Thermal insulation coatings and their performance testing
Thermal insulation coating is a coating that is able to reduce heat transfer from the surface of a building or equipment. The main components of thermal insulation coatings include highly reflective pigments and fillers that can reflect and scatter solar and thermal radiation, reducing the absorption and transfer of heat. Thermal insulation coatings can effectively reduce indoor temperature, reduce air conditioning load, extend the service life of buildings or equipment, and can save energy and reduce energy consumption. The application fields of heat insulation coating include buildings, pipelines, storage tanks, ships, וכו ', which plays a positive role in the promotion of environmental protection and energy saving.

Infrared emissivity | The ability of the coating to emit infrared rays |
Resistance to heat | The ability of the coating to block heat conduction |
Durability of life | The durability of the coating in different environments |
Force of adhesion | The degree of bonding between the coating and the substrate |
Resistance to weather | The anti-aging properties of the coating in different climatic conditions |
אַחֵר | Such as coating chemical resistance, water resistance, corrosion resistance and so on |
Thermal insulation coatings and their performance testing
שיטת זיהוי
Reflectivity: Use solar reflectors, radiometers and other equipment to test the ability of the coating to reflect solar and thermal radiation.
Infrared emissivity: Use infrared radiometer, thermal imager and other equipment to test the ability of the coating to emit infrared.
Thermal resistance: Use thermal conductivity meter, thermal resistance meter and other equipment to test the ability of the coating to block heat conduction.
עֲמִידוּת: 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 means of scratch method, stripping method and stretching method.
Thermal insulation coatings and their performance testing
עמידות לתנאי מזג האויר: The anti-aging performance of the coating is tested by artificial accelerated aging test or natural climate exposure.
Others: according to the specific type of heat insulation coating and testing items, select appropriate testing methods and equipment for testing, such as testing the chemical resistance, water resistance, corrosion resistance of the coating, וכו.
The results of these test projects can help to evaluate the quality and suitability of the thermal insulation coating and how well the performance will perform in practical applications. The test method and equipment are different according to the specific type of insulation coating and the test item. The performance tests of thermal insulation coatings need to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results. באותו הזמן, the scope of application and accuracy of different detection methods are also different, so appropriate methods and equipment should be selected before the test, and adequate sample preparation and test scheme design should be carried out.
