煤矿井下用MT668阻燃钢丝绳芯输送带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。 ConfigurationThe combustion-resistant steel cord conveyor belt for coal mining is using the higher strength，less elongation galvanized steel cord．which top and bottomsurface are covered with combustion—resistant ＆ anti—static rubber. The configuration is molded in invariabletensile. It can convey materials in conbustion—resistantand 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。 ApplicationThe belt has excellent performance such as fire-resistance anti-static performance，high strength，longevity，less elongation，good flexibility andth 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． 规格型号强度规格：630N／mm~4000N／mm宽度规格：800mm~2000mm SpecificationIntensity：630N／mm～4000N／mmWidth：800mm-2000mm 主要技术指标(MT668-1997)／Main Specification 1、覆盖胶性能／Cover Rubber Performance 2、钢丝绳的粘合强度／Adhesion strength of steel cord 3、安全性能(1)滚筒摩擦试验每块试样经滚筒摩擦试验时, 其任何部位不得发生有焰燃烧和无焰燃烧现象，滚筒表面温度不得大于325~C。(2)酒精喷灯试验对6块具有完整覆盖层试样，在移去喷灯后，所有试样的有焰燃烧时间的算术平均值和无焰燃烧时间的算术平均值不得大于3S, 其中每块试样的有焰燃烧时间和无焰燃烧时间单值不得大于10s。对6块剥去覆盖层试样．在移去-喷灯后，所有试样的有焰燃烧时间的算术平均值和无焰燃烧时间的算术平均值不得大于5s，其中每块试样的有焰燃烧时间和无焰燃烧时间单值不得大于15s。(3)巷道丙烷燃烧试验全宽度上保留的未损坏长度应大于250mm(4)表面电阻值试样上、下两个表面的表面电阻算术平均值不得大于3*10(8次方)欧姆产品介绍3.
