Description

Technical Field

[0001] This invention relates to the field of moisture-proofing and rust removal, and in particular to a moisture-proofing and rust-proofing treatment device and method for water conservancy and hydropower engineering equipment. Background Technology

[0002] The construction environment of water conservancy and hydropower projects is complex. Many construction equipment used in the process has poor moisture resistance. After the construction is completed, moisture-proof treatment is required for this part of the construction equipment. This type of equipment includes: drill bits, drill rods, wrenches, screwdrivers, etc. Drill bits, drill rods, wrenches, screwdrivers and other equipment are generally general-purpose equipment and are not specifically designed for water conservancy and hydropower projects. Therefore, the moisture resistance of this type of construction equipment is relatively poor and requires regular moisture-proof treatment.

[0003] Current technologies for moisture-proofing equipment use simple structures, typically involving a fan to dry the surface moisture. However, due to the complex environments at water conservancy and hydropower construction sites, equipment surfaces often accumulate large amounts of acid- and alkali-corrosive sludge and other contaminants. This sludge contains significant amounts of moisture and acid- and alkali-corrosive liquids, which are more difficult to evaporate than those on the equipment surface. Existing moisture-proofing and rust-proofing equipment generally only dries the visible moisture and acid- and alkali-corrosive liquids on the equipment surface, failing to remove the sludge. The sludge adhering to the equipment surface still contains a certain amount of moisture and acid- and alkali-corrosive liquids. This damp, corrosive sludge adheres to the equipment surface, causing the outer wall of the equipment to become damp, leading to corrosion and rust. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a moisture-proof and rust-proof treatment device and method for water conservancy and hydropower engineering equipment, which cleans, dries and prevents rust on the parts of water conservancy and hydropower engineering equipment, thereby reducing the likelihood of rust when the equipment is used in a humid environment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a moisture-proof and rust-proof treatment device for water conservancy and hydropower engineering equipment, including an ultrasonic vibration cleaning tank, a roller conveyor on one side of the ultrasonic vibration cleaning tank, multiple first hot air fans on the upper side of the frame on both sides of the roller conveyor, the air outlets of the first hot air fans facing the roller direction of the roller conveyor, an installation frame between the roller conveyor and the ultrasonic vibration cleaning tank, a transfer mechanism on the installation frame, the transfer mechanism including a drive gear, the shaft of the drive gear being rotatably mounted on the installation frame, the drive gear being driven by a drive mechanism, the drive mechanism driving the drive gear to rotate and transfer the cleaning basket to the ultrasonic vibration cleaning tank or above the roller conveyor, the upper end of a telescopic column being installed at the eccentric position of the drive gear, the lower end of the telescopic column being provided with a flipping mechanism, the flipping mechanism including an installation rod, the cleaning basket being rotatably mounted on the installation rod by a horizontal rotating shaft, the horizontal rotating shaft being driven by a flipping drive device.

[0006] In a preferred embodiment, the mounting frame includes a support plate and a support rod. The support plate is connected to the frame of the roller conveyor via the support rod, and the shaft of the drive gear is rotatably mounted on the support plate.

[0007] In a preferred embodiment, the telescopic column is a hydraulic cylinder or an electric push rod.

[0008] In a preferred embodiment, the drive mechanism includes a motor mounted on a mounting bracket, and the output end of the motor is provided with a drive gear that meshes with the drive gear.

[0009] In a preferred embodiment, the flipping drive device includes a drive motor mounted on a mounting rod, a drive sprocket on the output shaft of the drive motor, and a driven sprocket on a horizontal rotating shaft. The drive sprocket and the driven sprocket are driven by a chain.

[0010] In a preferred embodiment, a plurality of second hot air blowers are provided below the rollers of the roller conveyor. The air outlets of the second hot air blowers face upwards and are distributed along the conveying direction of the roller conveyor. The second hot air blowers are mounted on a connecting plate, and the connecting plate is connected to the frame of the roller conveyor.

[0011] In a preferred embodiment, the gap between two adjacent rollers in the roller conveyor is 10-15 cm.

