[ Chinese wardrobe net ] In the decoration, whether it is to buy ready-made wardrobes or processing wardrobes, including home wooden doors, often encounter obstacles in material selection. The products on the market, what kind of materials are acceptable for environmentally friendly prices? Below, we will review the main types of wood panels on the market, hoping to help everyone.
Wood board
Wood board is commonly known as a large core board. It is a plywood with a solid wood core. Its vertical direction (different from the core wood board) is resistant to bending and bending. Most of the market is solid, rubberized, double-sided sanding, five-layer blockboard, which is one of the most commonly used wood panels in the current decoration.
Advantages: good clamping force, high strength, quality, sound absorption, heat insulation, etc., can be used to make furniture, doors and windows and sets, partitions, false walls, heating covers, curtain boxes, etc. Because the interior is solid wood strip, the requirements for processing equipment are not high, which is convenient for on-site construction.
Disadvantages: Due to the large use of urethane glue in the production process of wood board, the formaldehyde emission is generally higher; at present, some wood board production in the market is cut corners, the gap is larger when splicing solid wood strips, and there are holes in the wooden board. The inner solid wood strip is longitudinally spliced, and the vertical bending resistance is poor. The long-term stress will cause the wood board to be obviously horizontal and easy to warp and deform.
Particle board
Particleboard is a kind of artificial board which is made by cutting various branches, small diameter wood, fast-growing wood, wood chips, etc. into a certain size, dried, mixed with glue, and pressed under a certain temperature and pressure, because its profile is similar to honeycomb. So called the particle board. Adding certain materials such as “moisture-proof factor†or “moisture-proof agent†inside the particle board becomes a moisture-proof particle board. Because of the small expansion coefficient after absorbing moisture, it is widely used in cabinets, bathroom cabinets and other environmentally-friendly cabinet products. Profiles such as solid wood particle board and fiberboard are similar to particleboard, but the materials and processing techniques are more particular, and the environmental protection factor is improved.
Advantages: good sound absorption and sound insulation performance, good thermal insulation effect; internal granularity with cross-displacement structure, good nail holding power; strong moisture resistance, small expansion coefficient after absorbing moisture; smooth surface, realistic texture, pollution resistance , resistant to aging.
Disadvantages: The internal structure is granular. Once the surface skin is peeled off, the strength of the whole wooden board will be greatly reduced. Due to its internal structural characteristics, the amount of glue used is large and the environmental protection coefficient is low.
Solid wood finger joint
The finger joint board is a small piece of solid wood that will be processed by deep processing. It adopts a jagged interface, which is similar to the cross-docking of two fingers, so it is called the finger joint board. Since the logs are cross-joined, they are forced by each other, and because the surface plates are not required to be glued up and down, the amount of glue used is low.
Advantages: Since the solid wood plate has fewer joints and less glue, the environmental protection factor is relatively high.
Disadvantages: Because it is a whole piece of solid wood, it is prone to deformation and cracking in an environment with large temperature and humidity changes.
Multi-layer solid wood board
The multi-layer solid wood board is made of multi-layer plywood arranged in a crisscross pattern, and the surface is made of high-quality solid wood veneer or technical wood as a fabric, and is formed by cold pressing, hot pressing, sanding and the like. Due to the non-deformable characteristics of the multi-layer solid wood board and the excellent performance of adjusting the indoor temperature and humidity, the surface layer of solid wood skin material and feel is better, which is favored by consumers.
The multi-layer solid wood board has the advantages of good structural stability, non-deformation, and firmness. Due to the vertical and horizontal gluing, high temperature and high pressure, the deformation defects of solid wood wooden plates are solved from the internal stress, and the amount of glue used is less than that of wood chips such as particleboard.
Due to the limitations of their own materials, each wooden board will use glue, and the release of formaldehyde and the amount of glue are inextricably linked. As for the quality of the glue, the construction process of the wood board, the storage time of the wood board, the temperature and humidity of the environment after the decoration enters, will affect the release of formaldehyde. If you are making furniture on site, it is best to use finger jointed laminates to greatly improve environmental performance. However, the surface painting should choose a high environmental protection factor, otherwise it will not be worth the candle. The choice of finished products depends on the brand and whether it meets national standards. Although formaldehyde is a toxic substance, everyone does not have to talk about formaldehyde and change color. Choosing the right materials for your own situation will make your home more environmentally friendly.
