The rise of wood-plastic is the inevitable technology, not the commercial accident.
Wood-Plastic Composites (WPC) is a new type of composite material that has been booming in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesives. The above plant fibers are mixed into new wood materials, and then subjected to extrusion, molding, injection molding and other plastic processing processes to produce sheets or profiles. Mainly used in building materials, furniture, logistics and packaging industries. A hot-extruded sheet of plastic and wood powder mixed in a certain ratio is called an extruded wood-plastic composite sheet.
Composite material · wood plastic
First, the wood-plastic composite material is made of PP/PE/PVC/PS/ABS general-purpose resin as the base material, wood powder, WPC powder supplemented with corresponding additives, and extruded, injection-molded, molded and other forming processes to produce profiles, plates and sheets. The products used in decoration, garden landscape, and packaging to replace wood are called wood-plastic composite materials.
Second, why should we vigorously develop wood-plastic composite materials?
1. Circular economy: Wood-plastic materials can be recycled, that is, they can be crushed and then used after being used for many years, in line with the national circular economy policy.
2, environmental protection: wood plastic materials themselves are environmentally friendly (because the use of plastic, WPC powder wood, additives are environmentally friendly), and the use of plastic and WPC powder, wood powder, to reduce the impact of plastic burning on the environment; in line with environmental protection Policy.
3, energy saving: the use of wood plastic materials instead of wood, plastics, steel, can reduce energy consumption and achieve energy-saving effects. The wood-plastic material itself is insulated and applied to the building, which can significantly save energy. Meet the national energy conservation requirements.
4, energy saving and emission reduction: the use of wood-plastic materials, reduce the use of wood, reduce deforestation, so that the forest absorbs carbon dioxide, so that carbon dioxide emissions are reduced. In line with national energy conservation and emission reduction policies.
Third, the molding process and equipment formula of wood-plastic products The molding methods of wood-plastic composite materials mainly include compression molding, extrusion molding, injection molding, and the like. Among them, the extrusion molding has large output, continuous production and high efficiency, and is suitable for the production of various profiles and plates. Therefore, it is favored by many companies.
In recent years, with the continuous advancement of China's new urbanization construction, protecting the environment, promoting the healthy and high-speed development of the landscaping industry, and adhering to the path of intensive, energy-saving and ecological sustainable development has become a major and urgent task.
In order to meet the needs of new urbanization construction, green and new composite materials are gradually replacing the original non-recyclable materials. Because of the various characteristics of wood-plastic, its application is extensive, and the importance of green wood-plastic wood in market applications is becoming increasingly apparent.
For outdoor plank roads
Wood plastic can be used for landscape revetment in wet and multi-water environments due to its advantages of waterproof, moisture-proof, anti-corrosion, anti-mite, insect-proof, non-deformable and easy to maintain. Wood-plastic composites do not require routine maintenance, have a longer service life than ordinary wood, and satisfy the people's pursuit of nature with the visual effects of their simulated logs.
For garden landscape floors
In the outdoor platforms such as garden landscapes and villas, the wood-plastic flooring not only shows the affinity of natural wood, but also its rich colors can be coordinated with the landscape plants to meet the landscape designer's pursuit of innovation and beauty.
For hydrophilic platforms
Wood-plastic composite materials in the park, lakes, wetlands and other water-based attractions, combined with landscape pontoons, water trails, viewing corridors and other design, more ecological display of the natural attributes of the hydrophilic platform.
For park leisure benches
With its unique visual effects and ever-changing design, the wood-plastic leisure bench has gradually become a beautiful landscape in the urban garden landscape. In addition to bringing convenience to people, it also meets the needs of new urbanization construction with low carbon and environmental protection.
For flower stands, tree pools
In the construction of modern garden landscapes, wood-plastic flower stands and tree ponds can better show the effect of the original ecological natural landscape. Wood-plastics can be decorated with gardens with its rich colors, which makes people pleasing to the eye.
Wood plastic relies on its own powerful features: high material density, high strength, long service life, sun protection, anti-corrosion, and no deformation. The older the more, the more popular the group is. Such a black horse rises. It is the inevitable phenomenon that technology has changed, and this inevitable phenomenon has made our environment better and better. It is the accidental success of commercial operation that cannot be brought about!
