Detailed introduction:

  粘扣带疲劳性测试仪为粘扣带性能测试的一部分。通过一定次数圈面与钩面的离合, 测量器剪切强力与剥离强度,模拟其实际使用过程,考量其耐用程度。

  

  1.1测试原理

  

  测试原理

  

  分别将粘扣带的圈面和钩面固定于不同的滚轮表面。试验过程中,滚轮滚动,粘扣带不断发生粘合与剥离。一定次数后取下,进行后续试验。

  

  测试标准

  

  此款粘扣带疲劳测试仪符合下列标准:

  

  1.GB/T 23315

  

  2.DIN 3415

  

  3.SATRA PM 123

  

  技术规格

  

  1.滚轮直径:上轮(从动轮)¢162.5mm,下轮(主动轮)¢160mm

  

  2.滚轮宽度:70mm

  

  3.滚动速度:60rpm

  

  4.反转时间:30s反转

  

  5.荷重:5kg

  

  6.计数器:LCD液晶显示,0-999999

  

  7.电源:AC 220V 50HZ 5A

  

  8.外型尺寸:70×47×60cm

  

  9.重量:51kg

  

  仪器简介

  

  仪器组成

  

  整机主要由以下部分组成,如图1所示:

  

  图1. 整机图

  

  1.配重砝码:与从动轮配套使用,压力为5kg。

  

  2.主动轮:直径为160mm,由电机带动旋转,转速为60rpm,每30s换向反转。圈面固定在主动轮上。

  

  3.从动轮:直径为162.5mm,由主动轮带动旋转。钩面固定于从动轮上。

  

  4.计数器:设定及显示运动圈数。

  

  5.按键:包括急停按键,开始及暂停键。

  

  以GB/T 23315为例介绍试验步骤。

  

  从1副粘扣带上裁切出长度为(540±10)mm,宽度不超过切槽长度的2组试样,每组试样包含一段钩面带和1段圈面带。

  

  在每段钩面带和圈面带上分别标记长度为(100±5)mm的4块区域,并在每块区域的一端标记“1”,另一端标记“2”。

  

  任取1组试样,将标记好的圈面带环绕贴合在小滚轮上,毛面背对滚轮,钩面带环绕贴合在大滚轮上,钩面背对滚轮,使试样与滚轮平行并吻合。确保滚轮在旋转后试样能在整个有效宽度上粘合。

  

  调整计数器,运行试验装置,使试样离合1000次或3000次后取下试样。

  

  沿标记线将试样剪切成4段,测定4组试样的剪切强度,取4组测定结果的算术平均值为该副粘扣带离合1000次或3000次后的剪切强度。

  

  取第2组试样再次进行一次试验。

  

  沿标记线将试样剪成4段,测定4组试样的剥离强度,取四组测定结果的算术平均值为该副粘扣带离合1000次或3000次后的剥离强度。
