Aerogel Insulation Refractories in the Ship's Fireproof and Insulation Applications
Background introduction
With China's triumph in the international shipbuilding market, China's shipbuilders have consistently ranked first in the world in shipbuilding completion and order volume since 2012, accounting for 40% of the global market, making them the "world's largest shipbuilding country." Long-term self-driving ship on the water, all parts of self-contained system, structural design and protection requirements have their own characteristics.
As an important means of transport for long-distance bulk cargoes, the structural design of ships is based on the principle of ensuring economy and sailing safety. Due to the limited space of the ship itself, the pipeline equipment and various facilities designed by the ship are relatively compact and the space cost is higher. In this environment, aerogel insulation refractories can effectively save space means more space for operation, living space and maintenance space. At the same time, for fire safety and personal protection considerations, but also requires insulation materials to achieve a high non-flammable standards.
2, Application examples
Vessels can be applied to aerogels insulation refractories more parts, including: fire-resistant partitions, fireproof insulation of cabin construction, high temperature turbine equipment, high temperature pipes, fresh storage, bitumen or LNG carrier insulation hull, and the lifeboat Other special equipment. The insulation and insulation works of pipelines and equipment are similar to the construction of land-based pipelines. Here, only the fire insulation and thermal insulation of the superstructure of a ship is cited.
Ship building fire insulation engineering mainly around the thermal insulation of the cabin and fire-resistant separation. Ship cabin structure is relatively simple and consistent, are generally iron fence and angle iron frame, iron fence wall can be filled inside the ceiling insulation, decorative plate can be installed outside.
3, Effect of validation
According to my company in a 20,000 tons bulk carrier installation experience, 10mm thick aerogel insulation refractories can reach 50mm thickness of rock wool insulation effect. Under direct sunlight in summer, the temperature of the outer wall of the cabin can reach 60 ° C. After being wrapped with the aerogel insulation refractories, the inner wall temperature of the cabin is only 29 ° C, which provides a more comfortable working and living environment for the crew.
