[Chose us]

 We are soaring high among our competitors owing to the following reasons: 

1. Qualitative range
2. Rich vendor base
3. Capacious warehousing
4. Wide distribution network
5. Competitive pricing
6. Timely delivery 
 

[Properties] 


1. Its exterior shows colorless or white crystal, or white crystalloid powder or particles. It has hygroscopic property. Melting point °C 1109. Thermal decomposition young sex. Easily soluble in water (196.7 g / 100kg, 20 °C). Not soluble in alcohol. 1% aqueous pH value about 10.5.
2. In acid or alkali solution hydrolysis into potassium phosphate. Mix with water formed viscous pulpous state body. From strong aqueous person for sanshui salt. In (79 + 0.5) °C. More than 100 gesso, begin to lose °C, 180 °C and 300 °C each lose L / 3. Have other condensation of phosphate all properties. Because of aqueous alkaline strong, have the curb food corruption, defeat, fermentation role. For metallic chelated smaller (but for iron ion larger). PH buffer sex is smaller. Polymer role with other additives, weak matrix-vector effect is small.
