ASTM D4587 UV Aging Test Chamber Lab Weathering Testing Machine
Battery Sprinkler
Equipment Summary:
This device is suitable for predicting the relative durability of
paints, coatings, plastics and other non-metallic materials through
light and water exposure accelerated aging tests, and is
particularly suitable for observing the destruction of physical
properties of particularly durable materials, such as gloss
reduction, fog shadow, strength reduction, chalking, cracking,
blistering, brittleness and fading.
As with other accelerated laboratory tests, the test results of
this device cannot be used as a substitute for natural exposure to
determine the actual durability of a material, but the comparative
experimental conditions provided by this device are relatively
practical for quickly assessing the aging resistance of materials,
screening or improving new and old formulations, and monitoring
product quality.
Since UV light is the main light 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 tester has become the most widely used weathering test
machine in the world with the advantages of speed, convenience and
economy. As a simple model, this device is especially suitable for
laboratories with limited economic conditions.
The design of rotating sample frame adopted by this device can
compensate for the uneven light radiation defects brought by many
factors such as lamp aging and differences between batches, which
saves the heavy workload of changing the sample positions regularly
in order of general instruments.
As moisture is an important destructive factor to accelerate aging,
this device uses water spray to simulate the influence of moisture.
By setting the spraying time, it can be closer to certain end-use
environmental conditions, such as mechanical erosion caused by
drastic changes in temperature or rain.
This model also allows the rate of photochemical reaction to be
adjusted within the appropriate range by a temperature control
mechanism.
In order to meet the requirements of the weathering tester's robust
and durable use, the structural parts of this device are generally
made of corrosion-resistant stainless steel. The design strives for
simple structure, ease of use and maintenance.
Only a relatively low cost of use will enable you to understand in
a short period of time the damage to the material that can only be
formed under natural conditions for a long time, and determine the
quality gap between the test product and the control sample.
