Double Spray System Xenon Lamp Aging Box: Core Technology Analysis

SPECIFICATION

Double spray system xenon lamp aging box: core technology analysis

1. Core design concept

Double spray system xenon lamp aging chamber is designed to accelerate the aging process of materials in complex climatic conditions through a high degree of simulation of the environmental simulation. Its design integrates three core modules of light simulation, dynamic spraying and precise temperature control, in order to reproduce the real environment of materials exposed outdoors for a long period of time, such as sunshine, rain, day and night temperature difference, and so on.

2. Key technology components

Xenon lamp light source

Adopting full-spectrum xenon arc lamps, covering ultraviolet (280-400nm), visible light and infrared wavelengths, accurately simulating solar radiation. The intensity of the light source supports multi-level adjustment (e.g. 0.5~1.2 W/m²@340nm) to meet the testing requirements of different standards (ISO 4892, ASTM G155).

Dual Shower Mechanism

Differing from the single shower system, the dual shower design simulates more realistically the wetting and flushing of natural rainfall through the dual action of top spray + side water mist. Spray parameters (e.g. frequency, water pressure, water temperature) can be independently programmed to support intermittent or continuous spraying modes to suit different test scenarios.

Intelligent environment control

Temperature control range: -20℃~80℃ (optional expansion to 100℃)

Humidity control: 10%~98% RH (non-condensing)

Support customized temperature and humidity curves to simulate day/night cycle or extreme climate.

3. Core application values

Accelerated aging assessment: Condense several years of natural aging into hundreds of hours of experiments to quickly verify material life.

Failure analysis: pinpoint material aging weaknesses (e.g., coating cracking, plastic yellowing, rubber hardening).

Quality control: Provide standardized weathering test basis for automotive, construction, new energy and other industries.

4. Industry Application Scenarios

New energy vehicles: testing the UV aging resistance of battery shells and the rain and corrosion resistance of charging pile materials.

Outdoor building materials: evaluate the color change of exterior wall coating, and the temperature fatigue resistance of glass curtain wall.

Consumer electronics: verify the light yellowing resistance of cell phone shells and the waterproof durability of rubber seals.

Photovoltaic module: simulate 25 years of outdoor irradiation, test the decay of light transmission rate of EVA film.

5. Comparison of technical advantages

6. Operation optimization recommendations

Specimen pre-treatment: avoid direct testing of materials with surface contamination, it is recommended to clean or standardized curing.
