Model 432 Smart II
432 Smart II 型梯度炉用于评估漆和粉末涂料、树脂、塑料等的烘烤和干燥特性，可以通过对加热速度、烘烤温度和时间编程来模拟生产过程。它可以实现预测特定涂料系统在不同温度下对特定材料如何反应。该测量具有非常好的可重复性，实现很准确地测定极限值。根据炉子类型，可以在高达 320°C 的温度下对涂层进行测试。如果用双刮板涂漆，可以在一张试片上同时测试两种不同的漆。
目的和应用:
酸雨、鸟粪、燃料、防冻液和许多其他环境因素都会损害汽车漆面。特别是在夏天，有些物质会有很强的侵蚀性，并造成严重的损害。因此，汽车涂料制造商以及汽车制造商需要找出不同的环境现象将如何与涂层系统相互作用。
对于炉灶搪瓷系统的开发和质量测试来说，评估温度范围和最高温度极限是非常重要的，在这个温度范围内，漆料配方的成分（从而也可能是整个产品的性能和质量）开始发生变化。众所周知的主要例子是结合剂的黄变以及颜料的颜色变化。
关于工业生产条件下的烤漆问题，准确控制相应的过程对于实现和持续保持/保证涂层的特定质量特征至关重要。由于不同的原因，实际存在的条件并不总是与预设的工艺运行完全一致，在 "最坏的情况 "下可能会导致严重的不合格成本。
Gradient-oven 432 Smart为有关产品提供了基于需求的工艺优化的可能性。
事先通过炉子温度记录器确定的炉子上釉生产线的 "实际情况"，可以通过以需求为导向设置适当的梯度来进行最佳模拟，从而实现对各自上釉情况近乎完美的1:1模拟，但在所需的实验室规模上，可以节省时间和费用。
