Face combines accompanying drawing and is described in detail embodiments of the invention.
In describing the invention, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear",
The orientation of the instruction such as "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " or position relationship are for based on accompanying drawing institute
The orientation shown or position relationship, be for only for ease of and describe the present invention and simplify description rather than instruction or the dress of hint indication
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that protect the present invention
The restriction of scope.
Fig. 1 is the schematic flow sheet of fuel tanker lid encapsulating method according to an embodiment of the invention.
Fuel tanker lid encapsulating method as shown in Figure 1 includes: described fuel tanker lid encapsulating method includes: will fly
Sump lid is smeared and is smeared the first bonding primary coat on anticorrosion priming paint, and the lid after smearing anticorrosion priming paint and dry,
And the fuel tanker lid brushing polysulfide sealant after drying；The aluminium alloy mouth frame of fuel tanker is smeared anticorrosion priming paint,
And brush the second bonding primary coat at the gluing position of the aluminium alloy mouth frame smearing anticorrosion priming paint, and dry；Scribbling second
