Overview

QL-225 Dynamic Static Ozone Aging Test Chamber Product Usage: It can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheaths, etc. Under static tension or continuous dynamic tension deformation, or under intermittent dynamic tension and alternating static tension deformation, it is exposed to a sealed and unlit air containing a constant ozone concentration and a constant temperature test chamber. The test specimen is tested for a predetermined time to evaluate the ozone aging resistance of the rubber from the degree of cracking or other performance changes that occur on the surface of the specimen.

Product Details

QL-225 Dynamic Static Ozone Aging Test Chamber

Product Introduction: This product is used to test the ozone aging resistance of rubber and its products. Ozone has a low content in the atmosphere, but it is the main factor causing rubber cracking. The ozone aging chamber simulates and strengthens the ozone conditions in the atmosphere, studies the effect of ozone on rubber, quickly identifies and evaluates the anti ozone aging performance of rubber and the protective effect of anti ozone agents, and then takes effective anti-aging measures to improve the service life of rubber products.

Product features: This ozone aging test equipment is made of materials and processed using advanced processing equipment in China. The surface of the shell is treated with spray coating, which is beautiful and smooth. The color matching is coordinated and the lines are smooth. The inner liner is designed to be a sealed space without direct sunlight during operation, where samples can be placed for aging tests. It can maintain a constant temperature difference of ± 2 ℃ during testing and is made of imported stainless steel plates. The indoor sample racks, fixtures, conduits, and other accessories are made of materials such as stainless steel that are not easily decomposed by ozone and affect ozone concentration. The sample holder can rotate 360 degrees with adjustable speed.

3、 Test method

Static tensile test
The standard stipulates that the two ends of the sample should be clamped on a fixture, and a tensile elongation of 20% should be selected. The fixture should be installed on a rotating sample holder with a rotation speed between (20-25) mm/S. The test should be conducted at a temperature of (40 ± 2) ℃, a relative humidity of no more than 65%, and a specified ozone concentration. Check the cracking condition of the sample after the specified time. The general selection of ozone concentration is (50 ± 5) × 10-8.
