胶带老化试验箱简介 product description:

本产品可做二种测试：老化与耐黄变
老化：本机可促进加硫橡胶之劣化，以计算加热前后拉力及伸长之变化率，一般认为在70 ℃下测试一天，理论上相当于暴露在大气中6个月的时间。
耐黄：本机是模拟大气环境中，受阳光紫外线照射，外观变化一般认为在50℃下测试9小时，理论上相当于暴露在大气中6个月的时间。

This product can do two kinds of testing: aging and anti-yellowing

Aging: the machine can promote the increase of sulfur rubber deterioration, to calculate the change rate of tensile and elongation before and after heat. It’s generally thought that test for one day at 70℃, in theory as exposed to the atmosphere for 6 months.

Anti-yellowing: the machine stimulate the atmosphere environment, driven by the sun ultraviolet radiation. It’s generally thought that the appearance change at 50℃ for 9 hours, in theory as exposed to atmosphere for 6 months.
