Învelișul izolator al peretelui exterior este un fel de acoperire care combină izolația termică, funcții de decor și impermeabilizare, 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, comercial, and industrial buildings.

Proprietăți cheie și metode de testare ale straturilor de izolație pentru pereți exteriori

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

Proprietăți cheie și metode de testare ale straturilor de izolație pentru pereți exteriori

The following are the corresponding detection steps for each performance:

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

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

Rezistenta la intemperii: 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.

Diferență de culoare: Use a color comparator to detect the color of the coating.

Density: 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.
