ISO9001 Approved Water Based Flame Retardant

Ammonium Polyphosphate Water Based Fire Retardant With Low Arsenic

Advantages

Good stability. Water-based flame retardant has the characteristics of good stability, not easy to decompose, not easy to volatilize, and lasting effect.

Good security. The water-based flame retardant not only can obtain a high flame retardant effect, but also has a small amount of smoke generation and low toxicity. The amount of toxic gas and smoke generated during fire is low.

Application

Can be made into 20% P-N flame retardant liquid. It can be widely used in water-soluble flame retardant coatings, and high-concentration binary compound fertilizers, slow-release fertilizers, ion exchangers and dispersants in the mining industry.

Used for fire-resistant treatment of textiles, paper products, fibers, wood, etc. After special treatment, high concentration (50%) flame retardant liquid can also be made to meet special needs.

Water-soluble ammonium polyphosphate is also called ammonium polyphosphate or ammonium polyphosphate , referred to as APP, and its molecular formula is (NH4)(n+2)PnO(3n+1) , in which the content of nitrogen and phosphorus is relatively high . According to the degree of polymerization , it can be divided into low polymerization , medium polymerization and high polymerization . The lower the degree of polymerization , the higher the water solubility . Conversely, the lower the water solubility, when n>20, it is an APP with poor water solubility, and when n<20 , it is an APP with high water solubility . Due to its different water solubility, ammonium polyphosphate is also widely used . Water-soluble ammonium polyphosphate, because of its relatively low melting point and sintering point , can be quickly melted at a lower temperature , penetrates into the pores of combustibles , isolates combustibles from the air , and further polymerizes and decomposes to form a film , Quickly cover all levels of combustibles to extinguish the flame , so as to achieve the purpose of extinguishing the fire . Therefore , it can be used to make dry powder fire extinguishing agent , which is used to extinguish paper , fabric , wood and other materials . In addition , because of its stable chemical properties , the pH is close to neutral , and its solubility is good ; and it contains high nitrogen and phosphorus elements required by plants , and has strong chelation of metal ions . It can also be used to make liquid compound fertilizers , and by gradually Hydrolyzed , well absorbed by plants , can be used as a slow-dissolving long-acting fertilizer .

Foreign research on water-soluble ammonium polyphosphate started relatively early in the early 1970s . The TVA company in the United States ammoxidized wet-process phosphoric acid with a P2O5 mass fraction of 54% in a tubular reactor . The product contains the melt of water-soluble Ammonium Polyphosphate. In the late 1970s , countries such as Japan and the former Soviet Union began mass production of water-soluble ammonium polyphosphate and applied it to agriculture. In the late 1980s, RCE India set out to develop a granulated water-soluble ammonium polyphosphate fertilizer process. In China, the research on this aspect is relatively late. In the 1980s, research on the synthesis process and application of water-soluble ammonium polyphosphate began. There are few manufacturers selling water-soluble ammonium polyphosphate on the market, the price is relatively expensive and the product performance is not very stable. The purification and purification of water-soluble ammonium polyphosphate needs further study .
