Flame retardant mechanism of some analysis

The purpose of the implementation of flame retardant technology , such non-flame retardant materials , flame retardant performance , under certain conditions, can not easily burn or extinguish . Non- retardant materials with flame retardant properties , the most direct way is to add flame retardants in the material . Xiaobian for you about flame retardant mechanism analysis and classification .
 1, the combustion flame to be carbonized , to organic pigments  achieve the flame-retardant effect . The flame retardant effect is mainly play a role in the solid phase , in this category are mainly phosphorus flame retardant material ( including organic and inorganic phosphorus phosphorus ) .
2 , formed under the conditions in the combustion flame is not volatile diaphragm , isolated from the air reaches retardant purposes. The flame retardant effect is mainly play a role in the liquid phase . Retardant materials in this category are mainly borates , halides , antimony oxide and phosphorus -based material , or several materials which reflect the interaction between substances generated . 3, the heat of combustion of the  magnesium stearate combustible material dispersion and dilution. Such fire-retardant material is mainly zinc borate , aluminum hydroxide , magnesium hydroxide and other substances, mainly due to the endothermic decomposition of a large , non-combustible material dilution resulting combustible gas flame to achieve the objective .
4 , flame retardants decomposition products will be cut off so as to achieve a chain reaction of hydroxyl radicals retardant purposes. The flame retardant effect is mainly play a role in the gas phase . The material in this category are mainly play a role in the gas phase . Such flame retardant and antimony oxide are mainly halide .
Flame retardant products, generally to choose non-toxic, non-polluting products, fire retardant products produced by PVC foaming board stabilizer  our company , there are halogen-free flame retardants, wood flame retardants, brominated flame retardants , in addition to sales of magnesium hydroxide , active magnesium oxide , light magnesium oxide flame retardant products .
