O revestimento isolante de parede externa é um tipo de revestimento que combina isolamento térmico, decoração e funções impermeáveis, which is widely used in building exterior wall insulation system. It can effectively improve the thermal insulation performance and energy saving effect of buildings, but also has excellent decorative effect and waterproof performance. Exterior wall insulation coatings are suitable for various types of buildings, including residential, commercial, and industrial buildings.

Principais propriedades e métodos de teste de revestimentos de isolamento de paredes externas

The following are the common key properties of exterior wall insulation coatings and the corresponding testing instruments:

Principais propriedades e métodos de teste de revestimentos de isolamento de paredes externas

The following are the corresponding detection steps for each performance:

Grossura: The thickness of the coating was measured using a coating thickness meter.

Força de ligação: The bond strength between the coating and the base was tested using a tensile testing machine.

Resistência às intempéries: the sample is placed in the xenon lamp aging tester for accelerated aging, and then the performance changes are detected by visual observation, appearance evaluation and other methods.

Crack resistance: The tensile resistance of the coating was tested using a needle prick tester.

Diferença de cor: Use a color comparator to detect the color of the coating.

Densidade: Use a densitometer to test the density of the paint.

Alkali resistance: Use a acidity meter to test the ph of the coating and judge its alkali resistance.
