根据带体强度及带芯结构，采用机械带扣连接，其接头的强度可达带体额定拉伸强度的60－80％。采用胶粘接头，其接头强度可达带体额定拉伸强度的90％。多种形式的接头方式可满足顾客的不同需要，保证输送系统的安全，高效运行。 　　选用重型PVG输送带代替钢丝绳芯输送带的建议： 　　随着煤炭工业的迅猛发展，井下大巷输煤所选用的胶带强度越来越高。佰特向您提出选用重型PVG输送带代替钢丝绳芯输送带的建议，重型PVG输送带与传统钢丝绳芯输送带相比具有下列特点： According to the strength of the belt and the core structure, the strength of the joints is 60-80% of the tensile strength of the belt. The adhesion joint is 90% of the tensile strength of the band. Various forms of connectors can meet the customers' different needs, ensure the safe and efficient operation of the conveyor system. Selecting heavy PVG conveyor belt to replace the advice of the steel cord conveyor belt: with the rapid development of coal industry, downhole alleys coal chooses tape strength is higher and higher. It is recommended that the heavy PVG conveyor belt be replaced with the steel cable core conveyor belt, and the heavy PVG conveyor belt will have the following characteristics compared with the traditional steel cable core conveyor belt. 1、 1. 　　带体轻，重型PVG输送带比同级钢芯带要轻得多，消耗功率也低。这一优点对较长的传输系统来说非常重要。因而它可以允许选用较小的动力驱动，并且可以长期节省能源。 Light weight, heavy PVG conveyor belt is much lighter than the same steel core and low power consumption. This advantage is important for a longer transport system. So it allows for smaller power drivers and can save energy for the long term. 2、 2, 　　重型PVG输送带具有较好的柔韧性，带体薄，输送机可选用较小直径的滚筒。 The heavy PVG conveyor belt has a good flexibility and thin body, and the conveyor can choose a smaller diameter roller. 3、 3, 　　重型PVG输送带纬向强度高，(MT668-1997标准中不限制纬向强度)，纵向抗撕裂性能高。 Heavy PVG conveyor belt is high in latitude, (the MT668-1997 standard does not limit the strength of the filling), and the longitudinal resistance to tear is high. 4、 4, 　　接头方式灵活快捷，即可采用带扣连接方式，又可采用胶接方式。接头强度高，一般可保持原带额定拉伸强度65－90％，更换、修复方便。 The connection mode is flexible and quick, can adopt belt fastener connection method, can use the glue to connect again. The strength of the connection is high, and the original band can be maintained at 65-90%, and it is easy to replace and repair.
