Overview

The small capacity UV aging chamber CNHS-150-UV has a built-in spray system and uses fluorescent UV lamps that can best simulate the UV spectrum in sunlight. It is combined with temperature control, humidity supply, and other devices to simulate the discoloration, brightness, and intensity reduction of materials; Factors such as cracking, peeling, powdering, oxidation, etc. caused by sunlight (UV range), high temperature, high humidity, condensation, dark cycles, etc

Instructions for using the UV aging test chamber:

1、 Preparation before the experiment

Confirm that the equipment power supply is AC220V/50Hz and the grounding is reliable. Check that the UV lamp is not damaged or stained, and that the water level in the condensation/spray water tank is normal and deionized water is used. Cut the samples according to standards such as GB/T 16422.3, ensuring that the surface is clean and free of scratches. After numbering and marking, face the lamp tube and fix them evenly on the sample holder. Leave enough gap between the samples to avoid obstruction, and install a blackboard thermometer to monitor the temperature.

2、 Parameter setting and startup

Connect the main power supply and enter the settings interface after the system self-test shows no alarms: select UVA-340 or UVB-313 lamp and set the irradiance (0.35-0.85W/m ² @ 340nm); Set the temperature during the illumination stage to 50-70 ℃, the condensation stage to 40-60 ℃, and the humidity to ≥ 95% RH; set the illumination/condensation duration (typical 8h illumination+4h condensation) and the total test duration, and enable data recording and alarm functions. Close the box door and lock it, press the run button, and the equipment will preheat for 30 minutes before officially timing.

3、 Experimental monitoring and closure

Inspect every 2-4 hours during operation, monitor the status inside the box through the observation window, record parameters such as irradiance, temperature and humidity, and strictly prohibit opening the door when the lamp is on. After the experiment is completed, turn off the UV lamp and heating first, wait for the temperature inside the box to drop to room temperature before opening the door, and wear gloves to take out the sample. Clean the inner wall of the box, sample holder, and water tank, replace the water in the water tank, open the box door to dry, turn off the main power, and organize data to form a report.

Small capacity UV aging box CNHS-150-UV with built-in sprayMain features:

1. The inside and outside of the box are made of 304 stainless steel, and the sample holder is made of stainless steel or aluminum alloy.

2. Adopting a touch screen controller, programmable modes such as temperature, lighting, rain, condensation, etc

3. The box is equipped with a fluorescent UV lamp with UV spectrum, and the surface of the test sample is parallel to the plane of the UV lamp. The UV light and condensation time can be alternately adjusted

4. The door opening method is a one-way stretching type, which can be easily closed without taking up space.

5. The air duct adopts a single circulation system with an imported axial flow fan, which improves the air flow brightness and heating capacity, and significantly improves the temperature uniformity inside the test chamber.

6. The inner tank is heated by a sink, with fast heating and uniform temperature distribution. The inner tank water level automatically replenishes to prevent damage to the heating tube due to empty burning. The U-shaped sedimentation device has a drainage system.

7. Built in sprinkler system, automatic nozzle, adjustable water pressure.

8. The bottom is equipped with movable wheels for easy movement of the laboratory position.

9. Multiple safety protection functions such as overheating, water shortage, and power overload.
