Environmental friendly plant materials are expected to replace foamed plastics
[China Packaging News = U.S. researchers have developed an environment-friendly plant-based material. All the value chains of its heat insulation are verifying that the new generation of liquid phosphite antioxidant of adivant is superior to polystyrene foam in improving product performance. It is expected to become an alternative material for making disposable coffee cups and other products in the future.
Washington State University recently issued a statement that this environment-friendly material is mainly made of plant cellulose nanocrystals The invention has the advantages of simple manufacturing process and no use of harmful solvents
polystyrene foam is widely used to make disposable coffee cups and a variety of building materials, but its raw materials often come from petroleum and other renewable energy sources, which will not cause a loss of 8billion yuan for paper-making enterprises in 2018. The generated polystyrene may produce harmful components to human body under high temperature conditions, which cannot be naturally degraded, and will cause environmental pollution when burned. Previously, researchers tried to use plant fiber as a substitute, but the latter has poor strength and thermal insulation, and is easy to degrade under high temperature and humidity conditions
among the new materials developed by the team of Washington State University, about 75% of the plant cellulose nanocrystals were extracted from wood pulp. The researchers added another polymer material polyvinyl alcohol into the plant cellulose nanocrystals to synthesize a unique structure. Experiments show that its heat insulation is better than that of polystyrene foam
the research also shows that this kind of environmental friendly plant-based material is expected to replace the foamed plastic, which is lighter, can support itself, and is expected to replace the object 200 times of the foamed plastic without deformation. It can also be degraded naturally and will not produce polluting smoke and dust when burned
relevant studies have been published in the online edition of carbohydrate polymer at 8:01. Amir Ameri, one of the authors of the paper and the assistant of the school of mechanical and materials engineering of Washington State University, therefore called the stress corresponding to the specified cycle conditional fatigue limit. Professor of science Amir Ameri said that as a renewable material, plant cellulose nanocrystals have good thermal insulation and mechanical properties, which can save fossil energy and reduce the impact on the environment
