[0035] In this embodiment, a method for determining the coating thickness of a conductive coating is provided. Figure 2 : is a flow chart of an optional method for determining the coating thickness of a conductive coating according to an embodiment of the present application, the process comprising the following steps S200-S220:

[0036] Step S200 , performing finite element analysis on the object to be coated to determine target coating parameters for multiple regions of the object to be coated.

[0037] Among them, the target coating parameters include target coating thickness range and target potential.

[0038] Among them, underwater steel structures such as offshore platforms, hulls and submarine pipelines are usually exposed to harsh marine environments and are susceptible to electrochemical corrosion. Therefore, impressed current cathodic protection (ICCP) strategy is used for corrosion protection. The ICCP strategy improves the surface conductivity of the material by coating a layer of conductive material on the surface of the steel structure, optimizing the current distribution and potential control to improve the anti-corrosion performance of the structure. However, after coating the conductive material, the current distribution may be uneven, resulting in local over-protection or under-protection, affecting the structural life and anti-corrosion efficiency.

[0039] Among them, finite element analysis (FEA) is a numerical calculation method that divides a complex entity or system into many small, simple, regular-shaped parts (called finite elements), applies physical laws to these small elements, and then solves them by numerical methods to predict the behavior of the entity or system. The thickness design of the conductive coating of the object to be coated is optimized by finite element analysis to ensure that the specific area of ​​the underwater steel structure (object to be coated) achieves uniform current distribution and potential control. By simulating the conductivity and electric field distribution of the coating, the influence of different coating thicknesses on the current distribution can be predicted, thereby providing a basis for the selection of coating thickness, and the target coating thickness range and target potential of each area of ​​the object to be coated can be determined to make the current distribution of the object to be coated uniform and improve the anti-corrosion effect.

[0040] Step S210 , establishing a coating thickness determination model according to the cost parameter, the coating areas of the plurality of regions of the object to be coated and the target coating parameter.

[0041] The cost parameters may include the cost of the conductive material and the cost of construction (spraying, curing and other operations).

[0042] Step S220 , under the set constraints and optimization objectives, according to the coating thickness determination model, determines the coating thickness of multiple areas of the object to be coated.

[0043] The optimization goal is to minimize the cost of the conductive coating and to achieve the corresponding target potential in each area of ​​the object to be coated. First, the target potential of each area of ​​the object to be coated is determined by finite element analysis, and then the target potential is used as the optimization goal. The coating thickness is adjusted so that the potential of each area of ​​the object to be coated is close to the corresponding target potential, so that the current distribution of the object to be coated is more uniform.

[0044] In this embodiment, the object to be coated is first subjected to finite element analysis to determine the target coating parameters of multiple regions of the object to be coated, thereby determining the coating parameters of the key parts of the object to be coated, so as to provide reference data for the subsequent coating thickness determination. Then, according to the cost parameters, the coating areas of multiple regions of the object to be coated and the target coating parameters, a coating thickness determination model is established to balance the coating cost and the coating protection effect. Finally, under the set constraints and optimization goals, the coating thickness of multiple regions of the object to be coated is determined according to the coating thickness determination model, and the optimization goal is to minimize the cost of the conductive coating and the potential of each region of the object to be coated reaches the corresponding target potential, so that the protection effect can be taken into account while ensuring the lowest cost, that is, the potential of each region reaches the corresponding target potential to achieve the effect of uniform current distribution, which can improve the protection effect and the service life of the steel structure.

[0045] In one embodiment, Figure 3 As shown, step S210, according to the cost parameter, the coating area of ​​multiple regions of the object to be coated and the target coating parameter, a coating thickness determination model is established. It includes: steps S300-S330. Among them:

[0046] Step S300, obtaining the area of ​​the target region of the object to be coated, the construction cost, and the unit volume cost of the material of the conductive coating.

[0047] The target area is one of the multiple areas.

[0048] Step S310 , establishing a cost function for the target area according to the area of ​​the target area of ​​the object to be coated, the construction cost, the unit volume cost of the conductive coating material, and the target coating thickness range of the target area.

[0049] Among them, the cost function of the target area can be expressed as follows:

[0050] C i =(A i ·t i ·c m +P i )

[0051] Among them, C i is the cost of the target area, A i is the area of ​​the target area, t i is the coating thickness in the target area, c m is the unit volume cost of the material, P i is the construction cost of the target area.

[0052] Step S320 , determining a total cost function of the object to be coated according to the cost functions of each region of the object to be coated.

[0053] After determining the cost function of each area of ​​the object to be coated, the cost functions of all areas are added together to obtain the total cost function of the object to be coated, as shown below:

[0054]

[0055] Among them, C 涂层 is the total cost of the object to be coated, A i is the area of ​​the ith region, t i is the coating thickness of the ith region, c m is the unit volume cost of the material, P i is the construction cost of the ith area.

[0056] Step S330 , establishing a coating thickness determination model according to the total cost function of the object to be coated and the target potential and actual potential of each area.

[0057] Among them, the coating thickness determination model needs to take into account the total cost and protection effect of the object to be coated. Therefore, it can be expressed by the following formula:

[0058]

[0059] Among them, C 涂层 is the total cost of the object to be coated, α is the adjustment coefficient, V obj is the target potential of the jth region, V j is the actual potential of the jth region, and m is the total number of regions.

