Here we today will briefly describe the application of fluorocarbon sprayed aluminum plate in building curtain wall. Fluorocarbon sprayed aluminum for sale is also called PVDF aluminum plate. Single-layer aluminum sheets, aka PVDF aluminum plates, are widely used in building curtain walls, and the PVDF fluorocarbon coating on the surface is usually formed by spraying process or by roller coating process. This article summarizes the relevant analysis of the rigidity of the commonly used 3mm thick 3003 sprayed plate.
PVDF aluminum plates are widely used in building curtain walls, and the PVDF fluorocarbon coating on the surface is usually formed by spraying process or by roller coating process. The former is to first process the light aluminum plate into a structure with reinforcing ribs and hanging ears through the sheet metal processing process, and then apply the PVDF fluorocarbon coating to the single-layer aluminum plate for the curtain wall. (such as 3003) and Al-Mg alloys (5052, 5754, etc.).
The thickness and alloy type of the PVDF aluminum plate can be selected according to the design needs, and are not limited by the process. The following is an analysis of the rigidity of the commonly used 3mm thick 3003 spray plate.
In the curtain wall structure, the rigidity of the aluminum plate is very important, because the failure form of the PVDF aluminum plate in the curtain wall structure is not the fracture, but whether the aluminum plate has enough rigidity to resist the deformation caused by the external load. Rigidity depends on the thickness of the aluminum plate for sale and the structure of the stiffeners.
The stiffness of the PVDF aluminum plates is specified in JGl02-2003 "Technical Specification for Glass Curtain Wall Engineering".
The stiffness coefficient (D) is calculated based on: D=Et3/12(1-0.332), t is the plate thickness, and E is the elastic modulus.
A1-Mn alloy (3003) E1=70GPAA1-Mg alloy (5754) E2=El=69.3GPA Calculate the rigidity of 3mm thick 3003 aluminum alloy and 2.5mm thick 5754 aluminum plate: D3003/D5754=1.753mm The rigidity of 3003 aluminum alloy is 1.75 times that of 2.5mm5754 aluminum alloy.
From the elastic modulus E value, it can be seen that the 3003 aluminum alloy with the same thickness is slightly more rigid than the 5754 aluminum alloy.
Therefore, many projects, especially high-rise structures and high wind pressure areas, use 3mm thick sprayed aluminum plates (3003). PVDF aluminum plates are used all around the world.
