[0002] In recent years, with the widespread application of steel structures in engineering, the metal surface treatment technology of steel components has also developed rapidly. Pretreatment plays an extremely important role in surface treatment technology and engineering. Among them, degreasing, rust removal, phosphating, rust prevention, fire prevention and other matrix pretreatment are metal coating technologies. In addition, by applying a layer of fire retardant coating on the surface of the steel structure, the high temperature effect in the fire scene can be effectively blocked, ensuring that the steel structure always maintains a relatively low temperature state, improving the fire resistance of the building structure, and reducing the fire impact of the building. The thickness detection auxiliary tool is used to detect whether the thickness of the fire retardant coating meets the standard;
