What Is The Effect of Flame Retardant And Low Smoke Halogen Free Flame Retardant?

With the progress of the times, the level of identification of the causes of fire has improved. Most of the causes of fire can be identified, if there are some fire behavior with anti-detection capabilities, it takes a relatively long time, more difficult to detect, depending on the circumstances. So let's talk about another factor that causes fires, the illegal use of electrical appliances, resulting in overloaded circuits that cause fires, aging of electrical facilities and equipment, and overloading of electricity that causes fires. So what will be the performance of flame retardant wires and low smoke halogen free wires in the face of fire?

ZR-BV this wire also stands out in the wire, in the homeowner's renovation priority; not only is the price of cheap, or renovation of the construction workers are favored, but also has a durable corrosion resistance characteristics. Ordinary BV wire is suitable for electrical instrumentation equipment and power lighting fixed wiring, while ZRBV wire is suitable for electrical instrumentation equipment and power lighting fixed wiring.

Flame retardant wire and cable with flame retardant properties, extinguish, reduce or inhibit the combustion of the material, add a substance in the material or a treatment of the material, usually in the material to add a flame retardant, so that the material in the combustion of the performance of preventing or delaying the spread of flame. We take a fire engine to ignite the ZR-BV wire has obvious flame retardant effect, only a small amount of smoke generated, leaving the open flame after the wire self-extinguishing, the circumference of the insulation layer is already burned black, carbonized.

Low-smoke halogen-free flame-retardant wire is the wire insulation material halogen material, in the case of combustion, does not release halogen-containing gases, does not contain any toxic substances, produce light smoke, low concentration. Similarly, we also take a lighter to ignite the low-smoke halogen-free flame-retardant wires, will find only a trace of white smoke after burning, the insulation layer is only a small number of places to burn black, and no complete carbonization. Halogen-free, low smoke, flame retardant requirements and high safety and environmental protection requirements. Such as high-rise buildings, stations, subways, airports, hospitals, large libraries, gymnasiums, villas, family homes, hotels, hospitals, office buildings, schools, shopping malls and other crowded places.

The main feature of halogen-free and low-smoke flame retardant wires and cables is that all the materials do not contain halogens, and the amount of smoke released during combustion is very small. Halogen-containing cables in the fire release of toxicity is terrible. If the toxicity of the gas concentration that can cause death in 30 minutes is judged to be 1, then the toxicity index of PVC is 15.01, while the toxicity index of non-halogenated polymers is 0.79. In case of a fire, the strong diffusion of smoke makes the victim unable to recognize the direction, thus prolonging the period of time spent in the fire.

Whether it is flame retardant wires or low smoke halogen-free flame retardant wires, ultimately have to be defined according to the environment, price, most of the choice of low smoke halogen-free flame retardant wires it is mainly densely populated places, public places, and low smoke halogen-free flame retardant wires, long life, high temperature, in line with the European Union and Japan's environmental standards.
