Ozone aging chamber manufacturerIt is mainly suitable for testing the ozone aging resistance of polymer materials and their products. The content of ozone in the atmosphere is the main factor affecting the aging of polymer materials and their products. The ozone aging chamber can simulate and enhance the ozone conditions in the atmosphere, obtain test results that are similar to actual use or reproduction in a short period of time, study the effect of ozone on polymer materials and their products (rubber), quickly identify and evaluate the anti ozone aging performance of rubber and the protective effect of anti ozone agents, and then take effective anti-aging measures to improve the service life of rubber products.

There are two methods for ozone aging test in ozone aging chamber: one is static strain test method, and the other is dynamic strain test method. The ozone aging chamber consists of three main parts: control system, ozone generation system, sample aging chamber, and ozone measurement. Ozone generator system: mainly includes components such as ozone generator, air purification device, heat exchanger, and airflow control system. The ozone generator uses high-voltage silent discharge tubes, which can obtain higher concentrations of ozone. The sample aging chamber is enclosed and unlit (except for intermittent lighting). A window is opened on the door of the test box to observe the surface of the sample. The outer shell of the test box is made of cold-rolled steel plate electrostatically sprayed, which has a beautiful and elegant appearance; The inner walls of the chamber, conduits, sample fixtures, and structural materials are made of stainless steel that is not easily decomposed by ozone or corrosion-resistant inert materials. In addition, the equipment is equipped with a timing device and an intelligent digital display controller for measuring and regulating ozone concentration. It can directly set the ozone concentration value and implement PID self-adjusting control, with high control accuracy and simple and convenient operation.
