How to determine the thickness of anticorrosive paint for steel structure?
The thickness of the anticorrosive paint of steel structure mainly depends on the following factors: 1. The corrosion factors of the environment in the workpiece include: insolation, salt fog, humidity, high temperature, acid base, grease, etc.. 2. The useful life of the steel structural parts. 3. Varieties of anticorrosive paint for steel structure. Different anticorrosive paint has different best film thickness, different environment for paint thickness requirements are not the same. For example, outdoor environment, the normal thickness of fluorocarbon paint over 35 microns, on the ratio of the 100 micron alkyd enamel. In summary, in the absence of Design Institute gives reasonable paint anticorrosion under the condition that the recommendations of the Advisory sales engineer to paint the Forbidden City, the Forbidden City to provide you with professional, steel structure anticorrosion paint matching scheme of different price, in order to achieve a reasonable price, satisfactory effect of anti rust anti-corrosion of steel structure.
Test method: check with dry film thickness tester. Each component detection 5, each value is the average of the 3 measuring points are 50mm coating dry film thickness.
When the design does not require the coating thickness, the total thickness of the coating should be 150 m, and the room shall be 125 m, the allowable deviation is -25 mu m. The allowable deviation of the dry paint film thickness per time is -5 mu m." Check quantity: according to the number of components, check 10%, and similar components should not be less than 3 pieces.
