Ozone Chamber, Ozone Concentration: 10~3000pphm, Size: 100 L

Main Purpose of Ozone Chamber: The ozone chamber is mainly used for rubber and plastics resistance to ozone aging test, requires accurate steady-state test capability. Ozone in the atmosphere is rarely the main factors of rubber cracking,
Ozone chamber simulation and strengthening the atmosphere of ozone conditions, the study of the role of ozone on the rubber, rapid identification and evaluation of rubber anti-ozone aging performance and anti-ozone agent Protective effect of the method, and then take effective anti-aging measures to improve the life of rubber products.

Principles and Methods for Ozone Chamber:

● The equipment from the silent high efficiency ozone generator ozone gas and a certain amount of air pump by pressurization, through the glass rotor flowmeter, and adjust the flow of air, in the exchange after mixing into the test chamber, UV detection The instrument will continuously detect the ozone concentration on the line, fed back to the ozone generator control system,

ozone chamber

● So that the control system according to the set value to effectively control the occurrence of ozone, so that the ozone test chamber to maintain the appropriate ozone concentration, by the heating and humidification system to meet all the tests condition.
● Test method According to the test methods and standards can be divided into “static” and “dynamic”, static is the sample is stretched or the product directly into the ozone test chamber to do the test, the dynamic is the sample placed in the test box on the fixture , The floating of the measured sample itself is about 5% ~ 45%.
