Flame Retardant Steel Wire Rope Core Conveyor Belt St/S 2500

Structure: Tensile body chooses high strength, low extension galvanized steel wire rope, the compound matched with flame retardant, antistatic quality cover rubber, in constant tension, through the joint forming, vulcanization, make it adapt to the coal mine flame retardant, conducting electrostatic environment material conveying
Application: Suitable for coal mine underground flame retardant antistatic, tensile strength, long service life, elongation small, good trough-forming character, good resistance to flexure interference, suitable for long distance, big span, large capacity and high speed material conveying
Safety character:
Pulley friction test: Each sample by pulley friction experiment, any positions can not happen with flame combustion and fameless combustion phenomenon, pulley surface temperature shall not be more than 617
Alcohol burner combustion: For 6 samples with complete, after taking away the burner, all sample with flame combustion time arithmetic mean value and flameless combustion time single value shall not be more than 10.0s. To 6 block stripping covering sample, after taking away the burner, all test with flame combustion time arithmetic mean value and flameless combustion time arithmetic mean value shall not be about 5.0s, of which each sample with flame combustion time and flameless combustion time single value shall not be more than 15.0s.
