Select the environmental protection grade of the board.
Is there an evaluation standard for the environmental protection of the board after leaving the factory-that is, the environmental protection grade? E 1 is the minimum environmental protection requirement for interior decoration. E0 grade is the highest environmental protection grade on the market at present. E0 grade (formaldehyde emission ≤0.5mg/L) and E/kloc-0 grade (formaldehyde emission ≤ 0.5mg/I~ 1.5mg/L). The degree of environmental protection is measured according to the amount of formaldehyde released.

Classification of picking boards
The following eco-boards, blockboard, medium density fiberboard and particleboard are often used in home decoration. Particleboard is a low-grade decorative material, which has poor nail holding power and low strength. Generally, it is mainly used for heat insulation, sound absorption or ceiling, making ordinary furniture, etc. Medium density fiberboard (MDF) is a man-made board made of plant fiber as the main raw material through crushing, soaking, hot pressing and drying. Wood board is a special kind of plywood, which is spliced together. Blockboard has the characteristics of good screw grip, high strength, firmness, sound absorption and heat insulation, but the glue content is slightly higher. Eco-board is a new type of environmental protection board, which is environmentally friendly and paint-free, reduces the pollution caused by secondary decoration, and is wear-resistant and scratch-resistant. Visual ecological board > wood board > medium density fiberboard > particleboard

Appearance quality of picking board
After obtaining the high-quality plate, it can be seen that its surface is flat and there are no obvious defects such as foaming; The thickness of the side plate is even, without hollowing out;
The plates with good quality are all affixed with detailed product descriptions, environmental protection grade labels and anti-counterfeiting labels, while the products with miscellaneous brands are unlabeled or the labels are simply and roughly made.

Choose a good plate brand
Common plate brands in the market are Bunny, Coconut King, Peng Hong, Qiu Jin, Moganshan, Millennium Ship, Fuxiang and Huang Mao. Good plate brands generally have after-sales service, good name image, complete product structure and test report.
Question 2: What board is better for decorating the house? The house should be decorated with high-quality and environmentally friendly plates. Baoyuan formaldehyde-free particleboard was selected for the renovation of the new house. Very satisfactory. It is said that isocyanate (PMDI) formaldehyde-free adhesive is used in the production of Baoyuan formaldehyde-free particleboard, which ensures the excellent environmental protection performance of particleboard and the quality is comparable to that of natural wood. Moreover, OSB is usually a three-layer structure, with the upper and lower layers of shavings arranged vertically and the core layer of shavings arranged horizontally. This crisscross structure makes it have extremely high dimensional stability and bending strength. In addition, there are a large number of long wood fibers, and the linear expansion coefficient is extremely small, so OSB has good earthquake resistance, impact resistance and bending strength.
Question 3: What brands are the top ten domestic plates? Bunny, Hong Kong Fulin, Coconut King, Millennium Boat, etc. , are all good.
Question 4: Which is the best plate for cabinets? In addition to melamine board, another common board on the market is multilayer plywood. This kind of cabinet board is mostly used in high-grade cabinets, especially solid wood door panels and antique coated door panels. The advantages of this cabinet are: strong environmental protection, closest to the surface structure of solid wood, super nail holding power, waterproof and strong deformation resistance. But no product is perfect, especially in China, a country with extremely pioneering ideas. Here I have to talk about several existing forms of multi-layer plywood. Multilayer board, as its name implies, is a board made of laminated board. Each layer is a thin veneer of rotary cutting wood, so from this point of view, this is the board closest to the log. However, the arrangement of each layer of plates is different, which leads to some differences in the properties of finished plates. According to the different properties of the board, there are several commonly used names: ordinary multilayer board, LVL board and LVB board. To put it simply, the common multi-layer board belongs to the "cross structure", and the arrangement mode of this kind of sheet is continuous in one horizontal direction and one vertical direction, and the flatness of the formed board is relatively good, but the thickness of the surface veneer is generally thin, and there are many stubbles in the cross section of the board, which is not conducive to processing and affects the appearance; Laminated veneer lumber is a longitudinal structural mechanism. This kind of plate is characterized by good surface finish and no burr, but the stress and deformation are too great. LVB board is a new type of board which combines the advantages of two kinds of boards, and basically solves the problems of surface smoothness, stubble and deformation. It is the most suitable plate for the whole cabinet. Multilayer boards are generally used in the following processes when making cabinets. 