Ozone aging test box

Abstract

The invention relates to the technical field of environmental testing instruments and in particular relates to an ozone aging test box. The ozone aging test box comprises a box body, an electrical cabinet, a refrigerating system, an ozone generating system, an ozone detection system and an electrical system, wherein a box door is arranged on the front side of the box body; an observation window is formed in the box door; an ozone chamber is formed inside the box body; an ozone rack is arranged in the ozone chamber; the ozone detection system comprises an evaporator, a gas-liquid separator and an ozone sensor; the ozone sensor is arranged outside the ozone chamber; one end of the evaporator is connected with an exhaust hole of the ozone chamber through a pipeline; the other end of the evaporator is connected with an air inlet of the gas-liquid separator through a pipeline; an air outlet of the gas-liquid separator is connected with the ozone sensor through a pipeline; the ozone sensor is connected with the electrical system through a circuit. Compared with the prior art, the ozone aging test box has the advantages that the ozone sensor is convenient to mount and maintain, the test box is not influenced by temperature and humidity in a workroom, the service life is long, the accuracy of detection concentration of the ozone sensor is guaranteed, and the degree of automation is high.

Description

[technical field] [0001] The invention relates to the technical field of environmental test instruments, in particular to an ozone aging test chamber. [Background technique] [0002] The content of ozone in the atmosphere is very small, but it is the main factor for rubber cracks. The ozone aging test chamber can simulate and strengthen the ozone conditions in the atmosphere due to its very high concentration of ozone gas, so that it can quickly detect rubber materials in high concentrations. In the case of ozone gas, it is a method to test the ozone cracking resistance of rubber products, quickly identify and evaluate the anti-ozone aging performance of rubber and the protective effect of anti-ozonants, and then take effective anti-aging measures to improve the service life of rubber products. However, the ozone aging test chambers currently on the market mainly have the following problems: [0003] (1) Since most of the sensors for detecting the concentration of ozone gas...

AI Technical Summary

Problems solved by technology

[0003] (1) Since most of the sensors for detecting the concentration of ozone gas are electrochemical, it is easy to enter water vapor under the test conditions with humidity, resulting in the sensor not working or the detection concentration being inaccurate;

[0004] (2) The manufacturing cost of the sensor adopting the ultraviolet absorption method is too high;

[0005] (3) The installation and maintenance of the ozone gas concentration sensor is very inconvenient;

[0006] (4) The degree of automation is not high, centralized operation cannot be performed, and the storage of historical test data is not ideal
