Embodiment Construction
[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0014] 本发明实施例通过太阳光中紫外成份所占的能量以及紫外灯发出的紫外辐射能量来计算出加速因子,并由待测样品的预期寿命推算出加速寿命测试所需的时间,从而加速测试待测样品的寿命,节约产品的研发及生产时间。
[0015] 下面以橡胶为例对本发明的实现进行详细描述, figure 1 示出了本发明实施例提供的加速寿命测试方法的实现流程。
[0016] 在步骤S101中,选取待测样品,测试并记录其性能参数;
[0017] 寿命测试前,选取同一批次的多个待测样品,对各待测样品进行测试并记录其性能参数,如橡胶的硬度、颜色等,又如待测样品为亚克力时,其性能参数为硬度、强度和透光率。同时预留部分待测样品,于寿命测试后,与寿命测试样品进行比对,以便进行失效分析、可靠性分析等。
[0018] 在步骤S102中,根据待测样品实际使用环境,选择相应的紫外灯作为紫外测试仪器的光源;
[0019] 目前,用来模拟测试待测样品寿命的紫外灯有三种类型:
[0020] UVA-340型紫外灯,该种灯的紫外辐射峰值为340nm,其紫外辐射区域为对非金属材料的光化学反应有重要影响的短波区域,与户外阳光相符;
[0021] UVA-351型紫外灯,该种灯的紫外辐射峰值为351nm,多数用来模拟太阳光透过窗玻璃后的情况;
[0022] UVB-313型紫外灯,该种灯的辐射包括相当一...