[0060] The optimization goal is to minimize the cost of the conductive coating and to ensure that the potential of each area of ​​the object to be coated reaches the corresponding target potential. Therefore, the value of the coating thickness determination model needs to be minimized. obj -V j | represents the deviation between the actual potential and the target potential of the jth region, |V obj -V j The smaller | is, the closer the actual potential of the jth region is to the target potential, that is, the better the protection effect is. 涂层 The smaller the total cost, the lower the The optimization goal can be met if the minimum value is obtained, that is, the coating thickness of each area that minimizes the value of the coating thickness determination model is determined.

[0061] In this embodiment, a cost function of the target area is first established to quantify the cost of the target area and accurately determine the cost of the target area, thereby determining the total cost of the object to be coated. Then, based on the total cost function and the potential of the object to be coated, a coating thickness determination model is established. The optimization goal of the coating thickness determination model is to minimize the cost of the conductive coating and ensure that the potential of each area of ​​the object to be coated reaches the corresponding target potential, thereby facilitating the optimal design and thickness selection of the conductive coating, taking into account both cost and protection effect.

[0062] In one embodiment, the constraint conditions include: the coating thickness of the target area is within a corresponding target coating thickness range, and the current density of the target area is within a preset current density range.

[0063] Specifically, the target coating thickness range t for each area was first determined by finite element analysis. min ~t max Therefore, the first constraint is that the coating thickness is within the corresponding target coating thickness range: t min ≤t i ≤t max , where t min and t max are the lower and upper limits of the target coating thickness range of the ith region, respectively, and t i is the thickness of the ith region.

[0064] The second constraint is the current distribution uniformity limit: Among them J j is the current density in the jth region, J obj is the target current density of the jth region, and ε is the allowable deviation. The relationship between current density and potential is:

[0065] J j =σ j ·E j

[0066] Among them, σ j is the conductivity of the jth region (S / m), which is related to the properties of the conductive coating material and its thickness. is the electric field strength in the jth region (V / m), given by the potential gradient Sure.

[0067] In this embodiment, the constraint conditions in the coating thickness adjustment process are designed to constrain the coating thickness range on the one hand and the current density range of the region on the other hand, thereby ensuring that the coating thickness and current density are appropriate.

[0068] In one embodiment, Figure 4As shown, step S200 is to perform finite element analysis on the object to be coated to determine target coating parameters for multiple regions of the object to be coated. It includes: steps S400-S430. Among them:

[0069] Step S400: establishing a finite element model of the object to be coated.

[0070] Step S410: dividing the finite element model into multiple regions.

[0071] Step S420, determining the corrosion risk level of each area according to the shape, position, and current distribution of each area.

[0072] Among them, the finite element model is used to simulate the power supply, and the potential of multiple monitoring points of the finite element model is monitored. The current distribution can be obtained according to the simulation results, and then the corrosion risk level of different areas can be determined according to the shape and position of the steel structure.

[0073] Step S430, determining a target coating parameter for each region based on the corrosion risk level of each region.

[0074] Among them, the coating can be selectively thickened at key locations (such as edges, raised parts, welding points), for example:

[0075] Areas with high corrosion risk (such as sharp edges of structures, welds): coating thickness is 200-300μm.

[0076] Medium corrosion risk areas (such as joints): coating thickness is 100-150μm.

[0077] Low corrosion risk areas (such as flat large surface): coating thickness is 50-100μm.

[0078] In this embodiment, finite element analysis and multi-point potential monitoring can be performed on the object to be coated to determine the corrosion risks of different areas, and then target coating parameters for different areas can be designed, so as to increase the coating thickness in areas that are prone to corrosion to improve the protective effect, and reduce the coating thickness in areas that are not prone to corrosion to save costs.

[0079] In one embodiment, the material of the conductive coating includes at least one of epoxy resin doped with highly conductive carbon nanotubes, graphene, and silver powder.

[0080] In this embodiment, the material of the conductive coating is selected to include at least one of epoxy resin doped with highly conductive carbon nanotubes, graphene and silver powder, thereby ensuring that the material of the conductive coating has excellent conductivity, adhesion and corrosion resistance, thereby improving the protection effect.

[0081] In one embodiment, Figure 5As shown, a method for coating a conductive coating is provided, and the coating thickness of multiple areas of the object to be coated is determined by using the method for determining the coating thickness of the conductive coating in any of the above embodiments. The method for coating a conductive coating includes: steps S500-S510. Among them:

[0082] Step S500 , in a dry environment, spraying a conductive coating on the object to be coated according to the determined coating thicknesses of multiple regions of the object to be coated.

[0083] Step S510, placing the object to be coated after spraying the conductive coating at a preset temperature for a preset time to allow the conductive coating to cure at a constant temperature.

[0084] Exemplarily, the preset temperature may be 60° C. to 80° C., and the preset time may be 24 hours.

[0085] In this embodiment, the coating is carried out in a dry environment using an automated spraying device to ensure uniformity and controllable thickness of the coating. After coating, the coating is fully cured by constant temperature curing to form a stable anti-corrosion protective layer.

[0086] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
