I believe that the decoration of friends for what is a wood board must not be unfamiliar to the so-called wood board is the big board we often mentioned, it is made of two pieces of veneer glued wood board. It is generally used for decoration as a wooden building material. Then, the next small series for everyone to introduce what is the advantages and disadvantages of wood board and wood board.
What is a wood board
The wood board is commonly known as the big core board, which is formed by two pieces of veneer pressed and spliced ​​together. The total thickness of the glued veneer on both sides of the wood board shall not be less than 3mm. All kinds of wood board edge defects, the width within the nominal range shall not exceed 5mm, the length shall not exceed 20mm. The middle board is made of high-quality natural wood board heat treated (ie, drying room drying), processed into a certain specifications of the wooden strip, made by the puzzle machine splicing. The spliced ​​wood boards are covered on both sides with two layers of high-quality veneers, which are then compressed by cold and hot presses.
What are the advantages and disadvantages of wood board?
Woodboard advantages
1. Blockboard screws have good grip strength, high strength, and are characterized by toughness, sound absorption, heat insulation, etc. The moisture content of blockboard is not high, between 10% and 13%, and processing is simple. It is used for furniture, doors and windows. Sets, partitions, false walls, heating covers, curtain boxes, etc. are the most widely used.
2. Since the interior is a solid wood strip, the requirements for processing equipment are not high enough to facilitate on-site construction.
Wood board defects
1. Due to the large amount of urea-formaldehyde glue used in wood board production, formaldehyde emission is generally higher, and environmental standards are generally low. This is why most wood boards taste pungent.
2, most of the current market wood board production cut corners, in the splicing of solid wood when the gap is larger, the plate is generally hollow inside, if the cracks in the cracks, then basically no nail holding power.
3. The solid wood strips inside the wood board are longitudinally spliced, so the vertical bending strength is poor, and the long-term stress will cause significant lateral deformation of the board.
4. The wood strips inside the wood board are not the same in material and density, but only after simple drying process, they are easy to warp; the structure is distorted and deformed, which affects the appearance and use effect.
5, due to the rough surface of the wood board, so the carpentry on-site processing, in the treatment of the surface usually use a lot of glue or paint, so the sheet produced by the furniture is not environmentally friendly, which is why the decoration taste is very exciting The reason is that such on-site furniture is the culprit for carcinogenesis and genetic mutations, and it is very harmful to the human body.
Editor's summary: What are the advantages and disadvantages of what are the wood board and wood board? It is introduced here, and I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
