Abstract: As core equipment for material weatherability testing, the Xenon Lamp Accelerated Aging Chamber adopts “natural environment simulation + accelerated aging” as its core design principle. Through the cooperation of full-spectrum xenon arc lamps and multi-environment control modules, it accurately simulates and accelerates the natural outdoor aging process of materials. Taking the LISUN XD-WAT-Ci3000 Xenon Lamp Accelerated Aging Chamber as the research object, this paper analyzes its technical principle, core structure and performance parameters in detail, expounds its application value in material R&D, industrial product quality inspection and other fields, and provides a reference for related industries to select weatherability test equipment.

1. Introduction

When materials are used outdoors, long-term exposure to natural factors such as sunlight radiation, temperature changes, humidity and rain will cause aging phenomena such as fading, chalking, cracking and mechanical performance degradation, which directly affect the service life and safety of products. Traditional natural exposure tests take months or even years to obtain aging data, which can hardly meet the efficient testing requirements of modern material R&D and industrial production.

As key equipment for artificial accelerated aging testing, the Xenon Lamp Accelerated Aging Chamber can compress the natural aging process of materials into days or weeks by simulating the core aging factors in the natural environment, making it an important means for material weatherability research and quality inspection. As a typical water-cooled Xenon Lamp Accelerated Aging Chamber, the LISUN XD-WAT-Ci3000 is widely used in many industries due to its high-simulation environment simulation capability and precise parameter control performance. Its technical design and application characteristics are of typical research value.

2. Core Technical Principle of the Xenon Lamp Accelerated Aging Chamber

The core design logic of the Xenon Lamp Accelerated Aging Chamber is “simulating nature + accelerating aging”. Taking LISUN XD-WAT-Ci3000 as an example, through the cooperation of the light source system and environment control system, it completely simulates the three core factors causing material aging: sunlight, temperature and humidity, and achieves the goal of accelerated testing by strengthening aging conditions.

2.1 Natural Sunlight Restoration with Full-Spectrum Xenon Arc Lamp

The light source is the core component of the Xenon Lamp Accelerated Aging Chamber. The xenon arc lamp equipped in LISUN XD-WAT-Ci3000 can reproduce the full spectrum of sunlight, with a spectrum similarity of more than 90% to natural light. It can accurately restore the ultraviolet and visible light bands in outdoor sunlight that damage materials.

Unlike traditional UV lamps that can only simulate a single UV band, the full-spectrum radiation of the xenon arc lamp is more consistent with the irradiation characteristics of natural sunlight, avoiding large deviations between test results and actual natural aging caused by a single light source spectrum. The xenon lamp power of this equipment is 4500W with a service life of up to 2000 hours. The irradiance can be directly set and controlled, up to 2 suns. By increasing the irradiance intensity, the accelerated aging of sunlight radiation is realized. Meanwhile, the measurement accuracy of the irradiance probe is ±5% and the repeatability is ±1%, ensuring precise control of light intensity and reliability of test data.

2.2 Comprehensive Environment Simulation with Multi-Module Cooperation

LISUN XD-WAT-Ci3000 Xenon Lamp Accelerated Aging Chamber integrates three core modules: temperature control, spraying and humidity adjustment, constructing an alternating cycle environment of “light – high temperature – spraying – low temperature condensation” to realize all-round simulation of natural climate.

The temperature system can directly control the chamber temperature, black panel/black standard temperature, with a temperature range from room temperature to 85℃ and control accuracy of ±2℃. Smart Damper technology accurately compensates for changes in the laboratory environment to ensure stable test temperature. The humidity system adopts VibraSonic humidification technology, with a humidity control range of 20%~95%RH and accuracy of ±3%RH, which can simulate natural environments with different humidity.

The spraying system can achieve uniform spraying on the front and back of samples, with adjustable water spray pressure of 0.12~0.15Mpa and nozzle aperture of 0.8mm, accurately simulating the scouring effect of natural rainfall on materials. At the same time, it can cooperate with the low-temperature module to realize condensation environment simulation, restoring the condensation aging condition of materials under outdoor day-night temperature differences. The cooperative work of the three environmental modules enables the equipment to simulate the natural environments of tropical, subtropical, temperate and other climate regions, meeting the weatherability test requirements of different materials.
