[0002] Since most military weapons are made of steel products, they are prone to rust. When it snows, the temperature drops sharply, which not only increases the brittleness of steel products and changes the crystal structure inside the metal, making it prone to rust. When the weapons are exposed to humid air, they will re-condense inside the weapons when shot, further exacerbating the severity of rust. In addition, the corrosiveness of the combustion gases will cause the surface of the components to be rough, and once frozen, they will adhere strongly and are not easy to fall off, which can easily cause accidents.

[0003] However, at present, the maintenance of military weapons is still done by manual wiping and applying gun oil, but especially after rain, the trigger part will rust, causing the gun to fail completely; even if gun oil is used normally, rust is still unavoidable; in low temperature areas or even extremely cold areas, the viscosity of gun oil increases, and even solidifies, causing a large number of weapons to be scrapped, seriously affecting the development of my country's military power. It also causes a huge waste of manpower for soldiers, and even worse, if the weapons are not properly maintained, it will cause harm to relevant personnel when using guns and other weapons.

[0034] In order to further understand the present application, the present application is further described in detail below in conjunction with the best embodiment.

[0035] Example 1

[0039] The opening is an openable opening; that is, when the chemical is not required to enter the mixing and stirring device, the chemical placement space is a closed space; when the chemical is required to enter the mixing and stirring device, the opening can be used to allow the chemical to enter the mixing and stirring device.

[0040] The three chemical placement spaces are respectively a placement space I containing an organosilicon precursor monomer, a placement space II containing a network or gel structure precursor containing a hydrophilic group, and a placement space III for an aliphatic compound precursor.

[0043] The placement space III includes at least four independent placement bins.

[0044] A storage bin contains a precursor of an aliphatic compound; the precursor of the aliphatic compound is an alkyl, alkenyl, alkynyl group containing a substituent and / or a polymer formed by an alkenyl, alkynyl group containing a substituent; when the precursor of the aliphatic compound is an alkyl, alkenyl, alkynyl group containing or not containing a substituent, it is preferably a halogen-substituted alkyl, alkenyl, alkynyl group, which can be a C5-C20 halogenated alkyl, alkenyl, alkynyl group; for example, perfluorobutylethylene and cyclopentene. When the aliphatic compound is a polymer, the precursor of the aliphatic compound is a polyolefin or polyalkyne containing a substituent, which can be polyvinyl chloride, polypropylene chloride, polydichloroprene, polychloroprene, polychloropentene, etc.

[0046] A dispersant is placed in a storage bin; the dispersant includes one of gelatin, polyvinyl alcohol, carboxymethyl cellulose or hydroxypropyl cellulose.

[0047] One of the storage bins contains an initiator; the initiator includes one or more mixtures of diisopropyl peroxydicarbonate, azobisisoheptanenitrile, dodecyl peroxide, acetyl peroxycyclohexanesulfonic acid or dicyclohexyl peroxydicarbonate.

[0048] The storage space is a vacuum-sealed space; that is, each storage bin for chemicals is in an independent vacuum state, which is convenient for the storage of chemicals. Each storage bin is also an independent space state and is not shared with other storage bins.

[0049] The mixing and stirring device is provided with a stirrer; the stirrer is located at the bottom of the mixing and stirring device. The mixing and stirring device also has a feed port; water or an organic solvent etc. can be injected through the feed port, and the injected liquid can be selected according to the properties of each chemical.

[0050] A channel is arranged on the side wall of the mixing and stirring device; the channel is connected with the pipeline of the coating device.

[0051] The coating device comprises: a pipeline connected with the channel, a valve and a spraying panel.

[0052] The solution in the mixing and stirring device can enter the coating device through a pipeline; the amount of the solution and the control time are controlled by a valve.

[0057] The chemical storage space needs to be cooled because some chemicals need to be effectively maintained at low temperatures to avoid deterioration and short life due to high temperatures. The cooling device is located inside the chemical storage space / outside the storage bin, that is, it is not in direct contact with the chemicals and is also outside the container containing the chemicals; the cooling device is a device containing liquid nitrogen. When liquid nitrogen vaporizes, it can take away a lot of heat, thereby maintaining a low temperature environment in the chemical storage space.

[0058] The vents are located around the metal product storage device to enable timely exhaust.

[0059] Preferably, the metal product placement device is located above the chemical storage area and has an air inlet connected to the chemical storage area.

