<p>PURPOSE:To facilitate operation of a container, to reduce the increase of a liquid temperature due to heat from a power source, and to reduce the cost of surrounding equipment by a method wherein a material having high emissivity is used for the inner wall of a low temperature liquefied gas container, and emissivity of the inner wall is increased. CONSTITUTION:Structure of the wall of a low temperature liquefied gas lorry vehicle is formed such that a pearlite vacuum heat insulating layer 2 is formed in a steel plate outer wall 1, and a stainless steel plate 3 is attached to an inner wall. A tank wall is formed such that a pearlite vacuum heat insulating layer 2 is formed inside the steel plate outer wall 1, and a membrane 7 is mounted to an aluminum inner wall 6. To increase emissivity, a material, e.g. alumina silica, zirconium silicate, having high emissivity is flame-sprayed to the inner wall or a material on which mechanical surface treatment, e.g. sand blast, or heat treatment, e.g. heating by means of a burner for oxidizing a surface, is applied is used for the inner wall.</p> |
