Waste plastic and waste wood fiber composite materials and wood-plastic tray production technology

Due to the presence of worms in the wood packaging of China's exported goods, the U.S. and Canadian governments respectively decided to handle the wooden packaging and wooden bedding materials of Chinese cargo that departed on December 17, 1998 and January 4, 1999. Otherwise, the entry of goods will be prohibited. The United Kingdom also announced that on February 1, 1999, new quarantine standards will be imposed on all wood packaging from China. The EU is also preparing to take such measures to prevent the entry of the worm. The implementation of new technical standards and technical measures is a means for developing countries to implement trade protection. With the WTO's restriction on tariff barriers, it is not new for developed countries to use technical standards and technical measures to implement trade protection policies on their products. According to industry insiders, the developed countries have adopted new quarantine standards for the use of wooden packaging and wooden bedding materials for export goods in China, which should be taken seriously. Reforming China’s export packaging materials has no time to delay. According to the development trend of international popular packaging, accelerating the application and development of new packaging materials can not only reduce the cost of China's export goods, but also help protect our limited natural resources.

From an economic point of view, since the United States and Canada require the fumigation of the wood packaging of China's export products, the impact on China’s exports will reach US$30 billion. Moreover, the cost and time of fumigation treatment is also considerable. It takes at least 16 hours and about 300 RMB per fumigation to process one container. Taking China's annual exports of 5 million containers, the domestic cost will exceed 1.5 billion yuan and the processing time will be 100 million hours. In the United States or Canada, the cost is more than 2 times higher than in China.

From the point of view of the protection of timber resources, at present, in North America, the largest consumption of hardwood is the production of pallets, accounting for 40% of hardwood output, and the annual consumption of 24 million cubic meters; China's current production of wood pallets up to 50 million, timber consumption Amount of 2.5 million cubic meters. Since only one tree can be made into 6 pallets, the 6 pallets will be scrapped for up to two years. At the same time, with the increase of exports, the development of wooden packaging boxes in China is very rapid, especially for the export of mechanical and electrical products, and the consumption is very large. In addition, the catastrophic floods that occurred in China in 1998 caused huge economic losses. An important cause of flooding was long-term and massive loss of water and soil caused by deforestation. On the other hand, experts predict that China’s demand for wood by the year 2000 will exceed 1 Billions of cubic meters, and the amount of timber supply at that time is only 60 million cubic meters. Therefore, in order to protect the limited timber resources, it is necessary to find suitable production trays for wood substitutes. Therefore, a new type of green and environmentally friendly material, wood-plastic composite material, has appeared in the international and domestic markets.

This new type of material is used to add waste plastics and used wood, including sawdust, wood twigs, oyster hulls, and peanut hulls, in a certain proportion, with special adhesives, processed into high temperature and high pressure to form structural sections, and then assembled into trays. Or packing box. The result of use shows that this is a new material with good performance, economical cost, and environmental protection. This wood-plastic composite material can not only be used as an alternative to wood for transporting wooden packaging materials and bedding materials, but also can be used as a wood substitute in furniture, construction, industry, vehicles, ships, packaging and transportation and other fields.

In addition, in order to solve the contradiction between supply and demand of wood in China, an important way out is to increase the utilization of wood. At present, the comprehensive utilization rate of wood in China is only 63%, which is far below the level of developed countries. Due to its raw materials, mainly waste wood fiber and waste plastics, this material can be used as an economically applicable technology to make high value-added wood substitutes from waste materials that cannot yet be scaled in China, and to protect our forest resources. Reducing environmental pollution also has very important significance. It can be foreseen that with the implementation of the ban on the United States and Canada, the new material will be put into production as soon as possible in China, which will provide a comprehensive, one-on-one solution to the three major problems of China's current shipment of wood packaging, timber shortage and "white pollution." A lot of solutions.

Pellet Grill

A pellet grill is a type of outdoor cooking appliance that uses compressed wood pellets as fuel to cook food. The pellets are fed into a hopper, which then moves them into a burn pot where they are ignited by an electric heating element. The heat generated by the burning pellets is used to cook the food on the grill grates. Pellet grills typically have digital temperature control systems that allow for precise temperature regulation and cooking time. They are known for producing a unique smoky flavor and are popular among barbecue enthusiasts.
