Product description of Industrial-grade sodium hexametaphosphate
Product Description of Industrial-grade Sodium Hexametaphosphate (SHMP)
Chemical formula: (NaPO₃)₆
CAS Number: 10124-56-8
Appearance: White powder or colorless transparent glassy granules
Solubility: Readily soluble in water, and the aqueous solution is weakly alkaline
I. Product Features
Strong chelating ability
It can form stable complexes with metal ions such as Ca²⁺ and Mg²⁺, effectively softening hard water.
The dispersion effect is prominent
It prevents particle aggregation and is widely used for suspension stabilization.
pH buffering performance:
Maintain the pH of the system at 5.5-7.5, which is suitable for a variety of industrial scenarios.
High-temperature resistance
It still maintains chemical stability in high-temperature environments (≤200℃).
Ii. Technical Parameters (Typical Industrial-grade Standards
Total phosphate (calculated as P₂O₅) ≥68.0% GB/T 18962-2003
Water-insoluble matter ≤0.05% by gravimetric method
pH value (1% solution) 5.8-7.3 pH meter method
Heavy metals (calculated as Pb) ≤10ppm ICP-MS
Iii. Main Application Fields
Water treatment industry
Function:
Boiler water corrosion and scale inhibitor, circulating cooling water system dispersant.
Advantages:
It is more heat-resistant than sodium tripolyphosphate (STPP) and suitable for water with high hardness.
2. Detergents and cleaners
Function:
Enhance the decontamination power and prevent the redeposition of dirt (note the phosphorus content limit in some areas).
3. Oil extraction
Purpose:
Drilling mud additive, controls clay expansion and improves the stability of drilling fluid.
4. Ceramics and Building Materials
Application:
Ceramic slurry de-gumming agent, reducing viscosity; Cement retarder.
5. Other industrial uses
Textile printing and dyeing (anti-dyeing agent), papermaking (bleaching stabilizer), metal surface treatment (rust removal auxiliary).
Iv. Packaging and Storage and Transportation
Packaging:
25kg per bag (lined with PE film kraft paper bag), 500kg per ton bag, customizable.
Storage
Keep in a cool and dry place, protected from moisture and isolated from acids.
Transportation:
Non-hazardous materials, transported by regular logistics.
V. Highlights of Market Competitiveness
High-purity process
The thermal phosphoric acid process is adopted, with low impurity content, making it suitable for high-end industrial demands.
