The microcapsule forest fire suppressant is formulated by coating three flame retardants (phosphorus, nitrogen and silicon) with food-grade polymer materials through microcapsule processing technology. It forms core-shell structured microspheres with a diameter ranging from tens to dozens of microns, presenting as a milk-white suspension when dispersed in water. The three ingredients work synergistically to achieve a fire retardant effect of “1+1+1>3″. This product,encapsulated fire suppressant is a Class A water-based fire extinguishing agent, primarily designed for combating Class A fires.It is suitable for forest/grassland fires and other solid material fires.
The fire extinguishing mechanism is as follows:
(1)Under high temperature, the fire suppressant loses water and decomposes, producing phosphoric acid and metaphosphoric acid that cover the surface of the combustible material. This makes the material dehydrate and carbonize rapidly to form a protective film, blocking the oxidation reaction. Meanwhile, water molecules are released to cool the temperature down quickly.
(2)Silicon expands in volume at high temperature, forming a dense nano-film to coat the combustible material and interrupt the combustion process.
(3)Nitrogen produced by decomposition neutralizes the oxygen in the air. When the oxygen content drops below 16%, the flame extinguishes automatically.
Traditional forest fire retardants often suffer from poor stability, susceptibility to rain wash-off, and tendencies to oxidize, photodegrade, volatilize, or settle. These limitations render them unsuitable for establishing durable flame-retardant barriers. In contrast, this retardant utilizes a polymer encapsulation technology that significantly delays degradation. Protected by the polymer film, the retardant adheres to tree surfaces for months, maintaining a degree of flame retardancy even into the following spring when rainfall increases. This makes it particularly suitable for aerial application in constructing long-lasting firebreaks. It features eco-friendly&non-toxic, high fire extinguishing efficiency, excellent weather resistance,low-temperature resistance&easy storage and transportation.
Water-based microcapsule forest fire extinguishing agent is halogen-free, low-smoke, environmentally friendly, and non-toxic - completely eliminating the drawbacks of traditional agents. It offers highly efficient flame retardancy and enables the establishment of long-lasting firebreaks through proactive prevention, containing fires at their inception. This approach not only reduces firefighters’ exposure to raging flames and toxic smoke but also curbs fire spread, safeguarding public lives and property. Its cost-effectiveness and broad applicability provide an excellent option for global forest fire prevention.
