催化剂颗粒的抗压强度测试
测试需求
催化剂广泛用于工业过程中,其中产量和时间问题对于尽快形成产品至关重要。它们降低了特定反应所需的活化能,并经常通过在相对较低的温度下进行来加快反应速度。
为了有效地运行,催化剂不仅需要优异的吸附性能,而且还需要良好的物理强度特性。多孔粒料的机械故障会导致形成小的碎片和细小颗粒,从而造成流体流动阻塞,反应器两端的压降不可接受以及传热变化。因此,确定固体催化剂的机械强度是确保可靠和有效的反应过程的关键参数之一。

翻盖力测试
要求一种可重复的测试系统,用于检查翻盖盖的打开力,可容纳3个不同直径的盖,且夹具更换次数最少。防止称重传感器意外损坏也是前提条件,因为这以前是Betts Ltd的问题。解决方案Mecmesin为该问题提供了完整的解决方案,为每个盖子直径制造了一个心轴系统,该系统将盖子的翻转部分定位在称重传感器下方的正确位置。与贝茨集团海外工厂进行的对比测试花费了时间,以证明测试系统的准确性和可重复性。

网球压缩测试
要求ITF(国际网球联合会)邀请Mecmesin投标一个项目,以替换其过时的“ Stevens”测试机,该测试机用于测量“挤压”网球的力。该规范是在与ITF协商后制定的,目的是提供一种全自动的气动拾放机。在准备测试之前,需要对每个球进行锻炼或“打碎”一定长度。

Compression
Compression testing is a way of determining how something will react when a compressive force is applied to it. It typically involves measuring the relationship between the applied force and how much the object deforms.
It is performed to:

服装纽扣拉脱TTF测试
要求该客户是英国主要服装零售商Marks&Spencer的供应商,后者规定所有紧固件和附件必须经过测试才能失效。接头/纽扣的强度对于确保其满足设计公差和安全水平至关重要,特别是在婴儿服装中。将测试速度的电动单元定义为200 mm / min,因为该系统需要在生产环境中易于使用并提供一致的结果。解决方案将布材料夹在50毫米宽的表面上并涂有防滑橡胶的“双作用虎钳”中,以增强抓地力。

ISO 11608-3 预装药筒的松脱和保持力测试
测试需求
与传统的小瓶和注射器相比,用于递送药物(例如胰岛素)的笔式注射器已经获得专业的认可。注射笔的优化设计易于使用,在递送小剂量的同时提供了更高的准确性,同时患者的注射疼痛也有所减轻。为了验证新的笔式注射器设计并在批量生产时保持一致的质量,需要进行大量力学测试。
