dustproof exterior wall panel, PVDE aluminum veneer, 3d acoustic diffuser wall panel
Characteristic:
Aluminum curtain wall adopt high-quality and high strength aluminum sheet .It's common thickness is 2.0mm ,2.5mm ,3.0mm ,and its model is 3003. And its state is H24 . Its general material’s maximum dimension is 1220mm*2440mm , and its structure is composed of front-panel , reinforced rib,and angle . Front-panes is directly flexed , and then stamped to form and angle bracket; it also can be formed by riveting angle bracket on the panel’s flanging . Reinforced rib is jointed with electric welding bolt behind plate in order to form a firm structure . So , it can strengthens aluminum curtain wall’s strength and rigidity , and ensures its flatness and ability to resist wind and shock during its long-term use . If need additional sound insulation and heat preservation effects , the special materials can be fixed inside the aluminum sheet.
Surface Treatment:
Aluminum curtain wall veneer surface generally chromized , adopting fluorocarbon spraying processing . Fluorocarbon coatings and varnish polyvinylidene fluoride resin(KANAR500).Generally divided into first coating , second coating , third coating or fourth coating . Fluorocarbon coating has excellent corrosion resistance and weather ability, resistant to acid rain , salt fog and various air pollutants , resistant to cold resistance , can resist strong ultraviolet radiation , can be kept for a long time does not fade , not power , long service life . Our factory use world-renowned fluorocarbon paint manufacturers PPG , DNT , AKZO , NIPPON companies such as the quality of fluorocarbon paint , color choice is broad , customers can directly by the manufacturer to provide color swatches palette selection or provide samples.
PVDF fluorocarbon resin principles:
Our factory mainly recommend and use Dutch aksu , Korea labor-friendly fluorocarbon coatings , Many engineering use show that the Netherlands aksu , Korea labor-friendly fluorocarbon coating indicates that it is A good option.
