Nanjing Jinling environmental testing ozone aging test chamber industry leading brand

With the rapid development of modern industrial technology, the application fields of rubber and plastic products are becoming increasingly broad, and the environmental conditions they are subjected to are becoming more and more complex and diverse. Only by reasonably stipulating the environmental conditions of the product and correctly selecting the environmental protection measures for the product can we ensure that the product is protected from damage during storage and transportation and is safe and reliable during use.
Ozone content in the atmosphere is very small but it is the main factor causing rubber cracks. The ozone aging chamber simulates and strengthens ozone conditions in the atmosphere, studies the action of ozone on rubber, and quickly identifies and evaluates the anti-ozone aging performance of rubber. and anti-ozonant protective effects, and then take effective anti-aging measures to extend the service life of rubber products. The imported ozone generator used in the equipment adopts medium frequency and high voltage power supply, and the quartz glass tube electrode is welded. The ozone concentration generated is stable. It is mixed with a certain amount of treated air in the exchanger and sent to the test chamber. The ultraviolet ozone concentration is used. The detector will feedback the continuously detected ozone concentration online to the ozone generator control system, so that the control system can effectively control the generation of ozone according to the set value, so that the test chamber maintains an appropriate ozone concentration. The control system adopts programmable controller. In addition, the heating and humidification system works to meet all temperature and humidity test conditions.
Ozone aging test equipment can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheaths and other products, under static stretching or continuous dynamic stretching deformation, or under intermittent dynamic stretching and static stretching Under alternating deformation, the sample is exposed to a closed, non-illuminated air containing constant ozone concentration and a constant temperature test chamber. The sample is tested at a predetermined time to evaluate the degree of cracks or other performance changes that occur on the surface of the sample. Ozone aging resistance of rubber.
Static tensile test
The standard stipulates that the two ends of the sample are clamped on special clamps, and an elongation rate is selected for stretching. Generally, the clamp is installed on a rotating sample rack, and the sample rack rotates at / During the period, the test is carried out at a temperature of ℃ and a relative humidity not greater than the specified ozone concentration. After the specified time, check the cracks of the sample. General wire and cable ozone concentration selection () -.
