Abstract

Textile-reinforced conveyor belts are most widely used in various industries, including in the mining, construction, and manufacturing industries, to transport materials from one place to another. The conveyor belt's tensile strength, which primarily relies on the property of the carcass, determines the area of application of the belt. The main aim of the current work was to investigate the influence of vulcanization temperature and duration of the vulcanization process on the tensile properties of the carcass part of the conveyor belt. An extensive experiment was carried out on the tensile properties of woven fabrics that were intended to reinforce conveyor belts by aging the fabrics at the temperature of 140 °C, 160 °C, and 220 °C for six and thirty-five minutes of aging durations. Afterward, the textile-reinforced conveyor belts were produced at vulcanization temperatures of 140 °C, 160 °C, and 220 °C for six and thirty-five minutes of vulcanizing durations. The influence of the vulcanization process parameters on the tensile property of fabrics utilized for the reinforcement of the conveyor belt was analyzed. In addition, the effect of the dipping process of woven fabric in resorcinol-formaldehyde-latex on the tensile property of polyester/polyamide 66 woven fabric (EP fabric) was investigated. The investigation results revealed that the tensile strength of the carcass of the conveyor belt was significantly affected by vulcanization temperature. The conveyor belt vulcanized at 160 °C for 35 min has shown the optimum tensile strength, which is 2.22% and 89.06% higher than the samples vulcanized at 140 °C and 220 °C for 35 min, respectively. Furthermore, the tensile strength and percentage elongation at break of conveyor belts vulcanized at 220 °C were almost destroyed regardless of the vulcanization duration.

摘要

纺织增强输送带在包括采矿、建筑和制造业在内的各种行业中应用最为广泛，用于将物料从一个地方运输到另一个地方。输送带的拉伸强度主要取决于骨架的性能，它决定了输送带的应用领域。当前工作的主要目的是研究硫化温度和硫化过程持续时间对输送带骨架部分拉伸性能的影响。对旨在增强输送带的机织物的拉伸性能进行了广泛实验，通过在140℃、160℃和220℃的温度下对织物进行6分钟和35分钟的老化处理。之后，在140℃、160℃和220℃的硫化温度下，硫化持续时间为6分钟和35分钟，生产出纺织增强输送带。分析了硫化工艺参数对用于增强输送带的织物拉伸性能的影响。此外，还研究了间苯二酚 - 甲醛 - 乳胶对聚酯/聚酰胺66机织物（EP织物）浸渍过程对其拉伸性能的影响。研究结果表明，输送带骨架的拉伸强度受硫化温度的显著影响。在160℃硫化35分钟的输送带显示出最佳拉伸强度，分别比在140℃和220℃硫化35分钟的样品高2.22%和89.06%。此外，无论硫化持续时间如何，在220℃硫化的输送带的拉伸强度和断裂伸长率几乎都被破坏。
