Stainless steel surface fluorocarbon paint construction process

1. pre-treatment

1. Sanding stainless steel parts with grinding wheels. According to different materials, 200-400 mesh grinding wheels are generally used for grinding. After sufficient grinding and uniformity, wipe them clean with solvent. (The roughness is required to reach about 20μm.) Pay attention to the strength when polishing, do not scratch the substrate, and there shall be no missing places.

2. Spray a special reinforcing agent X-107 on the treated substrate. Thin spray is required.

two. Fluorocarbon Primer Spraying

1. Spray stainless steel fluorocarbon primer (air pressure at 5-8kg/cm2, waterless spraying) on the completely dry substrate; The interval is 30min.

2. It is required that the spraying should be uniform without leakage. The color should be uniform and there should be no flowers. The holes, joints, edges and 90-degree dead corners that are difficult to paint should be painted with a brush before spraying. In case of rain, snow, fog, frost, wind weather can not construction.

3. Fluorocarbon primer shall be sprayed once. After spraying, inspection shall be carried out. If scratch marks or bee eyes are found on the surface, they must be polished to meet the requirements;

4. Grinding should use 280 mesh or 360 mesh water sanding paper, grinding should be careful, pay attention not to wear through the coating film; After grinding, 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;

5. After the fluorocarbon primer is sprayed, the color should be uniform, the gloss should be uniform, the coating surface should be smooth, and there should be no dust and other stains.

3. Fluorocarbon Metal Finish Spraying

1. The primer must be completely dry, the surface shall not have dust and other debris; according to the main paint: curing agent: diluent = 10:1:2-5 ratio.

2. after the deployment of fluorocarbon paint must be 100 mesh screen for filtration, diluent in the process of placing should be constantly stirred, so as to avoid precipitation;

3. Fluorocarbon metal surface spraying twice; 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. On the premise of ensuring no sagging, the spraying shall be as thick as possible;

7. Spraying should be uniform, reasonable density, no sagging, uneven light and shade, flowers and other phenomena, delicate hand feeling, 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 coating, sagging and other phenomena; spraying should be finished with fine hand feeling, excellent gloss, uniform color, comfortable look and feel.

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.

Remarks: The above source abundant fluorocarbon provides you with the construction technology of stainless steel fluorocarbon paint. Different users can make appropriate improvements to the roughness and technology according to the different nickel content and standard requirements of the material.
