use: widely used as phosphor and autunite additive for aquatic,the phosphor resource absorbed by aquatic.The phosphor resource must be provided by water dissolved form.According to the test,the aquatic's utilization of phosphor is perfect.The best one is autunite phosphate,water-solubility phosphor is 90%,effective utilization of phosphor is 98%,higher 20%--60% than calcium phosphate.The character,cost and integrate factor is much higher the other phosphor resources.
Character: the proportion of phosphor and autunite is nearly to theory value 1.50,more balance,more perfect in sanitation,the guideline of fluorin ,lead and arsenic is better than industry standard.Not contain dissociate acid,not agglomeration,perfect fluxion and scatter character,contain no black point,whiteness appearance.
Packing: 50kg net plastic woven bags,saved in airness and dry place
