What kind of material is made of aluminum-plastic plate?
Material Aluminum: curtain wall board with material properties should be consistent with GB / T3880.2 requirements of the 3 × × × series, 5 × × × series or better corrosion resistance and mechanical properties of other series of aluminum alloy. Aluminum should be cleaned and chemically pretreated to remove oil, dirt and loose layers of natural formation from contact with air and form a layer of chemical conversion film to facilitate aluminum and coating and Solid bonding of the core layer. Coating: curtain wall coating material should be used weatherability excellent fluorocarbon resin, can also use other performance quite or more excellent material. Note 1: Polyvinylidene fluoride fluorocarbon resin (PVDF), which is excellent in weatherability, is widely used. However, pure PVDF resin should not be directly coated on aluminum, and some other materials should be added as appropriate to change its coating Performance, which constitutes the so-called 70% fluorocarbon resin. Note 2: 70% fluorocarbon resin, refers to the production of aluminum-plastic plate coating used in a variety of raw materials, PVDF resin raw materials accounted for 70%. As the paint is also a pigment and other components and fluorocarbon resin coating is usually a layer of non-fluorocarbon resin primer, so the total thickness of PVDF in the total coating of aluminum-plastic plate is about 25% to 45%. Core material: Ordinary curtain wall board material used in the material properties should be consistent with GB11115, GB11116, GB / T15182 or other corresponding national or industry standards.
Aluminum-plastic composite board is a chemically treated coated aluminum sheet for the surface material, with polyethylene plastic as the core material, in the special aluminum-plastic plate production equipment from the processing of composite materials. The unique performance of the aluminum-plastic composite panel itself determines its wide range of uses: it can be used for building facades, curtain wall panels, retrofits of old buildings, interior walls and ceilings, advertising signs, display stands, engineering. Belonging to a new type of building decoration materials.
