2、應(yīng)力Needle flame test針焰實驗1Flame retardantThe term Flame retardants subsumes a diverse group of chemicals which are added to manufactured materials, such as plastics and textiles, and surface finishes and coatings. Flame retardants inhibit or delay the spread of fire by suppressing the chemical reactio

3、ns in the flame or by the formation of a protective layer on the surface of a material. 1Flame retardantThey may be mixed with the base material (additive flame retardants) or chemically bonded to it (reactive flame retardants). Mineral flame retardants are typically additive while organ halogen and

4、 organophosphorus compounds can be either reactive or additive.2Fire safety standardsFlame retardants are typically added to industrial and consumer products to meet flammability standards for furniture, textiles, electronics, and building products like insulation.2Fire safety standardsIn response t

5、o concerns about the health impacts of flame retardants in upholstered furniture, in February 2013 California proposed modifying TB 117 to require that fabric covering upholstered furniture meet a smolder test and to eliminate the foam flammability standards . Gov. Jerry Brown signed the modified TB

6、117-2013 in November and it became effective in 2014. The modified regulation does not mandate a reduction in flame retardants.3Test methods The plastic material is in the test, two of heat resistance test are hot wire test and needle flame test, the two test methods of test points are different.1、Glow wire test It is used to simulate heat source technology assessment in the environment such as hot components or overload resistance, fire hazard caused in a short period of time of thermal stress, it is for the origin of the simulated heat source after hot wire electric heating 2、Nee
