What is an ozone resistance testing machine?
In the fields of industrial production and material research and development, the ozone resistance testing machine is an important environmental simulation equipment used to test the aging resistance of materials in an ozone environment. With the widespread application of rubber, plastics, coatings and other materials, the demand for ozone resistance testing machines is also growing. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of ozone resistance testing machines.
1. Definition of ozone resistance testing machine
The ozone resistance testing machine is an experimental equipment that simulates an ozone environment. By controlling ozone concentration, temperature, humidity and other parameters, it accelerates the aging process of materials and evaluates their ozone resistance performance. This equipment is widely used in rubber, plastics, wire and cable, auto parts and other industries.
2. Working principle of ozone resistance testing machine
The ozone resistance testing machine generates ozone through an ozone generator, introduces it into the test chamber, and contacts the test sample. The equipment simulates ozone corrosion conditions in the actual use environment by adjusting ozone concentration, temperature and humidity. After the test is completed, the ozone resistance of the material is evaluated by analyzing the physical property changes of the sample (such as cracks, discoloration, strength loss, etc.).
3. Application fields of ozone resistance testing machine
Ozone resistance testing machines are mainly used in the following fields:
| Application areas | Test materials | Test purpose |
|---|---|---|
| Rubber industry | Tires, seals, hoses | Evaluate ozone aging resistance |
| plastic industry | Plastic film, packaging materials | Test resistance to ozone corrosion |
| Wire and cable | insulation material | Verify long-term safety |
| Auto parts | Rubber seals, plastic parts | Ensure durability and reliability |
4. Comparison of popular models in the market of ozone resistance testing machines
The following is a comparison of the popular ozone resistance testing machine models and their main parameters on the market recently:
| Model | Ozone concentration range | temperature range | Humidity range | Applicable standards |
|---|---|---|---|---|
| OZ-100 | 50-1000pphm | Room temperature-70℃ | 40-95%RH | ASTM D1149 |
| OZ-200 | 100-2000pphm | Room temperature-80℃ | 30-98%RH | ISO 1431 |
| OZ-300 | 200-3000pphm | Room temperature-100℃ | 20-98%RH | GB/T 7762 |
5. Suggestions for purchasing ozone resistance testing machine
When purchasing an ozone resistance testing machine, you need to consider the following factors:
