Stainless steel shelter surface with fluorocarbon paint construction scheme
1. Sanding stainless steel parts with grinding wheels. According to different materials, 200-400# grinding wheels are generally used for grinding. After sufficient grinding, wipe clean with solvent. (The roughness is required to reach about 20um.) Pay attention to the intensity of polishing, do not scratch the substrate, and require no missing places.
2. Spray a special reinforcing agent TH-105 on the treated substrate. Thin spray is required.
two. Fluorocarbon Primer Spraying
1. Spray a fluorocarbon primer (air pressure at 5-8kg/cm2, water-free spray) on a completely dry substrate; the interval is 30min.
2. It is required to spray evenly without leakage. The color should be uniform and consistent. There should be no flowers. Construction cannot be carried out in windy (above Grade 6) and rainy days.
3. The fluorocarbon primer shall be sprayed once and inspected after spraying. If it is found that there are batch scratches or bee eyes on the surface, it must be polished to meet the requirements;
4. Grinding should use 280 mesh or 360 mesh water abrasive paper, grinding should be careful, pay attention to not wear through the film;
5. After polishing, dust removal should be carried out, and the dust generated on the wall surface should be cleaned with a rag. If the dust is not thorough, after the construction of fluorocarbon paint will not be able to achieve a smooth coating;
6. After the fluorocarbon primer is sprayed, the color should be uniform, the gloss should be uniform, the surface of the coating film should be smooth, and there should be no dust and other stains.
3. Fluorocarbon Metal Finish Spraying
1. The primer must be completely dry, and the surface shall be free of dust and other sundries;
2. Construction ratio, main paint: curing agent: thinner = 10:1:2-5;
3. after the deployment of fluorocarbon metal paint must be 100 mesh gauze filter, diluent in the process of placing should be constantly stirred, so as to avoid precipitation;
4. Fluorocarbon metal surface spraying twice;
5. Spray gun model: W-71, nozzle size: 1.5-2.0mm, air pump pressure: 0.3-0.5Mp;
6. During construction, the coordination of spraying number, spraying area, spraying base surface and hanging cage distribution shall be considered. Considering the actual situation of the project, the construction personnel shall be arranged to spray at the same time. Under the premise of ensuring no sagging, the spraying shall be as thick as possible;
7. Anti-pollution and anti-virus work should be done well, and downpipes should be protected. Workers should wear protective equipment such as gas masks and gloves during construction, and fireworks are strictly prohibited;
8. Spraying should be uniform, reasonable density, no sagging, uneven light and shade, flowers and other phenomena, delicate hand feeling, uniform gloss, no batch scratches and uneven phenomenon.
4. Finish Painting
1. The finish paint shall be sprayed on the basis of the finish paint being completely dry;
2. spraying should be uniform, no leakage, sagging and other phenomena;
3. After spraying, it should feel fine, good gloss, uniform color and comfortable appearance.
5. cleaning and sanitation
1. Clean up contaminated places such as glass and downpipes, pay attention to the protection of other finished products, and clean up thoroughly;
2. Clean the living quarters and inventory areas and restore them to their original conditions.
Note: Different users can make appropriate improvements to the roughness and process according to the different nickel content and standard requirements of the material.
