Polyester powder coated aluminum sheet is a special surface-treated aluminum sheet, commonly used in construction, decoration and industrial applications. The process sprays polyester powder coating onto the surface of the aluminum sheet, and then heats and cures it, so that the coating combines with the surface of the aluminum sheet to form a strong and durable protective layer.
The performance of polyester powder coated aluminium sheet is related to the aluminum alloy, state and thickness. The alloys commonly used are 1xxx series (pure aluminum, low strength, corrosion resistance), 3xxx series (aluminum-manganese alloy, high strength, good processability), 5xxx series (aluminum-magnesium alloy, salt spray resistance, medium strength), and 6xxx series (aluminum-magnesium-silicon alloy, high strength, heat-treated and strengthened). The states of powder coated aluminum sheet are O state (annealed, easy to form), H state (work hardening, high strength), and T state (heat-treated and strengthened, high strength and hardness). The thickness is selected according to the scene, 2.0-3.0mm for building curtain walls, 1.0-2.0mm for interior decoration, and 0.5-5.0mm for industry. Reasonable selection can balance decoration and function.
Features of polyester powder coated aluminum sheet:
- Good decorative effect:
Rich and varied colors, various colors can be customized according to needs, including pure colors, metallic colors, etc., and special processes can be used to achieve artistic texture effects such as sand patterns, wrinkles, water patterns, and mesh patterns to meet the requirements of different design styles.
- Strong weather resistance:
It has good weather resistance. After 3000 hours of QUV accelerated aging test without powdering, and more than 1000 hours of salt spray test, it can effectively resist the erosion of environmental factors such as acid rain, air pollution and ultraviolet rays, and can maintain bright colors and stable performance for a long time in outdoor environments.
- Excellent corrosion resistance:
Polyester powder coating can effectively isolate the contact between aluminum sheets and the external environment, prevent aluminum sheets from corrosion, and increase the service life of aluminum sheets. It is suitable for various harsh environments.
- Good mechanical properties:
The coating hardness can reach 2H level, with high wear resistance and scratch resistance. It can resist the collision and friction of external objects to a certain extent and maintain the integrity of the surface.
- Environmental protection and energy saving:
Polyester powder coating does not contain organic solvents, and will not produce volatile organic compounds (VOCs) during the spraying process. It is environmentally friendly, and the powder coating can be recycled and reused to save resources.
Polyester powder coated aluminum sheets are widely used in many fields, including:
- Building curtain walls:
Can be used for exterior wall decoration of commercial buildings, airports, stations, stadiums and other buildings, providing beautiful and durable curtain wall surfaces, while having good weather resistance and waterproof performance.
- Interior decoration:
Suitable for indoor ceiling and wall decoration in office buildings, hotels, clubs, shopping malls and other places, which can create a variety of decorative effects to meet the personalized needs of interior design.
- Household items:
Such as panel materials for furniture, cabinets, doors and windows, etc., have the advantages of beauty, easy cleaning, wear resistance, etc., adding fashion and quality to the home environment.
- Transportation:
Used for external parts of automobiles, ships and other transportation vehicles, providing durable protection.
- Other fields:
Can also be used in industrial equipment housings, automotive parts, electrical product housings and other fields, providing protection and decorative functions.
Polyester powder coated aluminum sheet has become one of the commonly used materials in modern architecture and industrial design due to its excellent performance and appearance. Its weather resistance, corrosion resistance and rich color selection enable it to meet strict requirements in many applications.
