What types of boards are there for making furniture, and what are the characteristics of each? How much do you know about the types of boards? The editor of Tubatu will summarize them for you below:
1. Woodworking board (commonly known as large core board)
Woodworking board (commonly known as large core board) is a plywood with a solid wood core. Its vertical bending strength (divided by the direction of the core board) is poor, but The transverse bending strength is high. Most of the boards on the market now are solid, glued, double-sided sanded, and five-layer blockboards, which are one of the most commonly used boards in decoration.
Personal opinion: In fact, the environmental protection factor of better quality woodworking boards can be guaranteed, but the cost is also higher, and with multiple processes such as later painting, it will be more or less of turning an environmentally friendly product into less environmentally friendly. Under normal circumstances, in a furniture room made of wood panels, it must be ventilated and ventilated. It is best to leave it vacant for a few months before moving in.
2. Particleboard
Particleboard is made by cutting various branches, small diameter wood, fast-growing wood, sawdust, etc. into pieces of certain specifications. After drying, they are mixed with glue. A kind of artificial board made by pressing hardener, waterproofing agent, etc. under a certain temperature and pressure. Because its cross section is similar to a honeycomb, it is called particleboard.
Adding a certain amount of "moisture-proof factor" or "moisture-proof agent" and other raw materials inside the particleboard becomes what people usually call moisture-proof particleboard, or moisture-proof board for short. It has a certain moisture-proof effect because the particleboard itself has It has a certain degree of moisture resistance and has a small expansion coefficient after absorbing water. It is widely used in cabinets, bathroom cabinets and other environments. However, in reality, it has become a tool for many inferior particleboards to cover up internal impurities. Adding green dye inside the particleboard forms what is currently called a green-based particleboard in the market. Many manufacturers use it to mislead it into a green environmentally friendly board, but in fact there is no scientific basis. In fact, most of the particleboards of top brands at home and abroad are natural base materials.
3. Fiberboard
When some businesses say that they use high-density boards to make cabinets, you might as well weigh the weight of the boards per unit area according to the density standards above. See See whether it is a high-density board or sell it as a medium-density board as a high-density board. This practice may affect the interests of some businesses, but from the perspective of doing business with integrity, promoting yourself as a high-density board You won’t be afraid of customers verifying it.
4. Solid wood finger-jointed board
Finger-jointed board, also known as integrated board, integrated lumber, finger-jointed lumber, is a small piece of solid wood that has been deeply processed to look like "fingers". The boards are spliced ??together like "heads". Because the sawtooth joints between the boards are similar to the interlocking fingers of two hands, they are called finger-jointed boards. Since the log strips are cross-bonded, the bonding structure itself has a certain bonding force, and since there is no need to glue the surface panels up and down, the amount of glue used is extremely small.
In the past, we used camphor wood finger-jointed boards as cabinet backboards, and they were even sold as a selling point. However, some cracks and deformations did occur during later use. , so the use of camphor wood as the back panel of the cabinet was later cancelled. I would like to remind customers who want to use finger-jointed boards to make cabinet furniture that they must carefully choose the boards and negotiate with the manufacturer about possible cracking, deformation, etc. in the future. Whether as a business or an individual, It's all about talking first and then not messing up. If we communicate well, there will be less trouble later.
5. Particle board
The so-called solid wood particle board is actually a board produced by the particle board process. It is a kind of particle board and belongs to the homogeneous particle board.
The scientific name of homogeneous particle board is oriented strand board. It is made of small diameter wood, thinning wood, wood core, board skin, branch wood, etc. and is processed by special equipment into a length of 40mm, 70mm, and a width of 5mm. It is a kind of artificial board that is formed by hot pressing of 20mm, 0.3mm, 0.7mm shavings. After drying, gluing and special equipment, the surface core layer shavings are laid in a criss-cross direction. After Daya homogeneous particleboard flakes are dried through an advanced single-channel dryer, the expansion coefficient is small and the moisture-proof performance is very good. The flakes are paved layer by layer in a directional manner, so its internal texture is uniform and better than Ordinary particle board and powdery density board have stronger nail-holding strength, bending resistance and stability.
6. Multi-layer solid wood board
Multi-layer solid wood board is based on multi-layer plywood arranged in a criss-cross pattern, and the surface is made of high-quality solid wood veneer or technical wood as the fabric. It is made through several processes such as pressing, hot pressing, sanding and curing. Because multi-layer solid wood boards are not easily deformed and have excellent properties of regulating indoor temperature and humidity, and the surface solid wood veneer materials have the texture and feel of natural real wood, they are more selective. Therefore, it is highly favored by consumers.
Multi-layer solid wood boards have good structural stability and are not easily deformed. Due to vertical and horizontal gluing, high temperature and high pressure, the deformation defects of solid wood boards are solved from the aspect of internal stress. Self-made high-quality environmentally friendly glue is used in the production process to ensure that the formaldehyde release limit of the product meets national standards and is green and environmentally friendly.
