Description

Technical Field

[0001] The utility model relates to the technical field of hydrophobic coating spraying for LNG gasifiers, in particular to a device for spraying hydrophobic coating for LNG gasifiers. Background Art

[0002] Hydrophobic coating is a new type of coating specially used on liquefied natural gas (LNG) vaporizer equipment. It has unique anti-corrosion function. Hydrophobic coating is a high-efficiency coating developed using a special formula. Its main feature is that it can improve the hydrophobicity of the coating surface to water, which means that the coating can form water droplets when the liquid contacts the coating surface, thereby preventing water from penetrating into the coating and protecting the integrity of the coating. Compared with traditional coatings, LNG vaporizer hydrophobic coating can extend the service life of the coating and reduce maintenance costs. Therefore, before the LNG vaporizer is put into use, it is necessary to spray hydrophobic coating on its surface. However, most spraying devices often have fixed clamping structures, which means that only vaporizers of uniform size can be sprayed, which makes it inconvenient to operate during placement and removal.
