Exterior wall coating testing performance and related equipment
Exterior wall coating is a kind of decorative and protective coating coated on the surface of building exterior walls, mainly used for waterproof, heat insulation, anti-corrosion, beautification and other purposes. It has excellent weather resistance, stain resistance, wear resistance and UV resistance, which can effectively prevent wall corrosion, aging and fading, and improve the overall performance and beauty of the building. Exterior wall coatings are widely used in the decoration and protection of the exterior walls of various buildings such as residential buildings, commercial buildings, industrial buildings and public facilities.
Test performance and instruments
The following are the key properties to be tested and the instruments and equipment to be used:
| Factor of performance | Instruments and equipment |
|---|---|
| Color and gloss | Colorimeter, gloss meter |
| Weather resistance | Spectral radiation test chamber, xenon lamp aging test chamber |
| Pollution resistance performance | Pollutant attachment performance testing equipment |
| Flaking resistance | Peeling testing machine |
| Crack resistance | Crack resistance test equipment |
Thickness of thickness | Thickness measuring instrument |
| Color difference and color change | Color difference meter |

Detection method steps
The following are the properties that need to be tested for exterior wall coatings and their testing steps:
Color and gloss: Test with colorimeter and gloss meter under standard light source and record test results.
Weather resistance: Use spectral radiation test chamber or xenon lamp aging test chamber to test the weather resistance of the coating, and record the test results.
Pollution resistance: Test the pollution resistance of the coating using the pollutant attachment performance testing equipment, and record the test results.

Spalling resistance: Use the spalling testing machine to test the spalling resistance of the coating and record the test results.
Crack resistance: Use crack resistance test equipment to test the crack resistance of the coating and record the test results.
Thickness: Use the thickness tester to test the thickness of the coating and record the test results.
Color difference and color difference change: use the color difference meter to test the color difference and color difference change of the coating, and record the test results.
The above is the key detection performance of exterior wall coating and its corresponding detection method, for reference only.
