AUXILIARY SECONDARY BARRIER, LNG TANK COMPRISING THE SAME AND MANUFACTURING METHOD THEREOF CAPABLE OF EASILY ATTACHING AN AUXILIARY SECONDARY BARRIER TO A MAIN SECONDARY BARRIER WITHOUT AN EXTERNAL HEAT SOURCE BY ADHERING MAIN AND AUXILIARY SECONDARY BARRIERS WITH A FIRST HEATING MEMBER OF THE AUXILIARY SECONDARY BARRIER

摘要

PURPOSE: An auxiliary secondary barrier, an LNG tank comprising the same and a manufacturing method thereof are provided to enhance adhesion to a main secondary barrier by uniformly hardening an auxiliary secondary barrier by uniformly supplying heat to all surfaces of the auxiliary secondary barrier with a first heating member.;CONSTITUTION: An auxiliary secondary barrier(222) comprises a first heating member(51), first and second metallic foil layers(61,63), and a glass-fiber layer(62). The first metallic foil layer is formed on the first heating member. The glass-fiber layer is formed on the first metallic foil layer. The second metallic foil layer is formed on the glass fiber layer. The first heating member hardens a first adhering layer(10) adjacent to the first metallic foil layer.;COPYRIGHT KIPO 2012
