The changes in ozone concentration, temperature and humidity at any point in the working space of the ozone aging test chamber reach the characteristics of the equipment itself. The status of the performance indicator when requested. Under the steady state of the ozone aging test chamber, the average value of the ozone concentration display value is the same as the actual measurement of all measurement points in the work space. The difference between the average ozone concentration. Under the steady state of the ozone aging test chamber, within a specified time interval, the ozone concentration at any point in the working space changes with the The amount of change in time. Under the steady state of the ozone aging test chamber, the average value of the ozone concentration at any two test points in the working space is difference. 3.6 load Samples tested using an ozone aging test chamber.

4 Overview

The ozone aging test chamber is mainly used to simulate and strengthen ozone conditions in the atmosphere, and to study the effect of ozone on rubber, plastic and other materials. It is an equipment that can quickly identify and evaluate the anti-ozone aging performance of materials based on the law of action. It is mainly controlled by the ozone concentration system system, temperature and humidity control system and work space. Ozone concentration control systems generally use high-voltage discharge or ultraviolet irradiation
