Steel structure fireproof coating is a kind of coating that can protect steel structure from heat damage in fire. Its function is to prevent steel structure from losing bearing capacity under high temperature, so as to delay the spread of fire and reduce the loss of personnel and property. Steel structure fireretardant coatings are widely used in industrial buildings, commercial buildings, stadiums, high-rise buildings and other large public buildings.

Fase di rilevamento
The following are the specific detection steps:
Spessore: Use a thickness gauge to test the thickness of the coating, the test points should be evenly distributed on the surface of the coating, and the test results should be recorded.

Fire resistance time: The coating was tested using the hot plate method equipment by applying the coating to the hot plate and recording the time it takes for the coating to lose its bearing capacity by heating the hot plate.
Stabilità termica: The coating samples were tested in a hot air circulation furnace. Durante il test, the surface temperature and appearance of the coating were observed to evaluate its thermal stability.
Adesione: The coating samples were tested using an adhesion testing machine to obtain their adhesion parameters to evaluate their adhesion ability.

Densità: Use a densitometer to test the density of the coating, and pay attention to eliminate the interference of bubbles during the test to ensure the accuracy of the test results.
valore del ph: Use a pH meter to test the pH value of the paint. Durante il test, it is necessary to mix the paint sample with water before testing to ensure the accuracy of the test results.
Resistenza ai raggi UV: Use UV radiation equipment to test the coating, durante il test, it is necessary to observe the surface color and appearance of the coating to evaluate its UV resistance.
Anti-corrosion performance: Use the salt spray test chamber to test the coating sample. Durante il test, it is necessary to place the coating sample in the salt spray test chamber to observe whether the coating surface is corroded to evaluate its anti-corrosion performance.
