1. Different raw materials
The clear water formwork is a kind of building formwork. In northern China, it is made of high-quality birch, poplar and other plates. In southern China, it is made of pine, fir, eucalyptus and other plates. The surface is impregnated with waterproof phenolic resin and hot pressed at high temperature to form a wood plywood formwork. Its surface is smooth and smooth.
The coated plate is coated with a layer of film on the aluminum alloy substrate. It is composed of high gloss film or magic color film, coated with professional adhesive.
2. Different performance
When pouring concrete components with fair faced formwork, not only the rigidity and flatness specified in the specification, but also the smoothness shall be met. Generally, the surface does not need to be plastered for decoration, which can speed up the construction period and save the plastering time and cost. The fair faced formwork is light in texture, and is mainly applicable to the formwork of shear walls, vertical wallboards, dam tunnels, overpasses, arch bridges and other bridge beams and columns in high-rise buildings.
The surface of the coated board is made of imported coated paper through precision machining, which has high flatness and smoothness and is easy to demould. After the formwork is removed, the concrete surface is flat and smooth, which can avoid the secondary plastering process, reduce the cost and shorten the construction period. It is light in weight, easy to cut and nail, good in construction performance and improve the construction speed.
