UV Accelerated Weathering Aging Test Chamber
(Horizontal Type)
Model: RC-UV3
Product Introduction:
This device is suitable for the accelerated aging test by exposing to light and water. It is used to predict relative durability of paint, coating, plastic and other non-metallic materials. It is suitable for observing physical properties of durable materials especially, such as gloss reduction, haze, strength reduction, pulverization, cracking, blistering, embrittlement and faded, etc.
Like other accelerated tests in laboratories, we can’t use the test result of this device replace natural exposure to determine actual durable time of materials. But this device is relatively practical on assessing the anti-aging performance of materials rapidly, selecting or improving the new and old formulas, monitoring the quality of products by providing the contrastive experiment conditions.
Ultraviolet light is the main light factor result in durability reduction of outdoor products. Combine with fluorescent tubes possess stable spectral energy distribution and low price, ultraviolet aging test chamber becomes the most popular test chamber in the world because of its quick, convenient and economic advantages.
Because water is an important factor of accelerating aging. This device adopts the way of water spraying to simulate the effect of moisture. It can close to some environmental conditions of final use by setting the spray time, such as temperature change or rain wash result in mechanical erosion.
This model can also adjust the rate of photochemical reactions by temperature control mechanism in the appropriate range. To satisfy the durable demands of weather resistance tester, this device structures adopt corrosion resistant stainless-steel materials widely. Its design is simple, easy to use and maintenance.
You can get to know damages level of materials in a short time and judge the quality gap between test products and reference samples as long as you pay low use cost.