[0012] This invention also provides a method for treating moisture-proof and rust-proof equipment for water conservancy and hydropower engineering, comprising the following steps:

[0013] S1. Place an appropriate amount of the equipment that needs to be moisture-proofed into the cleaning basket, turn on the motor, the drive gear rotates and drives the telescopic column and the cleaning basket to rotate synchronously. After the cleaning basket rotates to the top of the ultrasonic vibration cleaning tank, the motor stops driving, the telescopic column is turned on, the telescopic column extends downward to allow the cleaning basket to enter the ultrasonic vibration cleaning tank, inject rust-preventive cleaning agent into the ultrasonic vibration cleaning tank, and the equipment inside the cleaning basket is ultrasonically cleaned in the ultrasonic vibration cleaning tank.

[0014] S2. After the equipment is cleaned, start the telescopic column again. The telescopic column retracts, moving the cleaning basket above the ultrasonic vibration cleaning tank. Turn on the motor, and the drive gear rotates, causing the cleaning basket to rotate above the roller conveyor. The motor stops, the telescopic column extends, the height of the cleaning basket is adjusted, and the tilting mechanism is started. The drive motor drives the drive sprocket to rotate, and through chain transmission, the driven sprocket rotates synchronously, thereby driving the horizontal shaft to rotate, causing the cleaning basket to tilt and pour the cleaned equipment inside the cleaning basket onto the roller conveyor.

[0015] S3. The roller conveyor transports the cleaned equipment. The first hot air blower on both sides of the roller conveyor dries the equipment on the roller conveyor. The dried equipment is then unloaded through the roller conveyor, completing the moisture-proof treatment of the equipment.

[0016] In a preferred embodiment, in step S1, the rust-preventive cleaning agent comprises the following components in parts by weight: 7-8 parts polyvinyl alcohol, 3-5 parts sodium tripolyphosphate, 40-45 parts sodium dodecylbenzenesulfonate, 25-30 parts polyethylene glycol octylphenyl ether, 3-5 parts water-soluble nano-SiO2, and 0.5-1 parts rare earth cerium salt.

[0018] The present invention provides a moisture-proof and rust-proof treatment device and method for water conservancy and hydropower engineering equipment, which has the following beneficial effects:

[0019] 1. This invention combines cleaning and drying as a means of moisture prevention. After the surface of the equipment is cleaned and then air-dried, it will not become damp and rusty due to silt, thus solving the problems existing in the prior art.

[0020] 2. The tilting mechanism uses a sprocket and chain transmission structure to control the rotation and locking of the horizontal shaft. It is easy to operate and can also avoid the problem of water entering the drive motor and causing damage.

[0021] 3. The second hot air blower and the first hot air blower work together to thoroughly dry the equipment on the roller conveyor. This method is highly efficient and effective, and helps to improve the efficiency of moisture-proof and rust-proof treatment of the equipment.

[0022] 4. Based on existing rust-preventive cleaning agents, the formula of the rust-preventive cleaning agent has been improved, which can form a film on the surface of the equipment, and the equipment has a longer period of waterproof, moisture-proof and rust-proof function during use.

[0023] 5. Combining rust inhibitor cleaning agent, ultrasonic vibration cleaning structure, and conveyor drying can increase the adhesion of film-forming components in the rust inhibitor cleaning agent to the equipment surface, and dry the equipment in a short time, thereby increasing the film formation speed on the equipment surface and reducing the loss of film-forming components before film formation, resulting in the best possible film quality.

[0029] Example 1: As Figures 1-3 As shown, a moisture-proof and rust-proof treatment device for water conservancy and hydropower engineering equipment includes an ultrasonic vibration cleaning tank 1. A roller conveyor 2 is provided on one side of the ultrasonic vibration cleaning tank 1. Multiple first hot air blowers 3 are provided on the upper side of the frame 201 on both sides of the roller conveyor 2. The air outlets of the first hot air blowers 3 face the roller 202 of the roller conveyor 2. The first hot air blowers 3 are evenly distributed along the conveying direction of the roller conveyor 2. The roller conveyor 2 serves as the carrier of the hot air blowers. On the one hand, it is to disperse multiple equipment parts to be rust-proofed to improve the drying efficiency. On the other hand, it is to facilitate unloading.

