What are the relevant characteristics of the ozone aging test chamber?

The ozone test chamber consists of an ozone generator, a fan, a baffle, a specimen holder and a specimen chamber. Ozone generators utilize a high-voltage transformer to discharge electricity through a grid. The generator is placed in front of a low-voltage fan.

Ozone is injected into the test chamber via a bulkhead system. The specimen holder is a detachable clamp mounted on a wire slip ring and can be adapted to a wide range of specimen sizes.

It is typically equipped with a high-efficiency ozone generator, controller, closed-loop ozone concentration control, and a rotating specimen holder (e.g., standard group) that can accommodate up to 24 specimens. With simple settings, pre-set parameters and current parameters can be displayed on the screen, which increases the maneuverability of the device and the accuracy of the test results.

The ozone aging test chamber has just been recognized by customers and the rubber industry. No matter how high-quality the equipment is, we need to constantly maintain, carefully check, understand and pay attention to some related matters in order to make the equipment better play the role of the machine. So what do we need to pay attention to in the ozone aging test chamber, and how to avoid some unnecessary things from happening, the following is the content to be shared:

1. When the ozone aging test chamber is tested, it is necessary to arrange personnel to guard it to prevent accidents;

2. If there is abnormal condition or odor in the laboratory, it should be stopped for inspection;

3. Regular dust removal, because too much dust accumulation will lead to the problem of equipment accuracy decline, but in order to ensure their own safety, before each dust removal work, we must ensure that the power supply of the equipment is in a state of cut-off;

4. The replacement of parts and components is getting longer and longer with the use of the equipment, and a small part of the wearable parts need to be replaced in time, otherwise the equipment may fail and affect its test flexibility;

5. The ozone aging test chamber is mainly used to detect rubber products, and residues are easy to appear in the test, so the chamber needs to be cleaned after each test, so as to avoid the remaining residues affecting the next test results;

In the past year, with the increasing development of industrial technology, the rubber industry has developed a lot, such as plastic toys, rubber gloves and other products, which shows that rubber products are indispensable products for human society; Therefore, the concept of environmental testing is becoming more and more vigorous, and more and more test equipment is put on the stage of scientific development. As the name suggests, the ozone aging test chamber is a test equipment that simulates or accelerates the aging scenario of ozone in the atmosphere on rubber to identify the weather resistance of products.

1.The equipment must be placed in a horizontal position and be equally good and not protected against flammable or explosive materials around it; The power supply should be equipped with an overloaded fuse device in the power supply line, which is only used by this equipment to ensure that the equipment has a good grounding device, which not only ensures the safety of the tester, but also ensures that the equipment is lifespan.

2.An iron shell knife switch should be installed in the power supply line, for this box special, please check the electrical performance of the box before the shell is grounded and energized, and should pay attention to whether there is a broken circuit or leakage, this instrument has no explosion-proof device, and shall not be put into flammable and explosive materials to dry.

3.Before the experiment, the samples are numbered one by one, and then the samples are placed on the sample carousel, so that they do not contact and collide with each other, so as to ensure that the ozone is tested at a uniform concentration with each sample during the test.

4.Close the door when the above points are completed. Turn off the switches of the control system, plug in the power supply plug and open the power switch turntable that will automatically rotate, and the power indicator of the control system will be lit at the same time, if the temperature must be turned on, the switch must be turned on (that is, the high temperature switch and the low temperature switch), and then adjust the fully automatic control system.

The above four points are some things that need to be paid attention to in the daily use of the ozone aging test chamber, I hope that after reading this article, we can better use the equipment, and bring more accurate test results for our own tests.

In recent years, with the rapid development of science and technology, the demand for environmental testing in various industries has become more and more extensive. The research and development of new materials is rising sharply, and in order to meet the various weather resistance of new materials and the adaptability of special environments, more and more test equipment has been put on the stage of scientific development. Today, I would like to introduce an ozone aging test chamber that is deeply loved by the rubber and plastic industries.

The ozone aging test chamber is a test equipment that simulates and accelerates the aging damage of ozone in the atmosphere to plastics, rubber and other items to identify the resistance performance of products. Its shell is made of cold plate spraying, 304 stainless steel liner, and PT100 platinum resistance temperature measuring body; The ozone sensor is from ECO and 2B technology; It is equipped with a gas purifier, a thermostatic bath, an activated carbon absorption and a silica gel drying tower; The device is also designed with a clear and transparent observation window for easy observation at any time.

The studio of the ozone aging test chamber has an air duct interlayer on three sides, and the distribution of heating humidifiers, circulating fan blades and other devices, and the upper layer of the test chamber is equipped with a balanced exhaust hole, which needs to continuously discharge the gas in the test chamber and maintain the balance of the gas concentration in the test chamber.

Compared with similar equipment, the most significant feature of the structure and performance of this equipment is that the ozone concentration is directly displayed by LED digital, and the test ozone concentration can be arbitrarily set within the range and can be accurately controlled, and has the functions of convenient operation, intuitive display and time control, over-temperature protection, short-circuit protection, audible prompt and automatic power cut-off.

The shell of the test chamber is made of high-quality cold-rolled plate electrostatic spraying, the inner tank is made of SUS304 high-quality stainless steel, equipped with centrifugal high-quality aluminum alloy fan blade, which has the characteristics of light weight, which ensures that the motor will not shake when running, and the heater is equipped with a heater under the fan blade, and the heater is made of high-quality nickel-chromium wire, which is fast in the heating process, so as to ensure the stability of the temperature of the box and achieve a more ideal effect of uniform test temperature.

The main safety system of the ozone aging test chamber includes over-temperature protection function, automatic shutdown function when the system alarms, sound prompt function, timing function, and the entire ozone gas generation and detection and capture are sealed circuits to ensure the safety of users in use.

I don't know if you have noticed in your life that some inferior plastic products are prone to fade and yellow or crack and become brittle after a period of use, which is called ozone aging, of course, this phenomenon can also be quickly presented through the ozone aging test chamber.

Although the ozone content in the atmosphere is relatively low, it is the main culprit that causes the cracking and aging of rubber and plastic products, according to statistics, the economic loss caused by the aging of items caused by ozone is hundreds of millions every year. In order to eliminate this kind of ozone loss, people have begun to improve the resistance of products to ozone aging, and the birth of ozone aging test chamber is to achieve product quality identification or screening by simulating and accelerating the aging of items. By understanding the mechanism of ozone aging, the performance indicators of the product are analyzed, so as to carry out targeted anti-aging treatment for the product.

The aging phenomenon of ozone on rubber is manifested in the surface layer of the product at the beginning, especially at the stress concentration or at the interface between the particle and the rubber, and the film will crack; When used under dynamic conditions, the film is more likely to age and crack to reveal new surfaces, so that ozone aging continues to develop in depth until it is completely destroyed.