1. After the surface of the multilayer board is pasted with melamine impregnated paper, PVC edge sealing is carried out. All other processing techniques are the same as melamine board; 2. Stick the solid wood veneer on the surface of the multilayer board, seal the edge of the veneer and spray it. Other processes are the same as melamine board; 3. The surface of the multilayer board is coated with solid wood veneer without edge sealing, and other processes are the same as melamine board; The first method is usually used for LVL board; The second method is often used for ordinary plywood; The third method is often used for LVB paperboard. The above instructions are for reference when purchasing. In addition, there are some plates on the market, such as glued laminated timber and blockboard. Of course, foam board, waterproof board, bridge mechanical board, ecological board and other boards are called "non-mainstream" with a fashionable word, so I don't need to go into details. The following is just a simple explanation, and everyone will know after listening. Plywood: The advantage is that it is infinitely close to the log, but the disadvantage is that the splicing board of Plywood often uses materials of different tree species and the same age, which leads to different parameters of the board and deformation and cracking. Blockboard: The advantage is that it is close to solid wood, which is accepted by the public. The disadvantage is that a few manufacturers can make hollow boards, and there are gaps in the splicing of small boards. Hehe, so this kind of board, except for its particularly good quality, can only look at luck; Other plate types will not be introduced, for the simple reason: new products or new names are in the market verification stage, and no predictive evaluation is made.
Question 5: What kind of furniture board is better? How to choose the type? The quality of furniture board mainly depends on whether it is suitable for your own use and your own budget. You can refer to the following points when choosing a category:
First, distinguish different plates.
Customized furniture market commonly used density board, solid wood particle board, solid wood multilayer board. To judge and distinguish the classification of customized furniture plates, the most direct way is to look at the cut surface of the template.
Seen from the cross section, the density board is made of powdered wood fibers by high temperature and high pressure pressing. The combination is relatively tight, the surface finish is high, but the weight is relatively large. Powdered fiber absorbs moisture more easily than other plates, so its moisture-proof performance is almost the same as that of other plates, and the use will not be affected if the edge is sealed in place.
Solid wood particle board is made of wood particle structure by high temperature and high pressure pressing, so it is named Gu. The combination of solid wood particle board is not as tight as density board, so the weight is lighter, and some poor quality can even see small pores. Solid wood particleboard is one of the most commonly used panel furniture materials in the industry at present, which has the advantages of difficult deformation and strong nail grip.
Solid wood multilayer board is made of three or more layers of single board or thin board at high temperature and high pressure. Solid wood multilayer board has the advantages of small deformation, high strength, good internal quality and good flatness.
Second,
Looking for environmentally friendly plates
Whether the plate is environmentally friendly depends mainly on its formaldehyde emission. We mainly take E2 grade and E 1 grade as environmental protection standards. Many merchants claim that their plates are E0 grade or even beyond E0 grade. At present, there is no such standard in China, so it needs to be identified when testing. The formaldehyde emission of E2 grade board is less than 5mg/L, which is generally limited to outdoor use, and indoor use must be closed. The formaldehyde emission of E 1 grade board is less than 1.5mg/L, which can be directly used indoors. Now some businesses advertise themselves as "zero formaldehyde" and "formaldehyde-free" boards. As long as they are artificial boards, they will basically contain formaldehyde. The most direct way to judge whether the formaldehyde content of the board exceeds the standard is to open the wardrobe door or open the drawer. If there is a strong * * *, or the eyes are smoked, it is basically that the formaldehyde content exceeds the standard. Therefore, it is best to order furniture from a regular and well-known overall wardrobe brand merchant, and at the same time ask the merchant to show the material inspection report.
Third,
Look at this veneer
At present, the plates used in the production of panel furniture are all green melamine decorative plates pressed at high temperature and high pressure. The decorative board made of this material has high surface strength, wear resistance, scratch resistance and high temperature resistance. However, some small manufacturers are shoddy. Although the surface looks smooth and beautiful, it gives a good feeling. But with a slight stroke of the key and nail, there will be obvious scratches. This decorative board not only has poor wear resistance, but also is not fireproof.
