Product UsageWater soluble fertilizer:
It is mainly used as high-concentration nitrogen and phosphorus compound fertilizer, which is a kind of high-efficiency fertilizer
widely applicable to vegetables, fruits, rice and wheat.It is especially suitable for nitrogen - loving and phosphorous crops. It can be used as base fertilizer or top fertilizer.With urea, ammonium chloride can be mixed, because it does not contain potassium, should be applied with potash (potassium chloride, potassium sulfate).
Industrial use
1.It can be used as a dry powder extinguishing agent, phosphor for fluorescent lamps;
2. Used for printing plate making, vacuum tube, ceramic, enamel and other manufacturing, wastewater biochemical treatment;
3. Used as curing agent of urea-formaldehyde resin adhesive, with 20% aqueous solution, the slowest curing speed.It is also used as additive flame retardant.If a small amount of DAP is added to the natural rubber latex, magnesium ions in the latex can be effectively eliminated without reducing the tensile strength of the natural latex after vulcanization.
Food additives
In the food industry as starter, nutrition agent, etc.
Product PackingPacking:25kg/50kg bag or as customer's request Storage: Store in a cool, dry area and not in direct sunlight. The preferred storage temperature should not exceed 0ºC-30ºC.Shelf Life: 24 Months.
