China board trading network news: In 2000, the custom closet began to enter the Chinese market. It has been 17 years since its development. The custom closet industry in China is also growing and mature. Custom closets are also becoming more and more popular among home consumers due to their tailored, fashionable, environmentally friendly, and professional features. With the continuous improvement of living standards, people's pursuit of quality of life is also constantly improving, and the requirements for functional concepts that custom wardrobes give to life are also increasing. This also allows custom wardrobes to change from early functionality to present-day decoration and environmental protection. And other aspects of development. As a custom wardrobe main body - wardrobe plate, but also with the different functions of the custom wardrobe in the constant "upgrade" changes. Wood particle board Solid wood particle board is a plate produced by the process of particleboard and is an "upgraded version" of particle board. The wood particle board is made by cutting cutting materials such as various branches, small diameter wood and fast-growing wood into certain specifications, and then drying, mixing with an aldehyde-free adhesive, hardener, waterproof agent, etc., and pressing them under high temperature and high pressure. A kind of artificial board, because its profile is similar to granular, so called solid wood particle board. Here we come to a detailed analysis of the characteristics of solid wood particle board. Decorative performance Solid wood particle board uses wood scrap as material. Compared with natural wood, the wood particle board has a wider board surface, a flat and smooth surface, no defects such as knots, insect eyes and various irregularities, warping, no cracking, and physical mechanics. High strength, vertical and horizontal strength, sound insulation, mildew proof, heat preservation, etc. Environmental performance The density of solid wood particle board is higher, and the wood fiber particles inside the board are larger. Unlike the fiber of the wood fiber board, which is tiny, the nature of the natural wood substrate is more preserved. The glue content of the wood particle board is generally lower than that of the adhesive. 5%, while MDF contains 7% of plastic, so the environmental performance of solid wood particle board is better than that of MDF. At present, many high-end furniture on the market use E1 wood particle board, which is the highest level of environmental protection standards. Since the wood of this board is treated with high temperature, high pressure, and sterilization, it is not prone to mold and insects. Physical performance The solid wood particle board is a kind of flake with 40mm, 70mm, 5mm wide, 20mm, 0.3mm thick, and 0.7mm thick. It is processed through a special equipment with small diameter material, thinned wood, wood core, board skin, and branch material as raw materials. , Sizing, and special equipment A core-slab that has a surface tension of 3,000 pascals after it is laid diagonally and cross-directionally. After the solid wood particle board treats the flake through an advanced ballistic dryer, the coefficient of expansion is small and the moisture resistance is very good. The flake is implemented with oriented layers and auxiliary equipment, so its internal texture is even, more than ordinary particle board and powder. MDF holding nail force, bending pressure, stability must be strong. Processing performance Solid wood particle board density is greater than usual solid wood, excellent physical and mechanical properties, in the various types of wood-based panels is the closest to natural wood and better than natural wood. Therefore, the processing performance of the wood particle board is very good, and the equipment and methods for processing natural wood can be used for processing. The interior of the wood particle board is in the shape of a cross-staggered grain. The particles are arranged in a certain direction, and its longitudinal bending strength is much larger than the transverse direction. Therefore, the distinctive feature of the wood particle board can be sawing, sanding, planing, drilling, boring, Processing by other means is the best material for the panel furniture industry. use As a new type, high-grade and environmentally friendly substrate, wood particle board is widely used by many European and American countries as furniture manufacturers. At present, well-known furniture makers such as Sofia Wardrobe, Haley-Korean, and European Pai have also started to use this kind of plate in large areas. MDF MDF is also called fiberboard. According to different density, it can be divided into high-density board, medium-density board, and low-density board. Currently, the medium-density board is mainly used in the market, which is what we often say as a fiber board. We carefully analyze the characteristics of MDF: Decorative performance The surface of the MDF is smooth and smooth, and it is easy to be coated and glued. MDF is a beautiful decorative plate. Various veneer, adhesive film, veneer, light metal sheet, melamine board and other materials can be glued on the surface of the density board. Environmental performance MDF is ground into fibers, so its internal structural characteristics have changed, requiring the use of a larger amount of adhesive, and its powdered fibers are difficult to release after they have been compressed. To a certain extent, environmental protection factors cannot be guaranteed. Physical properties MDF, in accordance with the national standard GB11718-89 stipulates: Using wood fiber or other plant fibers as raw materials, applying urea-formaldehyde resin or other adhesives to make plates with a density in the range of 0.50 to 0.88, known as medium and high density fiberboard, abbreviated "Medium fiber board." MDF board has uniform fiber structure and high bonding strength between fibers, so its static bending strength, planar tensile strength, and elastic modulus are good. However, because of the fiber inside the wood, the nail holding force completely changes the structure of the wood, and is slightly inferior to