3.5 parts of aqua, ammonium hydroxide 0.5 divide 12 parts of curing agent, 3 parts of m-phenylene diamine (MPD), 6 parts of molybdenum disulfide, 4 parts of polyamide 612, when use voluntarily
Preparation is carried out to reuse；The insulating layer is wrapped in outside corrosion-resistant coating, heat-insulation and heat-preservation；The protective layer is flexibility, is had certain
Elasticity can be tightly wrapped in outside insulating layer, anti-mechanical collision；The radiation protective layer is aluminium foil uvioresistant anti-corrosion Cold winding band, tool
There are high radiation preventing performance and very strong cohesive force, is placed directly against on protective layer；The outer corrosion-resistant coating is located at outside radiation protective layer, described
Outer corrosion-resistant coating is the transparent epoxy resin that two component of a, b mixes that solidification is formed jointly, and light can pass through, to prevent radiation protection
Layer is corroded by the external world；The bed course is flexibility, when pipeline and other objects contact, bed course is placed in pipeline and is in contact with it object
Between body, the two is separated using bed course, avoids contact with corrosion.
A kind of specific preservation process of aerial pipeline anti-corrosive apparatus of the utility model is as follows:
(1) line treatment: being derusted and cleaned to pipeline surfaces externally and internally, removal rusty stain and other spot impurity；
(2) anticorrosion with painting loses layer: preparing anticorrosive coating according to the component ratio, anticorrosive coating is sprayed at defeated
Pipe surface is sent, it is repeated multiple times to spray the corrosion-resistant coating for forming high quality；
(3) insulating layer and protective layer are set: being wrapped in pipeline with insulating layer, is then wrapped in insulating layer with protective layer again
Outside, using its elasticity, protective layer is made to be close to insulating layer；
(4) wind radiation protective layer: aluminium foil uvioresistant anti-corrosion Cold winding band viscosity is stronger, is wound on the protection layer,
It is pasted tightly not fall off on the protection layer；
(5) it makes outer corrosion-resistant coating: two component of a, b for forming epoxy resin being mixed according to 3 to 1 ratio, stirring is equal
It is even, and rapid application forms outer corrosion-resistant coating in radiation protective layer surface before it is solidified after solidification；
(6) bed course is set: in the position that pipeline is contacted with other objects, bed course being placed between pipeline and contactant.
The utility model has the beneficial effects that (1) construction technology is simple, material therefor is cheap, at low cost；(2) outer anticorrosion
The setting of layer protects radiation protective layer, avoids radiation protective layer from being corroded by the external world, and outer anticorrosion is transparent, does not influence radiation protective layer work
With；(3) using the anticorrosive coating voluntarily prepared, it is more preferable to be formed by corrosion-resistant coating anti-corrosion effect；(4) presence of bed course avoids
Tube contacts to object it is corroded.
