초록
Reinforced plastics containing waste polypropylene, waste coal, and fly ash were manufactured, and the usefulness of reinforcing agents such as waste coal and fly ash was investigated from the physical properties of the manufactured reinforced plastics. The physical properties (tensile strength, tensile elongation, flexural strength, impact strength, and hardness) of the manufactured reinforced plastic using waste coal or fly ash as the reinforcing agent were superior to those of general particle-reinforced plastics but inferior to those of fiberreinforced plastics. When increasing amounts of reinforcing agents were added, the physical properties of the reinforced plastic increased proportionally. In general, the efficiency of fly ash as a reinforcing agent is better than that of coal waste. Using a combination of the two reinforcing agents, improved the physical properties of reinforced plastic compared to those of the individual agents because of the homogeneity of the mixture. Because coal waste and fly ash may contain various harmful ingredients, their elution will be of concern in long term. However, harmful components such as cadmium, chromium, mercury, lead, and organic bromine were not detected in these wastes. The manufactured reinforced plastics investigated in this work may be used to replace the concrete rain storage systems, which have a high construction cost, weak shock-resistance, and are difficult to manage. Moreover environmental problems due to waste coal and fly ash can be minimized if they are reused as reinforcing agents.
Abstract
Reinforced plastics containing waste polypropylene, waste coal, and fly ash were manufactured, and the usefulness of reinforcing agents such as waste coal and fly ash was investigated from the physical properties of the manufactured reinforced plastics. The physical properties (tensile strength, tensile elongation, flexural strength, impact strength, and hardness) of the manufactured reinforced plastic using waste coal or fly ash as the reinforcing agent were superior to those of general particle-reinforced plastics but inferior to those of fiberreinforced plastics. When increasing amounts of reinforcing agents were added, the physical properties of the reinforced plastic increased proportionally. In general, the efficiency of fly ash as a reinforcing agent is better than that of coal waste. Using a combination of the two reinforcing agents, improved the physical properties of reinforced plastic compared to those of the individual agents because of the homogeneity of the mixture. Because coal waste and fly ash may contain various harmful ingredients, their elution will be of concern in long term. However, harmful components such as cadmium, chromium, mercury, lead, and organic bromine were not detected in these wastes. The manufactured reinforced plastics investigated in this work may be used to replace the concrete rain storage systems, which have a high construction cost, weak shock-resistance, and are difficult to manage.
