一、适用范围 本标准适用于热双金属。由于热双金属能够多方面地应用于温度敏感元件,例如测量和调节装置等,所以它已在工业技术领域中得到了广泛的应用。 二、概念、特性 2.1热双金属 热双金属是一种双层复合材料,它一般由两层热膨胀系数不同,厚度大致相同的材料相互牢固结合在一起所组成的复合材料。以下称单层材料为组元层。因此当温度发生变化时,原先平直的热双金属直条就会弯曲
First, the scope of application This standard applies to hot double metal. Since the thermal bimetal can be widely applied to temperature-sensitive elements such as measuring and regulating devices and the like, it has been widely used in the field of industrial technology. Second, the concept of the characteristics 2.1 Hot bimetallic thermal bimetal is a double-layer composite material, which is generally composed of two layers of different thermal expansion coefficient, the same thickness of the material firmly combined with each other composed of the composite material. The following single layer material for the component layer. Therefore, when the temperature changes, the original straight bimetal straight bar will be bent
