In our daily lives, both humans and objects will be affected by the environment and age. This aging process is often dominated by the three elements of water, sunlight and water. Light, temperature and water. Any one of these three factors will cause material aging, and their combined effect is greater than the harm caused by any one of them.

illumination

The chemical bonds of polymer materials have different sensitivities to different wavelengths of light in sunlight, which generally correspond to a threshold. The short-wavelength ultraviolet rays of sunlight are the main cause of the aging of the physical properties of most polymers. For example, the action threshold of C-N (carbon-nitrogen) bond is 393nm. However, long-wavelength UV rays and even visible light can damage some pigments and dyes, causing discoloration or fading.

temperature

The higher the temperature, the faster the chemical reaction. The aging reaction is a photochemical reaction. Temperature does not affect the photoreaction speed in the photochemical reaction, but it affects the subsequent chemical reaction speed. Therefore, the effect of temperature on material aging is often nonlinear.

water

Water will directly participate in the material aging reaction. Relative humidity, dew and rain are the main forms of water in nature. Research shows that outdoor materials will be wet for long periods of time every day (up to 8-12 hours a day on average). Dew is the main cause of outdoor humidity. Dew causes more damage than rain because it remains on the material longer, creating more severe moisture erosion.

How should we avoid the impact of aging on materials during product development?

When developing new products, it is very important to conduct aging tests on raw materials. This is because raw materials serve as the basis for manufacturing products, and their composition, structure and performance often directly affect the quality of the final product. Therefore, by conducting aging tests on raw materials, we can more effectively understand the long-term stability, reliability, and durability of raw materials, so as to more accurately predict and control product service life.

Benefits of aging testing on raw materials:

1. Evaluate material stability: The performance and stability of raw materials must be guaranteed throughout the product's service life. Through aging testing, the stability of raw materials during long-term use can be evaluated, and the changes in materials under different use environments and stress conditions can be understood.

2. Simulate actual use conditions: The aging test can simulate various environmental and stress conditions that the product may encounter during actual use. For example, high temperature, humidity, ultraviolet radiation, etc. may cause aging or damage to materials. By aging testing materials that simulate these actual use conditions, you can better predict how the material will perform and last in your product.

UTSTESTER aging test chamber is widely used in various industries, such as textile and leather, electronics, automobiles, aerospace, building materials, etc.

Its main advantages are:

Low cost: The xenon lamp test chamber is the lowest operating cost aging test chamber in the industry. Its low purchase cost, lamp price and operating cost are second to none in the lightfastness testing industry. Xenon weathering and lightfastness testing is now affordable for even the smallest laboratories.

Easy to operate: The test chamber is very easy to install, set up and operate. Specially designed sample holders make sample fixing and evaluation very simple. All models of equipment are fully automatic and can operate continuously 24 hours a day, 7 days a week without supervision. If there is a problem during the test, the device will intelligently prompt an alarm.

Easy to maintain: We believe that technical products do not have to be difficult for customers to understand, maintain, or repair. Our products are extremely simple, avoiding unnecessary functions in experimental design, and strive to make the products convenient and easy to use. The modular subsystem not only facilitates fault diagnosis, but also facilitates replacement of spare parts. These features make maintenance extremely simple, and in most cases do not require the participation of manufacturer maintenance personnel (if necessary, UTSTESTER provides door-to-door service).
