Diammonium hydrogen phosphate is an inorganic compound, colorless and transparent monoclinic crystal or white powder. In order to increase storage stability, some products add a coating agent during the production process to make the product appear brown. It is a compound fertilizer containing two nutrients: nitrogen and phosphorus. It is easily soluble in water and insoluble in ethanol. It has certain hygroscopicity and is easy to decompose in humid air, volatilizing ammonia and turning into ammonium dihydrogen phosphate. The aqueous solution is weakly alkaline potassium dihydrogen phosphate, pH 8.0. Decomposes when heated to 155°C. Melts at 190℃ and decomposes to release ammonia and water.
Instructions for use
1. This product does not contain chloride ions, has good stability, and is widely used in various soils and crops (such as cotton, rice, wheat, corn, fruits, vegetables, medicinal materials, etc.).
2. It can promote plant photosynthesis, make crops grow vigorously, seedlings are strong, and flowers are preserved.
3. Enhance disease resistance, cold resistance, wind-heat resistance, lodging resistance, promote early maturity, and increase production and income.
Purpose
1. Industrial grade is used to impregnate wood and fabrics to increase their durability;
2. Fertilizer grade is mainly used as a high-concentration nitrogen-phosphorus compound fertilizer. It is a high-efficiency fertilizer widely applicable to vegetables, fruits, rice and wheat; it is especially suitable for crops that love nitrogen and require phosphorus, and can be used as base fertilizer or top dressing. , should be applied deeply. It has good miscibility with urea, ammonium nitrate and ammonium chloride. Since it does not contain potassium, it should be applied together with potassium fertilizer (potassium chloride, potassium sulfate).
3. Used as feed additive for ruminants;
4. Used as analytical reagents, buffers, and water softeners;
Anti-fog agent
5. Can be used as dry powder fire extinguishing agent and phosphorus for fluorescent lamps;
6. Used for printing plate making, manufacturing of electronic tubes, ceramics, enamel, etc., and biochemical treatment of wastewater;
7. The military industry uses it as a flame retardant for rocket engine motor insulation materials.
8. Used as a curing agent for urea-formaldehyde resin adhesive, it is formulated into a 20% aqueous solution with the slowest curing speed. Also used as additive flame retardant. If a small amount of DAP is added to the natural rubber emulsion, the magnesium ions in the latex can be effectively eliminated without reducing the tensile strength of the natural rubber latex after vulcanization.
Storage and transportation
Should be stored in a cool, ventilated and dry warehouse. The packaging should be sealed and moisture-proof. Protect from rain and sun during transportation. Be careful when loading and unloading to prevent damage to the packaging.
