What are the fluorocarbon spraying processes for aluminum honeycomb panels? Today, the technical staff of the aluminum honeycomb panel company will give you an introduction. I hope our introduction can help you better.
1. The purpose of pre-treatment: before the aluminum alloy profiles and plates are fluorocarbon sprayed, the surface of the workpiece must be degreased and decontaminated and chemically treated to produce a chrome film, increase the bonding force of the coating to the metal surface, and prevent oxidation Conducive to extending the useful life of the paint film.
2. Primer coating: As a primer coating for a closed substrate, its role is to improve the coating's anti-penetration ability, enhance the protection of the substrate, stabilize the metal surface layer, and strengthen the adhesion between the topcoat and the metal surface. The color uniformity of the top coat is guaranteed. The thickness of the paint layer is generally 5-10 microns.
3. Topcoat coating: The topcoat coating is the key layer of the fluorocarbon spray coating, which is to provide the decorative color required by aluminum, to make the appearance of aluminum meet the design requirements, and to protect the metal surface from the external atmosphere, acid rain. , The erosion of pollution, preventing UV penetration. The anti-aging ability is greatly enhanced. The top coat is the thickest layer of fluorocarbon spray coating, and the thickness of the paint layer is generally 23-30 microns.
4. Finishing paint coating: Finishing paint coating is also called varnish coating. Its main purpose is to more effectively enhance the anti-erosion ability of the paint layer, protect the topcoat coating, increase the metallic luster of the topcoat color, and make the appearance more colorful. Bright and dazzling, coating thickness is generally 5-10 microns. The total thickness of the trifluorocarbon spray coating is generally 40-60 microns, which can be thickened for special needs.
5. Curing treatment: The trifluorocarbon spray coating generally needs secondary curing. The aluminum material enters the curing furnace for processing. The curing temperature is generally between 180 ℃ -250 ℃. The curing time is 15-25 minutes. Will provide the best temperature and time according to their own coatings. Fluorocarbon spraying plants (Emu Oil Plant) have also changed the two-curing in three-spraying to one-curing according to their own experience.
6. Quality inspection: The quality inspection shall be in accordance with AAMA-605.02.90 standard. Strict quality inspection can guarantee high-quality spray products.
