Wood plastic compos ites at home and abroad is also called: plastic wood, wood, wood technology, environmental protection, renewable wood plastic wood or poly wood, the standard English Name: Wood & Biofiber Plastic Composites, the industry known as WPC. Is with sawdust, straw, bamboo shavings, Gu Kang, peanut shell, cotton stalk and other primary biomass materials as the main raw materials, filled with the features of polymer chemistry principle and interface of plastic, plastic base material is mixed with a certain proportion, a reversible recycling, morphology varied basic material after special treatment processing. It not only keeps the appearance and feel of solid wood flooring, but also has good moisture and water resistance, acid and alkali resistance, antifungal, antistatic, insect resistant and boring performance, and wood plastic products have high fire resistance, pollution-free, harmless and recyclable.
The overseas wood and plastic industry is represented by North America. North America is currently the world's fastest growing and largest consumption area of wood plastic composites. It is mainly used for rough outdoor architecture, and its wood and plastic products and their manufacturing technology are not very sophisticated. Over the past 10 years, the growth rate of the wood plastic market in the United States has been maintained at over 10%, especially in the past 5 years. Especially in recent 5 years, the output and sales volume of wood plastic materials is about 700 thousand tons. Now, there are about 50 wood and plastic enterprises in the United States, and a complete industrial chain has been formed. Its characteristics are large scale and high output, and the annual output is generally over 10000 tons.
China's wood plastic industry is a very young industry. Its growth has lasted for 10 years. No matter what way it looks, Shang Xianzhi is Nen. Compared with the North American market, the growth of wood plastic composites and finished products has considerable space. At present, there are several types of structure, decoration, packaging and other special domestic research and development of wood plastic materials, including a series of wire, profiles, sheet and profile etc., its scope can almost cover all fields of use wood, plastic, steel, Aluminum Alloy and other similar composite materials now. The scope of application of wood plastic materials has been involved include: dado, window, door, floor, corridor, partition, ceiling, guardrail, fence, edge, Zhanqiao, bath room, door and window sets, rest kiosk, garage, deck, furniture accessories, water channels, open-air seats, stairs, open platform, container
Puban, stadium seats, light soundproof walls, multifunctional wall partition, highway soundproof walls, and began to seep into the building, decoration, packaging, logistics, gardens, municipal, environmental protection and other industries. The design and manufacture of domestic wood plastic composites have reached the international advanced level, and many products have been exported to foreign countries.
But at present, the national standards of wood plastic composites are still missing. Most of the domestic standards for wood plastic pallets are mostly based on wood products standards, and lack of wood plastic materials. The problem of quality and safety of wood plastic products is also getting more and more attention. SGS can provide testing services for wood plastic materials. Most of the tests can only be based on foreign standards and select specialized agencies for the inspection of products. The most commonly used testing standards are ASTM D7031, ASTM D7032, CEN TS 15534-3 and other standards. At present, the main testing items are fire resistance, UV resistance test, mechanical properties, wear resistance test, water absorption and thickness change rate, freeze-thaw test, creep performance, formaldehyde emission, environmental protection and so on.
