【摘要】 塑料作为人工合成的一种高分子化合物，由于具有优异的物理、化学性能而被广泛应用于人类社会的方方面面，但废弃塑料的回收处理成为当今世界的一大难题。文章提出将废弃的餐盒盖和矿泉水瓶作为燃烧热实验材料，并探讨了该类塑料作为实验材料的可行性及其热能回收再利用的可能性。该实验绿色、价廉、安全可靠，同时贴近生活，能引发学生对环保、能源等社会热点问题的关注。更多还原

【Abstract】 As a synthetic polymer compound, plastics are widely used in all aspects of human society because of its excellent physical and chemical properties. However, the recycling of waste plastics has become a difficult problem in the world. In this paper, the discarded lunch box cover and mineral water bottle were used as experimental materials of combustion heat. The feasibility of this kind of plastics as experimental materials and the possibility of heat reutilization were also discussed. This experiment is green, cheap, safe and close to life. It can also guide students to pay attention to social hot issues, such as environmental protection and energy.更多还原
