| 摘要 |
The present invention relates to a spreading apparatus and more specifically, to a spreading apparatus for building a secondary barrier inside a tank storing liquefied natural gas (LNG). According to an embodiment, the bonding apparatus includes: exterior heat insulation panels which are successively stacked on top of each other inside the LNG storage tank; a body which is exposed between the secondary barrier and the interior heat insulation panel neighboring the secondary barrier, and which runs on the gap between the secondary barrier and the interior heat insulation panel; a nozzle unit which is installed on the body to discharge adhesives to the secondary barrier; a sheet spreading unit which is installed on the back of the nozzle unit, and which spreads a sheet on the discharged adhesives; and a pressurizer which is installed on the back of the sheet spreading unit, and which pressurizes the sheet, while maintaining the pressurizing width to correspond with the width of the secondary barrier. |