[0030] A mounting frame 4 is provided between the roller conveyor 2 and the ultrasonic vibration cleaning tank 1. The mounting frame 4 is equipped with a transfer mechanism, which includes a drive gear 5. The drive mechanism rotates the drive gear 5, causing the cleaning basket 8 to rotate horizontally and transfer it above the ultrasonic vibration cleaning tank 1 or the roller conveyor 2. No manual transfer is required to move parts and equipment from the ultrasonic vibration cleaning tank 1 to the roller conveyor 2, making operation convenient, time-saving, and labor-saving. The transfer time is within 15 seconds, and there is no need to empty the equipment from the cleaning basket 8 during the transfer process. The transfer path is simple, and the loss of film-forming components adhering to the equipment surface is minimal during transfer. After rapid drying (drying time within 1 minute), a uniform film of a certain thickness forms on the equipment surface, providing significant moisture protection. This good moisture protection also results in good rust prevention.

[0031] In this embodiment, the mounting frame 4 includes a support plate 401 and a support rod 402. The support plate 401 is horizontally arranged and connected to the frame 201 of the roller conveyor 2 via the support rod 402. The shaft of the drive gear 5 is rotatably mounted on the support plate 401, and the drive gear 5 is located below the support plate 401 and is horizontally arranged. The upper end of the telescopic column 6 is installed at an eccentric position of the drive gear 5, and the lower end of the telescopic column 6 is provided with a flipping mechanism. The telescopic column 6 can extend and retract, thereby driving the flipping mechanism to move up and down. In this embodiment, the telescopic column 6 is a hydraulic cylinder or an electric push rod.

[0032] The telescopic column 6 is used to adjust the height of the cleaning basket 8, ensuring that the cleaning basket 8 can enter the ultrasonic vibration cleaning tank 1 while also having sufficient space to move during transport. The ultrasonic cleaning tank 1 in this invention provides excellent cleaning results and high efficiency, and can even clean irregularly shaped equipment. When the ultrasonic cleaning tank 1 is combined with a roller conveyor 2 equipped with a hot air blower, it effectively cleans and dries equipment used in water conservancy and hydropower projects, achieving optimal moisture-proof and rust-proof effects through the combination of cleaning and drying.

[0033] The tilting mechanism includes a mounting rod 7. The cleaning basket 8 is rotatably mounted on the mounting rod 7 via a horizontal rotating shaft 9 and bearings. The horizontal rotating shaft 9 is driven by a tilting drive device and is horizontally positioned. The cleaning basket 8 can tilt along the horizontal rotating shaft 9 in a vertical plane, facilitating the tilting and emptying of equipment parts from the cleaning basket 8. The cleaning basket 8 has a mesh-like perforated structure, which facilitates the drainage of rust-preventive cleaning agent from the cleaning basket 8.

[0034] In this embodiment, the driving mechanism includes a motor 10 mounted on the mounting frame 4. The output end of the motor 10 is provided with a drive gear 11, which meshes with the drive gear 5. Two sets of drive gears 5, telescopic columns 6, and flipping mechanisms are provided. Both sets of drive gears 5 mesh with the drive gear 11, and the two sets of telescopic columns 6 and flipping mechanisms are arranged in a row.

[0035] One drive gear 11 drives two drive gears 5 simultaneously, which improves equipment utilization and allows for the processing of more equipment at the same time. The drive gear 11 can also change the position of two cleaning baskets 8 at the same time.

[0036] The flipping drive device includes a drive motor 13 mounted on the mounting rod 7. The output shaft of the drive motor 13 is provided with a drive sprocket 14, and the horizontal rotating shaft 9 is provided with a driven sprocket 15. The drive sprocket 14 and the driven sprocket 15 are driven by a chain.

[0037] The drive motor 13 drives the active sprocket 14 and the driven sprocket 15 to rotate synchronously, thereby driving the horizontal rotating shaft 9, which enables the washing basket 8 to be flipped, making it convenient to transfer the equipment in the washing basket 8 to the roller conveyor 2.

[0038] Preferably, a plurality of second hot air blowers 16 are provided below the roller 202 of the roller conveyor 2. The air outlets of the second hot air blowers 16 face upward. The second hot air blowers 16 are distributed along the conveying direction of the roller conveyor 2. The second hot air blowers 16 are mounted on the connecting plate 12, and the connecting plate 12 is connected to the frame 201 of the roller conveyor 2.

[0039] The gap between two adjacent rollers 202 in the roller conveyor 2 is 10~15cm.

