Industrial grade sodium dihydrogen phosphate dihydrate, with a national standard content of 99%, is a raw material for water treatment buffering agents

Description :

  Sodium dihydrogen phosphate dihydrate is an important inorganic salt chemical product, mainly used as a buffering agent, water softener, and detergent raw material. In industrial applications, it can effectively adjust the pH value of solutions, maintain system stability, and is widely used in water treatment, food processing, and electroplating industries. This product meets the requirements of the national standard GB/T 15340-2008, with high purity and low impurity content. It can significantly reduce the hardness of water and prevent pipeline scaling, making it an ideal choice for industrial circulating cooling water treatment.

  The appearance of this product is white crystalline or crystalline powder, easily soluble in water and insoluble in ethanol. The main technical indicators include: sodium dihydrogen phosphate (NaH2PO4 · 2H2O) content ≥ 99.0%, chloride (Cl) ≤ 0.05%, sulfate (SO4) ≤ 0.05%, iron (Fe) ≤ 0.005%, heavy metal (Pb) ≤ 0.005%, and water-insoluble matter ≤ 0.05%. The packaging usually uses 25kg or 50kg inner plastic outer woven bags, sealed and stored in a dry and ventilated place to avoid moisture and clumping, ensuring stable product performance.

  When selecting, it is necessary to distinguish between anhydrous and dihydrate. Dihydrate has a higher molecular weight and a slightly lower proportion of active ingredients, but it dissolves faster and is suitable for rapid liquid preparation scenarios. If used for food grade applications, it is necessary to confirm whether there is a food additive production license; Industrial grade focuses on cost-effectiveness and bulk supply stability. For electronic cleaning or precision electroplating with high purity requirements, it is recommended to further detect the content of trace metal ions. If necessary, reagent grade products should be selected. For ordinary water treatment and washing aids, this industrial grade national standard product can meet the needs.

  During use, attention should be paid to protection to avoid inhaling dust or prolonged contact with the skin. Dust masks and gloves should be worn during operation. When storing, it should be kept away from acidic substances and strong oxidants to prevent mixing and reaction. When adding water treatment, it is recommended to prepare a solution first and then evenly add it to the system to better control pH fluctuations. Regularly monitoring water quality indicators and adjusting the dosage according to actual hardness changes can ensure treatment effectiveness, avoid chemical waste, and extend equipment service life.
