  耐刮伤性试验仪简介

  

  耐刮伤性试验仪其应用领域包括:刚性有机材料、涂料黏胶剂、粉末涂料,阳极氧化材料,软金属,塑料和玻璃等,也能用于测试同种材料、防护涂料的粘胶剂质量及类似材料的极限性能。仪器由平衡杆、固定砝码、调节砝码、载样圆盘等组成。试验前需根据试样的厚度调节平衡杆的高度,使平衡杆中部安装刮擦头并且试样安装于载样圆盘后,平衡杆能够保持水平。试验过程中,固定砝码不动,移动调节砝码控制压在试样上的重量。随着载样圆盘的逆时针旋转,刮擦头在试样表面留下弧形刻痕。

  

  1.1 测试标准

  

  此款耐划伤测试仪仪符合下列标准:

  

  lAS/NZS AS2924.2

  

  lASTM C217

  

  lBS EN 438.2

  

  lBS EN 13310

  

  lBS EN 14323

  

  lDIN 68861-4

  

  lDIN 53799

  

  lAS/NZS AS2924.2

  

  lASTM C217         GB/T15102

  

  lBS EN 438-2         GB/T17657

  

  lBS EN 13310:2003

  

  lBS EN 14323

  

  lDIN 68861-4          GB/T18102

  

  lDIN 53799

  

  BS EN 14688:2006

  

  TSF7365 5.2.12-2009

  

  1.2 测试原理

  

  将试样放置于厚度控制装置凹槽内,调节螺母位置。将试样安装在可旋转圆形平台上,并用压块及螺母固定。将刮擦头安装与秤杆中部对应凹槽内。旋转平衡杆,使刮擦头头部与试样刚好接触。启动仪器,圆盘运动,刮擦头在试样表面留下刮痕。

  

  1.3 仪器结构与功能

  

  平衡杆调节部件:本部分包括厚度控制装置,高度调节螺母,前后位置调节螺母,平衡杆组成。平衡杆的高度由试样的厚度决定。试验前将试样插入厚度控制装置凹槽内,通过调节高度调节螺母,使试样恰好卡在凹槽内。当试样安装于圆形载样平台,摩擦头装入平衡杆后,其头部顶住试样,此时,平衡杆基本保持平行,只需微调即可(放置水平泡看是否水平)。

  

  部分标准中要求试验结果为不同半径的同心圆,调节前后位置控制螺母控制刮擦头与载样

  

  圆盘中心的距离,从而产生不同半径的刻痕。

  

  压力调节部件:本部分包括固定砝码,移动砝码,平衡杆。平衡杆上标有0-500的刻度,每一格代表10g压力。使用时,移动砝码中间刻线对准平衡上刻度线,则在试样表面施加的压力为刻线所示压力。

  

  载样部件:本部分由载样圆盘,固定片,固定螺帽组成。将试样放置在载样圆盘上再用固定片压住,用螺母固定即可。

  

  控制部件:包括计数器、启动按钮、暂停按钮及电源开关组成。

  

  试验步骤

  

  试样制备,标准中试样尺寸为100mm*100mm的正方形片,四周棱角,中部开有一直径为6.5的开孔,如下图所示

  

  将试样放入厚度控制装置处,调节上端螺栓使试样的上表面和厚度控制装置的下表面接触。

  

  取下试样将试样将其放在测试盘上,拧紧试样上面的螺帽,放下平衡杆,将水平气泡放于平衡杆上,看平衡杆是否水平,如若没水平则需调节后端螺栓使其气泡达到水平

  

  移动右端砝码到需要的压力位置,拧紧砝码后端的螺栓使其在运行过程中不发生移动。

  

  通电,选择实验的运行圈数,按下开始按钮,进行试验。

  

  Taber 551刮伤试验仪在装样品之前,需要先根据样品厚度调整秤杆至合适高度。在秤杆上的安装好精密切削工具并置于样品上。启动仪器,转台以恒定转速转动确保测量结果准确。通过改变切削工具的荷重,您可以评估材料的抗剪切或者刮伤性能。

  

  Taber 551刮伤试验仪仪器的秤杆设计使得它能够与样品和转台水平,并且可以根据实际需要要升高或者降低。另外,秤杆还可以抬起悬于空中以方便操作者移走样品。通过改变滑动砝码的位置,样品上的总荷重在0-1000g范围可调整。切削工具可以选择使用碳化钨刀具或者圆锥形钻石头。

  

  Taber 551刮伤试验仪测试结果可用随机配备的10倍放大镜目测判定,用户也可使用高精度光学显微镜观测
