Abstract
The invention discloses a corrosion-resistant galvanized steel tube which comprises an uppermost layer, a middle layer and a lowermost layer. The uppermost layer is made of sulfate zinc coatings, the middle layer is made of epoxy resin, the lowermost layer is made of silicon iron, the sulfate zinc coatings account for 31%-34% of the weight of a corrosion-resistant galvanized steel tube body, the epoxy resin accounts for 21%-30% of the weight of the corrosion-resistant galvanized steel tube body, and the silicon iron accounts for 44%-45% of the weight of the corrosion-resistant galvanized steel tube body. The corrosion-resistant galvanized steel tube has the advantages of good adhesion, high corrosion resistance, strong-acid resistance and the like.
Description
Technical field
The present invention relates to a kind of steel pipe, relate in particular to a kind of Coating Steel Pipe of corrosion resistance.
Background technique
Steel pipe is not only for delivery of fluid and powdery solid, exchange heat energy, manufacturing machine part and container, it or a kind of economic steel.With steel pipe, manufacture building structure rack, pillar and machinery mount, can weight reduction, save metal 20~40%, and can realize batch production mechanized construction.(job shop of Tianjin Steel Pipe Corp. is owing to having adopted steelpipe net shelf structure; actual saving steel reaches 42.9%); with steel pipe, manufacture highway bridge and not only can save steel, simplify construction, and can greatly reduce the area of stopping off, save investment and maintenance cost.So the steel of any other type all can not replace steel pipe completely, but steel pipe can replace part section bar and bar.Steel pipe is very large to the raising relation of the national economic development and human lives's quality, outclass other steel.From people's daily apparatus, furniture, water supply and sewage, air feed, ventilation and heating facility to the manufacture of various agricultural machinery apparatus, the exploitation of underground resources, national defence and space flight firearms used, bullet, guided missile, rocket etc. all be unable to do without steel pipe.Old house major part be use be all galvanized pipe, the that iron pipe that coal gas, heating installation are used is now also galvanized pipe, galvanized pipe is as water pipe, use after several years, in pipe, produce a large amount of rust deposites, the yellow water of outflow not only pollutes sanitary equipment, and is being mingled with the bacterium that rough inwall grows, corrosion causes in water content of beary metal too high, the health of serious harm human body.
Summary of the invention
The object of the present invention is to provide a kind of Coating Steel Pipe of corrosion resistance, there is adhesion good, corrosion resistance strong and can resistance to strong acid etc. advantage.
Technological scheme of the present invention is: a kind of Coating Steel Pipe of corrosion resistance, the Coating Steel Pipe of described corrosion resistance comprises the superiors, mesosphere and orlop, the described the superiors are sulfate zinc platings, described mesosphere is epoxy resin, described orlop is ferrosilicon, described sulfate zinc plating accounts for the 31%-34% of the Coating Steel Pipe body weight of corrosion resistance, described epoxy resin accounts for the 21%-30% of the Coating Steel Pipe body weight of corrosion resistance, and described ferrosilicon accounts for the 44%-45% of the Coating Steel Pipe body weight of corrosion resistance.
In a preferred embodiment of the present invention, described ferrosilicon comprises coke, steel cuttings, quartz and silica.
In a preferred embodiment of the present invention, described sulfate zinc plating account for corrosion resistance Coating Steel Pipe body weight 32%, described epoxy resin account for corrosion resistance Coating Steel Pipe body weight 23%, described ferrosilicon account for corrosion resistance Coating Steel Pipe body weight 45%.
The Coating Steel Pipe of a kind of corrosion resistance of the present invention, has adhesion good, corrosion resistance strong and can resistance to strong acid etc. advantage.
Accompanying drawing explanation
Coating Steel Pipe one preferred embodiment that accompanying drawing 1 is corrosion resistance of the present invention main TV structure schematic diagram.
In accompanying drawing, the mark of each parts is as follows: 1, the superiors, 2, mesosphere, 3, orlop.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, Fig. 1 is the Coating Steel Pipe of a kind of corrosion resistance of the present invention, and the Coating Steel Pipe of described corrosion resistance comprises the superiors 1, mesosphere 2 and the most lower 3 layers, and the described the superiors 1 are sulfate zinc platings, described mesosphere 2 is epoxy resin, and described orlop 3 is ferrosilicon.
Further illustrate, described ferrosilicon comprises coke, steel cuttings, quartz and silica, described sulfate zinc plating account for corrosion resistance Coating Steel Pipe body weight 32%, described epoxy resin account for corrosion resistance Coating Steel Pipe body weight 23%, described ferrosilicon account for corrosion resistance Coating Steel Pipe body weight 45%.Sulfate zinc plating great advantage be current efficiency up to 100%, deposition rate is fast, this is that other zincincations are unrivaled.Because coating crystallization is careful not, dispersibility and covering power are poor, thereby are only suitable for the plating such as the simple tubing of geometrical shape and wire rod.Sulphate Zinc-Fe Alloy Plating Process is optimized traditional sulfate zinc plating technique, has only retained main salt zine sulfate, and all the other components are all given up.In forming new process formula, add again appropriate molysite, make original monometallic coating form zn-fe alloy coating.The restructuring of technique, has not only developed the advantage that former process current efficiency is high, deposition rate is fast.
Further illustrate, described epoxy resin is made through epoxidization by two keys of alicyclic olefin, and the former is directly connected on alicyclic ring epoxy group, and the latter's epoxy group is to be all connected on benzene nucleus or aliphatic hydrocarbon with glycidyl ethers.The solidfied material of cycloaliphatic epoxy resin has following characteristics: 1. higher compression and tension intensity; 2. cruelly put under high temperature condition for a long time and still can keep good mechanical property; 3. arc resistance, resistance to UV aging energy and weathering resistance are better.
Further illustrating, described ferrosilicon has intensity, the consistency and elasticity that significantly improves steel, improves the permeability of steel, reduces the hysteresis loss of Transformer Steel.Siliceous 0.15%-0.35% in general steel, siliceous 0.40%~1.75% in structural steel, in tool steel siliceous 0.30%~1.80%, in spring steel siliceous 0.40%~2.80%, siliceous 3.40%~4.00% in Stainless Acid Resistant Steel, siliceous 1.00%~3.00% in refractory steel, in silicon steel siliceous 2%~3% or higher.The Coating Steel Pipe of a kind of corrosion resistance of the present invention, has adhesion good, corrosion resistance strong and can resistance to strong acid etc. advantage.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