[0060] A heating device is also arranged around the metal product placement device; preferably, the heating device is a heating pipe; the heating pipe is a hollow structure, and contains a flowing medium inside; preferably, hot water; more preferably, water circulated in a cold water circulation device or water circulated in a cold water circulation device and then heated.

[0061] Example 2

[0062] This embodiment provides a method for using a lightweight multifunctional maintenance system. The lightweight multifunctional maintenance system is the same as the lightweight multifunctional maintenance system described in Example 1, and will not be described in detail here.

[0063] The lightweight multifunctional maintenance system as described above includes: (1) opening a chemical placement space to allow the chemicals to enter a mixing and stirring device for mixing and stirring; and (2) allowing the mixed and stirred solution to enter a coating device for coating the metal product.

[0064] Place chemicals in the chemical placement space, and place different chemicals in different placement spaces; place substances that can interact with each other in the same placement space.

[0065] For example, the precursor monomer of silicone is placed separately in the placement space I; the precursor of the network or gel structure containing a hydrophilic group and the initiator capable of initiating the reaction of the substance are placed in different placement bins in the placement space II; the precursor of the aliphatic compound, the catalyst for catalyzing the precursor, the dispersant for dispersion and the initiator for initiating the reaction are placed in different placement bins in the placement space III.

[0066] After that, the air is extracted to make each storage bin vacuum-sealed. Then, a cooling device is placed to keep the chemical storage space at a certain low temperature.

[0067] The chemical storage space can be used to store chemicals when the system is not in use.

[0068] When the system needs to be used, it is only necessary to open the opening at the bottom of the chemical placement space to allow the chemicals to enter the mixing and stirring device, and the chemicals in the storage state can be used.

[0069] Water or organic solution is injected through the feed port of the mixing and stirring device to dissolve the chemicals into a solution, which is convenient for subsequent spraying.

[0070] At the same time, start the agitator of the mixing and stirring device to fully mix the chemicals.

[0071] The order, time and amount of chemicals entering the mixing and stirring device can be controlled by opening or closing the bottom opening of the chemical storage bin.

[0072] For example, if the placement space I contains only one chemical, namely, the organosilicon precursor monomer, then the bottom opening can be opened directly. In the placement space II, there are two chemicals, namely, a precursor with a network or gel structure containing a hydrophilic group and an initiator that can trigger the reaction of the substance; the precursor with a network or gel structure containing a hydrophilic group needs to be mixed with a solvent before adding the initiator to avoid the initiator triggering the reaction too early. In the placement space III, the precursor of the aliphatic compound is evenly mixed with the dispersant and solvent before adding the catalyst or initiator.

[0073] When the mixing and stirring device is turned on, the cooling device should be turned on to control the temperature of the entire mixing and stirring process and slow down the occurrence of the cross-linking reaction at this stage.

[0074] The mixed solution is then transported to the spray panel through a pipe to spray the metal product.

[0075] When three layers of different chemicals are to be sprayed on metal products, it is necessary to control the chemical placement space and the opening at the bottom of the placement bin in each placement space at the same time to achieve the entire three-layer structure. First, open the bottom opening of the placement bin for the precursor monomer of the organic silicon in the placement space I, and at the same time open the cooling device, agitator and feed port of the corresponding mixing and stirring device, and the solvent of the feed port is water. The molar ratio of the solvent I to the precursor monomer of the organic silicon is controlled to be not less than 3:1, preferably (3-10):1, which can be 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1 or 10:1. At this ratio, the precursor monomer of the organic silicon undergoes hydrolysis reaction to the greatest extent without dehydration or dehydrochlorination reaction, that is, in this step, the amount of polysiloxane generated is small; its purpose is to carry out in-situ polymerization later, so the polymerization reaction in the early stage should be minimized. At the same time, the cooling device is turned on to further reduce the progress of the reaction. After that, the mixed and stirred solution enters the coating device through a pipeline to spray the metal surface. It is then air-dried so that the layer is slightly fixed.

[0076] When solution I is applied to the metal surface, it is partially dried so that the layer generates a low polymer of polysiloxane that can partially adhere to the metal surface; then solution II is applied on the first layer and also partially dried so that the organic complex layer and the hydrophilic layer are partially cross-linked.