the solid wood particle board, and has high hygroscopicity, water absorption performance, and high thickness expansion rate. Processing performance Because MDF is made of logs or plants ground into fibers, completely changing the structure of the wood, it can be produced in the production process from a few millimeters to tens of millimeters in thickness according to demand. Therefore, MDF can replace any thickness of wood and timber, and With good mechanical processing performance, sawing, drilling, slotting, slitting, sanding and engraving, the edge of the board can be processed in any shape, and the surface after processing is smooth. So although the hardness is slightly worse than the solid wood particle board, MDF is now widely used in the domestic panel home industry. use As the performance of MDF is excellent, and it is an effective way for the comprehensive utilization and reasonable utilization of wood, the production is convenient and the cost is not high. It is one of the current domestic custom closet markets. Multi-layer solid wood board Multi-layer solid wood panels are made of three or more layers of veneers and thin sheets, which are manufactured through high-temperature and high-pressure wood veneers. The main substrate is based on a multi-layer plywood with a criss-cross pattern, supplemented by a macromolecule environmental protection glue, and the surface is made of high-quality wood veneer as a fabric, which is produced through several processes including cold pressing, hot pressing, sanding, and health preservation. . Because the multi-layer solid wood panel is pressed with a uniform plywood, it has small deformation, high strength, good internal quality, good flatness, and strong stability. According to different requirements, it can produce laminates with different thicknesses from 5 to 40mm. The multi-layer solid wood panel also has the characteristics of non-deformation and good performance in regulating indoor temperature and humidity. After the melamine finish, the surface of the board has natural and real wood texture and feel. Environmental protection Multi-layer solid wood panels are used in the pressing process. Because they are veneer-laminated and pressed at high temperature and high pressure, they not only have the advantages of structural stability, non-deformability, but also reduce the use of adhesive glue. Polymer glue is used in the production process. After the high temperature and high pressure, PVC edge sealing, reduce the formaldehyde content, so that the amount of formaldehyde released sheet to environmental protection standards, green. Moisture resistance Multi-layer solid wood panels are made of multi-layered veneers, so their structural stability is very good and they are not easily deformed, so that the solid wood panels are easily deformed due to wet and dry weather in terms of internal stress. Sex and stability are very good. The strength of multi-layer solid wood panels is mainly related to the grass-roots level. Each additional layer has a corresponding increase in its strength. Of course, its cost will increase accordingly. The disadvantage of multi-layer solid wood panels with respect to density boards and the like is that since the production costs are higher than others, their prices are higher than those of other boards. Big core board The commonly known as blockboard blockboard, in some places it is also called plywood, is made by two pieces of veneer between the pressure and splicing wood. The big core board is a wood strip that is processed into a certain size and is made of a splice machine. After the splice, it is made by a cold and hot press machine. Advantages: Daxin board has good nail holding power, high strength, strong quality, sound absorption, heat insulation, etc. The moisture content of blockboard is not high, between 10% and 13%, and the processing is simple. Disadvantages: Large core board uses urea-formaldehyde rubber in a large amount in the production process, and the formaldehyde emission is generally higher. The environmental protection standard is generally low, which is why most large core boards have a pungent taste. In the production process, the big core board not only needs enough space for wood to have sufficient time for adaptable natural drying, but also has to pass the drying kiln for strict drying process control in order to produce a qualified large core board. Because of the high demand for processing sites, most of the large core boards on the market are cutting corners in production. When there are large gaps in the splicing of slats, there is ample space in the interior of the plate, so that the nail holding force is basically not guaranteed; inside the large core board, Veneer is longitudinally spliced, so the vertical bending strength is poor, long-term stress will lead to significant lateral deformation of the plate, plus the veneer material is not the same, the density is not the same, only after a simple drying process, easy to Qi Deformation, distortion of the structure, affect the appearance and effect of use, the surface of the large core board is relatively rough, the need for on-site carpentry reprocessing. Therefore, Daxin is now far from meeting the needs of the Chinese custom closet market. Comprehensive comparison Daxinban's environmental protection, pressure resistance, and stability have been far from meeting the needs of modern consumers. It is a must-have plate. Solid wood multilayer board in environmental protection, stability, pressure resistance is able to meet the needs of the modern custom closet market, but the cost is higher, can not be used as a custom wardrobe plate, can only be used as part of high-end customer needs. Only the MDF and solid wood particle board are relatively suitable for the current development needs of the Chinese wardrobe industry. By contrasting solid wood particle board in physical properties, decorative performance, processing performance, environmental performance, etc. are all better than the MDF, to meet the increasingly demanding needs of modern consumers for custom wardrobe, will certainly be the future use of plate furniture plate The inevitable trend.
