Panel furniture refers to furniture made of medium density fiberboard or particleboard by surface veneer and other processes.
Panel furniture is a kind of assembled furniture with wood-based panels as the main substrate and boards as the basic structure, all of which are connected by artificial boards with decorative surfaces and hardware.
Answer: The advantages of panel furniture.
1, make full use of wood, and the price is moderate. Panel furniture is mainly made of wood or particleboard and fiberboard with moderate density, so its raw materials and processing costs are not high, and the price of the furniture made is relatively moderate, which can meet the consumption requirements of all consumer classes and improve the utilization rate of wood.
2, three-dimensional shape, not easy to deform. Compared with solid wood furniture, panel furniture is different from its physical structure, the moisture content of its wood is strictly controlled, it is not easy to be deformed by the influence of temperature and air humidity, and the modeling stability is improved. Furniture that is not easy to deform will certainly be welcomed by the public.
3, a variety of colors, fashionable. Generally, panel furniture can be decorated with decorative veneers, so many shapes can be designed and their colors can be arbitrary, which is in line with the personality pursuit of young people. This feature satisfies the aesthetics of more people and is also the main reason for its popularity.
Three answers: panel furniture materials
1. particleboard.
It is an artificial board made of wood processing residues, sawdust and so on. Granulating, drying, mixing with rubber, curing agent and waterproof agent, and pressing at a certain temperature. Because its cross section is similar to honeycomb, it is called particleboard. Advantages: The inside is staggered particles, so it has good nail holding power, good lateral bearing capacity and lower cost than density board. Although the formaldehyde content is higher than that of MDF, the price is relatively cheap.
Disadvantages: due to the simple preparation method, great quality difference, difficult to distinguish, poor bending and tensile properties, loose density and easy to loosen.
2. Medium density board.
This kind of artificial board is made of wood fiber or other plant fiber as raw material and molded by urea-formaldehyde resin or other suitable adhesive at high temperature and high pressure, so it is called density board. Making the medium density board with the density of 0.5-0.88g/cm3. The density below 0.5 is generally called fiberboard, and the density above 0.88 is called high-density board.
Advantages: good physical properties, uniform material, mechanical properties close to wood, no dehydration problem, so it will not be deformed by moisture. Some surfaces are decorated with melamine, which is moisture-proof, corrosion-resistant, wear-resistant and high temperature-resistant, and does not need post-treatment, so the formaldehyde content is low.
Disadvantages: high machining accuracy and technological requirements (due to high density, it must be cut with a secret saw); Poor nail grip; Not suitable for processing at the decoration site; The cost is high. According to the difference and thickness between imported veneer and domestic veneer, the price of each veneer ranges from 80 yuan to 200 yuan.
3. Blockboard
It is made of two pieces of plywood glued together. The total thickness of glued veneer on both sides of blockboard shall not be less than 3 mm, and the width and length of corner defects of all kinds of blockboard shall not exceed 5mm in the nominal format. The medium plate is made of high-quality natural plate, which is processed into strips with certain specifications after heat treatment (that is, drying in a drying room) and spliced by a splicing machine. Two layers of high-quality veneers are covered on both sides of the splicing board, and then glued by a cold and hot press to make solid wood veneers.
Advantages: the joinery board has the characteristics of good screw grip, high strength, firmness, sound absorption and heat insulation. The moisture content of blockboard is not high, which is between 10%- 13%, so it is easy to process. Widely used in furniture, doors and windows, door and window covers, partitions, fake walls, heating covers, curtain boxes and so on. Because the inside is
Disadvantages: the environmental protection standard is generally low, and there is no nail holding power. Long-term stress will lead to obvious lateral deformation of the plate. The solid wood strips inside the blockboard are different in material and density, and are easy to warp and deform after simple drying. The structure is twisted and deformed, which affects the appearance and use effect. Because of the rough surface of joinery board, a lot of glue or paint is usually used when processing the surface on site, so the furniture made of this board is extremely environmentally unfriendly, which is also the main reason for the pungent smell when decorating. This kind of on-site furniture is the chief culprit of cancer and genetic mutation, which is very harmful to human body.
4. fragrant board.
Fragrant board is a new type of eco-friendly man-made board, which is mainly made of crop straw scraps, made of polyurethane eco-adhesive completely free of formaldehyde, and developed with advanced national patent technology. Lingjie incense board can be widely used in interior decoration, furniture manufacturing, floors, kitchen cabinets, sound-absorbing boards, writing boards, drawing boards and packaging materials, and can widely replace man-made boards and natural wood.
Advantages: the durability, bearing capacity and deformation resistance of incense board reach the national particleboard standard, which is no less than that of wood-based panels. At present, the straw fiber raw material used in incense board has a large number of natural wax layers on its surface, which plays a moisture-proof and waterproof role similar to paraffin additives in moisture-proof board. Straw fiber is rich in silica, which is a natural fireproof material, homogeneous porous material and has good sound absorption performance.
Disadvantages: the incense board has high hardness. When it is used as a wardrobe, a slotting worker with poor skills may lead to edge jumping when slotting.
5. plywood.
Plywood is a kind of three-layer or multi-layer plate-like material, which is made of wood segments cut into veneers by rotation or thin boards by wood squares, and then glued with adhesive. Usually, odd veneers are used, and the fiber directions of adjacent veneers are glued vertically to each other.
Advantages: large surface area, strong covering ability, widely used in chemical industry, containers, buildings, metal products, metal structures, etc. It can be cut, bent, stamped and welded at will to make various product parts, which is flexible and convenient to use and plays an extremely important role in automobile, aviation, shipbuilding and tractor manufacturing. Structural parts such as section steel, steel pipe, I-beam and channel steel that can be bent and welded into various complex sections are called "universal steel".
Disadvantages: Due to the large width-thickness ratio and large surface area, the rolling pressure in production is very high, which can reach several million to tens of millions of Newton. Therefore, the rolling mill equipment is complex and huge, and it is very difficult and complicated to control the dimensional accuracy, flatness and surface quality of product width and thickness.
