Specific applications of ammonium dihydrogen phosphate

Ammonium dihydrogen phosphate is a white crystalline substance that is soluble in water and contains two essential nutrients: nitrogen and phosphorus. It is relatively stable in nature and has practical applications in various fields such as agriculture and industry.
In agricultural cultivation, it is a commonly used fertilizer. Since it contains both nitrogen and phosphorus, it can meet the nutritional needs of crops at different growth stages. For example, when growing field crops like corn and wheat, applying some Ammonium Dihydrogen Phosphate during the seedling stage and the jointing stage can promote root growth and make the stems stronger. When growing vegetables like tomatoes and cucumbers, during the fruiting stage, there is a high demand for phosphorus. Using it as a top-dressing fertilizer can increase fruit yield and ensure more uniform ripening. It can also be used for indoor plants. Dilute it and water the flower pots with it to make the leaves greener and the flowers more vibrant. However, be careful about the concentration when using it, and avoid applying it directly to the roots to prevent root burn.
In industry, ammonium dihydrogen phosphate is commonly used as a flame retardant. At high temperatures, it decomposes into ammonia gas and water vapor, which isolate oxygen and extinguish fires. Adding small amounts of ammonium dihydrogen phosphate during the processing of plastics and wood products can improve their fire resistance. In building materials, such as fire-resistant coatings, it is also used. When applied to steel structures, it can slow down the rate of temperature increase in steel during a fire, buying more time for rescue efforts.
In the food industry, Ammonium Dihydrogen Phosphate can be used as a food additive. It can regulate the acidity and alkalinity of food, making the texture of some processed foods more stable. For example, when baking bread or cakes, adding a small amount can help the dough ferment more evenly, resulting in a lighter and fluffier texture in the final product. In some beverages, it can also act as a buffer, helping to maintain consistent acidity and sweetness, preventing the beverage from spoiling due to changes in storage conditions. However, there are strict dosage standards for its use in food, which must comply with national regulations to ensure safety.
Additionally, in the pharmaceutical field, Ammonium Dihydrogen Phosphate has certain applications. It can serve as an excipient in drug formulations to help regulate the pH value of the solution, making the medication more stable. In some oral solutions, it can also assist in regulating osmotic pressure, making the solution more suitable for human absorption.
When using Ammonium Dihydrogen Phosphate, it is important to note that it has a certain degree of hygroscopicity. It should be stored in a dry, well-ventilated area and sealed properly to prevent moisture absorption and caking. If used as a fertilizer, it is best not to mix it with alkaline fertilizers, as this may reduce its efficacy. Industrial-grade and food-grade Ammonium Dihydrogen Phosphate have different standards and should not be mixed. Food-grade Ammonium Dihydrogen Phosphate has a higher purity and fewer impurities.
In summary, ammonium dihydrogen phosphate is a versatile chemical that plays a significant role in various fields by regulating, supplying nutrients, and acting as a flame retardant, thereby bringing considerable convenience to production and daily life. It is a highly practical substance.