[0077] While the first layer is air-dried, the bottom opening of the storage bin containing the hydrophilic group-containing mesh or gel structure precursor in the storage space II is opened, and the corresponding cooling device, stirrer and feed port of the mixing and stirring device are connected, and the solvent of the feed port is water. Then, the bottom opening of the storage bin for the initiator is opened, and then the solution is quickly introduced into the coating device through the pipeline to spray the metal surface. Then, air-drying is performed to slightly fix the layer.

[0078] While the second layer is air-dried, the bottom opening of the storage bin for the aliphatic compound precursor and the dispersant in the storage space III is opened, and the cooling device, the stirrer and the feed port of the corresponding mixing and stirring device are connected, and the solvent of the feed port is water or an organic solvent. Then, the bottom opening of the storage bin for the catalyst and / or initiator is opened, and then the solution is quickly introduced into the coating device through the pipeline to spray the metal surface.

[0079] Due to the vaporization of liquid nitrogen, the space where the metal product storage device is located is filled with nitrogen atmosphere, so it only needs to be heated and solidified.

[0080] Turn on the heating device around the metal product storage device; control the temperature to 50-80°C and the time to 20-60 minutes.

[0081] During the heating process, the exothermic polymerization reaction of the hydrophilic layer will further dehydrate or dehydrochlorinate the organic complex layer, resulting in the generation of a large amount of polysiloxane and increasing the molecular weight of polysiloxane; at the same time, polysiloxane cross-links with the hydroxyl, carboxyl or amide groups of the hydrophilic layer to enhance the connection between the two layers. The moisture released by the organic complex layer causes the hydrophilic layer to contain some moisture, causing its degree of polymerization to slightly decrease, forming a gel or mesh structure with a certain elasticity. Due to the heat release of the hydrophilic layer, the temperature of the hydrophobic layer also rises greatly, thereby undergoing condensation or cross-linking reactions with the hydrophilic layer, and finally forming a multifunctional surface care material with a three-layer structure.

[0082] Through the complexation of the organic complex layer with the metal product, it can be closely bonded to the surface of the metal product and repair the defects on the metal surface; the hydrophilic layer can store a certain amount of moisture and reduce the impact of moisture on the metal, while the hydrophobic layer can prevent the intrusion of water vapor.

[0083] Example 3

[0084] The lightweight multifunctional maintenance system and maintenance method in the above-mentioned embodiment may also be modified to make them more suitable for portable and quick maintenance.

[0085] When only small arms or parts are to be maintained, the above maintenance system will cause certain waste, so the above maintenance system is modified to be a portable and small maintenance method.

[0086] The chemical storage area and the mixing and stirring device are the same as those described above; except that an opening is provided in the mixing and stirring device; the opening is connected to the non-woven fabric device through a pipeline; and is used to soak the non-woven fabric with the chemical.

[0087] The non-woven fabric device includes a mechanical arm and a non-woven fabric storage space; in the non-woven fabric storage space, there is a non-woven fabric rack. The non-woven fabric is placed on the non-woven fabric rack, and the opening of the mixing and stirring device is opened to allow the mixed chemical solution to soak the non-woven fabric. After a portion of the non-woven fabric is soaked, the mechanical arm is used to remove the soaked non-woven fabric, and a new non-woven fabric is placed on the rack again.

[0088] The soaked nonwoven fabric is then vacuum packed to obtain a portable maintenance fabric.

[0089] The production and storage process of the portable maintenance cloth are both in a low temperature state; for example, it can be refrigerated by liquid nitrogen, liquid CO2 or ice cubes.

[0090] When the weapon part needs to be maintained, the portable maintenance cloth prepared as above can be used for maintenance.

[0091] After mixing the chemicals in different chemical placement spaces respectively, the openings of the mixing and stirring devices are opened respectively, so that the mixed chemical solution can infiltrate the non-woven fabric; vacuum packaging is performed, and three different portable maintenance cloths are obtained respectively.

[0092] After opening the package of the portable maintenance cloth containing solution I, wipe and squeeze the metal surface so that solution I falls onto the metal surface; then air-dry for 5 minutes.

[0093] After that, open the package of the portable maintenance cloth containing Solution II, wipe and squeeze it so that the substance containing Solution II falls onto the metal surface; then air-dry it for 5 minutes.

[0094] After that, the portable maintenance cloth containing solution III is unpacked, and then wiped and squeezed to make the substance containing solution III fall onto the metal surface.

