The plastic pipe industry UV weathering test chamber is a specialized device used to simulate comprehensive climatic conditions such as ultraviolet light, temperature, and humidity in natural environments to conduct accelerated aging tests on materials like plastic pipes. It aims to evaluate the weather resistance and lifespan of materials during long-term outdoor use.

Core Functions and Features

Simulating Natural Climate

UV Simulation: Utilizes special imported UV lamps (such as UVA-340 or UVB-313) to simulate ultraviolet radiation from sunlight and accelerate material aging.

Condensation and Spray System: Simulates nighttime dew through condensation and rainwater through spraying, realistically replicating outdoor humid environments.

Temperature and Humidity Control: Temperature range typically from RT+10°C to 70°C, humidity ≥90% RH, supporting cyclic tests of light exposure, condensation, and rain spray.

Testing Effects

Accelerates the detection of aging phenomena such as fading, discoloration, loss of gloss, chalking, cracking, peeling, embrittlement, and reduced strength in materials.

Significantly shortens testing time, simulating months or even years of outdoor aging effects within days or weeks.

Equipment Structure

Chamber Material: Made of stainless steel (SUS), corrosion-resistant and long-lasting.

Lamp Configuration: Equipped with multiple UV lamps (e.g., 8 lamps), supporting UV-A or UV-B wavelength switching.

Sample Holder: Made of stainless steel or aluminum alloy, adjustable for specimen installation thickness, and supports custom non-standard designs.

Safety Design: Dual-direction hinged chamber lid, automatic lamp power cutoff when opened; multiple safety mechanisms including over-temperature protection and low water level alarm.

Example Technical Parameters (Taking AP-UV3-FB as an Example)

Temperature Range: 60-70°C during light exposure phase, 50-55°C during condensation phase.

Humidity Range: Relative humidity >95% during condensation phase.

Irradiance Intensity: 0.55 W/m2·nm at 340nm (UVA-340 lamp).

Test Time: Adjustable from 0-999 hours, supports timed automatic start/stop.

Sample Dimensions: Standard specimens 75×150mm or 75×300mm (customizable).

Power Requirements: 230V/50Hz, power approx. 1800W (max).

Equipment Dimensions: Working chamber size 1170×450×500mm, overall dimensions 1300×550×1380mm.

Application Areas

Plastic Pipe Industry

Evaluates the anti-aging performance of pipes (e.g., PE, PVC, PP) after long-term outdoor exposure, optimizing material formulations (e.g., adding carbon black UV inhibitors).

Tests surface discoloration, chalking, and changes in impact strength of pipes to ensure compliance with industry standards (e.g., ASTM G154, GB/T 14522).

Other Related Industries

Coatings and Inks: Tests lightfastness and color retention of architectural exterior coatings and automotive topcoats.

Automotive Manufacturing: Evaluates weather resistance of car paints, plastic parts, and rubber seals.

Electronics and Appliances: Assesses UV resistance of products like phone cases and computer housings.

Textile Printing and Dyeing: Simulates the effects of sunlight exposure on color fastness of textiles.

Selection Recommendations

Brand and Certification

Choose reputable brands (e.g., Aipu Technology/A-PKJ) to ensure equipment complies with domestic and international standards (e.g., GB/T, ISO, ASTM).

Prioritize equipment with metrology certification and calibration certificates to ensure test data accuracy.

Functional Requirements

Select the light source based on the type of material being tested (UVA-340 simulates natural sunlight, UVB-313 accelerates aging).

Confirm whether the equipment supports spray functionality (simulating rainwater impact) and condensation cycles (simulating dew).
