Application of ozone aging test machine

In today's material science and industrial production fields, the durability and stability of products are crucial. As a key testing equipment, the ozone aging tester plays an indispensable role.

1. Quality control of rubber products

Rubber is widely used in many fields such as tires, seals, conveyor belts, etc. For tires, during long-term driving, they are constantly exposed to the atmospheric environment containing ozone, especially in industrial pollution areas or high-altitude areas with strong ultraviolet rays. Ozone can easily cause cracks on the rubber surface, seriously affecting the safety and service life of the tires. Through the ozone aging tester, different concentrations of ozone (such as 20-50 ppm in urban road environments, 50-100 ppm around industrial plants), temperature (from minus 20°C in cold areas to more than 40°C in tropical areas) and humidity conditions are simulated to accurately test the anti-aging performance of rubber tires, helping tire manufacturers to select high-quality formulas, ensure that the products can adapt to complex and changeable actual road conditions, and reduce safety risks such as tire blowouts. This is especially true for seals, such as the rubber sealing ring in the engine compartment of a car. Once a gap appears due to ozone aging, it will cause serious problems such as oil leakage. Using a testing machine for early detection can provide a solid guarantee for the quality of the seals.

2. Optimization of plastic product performance

Plastic products can be found everywhere in outdoor buildings, agricultural facilities, and daily necessities. Building exterior materials such as plastic window frames and awnings are exposed to wind, sun, and rain for a long time. The ozone in them will corrode the surface of the plastic, making it brittle, faded, and lose its luster. With the help of an ozone aging tester, by setting parameters that match the local climate characteristics, researchers can observe the changes in the mechanical properties of plastics after accelerated aging, such as tensile strength attenuation and impact toughness reduction, and then improve the plastic formula, add antioxidants, UV absorbers and other additives, enhance the weather resistance of plastic products, extend their outdoor service life, and reduce the waste of resources and cost expenditures caused by frequent replacement.

3. Aerospace material screening

In the field of aerospace, materials face extremely harsh environments. The ozone layer is thin but the ultraviolet rays are strong in the high altitude. The synergistic effect of ozone and radiation is extremely harmful to the aircraft shell, sealing materials, etc. The ozone aging tester can simulate the ozone environment under low pressure and strong radiation at high altitude, and test candidate materials with harsh test conditions far exceeding those on the ground. Only those materials that show excellent resistance to ozone aging in the test and can maintain structural integrity and sealing reliability are eligible to be selected to ensure the long-term stable operation of aerospace vehicles and the smooth implementation of space exploration missions.

4. Driving force of scientific research and innovation

Scientific research institutions use ozone aging testers to deeply explore the aging mechanism of materials. By finely adjusting the test parameters and observing the evolution of the microstructure of different materials under the action of ozone, from the whole process of molecular chain breakage, cross-linking to macroscopic performance degradation, it provides theoretical support for the development of new anti-aging materials, promotes the development of the entire field of materials science, and breeds more high-performance and long-life innovative materials to meet the ever-increasing needs of industry and life.

In short, the wide application of ozone aging testers in many industries is continuously helping to improve product quality and technological breakthroughs, laying a solid foundation for the steady development of modern society.
