The wohle core fire-retardant conveyor belt is made from the whole
belt core via dipping and plastifying in
polyvinyl chloride (PVC) dipping agent or sulfuration.
It is mainly applicable for the underground well haulage of coal
mines, and also the conveyance of
materials for metallurgical and chemical industries.
The whole core fire-retardant conveyer belt is divided into two
types: PVC, PVG.
PVC type conveyor belt's upper and lower layers are PVC coating cover, and inclined angle:
<16°with dry materials.
PVG type conveyor belt's upper and lower layers are nitrile rubber and PVC, and inclined
<20°with damp materials.
It features largely in the high strength, no delamination with
body, small elongation, large freight volume
and stable conveyance performance. Besides, it is fire retardant,
anti-static, shock resistant, wearable
and corrosion resistant.
Flame resistant property of : PVC /PVG fire-retardant conveyor belt
(1)Roller friction:The roller surface temperature is not more than
(2)Blowtorch burning(with cover) :
the average duration of flame for six samples≤3s;
the duration of flame for any individual sample ≤10s. (without
the average duration of flame for six samples≤5s;
the duration of flame for any individual sample ≤15s.
Propane burner: the length completely undamaged ≥ 250mm
Mechanical properties: It can provide users with long service life
and economic installation.
The longest service life factors: entire core was made by warp weft
filament and cover cotton woven;
dip on the special formula of pvc to make the between of core and
rubber cover to reach the high
adhesive strength ;
special formula rubber cover .
|The roller rub||≤325°C ,have no mars|
|The alcohol combustion||Average value≤3S,List value≤10S(Have no cover gum), Average
value≤5S,List value≤15S(Have no cover gum)|
|The propane combustion||Unburned reserved length >250mm|
|High energy propane combustion||Full width no damange length>2250|
