Construction process of fire-resistant coating for steel structures in petrochemical plants
Thread Content
The image below shows the application structure layer of the thick-coat anti-corrosion coating on a petrochemical plant. First, metal surface treatment – attaching nails and setting up a mesh – spraying a fireproof layer – applying a plaster layer – applying a coating sealant layer – final render.
The construction steps are as follows: 1. Metal surface treatment: Clean the metal surface to ensure it is free of dust and rust. 2. Nail attachment and mesh hanging: Nails are attached to the metal surface and a mesh is hung there to enhance the adhesion of the coating. 3. Apply fireproof coating: Use specialized equipment to evenly spray the fireproof material. 4. Finish coating: Apply a finish layer on top of the fire-resistant layer to make the surface smoother. 5. Coating sealant layer: Apply a sealant layer on the plaster layer to prevent moisture from penetrating. 6. Effect image: Check the overall effect to ensure the coating is even and free of defects. .
