Storage conditions
1. It should be stored in a cool, ventilated, dry, and clean warehouse, protected from moisture, high temperature, and pollution from toxic and hazardous substances. It should not be stored and transported together with toxic and hazardous substances.

2. Protect from rain and scorching sun during transportation. Be careful when loading and unloading, so as not to break the package.

3. In case of fire, water, sand and various fire extinguishers can be used to put out the fire.

Stability
1. Avoid contact with oxides and air; the air is relatively stable, a small part of it will decompose at 100℃, and it will gradually decompose and lose ammonia and water when heated to above 130℃, forming a mixture of ammonium metaphosphate and phosphoric acid. When exposed to the air, it gradually loses ammonia and becomes ammonium dihydrogen phosphate.

2. The aqueous solution is alkaline, and the pH value of 1% solution is 8. Reacts with ammonia to generate triammonium phosphate. It gradually loses about 8% NH3 when exposed to the air.

Function
1. Prepare buffer and medium. Corrosion inhibitor. Fire retardant for textiles, paper, wood, vegetables, fiber. Flux for soldering tin, copper, zinc, etc. Refined sugar. Chemical fertilizers. Bread improver. Food additives. In the field of water treatment, it is mainly used as a corrosion inhibitor and bacterial nutrient in the biochemical treatment of wastewater, and it is also used as a water softener component of boiler water. It can also be used as a dry powder fire extinguishing agent, welding flux, yeast cultivation nourishment, leavening agent for manufacturing fermented food and bread. It has a flame retardant effect in fabrics, paper, wood and plant fibers. In addition, it is also used in fertilizers, feed additives, printing plates, pharmaceuticals, electronic tube manufacturing, ceramics and enamel industries and other fields. Analytical reagents for precipitation of magnesium, zinc, nickel, uranium, etc.

2. Used as a food leavening agent, dough regulator, buffer, and yeast food

3. Used as a feed additive for ruminants.

4. In the food industry, it is used as a food leavening agent, dough regulator, yeast food and fermentation aid for brewing. Can be used as a buffer.

5. Used as analytical reagent, such as pH buffer, magnesium, zinc, nickel and other precipitants, supporting electrolyte in electrochemical analysis, also used as seed soaking agent, corrosion inhibitor, preparation medium reagent.

6. Used for flame-retardant treatment of fabrics, paper, wood and plant fibers; impregnation treatment of the wick to increase its durability; self-extinguishing treatment after the match is ignited. It can be used as a dry powder fire extinguishing agent and phosphorous in fluorescent lamps, soldering flux of tin, copper, bronze and zinc, a culture nutrient for yeast, and a leavening agent for the manufacture of fermented food and bread. Used in sugar refining (purification) process. Used for chrome dyeing of wool fabrics in the printing and dyeing industry. Used as fertilizer and feed additive in agriculture. In addition, it is also used in the printing and platemaking industry, the pharmaceutical industry, the electronic tube manufacturing industry, and the ceramic and enamel industry.
