Fig. 1 is the position of the corrosion-inhibiting coating in pipeline of the utility model.
Fig. 2 is the ship displacement pipeline transverse cross-sectional view of the utility model.
Fig. 3 is the ship displacement pipeline longitudinal sectional drawing of the utility model.
Specific implementation mode
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in Figs. 1-3, the ship displacement pipeline composite anti-corrosive coating 2 of the utility model is tightly attached to the outer surface of pipeline 1.
It is equipped with prime coat 210 successively from inside to outside, is close to the setting of ship displacement pipeline external surface, thickness is 45-65 μm；Layers of copper 220,
It is arranged in 210 outer surface of the prime coat, and thickness is 90-150 μm；Phosphate coating 230 is arranged outside the copper alloy 220
Surface, thickness are 8-15 μm；Ceramic coating 240, in 230 outer surface of the phosphate coating, thickness is 21-30 μm for setting；Low table
Face energy coating 250, in outermost layer, thickness is 90-100 μm for setting.
50 μm of 210 thickness of prime coat, it is (C that the prime coat, which selects acrylic resin, molecular formula,3H4O2)10, to metal knot
The ship displacement pipeline of structure has the anti-corrosive properties for enhancing coating compared with high adhesion force.
220 preferred albata layer of layers of copper, thickness are 100 μm.The copper-nickel alloy-layer 220 has higher resistance in the seawater
Corrosive nature.The content of nickel is 5% in layers of copper 220.Layers of copper 220 can significantly improve intensity, corrosion resistance, hardness, resistance and thermoelectricity
Property, and reduce temperature coefficient of resistivity is excellent corrosion-resistant material.
230 preferred ferric phosphate Fe of the phosphate coating2(SO4)3, thickness is 10 μm, and the phosphate coating can increase layers of copper and ceramics
The adhesive force of layer, keeps coating closer.
Preferably, the ceramic coating 240 selects bromo propanepoxy resin C21H20Br4O4, thickness is 95 μ
m.Ceramic coating 240 has good sea water resistance energy, wear-resisting property, heat resistance and solvent resistance.
Preferably, the low surface energy coat 250 selects perfluoro acid fat (CH2)2(CF2)10, it is 95 μm,
The overall surface energy that corrosion-inhibiting coating can be reduced keeps the cleannes of coating surface to reduce the wellability and frictional force of seawater, drop
Low-corrosiveness.
The manufacturing process of the ship displacement pipeline composite anti-corrosive coating of seawater corrosion resistance is：The outer surface surface of pipeline 1
Activating agent oil removing, pickling, is washed at washing again, spray-applied primer layer 210 after drying, and forming cupro-nickel by diffusion after dry closes
Layer gold 220 then carries out phosphorating treatment, drying, and in its surface shape light-iron phosphating layer 230, ceramics are applied in 230 outer surface of phosphate coating

Using electrochemical alternate impedance spectrum (ESI) technology to the composite anti-corrosive coating of the utility model in briny environment
It is studied using the failure procedure at initial stage, while the absorption problem of moisture and the diffusion system in the process is analyzed using capacitance method
Number detects the anti-corrosion effect of this composite anti-corrosive coating with this, it is found that coating resistance is with smaller rate 5381 after 120 hours
Ω/h declines, and moisture absorption is also the process to be slowly increased, and diffusion coefficient is 1 × 10-10cm2·s-1.The rate is much smaller than
It is not added with the experimental data of corrosion-inhibiting coating, and respectively lower than the numerical value of metal coating 10% and 12%.It can thus be appreciated that this is compound anti-
Rotten coating has excellent anti-corrosion effect.
