(1)要求输送带自身质量小，抗拉强度和抗弯强度大，成槽性能好; (1) it is required that the conveyer belt have small quality, tensile strength and bending strength, which is good for the groove. 　　(2)由于承受交变弯曲载荷，故要求带芯夹层与橡胶层间要有较高的粘附强度，以防层间剥离和撕开; (2) due to the alternating bending load, it is required to have high adhesion strength between the core and the rubber layer, in case of stripping and tearing apart. 　　(3)要求加工精细，保证在受纯拉伸时，各夹层均匀承受载荷; (3) it is required to make fine processing, ensuring that the layers of the laminated layer shall bear the load evenly when it is being stretched. 　　(4)输送带的覆盖胶和夹层带芯都应具有较高的抗冲击性能和抗机械损伤性能;由于带式输送机在开机的一瞬间对输送带的拉扯力是最大的，所以，输送带必须要具有较高的抗冲击性和抗机械损伤性。 (4) the rubber and sandwich core of the conveyor belt should have high impact resistance and mechanical damage performance. Because at the moment of turning on belt conveyor conveyor belt pulling force is one of the biggest, so, conveyor belt must have high impact resistance and resistance to mechanical damage. 　　(5)为延长使用寿命，应使输送带具有足够的耐磨性;如果所使用的时间过长，就会出现磨损断裂的情况，输送带的耐磨性不够，那么使用时间很短，必须停机更换，势必会影响生产使用。 (5) to extend the service life, the conveyor belt should have sufficient wear resistance. The time is too long, if use will appear wear away the situation of fracture, the wear resistance of conveyor belt is not enough, then use a very short time, must stop change, is bound to affect the production use. 　　(6)为使驱动时所需的初张力尽量小，故要求输送带具有高摩擦系数;如果，摩擦系数过小，使用时间长以后就会出现皮带打滑等现象，影响使用。 (6) to keep the initial tension as small as possible, the conveyor belt has high friction coefficient. If the friction coefficient is too small, it will be used in the long period of time.
