Test de performance des revêtements de murs extérieurs et des instruments et équipements associés
Exterior wall coating is a kind of decorative and protective coating coated on the exterior wall of the building, mainly used for waterproofing, heat insulation, anticorrosion, beautification and other purposes. It has excellent weather resistance, pollution resistance, wear resistance and UV resistance, can effectively prevent wall corrosion, aging and fading, improve the overall performance and beauty of the building. Exterior wall coating is widely used in the exterior wall decoration and protection of residential, commercial, industriel, public facilities and other buildings.

Procédure de méthode de détection
The following are the properties of exterior wall coatings to be tested and the testing procedures:
Couleur et éclat: Testez avec un appareil de mesure de la différence de couleur et un appareil de mesure du lustre sous une source de lumière standard et enregistrez les résultats du test.
Weatherability: Test the weatherability of the coating using a xenon lamp aging chamber or a spectral radiation chamber, et enregistrer les résultats des tests.
Pollution resistance: Use pollutant adhesion testing equipment to test the pollution resistance of the paint and record the test results.
Spalling resistance: Use spalling tester to test the coating’s spalling resistance and record the test results.
Crack resistance: Use the crack resistance test equipment to test the crack resistance of the coating and record the test results.
Épaisseur: Use the thickness meter to test the thickness of the coating and record the test results.
Color difference and color difference change: Use a color difference meter to test the color difference and color difference change of the paint and record the test results.
The above is the key detection performance of exterior wall coatings and the corresponding detection methods, pour référence seulement.
