Fluorocarbon spray in aluminum profile processing process flow

- Jul 13, 2018 -

Fluorine carbon spraying spraying process include: spray paint to paint, the paint coat to bake (180-250 ℃), quality inspection. The construction process of fluorocarbon spraying varies with different materials. Following Kaixin would like to introduce the process flow of fluorocarbon spraying in aluminum profile processing.

1, aluminum processing first processing in aluminum sheet, prior to coating, the surface should pass to oil decontamination and chemical treatment, to produce chromium film, surface coating and metal bonding strength and oxidation resistance is conducive to extend the lifespan of the paint film.

2, aluminum door profile machining of primer coating: as a substrate, closed primer coating, the effect is to improve the penetration resistance of the coating, strengthen the maintenance of substrate, stable metal surface layer, strengthen paint and metal surface adhesion, can ensure that the color of the paint coating uniformity, paint layer thickness for 5-10 microns.

3, paint coating in aluminum processing, spray coating, paint coating is one of the key layer, is needed to provide aluminum decorative color, make the aluminum appearance to meet the design required, and maintenance of the metal surface is not affected by external environment atmosphere, acid rain and pollution, prevent the ultraviolet rays penetrate. The coating is the thickest coating in spraying. The thickness of coating is generally 23-30 microns.

4, aluminum processing, and the finishing paint coating is also called the varnish coating, the main purpose is to more effectively enhance paint layer of the erosion resistance, maintenance of paint coating, increase the metallic paint color, look more colorful, brilliant, coating thickness for 5 to 10 microns in general. The total thickness of the three coating layers is generally 40-60 microns, which can be thickened if needed.

5, aluminum processing of curing processing: three spray coating generally need a second curing, aluminum processing into curing furnace, usually in the curing temperature of 180 ℃, 250 ℃ between, curing time is 15 to 25 minutes, different fluorocarbon paint manufacturers, can according to your own coating, provides the best temperature and time.

6. Quality inspection in aluminum profile processing: the quality inspection shall be in accordance with AAMA - 605.02.90 standard. Strict quality inspection can guarantee high-quality spraying products.
