  皮革摩擦色牢度测试仪,试验机  简介

  

  该仪器用于皮革表面摩擦牢度的测试,通过确定皮革表面或涂层的“掉色”程度和羊毛毡的沾色程度来评估颜色的转移情况。试验时,以干燥或湿润的白色羊毛毡,包于摩擦表面,然后往复摩擦夹在试验台上的试片。有干、湿两种测试方式。

  

  测试标准

  

  ISO 11640

  

  QB/T 2882(法A)

  

  QB/T 2537

  

  GB/T 3903.31

  

  GB/T 20991-7.3

  

  测试原理

  

  摩擦头(含或不含外加砝码)上的方形羊毛毡对摩擦平台上的皮革(拉伸或不拉伸)进行往复摩擦,一定次数后对羊毛毡进行沾色灰卡比对,测试皮革进行掉色灰卡比对,评出等级。

  

  仪器由以下几部分组成:

  

  附加砝码:依据各标准要求,附加砝码为500g。

  

  摩擦锤:依据各标准要求,摩擦锤为500g。

  

  摩擦台:试验时承载试样。

  

  电源开关

  

  延伸螺旋旋钮:通过旋转螺旋旋钮使摩擦台面积变大,从而使固定在摩擦台上的试样变形。

  

  计时器:设置并显示摩擦次数。

  

  开始暂停按键

  

  仪器技术参数

  

  仪器尺寸:282mm*460mm*470mm(L*D*H)

  

  测试平台尺寸:150mm*100mm(L*W),长度方向zui大可延伸25%

  

  测试面积15*15mm

  评价

  

  在GB/T 6151规定的人工光源或来自北面的日光下,对比试验后和未经试验的部分。

  

  用相应几何定级的灰色样卡进行定级(即对颜色迁移用“沾色程度”,损伤用“颜色变化”)。

  

  如果评定在两个定级之间。取较低的定级,即,较差的情况。

  

  如果重复试验的定级不同,取两者之间较低的定级作为试验结果。
