Abstract
The utility model discloses an anticorrosion pipeline, including pipe body (1), the coating has anticorrosive coating (2) on the internal surface of pipe body (1), anticorrosive coating (2) are waterborne inorganic zinc rich paint layer. The utility model discloses an at the local coating anticorrosive coating that pipe inner wall and pumped (conveying) medium contacted, anticorrosive coating wherein adopts waterborne inorganic zinc rich paint layer, through inside lining one deck waterborne inorganic zinc rich paint layer on pipe inner wall, can prevent that the pipeline from taking place to corrode, has prolonged the life of pipeline.
Description
Technical field
The utility model relates to a kind of anti-corrosion pipeline.
Background technique
Pipeline is when long-term conveying fluid or solid material, and often will stand the corrosion of fed sheet of a media, corrosion not only can reduce the intensity of pipeline, shortens pipeline life, also can increase discharge pressure.Because corrosion causes structural failure and destruction, the property even loss of life are of common occurrence, can say that corrosive pipeline is one of maximum factor affecting its life-span.Corrosion failure or fracture not only cause the leakage of harmful matter, pollute environment, sometimes also can cause the catastrophic failure of burst, jeopardize the safety of the mankind.
Model utility content
For this reason, the utility model is in order to prevent corrosive pipeline, and extend pipeline life, the utility model provides a kind of anti-corrosion pipeline.
Adopt technological scheme as described below:
A kind of anti-corrosion pipeline, comprise tube body, the internal surface of described tube body is coated with anticorrosive coat, described anticorrosive coat is aqueous inorganic zinc rich paint layer.
Described anticorrosive coat thickness is 50-200 μm.
The outer surface of described tube body is all coated with aqueous inorganic zinc rich paint layer.
Anticorrosive coat thickness on the described tube body contacted with corrosive deposit be greater than be positioned at all the other positions of described tube body be coated with the thickness of anticorrosive coat.
The utility model has following beneficial effect relative to prior art:
A. the utility model is coated with anticorrosive coat by the place contacted with fed sheet of a media at inner-walls of duct, anticorrosive coat wherein adopts aqueous inorganic zinc rich paint layer, by liner one deck aqueous inorganic zinc rich paint layer on inner-walls of duct, can prevent pipeline from corroding, extend the working life of pipeline.
B. the utility model also at the outer surface coating aqueous inorganic zinc rich paint layer of whole pipeline, not only can prevent the corrosion of fed sheet of a media, can also play the effect preventing surrounding medium from corroding simultaneously.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is pipeline section structural representation provided by the utility model;
Fig. 2 is the pipeline section structural representation of another mode of execution of the utility model;
In figure: 1-tube body; 2-anticorrosive coat.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
As shown in Figure 1, the utility model provides a kind of anti-corrosion pipeline, comprises tube body 1, the internal surface of tube body 1 is coated with anticorrosive coat 2, and anticorrosive coat 2 is aqueous inorganic zinc rich paint layer.
Wherein anticorrosive coat 2 thickness is 50-200 μm; The utility model preferably adopts 75 μm.
Further preferably; as shown in Figure 2; aqueous inorganic zinc rich paint layer is all coated with at the whole outer surface of tube body 1; the inner-walls of duct of long-term and flowing medium contact segment so not only can be protected from corrosion; it also avoid the corrosion that surrounding medium causes tube body outer wall simultaneously, extend the working life of pipeline further.
In addition, the anticorrosive coat thickness on the tube body contacted with corrosive deposit in the utility model be greater than be positioned at all the other positions of tube body be coated with the thickness of anticorrosive coat.That is, if inner-walls of duct is for carrying corrosive deposit, the anticorrosive coat thickness that its inwall is coated with is greater than the anticorrosive coat thickness that its outer wall is coated with.
Wherein aqueous inorganic zinc rich paint layer can be arbitrary product on sale on the market, and for making the fully disclosed object of specification, aqueous inorganic zinc rich paint layer of the present utility model comprises following component:
Basal liquid: basal liquid is the aqueous solution of lithium metasilicate; The concentration of basal liquid mesosilicic acid lithium is 20wt%.
Filler: filler is nano zinc powder, nano aluminium oxide Al
2o
3with the mixture of filler auxiliary material, filler auxiliary material is silicon carbide SiC, and nano aluminium oxide accounts for 20% of filler gross weight, and filler auxiliary material silicon carbide SiC accounts for 20% of filler gross weight; Nano zinc powder is the high-purity zinc powder that purity is greater than 99%.
Basal liquid and filler weight part are than being 1:1.5.
The preparation method of above-mentioned aqueous inorganic zinc rich paint layer comprises the steps:
S1: the preparation of basal liquid
S11: 107g solid lithium hydroxide LiOH being dissolved in 800ml temperature is in 50 DEG C of hot water, forms LiOH solution;
S12: slowly join in LiOH solution by the 133g silica sand of particle diameter < 20 μm, Keep agitation is until form transparent silicic acid lithium Li respectively
2siO
3solution, basis of formation liquid.
S2: the preparation of filler
Nano zinc powder, nano-oxide are mixed with filler auxiliary material;
Basal liquid and filler pack placement respectively.
During use, hull surface to be sprayed is cleaned up, make its roughness be 40-75 μm.
Added to by filler in described basal liquid, be sprayed on pipeline to be sprayed, film-forming after stirring, coating thickness is 75 μm.
Normal temperature adhesion test result: (cross-hatching) 1 grade, (pulling open method) 10.0MPa, after 280 DEG C of heating 6h, adhesion is still 1 grade, does not occur phenomenons such as bubbling, come off; Pencil hardness 5H, impact resistance 50kg.cm, wear resistance (knockout method) 18.0L/ μm; Resistance to 5wt.% salt spray test >=6000h, the phenomenon such as do not occur bubbling, come off, get rusty; Surface drying time 20min, does solid work time 30min.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
