Very Popular Plastic Wood Material
Are wood-plastic materials popular? Some companies that want to invest in wood-plastic materials will be concerned with this topic, so what are the conditions that determine the popularity of Co-Extrusion decking material? Generally, this is closely related to its industrial status, development direction and production technology.
The development direction of wood-plastic materials
Wood – plastic composite material is a new type of environmental – friendly building materials that only appeared in recent years. The raw materials used in wood-plastic products can be used as the base materials of waste plastics, waste wood, agricultural and forest orange sticks and other plant fibres, without any additional harmful ingredients. Moreover, recycling can be called a new product in the true sense of environmental protection, energy saving and renewable resources.
With the improvement of people’s attention to environmental resources, the recycling economic development model centring on the recycling of waste materials and the comprehensive utilization of resources has become the trend of world economic development. The development of recycling technology for resources will have a profound impact on the development of the national economy and the sustainable development of the environment. It is a good project to make wood-plastic composite material by using waste plastic and wood fibre.
The outdoor Co-Extrusion decking will become the future trend, for consumers, wood plastic floor belong to energy efficient and environmentally friendly products, not only can very good control of harmful emissions, will also be able to do ground waterproof and moistureproof effect.
The process flow of wood-plastic materials
Some artificial zeolites can be added to the polymer, the aluminosilicate molecules that trap the powder and absorb odours from the material. Through a large number of crystalline voids in the powder, adsorbents can capture odour-producing organic molecules. Molecular capture adsorbent has been successfully used in polyolefin extrusion pipes, injection and extrusion blow moulding vessels, isolation packaging materials, extrusion packaging and sealing materials. The molecular adsorbent powder can also be used as a dehumidifier to remove moisture from the plastic.
Different size and shape of the product increased the diversity of wood-plastic composites when the material does not require a continuous piece of structures or parts with complex structural design, the wood plastic profile can be by injection moulding or moulding. Processors sometimes face the problem of how to fully mould wood-plastic materials during processing. To solve this problem, they need to reduce the number of wood fillers to increase the fluidity of the melt.
Due to 200°C is wood-plastic composite material processing operating temperature limit, some of the melting point of more than 200 ° C resin, such as PET, cannot be used for wood plastic composite. Water vapour deteriorates the properties of composites and helps to breed microbes, so it must be removed before using wood packing. The wood packing should be dried before processing and forming. Generally, the water and gas content after treatment should be less than 1-2%. The current wood plastic composite processing machinery requirements with feeding equipment, drying equipment, extrusion machinery and moulding equipment, and some necessary downstream equipment such as water cooling tank, traction equipment and cutting equipment, etc.
The industrial status of wood-plastic materials
Natural timber resources are decreasing day by day, but the market demand for wood products is increasing day by day. Huge market demand and technological breakthrough will inevitably expand the market channel of wood-plastic materials. From the perspective of market demand, wooden plastic is most likely to expand in the fields of building materials, outdoor facilities, logistics and transportation, transportation facilities and furniture supplies.