[0095] Then the temperature is raised and controlled to be 50-80°C for 20-60 minutes; thus, the metal surface can be maintained and a three-layer structure can be achieved on the surface.

[0096] The details are as follows:

[0097] Chemical storage space: There is one storage bin in storage space I, which is a plastic barrel; there are two storage bins in storage space II, both of which are plastic barrels; there are four storage bins in storage space III, one of which is a steel cylinder and three are plastic barrels.

[0098] Place dimethyldichlorosilane in storage space I; place acrylamide and ammonium persulfate in two storage bins in storage space II; place vinyl chloride in the steel cylinder storage bin in storage space III, and place polyvinyl alcohol, diisopropyl peroxydicarbonate and potassium hydroxide in the plastic barrel storage bin in storage space III. Then extract the air so that each storage bin is in a vacuum-sealed state. The above chemicals are kept at a low temperature by slowly releasing liquid nitrogen in the cooling device. The metal product storage device is located above the chemical storage area, and there is an air inlet connected to the chemical storage area; at the same time, the air inlet is opened so that the metal product storage device is in a nitrogen atmosphere.

[0099] Turn on the cooling device of the mixing and stirring device, which is a cold water pipe surrounding the periphery of the mixing and stirring device, to perform cold water cooling in advance.

[0100] First, open the bottom opening of the dimethyldichlorosilane placement bin in the placement space I, which is directly connected to the mixing and stirring device, that is, when the opening is opened, dimethyldichlorosilane falls into the mixing and stirring device; after the number of dimethyldichlorosilane reaches 150 parts, close the opening; open the feed port of the mixing and stirring device, and inject 450 parts of water; turn on the agitator for stirring to obtain solution I.

[0101] The mixed and stirred solution I enters the non-woven fabric storage space through the opening of the side wall of the mixing and stirring device, and soaks the non-woven fabric on the non-woven fabric rack; after soaking, the soaked non-woven fabric is removed by a robotic arm, and then vacuum-packed to obtain a portable maintenance cloth containing solution I.

[0102] Open the bottom opening of the acrylamide placement bin in the placement space II, which is directly connected to the mixing and stirring device. After the acrylamide is 20 parts, close the opening; open the feed port of the mixing and stirring device, and inject 180 parts of water; turn on the agitator to stir and mix evenly; then open the bottom opening of the ammonium persulfate placement bin in the placement space II, which is 1 part, mix and stir to obtain solution II.

[0103] Then, solution II is quickly introduced into the non-woven fabric storage space through the opening of the side wall of the mixing and stirring device to soak the non-woven fabric on the non-woven fabric rack; after soaking, the soaked non-woven fabric is removed by a robotic arm and then vacuum-packed to obtain a portable maintenance cloth containing solution II.

[0104] At the same time, open the bottom openings of the vinyl chloride placement bin and the polyvinyl alcohol placement bin in the placement space III, add 100 parts of vinyl chloride and 0.8 parts of polyvinyl alcohol, and then close the openings; open the feed port of the mixing and stirring device, and inject 120 parts of water; turn on the agitator to stir and mix evenly; then open the openings at the bottom of the diisopropyl peroxydicarbonate placement bin and the potassium hydroxide placement bin in the placement space II, add 0.1 parts of diisopropyl peroxydicarbonate and 0.1 parts of potassium hydroxide, mix and stir to obtain solution III.

[0105] Then, the solution III is quickly introduced into the non-woven fabric storage space through the opening of the side wall of the mixing and stirring device to soak the non-woven fabric on the non-woven fabric rack; after soaking, the soaked non-woven fabric is removed by a robotic arm and then vacuum-packed to obtain a portable maintenance cloth containing the solution III.

[0106] After opening the package of the portable maintenance cloth containing solution I, wipe and squeeze the metal surface so that solution I falls onto the metal surface; then air-dry for 5 minutes.

[0107] After that, open the package of the portable maintenance cloth containing Solution II, wipe and squeeze it so that the substance containing Solution II falls onto the metal surface; then air-dry it for 5 minutes.

[0108] After that, the portable maintenance cloth containing solution III is unpacked, and then wiped and squeezed to make the substance containing solution III fall onto the metal surface.

