膠帶老化試驗(yàn)機(jī)：

 HD-E704 耐黃/老化試驗(yàn)機(jī)

HD-E704 Anti-yellowing & Aging Tester

產(chǎn)品簡介 product description:

本產(chǎn)品可做二種測試：老化與耐黃變
老化：本機(jī)可促進(jìn)加硫橡膠之劣化，以計算加熱前后拉力及伸長之變化率，一般認(rèn)為在70 ℃下測試一天，理論上相當(dāng)于暴露在大氣中6個月的時間。
耐黃：本機(jī)是模擬大氣環(huán)境中，受陽光紫外線照射，外觀變化一般認(rèn)為在50℃下測試9小時，理論上相當(dāng)于暴露在大氣中6個月的時間。

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.
