Abstract
The invention relates to a sealing method for butt joint and angle joint of steel-aluminum composite material transition connectors and belongs to the technical field of ship material connection. The method mainly comprises the steps that a gap of 2-3 mm should be reserved in installation at the butt joint and angle joint position of the steel-aluminum composite material transition connectors, a lead bar is embedded into the gap for butt joint and angle joint of the steel-aluminum composite material transition connectors, and the gap is sealed through the malleability of metal; a space area is defined by a steel (aluminum) surrounding plate and an installation base plate in a welding mode at the position, away from the connectors by 75-85 mm, on the gap for butt joint and angle joint of the steel-aluminum composite material transition connectors, and then PC120 primer and PLEXUS MA425 structural adhesives are poured into the space area. The sealing method effectively achieves the sealing performance of butt joint and angle joint of the steel-aluminum composite material transition connectors at the normal temperature, and high-quality sealing for butt joint and angle joint of the steel-aluminum composite material transition connectors is achieved.
Description
Technical field
The present invention relates to the encapsulating method of the docking of a kind of steel-aluminum composite material transit joint and fillet joint, belong to shipbuilding materials interconnection technique field.
Background technique
The docking of steel-aluminum composite material transit joint and fillet joint are the pressure produced by blast, metals different with two kinds, aluminium for steel is linked together, and by adopting the welding technique of steel and aluminum material between steel and aluminium respectively, steel and aluminium are linked together by this compound transition joint, but to the docking between steel-aluminum composite material joint and corner connection sealing, existing welding method can not adapt to well, the docking of material and corner connection welding between steel-aluminum composite material transit joint, the solution that the sealing of its docking and corner connection has never had.
Summary of the invention
The object of the invention is cementability and the chemical stability of ductility and the structure glue excellence utilizing metallic lead good, make the docking of steel-aluminum composite material transit joint and fillet joint sealing be solved preferably at normal temperatures.
In order to reach foregoing invention object, steel-aluminum composite material transit joint of the present invention and fillet joint encapsulating method as follows:
(1) at the docking of steel-aluminum composite material transit joint and fillet joint place, about 2-3mm gap during installation, is left;
(2) embed leads in the docking of steel-aluminum composite material transit joint or position, fillet joint gap, the ductility utilizing metallic lead good makes position, gap be sealed;
(3) after carrying out initial survey to above-mentioned joint tighness, at the docking of steel-aluminum composite material transit joint or position, fillet joint gap, apart from area of space cast PC120 primer and the PLEXUS MA425 structure glue at joint 75-80mm place.
Steel-aluminum composite material transit joint of the present invention and fillet joint encapsulating method, efficiently solve the sealing of the docking of steel-aluminum composite material transit joint and fillet joint under normal temperature, utilize plumbous fillibility, the high-adhesive-strength of structure glue, achieves the high quality seal of the docking of steel-aluminum composite material transit joint and fillet joint.
Embodiment
The present embodiment is the encapsulating method with the docking of the steel-aluminum composite material transit joint of certain type ship cargo tank and fillet joint, and concrete encapsulating method process is as follows:
1, seal process
1) process, before sealing
At the docking of steel-aluminum composite material transit joint and fillet joint place, about 2-3mm gap should be left during installation, then at steel-aluminum composite material transit joint joint and fillet joint gap location, and the deck surface at periphery injecting glue place, gap, carry out the process of deck surface roughness with stainless steel motor wire brush, and blow down dust, the moisture content of gap location with pressurized air; Remove if any greasy dirt application detergent, ensure that play movement and construction part are clean, dry;
2), with the filling of leads
Embed leads in the docking of steel-aluminum composite material transit joint and position, fillet joint gap, by the machinery type such as hammering or extruding, make leads be full of position, gap, and fit tightly with composite material section, utilize the ductility of metal that position, gap is sealed;
3), hydraulic pressure is poured water inspection
After each play movement of cargo tank is by above-mentioned requirements sealing, make water filling test in cabin, height of pouring water pushes up above 1.8m to cabin;
4), PLEXUS MA425 structure glue fills
Inside and outside joint area within the scope of 200mm, carry out cleaning and do roughness process; Again at the docking of steel-aluminum composite material transit joint and position, fillet joint gap, apart from joint 75-85mm place, high with 4 × 60mm() steel (aluminium) coaming plate, after surrounding an area of space with installation base plate welding, again in area of space cast PC120 primer and PLEXUS MA425 structure glue, namely complete seal process;
2, cargo tank observes inspection after refueling
After cargo tank fills it up with fuel oil, regularly carry out observation inspection every day, continuous time should be no less than 10 days, and loseing seepage, to be airtight quality good.
In addition to the implementation, the present invention can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
Claims (1)
1. an encapsulating method for the docking of steel-aluminum composite material transit joint and fillet joint, is characterized in that its encapsulating method is as follows:
(1) at the docking of steel-aluminum composite material transit joint and fillet joint place, 2-3mm gap during installation, is left;
(2) leads is embedded in the docking of steel-aluminum composite material transit joint or position, fillet joint gap;
(3) at the docking of steel-aluminum composite material transit joint or position, fillet joint gap, apart from area of space cast PC120 primer and the PLEXUS MA425 structure glue at joint 75-85mm place.
