Rubber products are everywhere - tires, seals, seals, cable sheathing... They silently perform key functions such as shock absorption, sealing and insulation. But you know what? Seemingly durable rubber, in fact, the most afraid of the sun's ultraviolet rays. How to accurately detect the anti-aging properties of rubber? LIB's UV aging test chamber is ideal.
The aging of rubber is essentially the structural destruction of polymer materials under the action of external environment. Ultraviolet light (UV) in sunlight, especially ultraviolet light with a wavelength of 200-400nm, is the main culprit of rubber aging. When UV light irradiates the rubber surface, it triggers a series of chemical reactions:
Molecular chain break: ultraviolet energy destroys the chemical bonds in rubber molecules, resulting in decreased elasticity, hardening and brittleness;
Oxidation reaction: Oxygen in the air enters the void, combines with the broken molecular chain, accelerates the aging of the material, cracks, fading and other phenomena;
Temperature synergy: High temperature will further exacerbate the damaging effect of UV light, doubling the aging rate.
Faced with the challenge of UV aging, LIB brand launched UV aging test chamber
 | Model：UV-SI-260 Specimen Holder Size(mm):75*150 Specimen Capacity:56 Pieces Irradiation Source:Fluorescent UV lamps (8) - 40 W Temperature Range:Ambient ～ 90 ℃ ±2℃ Black Panel Temperature (BPT):35 ～ 80 ℃ Humidity Range:≥95% RH Bandwidth:290 ~ 400nm Irradiance Control:0.3~20 W/㎡ Water Spray Cycle:1~9999H59M (Adjustable) Distance of Specimen and lamp:50mm |
The LIB UV aging test chamber uses high-precision UV fluorescent tubes (optional UVA-340, UVB-313 and other wavelengths), which can accurately simulate ultraviolet rays in different bands of sunlight (such as UVA long wave ultraviolet rays commonly seen outdoors, or UVB short wave ultraviolet rays that accelerate aging).
The device supports the adjustment of temperature (up to 80 ° C), humidity (30%-98%RH), and light cycle (0-24 hours free setting).
The LIB UV aging test chamber is equipped with intelligent control system, and the light intensity is stable.
Compared with similar products, its energy consumption is 20% lower, the lamp life is more than 1600 hours, and the long-term use cost is lower.
The anti-aging properties of rubber determine the service life and safety of the product. The LIB brand provides a one-stop service: free installation and commissioning, operational training, as well as a 3-year warranty and lifetime maintenance, so that you have no worries. Contact us now to get:
