A thermal insulation coating is a coating that reduces heat transfer from the surface of a building or equipment. The main components of thermal insulation coatings include high reflectivity pigments and fillers, which can reflect and scatter solar and thermal radiation, reducing heat absorption and transfer. Thermal insulation coatings can effectively reduce indoor temperature, reduce air-conditioning load, prolong the service life of buildings or equipment, and can save energy and reduce energy consumption. The application fields of thermal insulation coatings include buildings, pipelines, storage tanks, ships, etc., which play a positive role in the promotion of environmental protection and energy saving.

Detection method
Reflectivity: Use solar reflectometers, radiometers and other equipment to test the ability of coatings to reflect solar and thermal radiation.
Infrared emissivity: Use infrared radiometers, thermal imaging cameras and other equipment to test the coating's ability to emit infrared rays.
Thermal resistance: Use thermal conductivity meter, thermal resistance meter and other equipment to test the barrier ability of the coating to heat conduction.
Durability: Accelerated aging test, constant temperature and humidity test and other methods are used to test the durability of the coating in different environments.
Adhesion: The degree of bonding between the coating and the substrate is tested by cross-hatch method, peeling method, tensile method and other methods.
Weather resistance: test the anti-aging performance of the coating through artificial accelerated aging test or natural climate exposure.
Others: According to the specific types of heat insulation coatings and testing items, select appropriate testing methods and equipment for testing, such as testing the chemical resistance, water resistance, and corrosion resistance of the coating.
The results of these test items can help evaluate the quality and suitability of the insulation coating, and how it will perform in the actual application. The test methods and equipment vary according to the specific types of heat insulation coatings and test items. The performance test of thermal insulation coatings needs to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results. At the same time, the scope and accuracy of different detection methods are also different. Therefore, appropriate methods and equipment should be selected before testing, and adequate sample preparation and test plan design should be carried out.
