在运转过程中输送带很容易与金属部件摩擦产生火花,容易引起煤矿爆炸和着火,隐患非常大,导电性是要求不可缺少的重要部分。
In the process of operation, the conveyor belt is easy to rub with metal parts to produce sparks, which is easy to cause coal mine explosion and fire. There are great potential safety hazards. Conductivity is an indispensable part of safety requirements.
矿用托辊在条件适宜的情况下也可以采区上山运输,经过改型的带式输送机,可用于大倾角的斜井运输煤炭物料等。
Under suitable conditions, the mining idler can also be transported up the mountain in the mining area. After the modified belt conveyor, it can be used to transport coal materials in the inclined shaft with large inclination angle.
有关新标准保证使输送带有足够的导电性以把在使用中形成的静电传导出去。其输送带的电阻(resistance)值不大于3×108W,对特殊应用可规定较低值。
The relevant new standards ensure that the conveyor belt has sufficient conductivity to conduct the static electricity formed in use. The resistance value of the conveyor belt shall not be greater than 3 × 108W, lower values can be specified for special applications.
此外输送带覆盖层的电阻对温度和应力是敏感的。输送带是由多层橡胶棉帆布或者聚酯帆布上下覆有耐高温或橡胶、经高温硫化粘合在共同,适合输送175℃以下热焦碳、水泥、熔渣和热铸件等。
In addition, the resistance of the conveyor belt coating is sensitive to temperature and stress. The conveyor belt is made of multi-layer rubber cotton canvas or polyester canvas covered with high-temperature resistant or rubber and bonded together by high-temperature vulcanization. It is suitable for conveying hot coke, cement, slag and hot castings below 175 ℃.、
山东输送带厂家提醒大家,输送带的抗静电方法主要靠控制静电的产生和积累。静电的控制主要是通过减少或防止摩擦来减少静电的产生。静电的积累主要是通过地面传导,增加环境的相对湿度,并添加抗静电剂或导电材料(如导电炭黑,金属粉等)来加速静电泄漏并避免大量静电的产生。
Shandong conveyor belt manufacturer reminds you that the anti-static method of conveyor belt mainly depends on controlling the generation and accumulation of static electricity. The control of static electricity is mainly to reduce the generation of static electricity by reducing or preventing friction. The accumulation of static electricity is mainly through ground conduction, increasing the relative humidity of the environment, and adding antistatic agents or conductive materials (such as conductive carbon black, metal powder, etc.) to accelerate the leakage of static electricity and avoid the generation of a large amount of static electricity.
因此,为了赋予具有良好绝缘性能的塑料一定的导电性,以下方法:主要用于通过接枝共聚来改变聚合物结构,从而具有更多的极性基团或离子基团,并改善导电性。在输送带的实际生产过程中,在涂料配方中加入抗静电剂和导电填料,以降低输送带的表面电阻和体积电阻,使其具有一定的抗静电性能。
Therefore, in order to give plastics with good insulation properties a certain conductivity, the following methods: 1. It is mainly used to change the polymer structure through graft copolymerization, so as to have more polar groups or ionic groups and improve the conductivity. In the actual production process of conveyor belt, antistatic agent and conductive filler are added to the coating formula to reduce the surface resistance and volume resistance of conveyor belt and make it have certain antistatic performance.
