Summary
A profession that produces shirasu balloons, a lightweight aggregate, by firing shirasu, which is mainly produced in Kagoshima Prefecture, at high temperatures.
Description
Shirasu balloon manufacturing workers appropriately select, crush, and blend shirasu, which is volcanic ash, shape it into granules using specialized molding machines, and then heat and foam it in high-temperature firing furnaces to produce lightweight aggregate with internal air bubbles. The production process includes raw material adjustment, operation management of molding machines and firing furnaces, cooling and sorting, quality inspection of particle size and specific gravity, and packaging and shipping preparation. They also perform regular inspections and maintenance of mechanical equipment, process improvements, safety and health management, and environmental management to ensure stable quality and improved production efficiency.
Future Outlook
As long as the demand for lightweight aggregates in the construction industry remains stable, steady demand can be expected. With advancements in environmentally friendly concrete and decarbonization technologies, the importance of shirasu balloons as low-carbon materials may increase.
