Which kind of sheet is less solid? Which kind of sheet is more environmentally friendly?

[Chinese wardrobe net] The panels of the wardrobe do not choose less formaldehyde, environmentally friendly sheet, you want to make the indoor formaldehyde less? First understand the problem of which kind of sheet metal is less in the wardrobe, in order to better make indoor formaldehyde less.

Solid wood board

Introduction: As the name suggests, solid wood panels are wood panels made from complete wood. Solid wood boards are generally classified according to the physical name of the board, and there is no uniform standard specification.

Features: Solid wood panels are durable and natural, and most of the solid wood panels have a special wood aroma, so the price is not cheap.

Uses: Because of the price problem, the chances of solid wood panels used in wardrobes and decoration are not many. The most common solid wood panel building materials on the market are solid wood flooring, followed by expensive solid wood wardrobes .

How to choose: Look at the surface, high-quality wood is sliced ​​after several processes such as drying and degreasing, so the surface should not have decay, dead knots, wormholes, cracks, etc.; weighing, the heavier the weight of the board, the pressure is proved The denser, especially the solid wood floor; the thickness, the thicker the base layer, the stronger the strength of the board.

Solid wood finger joint

Introduction: Finger joint board, also known as integrated board, laminated material, finger joint material, that is, a piece of solid wood piece that has been processed by deep processing like a "finger head", because the wooden board uses a jagged interface, similar The fingers of both hands are crossed and docked, so it is called the finger joint board. Since the raw wood strips are cross-coupled, such a combined structure has a certain bonding force, and since the surface plate is not required to be adhered up and down, the glue used is extremely small.

Features: Due to the small number of joints of solid wood panels, the amount of glue used is also small, so the environmental protection factor is relatively high. Easy to process, can be cut, drilled, sawed and shaped. The disadvantage is that it is easily deformed and cracked.

Uses: Mainly used for wooden door fans, high-end wardrobes, etc.

How to choose: The solid wood distinguishes the finger joint board, mainly depends on the core material annual ring, the finger joint board is mostly made of Chinese fir, the annual ring is more obvious, the larger the annual ring, the longer the age of the tree, the material of the finger joint plate produced is also The better. One way is to look at the tooth prints. Finger joint plates are usually divided into bright teeth and dark teeth, of which the finger joint plates with dark teeth are preferred. The harder the wood, the better the quality of the fingerboard, because its deformation is much smaller than the average plate, and the pattern is more beautiful.

Splint

Introduction: Plywood, also known as plywood, is commonly known as fine core board. It is made of three or more layers of one-millimeter thick veneer or sheet adhesive. It is the most commonly used material for hand-made furniture. The splint is generally divided into three specifications of 3 PCT (commonly known as plywood), 5 PCT, 9 PCT, 12 PCT, 15 PCT and 18 PCT (1 PCT is 1 mm).

Features: 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.

Uses: Plywood is often used in all kinds of wood products such as panel wardrobes, background walls, ceilings, etc., used for the bottom panel of decorative panels.

How to choose: When purchasing, you should see if the splint has bubble degumming, whether the core board has large gap, whether the panel color is consistent, cracks, wormholes, bruises, stains, defects and repairing adhesive tape can not be Appearance; also need to pay attention to its formaldehyde emission and intensity; should choose a clear, shiny, smooth sheet of wood.

Blockboard

Introduction: Blockboard, commonly known as large core board, wood board. The large core board is made of two pieces of veneer in the middle of the veneer. The price of the large core board is cheaper than that of the thin core board, and the vertical direction (differentiated by the core material direction) is poor in bending resistance, but the lateral bending strength is high.

Features: Blockboard has good clamping force, high strength, hard texture, sound absorption and heat insulation. The moisture content of this board is between 10-13%, which is easy to process, so it is very popular among consumers. .

Uses: Because the surface of blockboard is flat and not easy to be deformed, it is widely used, and is mostly used for wardrobes, doors and windows, partitions, false walls, curtain boxes, etc. However, if you are afraid of moisture, you should avoid using it in the kitchen.

How to choose: How to distinguish the quality of blockboard? Firstly, look at the flatness of the surface of the board, without warping, deformation, no bubbles, depression is better; secondly, because the board contains wood strips, it is necessary to see if the core strips are evenly arranged. Neat, small gap, no broken core, broken, wormhole and thrift; can also pick up the corner of the sheet and shake it. If the sound is loud, the gap between the strips will be large, which will affect the nail holding force.

Particle board

Introduction: Particleboard, also known as particle board and bagasse board, is a thin sheet made of wood scrap as the main raw material, then added with glue, and the additive is pressed. According to the pressing method, it can be divided into two types: extruded particle board and flat pressed particle board.

Features: The main advantage of this type of sheet is that it is extremely cheap. At the same time, due to the large wood fiber of the particle board, the expansion rate after soaking water is not high. The shortcomings are also obvious: the strength is extremely poor. It is generally not suitable to make furniture with larger or mechanical requirements.

