膠（jiāo）帶老化（huà）試驗箱HD-E704可做二種測試：老化（huà）與耐黃變，老化：本機可促進加硫橡膠之劣化，以計算加熱前後拉力及伸長之變（biàn）化率，耐黃：本機是模擬大氣（qì）環境中，受陽光紫外線（xiàn）照射，外觀變化一般認為在50℃下測試9小（xiǎo）時。

膠帶（dài）老化（huà）試驗箱簡（jiǎn）介 product description:

本產品可做二種（zhǒng）測試：老化（huà）與耐黃變
老化：本機可促進加硫橡膠之劣化，以計算加熱（rè）前後拉力及伸長之變化率，一般（bān）認為在70 ℃下測試一天，理論上相當（dāng）於暴露在大氣中6個月的時間。
耐黃：本機是模擬大氣（qì）環境中（zhōng），受（shòu）陽光紫（zǐ）外（wài）線照射，外觀（guān）變化一般認為在50℃下測試9小時，理論上相當於暴露在大氣中（zhōng）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.
