How to adjust the ozone concentration of the ozone aging test chamber
The ozone aging test box is divided into high concentration and low concentration. How should its ozone concentration be adjusted?
When an ultraviolet lamp is used, the ozone concentration can be controlled by adjusting the voltage applied to the lamp tube, the gas flow rate, or the method of covering part of the lamp tube. When a silent discharge tube is used, the ozone concentration can be controlled by adjusting the voltage applied to the generator, electrode size, oxygen flow rate, or air flow rate. These adjustment methods should keep the ozone concentration within the tolerance range of the specified concentration. In addition, after opening the test box to put or inspect the sample, the ozone concentration should be able to return to the concentration specified in the test within 30 minutes. The ozone concentration in the test chamber shall not exceed the concentration specified in the test under any circumstances.
Ozone aging test box can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheath and other products, under static tensile deformation, exposed to air with constant ozone concentration and constant temperature test box under static tensile deformation, as scheduled Time to test the sample, from the degree of cracks or other changes in the surface of the sample, to evaluate the ozone aging resistance of the rubber.
