Description
Technical field
The present invention relates to aqueduct technical fields, and in particular to contains the pre- of the inorganic resistance rust coating of layered double-hydroxide
Heat insulation water transfer pipe road processed.
Background technique
Prefabricated heat-insulation and heat-preservation aqueduct is commonly called as black yellow jacket insulating tube, mainly by instrumentation tubes, insulating layer, outer protection tube three
Part forms, and three component parts have corresponding effect.It is instrumentation tubes pumped (conveying) medium, high pressure resistant；Insulating layer prevents heat waste loss of production
It is raw；Outer protection tube primarily serves the effect of sealing.Outer protection tube is that the water and air in environment is prevented to enter inside pipe insulating layer
Main barrier.However, the prolonged application with Long-distance Pipeline for Water Conveyance under various factors coupling environment, inevitably outer to protect
Pipe may generate aging breakage in certain sections, this will lead to the infiltration of water and air, when water and air reaches outside working steel tube
Surface, steel pipe will gradually corrode.Therefore, the long-term anticorrosion performance of heat-insulation and heat-preservation aqueduct prefabricated over long distances is urgently into one
Step is promoted.
Summary of the invention
The purpose of the present invention is to solve existing prefabricated heat-insulation and heat-preservation aqueduct nothings during long distance water transfer
Method guarantees the problem of long-term anticorrosion performance, and then provides a kind of inorganic resistance rust coating of novel lamellar double-hydroxide, is coated
To the working steel tube outer wall of prefabricated heat-insulation and heat-preservation aqueduct, develop a kind of containing the inorganic resistance rust coating of layered double-hydroxide
Prefabricated heat insulation water transfer pipe road further promotes the long-term anticorrosion performance of prefabricated heat-insulation and heat-preservation aqueduct.
The present invention to achieve the above object, is achieved by the following technical programs: inorganic containing layered double-hydroxide
The prefabricated heat insulation water transfer pipe road of resistance rust coating, the aqueduct includes pipeline body, is coated from level to level outside the pipeline body
The inorganic resistance rust coating of shape double-hydroxide, the layered inorganic resistance rust coating of double-hydroxide are wrapped up outside described in polyurethane insulation coating
External protection is wrapped up outside polyurethane insulation coating.
The material of the pipeline body can be with as a further optimization of the solution, are as follows: seamed steel pipe, seamless steel pipe or double
Face submerged arc spiral welded steel pipe is one such.
The inorganic resistance rust coating of layered double-hydroxide is by the double hydroxides of stratiform as a further optimization of the solution,
The mixed liquor of object and dehydrated alcohol or isopropanol is coated to pipeline body outer surface to be formed.
Specific coating method is, first that layered double-hydroxide and a certain amount of solvent absolute ethyl alcohol or isopropanol is uniform
Mixing, is then uniformly coated to working steel tube outer surface for mixed liquor by way of brushing or spraying.Dehydrated alcohol is different
Propyl alcohol vapors away quickly, and remaining is then the inorganic resistance rust coating of uniform layered double-hydroxide.The double hydroxides of the stratiform
Object (LDH) chemical composition specifically includes that Mg3Al-NO3LDH, Zn2Al-NO3LDH,Ca2Al-Cl LDH,LiAl2-NO3LDH,
Zn2Cr-NO3LDH, Ni2Al-NO3With CaAl-Cl LDH etc..Layered double-hydroxide it is inorganic resistance rust coating thickness range be
1mm-3mm。
The protective layer material is high density polyethylene (HDPE) or glass reinforced plastic as a further optimization of the solution,.
The utility model has the advantages that
The present invention provide it is a kind of containing layered double-hydroxide it is inorganic resistance rust coating prefabricated heat insulation water transfer pipe road, have with
It is lower the utility model has the advantages that
1, existing rise thermal insulation delivery pipe road also has in view of the coating resistance rusty scale outside working steel tube, but general resistance rust method is not
It is only simply to utilize organic polymer class material (such as resin) coating steel pipes of waterproof isolation air from resistance rust mechanism on
Outer surface.Organic polymer class material is using easy aging, and aging is even more serious under high temperature action.From outer protection tube
Infiltration enters the machine high score subclass material coating of working steel tube outer wall, and long term will be difficult to avoid that corrosion.And it is of the invention
The inorganic resistance rust coating of layered double-hydroxide used but can be ageing-resistant, and high temperature resistant, long-term behaviour is stablized.
2, inertia is kept when the inorganic resistance rust coating of layered double-hydroxide is not contacted with water and air, is connect when with water and air
Touching will excite it efficiently to hinder rust ability, and after water and air subsides, the inorganic resistance rust coating of layered double-hydroxide restores lazy again
Property.
3, the configuration of the present invention is simple, and the inorganic resistance rust coating dosage of layered double-hydroxide is few, can be recycled, reliability
It is high.
Detailed description of the invention
The present invention that the following is further explained with reference to the attached drawings:
Fig. 1 is cross section structure schematic diagram of the present invention:
In figure: 1, pipeline body, 2, the inorganic resistance rust coating of layered double-hydroxide, 3, polyurethane insulation coating, 4, protective layer.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract), unless specifically stated,
