分层输送带全厚度拉伸强度稳定性的控制

Control of Total-thickness Tensile Strength Test for Multi-layer Conveyor Belt

分析分层输送带全厚度拉伸强度稳定性的影响因素,主要包括结构设计(骨架材料类型、浸胶帆布层数)、帆布的使用情况、生产工艺、生产设备和特殊生产环境,排查了引起分层输送带全厚度拉伸强度不合格的原因。通过对分层输送带全厚度拉伸强度质量控制的研究,大幅度减少了分层输送带拉伸强度不合格的产品数量。

In this study,the factors influencing the stability of the total-thickness tensile strength of the multi-layer conveyor belt were analyzed. The factors included structural design（ reinforcement material type and number of dipped canvas layers）,application method of dipped canvas,production technique and equipment,and special operation environmental parameters. The root causes for off-specification of the total-thickness tensile strength were analyzed. Based on that,the quantity control was improved and the percentage of off-spec product was significantly reduced.
