紫外线试验箱

产品用途：

太阳的紫外线是导致所有暴露于户外的产品的材料发生降解的主要原因。长崎TK-ZW系列紫外线试验箱可模拟太阳光中的紫外线部分，可地模拟太阳光中的短波紫外光，即从365纳米到太阳光截止点295纳米的波长范围。特别适用于测试不同种类聚合物和稳定剂之间的性能差异。在短短的几天或几周内，可真实再现因光照引起的产品材料在几个月甚至几年的户外使用所岀现的物理性能的老化和破坏!样品试验的结果为改良产品品质提供了科学依据。

Purpose: the ultraviolet radiation is the main cause for the breakdown of all the products material exposed in the sun The TK-ZW series UV aging test machine can simulate the short wave ultraviolet light in the sunlight. Namely the range of wavelengths from 365 to 295 nanometer. Especially suitable for the text of performance gap between polymer and stabilizer In just a few days or weeks, months or even years of aging and damage due to the ultraviolet radiation can be vividly reflected. The results of the sample text provide a scientific basis for the products quality improvement.

产品介绍：

1、本机具有潮湿模拟功能，开启本功能，即可真实的模拟产品试样在户外潮湿侵蚀的工况。因为在很多户外环境中，产品可能每天的潮湿时间可长达12小时。研究表明造成这种户外潮湿的主要因素是露水，而不是雨水。本机*的加湿器可使试验箱在较高温度下保持99%相对湿度，让水蒸汽连续不断地在样品表面凝结，来模拟户外的潮湿侵蚀。真实的再现了试样使用的各种环境!从而得到最真实的实验结果。

2、本机具有热冲击及应力模拟功能!在某些实际应用条件下，例如阳光下，聚集的热量由于突降的阵雨而迅速消散时，材料的温度就会发生急剧变化，产生热冲击，这种热冲击对于许多材料而言是一种考验。本机采用的德国“西门子"PLC控制器可自动或手动程式模拟热冲击和应力腐蚀工况。

3、可根据不同的测试条件，有二种不同的紫外灯管可选择更换。即UVA-340灯管和UVB-313灯管（注:UVA-340灯管可地模拟太阳光中的短波紫外光，即从365纳米到太阳光截止点295纳米的波长范围。特别适用于测试不同种类聚合物和稳定剂之间的性能差异。UVB-313灯管主要用于质量控制和研究开发，或对耐候性的材料运行测试）

1、Humidity impersonation function allows you to forge a real outdoor wet corrosion condition. because under most outdoor situations, the products may be in moist for 12 hours or more. Study has shown that this outdoor moist situation is caused by the dew, rather than the rain. The unique humidifier could help maintain a 99%relative humidity condition in the text box, which could make the stem consistently condense on the samples So as to create the outdoor wet corrosion.Vividly reflected all the situation of all the samples that s how we gonna get the most updated and real test results.

2、Heat shock resistance and stress simulation On some situations Like under the sunlight. When the gathered heat rapidly fade away due to the sudden rain, material temperature will declare sharply. which gonna lead to thermal shock. It would be a challenge for most materials. This machine adopts German "Siemens"PLC controller. It can automatically or manually programming simulation of thermal shock and stress corrosion condition.

3、Two different UV lamps for choose on different text conditions The nva-340 tube and NUV-313 tube(PS: NVA-340 could simulate the short wave ultraviolet light namely the range of wavelengths from 3 65 nanometer to 295 nanometer.expecially suitable for the text of performance gap between polymer and stabilizer. UVB-313 tube mainly focus on the quality control and research development or the text for the high weather ability material.
