Abstract

The invention discloses an LNG ship liquid dome region secondary shielding adhesion method. The method comprises the following steps of assigning a pasting region needing to be adhered to a FSB; grinding a stainless steel region in the pasting region; coating glue on the pasting region; and pasting the FSB. The method is simple and convenient, high in adhesion efficiency, can improve the adhesionquality, does not need to consider the protection of secondary shielding in the installation process of stainless steel, and improves the period of liquid dome installation integrity.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a secondary shielding adhesion method in a liquid dome area of ​​an LNG ship. Background technique [0002] Mark 3 membrane enclosure system uses 304L stainless steel arch plate and three-layer composite material (RSB&FSB) as the primary and secondary barrier walls. Since the secondary screen wall is made of non-metallic three-layer composite material, film adhesion technology is introduced. The liquefaction temperature of liquefied natural gas is -163°C. In order to prevent LNG leakage, the quality and integrity of primary and secondary shielding are particularly important. For the leakage point of the corrugated plate on the main layer in the LNG cargo tank, the function of the secondary shielding is to prevent low-temperature embrittlement caused by the direct contact of LNG with the hull, and ensure no leakage for 15 days. [0003] The integrity and sealing...
