Film Faced Plywood

Here is the production process of film-faced plywood:

• Step 1: Choose raw materials like poplar or eucalyptus logs and debark them before sectioning into appropriate lengths.
• Step 2: The logs are placed in the peeling machine to produce chips of required parameters, including size and thickness (wood chips are divided into various parameters A, B, C, etc.).
• Step 3: Wood chip drying: The wood chips may be air-dried or dried in a dryer. Due to the hot and humid climate in Linyi, many manufacturers prefer to do outside drying to conserve fuel.
• Step 4: Wood chip gluing: In most cases, manufacturers opt for a gluing machine to apply adhesive evenly on both sides of the filler board.
• Step 5: Typesetting: Most of the time, this operation is performed manually, and in this process, the thickness of the component is mostly established. In turn, it will be thin blocks, then the horizontal is turned into a solid block, then the vertical is flipped and crossed in this way until the thickness we want.
• Step 6: Cold pressing: This helps to suppress the board into shape and also bind the wood chips together.
• Step 7: Upon the completion of cold pressing, the board will be placed on the hot press for reinforcing the board structure permanently.
• Step 8: Place the plywood board in the sander for smoothening.
• Step 9: Stick the film paper on the board and then place it in a hot press for hot pressing to complete the operation.
• Step 10: In the last process, the board is cut as per the requirement, and the defective boards are selected and removed.

Because of its superb finish and high performance, film faced plywood is widely used for various concrete works, such as high speed railway construction, subway systems, airport ports and in many infrastructure applications – shear walls, vertical wall panels, bridges, dams and tunnelling, building works, general commercial engineering and so on.

Film faced plywood is very suitable for horizontal formwork, shear wall, vertical wall panel, bridge, dam, tunnel and beam column formwork in high-rise buildings.
Before use, a layer of release agent should be evenly applied on the surface of the plywood to facilitate demoulding and surface cleaning, extend the service life of the formwork, and improve the surface quality of the concrete.
The wooden squares close to the template should be laid vertically. The board gaps should be minimized as much as possible, and the boards should be flat. The specifications of the wooden squares are 5 x 10 or 10x 10cm. The board gaps are filled with putty or sealed with adhesive tape to prevent leakage
Slurry and slurry from contaminating the board edges. It is strictly forbidden to collide with hard objects, hit with crowbars, and drag steel bars on the board surface.

1. The top formwork first lays the wooden squares horizontally on the scaffolding. The spacing is 1.2m. Then the wooden squares are vertically pressed with a spacing of 0.4-0.6m. When the thickness of the poured concrete exceeds 200mm; the spacing should be appropriately reduced.
2. Wall formwork: Lay three wooden squares longitudinally behind the formwork, and connect two wooden squares horizontally, leaving space for through-wall screws, and erect diagonal braces. If conditions permit, steel ribs can be used to connect horizontally to form a combined large wall formwork, which can be directly hoisted. Single formwork can be disassembled and replaced.
3. Cut the beam and column formwork according to size, leaving space for through-wall bolts on the top. The column formwork can be locked on all four sides with a short scaffold, and erect diagonal braces.

After the formwork is disassembled, it should be cleaned immediately with non-metallic tools such as brushes, plastic wooden scrapers, etc., and then padded with wooden squares, with the edges and corners aligned and stacked on a flat ground. The board surface must not touch the ground. The film face plywood should be kept well ventilated, prevented from sun and rain, and checked regularly.
