The UV aging test box is suitable for accelerated aging test by light water exposure to predict the relative durability of non-metallic materials such as paints, coatings, and plastics. It is especially suitable for observing the physical property damage of particularly durable materials, such as reduced gloss, haze, reduced strength, Powdering, cracking, blistering, embrittlement and fading.
紫外加速老化試驗箱使用說明：
同其它實驗室加速試驗一樣，不能利用本裝置的試驗結(jié)果替代天然曝曬來判定材料的實際耐久年限，但本裝置提供的對比試驗條件，對快速評估材料的抗老化性能、篩選或改進新老配方、監(jiān)控產(chǎn)品質(zhì)量是相對實用的。
由于紫外光是造成戶外產(chǎn)品耐用度下降的主要光照因素，加上熒光燈管相對穩(wěn)定的光譜能量分布和低廉的價格，紫外光老化試驗箱以快捷、便利和經(jīng)濟的優(yōu)勢成為世界上目前使用為廣泛的耐候測試機種。本裝置作為簡易機型，特別適合經(jīng)濟條件有限的實驗室選用。
Instructions for UV aging test box:
As with other accelerated laboratory tests, the test results of this device cannot be used instead of natural exposure to determine the actual durability of the material, but the comparative test conditions provided by this device can quickly evaluate the anti-aging properties of materials, screen or improve new and old formula Monitoring product quality is relatively practical.
As ultraviolet light is the main lighting factor that causes the durability of outdoor products to decrease, coupled with the relatively stable spectral energy distribution of fluorescent tubes and low prices, the ultraviolet light aging test box has become a widely used in the world with its fast, convenient and economic advantages Weathering test models. As a simple model, this device is especially suitable for laboratories with limited economic conditions.
紫外加速老化試驗箱結(jié)構(gòu)與工作原理：
采用的旋轉(zhuǎn)樣板架設(shè)計可以很好地補償由于燈管老化和各批次差異等諸多因素帶來的光輻射不均勻缺陷，省卻了一般儀器需定期按順序互換樣板位置的繁重工作量。
由于水分是加速老化的重要破壞因素，本裝置采用水噴淋方式模擬濕氣的影響。通過對噴淋時間的設(shè)定，可以比較接近某些最終使用的環(huán)境條件，如溫度劇變或雨水沖刷所造成的機械侵蝕等。
本裝置的LUV型還可以在適當(dāng)范圍內(nèi)通過溫控機構(gòu)調(diào)節(jié)光化反應(yīng)的速率。
為滿足耐候測試機堅固耐用的使用要求，本裝置結(jié)構(gòu)件普遍采用了耐蝕不銹鋼材料。設(shè)計上力求結(jié)構(gòu)簡單、便于使用和維修。只需付出相對低廉的使用成本，就可使您在短時間內(nèi)了解自然條件下長時間才能形成的材料損害，判定試驗產(chǎn)品與對照樣板之間的品質(zhì)差距。
Structure and working principle of UV aging test chamber:
The rotating sample frame design can well compensate for the uneven light radiation defects caused by many factors such as aging of the lamp tube and the difference between batches, which saves the heavy workload of ordinary instruments that need to periodically switch the sample position in sequence.
Since moisture is an important destructive factor for accelerated aging, this device uses water spraying to simulate the effects of moisture. By setting the spray time, it can be closer to some end-use environmental conditions, such as sudden temperature changes or mechanical erosion caused by rain.
The LUV type of the device can also adjust the rate of the photochemical reaction through a temperature control mechanism within an appropriate range.
In order to meet the rugged use requirements of the weather tester, corrosion-resistant stainless steel is commonly used in the structure of this device. Designed to be simple in structure, easy to use and maintain. You only need to pay a relatively low cost of use, so that you can understａnd the material damage that can form under natural conditions for a long time in a short time, and judge the quality gap between the test product and the control sample.

LUV-II紫外加速老化試驗箱注意事項:
★具有高輻照度水平的UVB光源，雖然能大度地加速試驗進程，但有時也會對某些材料造成甚于天然曝曬的老化破壞，如過度變色。所以在評判與對照樣板有差異的試樣時，應(yīng)注意這一因素。

Note for LUV-II UV accelerated aging test box:
★ UVB light source with high irradiance level can greatly accelerate the test process, but sometimes it will cause aging damage to certain materials, such as excessive discoloration. Therefore, we should pay attention to this factor when judging the samples that are different from the control samples.
★ Do not use uncertified non-dedicated lamps.
★ Full-time duty personnel should be equipped to monitor the aging and safety status during the full test of the test.
★ The warehouse door must be opened or the lamp must be replaced with the power off.
★ When not wearing goggles, do not directly observe the lit UV lamp with the naked eye. To prevent skin burns.
★ If the water level drops significantly or the water level of the LUV type test box is shining, deionized water should be added in time to avoid the pump running in the anhydrous state.
★ The test area is not clean and does not use deionized water, it will generate water stains on the sample that hinder observation, and also affect the service life of equipment components.
★ During the entire test, the cooling fan on the electrical box should be ensured to operate normally.
★ To prevent inexperienced non-** personnel from randomly touching the random instrument.
★ Control samples should be installed in the axisymmetric position of the turntable respectively to obtain equivalent lighting conditions.
★ This device is a thin plate-intensive mechanism. Pay attention to safety and prevent abrasion during operation and maintenance.