Density board
Density board (also known as "fiber board") is made of woody raw materials such as trunk wood, branch wood or other plant fibers as raw materials, which are heated and ground into powder. ), sizing (urea-formaldehyde resin or other suitable adhesives), drying, paving and hot pressing.
Advantages
Various veneers, tape films, decorative panels, light metal sheets and other materials can be glued on the surface of the density board; various coatings and paints can also be applied On density boards, the effect is very beautiful
Hard density boards can also be made into sound-absorbing boards after punching and drilling. They have smooth and flat surfaces, fine materials, stable performance, strong edges, and are easy to shape. Avoids problems such as decay and insect infestation
Excellent physical properties, good nail holding power, uniform material, no dehydration problem
Disadvantages
Not moisture-proof, When exposed to water, it will swell, and the load-bearing deformation will be large for a long time
Moisture-proof board
Moisture-proof board is to add a certain proportion of moisture-proof particles to the particle board base material, which can cause the board to swell when exposed to water. The degree is greatly reduced.
Advantages
In addition to the advantages of particleboard, another outstanding advantage is moisture resistance. However, it should be noted that moisture-proof board and ordinary particle board have the same expansion rate when soaked in water. The so-called moisture-proof board only has an effect on the moisture in the air
Disadvantages
All particle board All moisture-proof boards have shortcomings
Large core board
Large core board (also known as "blockboard") is made of two veneers glued together and spliced ??together. The wooden boards are made of high-quality natural wooden boards that are heat-treated (i.e., dried in a drying room) and then processed into wooden strips of a certain specification. The spliced ??wooden boards are then spliced ??by two layers of high-quality veneers on both sides. It is made after being glued by a cold or hot press. The total thickness of the two-sided glued veneer of the large core board shall not be less than 3mm. The width and length of all types of large core boards shall not exceed 5mm within the nominal width. No larger than 20mm
Advantages
Good screw holding power, high strength, strong quality, sound absorption, heat insulation, etc., and the moisture content is not high, between 10% and 13%. It is easy to process
The machine-assembled plates are subject to a large extrusion force, the gaps are extremely small, the splicing is smooth, the load-bearing force is even, and the structure is compact and not easy to deform after long-term use
Disadvantages
Poor moisture-proof performance
Manually assembled wooden strips are manually inserted into the plywood. The extrusion force on the wooden strips is small, the splicing is uneven, the gaps are large, and the nails are held. It has poor strength and cannot be sawed and processed. It is only suitable for partial decoration sub-projects, such as cushioning rough boards for solid wood floors.
Fir boards are made of short pieces of wood. It is a large-format thick board synthesized by finger-tenon jointing and jointing. It generally uses high-quality wood (mostly fir, so it is commonly known as fir board) as the base material, and is degreased, dried, finger-jointed, and sanded at high temperatures. Made with light and other techniques.
Advantages
After high-temperature degreasing treatment, it is assembled with tenons and tenons; it is durable, insect-free and non-deformable, and also exudes a light woody fragrance
It is an original natural board with clear wood grain, natural and generous, and a natural and simple feeling of returning to nature; the amount of glue used is only seven-tenths of that of woodworking boards, and it is highly environmentally friendly
The surface has been sanded The thickness is fixed and smooth, and there is no need to veneer the surface when making the wardrobe, which saves labor and materials, and is economical and economical
Disadvantages
The moisture content of poor-quality fir boards is not up to standard. It is easy to deform and will crack over time
Australian pine board
Australian pine board (also called "oriented structural strand board"), Australian pine board is a medium density board imported from Australia .
Advantages
It has high internal bonding strength. The surface of each board has been sanded with high precision to ensure a first-class finish. The smooth surface makes it easy to oil, stain, and stain. Cleaning, coloring, spray dyeing and various forms of inlaying and covering
Not only does the surface of the board have the strength and various advantages of natural wood, but it also avoids the defects of natural wood. It is an upgraded product of plywood< /p>
It has a well-balanced structure, with smooth edges and excellent mechanical properties
Disadvantages
It does not eat nails, it has a good nail-holding effect on screws , but the nail-holding performance for hammer-drilled nails is average
European pine board
European pine board (also called "oriented strand board") is mainly made of fast-growing wood and thinning wood ( Such as pine, poplar, etc.) as raw materials, processed through special equipment into 40-100mm long, 5-20mm wide, 0.3-0.7mm thick shavings, dried, screened, glued, directional paved, continuous hot-pressed forming, etc. It is a new type of plate made from Europe and developed rapidly internationally in the 1970s and 1980s [3].
Advantages
Low formaldehyde release, strong and durable, the furniture is light in weight and has better flatness
The interior is a directional structure with no joints, no gaps, Cracks, good overall uniformity, and extremely high internal strength, so both the center and the edges have super nail-holding capabilities that ordinary boards cannot match
Disadvantages
Like Australian pine boards, European pine board does not eat nails. It has a good nail-holding effect on screws, but its performance on holding large nails driven in by a hammer is average
