Combustion - Resistant Steel Cord Conveyor Belt for Coal Mining

结构
    抗拉体选用高强度、低延伸镀锌钢丝绳,上下复合配以阻燃、抗静电优质覆盖胶料,在恒张力下,通过压合成型,硫化后,使其能适应煤矿阻燃、导静电环境下物料输送。

Configuration
    The combustion-resistant steel cord conveyor belt for coal mining is using the higher strength,less elongation galvanized steel cord.which top and bottom
surface are covered with combustion—resistant & anti—static rubber. The configuration is molded in invariable
tensile. It can convey materials in conbustion—resistant
and anti—static environments after being vulcanized

用途
    适用于煤矿井下阻燃抗静电环境下使用。具有阻燃、抗静电,拉伸强度大,寿命长,使用
伸长小,成槽性好,耐曲挠性好,适用于长距离,大跨度,大运量和高速度物料输送。

Application
    The belt has excellent performance such as fire-resistance anti-static performance,high strength,longevity,less elongation,good flexibility and
th roughability. It is suitable for conveying materials at the occasion of long distance, high span,large load,and high strength in fire-resistance antistatic environments.
