According to the material classification, the plates can be divided into solid wood panels and wood-based panels . According to the molding classification, they can be divided into solid panels, plywood, fiberboard , decorative panels, fireproof panels and so on.
1, solid wood board
As the name suggests, it is to use solid wood panels made from wood plate full of wood. These plates are sturdy and durable, and the texture is natural. However, due to the high cost of such panels and the high construction process requirements, there are not many uses in the decoration. Solid wood boards are generally classified according to the physical name of the board, and there is no uniform standard specification. At present, in addition to the use of solid wood panels for floors and door fans, the panels we use are generally artificially machined panels.
2, splint
The splint, also known as plywood , is commonly known as a thin core board. It is made of three or more layers of one millimeter thick veneer or sheet adhesive. It is the most commonly used material for hand-made furniture . The splint is generally divided into three specifications of 3 PCT, 5 PCT, 9 PCT, 12 PCT, 15 PCT and 18 PCT (1 PCT is 1 mm).
3, decorative panel
Decorative panel, commonly known as the panel. The wood board is sliced to a precise thickness of about 0.2mm micro skin veneer to plywood for the substrate, making the process through the adhesive from one surface of the decorative sheet material having a decorative effect. It is a special way of splinting and has a thickness of 3 centimeters.
4, blockboard
Blockboard, commonly known as large core board. The large core board is made up of two sheets of veneers bonded together in the middle. The price of the large core board is cheaper than that of the thin core board, and the vertical direction (differentiated by the core material direction) is inferior in bending strength, but the lateral bending strength is high.
5, particle board
Particleboard is a thin sheet made of wood scrap as the main raw material, then added with glue, and the additive is pressed. According to the pressing method, it can be divided into two types: extruded particle board and flat particle board. The main advantage of this type of sheet is that it is extremely cheap. The disadvantages are also obvious: the strength is extremely poor. It is generally not suitable for making larger or mechanically demanding furniture.
6, MDF
MDF, also known as fiberboard. It is made of wood fiber or other plant fiber, and the artificial board made of urea-formaldehyde resin or other suitable adhesive is divided into high-density board , medium-density board and low-density board according to its density. MDF is also easy to rework due to its soft and impact resistant properties. In foreign countries, MDF is a good material for making furniture, but because the national standards for height plates are several times lower than international standards, the quality of MDF use in China needs to be improved.
7, fire board
The fireproof board is a decorative board made of a silicon material or a calcium material as a main raw material, mixed with a certain proportion of fiber materials, lightweight aggregates, binders and chemical additives, and subjected to autoclaving technology. It is a new type of material that is being used more and more, and its use is not only due to fire prevention. The construction of fireproof board has higher requirements for sticking glue, and the price of fireproof board with better quality is more expensive than decorative panel. The thickness of the fireproof board is generally 0.8 mm, 1 mm and 1.2 mm.
8, melamine board
The melamine board, the full name is a melamine impregnated film paper veneer wood-based panel, is a wall decoration material. The manufacturing process is to put paper with different colors or textures into a melamine resin adhesive, and then dry to a certain degree of solidification, and lay it on the surface of particleboard, medium density fiberboard or hard fiberboard, and hot pressed. Decorative plates.
Office filing cabinets are made of sheet metal and wood. The drawers usually use a drawer slide to facilitate opening the drawer which includes an "outstop" to prevent the drawer from being pulled completely out of the cabinet. To open a drawer on most metal filing cabinets, a small sliding mechanism known as a "thumblatch" must be pressed to release and open the drawer. Each drawer has a handle to grip and pull the drawer with. On the front face of each drawer, there is usually a label holder to allow the user to identify the contents of the drawer. Many file cabinets incorporate a keyed lock to prevent unauthorized access to the documents being stored. There are two types of locks. A "cam lock" is activated with a key that rotates the lock. A "plunger lock" is opened with a key but can be closed by merely depressing the body of the lock. The plunger lock allows a user to quickly close and lock several cabinets in a short amount of time. Some file cabinets have a metal plate or wire structure at the back of each drawer which is known as a follower block. The follower block can be adjusted forward to reduce the length of the drawer so that the file folders contained within remain upright and at the front of the drawer for easier access.
