Introduction of ozone aging tester

NOKI Chamber pm9:21

Ozone aging tester, also known as “ozone aging test chamber”, can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheathing, and other products, under static tensile deformation, exposed to air and constant temperature test chamber containing constant ozone concentration in a sealed, non-lighted environment, and tested on the specimen for a predetermined period of time to assess the ozone resistance of rubber from the degree of cracking or other performance changes that occur on the surface of the specimen. The test specimen is tested for a predetermined period of time in an airtight chamber containing constant ozone concentration and constant temperature.

Basic principle

The content of ozone in the atmosphere is very little but the main factor of rubber cracking, the ozone aging chamber simulates and strengthens the ozone conditions in the atmosphere, studies the law of ozone action on rubber, quickly identifies and evaluates the ozone-resistant aging performance of rubber and the method of anti-ozonant protection effectiveness, and then takes effective anti-aging measures to improve the service life of rubber products.

Technical parameters

1、Temperature range :0℃~70℃

2、Humidity range :≥65%R.H

3、Ozone concentration :0~200PPm、0~500PPm

4、Temperature fluctuation :±0.5℃

This equipment applies to vulcanized rubber or thermoplastic rubber under static tensile or dynamic tensile strain conditions, exposed to air containing a certain concentration of ozone and

The test of ozone cracking resistance is carried out at the specified temperature and in the environment without the direct influence of light. The ozone resistance of different rubber materials varies significantly with ozone concentration and temperature, and the degree of damage caused by ozone in the ozone test and the products in use under tensile strain varies greatly depending on the size, type, and strain size.

Working principle of ozone aging tester

With the rapid development of modern industrial technology, rubber, and plastic products in an increasingly wide range of applications, the environmental conditions experienced are becoming increasingly complex and diverse. The only reasonable environmental conditions for the products are specified, the correct choice of environmental protection measures for the products to ensure that the products are safe and reliable in the storage process without damage during transportation.

The concentration of ozone in the atmosphere is rarely the main factor of rubber cracking and ozone, strengthen the aging test chamber to simulate the atmosphere, study the rules of rubber, quickly identify and evaluate the anti-aging performance of rubber ozone to ozone conditions and anti-ozone, ozone protector efficacy method, then take effective anti-aging measures to improve the service life of rubber products. Constant temperature and humidity machine xenon lamp aging tester ozone aging tester imported equipment use an ozone generator, high voltage power supply frequency, quartz glass tube electrodes, in the stability of the ozone concentration caused by, mixed with a certain amount of air into the chamber, ultraviolet ozone concentration detector used by the switchboard to deal with the detected ozone concentration are not in line, back to the ozone generator control system, set the control system based on the basis to The value of the ozone chamber to maintain proper centralized and effective control of the event. The control system uses a PLC programmable controller. Another heating and humidification system works to meet the full conditions of temperature and humidity testing.

The ozone aging chamber can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation, and sheathing, etc. The products are subjected to static or dynamic tensile deformation stretching continuously or intermittently under alternating dynamic stretching and static tensile deformation in a constant chamber containing a closed air and ozone chamber without light irradiation, and the degree of change of the reporter from the test sample surface cracks or other properties of the sample occurring at a predetermined time to evaluate ozone-resistant rubber aging.
