Specifications and models
● Working chamber size** Preface
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 specifying the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environmental testing of rubber and plastic products is an indispensable and important link to ensure their high quality. The artificial simulated environment test is a scientific summary of the actual environmental impact, and has the characteristics of being typical, standardized, easy to use and easy to compare. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
The damage to materials caused by temperature and moisture has attracted people's attention. Today, our industrial technology is becoming more and more developed, and it is also causing more and more serious damage to the natural environment. Various corrosive gases caused by various manufacturing industries are mixed in the air, such as ozone. Its destructiveness is very serious for materials or products. test.
This ozone aging test equipment can be used to deform rubber products such as vulcanized rubber, thermoplastic rubber cable insulation sheaths and other products under static stretching or continuous dynamic stretching deformation, or under alternating intermittent dynamic stretching and static stretching. The sample is exposed to a closed, non-illuminated air containing constant ozone concentration and a constant temperature test chamber for a predetermined time to detect cracks or other changes in properties on the surface of the sample to evaluate the ozone aging resistance of the rubber.

Tensile test
The standard stipulates that the two ends of the test specimen are clamped on special fixtures. Select an elongation rate for stretching. Generally, the fixture is installed on a rotating sample rack. The rotation speed of the sample rack is between / The test is carried out at a specified stretching rate of the clamp at a temperature of a specified ozone concentration or by cyclic stretching and reset and rotating with the sample holder. After the specified time, check the cracks of the sample. Generally, the ozone concentration selection can also adjust the ozone concentration according to the pre-agreed concentration.
