The application of architectural coatings in exterior wall decoration accounts for about 60%. The construction industry is the largest area for coating applications and the largest market for fluorocarbon coatings. Fluorocarbon spraying is one type of electrostatic spraying, and the other type of electrostatic spraying is powder spraying.
Fluorocarbon spraying has been applied earlier in the world. In the past few decades, fluorocarbon spraying technology has been widely used in Australia, the Middle East and Southeast Asia such as Singapore, Malaysia and Thailand. In recent years, with the rise of high-end markets, the need for high-standard coatings for building exterior walls has also increased.
As an environmentally friendly coating, the fluorocarbon coating is chemically resistant, resistant to corrosion by strong acids, alkalis, and organic solvents, and its properties such as heat resistance, aging resistance, lubricity, and insulation make it particularly suitable for lining materials for chemical equipment. The anti-corrosion protection, super-duration decoration of outdoor aluminum in high-grade buildings, etc., are widely used in the fields of construction, anti-corrosion, highways, railway bridges, transportation vehicles, ships and marine engineering facilities, and have great application value. Big market space.
Fluorocarbon sprayed profiles as high-grade building profiles
The quality of the entire process is extremely strict
Fluorocarbon spraying process flow introduction
Fluorocarbon spraying equipment has excellent atomization effect, ensuring the uniformity of the sprayed layer. Existing fluorocarbon spray coloring type is rich. The fluorocarbon spraying process uses multi-layer spraying. The types of fluorocarbon spray coating include two coats (primer plus top coat), three coats (primer, top coat plus varnish), four coats (primer, barrier paint, and surface coating). Lacquer and lacquer), strictly control the process from the pre-treatment process, spray process and curing process to ensure the quality of aluminum surface coating.
Fluorocarbon spraying process
Pre-treatment process:
Degreasing of aluminum materials → Washing → Alkali washing (degreasing) → Washing → Pickling → Washing → Chromizing → Washing → Pure washing
❖ spraying process:
Primer → Finish → Lacquer → Baking (180-250°C) → Quality Check
Fluorocarbon paint spray coating type
❖Two layer coating and one bake: pre-treatment → chromate treatment → drying → primer coating → topcoat coating → baking → packaging
❖ Three layer coating:Pretreatment→Chromizing→Drying→Primer Coating→Metal Finish→Varnish→Baking→Packing
❖Four layer coating and Two Baking: Pretreatment→Chromizing→Drying→Primer Coating→Isolating Paint→Baking→Face Coating (Metal Finish)→Clear Coating→Baking→Packing
Chromizing Purpose: A fine and stable chromium film is formed on the surface of aluminum. This film has a certain degree of wear resistance, corrosion resistance and good adsorption capacity, so that the coating in the coating, improve its adhesion.
