In supplying of products, the permissible tolerance of the content of substances is established in accordance with:
TU 2182-538-00209438-2008 Diammonium Phosphate feed based on extraction phosphoric acid
TU 20.15.72-0013-48590531-2019 purified Diammonium Phosphate
Diammonium phosphate is a completely water soluble crystalline product. It is used as a raw material for the preparation of water-soluble NPP fertilizers for protected and open ground (in greenhouses, hydroponics, sprinkling systems), as a raw material for the preparation of liquid complex fertilizers. Nitrogen is necessary for the growth and development of plant biomass, takes part in photosynthesis. Phosphorus is necessary for the development of the root system of plants. DAP is used as a feed additive for animals. In addition, it is used in industry. Diammonium phosphate is an ideal flame retardant. Due to its physicochemical properties, it inhibits ignition and combustion. Due to the complete absence of insoluble impurities, the complete dissolution of diammonium phosphate is ensured and the absorption in the impregnated materials, such as fabrics, plywood or wood, is improved.
