Magnesium hydroxide is the ideal composite polymer material flame retardant

Plastic and other polymer materials in the combustion of the same time will produce a large number of smoke, gas, resulting in fire“Secondary pollution.”. “Secondary pollution” will bring difficulties to extinguish the fire, and cause greater harm to the people at the scene of the fire. Therefore, it is necessary to add flame retardants and other flame retardant smoke suppression or smoke suppression in polymer materials. With the development of sustainable development strategy, the addition of low-smoke halogen-free flame retardants can not only effectively improve the flame retardancy of materials, but also reduce smoke and toxic gas emissions. Among…

Recovery of cobalt by active magnesium oxide precipitation process

Recovery of cobalt from a cobalt-copper oxide ore in Congo by the process of reductive leaching-impurity removal-cobalt precipitation with active magnesium oxide was investigated. The sodium metabisulfite addition method, dosage, leaching reaction time and impurity removal reaction time were investigated, the effect of adding method, dosage and reaction time of cobalt deposition of activated magnesium oxide. The results show that when the grinding fineness is 70% , the pulp mass concentration is 33% , the pH value of control end point is 1.5-1.8 when sulfuric acid is added, and the sodium metabisulfite is added after 30 min, the pH…

Properties of Magnesium hydroxide flame retardants

Under normal temperature conditions, the synthetic magnesium hydroxide is mostly irregular sheet-shaped crystal or non-fixed crystals. The size of the grains in the <101> orientation through X-ray diffraction is lower than 7 × 10-8;Small; the particle size distribution range is wide, between 0.5-8 μm; larger than the surface area, usually at 20-100m2/g; the grains have a strong condensing into a dumplings, which is easy to reunite to form two two with a particle size of 10-100 μm.The secondary particle size and the interface of the polymerization material form a gap, which hinders the dispersion of magnesium hydroxide in the…

Flame retardant and smoke suppression mechanism of Magnesium hydroxide

Magnesium hydroxide inorganic additive flame retardants are chemical additives with the functions of smoke suppression, flame retardancy and filling, and the smoke generated is non-toxic and non-corrosive. The flame-retardant mechanism of Magnesium hydroxide When Magnesium hydroxide flame retardants are added, the polymer releases water as it decomposes and absorbs a lot of latent heat, which in turn reduces the actual temperature of the flame on the material’s surface, slow down the rate of Polymer degradation formation and reduce the production of combustible gases. Secondly, the large amount of water vapor released in the decomposition process will dilute the concentration…
