Which large core board is best? What kind of board is the big core board?

Green Field or Universal two brands.

The large core board is a blockboard.

The large core board is the common name of blockboard, the middle is cut a piece of wood spliced together, but also to add a large amount of glue bonding, the upper and lower layers are veneer, that is, solid wood veneer, blockboard grip screw force is good, high strength, with the characteristics of firm, sound absorption, heat insulation, etc., and moisture content.

It is not high, between 10% and 13%, it is easy to process and is the most versatile.

The processing technology of blockboard is divided into two types: machine and hand. Hand-made is to manually inlay the wooden strips into the plywood, the extrusion force of the wooden strips is small, the splicing is uneven, the gap is large, the nail holding force is poor, and it can not be sawed and processed, and it is only suitable for partial decoration of the sub-project, such as the cushion of the solid wood floor.

wool boards, etc. <>

Selection of large core boards

The surface of a good blockboard is smooth, no warping, no deformation, no blistering, no depression, the core is arranged evenly and neatly, the gap is small, and the core has no decay, fracture, wormhole, knots, etc. Some blockboards cut corners, and the gaps in the solid wood strips are large, and if you nail in the gap, there is basically no nail holding power.

When choosing, you can look at the sun, and the gaps in the solid wood strips will be white. If the gluing strength of the blockboard is not good, there will be a "squeak" sound when one end of the blockboard is patted hard. If the large core board emits a fragrant wood odor, it indicates the amount of formaldehyde released.

Less; If the smell is pungent, it means that the formaldehyde is released.

I think you still have to come up with the original text before you can know the overall problem of this question. Here are some inconsequential encyclopedias!!

There is a simple way to identify the internal quality of the large core board: observe the large core board against the bright light, such as transparent white means that the wood strips are not spliced tightly enough; Listen to the sound when lifting it, and there is a creaking sound indicating that the gluing strength is not good; In the case of dry hand, lift one end of the large core board and weigh it, and the high-quality blockboard should have a sense of wholeness and heaviness; Tap the surface of the plate with a needle-nosed appliance to see if there is a big difference in the sound, if there is a change in the sound, it means that there is a cavity inside the plate.

Fourth, see if there is a smell. If the large core board emits a fragrant wood odor, it means that the formaldehyde release is less; If the smell is pungent, it means that the formaldehyde is released more, and it is best not to buy it. In addition, the greater the weight of the large core board, the more indicative it is that the board uses miscellaneous wood.

This kind of large core board made of miscellaneous wood cannot be nailed at all, so it cannot be used.

Generally, the thickness of the large core board is millimeter thick, and the thickness of the epidermis is millimeters, and the better brands are Ruijia, Baili, Dehejia, Kangcai, Pule, Montblanc, etc. The large core board can be divided into according to the advantages and disadvantages of the material and the texture of the surface material"Excellent"、"First class"and"Qualified products"。There are also enterprises that mark the plate grade as A-grade, double-A grade and triple-A grade, but this is only a corporate behavior, and there is no such thing in the national standard"Triple A"This kind of annotation is no longer allowed in the current market.

In use, the large core board can only be along the long side"Smooth open"It cannot be sawn horizontally. In addition, the large core board can not be used as a panel, and a layer of plywood should be pasted on the outside as a panel, otherwise it will come out.

Now paint blistering and other problems. Image wall floor material four (fireproof board).

Large core boardAlso known as blockboard, it is one of the main materials for home decoration, its core is spliced with natural wood strips, and a layer of wood skin is pasted on top and bottom. So what are the advantages and disadvantages of large core boards? What are the specifications of the large core board?

Below we will give you a detailed answer, I hope you can help after reading it.

What are the advantages and disadvantages of large core boards?

The advantages of the large core board: the large core board has good screw holding force, high strength, has the characteristics of firm quality, sound absorption, heat insulation, etc., and the moisture content is not high, between 10% and 13%, easy to process, used for furniture, doors and windows and sets, partitions, false walls, heating covers, curtain boxes, etc., the most widely used. Because the interior is solid wood, the requirements for processing equipment are not high, and the square high is closed for on-site construction.

In addition, the large core board is more stable than the solid wood board, but it is afraid of moisture, and attention should be paid to avoid using it in the kitchen and bathroom during construction.

Disadvantages of large core boards: due to the large use of urea aldehyde glue in the production process of large core board plates, the formaldehyde emission is generally high, and the environmental protection standards are generally low, which is why most of the large core board boards have a pungent taste. The solid branch wood strips inside the large core board are longitudinally spliced, so the bending and compressive strength of the vertical direction is poor, and the long-term stress will lead to the obvious transverse deformation of the board.

The solid wood strips inside the large core board are not of the same material, the density is different, and they are only simple to dry and easy to warp and deform; The structural posture is distorted and deformed, which affects the appearance and use effect.

What are the specifications of the large core board?

Now most of the market is solid, glue, double-sided sanding, five-layer large core board, there are two specifications, the size is the same only the thickness is different, the specifications are: 2440mmx1220mmx17mm and 2440mmx1220mmx15mm, good large core board in the middle of the stitch without seams, thickness to.

The total thickness of the adhesive veneer on both sides of the large core board shall not be less than 3mm. The width of the corner defects of all kinds of blockboards within the nominal format shall not exceed 5mm, and the length shall not be greater than 20mm. There are four thickness specifications: 12mm, 15mm, 18mm, and 20mm.

15mm and 18mm are the most commonly used thicknesses. You can choose according to the pressure and strength you are bearing, generally the thicker the higher the **.

The above is what are the advantages and disadvantages of the large core board brought to you? What are the specifications of the large core board? All of it.

The size of the large core board (commonly known as blockboard, woodworking board) is 1220 mm 2440mm. The surface of the large core board should be flat, without warping, deformation, blistering and depression; The core strips are arranged evenly and neatly, the gaps are small, and the core strips are free of decay, fracture, wormholes, knots, etc. If the large core board emits a fragrant wood odor, it means that the formaldehyde release is less; If the smell is pungent, it means that the formaldehyde is released.

Home decoration can only use E1 level of large core board, preferably E0 level, the industry Tengfei brand is better, but pay attention to fakes.

Man-made panels replaced the earlier solid wood as the main material used in furniture. There are many types of man-made panels, each with its own unique advantages. We can say that they have overcome the shortcomings of solid wood and are the main materials used in the current decoration construction, but it is often this kind of board that confuses consumers.

Therefore, before decorating, each semi-decorator should first take some time to figure out the common name and scientific name of various plates and the role in home decoration, advantages and disadvantages, so as to carefully select and control the quality according to the decoration needs when purchasing materials.

Blockboard Large core board The common name of blockboard is called large core board, which is the most basic material for decoration, which is made of two pieces of veneer in the middle of the sticky spliced board. **Slightly cheaper than a splint. Pros:

The processing technology is simple and the nail holding force is good. Disadvantages: Due to the combination of a variety of miscellaneous trees, the density difference is large, and it is easy to deform; High moisture content; high formaldehyde content; It cannot be used directly, it must be post-processed.

Usage: The commonly used processing method is to manually apply a single layer of veneer, and the back is treated with varnish, such as double-sided veneer, the price is doubled.
