First, blockboard

1. What is the concept of blockboard?

Block board (known as large core board, wood board) is a plywood with solid wood core. Its vertical direction (differentiated by core

 sheet) is resistant to bending and pressure, but the transverse

 bending strength is high. Most of the market is now solid, glued,

 double-sided sanding, five-layer block board, size specification is 1220 mm × 2440 mm.

2. What are the characteristics of Blockboard?

The blockboard has good clamping force and high strength, and has the characteristics of firmness, sound absorption and heat insulation, and the water content is not high. Between 10% and 13%, the processing is simple and the most widely used. Blockboard is more stable than solid wood. However, if you are afraid of moisture, you should avoid using it in the kitchen. The processing technology of blockboard is divided into two types: hand-stitching is to manually insert the wooden strip into the panel. The strip is subjected to poor pressing force and cannot be cut and processed, and it is only suitable for partial decoration. Such as the solid wood floor cushion board and so on. The sheet of the machine is subjected to a large pressing force, the gap is extremely small, the splicing is flat, the bearing capacity is uniform, and the long-term use is not easily deformed. The price of blockboard is between 70-140 yuan, and the difference is between 40-60 yuan. The core of the blockboard has many kinds of materials, such as poplar, birch and pine. Among them, poplar and birch are the best, the texture is dense, the wood is not soft and not hard, the nail holding power is strong, and it is not easy to be deformed. The texture of Paulownia is soft, the water absorption is large, and it is not easy to dry. After the long-term use of water is evaporated, the sheet is easy to dry and deform. The hard wood is hard, not easy to press, the splicing structure is not good, the nail holding power is not bad, and the deformation coefficient is also large.

3. What is the purpose of the blockboard?

Furniture, doors and windows and sets, partitions, false walls, heating covers, curtain boxes, etc.

4. How to choose the blockboard?

The surface of the blockboard should be flat, free from warping, deformation, and no blistering or dent. The core strips are evenly arranged, the gaps are small, and the core strips are free from decay, breakage, wormholes, and thrift. Some blockboards cut corners and the gap between solid wood strips is large. If the nail is nailed at the gap, there is substantially no nail holding force.

Consumers can look at the sun when they choose, and the gap between the solid wood strips will be white. If the glue strength of the blockboard is not good, there will be a "beep" opening sound. If the large core board emits a fragrant wood smell, it means less formaldehyde is released. If the smell is pungent, it means that the amount of formaldehyde released is more. The quality of blockboard is very different and should be carefully checked when purchasing. First of all, see if the core material is dense, whether there are obvious seams and decaying wood strips, whether there are obvious seams and decaying wood strips, and there may be eggs in the decaying wood strips, which may cause insects in the future. Look at the phenomenon of whether there is no glue or putty around, this phenomenon is generally to compensate for internal cracks or voids. Then tap the surface of the board with a sharp-nosed instrument to hear if the sound is very different. If the sound changes, there is a hole inside the board. These phenomena will weaken the overall bearing capacity of the board, and the uneven long-term stress will cause the sheet structure to be distorted and deformed, which will affect the appearance and use effect.

Second, Melamine faced plywood

1, The concept of plywood:Melamine plywood is made of three or more layers of a solid wood veneer or thin-sheet adhesive hot pressing, common three plywood, five plywood, nine plywood and twelve plywood (commonly known as plywood, five cents Board, nine PCT board, twelve PCT board). Plywood

2. Characteristics of plywood: good structural strength and good stability. The plywood has a large amount of glue, and it must be edge-sealed during construction to reduce pollution.

3. Use of plywood: Plywood is mainly used for various wood products such as the bottom sheet of decorative panel and the back panel of panel furniture. Plywood

4, selection of melamine faced plywood: Select the plywood mainly depends on its formaldehyde emission and bonding strength. If the gluing strength of the plywood is not good, it is easy to fall apart. When selecting, pay attention to whether the nominal thickness of the plywood matches the actual thickness.

The following points should be noted when selecting plywood:

(1) Plywood has the difference between front and back. When selecting, the plywood should have a clear wood grain, a smooth and smooth front surface, and no roughness.

(2) Plywood should not be damaged, bruised, bruised, shackles and other defects.

    (3) Glue full board without degumming.

(4) Some plywood is made by sticking two veneers of different textures together, so it is necessary to pay attention to the sheet joints in the selection, there should be no unevenness.

(5) When selecting plywood, you should pay attention to the selection of non-dispersed plywood. If the sound is brittle when the hands are knocked on all parts of the plywood, the quality is proved to be good. If the sound is boring, it means that the plywood has been discolored.

Third, Decorative panel

1. The concept of decorative panel: decorative veneer veneer plywood (decorative panel, veneer) is a thin veneer with a thickness of 0.2 mm or more, which is made of plywood as a substrate and glued. Decorative sheet with a single-sided decorative effect.

2, The characteristics of the decorative panel: decorative panels are generally used for clear oil decoration. The surface layer is thin and the board is a precious wood species with natural and gorgeous texture. The substrate is generally plywood and the performance is stable and reliable.

3, The use of decorative panels: decorative panels are commonly used in home decoration decoration materials.

4, The choice of decorative panels: there are unscrupulous merchants on the table level board to make a fuss, the surface panel is too thin, the thickness is only about 0.1. In order to prevent the color of the bottom sheet from being exposed, firstly paint a layer of the same color as the surface layer on the bottom sheet, and then attach the surface layer panel. Due to the poor adhesion of the paint to the glue, the surface panel has poor bonding strength and is easy to drum. When the consumer chooses, the blade can be used to scrape the surface layer. Where the excellent paint is scraped, most of the surface panel thickness is not up to standard.

After using the inferior decorative panel for a period of time, the surface will be bulged and cracked. Pay attention to the following points when purchasing decorative panels:

1 、Identify the difference between artificial veneer veneer and natural wood veneer veneer. The texture of the former is basically straight texture, and the texture pattern has rules. The latter is a natural wood pattern, and the natural variability of the texture pattern is relatively large and irregular.

2 、Decorative is better. The appearance of the decorative panel should have a good aesthetic, the material should be fine and even, the color is clear, and the wood grain is beautiful. The texture of the matching board and the parquet should be arranged according to a certain regularity, the natural color is similar, and the seam is almost parallel to the edge of the board.

 3、The surface should be free of visible defects. The surface of the selected decorative board should be smooth, free of burr grooves and planing marks. There should be no penetration phenomenon and surface contamination (such as local yellowing and blackening). Should choose the surface without cracks, cracks, no knots, skin, resin enamel and gum road. The natural warpage of the entire board should be as small as possible to avoid the phenomenon of sand seeping through the material caused by improper operation of the sanding process.

4、No glue phenomenon. It should be noted that there should be no bulging or delamination between the surface vene、er and the substrate and between the layers inside the substrate.

5、The 5-knife method is the most intuitive method to check the bonding strength. It is opened along the adhesive layer with a sharp flat blade. If the rubber layer is broken and the wood is not damaged, the bonding strength is poor.

6、To choose a sheet with low formaldehyde emission. When choosing, avoid decorative panels with a pungent odor.

7、 Choose a good product with a clear production company. Most of the products with clear factory name, factory address and trademark have good performance.
