Ferries, ships and the like are important transportation means of national economy, and almost every bulk material in national trade basically plays a role in the economic operation of the world by means of marine ships. It can be said that ships are basically an important foundation stone for human development. Safety of driving out in the ocean is also an important concern. Marine difficulties are inevitable in the world, and the proportion of striking reefs in the marine difficulties is large. Such as the broadcast of the majors as movie < Tatannik number >, etc. It also has profound effects in the world.
In economic activities. On the deck of a ship, there are basically main bodies for loading a large number of tools or materials such as vehicles and containers for working equipment. The deck is subjected to various material and equipment friction, seawater dry-out corrosion and the like, which sometimes account for a large proportion of the maintenance of the deck, and the common practice is that: flushing the deck with fresh water to remove salt; shoveling, removing rust packages and rust blocks, and preventing the rust packages and the rust blocks from continuously spreading to protect adjacent parts of the rust packages and the rust blocks; polishing the rust removal part to remove rust; cleaning the rust removing surface and keeping the surface clean before painting; and (5) repairing the paint and brushing the paint again.
The large ships are mostly double-hull ships, so that at least risks can be prevented to a certain extent once the reef is touched, but the conventional maintenance method can only tow ships to return to the port for maintenance once the reef is touched.
On deck, however, the general wear resistance is limited. Most of the practice is to maintain the deck only as described above.

Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
Examples
The main construction parts of the ship are divided into two parts, namely a ship deck and a ship bottom.
The ship deck:
firstly, polishing surface paint. And (3) polishing the surface paint surface by using processes of sand paper, a polishing wheel or sand blasting and the like to a certain rough surface, and cleaning surface dust to prepare for the next step. The rough surface is specially polished to improve the bonding force. 50, 60, 80, 100, 120, 150, 180, 220, 280, 320, 400, 500 and 600 mesh, preferably coarser sand paper, grinding wheel or quartz sand.
Secondly, in order to improve the bonding force with the anti-yellowing isocyanate-containing nano-structured explosion-proof material, a layer of primer, preferably epoxy primer or polyurethane primer, can be brushed, and the anti-yellowing isocyanate-containing nano-structured explosion-proof material can be sprayed after the primer is coated and dried.
And thirdly, taking a component A and a component B of the anti-yellowing explosion-proof material containing the isocyanate nano structure, which are prepared in advance. Was fitted to a curek H-XP3 apparatus, with which A, B two-component spray was applied. Because the anti-yellowing anti-explosion material containing the isocyanate nano structure can be integrally formed, in order to improve the deformation resistance and the protection effect, the nano anti-explosion material needs to be sprayed on the surface of the whole deck, and screws need to be screwed or exposed. And sticking adhesive paper or other materials to block the corresponding position in advance. After the spraying was completed, the excess was cut off with a sharp blade.
Fourthly, materials are saved sometimes, and meanwhile, the purpose of protection is achieved: the thicker nanometer explosion-proof material can be designed and constructed at the position where the friction is more, and the thinner nanometer explosion-proof material can be sprayed on the other surface which is not impacted. But the integral painting is to be understood, in general, we refer to the whole painting of the upper and lower surfaces and the whole edge, but in terms of the deck, the integral painting refers to the whole surface of the deck due to too large area.
Bottom of the ship:
firstly, a large amount of organisms such as seaweeds, scallops, conchs and the like are grown at the bottom of an old ship, the microorganisms are removed in advance, the ship is polished to a primer, and the bottom of the ship is stored to be dry and clean. The polishing should have a certain roughness. Like the deck, the rough surface is intentionally ground for improved cohesion, to 50, 60, 80, 100, 120, 150, 180, 220, 280, 320, 400, 500, 600 mesh, preferably with coarser sandpaper, grinding wheels or quartz sand.
Secondly, in order to improve the bonding force with the anti-yellowing isocyanate-containing nano-structured explosion-proof material, a layer of primer, preferably epoxy primer or polyurethane primer, can be brushed, and the anti-yellowing isocyanate-containing nano-structured explosion-proof material can be sprayed after the primer is coated and dried.
And thirdly, taking a component A and a component B of the anti-yellowing explosion-proof material containing the isocyanate nano structure, which are prepared in advance. Fitted to a curek H-XP3 apparatus, with which A, B two-component spray was applied; the anti-explosion material containing the isocyanate nano structure can be integrally formed due to yellowing resistance. In order to improve the deformation resistance and the protection effect, a nano explosion-proof material needs to be sprayed on the whole deck surface, screws need to be left and screwed or the corresponding positions need to be exposed, gummed paper or other materials are made to block the corresponding positions in advance, and after the spraying is finished, the redundant parts are cut off by a sharp blade.
Fourthly, materials are saved sometimes, and meanwhile, the purpose of protection is achieved: the thicker nanometer explosion-proof material can be designed and constructed at the position where the friction is more, and the thinner nanometer explosion-proof material can be sprayed on the other surface which is not impacted. However, the entire coating is applied, and in general, the entire coating is referred to as the entire upper and lower surfaces and the entire edge, but the entire coating refers to the entire bottom of the ship due to the large area of the ship bottom.
