Lab UV testing machine

This device is suitable for predicting the relative durability of non-metallic materials such as paints, coatings, and plastics through light-water exposure accelerated aging tests. 

It is especially suitable for observing the physical property damage of particularly durable materials, such as gloss reduction, haze, strength reduction, and powdering. , cracking, blistering, embrittlement and fading, etc.

• Like other laboratory accelerated tests, the test results of this device cannot be used to replace natural exposure to determine the actual durability life of materials. However, the comparative test conditions provided by this device are useful for quickly evaluating the anti-aging properties of materials and screening or improving new and old formulas. , monitoring product quality is relatively practical.

• Since ultraviolet light is the main lighting factor that causes the durability of outdoor products to decrease, coupled with the relatively stable spectral energy distribution and low price of fluorescent tubes, ultraviolet weather resistance test chambers have become the most commonly used in the world due to their advantages of speed, convenience and economy. A wide range of weather resistance testing machines. As a simple model, this device is especially suitable for laboratories with limited economic conditions.

• The rotating sample rack design adopted by this device can well compensate for uneven light radiation defects caused by many factors such as lamp aging and batch differences, eliminating the heavy workload of regular instruments that require regular exchange of sample positions in sequence. 

• Since moisture is an important damaging factor that accelerates aging, this device uses water spraying to simulate the influence of moisture. By setting the spray time, it can be closer to certain end-use environmental conditions, such as mechanical erosion caused by drastic changes in temperature or rainwater erosion.

• This device can also adjust the rate of photochemical reaction within an appropriate range through a temperature control mechanism.

• In order to meet the requirements of strong and durable use of weather resistance testing machines, corrosion-resistant stainless steel materials are generally used for the structural parts of this device. The design strives to be simple in structure, easy to use and maintain.

• With a relatively low cost of use, you can understand the material damage that takes a long time to occur under natural conditions in a short time, and determine the quality gap between the test product and the control sample.
