Develop new uses of waste plastics, reflecting environmental protection and fashion

Recently, American scientists have used waste plastics and wood waste to invent a new method of manufacturing composite wood. This method uses a special molecule that can effectively connect plastics and wood fibers.

Due to the large-scale use of plastic products, the recycling of waste plastics has become the focus of research in the world. Scientists in various countries are researching how to mix plastics with various natural fibers to make new materials because these products will be very flexible and durable. Sex. However, since plastics have oleophilic properties and wood fibers are hydrophilic, how to bind two different types of materials together is technically quite difficult.

According to reports, Mestre and his colleagues at the Mining Technology Research Institute in New Mexico, USA, found that using a specially designed graft copolymer molecule, plastic and wood waste can be effectively bonded. In the experiment, the researchers coated the molecules with a thin strip of wood. The plastic yoghurt bottle was then cut into thin strips and mixed with wooden strips. The mixture was put into a machine for heating and extrusion, and finally a firm sturdiness was obtained. Brown new material. Researchers are currently studying how to further improve the properties of this composite by changing the composition ratio of wood fiber and plastic in the mixture and the temperature adjustment in the heating process in order to realize the industrialization of the packaging material as soon as possible.
