When it comes to plywood, it is estimated that professionals do not have a special understanding of it, in fact, plywood is often used in our home decoration, generally used in custom furniture, is the main material of furniture.
It is also a construction material used for decoration, which will be installed and used in the early stages of construction. Although this type of plate is widely used, there are also many consumers who are confused by its different specifications, so next we will understand what is plywood? What are the specifications of plywood?
what is plywood?
In fact, plywood is a new type of wood-based board, which is composed of the table board and the inner board, and is generally symmetrically configured on both sides of the central layer or the board core, and then the wood adhesive is used to bond these plate-like materials into a whole, which can help us save wood resources, so it is also a very fashionable and very environmentally friendly rational use. Generally, plywood will have more than three layers, and the odd layer will be more, and the physical and mechanical properties of the board will be greatly improved after modern fine processing. The increase in plywood specifications also makes it more suitable for furniture manufacturing and construction, and it has gradually occupied a dominant position in other industries, such as shipbuilding and aircraft.
what are the specifications of plywood?
The length and width of plywood will vary slightly because the manufacturer is different, but generally there will be 1220×2440mm, 1220×1830mm, 915×1830mm, 915×2135mm of these specifications, according to our needs to use, you can also choose different length and width plywood to use. The thickness of the plywood is actually determined by the number of layers, in addition to the table board, the more layers of the inner board configuration, the thicker its thickness will be, but only from the thickness to the plywood classification, can be divided into 3, 5, 9, 12, 15 and 18 mm of these categories of specifications. Therefore, there is no fixed length and width specification for plywood.
What are the categories of plywood?
1, a class of plywood
This kind of plywood has a very long life, has the characteristics of weather resistance and boiling water resistance, and is generally suitable for ships, so its price is also very expensive.
2, two kinds of plywood
This kind of plywood can be impregnated in cold water and hot water for a short time, and it is also a water-resistant plywood, which has poor performance compared with a class of plywood.
3, three types of plywood
This kind of plywood is generally more resistant to moisture, but can not be soaked in water, and is more suitable for furniture and general construction.
4, four types of plywood
This kind of plywood is not moisture-proof or water-resistant, so its price will be cheaper, and it can be used without special requirements.
