Advantages and disadvantages of plywood

Cut a big tree into layers of 3mm-18mm thin boards, and the boards glued together are plywood.
The number of layers is usually 3-13 odd layers, which looks like a wafer cookie from the side.
It is also called "plywood" and "multilayer board" because it is glued layer by layer.
The so-called multi-layer solid wood board is actually plywood.
The name is named according to the number of layers of the clip, but this naming method is relatively rare, and the common one is only plywood.
It is very common to name according to the thickness. There are five -, seven - and nine-centimeter boards.

Performance and use of plywood

Moisture-proof and deformation resistant, and the bearing capacity is also good. Shaped furniture that is easy to process and difficult to manufacture and design has natural advantages.
Suitable for making cabinet body, cabinet door, back plate and bottom plate of furniture.
It is very suitable for near-water space, especially in humid areas in the south.
There is no beautiful wood grain on the surface of plywood.
If the cabinet door is made, it is not good to paint it directly, and other decoration should be added to the surface.
For example, use solid wood slices with good texture and thickness of about 2mm to paste on plywood.
Because of its strong toughness, durability and compressive strength, it is widely used in furniture, decoration, packaging, industry and other fields. From the advantages of plywood, plywood has durability and can be used for a long time; The second is its high strength. Plywood has high strength and can withstand great pressure; The third is its waterproof property. The plywood has good sealing property, which can prevent water from entering it; The fourth is the corrosion resistance of plywood: plywood is not easy to corrode and can resist the erosion of some chemicals.
Plywood has many advantages. Plywood with good quality and high performance-price ratio must be rushed by everyone. This may also be the reason why plywood is so popular in Zhenmu.
However, plywood also has some disadvantages. First of all, it cannot be directly exposed to sunlight or high temperature, so as not to cause discoloration or deformation of the surface. Secondly, plywood is easy to be affected by moisture. If it is not protected, it is easy to cause moisture cracks. In addition, improper use can also lead to wrinkles or cracks on the surface of plywood.

The manufacturing process of density board and particle board is very similar, but particle board is to break wood into particles, and fiberboard is to grind wood into powder. When pressing fiberboard with high-pressure spray glue, use more force and less force, and the density of the pressed board is different, so fiberboard is also called "density board".
Poor quality of low density board
High density board is too heavy and expensive
Only medium density board (MDF) is most suitable
The biggest disadvantage of performance and use of density board and particle board is that it is not moisture-proof and will bulge and deform when it sees moisture. It is not suitable for use in the bathroom where it is easy to get damp. In particular, we should pay special attention to the return from the south to the south. Poor bearing capacity, unable to make cabinet. It is only suitable for cabinet doors, or for non-load-bearing places, such as the back plate of the cabinet. The surface of fiberboard is smooth, especially suitable for secondary processing. It is no problem to paint or paste a pattern. If you like fancy, you can do cabinet door carving.

Particleboard (particle board/solid wood particle board) is made of various materials such as tree trunk, branches, branches, turf, straw, etc., which are planed into pieces and then pressed into porcelain solid board by high-pressure spray glue. Solid wood particle board is a particleboard with slightly better quality. Wood is used for shaving, and there is no leftovers such as turf and straw. The best quality solid wood particle board and shavings should not only be made of wood, but also the best wood from the trunk, not even the branches.
Particleboard is the most widely used board in the market. Because the mixed wood mixed with grass residue is used for the mixed chipboard with low cost, which can be produced by any small factory. When buying particleboard, you must choose a brand. The board itself can be better, and the edge can also be better (the edge can prevent formaldehyde diffusion and moisture).
Particleboard (particle board/solid wood particle board) performance-purpose good load-bearing, not easy to deform, and relatively balanced performance. The load-bearing cabinet body and cabinet door suitable for making furniture are the main plates of various customized furniture brands. In terms of moisture resistance, particleboard is similar to plywood, which can be used in kitchen cabinets. In terms of regional habits, southern cabinets prefer plywood, while northern cabinets prefer chipboard.
