Types, characteristics, and selection of home decoration boards

A lot of panel materials must be used in home decoration. The quality of these panel materials and the degree of environmental protection will directly affect the effect of the whole home after decoration, and also affect the health of the owner. So the purchase of plate and home decoration and health are related, then let's look at the characteristics of the type of plate in home decoration and purchase.
1, solid wood
A solid board is a wood board made from intact wood. These plates are durable, natural grain, environmental protection, is the best choice in decoration. But because of the high cost of this kind of plate, the construction process requirements are high, it is not used much in the decoration.
Advantages: simple processing technology, good nail holding force.
Disadvantages: Because of a variety of miscellaneous wood combined together, the density difference is larger, easy to produce deformation; High water content; High formaldehyde content; Cannot be used directly, must do post-processing.
Usage: The commonly used processing method is to manually paste single-layer veneer or brush mixed oil, and paint varnish on the back. If both sides are pasted veneer, the cost is twice as high.
Environmental testing standards: formaldehyde emission per cubic meter of the plate should be less than or equal to 150 mg.
Solid wood is consolidated into wood
Solid wood is a solid wood board made of small pieces of solid wood splicing, splicing is generally made of sawtooth, and then adhesive, so it is also called tooth joint. Solid wood is not solid wood environmental protection, but the stability is much higher than solid wood, and the price is much cheaper than solid wood, so it is used more and more in furniture production and home decoration. At present, the stair pedal, high-end wardrobe and other aspects are used more. The stair pedal is generally made of solid wood such as ash willow or tussah, the cabinet body is generally made of pine, and the solid wood compound door is generally made of relatively cheap solid wood as the base material.
2. Plywood
Plywood, commonly known as fine core board, is made of three or more layers of veneer or sheet glue. It is commonly used for hand-made furniture. Generally divided into 3 cm plate, 5 cm plate, 9 cm plate, 12 cm plate, 15 cm plate and 18 cm plate six specifications (1 cm is 1mm).
veneer
Decorative panels are commonly known as panels. Is the solid wood precision planing cut into a thickness of 0.2mm or so thin veneer, plywood as the base material, through the adhesive process made into a single decorative decorative plate, the thickness is generally 3mm. Decorative panel is a kind of advanced decoration material which is different from mixed oil at present.
3. Joinery board
Joinery board commonly known as large core board. The large core board is made of two boards glued together in the middle. The vertical strength (differentiated by core trend) is poor, but the transverse strength is high. Large core board is widely used in home decoration. Its overall performance and environmental protection are good. It is an excellent board second only to solid wood.
Many consumers choose large core board, one look at the weight, two look at the price. In fact, the heavier the large core board, the worse its quality. Because the greater the weight, the more it indicates that the board used mixed wood, or the board inside the higher water content. A large core board made of miscellaneous wood may not be able to be nailed at all, so it cannot be used.
In addition, the price is very low, the quality of the large core board will be very poor. Either the gap is too big or substandard wood is used. So in the choice, it is best to choose about 100 yuan a large core board or even more expensive. This price of large core board, its quality is relatively stable.
The selection of large core board is to look at the appearance: one side of the large core board must be a whole panel, the other side is only allowed to have a seam. In addition, the surface of the large core plate must be dry and clean.
When choosing a large core board, be sure to cut a corner and check the quality inside. The gap of small wooden strips spliced inside should not exceed 5mm. Wood with bark, cavities and knots should not be used. Good quality of the large core board, among which the small wooden strips, there are serrated tenon joint.
In use, the large core board can only be "open" along the long side, can not be sawed across the use. In addition, try not to paint the large core board directly, to paste a layer of plywood on the outside as a panel, otherwise it is easy to appear paint bubbles and other problems.
4. Particle board
Particleboard is made of wood scraps as the main raw material, and then infiltrated with glue and additives. According to the pressing method can be divided into extruded particleboard, flat pressure particleboard two categories. The main advantage of this type of plate is that it is extremely cheap. Its disadvantages are also obvious: poor strength, environmental protection performance is not easy to control.
