natural fibers (such as cotton, hemp) and synthetic fibers (such as polyester) fabrics, ammonium polyphosphate can be added by impregnation, coating and other ways in the production of some fire curtains, fireproof work clothes and other textiles.
3. Wood is a flammable material, ammonium polyphosphate can be applied to wood flame retardant treatment by impregnation or surface coating.
4. In agriculture, it can be used as base fertilizer or trailing fertilizer. And it is also widely used in drip irrigation, sprinkler irrigation and other irrigation and fertilization systems due to its good solubility properties.
5. In industrial circulating cooling water system, ammonium polyphosphate can be used as corrosion and scale inhibitor. It plays an important role in the circulating cooling water system of chemical industry, iron and steel industry.
