Usage :     Though the amount of ozone in the atmosphere is very little, it is, howeber the major element for causing cracks in rubber. The machine produced by our company ofrtesting ozone-resisiting ageing can be used in man-made simulation or for strengthening the ozone condition in the atmosphere to make study on the law of the role of ozone on rubber and quickly verify and appraise the character of ozone-resisiting ageing of rubber and the protective effect of ozone agent.     TECHNICAL INDEXES :     1.
