Xenon Weathering Chamber with Multi-Channel Data Acquisition System

Xenon Lamp Aging Tester Integrated Multi-Channel Data Acquisition System: Intelligent Innovation for Material Weathering Tests

A technological breakthrough: real-time capture of full-dimensional data

16-channel synchronized acquisition:

Environmental parameters: irradiance (340/420nm band), black panel temperature (0~120℃±0.5℃), humidity (10%~98% RH±2%).

Material Response: surface deformation (laser displacement sensor, accuracy ±0.01mm), mechanical stress (strain gauge, range 0~500N), chemical degradation (integrated fiber optic probe, supports real-time analysis of FTIR spectra).

Dynamic coupling control:

Spraying system linked with temperature and humidity to simulate tropical rainstorm (40℃/95% RH + 18 minutes spraying), synchronous recording of coating expansion rate and adhesion changes.

Photo-thermal-mechanical synergistic loading (e.g. UV illumination + 80℃ + cyclic pressure), reproducing the compound aging scene of automobile tires at high speed.

Application Scenario: Full-cycle Empowerment from R&D to Failure Analysis

1. High-voltage wiring harness for new energy vehicles

Corona aging monitoring: Collect partial discharge (pC level) and silicone rubber sheath surface crack data, establish electric-thermal-mechanical coupling life model, and screen corona-resistant formulations.

Case: a manufacturer through multi-channel testing, found that 125 ℃ + 0.8 W / m ² @ 340nm conditions, adding 3% alumina silicone rubber life increased by 2.3 times.

2. Aerospace sealing materials

Extreme environment simulation: -40℃ (cryostat extension module) to 150℃ cycle, synchronously monitor the compression resilience and leakage of Viton seals to meet the MIL-STD-810H standard.

3. PV backsheet weatherability optimization

Energy analysis by wavelength: real-time monitoring of UV (295~385nm), visible light and infrared (700~2500nm) energy ratio to locate the main cause of yellowing of EVA film (cross-linking fracture triggered by UV light at 315nm).

Core Advantages: Accurate, Efficient and Traceable

1. Multiply the testing efficiency

Intelligent acceleration algorithm: dynamically adjust temperature and humidity based on Arrhenius model, 21 days equivalent to 5 years of natural aging (traditional methods only 3 years).

Parallel testing: 32 groups of samples are independently controlled, supporting synchronized testing of rubber, plastic and coating, shortening the R&D cycle by 50%.

2. Data deep mining

AI early warning system: real-time analysis of data trends, 48 hours in advance warning of xenon lamp light failure (>5%), sensor drift and other anomalies.

3D heat map generation: visualize the differentiated aging degree of instrument panel, seat, and door panel areas in automotive interior material testing.

3. Global Compliance Assurance

Standard coverage: ISO 20509:2025 (multi-factor accelerated aging), IEC 60068-2-5 (humidity-heat cycle), GB/T 2423.24 (light aging).

Certification support: Test reports go straight to UL, TÜV, CATARC and other certification organizations to reduce the cost of repeated tests.

How do test reports for multi-channel systems meet international certification requirements?

Data integrity: the report automatically includes raw data (sampling rate 1Hz), environmental parameter curves, and equipment calibration certificates (ISO 17025 recognized).

Standards coverage: Built-in templates support 50+ standards such as ISO 4892-3 (plastics/rubber), IEC 61215 (photovoltaic), SAE J2527 (automotive), etc., generating compliance reports with one click.

Third-party recognition: TÜV, SGS and other organizations recognize device data, shortening the certification cycle by 30% (no need to repeat tests).

How to optimize material formulation using multi-channel data? Give an example.

Take automotive tire rubber as an example:

Data correlation: Simultaneous monitoring of 340nm UV intensity (0.55 W/m²) and the rate of decrease in tear strength of the rubber material revealed that for every 10% increase in UV dosage, the loss of strength accelerated by 15%.

Formulation adjustment: Addition of 2% zinc oxide nanoparticles (UV absorber) reduced the rate of strength loss to 8% after retesting.

Validation cycle: compressed from 6 months to 45 days in the traditional trial-and-error method, saving 40% in R&D costs.