Fourth, look at the edge sealing of the plate.
The process of the whole factory can also be seen from a small detail of the edge sealing of the plate. Professional custom furniture manufacturers use automatic CNC precision cutting saw to cut plates, and there is no edge collapse around the plates. Then use automatic edge banding machine to edge banding. Good sealing edges are generally the same color, with smooth and round edges, tight seams, obvious edges and delicate corners. However, due to the limited equipment, many small manufacturers use manual edge sealing, and the edge sealing strip is easy to fall off, the edge is rough, and it is easy to swell due to moisture, which leads to the deformation of the plate. Pay attention to whether the surroundings are sealed when buying. Only by sealing all around can the moisture in the air be effectively prevented from invading the interior of the board and releasing formaldehyde.
Question 6: Which is better, solid wood furniture or panel furniture? Solid wood furniture, which is normally sold in the market and recognized in the industry, refers to the boards used in furniture: solid wood wide parquet, solid wood laminated wood and solid wood parquet.
The wide splicing of solid wood refers to the board made by processing hardwood into narrow strips (about 3-6cm, and a small amount of wide strips), then gluing and splicing horizontally, and then sanding up and down.
Solid wood glulam refers to the boards that connect narrow and short strips of wood with adhesive (some boards are connected by teeth) and then the upper and lower sides are widened horizontally and sanded.
Solid wood parquet refers to a board made of narrow strips of wood with small specifications, which are horizontally glued and sanded up and down, and then pressed with patterns on the upper and lower sides, and the hardwood with good wood properties is cut into veneers.
The advantages of solid wood wide mosaic are: strong sense of solid wood appearance, more three-dimensional sense and less sizing.
The disadvantages of solid wood wide mosaic are: 1. Because of the anisotropy of hardwood, the wide mosaic is easy to deform, and the glue joints between plates are exposed, so you can directly see the messy lines between plates, and the firmness of splicing has a great influence on whether the plates can crack. In addition, the moisture in the paint will affect the wood during the painting process. Even if the newly processed products are flat, the surface of solid wood wide mosaic is prone to uneven edges and glue seams in daily use. With the passage of time, these phenomena will become more obvious due to the humidity of the air. Moreover, the wider and thicker the mosaic substrate is, the more obvious the problem is.
2. In addition, due to the different textures and hardness of the slats, the thickness of each slat can't be consistent even with a sander with a fixed thickness, which leads to the unevenness of each slat on the surface of the plate. After brushing, the unevenness of each slat is more obvious.
3. If the quality of transverse stitching is poor, you can still see obvious transverse stitching. If the transverse strength is not enough, it is easy to crack at the glue joint. Therefore, if you look at the paint surface of furniture obliquely against the light, you can see the height of slats and the bonding between slats. With exquisite materials and scientific technology, this phenomenon will be smaller, but it cannot be avoided fundamentally.
4. The furniture board made by this process has high requirements for material selection, and the color, texture and growth period of the board are all basic requirements, resulting in low wood utilization rate, great waste and high cost. Especially the growth period determines the hardness of wood and directly affects the probability of deformation during use. This feature is almost difficult to distinguish in painted household products, and can only be found after long-term use. Even if the material selection is very strict, the large-scale furniture, such as countertops and door panels, still lacks a sense of integrity, and the slightly messy wood grain can't create a calm and gentle overall atmosphere.
The technology of solid wood glulam is basically the same as that of solid wood wide splicing, but due to the small material specifications, there are more splicing in the length direction. The disadvantages of solid wood glulam are often more prominent, but the advantages are far from there, and the sizing amount is much higher than that of solid wood wide mosaic.
