全厚度拉伸强度是橡胶输送带检测中最为核心的一项性能指标,关系到成品在实际使用中的寿命,决定其使用安全性。如果一条输送带成品的拉伸强度达不到它的设计要求,实际使用中就可能会发生突然断裂,导致整条输送带报废,甚至出现人身机械事故。因此国家制定了GB/T 3690-2009《织物芯输送带全厚度拉伸强度、拉断伸长率、参考力伸长率试验方法》。而如何正确试验,获得可靠的数据,对输送带的设计、生产等有着积极的指导意义。
Tensile strength of full thickness rubber conveyor belt testing is the core of a performance index related to the life of the finished product in use, to determine the safety of its use. If the finished product of a conveyor belt can not meet the design requirements of its tensile strength, sudden breakage may occur during actual use, resulting in the scrapping of the entire conveyor belt and even a mechanical and mechanical accident. Therefore, the state developed GB / T 3690-2009 “full-thickness fabric conveyor belt tensile strength, tensile elongation, reference force elongation test method.” How to correctly test and obtain reliable data has a positive guiding significance for the design and production of the conveyor belt.