Uses: The substrate for melamine panels, which is widely used in the cabinet market, is particleboard. After processing, particleboard can also be used on furniture parts.

Particle board

Introduction: The so-called solid wood particle board is a kind of particle board, also called homogenized particle board. The scientific name is oriented structure particle board. A scrap made of wood or other lignocellulosic material, with fine wood fibers on both sides, long wood fiber in the middle, and a synthetic board glued under the action of heat and pressure after applying the adhesive, which is a board produced by the particleboard process. . The main difference between him and the particle board is that the internal structure is more symmetrical, so the stability is better.

Features: strong decorative performance, warpage is not easy to deform, strong nail holding power, good processing performance.

Uses: As a new type of high-grade environmentally friendly substrate, solid wood particle board has been widely used by furniture manufacturers in Europe and the United States. The domestic high-end panel furniture market has also begun to adopt this type of board in large areas.

How to choose: the surface is flat, no empty drum, no degumming; use the nose to smell no smell, check the certificate, showing that the formaldehyde content is within the national standard.

MDF

Introduction: MDF, also known as fiberboard. It is made of lignocellulosic or other plant fiber, and the artificial board made of urea-formaldehyde resin or other suitable adhesive is divided into high-density board, medium-density board and low-density board according to its density. MDF is also easy to rework due to its soft and impact resistant properties. In foreign countries, MDF is a good material for making furniture, but because the national standards for height plates are several times lower than international standards, the quality of MDF use in China needs to be improved.

Features: Its base material is also particleboard and MDF. It is made of substrate and surface. The surface veneers are mainly made of domestic and imported. Because they are treated by fireproof, anti-wear and waterproof soaking, The effect is similar to that of composite wood flooring.

Uses: High-density board is mainly used for interior decoration of wall panels and partitions; medium-density board is more suitable for wardrobe furniture; laminate flooring is also made of MDF.

How to choose: the surface is clean, smooth and flat, it is best to choose a plate with better elasticity; since the MDF is made of glue, try to choose E1 grade material with high environmental protection coefficient, even E0 grade material.

Melamine board

Introduction: Melamine board, referred to as tricyanide board, is more like the eco-board in the industry. The full name is melamine impregnated film paper veneer wood-based panel. The melamine board is also called double-decorative panel, paint-free board and ecological board. It is also called a molding board.

About environmental protection: The decorative paper is soaked in a melamine solution, and then hot pressed to become a melamine board. Therefore, the moisture-proof board for furniture is generally called melamine moisture-proof board. Melamine formaldehyde resin is a kind of solution containing very low formaldehyde. It is environmentally friendly, so that it will not cause 2 pollutions, but will reduce the release of the inner substrate. This kind of treatment has been recognized by everyone, and most of them are doing this.

Main classification: According to the internal fiber form, it can be divided into melamine particle board and melamine density board. The substrate of melamine particle board is made of wood into granules and wood chips, which are formed by re-arrangement, hot pressing and glue drying; melamine density board The substrate is made of sawdust, which is formed by redirection, hot pressing and gel drying. The difference between the two is that the particle board has high strength, strong nail suction ability, and the density board is relatively weak.

Uses: Commonly used in interior architecture and decoration of various furniture and cabinets. Some panels, walls, counters, cabinets, etc., melamine panels are a wall decoration material. It is not suitable to use melamine board counterfeit composite flooring for floor decoration.

How to choose: Since these plates are made of glue, try to choose E1 materials with higher environmental protection factor, even E0 materials.

Acrylic sheet

Introduction: Acrylic sheet is a specially processed plexiglass, which has the reputation of “plastic queen”. It has good color and high transparency.

Features: The advantages are excellent weather resistance, good transparency and good plasticity. The disadvantages are low hardness, poor heat resistance and low elongation, so it is easy to crack, brittle, easy to deform, and the color is unstable, and fluffing is likely to occur during use. In addition, it also contains substances harmful to the human body.

What kind of board is considered environmentally friendly

In fact, most of the materials that can be used in our custom homes, apart from solid wood, the biggest difference between them is the difference in the base material and production process, which leads to the difference in environmental protection and stability, and the more intuitive is reflected in the price. on.

The fingerboard or integrated board is the closest to the solid wood in environmental protection, but the price is a little cheaper. Therefore, the solid wood of the wardrobe at home is basically made of integrated boards, and the splint and wood board are better because of their stability. Easy to process, etc., the price has come down again, so it is generally used in the back panel of the wardrobe to make a shoe cabinet.

Nowadays, the finished wardrobes, cabinets, etc. on the market are basically based on particleboard, particle board, MDF, MDF, and paint-free board.

The environmental protection that everyone cares about most can be arranged in order from good to bad: solid wood - integrated board - wood board - multi-layer board - particle board - MDF.

The above is all the information, I hope I can help you.
