Quickly Assess UV Accelerated Aging Test Chamber , Convenience and
Economy
Product introduction:
The device is suitable for accelerating aging test by light and
water exposure, predicting the relative durability of non-metallic
materials such as paint, paint, plastic, etc. It is especially
suitable for observing the physical property damage of particularly
durable materials, such as gloss reduction, haze, strength
reduction, powder. Chemical, cracking, foaming, embrittlement and
fading.
As with other laboratory accelerated tests, the actual test results
of the device cannot be used instead of natural exposure to
determine the actual endurance of the material. However, the
comparative experimental conditions provided by the device can
quickly assess the anti-aging properties of the material, screen or
improve the old and new formulations. Monitoring product quality is
relatively practical.
Because ultraviolet light is the main lighting factor that causes
the durability of outdoor products to decline, coupled with the
relatively stable spectral energy distribution and low price of
fluorescent tubes, the UV aging test chamber has become the most
widely used in the world with its advantages of speed, convenience
and economy. The weathering test model. As a simple model, this
unit is especially suitable for laboratories with limited economic
conditions.
The rotating model frame design adopted by the device can well
compensate for the unevenness of the optical radiation caused by
many factors such as the aging of the lamp and the difference of
the batch, and the heavy workload of the general instrument to
periodically exchange the position of the template in order. .
Since moisture is an important destructive factor for accelerated
aging, the device uses a water spray method to simulate the
influence of moisture. By setting the spray time, it can be closer
to certain end-use environmental conditions, such as sudden changes
in temperature or mechanical erosion caused by rain wash.
This model can also adjust the rate of photochemical reaction
through a temperature control mechanism within an appropriate
range.
In order to meet the demanding requirements of the weathering
tester, the structural components of the device are generally made
of corrosion-resistant stainless steel. 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 can be formed under natural conditions for a long time,
and determine the quality gap between the test product and the
control sample.
