Superphosphate

Product characters: the white powder. Overview: calcium dihydrogen phosphate Ca (H2PO4) 2 and gypsum CaSO4 2H2O?. Also known as superphosphate. At room temperature is a gray powder, sulfuric acid decomposition apatite Ca5 (PO4) 3F obtained called ordinary superphosphate, referred to SSP, the main component of Ca (H2PO4) 2? H2O, anhydrous calcium sulfate and a small amount of phosphoric acid, containing an effective P4O10 14% ~ 20%, of which 80% to 95% soluble in water, is a water-soluble fertilizer available, directly as fertilizer, it can also be used for making compound fertilizer. Because of relatively low grade of ordinary superphosphate, sales price unit active ingredient is high, phosphate fertilizer industry and some high phosphate fertilizer. Phosphoric acid and apatite reaction, the resulting product does not contain calcium sulfate, but calcium dihydrogen phosphate, the product is called triple superphosphate, off-white powder, containing up to 30% effective P4O10 to 45% of the ordinary more than twice the SSP. Triple superphosphate is mainly used as an acidic phosphate. SSP is a mixture. Role: The triple superphosphate and sodium bicarbonate, can release carbon dioxide gas, used in food fermentation. Packaging and transportation: woven bag lined with plastic film. Moisture storage in order to avoid agglomeration leaching loss, to avoid the sun and rain, reduce nutrient loss. To pave the corrosion-resistant plate and tarpaulins on travel.
