Applications
Potassium dihydrogen phosphate has applications across a wide range of sectors, including pharmaceutical support, industrial processing, and agricultural cultivation, with its functions focused on the core needs of each scenario.
● Pharmaceutical Excipients: Regulates the pH of tablets, capsules, and injections to ensure drug stability and effectiveness.
● Nutritional Supplements: Balances electrolytes and maintains acid-base stability. Suitable for people with hypokalemia, it can also supplement phosphorus and potassium for the elderly and those who exercise.
● Disease Treatment: Improves electrolyte or acid-base imbalances caused by kidney and cardiovascular diseases, helping to restore bodily functions.
● Electronics Industry Materials: Used as a semiconductor cleaning agent and battery electrolyte additive, it meets the needs of high-end electronics manufacturing.
● Experimental Buffers: Maintains pH stability in chemical and biological experimental systems, ensuring experimental or production accuracy.
● Food Additives: Regulates food acidity, enhances nutrition, and aids the fermentation process in alcohol and MSG production.
● Water Treatment Agents: Softens water, inhibits scale formation, and provides phosphorus nutrients to wastewater microorganisms, assisting in the treatment of wastewater containing heavy metals.
● Crop Nutrient Supplementation: Provides phosphorus and potassium nutrients to food and cash crops, promoting photosynthesis, increasing yields, and improving fruit quality.
● Crop Stress Resistance Enhancement: Enhances crop resistance to drought, cold, and disease, mitigating the impact of extreme environments on crops.
● Crop Fertilization Methods: Supports foliar spraying and drip irrigation, with foliar spraying being widely used due to its high nutrient utilization rate and rapid results.
In addition, it can be used to adjust the pH of dye baths in printing and dyeing, and as a flux in ceramic glazes. However, these applications are smaller in scale and not a core focus.
