6.Usage:
Diammonium phosphate (DAP), also called diammonium hydrogen phosphate or ammonium phosphate dibasic is a white crystalline compound widely used as a high-concentration nitrogen and phosphorus compound fertilizer suitable for various crops (e.g., vegetables, fruits, rice, wheat) and soil types, especially in arid regions . In addition to agriculture, it serves as a flame retardant for wood, paper, textiles, and other materials, as well as an ingredient in dry powder fire extinguishers and fluorescent lamp phosphors . DAP is also used in printing plate making, electronic tube manufacturing, ceramics, enamel production, and as a feed additive for ruminants .Furthermore, DAP is employed in water treatment (as a corrosion inhibitor or bacterial nutrient in wastewater biochemical treatment) and in laboratories as a buffer, analytical reagent, or support electrolyte
In food industry, it is used as food leavening agent, dough regulator. Yeast food, brewing fermentation agent and buffering agent.
