Shoe Material Yellow Aging Resistance Test Chamber

Product Details

Product Description

Product Description
Anti-yellowing aging test chamber can do two kinds of testing:aging and anti-yellowing.
Aging:the machine can promote the increase of sulfurrubber deterioration,to calculate the change rate of tensile andelongation before and after heat.It is generally thought that testfor one day at 70℃,in theory as exposed to the atmosphere for 6months.
Anti-yellowing:this machine stimulates the atmosphereenvironment,driven by the sun ultraviolet radiation.Itsgenerally thought that the appearance change at 50℃ for 9hours,in theory as exposed to atmosphere for 6 months.
FEATURES
1) To simulate outdoor weathering, the UV aging testersexposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It simulates the effects of sunlight using special fluorescent UV lamps. It simulates dew and rain with condensing humidity and/or water spray.
2) The UV accelerated weathering tester is the simplest, most reliable, and easiest to use weathering tester available. With thousands of testers in use worldwide, it is the world's most widely used weathering tester.

The testing of the yellowing and aging resistance of shoe materials is performed using a specific test chamber that simulates environmental conditions. This evaluates the material's performance after prolonged exposure to UV light, heat, humidity, and other factors. Below is a detailed introduction to the product features, applicable standards, and environmental conditions of the test chamber for shoe material aging resistance:
Product Features:UV Simulation: The test chamber is typically equipped with UV lamps that simulate the UV rays from sunlight to accelerate the aging process of shoe materials. By controlling the intensity of UV light and exposure time, the chamber replicates the aging effect of long-term sunlight exposure on the material.
Temperature and Humidity Control: The test chamber can precisely control the internal temperature and humidity, simulating the aging reaction of shoe materials under high temperature and humidity. The typical temperature range is 40°C to 80°C, with humidity control from 40% to 90%.
Accelerated Aging: By combining high temperature, humidity, and UV light, the chamber accelerates the aging process, allowing for a faster evaluation of the material’s long-term durability.
Automated Control and Monitoring: Modern test chambers feature digital control panels that automatically adjust parameters and display real-time data on the internal environment, ensuring accuracy and stability during testing.
Energy-saving Design: To improve cost-efficiency and environmental sustainability, the test chamber typically uses energy-efficient technologies such as high-performance UV lamps and insulation materials.
Applicable Standards:Testing the yellowing and aging resistance of shoe materials generally follows the standards below:
ISO 105-B02: This standard specifies the method for testing the UV light exposure of textiles to evaluate their resistance to UV-induced aging.
ASTM G154: This is a standard issued by ASTM (American Society for Testing and Materials) for accelerated UV exposure testing, widely used for testing the aging resistance of various materials.
GB/T 11741: This is a Chinese national standard for UV and aging tests on shoe materials and other substances.
EN 13758: This European standard is used to test the UV resistance of textiles and other materials to assess their aging degree under UV exposure.
Environmental Conditions:Ambient Temperature: The test chamber typically operates within an ambient temperature range of 10°C to 40°C, ensuring stable testing conditions.
Power Supply: The chamber usually requires a power supply of 220V ± 10%, 50Hz, though specific models may have different power requirements.
Humidity Range: The humidity inside the chamber should be maintained between 40% and 80% relative humidity, especially during high-humidity tests, to ensure the right environmental conditions.
Ventilation: The test chamber needs a good ventilation system to ensure proper air circulation and stable UV light exposure.
By setting up these conditions and standards correctly, the aging characteristics of shoe materials under simulated environmental conditions can be accurately assessed.