[0040] The second hot air blower 16 and the first hot air blower 3 work together to thoroughly dry the equipment on the roller conveyor 2. The drying time is less than 1 minute, which is highly efficient and effective, and helps to improve the equipment's moisture-proof and rust-proof efficiency.

[0041] The gap between two adjacent rollers 202 in roller conveyor 2 determines the size of the equipment that can be processed. If the gap between two adjacent rollers 202 in roller conveyor 2 is too large, it cannot process small-sized equipment, otherwise the equipment will fall out between the two adjacent rollers 202 in roller conveyor 2. If the gap between two adjacent rollers 202 in roller conveyor 2 is too small, the air volume passing through the gap will be small, which is not conducive to the drying of the bottom of the equipment.

[0042] A method for treating moisture-proof and rust-proof equipment for water conservancy and hydropower engineering projects includes the following steps:

[0043] S1. Place an appropriate amount of the equipment requiring moisture-proofing into the cleaning basket 8. Turn on the motor 10. The drive gear 11 rotates, driving the drive gear 5 to rotate. The drive gear 5 rotates, causing the telescopic column 6 and the cleaning basket 8 to rotate synchronously. After the cleaning basket 8 rotates above the ultrasonic vibration cleaning tank 1, the motor 10 stops driving. Open the telescopic column 6, which extends downwards to allow the cleaning basket 8 to enter the ultrasonic vibration cleaning tank 1. Inject rust-inhibiting cleaning agent into the ultrasonic vibration cleaning tank 1. The equipment inside the cleaning basket 8 undergoes ultrasonic cleaning in the ultrasonic vibration cleaning tank 1. The rust-inhibiting cleaning agent includes the following components in parts by weight: 7-8 parts polyvinyl alcohol, 3-5 parts sodium tripolyphosphate, 40-45 parts sodium dodecylbenzenesulfonate, 25-30 parts polyethylene glycol octylphenyl ether, 3-5 parts water-soluble nano SiO2, and 0.5-1 parts rare earth cerium salt.

[0044] In this embodiment, the rust-preventive cleaning agent includes 7 parts polyvinyl alcohol, 3 parts sodium tripolyphosphate, 40 parts sodium dodecylbenzenesulfonate, 25 parts polyethylene glycol octylphenyl ether, 3 parts water-soluble nano SiO2, and 0.5 parts rare earth cerium salt.

[0045] S2. After the equipment is cleaned, start the telescopic column 6 again. The telescopic column 6 retracts, moving the cleaning basket 8 above the ultrasonic vibration cleaning tank 1. Start the motor 10. The drive gear 11 rotates, driving the drive gear 5 to rotate, so that the cleaning basket 8 rotates above the roller conveyor 2. The motor 10 stops, the telescopic column 6 extends, the height of the cleaning basket 8 is adjusted, and the flipping mechanism is started. The drive motor 13 drives the drive sprocket 14 to rotate. Through chain transmission, the driven sprocket 15 rotates synchronously, thereby driving the horizontal rotating shaft 9 to rotate, so that the cleaning basket 8 flips and pours the cleaned equipment in the cleaning basket 8 onto the roller conveyor 2.

[0046] S3, Roller conveyor 2 transports the cleaned equipment, and the first hot air blower 3 on both sides of roller conveyor 2 dries the equipment on roller conveyor 2. The dried equipment is unloaded through roller conveyor 2 to complete the moisture-proof treatment of the equipment.

[0047] Before air-drying the equipment, this invention utilizes an ultrasonic cleaning tank to thoroughly clean the equipment. Under the action of the ultrasonic vibration cleaning equipment, the rust-preventive cleaning agent not only cleans the contaminants on the equipment, but the film-forming components in the rust-preventive cleaning agent also adhere to the surface of the equipment. The roller conveyor 2 with drying function disperses the equipment and can quickly dry each piece of equipment, allowing each piece of equipment to quickly form a film. The film adheres to the surface of the equipment and has the functions of moisture-proof, rust-proof, and corrosion-proof.

[0048] Polyvinyl alcohol, sodium tripolyphosphate, sodium dodecylbenzenesulfonate, polyethylene glycol octylphenyl ether, water-soluble nano-SiO2, and rare earth cerium salt are added to an appropriate amount of water in sequence while stirring. After stirring evenly, the mixture is immediately poured into an ultrasonic vibration cleaning tank and prepared for immediate use.

