Analyze the advantages and disadvantages of various flame retardants and detailed evaluation and comparison of the effect

Phosphorus flame retardant flame retardant mechanism is dehydration carbonization, so the material to have oxygen atoms, otherwise with magnesium hydroxide aluminum hydroxide to use, antimony trioxide is a flame retardant co-efficient, generally do not use alone.

According to the different methods of use of flame retardants can be divided into additive and reactive. Additive flame retardants are mainly used in combustible materials by adding flame retardants to play the role of flame retardants. Reactive flame retardants are introduced into polymer materials through chemical reactions, thereby improving the flame resistance of the material and preventing the material from igniting and inhibiting the spread of flame.

In the type of flame retardant, additive flame retardants dominate, the use of a wider range of flame retardants, accounting for about 85% of the flame retardants, reactive flame retardants accounted for only 15%.

Types

Flame-retardant science and technology is a science developed to meet the needs of social safety production and life, to prevent fires from occurring and to protect people's lives and property. Flame retardant is the application of flame retardant technology in real life, it is a special chemical additives used to improve the combustion performance of combustible and flammable materials, widely used in all kinds of decorative materials in the flame retardant processing. After the flame retardant processing of the material, when attacked by an external fire source, can effectively prevent, delay or terminate the spread of flame, so as to achieve the role of flame retardant.
