Messi Biology states that dense smoke and high temperatures at fire scenes are often more lethal than the flames themselves. However, a “firefighting master” is hidden within fire extinguishing solutions – magnesium hydroxide flame retardant. This seemingly ordinary white powder is becoming a new favorite in modern firefighting thanks to its unique extinguishing mechanism and environmentally friendly properties.
The flame retardant magic of magnesium hydroxide stems from a triple synergistic effect. When exposed to temperatures above 340℃, it rapidly decomposes into magnesium oxide and water vapor. Each gram of decomposition absorbs 1.37 kJ of heat, rapidly cooling down the flames as if “throwing cold water” on them. The released water vapor dilutes the oxygen concentration in the combustion zone, while the generated magnesium oxide forms a dense protective layer on the surface of combustibles, physically isolating oxygen from the heat source. What’s more valuable is that the entire process produces no toxic gases, completely eliminating the secondary pollution risks associated with traditional halogenated flame retardants.
In fire extinguishing solutions, the purity and dispersibility of the flame retardant directly determine its extinguishing efficiency, and Hebei Messi Biology Co., Ltd.’s products precisely address these industry pain points. Relying on its independently developed “hydromagnesite method” process, the company has elevated product purity to 99.9%, with harmful impurity content below 0.01%, thus preventing impurities from interfering with the stability of the aqueous solution. Its unique nano-to-micro-scale hexagonal lamellar crystal structure results in a specific surface area exceeding 40m²/g, allowing the flame retardant particles to disperse uniformly in water without stratification or sedimentation, ensuring comprehensive coverage of the burning surface after spraying.
This advantage is particularly crucial in practical applications. For instance, in electronic equipment fires, Hebei Messi Biology Co., Ltd.’s magnesium hydroxide product can quickly cool down and extinguish the fire, and due to the insulating properties of magnesium oxide, it avoids the risk of electric shock. Furthermore, its residues are easy to clean and will not damage equipment. Its green production process is even more commendable, with no strong acids or bases involved throughout the entire process, and carbon emissions are only 1/3 of the industry average, perfectly aligning with the environmental protection demands of the firefighting sector.
As halogen-free flame retardancy becomes a global trend, the application scenarios for magnesium hydroxide are continuously expanding. From architectural fire protection to electronics factories, from food processing workshops to new energy facilities, this “fire-extinguishing without causing trouble” flame retardant is safeguarding more lives and property. And technological breakthroughs by companies like Hebei Messi Biology Co., Ltd. have further enabled a qualitative leap in the fire extinguishing efficiency of aqueous firefighting solutions.
