Product Information:

The Si80 domestic carbon arc aging chamber is a comprehensive climate testing device mainly used to simulate the changes in materials exposed to sunlight under different environmental conditions. It uses a carbon arc lamp that can simulate the spectrum of sunlight to measure the light resistance of materials. It is suitable for the selection of new materials for various materials such as plastics, rubber, paints, coatings, textiles, as well as the evaluation of durability after existing material improvements or changes in material composition.

Product Features

Precision Irradiation Control: Equipped with irradiance sensors and a closed-loop control system, it automatically compensates for energy attenuation caused by lamp aging, ensuring experimental consistency.

Authentic Dew Simulation: A unique condensation system generates water vapor through a heated water bath, forming uniform dew droplets on sample surfaces to perfectly replicate outdoor humid environments.

Intelligent Operation: The touchscreen controller supports multiple preset programs, enabling cyclic switching between “Lighting,” “Condensation,” and “Spraying” modes.

Sturdy and Durable Construction: The chamber utilizes corrosion-resistant premium stainless steel material. The sample rack design ensures uniform illumination and facilitates easy loading/unloading.

Multi-Layer Safety Protection: Features include low-water level alarm, over-temperature power cutoff, and sensor failure alerts, guaranteeing 24/7 operational safety in laboratories.

Test Procedures

Sample Loading: Secure specimens to the sample holder. Fill any empty spaces with spacers to maintain chamber pressure.

Lamp Verification: Install corresponding UVA or UVB lamps according to test standards and record lamp operating time.

Cycle Setup: Configure light intensity, temperature, and condensation/spray cycle duration in the controller.

Test Initiation: Verify water supply system, start equipment, and allow instrument to enter automatic cycle testing mode.

Process Monitoring: Periodically review irradiance readings and operational curves on the touchscreen to ensure data remains within tolerance limits.

Result Evaluation: Remove samples after testing concludes. Assess aging degree via visual comparison, color difference measurement, or physical strength testing.

Maintenance Information

Lamp Maintenance: Replace lamps sequentially every 1600-2000 operating hours to maintain stable irradiance energy.

Water System Cleaning: Use deionized or distilled water exclusively. Clean the water tank regularly to prevent scale buildup that impairs heating efficiency.

Sensor Calibration: Calibrate the irradiance sensor every six months to ensure internationally valid test data.

Environmental Requirements:

The test chamber should be placed in a well-ventilated laboratory, and the fan filter should be cleaned regularly.
