what is film faced plywood？
Film faced plywood is the wood along the direction of the annual ring cut into large sheets of veneer, after drying, gluing according to the principle of the adjacent veneer layer of wood grain direction perpendicular to each other, made of plywood. The number of veneer layers is odd, generally three to thirteen layers, common plywood, plywood, nine plywood, and thirteen plywood (commonly known as three board, five board, nine board, thirteen board). The outermost front board is called the panel, the opposite side is called the backplane, and the inner board is called the core board. Plywood can improve the utilization rate of wood and is a main way to save wood.
Plywood is one of the commonly used materials for construction and furniture, one of the three major panels of wood-based panels, and can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers is usually formed by gluing each other vertically according to the direction of adjacent layers of wood grain, and usually the surface plate and the inner plate are evenly arranged on both sides of the central layer or the core of the board. A slab made of gelled veneers crisscrossed in the direction of wood grain and pressed under heated or unheated conditions. The number of layers is usually odd, and a few have even numbers. The difference of physical and mechanical properties in vertical and horizontal directions is small.
The usual length and width specifications are: 1220×2440mm, and the thickness specifications are generally: 3, 5, 9, 12, 15, 18mm and so on. The main tree species are: camphor, willow press, poplar, eucalyptus and so on.
A kind of plywood is weather-resistant, boiling-water resistant plywood, from one to the other has the advantages of durability, high temperature resistance, steam treatment;
The second type of plywood is water-resistant plywood, which can be impregnated in cold water and short time hot water impregnation;
The three types of plywood are moisture resistant plywood, which can be impregnated in cold water for a short time and is suitable for use at room temperature. For furniture and general building purposes
Four types of plywood for moisture resistant plywood, in the indoor normal use, the general purpose plywood materials are beech, basswood, ash, birch, elm, poplar and so on.
Plywood for construction is mainly used in outdoor conditions, such as building decoration and concrete formwork, in the decoration project is mainly used in ceiling, wall skirt, floor lining board, cabinet, table and other furniture can be used to do plywood.
