Short-term laboratory testing can predict how a material's performance will change under long-term outdoor exposure.
2. Working principle
The UV accelerated weathering testing machine mainly implements its functions through the following three core modules:
| module | Function |
|---|---|
| UV light source | Simulate solar ultraviolet radiation, usually using UVA or UVB lamps |
| Temperature and humidity control system | Adjust the temperature and humidity in the test chamber to simulate different climate conditions |
| sample holder | Secure test specimen to ensure uniform exposure to test conditions |
3. Application fields
UV accelerated weathering testing machines are widely used in many industries. The following are its main application areas:
| Industry | Application scenarios |
|---|---|
| automobile manufacturing | Test the weather resistance of car paint, plastic parts and rubber seals |
| building materials | Evaluate the durability of exterior paint, waterproofing materials, doors and windows |
| Electronic appliances | Test the stability of housing materials, displays, etc. under ultraviolet light |
| Textiles | Check fabric color fastness and fiber strength changes |
