1. Classification of wooden boards
1. According to material classification, it can be divided into two categories: solid wooden boards and artificial boards. At present, except for the solid wood boards used for floors and door leaves, generally the boards we use are artificially processed artificial boards.
2. According to the molding classification, it can be divided into: solid board, plywood, fiber board, decorative panel, fireproof board, etc.
2. Types of wooden boards
1. Solid wooden boards.
As the name suggests, solid wood boards are wood boards made of complete wood. These boards are durable and have natural texture, making them the best choice for decoration. However, due to the high cost and high construction technology requirements of this type of panels, they are not used much in decoration. Solid wood boards are generally classified according to the actual name of the board, and there is no unified standard specification.
2. Solid wood flooring
Solid wood flooring is the most common ground decoration material used in decoration in recent years. It is a very significant symbol of the improvement of the quality of life of Chinese families. Solid wood flooring has the advantages of solid wood boards, but because it is produced by industrial production lines in factories and has uniform specifications, it is easy to construct and even faster than other board constructions. However, its disadvantage is that it requires relatively high craftsmanship. If the builder's skills are not good enough, it will often cause a series of problems, such as arching, deformation, etc.
The name of solid wood flooring consists of the name of the wood and the name of the edge treatment. The edge joint processing is mainly divided into three types: flat mouth (no tongue and groove), tongue and groove, and double tongue and groove. Flat flooring is an obsolete product. However, double tongue and groove flooring cannot yet become popular due to immature technology. Most of the floors currently laid are single tongue and groove floors. Generally speaking, the tongue and groove floor also refers to the single tongue and groove floor.
Solid wood flooring can also be divided into two types: painted board and plain board according to the treatment of the paint surface. Painted boards refer to those that have been topcoated before leaving the factory, while plain boards refer to those that have not yet been painted. The construction period of paint board is short, but the surface smoothness is not as good as that of plain board, and there will be slight unevenness. The construction period of plain board is slow, generally one to two times longer than that of painted board, but the surface is smooth.
3. Composite flooring
Composite wood flooring, also called laminate flooring, is often named by some companies for different purposes, such as super-strong wood flooring. , diamond-shaped wood flooring, etc., no matter how complicated and different their names are, these boards are all composite floors. Just as we call a helicopter a helicopter rather than a helicopter, these boards do not use wood, so it is unreasonable to use the term composite wood flooring. The appropriate name is laminate flooring. The national standard name for this type of flooring is: impregnated paper laminated wood flooring.
Laminate flooring is generally composed of four layers of materials: the bottom layer, the base material layer, the decorative layer and the wear-resistant layer. The number of revolutions of the wear-resistant layer determines the life of the composite floor.
1) Bottom layer: made of polyester material, which is moisture-proof.
2) Base layer: Generally made of density board, depending on the density of the density board, it is also divided into low density board, medium density board and high density board.
3) Decorative layer: Special paper printed with specific patterns (mainly simulating real textures) is soaked in melamine solution, chemically treated, and heated by melamine. The final chemical properties are stable and no chemical reactions occur, making this paper a beautiful and durable decorative layer.
4) Wear-resistant layer: It is a wear-resistant agent consisting of a layer of aluminum oxide evenly pressed on the surface of the laminate floor. The content of aluminum oxide and the thickness of the film determine the number of wear-resistant revolutions. The rotation speed of a wear-resistant layer containing about 30 grams of aluminum oxide per square meter is about 4,000 rotations, the wear-resistant rotation speed of a wear-resistant layer with a content of 38 grams is about 5,000 rotations, and the wear-resistant rotation speed of a wear-resistant layer with a content of 44 grams should be 9,000 rotations. Left and right, the greater the content and film thickness, the higher the number of revolutions, and the more wear-resistant it is.
The disadvantage of composite flooring is that when it is laid over a large area, there will be overall arching and deformation. Because it is made of composite materials, the edges and corners between boards are easily broken or worn.
4. Plywood
Plywood, also known as plywood, is commonly known as thin core board in the industry. It is made of three or more layers of one millimeter thick veneers or thin sheets glued together and hot pressed.
It is currently the most commonly used material for hand-made furniture. Plywood is generally divided into six specifications: 3cm, 5cm, 9cm, 12cm, 15cm and 18cm (1cm is 1mm).
5. Decorative panels
Decorative panels, commonly known as panels. It is a decorative board with a single-sided decorative effect made by precisely slicing solid wood boards into thin veneers with a thickness of about 0.2mm, using plywood as the base material, and using an adhesive process. It is a special form of plywood with a thickness of 3 cm. Decorative panels are an advanced decoration material that is different from the current mixed oil method.
6. Blockboard
Blockboard is commonly known as large core board in the industry. Large core board is made of two pieces of veneer glued and spliced ??together. The price of large core boards is cheaper than that of thin core boards. Its vertical bending strength (divided by the direction of the core material) is poor, but its transverse bending strength is higher.
7. Particleboard
Particleboard is a thin board made of wood chips as the main raw material, then added with glue and additives and pressed. According to the pressing method, it can be divided into two categories: extruded particleboard and flat pressed particleboard. The main advantage of this type of board is that it is extremely cheap. Its shortcomings are also obvious: extremely poor strength. It is generally not suitable for making larger furniture or furniture with mechanical requirements.
8. Density board
Density board, also called fiberboard. It is an artificial board made of wood fiber or other plant fibers as raw materials and applied with urea-formaldehyde resin or other applicable adhesives. According to its density, it is divided into high density board, medium density board and low density board. Because density board is soft and impact-resistant, it is also easy to reprocess. In foreign countries, density board is a good material for making furniture. However, because the national standard for height boards is several times lower than the international standard, the quality of density boards in our country needs to be improved.
9. Fireproof board
Fireproof board is made of siliceous material or calcium material as the main raw material, and a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives Mixed, autoclaved decorative panels. It is a new type of material that is increasingly used at present, and its use is not only due to fire protection. The construction of fireproof boards requires relatively high glue, and the price of better quality fireproof boards is more expensive than decorative panels. The thickness of fireproof board is generally 0.8mm, 1mm and 1.2mm.
10. Melamine board
Melamine board, the full name is melamine impregnated adhesive film paper faced artificial board. It is a decorative board made by soaking paper with different colors or textures in melamine resin adhesive, drying it to a certain degree of solidification, paving it on the surface of particleboard, density fiberboard or hardboard, and hot pressing it. Melamine board is a wall decoration material. At present, some people use melamine boards to fake composite floors for floor decoration, which is inappropriate
