In life many materials spontaneous combustion point is very low, in order to prevent them from spontaneous combustion, usually add part of the flame retardant, and magnesium hydroxide is a very good flame retardant material, then why is it said to be the best material as a flame retardant? The following Hebei Messi Biology limited company and everyone to discuss.
Magnesium hydroxide is a new type of filler flame retardant, through the heat differentiation when the release of bonded water, absorbing a lot of latent heat, to reduce the composition of the material it is filled in the flame of the external temperature, with the role of pressing the polymer differentiation and cooling of the combustible gases that occur. Let’s take a look at what advantages magnesium hydroxide as flame retardant has.
Messi Biology open lecture: what are the advantages of magnesium hydroxide flame retardant
1, magnesium hydroxide incineration dehydration generated magnesium oxide is a high-strength, high heat-resistant material, can be used as a layer of protective wall, blocking fire and toxic gases, magnesium hydroxide and acid neutralization ability is strong, can be faster and plastic incineration process of acid gas;
2, uniform particle size dispersion, good compatibility with the base material, the mechanical properties of the finished product is small;
3, magnesium hydroxide differentiation ability, high flame retardant efficiency, strong smoke suppression, low hardness, small friction on the equipment, help to extend the life of the equipment;
4, magnesium hydroxide thermal differentiation temperature of 340 ℃, 100 ℃ higher than aluminum hydroxide, conducive to the progress of plastic processing temperature, accelerate the speed of extrusion, improve the plasticizing effect, shorten the time of molding, the finished product appearance glossy, will not occur in the appearance of defects, to ensure a superb peeling strength;
5, cost-effective, magnesium hydroxide relative to aluminum hydroxide price is much lower, the filling volume is large, can significantly reduce the cost.
These are the advantages of magnesium hydroxide as a flame retardant, these advantages make magnesium hydroxide is widely used in life, through the introduction of Hebei Messi Biology Co.
