What is plywood?
plywood is a board made of splicing wood and applying glue. The surface of the veneer boards is flat and easy to process.
Plywood is a three-layer or multi-layer board-like material made of wood pieces that are peeled into veneer or sliced into veneer from wood, and then glued with adhesive. Usually, odd-numbered veneers are used and adjacent layers of veneers are used. The fiber direction is perpendicular to each other and glued together. The sheet product has a flat shape, a large width-to-thickness ratio, and a large surface area per unit volume.
What is MDF board?
MDF board is generally made by crushing plant fibers and other wood fibers into powder and applying adhesive. The board has the characteristics of good nail holding power and high strength. Due to the price advantage of the board in the market, it has become the current furniture Plates commonly used in the market.
MDF board, also known as fiberboard, is a man-made board made of wood fiber or other vegetable fiber as raw material and applied with phenolic resin or other suitable adhesives. Adhesives can be applied during the manufacturing process. density fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, and not easy to crack, and has a wide range of uses. The shortcoming of 4x8 fiberboard is that the back surface has a net pattern, which causes the surface area of the two sides of the board to be different, and the board warps and deforms due to the difference in expansion force after moisture absorption. The hard board has a hard surface and poor water resistance.
The difference between plywood and MDF board
1. Different production processes
Plywood is a three-layer or multi-layer board-like material made of wood pieces that are peeled into veneer or sliced into thin wood, and then glued with adhesive; MDF board is to separate wood or other plants into fibers, using fibers between the interweaving and its own inherent bonding material, or applying adhesive, under the conditions of heating or pressure made the board.
2. Different product categories
Plywood is divided into four categories according to its bonding strength: one is weather resistant plywood and boiling water resistant plywood. This type of plywood is durable, resistant to boiling or steam treatment, and can be used outdoors; the second type of plywood is water resistant plywood, which can be immersed in cold water and short-term hot water; the third type of plywood is moisture resistant plywood, which can be short in cold water time immersion, suitable for indoor use at room temperature. Used for furniture and general construction purposes; the four types of plywood are non-moisture-resistant plywood, which is used indoors under normal conditions. The general-purpose plywood materials include beech, basswood, ash, birch, elm, poplar, etc.
MDF boards are divided into three categories according to their density: low density boards, medium density boards and high density boards.
3. Classification of performance and purpose
Plywood is mainly used for house construction, interior wall decoration and door panels, etc. It has the characteristics of light weight and good flexibility on the outer surface of the shape, such as arc-shaped places; MDF is mainly used for furniture manufacturing, building materials, vehicle and ship manufacturing, and packaging materials and other fields. The surface of plywood is not as smooth and flat as that of MDF. Compared with MDF, the material moisture content of plywood is more stable, and compared with MDF, plywood has better moisture resistance, and nail-holding plywood is stronger than MDF.
Which is better, MDF or plywood?
Take the wardrobe as an example. Generally, when you buy a wardrobe in a wardrobe store, they will use MDF for you; plywood, people usually not use it to make a wardrobe.
