Overview
The AISRY ASR-CY-150L ozone aging test chamber is a test device used to simulate and strengthen ozone conditions in the atmosphere to study the effect of ozone on rubber. It can quickly identify and evaluate the anti-ozone aging performance of rubber and the protective efficacy of anti-ozone agents. It is suitable for both static and dynamic tensile test methods.
Features
1. It adopts an all-in-one machine structure, the inner box and the outer box are made of SUS304 stainless steel plate or paint, and the thermal insulation layer is double protected by rigid polyurethane foam and aluminum silicate thermal insulation cotton.
2. The box door is equipped with observation window, lighting and anti-condensation electric heating device, and two silicone rubber sealing strips ensure sealing.
3. Standard static test fixture, optional dynamic experimental sample holder, the fixture is made of materials that are not easy to analyze ozone (such as aluminum), the sample holder can be swirled/spun 360 degrees, and the speed can be adjusted.
4. Adopt fin-type heat dissipation tubular stainless steel electric heater for heating, and cooperate with ID adjustment and solid state relay for precise temperature control.
5. Equipped with a mechanical refrigeration/air-cooled refrigeration system, using environmentally friendly refrigerant R404, and using nitrogen shielded welding and other processes to ensure that the system is clean and reliable.
6. The ozone system uses voltage silent discharge tubes to generate ozone, and is equipped with High Accuracy Ozone Sensor and Glass Flow Rotor Meter for precise concentration control and adjustment. After the experiment, the ozone can be discharged to the outside through a special exhaust system.
7. Adopt 7-inch color LCD touch man-machine interface controller, support Chinese and English switching, with program editing, Linear dispersion display, historical data, reservation start and stop and other functions.
8. With multiple safety protection devices, including Compressor overheating/high voltage/overcurrent protection, heater overtemperature protection, cycle motor overheating protection, high temperature/low temperature/overtemperature protection, reverse phase underphase protection and smoke alarm power-off protection.
Principle
This device generates ozone through an ozone generator (using a voltage silent discharge tube) and introduces it into the test chamber to simulate the ozone environment in the atmosphere. The test is divided into two methods: static test is to put the pre-stretched sample into the box for testing; dynamic test is to install the sample on the fixture in the box and stretch it during the test (the tensile range is 5% -45% of the sample itself). The device precisely controls the ozone concentration, temperature and airflow speed in the box through High Accuracy Ozone Sensor and controller to strengthen the aging effect of ozone on rubber samples, so as to quickly evaluate its anti-ozone performance.
Applications
Rubber anti-ozone aging performance research, cable insulation and sheath material ozone resistance test, anti-ozone agent protective efficacy evaluation
Standards
GB/T7762-2003、GB/T2951.21-2008、GB/T 11206-2009
Steps
Specimen preparation: according to the provisions of GB/T 9865.1, cut the sample from the new molded test piece or finished product, the width of the long standard sample is not less than 10mm, the film thickness is 2.0mm +/- 0.2mm, and the length between the clamps before stretching is not less than 40mm.
2. Sample installation: For static testing, fix the stretched sample on the fixture and place it in the box; for dynamic testing, install the sample on the fixture of the dynamic sample holder and set the required tensile range.
3. Parameter settings: Set test temperature, ozone concentration, test time, cycle times and other parameters through the touch controller.
4. Start operation: After confirming the parameters, start the equipment, and the ozone generator, temperature control system, circulating fan, etc. start working.
5. Process monitoring: Monitor the test process and Linear dispersion through the observation window and controller screen.
6. End of the test: After reaching the set time, the equipment stops running. Start the ozone exhaust system to discharge the ozone in the box to the outside.
7. Take out the sample: After the exhaust is completed, open the box door and take out the sample for subsequent performance evaluation.
Notice
* The equipment should be installed in a well-ventilated place without direct light and away from heat sources.
* Before use, please confirm that the Power supply voltage meets the requirements (AC220V +/- 5%/50Hz +/- 0.5Hz) and ensure reliable grounding.
* Dynamic specimen holder is optional, please confirm the configuration if you need to perform dynamic test.
* Specimen clamps should be made of materials that are difficult to analyze ozone, such as aluminum.
* During the test, do not open the door frequently, so as not to affect the ozone concentration and temperature Stability.
After the experiment, the ozone in the box must be completely discharged to the outside through a dedicated exhaust system before the door can be opened to ensure the safety of personnel.
* Regularly check the ozone generator, Sensor, sealing strip and other components to ensure their normal operation.
The equipment has multiple safety protection functions. If an alarm occurs, please check the fault according to the controller prompt information, or contact a professional to deal with it.
* For maintenance, please refer to the attached maintenance manual and controller manual.
