Since the 1980s, the industry has begun to pay attention to plastic-wood composite materials and apply them in the fields of transportation, building materials and furniture. Subsequently, wood-plastic composite materials are gradually applied to the manufacture of building partitions, pallets, floors and decorative panels. in. In recent years, under the in-depth publicity, people have begun to realize the advantages of plastic-wood composite materials and have shown good development prospects in the field of furniture manufacturing.
Advantages of wood-plastic composites in the field of furniture manufacturing
The toughness and strength of the material will directly affect the quality of the furniture. Under the improvement of the formula, the impact properties and bending properties of the wood-plastic composite material have been significantly improved. The wood-plastic composite material made of glass fiber and sisal fiber has better mechanical properties than traditional materials. Of course, the performance of plastic-wood composites will also be affected by the type of plastics and fillers. Different raw material formulations will have large differences in performance and need to be arranged according to specific application requirements. Furniture is an indispensable item in people's lives. It must have good surface properties and a beautiful appearance. Therefore, the surface properties of wood-plastic composite materials will affect the manufacturing grade of furniture and directly reflect the market price. aspect. The surface properties of wood-plastic furniture are mainly determined by color, luster, texture, touch and texture. Through molding and extrusion, the ideal surface properties can be achieved.
Unlike daily necessities, clothing, and food, furniture is accompanied by very long periods of use and slow pace of replacement. Therefore, people have very high requirements for the durability and corrosion resistance of furniture. Wood-plastic composites have high-quality anti-mite, anti-corrosion, anti-drying, flame retardant and waterproof properties. Researchers are conducting research on the wear resistance, thermal stability and creep of materials, and have achieved preliminary results.
For the furniture of the bathroom, dining room and kitchen, not only should it be beautiful and beautiful, but also have the functions of antibacterial and antibacterial. The wood-plastic composite has good antibacterial and antibacterial properties. In recent years, research on the antibacterial problem of plastic-wood composites has been Beginning with broad-spectrum antibacterial to anti-pathogenic stages. In recent years, plastic wood furniture has begun to develop in more fields, and gradually reflects the artistic style of the wood-plastic composite material itself. Designers have found that small-sized homes need simple, affordable, safe and comfortable furniture, and plastic-wood composite materials can meet the needs of small-sized homes.
Application of wood-plastic composite materials in the field of furniture manufacturing
According to the structure, common wooden houses have panel furniture, frame furniture, shaped furniture, and curved wood furniture. Plastic wood panels can be used as framed furniture panels and panels, or they can be made into panel furniture. Bottom plate, top plate, partition plate, side plate, etc. Since the 1990s, people began to use the die-casting method to manufacture prefabricated parts, and set up a mesh layer. Under the development of plastic wood extrusion technology, researchers will use twin-screw extruders and single-screw extruders. The combination of sheet and mold has successfully produced plastic-wood furniture panels. With the development of paintable wood-plastic furniture technology and imitation marble plate technology, the wood-plastic surface decoration technology has ushered in a better development prospect. Compared with traditional materials, wood-based materials do not release harmful substances, which meets people's requirements for health and environmental protection.
At present, the wood-plastic profiles have been widely used in the manufacture of furniture trims, legs and door frames, and the production efficiency is very high. The profile molds can be modified to produce various types of furniture profiles. At the stage, the research on the manufacturing technology of plastic wood profiles mainly focuses on mold size, formulation improvement, cavity design, material rheology, process parameters and so on. In order to improve the durability and mechanical properties of the material, wood-coated solid wood and embedded ribs can be used, and 3D printing technology, engraving technology and laser sintering technology are used to effectively improve the appearance of the furniture decoration.
Regarding the assembly and connection problems in plastic wood furniture, it has always been the focus of research. In order to improve the durability of furniture, it is necessary to consider the firmness and disassembly of the furniture. When connecting, it is necessary to pay attention not only to the function of the furniture, the force and the place of use, but also to the creep properties, viscoelasticity and nail holding force of the material. Different types of plastic-wood composites have significant differences in their mechanical properties. It is necessary to select reasonable structural treatment and connection methods according to the type of materials. In order to ensure the assembly effect of plastic wood furniture, special joints and screws need to be applied. At this stage, research on the connection technology of plastic wood profiles needs to be improved.
Plastic-wood composite materials are the focus of future research, and they are applied in the field of furniture manufacturing, which promotes the further development of furniture manufacturing industry. With the excellent performance of plastic-wood furniture, the market puts higher demands on plastic-wood furniture. How to realize "lightweight and high strength" of its components is becoming a problem that material researchers and designers need to think about and solve.
