聚酯钢化棕丝在V带中的应用

Application of Pre-stretched Polyester Monofilament in V-Belt

对比研究聚酯线绳与聚酯钢化棕丝的性能及其在V带中的应用。结果表明:与聚酯线绳相比,聚酯钢化棕丝的直径、断裂强力、断裂伸长率和定负荷伸长率均较小,与天然橡胶间的粘合强度较大,高温下的干热收缩率较大;与成品聚酯线绳V带相比,聚酯钢化棕丝V带的整根拉伸强度和参考力伸长率较小,线绳拔脱强度较大,疲劳寿命延长,经济效益提高。

The properties of polyester cord and pre-stretched polyester monofilament, plication in V-belt were investigated. The results showed that, compared with polyester ameter, breaking strength, elongation at break and elongation at specified load of pre-stre ter monofilament were lower, the dry heat shrinkage at high temperature was higher,and strength between pre-stretched polyester monofilament and NR was higher. Compared nished polyester cord V-belt, the tensile strength and elongation at reference load of th belt by using pre-stretched polyester monofilament were lower, the pull out strength higher,the fatigue lifetime of V-belt was longer,and the economic benefit was improved. and their ap- cord, the di-tched polyes-the adhesion with the fi-e finished V-of cord was
