APPLICATIONS:
Application in fertilizers :
1) For PA 85.0% , its P₂O₅ ≈ 61.5%, it serves as a high-purity phosphorus source for producing water-soluble fertilizers, including NPK formulations, ensuring excellent purity and solubility.
2) Its 61.5% available P₂O₅ effectively boosts plant-available phosphorus, ideal for hydroponics, drip irrigation, and high-value crops.
3) Used as an acidifying agent to regulate pH, stabilize nutrients, and prevent Ca/Mg precipitation, improving overall fertilizer compatibility.
4) Dissolves carbonate scale in drip irrigation systems while supplying readily absorbable phosphorus.
5) High food-grade purity minimizes impurities, making it suitable for specialty fertilizers, greenhouse farming, foliar feeding, and hydroponic applications.
Application in foods :
1) Acidity regulator for cola, soft drinks, juices, improving taste and flavor.
2) Preservative effect by lowering pH to extend shelf life.
3) Nutritional fortifier as a source of phosphorus in formulas and nutrition products.
4) Processing aid in jams, candies, and bakery products to improve texture and stability.
5) CIP cleaning agent for removing scale and deposits from food-processing equipment.
Application in industry :
1)Metal treatment for rust removal, pickling, and phosphating to improve corrosion resistance.
2)Water treatment for scale inhibition and corrosion control in boiler and cooling systems.
3)Electronics and cleaning industry for semiconductor cleaning and precision descaling.
4)Other industrial uses including fertilizers, ceramics, and leather processing.
