Overview
QL-225 ozone aging test chamber is a professional test equipment of ZKHS brand, which is suitable for sunlight resistance and artificial Illuminant aging test of Non-metallic materials. The box body is processed by numerical control machine tool, which is beautiful and easy to operate.
Features
1. The box body is processed and formed by numerical control machine tool, and the shape is beautiful and generous. The box cover is the side reverse buckle handle type, which is easy to operate
2. The inner tank of the box is made of imported stainless steel plate, and the shell is sprayed with A3 steel plate. Appearance has good texture and high cleanliness
3. The heating method is electric heating wire heating, which heats up quickly and has a uniform temperature distribution
4. Using PT100 temperature transducer and imported instrument to control heating, good temperature stability
5. The lighting can be independently controlled and alternately cycled, and the control time can be arbitrarily set within 0~ 999H
6. Equipped with 360 degree swirl/spin sample holder, 1 rpm
7. With multiple safety protection functions such as leakage, short circuit, overtemperature, motor overheating, overcurrent, etc
Principle
The equipment is heated by electric heating wire to achieve rapid heating, and the PT100 temperature transducer and imported microcomputer integrated controller are used to precisely control the temperature. The ozone generator uses a silent discharge tube to generate ozone, and the imported concentration analysis regulator monitors and adjusts the ozone concentration in real time. At the same time, the lighting system can be independently or alternately cycled to simulate the aging test process under different environment conditions.
Applications
Testing of Non-metallic Materials for Resistance to Sunlight and Illuminant aging
Standards
GB/T16777-2008、GB/T12967.4-2014
Steps
1. Connect AC380V +/- 10% 50Hz three-phase five-wire power supply
2. Set the required temperature range (RT + 10 ℃~ 70 ℃ or 0 ℃~ 70 ℃)
3. Set humidity range (65%~ 98% R.H or 40%~ 98% R.H)
4. Set the ozone concentration range (low concentration 10~ 1000PPhm or high concentration 1~ 500PPm)
5. Set the lighting control time and alternate control time (0~ 999H)
6. Set the test time (0~ 9999 minutes or hours)
7. Select the specimen state (dynamic or static)
8. Start the equipment and start the test
Notice
• The power of the equipment is 5.5KW, and it is necessary to ensure that the power supply meets the requirements of AC380V +/- 10% 50Hz three-phase five-wire system
• Inner chamber dimensions of 500 * 600 * 750mm, sample size should not exceed this range
• Ozone concentration Fluctuation is +/- 10%, pay attention to concentration stability when testing
• Temperature Fluctuation of +/- 0.5 ℃, Humidity Fluctuation of + 2, -3% R.H
• The gas flow rate range is 12~ 16mm/S, which needs to be kept within the specified range
The equipment has multiple safety protection functions, but it still needs regular inspection and maintenance
• The sample rack rotates at 1rpm to ensure that the sample is tested evenly