[0049] Example 2:

[0050] Unlike Example 1, the rust-preventive cleaning agent comprises 8 parts polyvinyl alcohol, 5 parts sodium tripolyphosphate, 45 parts sodium dodecylbenzenesulfonate, 30 parts polyethylene glycol octylphenyl ether, 5 parts water-soluble nano-SiO2, and 1 part rare earth cerium salt.

[0051] Example 3:

[0052] Based on Example 1, but differing from Example 1, the rust-preventive cleaning agent comprises 7.5 parts polyvinyl alcohol, 4 parts sodium tripolyphosphate, 42.5 parts sodium dodecylbenzenesulfonate, 27.5 parts polyethylene glycol octylphenyl ether, 4 parts water-soluble nano SiO2, and 0.8 parts rare earth cerium salt.

[0053] The following comparative proportions are used for illustration:

[0054] Comparative Example 1

[0055] Based on the formula in Example 3, a vibratory cleaning machine driven by an existing vibratory motor is used instead of the ultrasonic vibratory cleaning tank in Example 3 for cleaning the equipment, and the remaining steps are the same as those in Example 3.

[0056] Comparative Example 2

[0057] Based on Example 3, the difference from Example 3 is that the rust-preventive cleaning agent does not use polyvinyl alcohol.

[0058] Comparative Example 3

[0059] Based on Example 3, the difference from Example 3 is that the rust-preventive cleaning agent does not use sodium tripolyphosphate.

[0060] Comparative Example 4

[0061] Based on Example 3, the difference from Example 3 is that the rust-preventive cleaning agent does not use water-soluble nano-SiO2.

[0062] Comparative Example 5

[0063] Based on Example 3, the difference from Example 3 is that the rust-preventive cleaning agent does not use sodium dodecylbenzenesulfonate.

[0064] Comparative Example 6

[0065] Based on Example 3, the difference from Example 3 is that the rust-preventive cleaning agent does not use polyethylene glycol octylphenyl ether.

[0066] Comparative Example 7

[0067] Based on Example 3, the difference from Example 3 is that the rust-preventive cleaning agent does not use rare earth cerium salts.

[0068] The equipment treated with the moisture-proof and rust-proof methods described in Examples 1-3 and Comparative Examples 1-7 was subjected to acid and alkali corrosion tests, and the results are shown in Table 1.

[0069]

[0070] The method for detecting acid and alkali corrosion is as follows:

[0071] Acid corrosion test: Hydrochloric acid with concentrations of 20%, 30%, and 37% was used as the test acid. The equipment, after moisture-proofing treatment, was immersed in hydrochloric acid for 24 hours. The degree of corrosion on the equipment surface and the mass loss of the equipment were observed. The mass loss rate of the equipment was calculated as follows: mass loss rate = (m1-m2) / m1*100%, where m1 is the mass of the equipment before the acid-base test and m2 is the mass of the equipment after the acid-base test.

[0072] The method for alkaline corrosion testing is as follows: using sodium hydroxide solutions with concentrations of 25%, 30%, and 40% as test alkalis, the equipment, after moisture-proofing treatment, is immersed in the sodium hydroxide solution for 24 hours. The degree of corrosion on the equipment surface and the equipment mass loss are observed, and the equipment mass loss rate is calculated as follows: Mass loss rate = (m1-m2) / m1*100%, where m1 is the mass of the equipment before acid and alkali testing, and m2 is the mass of the equipment after acid and alkali testing.

[0073] In Table 1, mild corrosion is characterized by small spots on the equipment surface, a slightly rough feel, and a quality loss rate of less than 1%. Moderate corrosion is characterized by more obvious corrosion on the equipment surface, large spot coverage area, pitted feel, and a quality loss rate between 1% and 2%.

