Detailed introduction:
  1. 百格十字耐刮擦测试仪用途范围

    百格十字刮擦测试仪本仪器适用于各种汽车用内饰材料,如塑料、橡胶、皮革、织物、涂层材料、非涂层材料及其他复合材料等的耐刮擦性能检测。耐刮擦仪是适用各类汽车内饰材料刮擦性能测试仪器,仪器集成国内三个测试标准(五指刮擦法、百格法、塑料刮指刮擦法)。百格十字刮擦测试仪本测试方法是用来测试表面材料抵抗由刮指引起伤害的能力。

     

    二,百格十字符合下列标准:

      GM 14688(A)     

      GM 14688(B)

    Pv 3952大众标准

    Q/SQR S1-16-2016 奇瑞标准

    Q/SQR T1-64  奇瑞标准

      GB/T 9286-97/ISO 2409ISO2409

      GB/T 9279-2007/ISO 1518:1992

    三,仪器特征:

      1. 仪器由电机驱动机构、刮擦组件、样品夹持固定装置等组成。

      2. 刮擦组件包括刮擦支架、刮指、刮指定位套、加压装置(砝码及砝码支撑杆)等。

      3. 仪器可自由安装、更换、拆卸不同规格的刮指,能够在不同负荷下实施匀速单向直线刮擦运动。

      4. 采用嵌入式系统、人机界面操作对测试流程进行自动化控制,采用精密的伺服电机、滚珠丝杠传动,对于在相关标准下的刮擦速度控制具有决定性的作用。

      5. 采用碳化钨材质做刮指,增加仪器适用寿命。

      6. 采用铝合金及不锈钢材质,外观简洁轻便且耐腐蚀。

    四,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:0.5mm0.75mm1mm3mm5mm7mm;

      5. 金属刮擦头材质:碳化钨,蓝宝石,硬质合金;

      6. 加压砝码及刮擦组件总重量:5N10N,,15N

      8. 电源:AC220V±10%50Hz

      百格法刮擦试验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,测试原理

      百格法刮擦试验:试验目的为检测涂料的耐刻痕脱落性能。普通的百格法为手动测试,操作费时费力。本仪器使用中,通过两个电机驱动,控制划痕的长度、划痕与划痕之间的距离。运动过程为:第yi阶段试验,往复移动平台运动一次(半圈),气缸使刮擦指抬起,电机带动刮擦指纵向移动一定距离,气缸使刮擦指放下,然后往复移动平台再运动一次(半圈),气缸使刮擦指抬起,电机带动刮擦指纵向再次移动一定距离,如此反复。当划完指定的条数后,手动将测试板旋转90度,进行第二阶段试验后完成试验。本仪器可以实现划格间距2.0mm,满足标准的要求。

    六,配置:

      1.试验模块:百格法刮擦(或称十字划格,以下统称为百格法刮擦)模式

      2.往复移动平台移动距离:10-200mm可调

      3.往复移动平台移动速度:10-200mm/s可调

      4.刮擦指移动间距:0.5mm, 1mm, 2mm可调

      5.刮擦试验负荷:5,10N, 15N

      6.气缸控制百格刮指的下降与抬起

      7.电源:AC 220V 50HZ

      8.外形规格:662mm*360mm*657mm(W*D*H)

      9.重量:75kg

    七,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和光泽变化。

    a、颜变化。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、积分球测量几何等条件下,用测se差仪测量试验样品刮擦后部位与未刮擦部位的明度变化即明度差△L*,按照ISO 7724-2或其他类似标准规定的方法,采用CIELAB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变化即△L*△a* ,△h*以及△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。
