Fireproof coating is a special coating that can form an insulating layer on the surface of a material to prevent the spread of fire. It is usually composed of fire-resistant pigments, 树脂, thinners and other materials. Fireproof coating is widely used in buildings, 船舶, subways, tunnels and other fields, can improve the fire rating of these places, reduce the fire loss to personal property.

Test performance and instrument
The following is the key performance of fire retardant coatings to be tested and the equipment to be used:

防火涂料的关键测试性能及测试方法
Procedure of detection method
The following is the performance of fire retardant coatings to be tested and its testing steps:

Combustion performance: Use vertical combustion tester or horizontal combustion tester to test the combustion performance of paint, and record the test results.

防火性能: Use fire resistance testing equipment to test the fire resistance of coatings and record the test results.

热稳定性: Use thermogravimeter or thermogravimetric analyzer to test the thermal stability of coatings and record the test results.

耐水性: Use water penetration test equipment and soaking test equipment to test the water resistance of the coating, and record the test results.

附着力: The coating adhesion to the substrate was tested using the grid tester and the stripping tester, and the test results were recorded.

耐磨性: Wear testing machine, friction testing machine and impact testing machine are used to test the wear resistance, friction resistance and impact resistance of the coating, and the test results are recorded.

Color and luster: Test with color difference meter and luster meter under standard light source and record the test results.

For some special coatings, it may be necessary to use other instruments and equipment for testing, and the specific operation steps will be different.