[0109] The temperature around the metal is controlled at 60°C and the heating time is 60 minutes; then, until the temperature of the metal surface drops to room temperature, a maintenance structure with a three-layer structure (organic complex layer, hydrophilic layer and hydrophobic layer) can be obtained on the surface of the metal product, thereby achieving maintenance of the metal product.

[0110] Example 4

[0111] According to the content of this application, the lightweight multifunctional maintenance system of Example 1 and the method of using Example 2 are specifically described, and the specific description is as follows:

[0112] Test Example 1

[0113] Chemical storage space: There is one storage bin in storage space I, which is a plastic barrel; there are two storage bins in storage space II, both of which are plastic barrels; there are four storage bins in storage space III, one of which is a steel cylinder and three are plastic barrels.

[0114] Place dimethyldichlorosilane in storage space I; place acrylamide and ammonium persulfate in two storage bins in storage space II; place vinyl chloride in the steel cylinder storage bin in storage space III, and place polyvinyl alcohol, diisopropyl peroxydicarbonate and potassium hydroxide in the plastic barrel storage bin in storage space III. Then extract the air so that each storage bin is in a vacuum-sealed state. The above chemicals are kept at a low temperature by slowly releasing liquid nitrogen in the cooling device. The metal product storage device is located above the chemical storage area, and there is an air inlet connected to the chemical storage area; at the same time, the air inlet is opened so that the metal product storage device is in a nitrogen atmosphere.

[0115] Turn on the cooling device of the mixing and stirring device, which is a cold water pipe surrounding the periphery of the mixing and stirring device, to perform cold water cooling in advance.

[0116] First, open the bottom opening of the dimethyldichlorosilane placement bin in the placement space I, which is directly connected to the mixing and stirring device, that is, when the opening is opened, dimethyldichlorosilane falls into the mixing and stirring device; after the number of dimethyldichlorosilane reaches 150 parts, close the opening; open the feed port of the mixing and stirring device, and inject 450 parts of water; turn on the agitator for stirring to obtain solution I.

[0117] The mixed and stirred solution I enters the coating device through the channel on the side wall of the mixing and stirring device, and the valve is controlled to make the solution I pass evenly and finally reach the spraying panel to achieve the first layer of spraying. After the first layer is sprayed, it is air-dried.

[0118] While the first layer is air-dried, the bottom opening of the acrylamide placement bin in the placement space II is opened, and the opening is directly connected to the mixing and stirring device. After the acrylamide is 20 parts, the opening is closed; the feed port of the mixing and stirring device is opened, and 180 parts of water are injected; the agitator is turned on for stirring and mixing evenly; then the bottom opening of the ammonium persulfate placement bin in the placement space II is opened to 1 part, and mixing and stirring are performed to obtain solution II.

[0119] Then, solution II is quickly introduced into the coating device through the channel on the side wall of the mixing and stirring device, and the valve is controlled to make solution II pass evenly and finally reach the spraying panel to achieve the second layer of spraying. After the second layer is sprayed, it is air-dried.

[0120] While the second layer is air-dried, the bottom openings of the vinyl chloride placement bin and the polyvinyl alcohol placement bin in the placement space III are opened simultaneously, and 100 parts of vinyl chloride and 0.8 parts of polyvinyl alcohol are added, and then the openings are closed; the feed port of the mixing and stirring device is opened, and 120 parts of water are injected; the agitator is turned on for stirring and mixing evenly; then the openings at the bottom of the diisopropyl peroxydicarbonate placement bin and the potassium hydroxide placement bin in the placement space II are opened, and 0.1 parts of diisopropyl peroxydicarbonate and 0.1 parts of potassium hydroxide are added, and mixed and stirred to obtain solution III.

[0121] Then, solution III is quickly passed into the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, solution III passes evenly and finally reaches the spraying panel to achieve the third layer of spraying.

[0122] Then, the heating device around the metal product placement device is used; the heating device is a hot water pipe surrounding the outer periphery of the mixing and stirring device, and the hot water is obtained by heating the water in the cold water pipe. The temperature around the metal product placement device is controlled to be 60°C, and the heating time is 60 minutes; then, until the temperature of the metal surface drops to room temperature, a maintenance structure with a three-layer structure (organic complex layer, hydrophilic layer and hydrophobic layer) on the metal product surface can be obtained, thereby achieving maintenance of the metal product.

