Problems solved by technology

The newly used halogen-free flame retardants have less smoke, little or no toxicity, but contain a lot of hydrated substances. When the temperature is high, the dehydration reaction reduces the physical and mechanical properties of the cable, so the flame retardant temperature cannot be high.
[0004] In short, due to the use of a single flame retardant material, the cable either produces a lot of smoke and toxic gases or reduces the performance of the cable due to dehydration reaction, thus affecting the flame retardant temperature and flame retardant time of the cable
As we all know, due to the heavy rain in southern my country, the cable trenches or cable tunnels are relatively easy to be washed and damp by rainwater, and the traditional fireproof sealing materials used in traditional cable trenches, such as inorganic blockage materials or fire retardant bags, are washed by rainwater. , easy to be deformed by moisture, poor in stability, and the effective performance of fire resistance is seriously affected, and it is difficult to achieve the effects of flame retardancy, fire prevention and moisture resistance
