الخصائص الرئيسية وطرق اختبار الطلاءات العازلة للجدران الخارجية
الطلاء العازل للجدران الخارجية هو نوع من الطلاء الذي يجمع بين العزل الحراري, وظائف الديكور ومقاومة للماء, 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.

The following are the corresponding detection steps for each performance:
سماكة: The thickness of the coating was measured using a coating thickness meter.
رابطة قوية: The bond strength between the coating and the base was tested using a tensile testing machine.
مقاومة الطقس: 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.
مقاومة الكراك: The tensile resistance of the coating was tested using a needle prick tester.
فرق اللون: Use a color comparator to detect the color of the coating.
كثافة: 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.
