High concentration ozone aging test chamber

High concentration ozone aging test chamberProduct Description

The low content of ozone in the atmosphere is the main factor causing rubber cracking. The ozone aging chamber simulates and strengthens the ozone conditions in the atmosphere, studies the effect of ozone on rubber, and quickly identifies and evaluates the anti ozone aging performance of rubber and the protective effectiveness of anti ozone agents. Effective anti-aging measures are then taken to improve the service life of rubber products

Introduction to the structural design of high concentration ozone aging test chamber

This high concentration ozone aging test chamber is made of high-quality materials and processed using current domestic processing equipment. The surface of the shell is treated with spray coating, which is beautiful and smooth. The color matching is coordinated and the lines are smooth. The inner liner is made of imported high-quality stainless steel plate and adopts a * air duct structure. The indoor sample racks, fixtures, conduits, and other accessories are made of materials such as stainless steel that are not easily decomposed by ozone and affect ozone concentration.

The sample holder can rotate 360 degrees with adjustable speed.

The observation window is made of multi-layer insulated tempered glass with a laminated conductive film on the inside, which has the advantages of heat insulation and is not prone to steam frosting.

The interlayer between the inner container and the outer shell of the equipment is filled with high-density glass fiber cotton to ensure that the box will not experience excessive temperature fluctuations due to temperature conduction, and to maintain a constant temperature of the sample during the testing process.

The equipment uses a long axis fan motor for stirring and a stainless steel multi blade impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation, ensuring uniform and stable temperature in the laboratory.

A double-layer high-temperature resistant high tensile sealing strip is used between the door and the box to ensure the sealing of the testing area. Using non reactive door handles makes operation easier. High quality casters are installed at the bottom of the machine, making it easy to move and fix the machine.

High concentration ozone aging test chamber ozone concentration

The ozone concentration detection adopts a domestically produced ultraviolet ozone concentration analyzer, which adopts the principle of ultraviolet photometric absorption method. The detection range is from 1ppm to 1000ppm, and the measurement accuracy is 0.01ppm or 3% of the displayed value. It can monitor the changes in ozone concentration in the environment in real time. During use, the device automatically calibrates to zero, ensuring the accuracy of concentration and avoiding zero drift. The ozone concentration detector is designed based on the Beer Lambert law, utilizing advanced microprocessor control technology, long-life pulse mode light source, and the characteristic absorption of ultraviolet light by ozone. Has a long design lifespan; Stable data with high accuracy; Easy to use, maintain, and operate. The instrument is equipped with a built-in printer, large capacity data storage, and USB data communication interface for convenient data management and analysis.

The ozone generator adopts a medium frequency high voltage discharge method, which stabilizes the concentration of ozone produced due to the electrode not producing corona overheating, and does not decrease with working time or gas flow rate. No vulnerable components, maintenance free operation, it is a long-life type. Multiple groups can be used in parallel to meet design requirements.
