一,五指刮擦测试仪用途

测试仪广泛用于汽车行业。主要检测汽车内、外饰件中平滑、纹路塑料饰件的耐磨性。除了材料和产品的开发,也适用于质量的控制。五指刮擦/划伤测试仪的设计是为塑料材质评估、坚硬材质耐磨、油漆、油墨、软金属、油地毯、附加件和其它材质的检测本仪器满足多种测试标准,且可根据客户要求自定义试验平台的运动行程、运动速度和往复运动周期。五指刮擦测试仪试验:试验平台上的试样接触五个刮指或1个塑料刮指及其上方施加的砝码重量。试验过程中,试验平台移动,刮指在试样表面留下划痕。根据划痕的深浅判断试样的耐划伤性能。试样可为塑料板、涂有油漆和清漆的测试板等。

二,测试原理

  五指刮擦测试仪试验:试验平台上的试样接触五个刮指或1个塑料刮指及其上方施加的砝码重量。试验过程中,试验平台移动,刮指在试样表面留下划痕。根据划痕的深浅判断试样的耐划伤性能。试样可为塑料板、涂有油漆和清漆的测试板等。

三,技术参数:

  1、行程范围:10-200mm

  2、速度范围:10-200mm/s

  3、速度缓冲:10±1mm

  4、金属刮擦头直径:0.5mm0.75mm1mm(Erichsen318)3mm5mm7mm

  5、金属刮擦头材质:碳化钨使用碳化钨作为刮擦指,合理检测受非常规定义物理形式(如刮、抓、刨削等)破坏的表面磨损情况。

  6、加压砝码及刮擦组件总重量:2N3N5N7N8N10N12N15N20N (可任意配选)质量误差不超出 1%另外可选配定制砝码

  7、塑料刮指:聚甲基丙烯酸甲酯(PMMA)直径 16mm 厚度 1mm刮指边缘的半径为 0.5mm 硬度为 shore D852

四,测试标准

  五指此款符合下列标准:

  FORD FLTM BN 108-13

  GMW 14698(B)

  FORD BO-162-01

  五,在刮擦测试结果的评价上,常见的测试方法上可以划分为目视的评价方法和仪器的评价方法:

目视的评级方法是将试验后的样品放置在北部天空日光或D65人造光源的照明下,试验样品相对于评价者处于水平状态,必要时对样品进行旋转以获得最jia的观察角度,对于直线型的   刮擦,在评价过程中只评价中间的80%的部分。评价内容主要包括表试验样品表面是否有损伤性划痕、材料是否变形,是否产生开裂、发毛等现象。根据材料的不同,在评价等级上标准也相应有所不同。

仪器评级方法主要根据光学检测仪器来评价试验样品的颜色和光泽变化。

a、颜色变化。有不同的测量方法和考察指标,例如,按照ISO 7724一或其他类似标准规定的方法,采用CIELAB色度空间,在10°观察者、D65照明光源、包含境面光泽成分、积分球测量几7724-2或其他类似标准规定的方法,采用CIELAB色度空间,在100观察者、D65照明光源、450/000°/45°的测量几何等条件下测量试验样品刮擦后部位与未刮擦部位的颜色变化即△L*△a* ,△h*以及色差△E*

b、光泽变化。按照ISO 2813或其他类似标准规定的方法,测量试验样品刮擦后部位与未刮擦部位的600200镜面光泽变化。
