紫外线涂料加速耐候性试验机图片
用途:采用荧光紫外灯为光源,通过模拟自然阳光中的紫外辐射和冷凝,对材料进行加速耐候性试验,以获得材料耐候性的结果。 本机用于非金属材料、有机材料(如:涂料、油漆、橡胶、塑胶及其制品),经在阳光、湿度、温度、凝露等气候条件的变化下检验有关产品及材料老化现象程度。在短时间内得到变色,退色等情况。
符合标准:GB/T14522-93 GB/T16422.3-1997 GB/T16585-96;等现行紫外线老化试验标准;
光源:
1、光源采用8支额定功率为40W的紫外荧光灯作发光源。紫外线荧光灯 管,分布在机器的两侧,每侧各4支。有UVA-340和UVB-313光源供用户选择配置。(任选一种)
2、UVA-340灯管的发光光谱能量主要集中在340nm的波长处
3、UVB-313灯管的发光光谱主要集中在313nm波长附近。
4、由于荧光灯光能量输出会随时间而逐步衰减,为了减小因光能量衰减造成试验的影响,所以本试验箱在所有的八支灯管中每隔1/4的荧光灯寿命时,由一支新灯管替换一支旧灯管,这样,紫外光源始终由新灯和旧灯组成,从而得到一个输出恒定的光能量。
5、灯管有效使用寿命可在500小时左右(进口灯管1600~1800小时左右。)

Light Source:
1, Using 8pcs UV fluorescent lamps with 40W power rating as light source. UV fluorescent tubes are distributed on both sides of the machine, each side has 4pcs. It has UVA-340 and UVB-313 optional for customers’ configuration. (Option one type)
2, UVA-340 lamp luminescence spectra energy is mainly concentrated in the 340nmof wavelength.
3, UVB-313 lamp luminescence spectra is mainly concentrated near the 313nm of wavelength.
4, Due to fluorescent light energy output will gradually decay over time, in order to reduce the test effect because of light energy attenuation, when in every 1/4 of the fluorescent lifetime of eight lamps in the chamber, a new lamp will replace an old lamp, thus UV light source is always formed by new lamp and old lamp, to get a constant output of light energy.
5, the effective useful life of the lamp is about 500 hours (imported one is about 1600~1800 hours).
Standard: GB/T14522-93 GB/T16422.3-1997 GB/T16585-96; and other current UV aging test standards.
