color coated aluminum sheet coil for composite panel
1. Product Introduction
Aluminum-composite panels or aluminum-plastic plate is made of aluminum plate through surface treatment, coating and a series of compounded new materials processing technologies. It uses aluminum plate as the surface of the lacquer, and polyethylene plastic as core layer. DongChuan color coated aluminum coil, whose surface can be coated with fluorocarbon or polyester coating according to customer request, has various colors and complete specifications and is a kind of ideal material for aluminous model board manufacturer.
Aluminum corrugated composite board can be aluminum alloy panel, vacuum composite plate and aluminum corrugated core of aluminum composite panel. DongChuan color coated aluminum coil, whose surface is coated with fluorocarbon coating and has excellent weather resistance, not only has excellent workability but also can satisfy various processing requirements, such as cutting, connecting and bending requirements. Therefore, it is a kind of ideal aluminum alloy material for manufacturing corrugated composite board.
Aluminum alloy sheet is adopted for both inside and outside layers of aluminum honeycomb panel and intermediate sandwich for hexagonal aluminum honeycomb core. Honeycomb core is compounded of structural adhesive and aluminum alloy surface plate through bonding. DongChuan color coated aluminum coil is the first choice for manufacturing aluminum honeycomb. Its surface can be coated with polyester or fluorine carbon coating according to required color of customer, and its back coating is epoxy.
Painted aluminum sheet is adopted for surface of insulation board of metal exterior wall. Veneer and color of Aluminum plate can be chosen according to design requirements. It has sound decorative effect, weather resistance, corrosion resistance and self-cleaning function, etc; rigid polyurethane foam featuring with excellent heat preservation and heat insulation performance is adopted for middle layer.
