Today's society, plastic and wood are all essential for building and furnishing materials, they are its unique properties, in many applications, playing an irreplaceable role in socialist construction and the people live and work made a great contribution.
In recent years, doors and windows in the building industry, wood plastic profile and has been in use among the competition. When high-quality wood products more and more people favored wood products are increasingly popular in the city when the rates of deforestation, faster and faster, as the depletion of natural resources crisis about to wake-up call. Fortunately, the plastic profile industry, largely replaced the wooden doors and windows, to some extent alleviate the ecological crisis, but still poses some unavoidable defects, such as texture and color of plastic profiles and so can not beyond the wood products, the cost is naturally greatly reduced. Is it possible to combine plastic and wood to produce a cost-effective and environmentally friendly, practical and high-quality products to replace plastic or wood it?
Proved to be possible. A few years ago, international experts think of this problem and have to pay the actual action has been fairly impressive results. For example, a few years ago in the plastic profiles and applications involved in an earlier study of European countries have pioneered the combination of wood fiber and plastic composite profiles made of, and has been successfully achieved in many aspects of the application. It is said that in recent years, a Singapore-based company has also succeeded in filling the volume of wood fiber increased by 50%, while the intensity of manufactured windows and doors also meet the relevant standards. Described above, wood-plastic composite profile of the research has achieved real results, and clinical application of its production out of the more important step. Wood-plastic composite profile production although a reality, but it really can achieve the functions of wood and plastic and can eventually replace them? I am afraid this is a lot of people's questions. Well, now I am through with the wood-plastic composite extrusion products, plastic products and wood products, the comparison function to answer this question, we may be able to after reading some confusion.
Products from wood and wood composite extrusion comparisons, wood-plastic composite materials manufactured by the extrusion process resembles the look and texture of wood, and wood and has the same processing performance, construction performance. Products between the density of 600 ~ 1000kg/m3, according to the amount of wood fiber and foam padding the rate of different, generally around 600 ~ 800kg/m3, and wood is very close. Moisture content of about 2%, while the wood moisture content of 12% ~ 13%, compared with the wood plastic composite profile has better anti-water, anti-corrosion and other functions, and there is no natural wood defects, such as cracking, warping, scars knot, obvious color and so on. We also know that wooden doors and windows in addition to mechanical, physical and chemical damage, there is a caused by joint weakness, that is, pest damage, such as termites, beetles and other pests, and wood-plastic composite profiles with a variety of chemical agents, can resist pests. In addition, extrusion products section design flexibility to design decorative, decorative structures and functional structure, functional structure and wood products, and decorative structures are often limited by the processing method, a lot of decorative effect is difficult to achieve. Obviously, these are superior to wood-plastic composite products, wood products out of the place, and almost without exception, and the Department.
From wood plastic composite profile extrusion products and more general point of view, wood plastic composite profiles with the most common benefits, such as flame-retardant, anti-aging, but also has an ordinary plastic profiles can not replace other advantages, such as color, texture and light weight quality performance, can be nailed, drilled, sawn, planed to be on the paint, bonding and other processing performance. However, the wood-plastic composite extrusion products, welding performance is poor, largely unsuitable welding, therefore, the use of bolted doors and windows to form the assembly, which is a big shortage. However, the use of wood-plastic composite extrusion products in the field of construction, transportation and installation of doors and windows to give to bring a lot of convenience, can be considered to some extent make up for the shortcomings it.
From the above two groups, we can see wood and wood-plastic composite profiles with plastics (excluding special plastic) and most of the performance, and is able to both set in one of the main performance, but also has its own unique features The most important thing is to use wood-plastic composite profiles can significantly save energy and reduce the loss of non-renewable resources, maintain natural ecological balance, power can be described as the best thing. Having said that, since the wood-plastic composite profiles with wood and plastic profiles and incomparable advantages, but also energy saving, environmental protection, is bound to have broad application prospects. We can believe that, with the wood-plastic composite extrusion production technology to further improve products and production processes of large-scale promotion of wood-plastic composite profile will be able to gradually replace the plastic and wood products, market position and become the unrivaled architectural decoration The NO1!
