Silicon phosphorus crystal from soda, phosphoric acid, calcium carbonate and other active ingredients in the 1200-1700 ºC high temperature technology made of glass beads, in the firing process to add the daily needs of the body elements of calcium, zinc, magnesium, etc. The Commonly used silicon phosphorus crystal treatment of water, the human body is a natural way to add minerals a good way. Sodium Polyphosphate Siliphos Crystal for industrial water system corrosion, scale, extend the service life of the device has played a positive role, bringing intangible economic benefits.
Main material: P2O5, Na2O, CaO
Purity of active ingredient: ≥89%
PH: 7±0.5
MF: NaO-(NaPO3)n-ONa
Other Names: Sodium polyphosphate
HS Code: 38249090
Process of Siliphos:
H3PO4+Na2CO3→NaH2PO4+Na2HPO4→(<500 °C Dehydration)STPP/SHMP→(1000°C Forming+Annealing) NaO-(NaPO3)n-ONa
Recommended dosage:
For anti-scale: 10g per 1ton water (concentration: <10ppm)
For anti-rust: 3g per 1ton water (concentration: <3ppm)
Theory of anti-scale
Ca2++Na2[Na4[PO3]6]→2Na++Na2[Na2Ca[PO3]6] (Soluble complex)
Theory of anti-rust
Fe2++Na2[Na2Ca[PO3]6]→2Na+ +Na2[Fe Ca[PO3]6] (Soluble complex)
Fe2+ +Na2[Na4[PO3]6]→2Na+ +Na2[Na2Fe[PO3]6] (Soluble complex
