山東瀚邦膠帶有限公司的煤礦井下用MT668阻燃鋼絲繩芯輸送帶
Combustion - Resistant Steel Cord Conveyor Belt for Coal Mining

結(jié)構(gòu)
    抗拉體選用高強(qiáng)度、低延伸鍍鋅鋼絲繩，上下復(fù)合配以阻燃、抗靜電優(yōu)質(zhì)覆蓋膠料，在恒張力下，通過壓合成型，硫化后，使其能適應(yīng)煤礦阻燃、導(dǎo)靜電環(huán)境下物料輸送。

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
    適用于煤礦井下阻燃抗靜電環(huán)境下使用。具有阻燃、抗靜電，拉伸強(qiáng)度大，壽命長，使用
伸長小，成槽性好，耐曲撓性好，適用于長距離，大跨度，大運(yùn)量和高速度物料輸送。

Application
    The belt has excellent perbance such as fire-resistance anti-static perbance，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．