E1 grade particleboard, originated in Europe, is widely used in developed countries in the world. E1 grade particleboard is a composite board made of wood chips processed by high temperature and high pressure. Special formula is added to the substrate in the production process to improve the moisture-proof performance of the substrate, and green is injected to distinguish it. Moisture-proof board is not easy to deformation, moisture-proof, environmental protection, kitchen cabinet is the most ideal plate. In Europe mandatory kitchen, bathroom use board must all use E1 moisture-proof board.
Advantages: The interior is a granular cross structure, so the nail holding force is good, the lateral bearing force is good, and the cost is lower than the medium density board, although the formaldehyde content is higher than the medium density board, but it is much lower than the large core board; The price is relatively cheap (60 to 160 yuan per sheet depending on the difference between imported and domestic finishes and thickness).
Disadvantages: Because the method is easy, the quality is very different, it is not easy to distinguish, the flexural and tensile properties are poor, the density is loose and easy to loosen.
Usage: The surface is often pressed on both sides of the surface with trihydrogen ammonia, and the appearance of the medium density board is the same after edge sealing treatment; Need to cut with precision equipment, but also use special connector assembly, detachable.
Environmental testing standards: formaldehyde emission per cubic meter of the plate should be less than or equal to 40 mg.
5. Fireproof board
Fireproof board is a decorative board made of siliceous material or calcareous material as the main raw material. It is a new kind of material which is used more and more at present. The construction of fireproof board has relatively high requirements for pasting glue, and the thickness of fireproof board is generally 0.8mm, 1mm and 1.2mm.
6. Melamine board
Melamine board is a board made of hot pressing with different colors or textures of paper soaked in melamine resin adhesive, then dried to a certain degree of curing, and then paved on the surface of particleboard, medium density fiberboard or hard fiberboard. Because of the rich color and texture of melamine board, beautiful and durable, so many panel furniture uses melamine board as the main board.
7, Australian pine board
Australian pine board produced in Australia, is a kind of high precision wood board, with a good balanced structure. It belongs to the density board category. It is an ideal wood board product made from the combination of natural and artificial creativity. It has a good balanced structure, smooth edges and excellent mechanical properties. Its strength and stability are widely used in Australian overseas furniture, and its smooth surface makes it easy to oil dye, clean, tint, spray dye and various forms of inlay and covering.
Australian pine board has the advantages of natural fiber, it has the strength and characteristics of wood, but also avoid wood knot and other defects (cracking, water absorption expansion rate, etc.).
Aosong board has excellent homogenous structure and unique strength and stability, which makes Aosong board a kind of high quality board. Its smooth surface is easy to process into beautiful products. The sheet can be bent into curves and has high internal bonding strength, making the board easy to glue, nail, screw and fix.
8. Density board
Density board is also called fiberboard. It is an artificial board made of wood fiber or other plant fiber. According to its density, it is divided into high density board, medium density board and low density board. Density board is widely used in furniture because it is soft and impact resistant and easy to be reprocessed.
The main disadvantage of the density board process is that it is swollen, and it is almost hopeless when it meets water. Another disadvantage is poor bending performance, can not be used for heavy stress projects.
Advantages: excellent physical performance, uniform material, no dehydration problem, will not be affected by moisture deformation; The surface of the polyurethane finish has the characteristics of moisture-proof, anti-corrosion, wear resistance, high temperature resistance, no need for post-treatment, low formaldehyde content.
Disadvantages: high processing precision and technology requirements (because of high density, must be cut with precision saw); Poor nail holding force; Not in the decoration site processing; High cost (according to the difference between imported and domestic veneer and thickness, each price from 80 yuan to 200 yuan).
Usage: With large equipment double-sided at the same time hot pressing tri-hydrogen surface in the medium density board molding, tightly attached to the medium density board substrate surface, there are a variety of colors to choose from, must be processed with professional precision equipment, the use of special connectors fixed, can be arbitrarily disassembled and assembled, combination. The formaldehyde emission per cubic meter of the plate should be less than or equal to 30 mg.
