Description of the Details of Film Faced Plywood
一、 What is film faced plywood?
Film faced plywood is an exterior plywood used in building and construction projects. It has special film coating on surface made with phenol melamine glue, which gives the plywood higher resistance to moisture, abrasion, chemical degradation and fungal attack compared to ordinary plywood.
二、 Introduction of Product

1.The high-strength plywood is an ideal material for formwork.
2. It performs longer in both humid and wet conditions and resists delaminating.
3.Weight less than steel plate, easy to model as requested.
4.Recycling to use many times.
1.Planking 2.Molding 3.Prepressing 4.Hot-pressing（115℃） 5. Deal surface 6. Sanding 7.Laminated with Hot-pressing 8.Sawing 9.Checking(one by one) 10.Printing(waterproof edge) 11.Inter package 12.Outer package
2) Two molding
1.Planking: The core board is laid by hand in the order of one layer with glue and one layer without glue. In general, even layer rubber plate
3.Prepressing: Press the plywood with mechanical pressure to allow the glue to work and preform the plywood.(16-17Pa,50 minutes)
4.Deal surface: Repair irregularities and gaps in plywood surfaces with small core panels.
5.Hot-press: The substrate enters the hot press. (135℃，15Pa about,50minutes)
7.Sanding: wait one day，dry board.
8.Sawing: Cut the plywood into specification sheets. The edge is coated with phenolic adhesive, which has better water resistance.
9.Sanding：Putty is mainly composed of WBP glue, talcum powder, scraping the surface of the uneven.
10.Laminated with the board and hot-pressing(135℃, 20Pa, 3-4 minutes)
11.QC: Check the quality and pick out the bad plywood
12.Printing: Waterproof paint apray.
14. Loading & Shipping
3)The difference between one molding and two molding?
The two molding of the film faced plywood is made by two heat presses and one sanding for better flatness.
Check quality, size, thickness, moisture etc.
With the development of high-rise buildings, the quantities of cast-in-place concrete structures increase day by day, which promotes the rapid development of formwork technology.Building formwork is an important tool for concrete structure construction.
Experts point out that in the cast-in-place concrete structure engineering, the formwork engineering generally accounts for 20% ~ 30% of the construction cost of the concrete structure engineering, 30% ~ 40% of the project labor, accounting for about 50% of the construction period.
The use of energy-saving and environment-friendly building materials is the mainstream of the development of the construction industry today. It is inevitable to make the most efficient use of resources and minimize the impact on the environment