The advantages of solid wood splicing are: 1. Because the core board is made of wood with small anisotropy, the surface unevenness and warping degree of the board are small, and the upper and lower sides are covered with two layers of thin veneer, which can better eliminate the warping, cracking and deformation of the board and improve the physical strength of the board in all directions. 2. Planted veneer is an excellent large-diameter log, which is selected strictly according to texture and color, and made by high-precision equipment and scientific planing method. This treatment process has a very good sense of integrity in texture and color, and the texture is more prominent after painting. The whole set of furniture produced can create a harmonious and high-grade sense of value. 3. After the solid wood panel is painted, there will be no glue joint and uneven lath on the surface, and the physical properties are relatively stable during long-term use. 4. The utilization rate of wood is high, which accords with the principle of ecological utilization of raw materials. Therefore, in terms of use and texture color, the solid wood mosaic decorative board is more suitable for the use and decorative function of furniture. 5. Although the sizing amount of solid wood panel is larger than that of solid wood wide panel, it is more environmentally friendly and healthy because of the protection of double-sided thick veneer and only eight glue seams on both sides and four sides of thick veneer.
Question 7: What kind of plate is good for wardrobe? What are the characteristics of various plates? 1, solid wood patch panel: solid wood patch panel is a good panel in terms of cost, but it has been high for a long time, but it is lower than solid wood and is not easy to deform and crack at high temperature. At present, there are six or seven kinds of boards, such as oak boards, ash boards and elm boards. From the point of view of environmental protection, the patch panel only needs a little glue at the plug-in place, compared with the wood density board.
2. joinery board (commonly known as large core board): joinery board is a core board made of wood strips bonded with glue, and then both sides are glued with veneers. At present, the thickness of domestic joinery boards is mostly 20-25mm, but the thickness of joinery boards on the market is basically1.6-2.0mm.. Cabinetwork is characterized by strong toughness, strong load-bearing, not easy to crack, moisture-proof, strong nail grip and easy processing, so it is widely used in various fields. Poplar and Chinese fir are the most common in the market. Its defect is that only a thin layer of veneer can be attached to the surface, and many problems are easy to occur when the materials are not well combined.
3. High-density board (fiberboard): High-density board is made of wood, branches, etc. Soaking in water for a period of time, crushing and pressing. It is made of wood fiber or other plants by gluing. According to different densities, it is divided into high, medium and low. It is widely used because of its high strength, impact resistance and easy processing.
4. Particleboard (particle board): This kind of board is made of branches, sawdust and other particles, with a large amount of glue and low cost. But the strength is not big, and the formaldehyde content is high. Try not to use this kind of plate when making a wardrobe.
5. Multilayer board (plywood is also called plywood): plywood is also called thin core board. Plywood is made of three or more boards glued together, which is waterproof and moisture-proof. Because of its small deformation, large width and strong transverse tensile strength, it is widely used in cabinets, cabinets, tables and chairs and other fields. This kind of board uses more glue than blockboard, but it is more suitable for making wardrobes than blockboard. Because the joinery board is made by splicing and pasting wooden strips, once the nail touches the seam, it is easy to fall off and the span cannot be too large. When the span is large, it is easy to deform. Therefore, multi-layer boards were the most furniture at that time.

Question 9: What board should be used for furniture? Comparative cognition of wood-based panel furniture and solid wood furniture Solid wood furniture refers to furniture made of natural wood, and the texture of wood can be seen on the surface of furniture. There are roughly two kinds of solid wood furniture on the market at present. One is pure solid wood furniture, and all the materials of furniture are solid wood, including desktop, door panel, cabinet side panel and so on. , made of pure solid wood, without using any other artificial board. The other is imitation solid wood furniture, that is, the natural texture, feel and color of wood are exactly the same as solid wood furniture in appearance, but they are actually made of solid wood and man-made boards, such as particleboard or medium density fiberboard with veneers for side panels and shelves, while solid wood is used for doors and drawers. The main problem of solid wood furniture is that the change of moisture content makes it easy to deform, so it can't be exposed to direct sunlight, and the indoor temperature can't be too high or too low. Too dry and humid environment is not suitable for solid wood furniture. In addition, the component combination of solid wood furniture usually adopts tenon structure and adhesive, and the finished product can not be disassembled generally, which is very inconvenient to carry. Advantages of wood-based