Application
Ozone resistance aging test chamber is used to test the characteristics of rubber cracking resistance under ozone environment. Ozone resistance testing machine can control and adjust the concentration of ozone environment to determine the ozone resistance of the specimen.
1.2. Principles and methods
Test methods can be divided into "static" and "dynamic" according to test methods and standards. Static means that the sample is stretched and placed in the test box for testing, while dynamic means that the sample is placed in the test box. On the fixture, do the test while stretching, and the fluctuation of the stretching is about 5%-45% of the tested sample itself
2. Main technical Parameters
2.1. Temperature range: 0℃-80℃
2.2. Temperature fluctuation: ±0.5℃ Temperature distribution accuracy: ±2.0℃
2.3. Ozone concentration accuracy: 10~400pphm ±10%
2.4. Raising frequency of sample rack: 2R/min (optional)
2.5. Air velocity: 12~16mm/s
2.6. Sample rack speed: 360 degree rotating sample rack (rotating speed 1~3 revolutions per minute or optional adjustable)
3. Structural Characteristics
3.1. Structure: One machine.
a) 3.2. Material-inner box: SUS304 stainless steel plate
b) Outer box: SUS304 stainless steel plate or baking varnish (beige white).
c) Thermal insulation: dual protection of rigid polyurethane foam + aluminum silicate thermal insulation cotton.
a) 3.3. Box door-single open door, left open.
b) Two silicone rubber sealing strips for window frame/door frame and anti-condensation electric heating device.
c) Observation window W300xH450mm and lighting lamps are equipped on the doors and windows.
3.4. Requirements of the sample rack
a) (Dynamic experiment; optional)-Fix both ends of the sample with clamps under the required elongation. When in contact with ozonized air, the length of the sample should be basically parallel to the direction of airflow
b) The fixture should be made of a material (such as aluminum) that does not easily decompose ozone.
c) Make the sample rotation speed between (20^-25) mm/s, in a vertical dry air plane, each sample continuously moves along the same path
d) The time for one rotation of the same sample is (8^-12) min. The scanning area of the sample is at least 40% of the effective area of the test box.
e) The sample preparation should meet the requirements of GB/T 9865.1. The sample is best cut from the newly molded test piece, if necessary, it can be cut from the finished product. The sample should be at least 3 samples per test condition. The width of the long standard sample is not less than 10mm, the thickness is 2.0mm±0.2mm, and the length of the sample between the two ends of the clamp before stretching is not less than 40mm.
