Overview

QL-100 Low Concentration Ozone Aging Test Chamber $r $n 1. Product Application: 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 air containing constant ozone concentration and a constant temperature test chamber without light exposure. The samples are tested for a predetermined time to evaluate the ozone aging resistance of rubber from the degree of cracking or other performance changes that occur on the surface of the samples.

Product Details

QL-100 Low Concentration Ozone Aging Test Chamber

1、 Product use: 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 sealed and unlit air containing a constant concentration of ozone and a constant temperature test chamber. The samples are tested for a predetermined time to evaluate the ozone aging resistance of the rubber by detecting the degree of cracking or other performance changes that occur on the surface of the samples.

2、 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. General selection of ozone concentration (50 ± 5) × 10-8.

Dynamic tensile test:
The standard stipulates that the sample fixture can automatically stretch and reset the sample, with a stretching frequency of 0.5 ± 0.025Hz. The two ends of the sample are clamped on the fixture, and the sample is cyclically stretched from 0 to the maximum elongation. The fixture is installed on a rotating sample holder, with a rotation speed of (20-25) mm/S. At a temperature of (40 ± 2) ℃, a relative humidity of not more than 65%, and a specified ozone concentration, the fixture is cyclically stretched and reset and rotated with the sample holder for testing. After the prescribed time, check the cracking condition of the sample, and generally select an ozone concentration of (50 ± 5) × 10-8;
