Desempenho de teste de revestimento de parede externa e equipamentos relacionados
O revestimento de parede externa é um tipo de revestimento decorativo e protetor revestido na superfície das paredes externas de edifícios, mainly used for waterproof, heat insulation, anti-corrosão, beautification and other purposes. It has excellent weather resistance, resistência a manchas, 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, edifícios comerciais, 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 | Instrumentos e equipamentos |
