Structure Design and Use Tutorial of Ozone Aging Test Chamber

The ozone aging test chamber is suitable for aging cracking tests of non-metallic materials and rubber products. By stimulating and strengthening the ozone conditions in the atmosphere, the ozone action rules on rubber are studied, the ozone aging resistance and the ozone protection efficiency of rubber are identified and evaluated, and effective anti-aging measures are adopted to improve the service life of rubber products.

Structural design of ozone aging test chamber

1. Set a transparent window at the reasonable position of the box door to observe the changes in indoor samples. The observation window adopts multi-layer hollow toughened glass and inner glued sheet conductive film, which is transparent and heats insulated and is not easy to produce steam frosting.

2. The ozone aging test chamber is stirred by a long shaft fan motor, high and low temperature resistant stainless steel multi-wing impeller to achieve a strong convection vertical diffusion cycle, to make the laboratory temperature uniform and stable all the time.

3. The ozone aging test chamber adopts a nonreaction door handle, which is more convenient to operate.

4. A high-quality fixed Pu movable wheel is installed at the bottom of the ozone aging test chamber, which can facilitate the machine to move to the position. After the caster is fixed with the working principle of refrigeration, the refrigeration cycle adopts the inverse Karo cycle, which is composed of two isothermal processes and two adiabatic processes.

Operating procedures for ozone aging test chamber

1. Install the power supply, connect the power supply correctly, ensure that the ozone aging test chamber is effectively grounded, control the circuit separately, and do not interfere with other equipment.

2. It is recommended to use purified water or distilled water for equipment water addition tests.

3. Sample and place the sample in the ozone aging test chamber, fix it on the sample rack, fix it on the sample rack, and then close the door of the sample chamber.

4. According to the product test requirements, the ozone aging test chamber is set with the corresponding temperature, humidity, ozone concentration, test time, etc.

• Time setting: before the equipment power is turned on, set the time unit and time by dialing the code according to the time setting required by the test, and then turn on the power to set the ozone concentration, temperature, and humidity.

• Ozone concentration setting: adjust the SV (target value) setting and then press the set key to confirm the setting.

• Temperature and humidity setting: please refer to the attached manual.

5. The ozone aging test chamber must maintain a sufficient water source during operation. During the operation of the equipment, the number and time of opening the box door shall be reduced to prevent the sensor probe from being damaged in the laboratory.

6. When the professionally trained personnel no longer use the ozone aging test chamber to operate the equipment for a long time, please conduct deep cleaning.

7. Alarm handling: water shortage alarm, check whether there is a water shortage in the ozone aging test box, whether there is an overtemperature alarm of the humidifier, and whether there is a water shortage in the humidifier. Maintenance: according to the length of the test cycle, regularly clean the sundries in the test box, keep the wet ball gauze clean and replaced, maintain the accuracy and accuracy of humidity measurement, clean the rust and impurities in the water storage tank and avoid pipe blockage. There is a normally open-drain port at the back of the ozone aging test chamber. The two normally closed drain ports generated in the discharge chamber during the test are opened during regular maintenance.