[0074] The ultrasonic vibration cleaning structure not only cleans the equipment surface thoroughly, but also ensures that all parts of the equipment come into full contact with the rust-preventive cleaning agent under the action of ultrasonic vibration cleaning. After contact with the rust-preventive cleaning agent components, a uniform film can be formed on the equipment surface. Comparing Example 3 and Comparative Example 1, it can be seen that compared with the existing vibration motor drive, the ultrasonic vibration cleaning structure produces a film with better acid and alkali resistance after the equipment is cleaned, exhibiting excellent rust prevention function in acidic and alkaline environments. In contrast, compared with Examples 1-3 and Comparative Examples 2-4, the absence of any film-forming component results in a film with poor acid resistance. The alkaline corrosion resistance is very poor. As can be seen from Examples 1-3 and Comparative Examples 5-6, the films formed using a single surfactant have very poor acid and alkali corrosion resistance. As can be seen from Examples 1-3 and Comparative Example 7, the film formed on the equipment surface has poor acid and alkali corrosion resistance when rare earth cerium salt is missing. Rare earth cerium salt can improve the adhesion of film-forming components to the equipment surface. When rare earth cerium salt is missing, the amount of film-forming components adhering to the equipment surface is small, and the film formed is easy to fall off. When acid and alkali corrosion tests were performed, it was found that after the equipment in Comparative Example 7 was immersed in acid and alkali for several hours, flocculent structures appeared in the solution, indicating that the film on the equipment surface had partially fallen off.

[0075] This invention provides moisture protection to equipment by forming a film on the equipment surface. This not only achieves the effect of moisture protection but also prevents rust, giving the equipment a certain degree of resistance to acid corrosion. Once the equipment is not corroded by acid or alkaline water, its surface is unlikely to rust. Therefore, this invention can provide moisture protection and rust prevention for equipment.

[0076] The equipment treated with the moisture-proof and rust-proof methods described in Examples 1-3 and Comparative Examples 1-7 was subjected to waterproof and wear-resistant tests. The test results are shown in Table 2.

[0077] The waterproofing test method is as follows: Place the regularly shaped equipment of Examples 1-3 and Comparative Examples 1-7, which have undergone moisture-proof and rust-proof treatment, in a spray chamber, rinse the equipment with water for 1 minute, and observe the degree of wetting on the surface of the equipment. Equipment with poor waterproofing will have a large area of ​​wet water stains on its surface, while equipment with good waterproofing performance will only have a small amount of water droplets on its surface.

[0078] The method for wear resistance testing is as follows: Referring to the dry abrasion test method, the regularly shaped devices of Examples 1-3 and Comparative Examples 1-7, after moisture-proof and rust-proof treatment, are placed on a wear testing machine with good similarity. Under the same parameters, the same friction components are used to rub the corresponding devices. After rubbing for 3 minutes, the mass wear rate of the device is calculated. Mass wear rate = (mass of the device before wear resistance test M3 - mass of the device after wear resistance test M4) / M3 * 100%.

[0079] Table 2. Test results of waterproofing and abrasion resistance of the equipment.

[0080] degree of wetting Mass wear rate Example 1 There are a few water droplets on the surface, but no wetting water stains. 0.01% Example 2 There are a few water droplets on the surface, but no wetting water stains. 0 Example 3 There are a few water droplets on the surface, but no wetting water stains. 0 Comparative Example 1 There are a few water droplets and small water stains on the surface. 0.06% Comparative Example 2 There are a few water droplets on the surface, but no wetting water stains. 0.02% Comparative Example 3 There are a few water droplets on the surface, but no wetting water stains. 0.04% Comparative Example 4 There are a few water droplets on the surface, but no wetting water stains. 0.02% Comparative Example 5 There are a few water droplets and small water stains on the surface. 0.08% Comparative Example 6 There are a few water droplets and small water stains on the surface. 0.1% Comparative Example 7 There were multiple damp water stains. 0.2%

[0081] As shown in Table 2, the equipment treated by this invention exhibits good waterproof and wear-resistant properties. The equipment can be stored dry with good moisture-proofing during storage, and also provides good moisture-proofing and rust-proofing during use. The wear resistance of the equipment surface depends on the quality of the surface film, which is affected not only by the film's own strength, wear resistance, and corrosion resistance, but also by various factors during the film-forming process, such as film thickness and uniformity. The ultrasonic cleaning structure, the transport-type drying structure, and the transfer structure between them in this invention all affect the adhesion amount and distribution uniformity of the film-forming components on the equipment surface. Therefore, through various improvements, this invention enables the formation of a uniform and durable film on the equipment surface in a short time, providing good waterproof, moisture-proof, rust-proof, and wear-resistant properties. Considering the material usage cost, Example 3 of this invention represents the optimal formulation.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