panel furniture The combination of wood-based panel furniture parts usually adopts all kinds of metal hardware, which is very convenient to disassemble and assemble, and the furniture with high processing precision can be disassembled and assembled many times. Because there are many kinds of veneers, the change of color and texture can give people different feelings, and there are also many changes in modeling design, which are personalized and not easy to deform. Disadvantages of wood-based panel furniture The problems of wood-based panel furniture are mostly environmental problems. If the furniture is made of particleboard and other materials, it is easy to release formaldehyde that pollutes the environment and is harmful to human body if it is not completely wrapped when it is faced and sealed. Generally speaking, if you open a cupboard door or drawer, if there is a strong * * *, most of it is formaldehyde exceeding the standard, so this kind of furniture should not be purchased. Selection of Wood-based Panel Wood-based Panel is a panel made by mixing the corner waste produced during wood processing with other fibers. There are many kinds of wood-based panels, such as particleboard, medium density board, blockboard (large core board), plywood, fireproof board and so on, which can be used in different parts of the family according to their own characteristics. Particleboard makes furniture plates diversified. Particleboard is an artificial board made of chips, sawdust, etc. In the process of processing wood into chips with certain specifications, it is dried, mixed with adhesive, hardener and waterproof agent, and pressed at a certain temperature. Because of its uniform structure and good processability, particleboard can be processed into large-format plates as needed, which is a good raw material for making furniture with different specifications and styles. The finished particleboard can be used directly without drying again, and has good sound absorption and sound insulation performance. But it also has its inherent shortcomings, because the edge is rough and easy to absorb moisture, so the edge sealing technology of particleboard furniture is particularly important. Medium density fiberboard improves aesthetics. Medium density fiberboard is an artificial board made of wood or plant fiber, which is mechanically separated and chemically treated, added with adhesive and waterproof agent, and then molded at high temperature and high pressure. The structure of MDF is more uniform than that of natural wood, and it also avoids problems such as decay and moth-eaten. At the same time, the expansion and contraction are small and easy to process. Because the surface of MDF is flat, it is easy to paste various finishes, which can make furniture more beautiful. Various decorative wood-based panels beautify the home. Wood-based panel for decoration is the product of secondary processing of ordinary wood-based panel. According to the decorative materials, there are natural wood-based panels, plastic wood-based panels, paper-based panels and other types. Fireproof board, also known as "plastic veneer wood-based panel", has excellent wear resistance, flame retardancy, easy cleaning and water resistance. This kind of wood-based panel is a good material for table tops, kitchen furniture and bathroom furniture. Paper-based man-made board is a special paper-based decorative material with wood grain or other patterns on its surface. Its various surface properties are slightly worse than those of plastic veneer wood-based panels, such as Polaroid panels and gorgeous panels.
Question 10: What kind of plate is better for the whole wardrobe? At present, there are about three kinds of wardrobe plates: 1. Medium density fiberboard, 2. Plywood, 3. Incense board
Medium density fiberboard is a kind of density board, including long fiberboard and short fiberboard. Wood fiber or other plant fibers are used as raw materials, which are crushed, separated, dried, coated with urea-formaldehyde resin or other suitable adhesives, and then hot-pressed. Its density is generally in the range of 0.5-0.8g/cm3, and its thickness is generally 3-30mm.
Plywood, also known as plywood, is commonly known as thin core board in the industry. It is made of three or more layers of veneer or thin plate with a thickness of one millimeter by hot pressing. It is the most commonly used material for handmade furniture at present. The moisture resistance of plywood is much better than that of MDF.
Xiangxiang board is a new type of eco-friendly man-made board, which is made of crop straws such as rice and wheat in nature as the main raw materials, polyurethane eco-adhesive completely free of formaldehyde as the adhesive, and advanced national patent technology. Zero Border Fragrant Board "―― the first wood-based panel in China that does not release formaldehyde! It has the advantages of wood particleboard and medium density fiberboard, and can be widely used in interior decoration, furniture manufacturing, floors, kitchen cabinets, sound absorption boards, writing boards, drawing boards and packaging materials. It is an ideal substitute for wood-based panels. Lotus fragrance board is a truly environmentally friendly and harmless board. It is recommended to use this board when making a wardrobe, which is of great benefit to the family.
If you want to know more specifically, you should still search for Olongweigao in Baidu. This brand is prepared for the application of these three kinds of plates. I suggest you get to know it.