[0123] Test Example 2

[0124] Chemical storage space: There is one storage bin in storage space I, which is a plastic barrel; there are two storage bins in storage space II, both of which are plastic barrels; there are four storage bins in storage space III, all of which are plastic barrels.

[0125] Vinyl trichlorosilane is placed in storage space I; acrylic acid and ammonium persulfate are placed in two storage bins in storage space II; polyvinyl chloride, polyvinyl alcohol, ammonium persulfate and triazole dimercaptoamine salt are placed in the plastic barrel storage bin in storage space III.

[0126] After that, the air is extracted to make each storage bin in a vacuum-tight state. The above chemicals are kept at a low temperature by slowly releasing the liquid nitrogen in the cooling device. The metal product storage device is located above the chemical storage area, and there is an air inlet connected to the chemical storage area; the air inlet is opened at the same time, so that the metal product storage device is in a nitrogen atmosphere.

[0127] Turn on the cooling device of the mixing and stirring device, which is a cold water pipe surrounding the periphery of the mixing and stirring device, to perform cold water cooling in advance.

[0128] First, open the bottom opening of the vinyltrichlorosilane placement bin in the placement space I, which is directly connected to the mixing and stirring device, that is, when the opening is opened, the vinyltrichlorosilane falls into the mixing and stirring device; after the number of parts of vinyltrichlorosilane reaches 150 parts, close the opening; open the feed port of the mixing and stirring device, and inject 450 parts of water; turn on the agitator for stirring to obtain solution I.

[0129] The mixed and stirred solution I enters the coating device through the channel on the side wall of the mixing and stirring device, and the valve is controlled to make the solution I pass evenly and finally reach the spraying panel to achieve the first layer of spraying. After the first layer is sprayed, it is air-dried.

[0130] While the first layer is air-dried, the bottom opening of the acrylic acid placement bin in the placement space II is opened, and the opening is directly connected to the mixing and stirring device. After the number of acrylic acid portions reaches 20 portions, the opening is closed; the feed port of the mixing and stirring device is opened, and 180 portions of water are injected; the agitator is turned on for stirring and mixing evenly; then the bottom opening of the ammonium persulfate placement bin in the placement space II is opened to 1 portion, and mixing and stirring are performed to obtain solution II.

[0131] Then, solution II is quickly introduced into the coating device through the channel on the side wall of the mixing and stirring device, and the valve is controlled to make solution II pass evenly and finally reach the spraying panel to achieve the second layer of spraying. After the second layer is sprayed, it is air-dried.

[0132] While the second layer is air-dried, the bottom openings of the polyvinyl chloride placement bin and the polyvinyl alcohol placement bin in the placement space III are opened simultaneously, and 100 parts of polyvinyl chloride and 0.8 parts of polyvinyl alcohol are added, and then the openings are closed; the feed port of the mixing and stirring device is opened, and 120 parts of water are injected; the agitator is turned on for stirring and mixing evenly; then the openings at the bottom of the ammonium persulfate placement bin and the triazole dimercaptoamine salt placement bin in the placement space II are opened, and 0.1 parts of ammonium persulfate and 1 part of triazole dimercaptoamine salt are added, and mixed and stirred to obtain solution III.

[0133] Then, solution III is quickly passed into the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, solution III passes evenly and finally reaches the spraying panel to achieve the third layer of spraying.

[0134] Then, the heating device around the metal product placement device is used; the heating device is a hot water pipe surrounding the outer periphery of the mixing and stirring device, and the hot water is obtained by heating the water in the cold water pipe. The temperature around the metal product placement device is controlled to be 60°C, and the heating time is 60 minutes; then, until the temperature of the metal surface drops to room temperature, a maintenance structure with a three-layer structure (organic complex layer, hydrophilic layer and hydrophobic layer) on the metal product surface can be obtained, thereby achieving maintenance of the metal product.

[0135] By conducting a neutral salt spray test on the metal products after the above maintenance, no rust was found after 4000 hours; this shows that the metal surface has a complete organic complex layer, hydrophilic layer and hydrophobic layer, and the layers are cross-linked and combined with each other to form a stable network structure. The hydrophobic layer can reject most moisture intrusion, and the hydrophilic layer can firmly lock the moisture inside the metal and the moisture that penetrates into it to prevent it from extending to the metal layer; the organic complex layer complexes with the free iron in the metal to further prevent the free iron from oxidizing and rusting.

Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
