Certificate Analysis of Magnesium Hydroxide
1.White powder or paste
2.Soluble in diluted acid and ammonium salt and almost insoluble in water and alcohol
3. Solubility in water (18°C) is 0.9mg/100ml
4. Moh’s hardness is 2.5
5. Refractive index is 1.56
6. As temperature reaches 350°C, it begins to decompose into magnesium oxide and water
7. As temperature is above 500°C, it will change into magnesium oxide by losing water
Our product fo Magnesium Hydroxide(Fire Retardant Magnesium Hydroxide) is made from brucite mine with excellent performance on flame retardant, such as excellent smoke abatement, low hardness, decomposition temperature of 350 °C , high enthalpy and absorbtion of high heat.
Because of these chemical characters, magnesium hydroxide(Fire Retardant Magnesium Hydroxide) is widely used in PE, PP, PVC, ABS, PS, HIPS, PA, PBT, rubber industry, cable sheath in electrical appliance, cable sheath in automobiles and cable sheath in buildings and aluminium alloy composite material as flame retardant.
Certificate Analysis of Magnesium Hydroxide Flame Retardant
Solid magnesium hydroxide(Fire Retardant Magnesium Hydroxide) also has smoke suppressing and fire retarding properties. This is due to the endothermic decomposition it undergoes at 332 centigrade:
The heat absorbed by the reaction acts as a retardant by delaying ignition of the associated substance (Fire Retardant Magnesium Hydroxide). The water released diluted any combustible gases and inhibuts oxygen from aiding the combustion. Common used of magnesium as a fire retardant indude plastics, roofing and coatings. Other mineral mixtures that are used in similar fire retardant applications are natural mixtures of huntite and hydromagnesite. The use of magnesium hydroxide as a flame retardant presents the following advantages:
1. Good process ability and dispers ability, even at high filler loadings
2. Posibility of solutions aimed to specific application needs
Magnesium Hydroxide(Fire Retardant Magnesium Hydroxide) is increasing used in wast water treatment and flue gas desulfurization in USA and Japan. Seperatly, proportion is 43% and 55%.
Wast Water Treatment
Magnesium hydroxide powder(Fire Retardant Magnesium Hydroxide) is used industrially as a non-hazardous alkali to neutralise acidic wastewaters.It(Fire Retardant Magnesium Hydroxide) could remove heavy metal ion in waste water. Cu2+, Fe3+, Cr3+, Pb2+, Zn2+ could be removed totally and it is effective for Ni2+, Cd2+ when used excess magnesium hydroxide. For acid waste water, magnesium hydroxide(Fire Retardant Magnesium Hydroxide) turns Fe2+ into Fe3+ and reacts with it.
Flue Gas Desulfurization
The produced SO2 from S combustion that is found in fuel oil burned by energy plants or large steam production units, is oxidized partially to SO3 which has immediate and harmful consequenes both to the plant efficiency and the environment.
How to Use:
Spraying magnesium hydroxide powder(Fire Retardant Magnesium Hydroxide) or paste for immediate neutralization of SO3 and partially SO2. In the application magnesium is the most suitable reagent, because, besides stoichiometric advantage, as depicted on table, its(Fire Retardant Magnesium Hydroxide) main competitor CaO can not be used due to the formation of gypsum which creates hard deposits, blockage problems and other unite operational problems.
