Thereby the anti-corrosion sleeve has the performances of water resistance, wear resistance, high strength, corrosion resistance, aging resistance, high strength, wear resistance and the like. Thereby reducing the probability of corrosion of the cladding structure. And plasticizing the mixed polyurethane material to generate a plasticized polyurethane material. Therefore, the solid plasticized polyurethane material can be obtained by plasticizing the mixed polyurethane material, so that the anti-corrosion sleeve can be obtained by subsequent processing. And finally, performing calendering treatment on the plasticized polyurethane material and the composite cloth to generate the anti-corrosion sleeve. Therefore, on the basis that polyurethane has high performances such as water resistance, wear resistance, high strength, corrosion resistance, aging resistance and the like, the gridding cloth has high tensile strength, tear strength and impact resistance, so that the obtained anticorrosion sleeve has the water resistance, wear resistance, tear strength and impact resistance.

Factors that further contribute to a high probability of collapse of marine structures tend to be as follows: it is not determined whether there is a major damage to the corrosion protection coating, resulting in a higher probability of corrosion of the marine structure. If the above factors are solved, the effect of further reducing the probability of collapse of the marine structure can be achieved. In order to achieve the effect, two images of the anti-corrosion sleeve under illumination at different positions are collected, and color comparison is carried out according to the two collected images and the anti-corrosion sleeve image without damage, so that pixel blocks with low similarity can be screened out, namely the pixel blocks with damage are represented in the two images.

Therefore, the accuracy of screening out the pixel blocks representing the breakage is further improved. Finally, the size information of the breakage can be determined from the pixel blocks where the breakage exists. Therefore, the anti-corrosion sleeve with small damage can be screened out. This reduces the probability of corrosion of the marine structure, and thus reduces the probability of collapse of the marine structure.

The preset abnormal area condition may be that an area corresponding to the abnormal area is greater than a first preset abnormal area threshold and smaller than a second preset abnormal area threshold.

The above-mentioned related matters serve as an invention point of the present disclosure, thereby solving the technical problems mentioned in the background art, i.e. it is not determined whether the corrosion-resistant coating has a large number of bulges, which further results in a high probability of corrosion of the marine structure, and a high probability of collapse of the marine structure. Further factors that lead to a higher probability of collapse of marine structures tend to be as follows: it was not determined whether a greater number of bulges were present in the corrosion-resistant coating, further resulting in a higher probability of corrosion of the marine structure. If the above factors are solved, the effect of further reducing the probability of the marine structure collapsing can be achieved. To achieve this, first, the region in which an abnormality exists in the plasticized polyurethane material is determined, and thus, the region in which an abnormality exists in the plasticized polyurethane material can be determined. Then, the area of the abnormal region can be determined, and screening can be performed according to the area range of the bulge. Thus, anomalous regions characterized as noise or other non-characterized bumps can be culled from the set of anomalous regions. Therefore, the accuracy of screening the abnormal area representing the bulge is further improved. Thereafter, the length and width of the abnormal region may be further screened. Therefore, the accuracy of screening the abnormal region representing the bulge is further improved. And finally, determining the total area of all areas representing bulges, thus determining whether more bulges exist in the plasticized polyurethane material, removing the plasticized polyurethane material by the more bulges existing in the plasticized polyurethane material, and only retaining the plasticized polyurethane material with less or no bulges so as to ensure higher ductility and higher impact resistance of the subsequently obtained anti-corrosion sleeve, so that the corrosion probability of the marine structure can be reduced, and the collapse probability of the marine structure can be reduced.
The above embodiments of the present disclosure have the following advantages: through the preparation method of the anti-corrosion sleeve of some embodiments of the disclosure, the prepared anti-corrosion sleeve has better waterproof wear resistance, tensile strength, tear strength and impact resistance, and the damage probability is lower, so that the probability that an ocean structure wrapped by the anti-corrosion sleeve is corroded can be reduced, and the collapse probability of the ocean structure is further reduced. In particular, the higher probability of collapse of marine structures is due to: the anticorrosive coating that is in the area that the unrestrained flower splashes for a long time and sea water tidal range district exposes in sea wind, sunshine and wave environment, under the impact of sea wind and unrestrained flower, the coating drops easily, leads to taking place damaged probability higher, moreover because most ocean steel construction is in the position in the area that the unrestrained flower splashes and sea water tidal range district, cause to apply paint repair construction difficulty again and consuming time longer, can not restore sooner when the coating appears damaged, cause the probability that marine structure is corroded to be higher. Based on this, the method for manufacturing the anticorrosion cover of some embodiments of the present disclosure first performs a calendering process on the needle punched cotton and the mesh fabric to generate the composite fabric. Therefore, the grid cloth has higher tensile strength, tear strength and impact resistance, so that the tensile strength, tear strength and impact resistance of the obtained composite cloth can be improved. Next, the polyurethane particles are subjected to a drying treatment to produce dried polyurethane particles. This makes it possible to remove moisture from the polyurethane particles and sufficiently dry the particles. Then, the dry polyurethane particles, the wear-resistant agent and the reinforcing agent are mixed to generate a mixed polyurethane material. Therefore, the polyurethane has the high performance of water resistance, wear resistance, high strength, corrosion resistance, aging resistance and the like, and the strength and the wear resistance of the mixed polyurethane material can be improved by adding the wear-resistant agent and the reinforcing agent. Thereby the anti-corrosion sleeve has the performances of water resistance, wear resistance, high strength, corrosion resistance, aging resistance, high strength, wear resistance and the like. Thereby reducing the probability of corrosion of the clad structure. And then plasticizing the mixed polyurethane material to generate a plasticized polyurethane material. Therefore, the solid plasticized polyurethane material can be obtained by plasticizing the mixed polyurethane material, so that the anti-corrosion sleeve can be obtained by subsequent processing. And finally, performing calendering treatment on the plasticized polyurethane material and the composite cloth to generate the anti-corrosion sleeve. Therefore, on the basis that polyurethane has high performances such as water resistance, wear resistance, high strength, corrosion resistance, aging resistance and the like, the gridding cloth has high tensile strength, tear strength and impact resistance, so that the obtained anticorrosion sleeve has the water resistance, wear resistance, tear strength and impact resistance. The obtained anti-corrosion sleeve has waterproof wear resistance, tensile strength, tear strength and impact resistance, so that the damage probability of the anti-corrosion sleeve can be reduced. Therefore, the preparation method of the anti-corrosion sleeve disclosed by some embodiments of the disclosure enables the prepared anti-corrosion sleeve to have good waterproof wear resistance, tensile strength, tear strength and impact resistance, and the breakage probability is low, so that the probability that the marine structure wrapped by the anti-corrosion sleeve is corroded can be reduced, and the probability that the marine structure collapses is further reduced.
