Photoaging reliability testing

You'erhongxin has climate and environmental testing equipment such as walk-in temperature and humidity chambers, salt spray chambers, etc., which can be used for tests such as cold and hot shock, gas corrosion, etc., with wide parameter coverage; Mechanical testing includes three comprehensive vibrations, packaging compression resistance, etc., and the maximum load of the equipment700kg, duration of impact0.2-70msWith comprehensive testing capabilities and advanced equipment performance, it can accurately simulate usage and transportation environments, and serve multiple products such as electronic products and automotive parts.

Photoaging reliability testingIt is a testing method to accelerate the aging process of materials or products and evaluate their anti-aging performance and service life by simulating key factors such as light (mainly sunlight), heat and humidity in the natural environment.

Core simulation objects: ultraviolet, visible, and infrared light in sunlight, combined with temperature and humidity cycling.

Test purpose: To predict whether the material will experience aging problems such as discoloration, cracking, and performance degradation in actual use.

Applicable objects: Various materials or products exposed to light environment, such as plastics, coatings, textiles, rubber, electronic components, etc.

Photoaging reliability testingThe main types

Xenon lamp aging test: Simulate full spectrum sunlight, including ultraviolet, visible, and infrared light, close to natural aging, suitable for most materials.

UV aging test: only simulates the UV band in sunlight, with obvious accelerated aging effect, commonly used in plastics, coatings, etc.

Carbon arc lamp aging test: commonly used in the early days, with spectral differences from natural light, currently mostly used in specific industry standard scenarios.

Selection method for photoaging testing

Matching environmental scenarios: Xenon lamps (full spectrum) are selected for outdoor use, and UV aging is optional for indoor enclosed environments.

Combining material types: Plastic and rubber are preferred for UV or xenon lamps, while textiles and coatings are recommended for xenon lamps (more closely related to actual use).

Follow industry standards: according to the corresponding national and American standards of the product (such asASTM）Or European standards require the selection of testing types.

The core content of photoaging testing

Appearance changes: Detect surface issues such as discoloration, loss of gloss, cracking, powdering, and bubbling of materials.

Physical properties: Test the degree of attenuation of indicators such as tensile strength, elongation at break, and hardness.

Chemical properties: Analyze whether materials undergo chemical changes such as degradation, oxidation, cross-linking, etc.
