PVC PVG fire-retardant conveyor belt

The whole core fire-retardant conveyor belt is made from the whole belt core via dipping and plastify 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.

Introduction

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.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 angle: ＜20°with damp materials.

Tensile strength (N/mm)

Grade	Fourth	Fifth	Sixth	Seventh	Eighth	Ninth	Tenth
Types	680s	800s	1000s	1250s	1400s	1600s	1800s

Flame resistant property

(1)Roller friction：The roller surface temperature is not more than 325℃

(2)Blowtorch burning(with cover) ：

the average duration of flame for six samples≤3s;

the duration of flame for any individual sample ≤10s. (without cover):

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

Surface electricity resistance value

The average electrical resistance of both surfaces ≤3.0×108Ω

Safely performance

It has been passed the flame retardant test and static test and got the safety Certificate of approval for mining products.

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 .
