LPG CARGO OF LIQUEFIED PETROLEUM GAS CARRIER AND HIGH-PERFORMANCE INSULATION AND STRUCTURAL COMPONENTS THEREOF

摘要

The present invention relates to a medium-to-large LPG carrier cargo hold and a high-performance insulating structural material to which the high-performance insulating structure is applied, and the high-performance insulating structural material of the present invention is a non-foamable polyurethane on the inner side of the lower plate, the frame and the upper plate in the metal box space. Since it adheres completely in close contact with each other, such a strong adhesive structure provides structural performance, as well as non-foamable polyurethane is wrapped around the heat insulating material by airtight adhesion to protect gas from entering and exiting. There is an effect that can maintain the insulation performance as it is without. In addition, since the LPG carrier cargo hold to which the high-performance insulation structure of the present invention is applied is not a stand-alone tank insertion method, but is directly installed on the hull, a huge rectangular space generated between the existing stand-alone tank and the hull can be eliminated. Significantly increases.
