Description

Technical Field

[0001] The invention relates to the technical field of ozone fumigation testing, and in particular to an ozone fumigation testing device. Background Art

[0002] Rubber products will inevitably be corroded by various factors such as ultraviolet rays, oxygen, temperature and humidity, and ozone when used in the natural environment for a long time. In order to evaluate the impact of these environmental factors on the weather resistance of rubber, ozone aging test has become an important testing method. This test can deeply explore the durability and stability of materials in specific environments by simulating the exposure conditions of rubber products in an ozone environment.

[0003] Ozone, as a strong oxidizing gas, reacts with the polymer chains in rubber materials, causing chain breakage, cross-linking and other aging phenomena, thereby accelerating the aging process of rubber. Ozone aging test takes advantage of this. By observing and studying the aging mechanism of rubber materials in ozone environment, we can better understand the law of its performance changes.

[0004] However, there are some problems with existing rubber testing technology. In ozone aging tests, rubber strips are usually placed directly in an ozone chamber for fumigation testing. But this method cannot fully simulate the actual use of rubber. For example, in actual applications, rubber strips may shake and deform due to vibration or external force, and these dynamic factors will affect the aging resistance of rubber. In the ozone chamber, the rubber strips are usually stationary and laid flat, which causes the endurance time in the experiment to be longer than in actual use. Summary of the invention

[0006] To this end, the purpose of the present invention is to propose an ozone fumigation test device, which uses a reciprocating lifting mechanism to simulate the rubber strip being tested in the test chamber. During the test, the rubber strip not only experiences ozone erosion, but also simulates the accelerated aging effect caused by factors such as vibration and stretching in actual use. Such a test design enables the obtained data to more accurately reflect the weather resistance of the rubber strip in the actual environment, thereby greatly improving the practicality and reliability of the test results.

[0060] The steps of the simulation test are as follows: the driving component 601 is operated by connecting the control switch and the power supply, and the driving component 601 drives the rotating shaft 602 to rotate through the reducer, and the rotating shaft 602 drives the main transmission member 603 and the transmission mechanism 606 to rotate during the rotation of the rotating shaft 602. During the rotation of the outer sleeve 6062, the guide rod 6063 is driven to rotate, and the guide rod 6063 is engaged and connected with the driven plate 6071 during the rotation, thereby pushing the driven plate 6071 to reciprocate and rise and fall in the test cavity 10, simulating the shaking of the rubber during the test. During the rotation of the rotating shaft 602, the main transmission member 603 and the auxiliary transmission member 6051 are engaged and connected, and the driven drive shaft 6052 is driven to rotate, and the drive shaft 6052 drives the rotating blades 6053 to rotate, and the rotating blades 6053 will mix the ozone circulating in the test cavity 10 when rotating.

[0061] After the test is completed, the steps of treating the ozone are as follows: after the test is completed, purification particles are added to the purification box 301, and the purification particles fall into the inner filter box 302, and the purification particles are respectively dropped into the filter holes 3032 through multiple groups of inclined filter mechanisms 303, and the ozone is transported to the inner filter box 302 through the inner through pipe 305 and contacts the purification particles to purify the ozone. The purified ozone is finally discharged through the exhaust component 307 as purified gas.

[0062] In summary, the ozone fumigation test device of the embodiment of the present invention uses a reciprocating lifting mechanism to simulate the rubber strip being tested in the test chamber. During the test, the rubber strip not only experiences ozone erosion, but also simulates the accelerated aging effect caused by factors such as vibration and stretching in actual use. Such a test design enables the obtained data to more accurately reflect the weather resistance of the rubber strip in the actual environment, thereby greatly improving the practicality and reliability of the test results.
