Description

Technical Field

[0001] This invention relates to the field of rust-preventive impregnation, and more particularly to a rust-preventive impregnation method and equipment. Background Technology

[0002] Iron products are frequently used in daily life. After prolonged contact with air, they become corroded due to the presence of corrosive substances in the air, which affects their normal use.

[0003] To make iron products resistant to corrosion, they are usually subjected to nitriding, oxidation, and anti-corrosion wetting; among them, anti-corrosion wetting is the process of coating the outer surface of iron products with anti-rust liquid.

[0004] When applying anti-corrosion impregnation to iron products, the coating has the best anti-rust effect because the anti-rust solution has an optimal operating temperature. However, in cold weather, the anti-rust effect of the coated iron products may be poor. Summary of the Invention

[0011] The rust-preventive impregnation device provided by the present invention preferably includes a vertical moving mechanism comprising two cylinders and two connecting parts; the two connecting parts are respectively located on both sides of the impregnation tank; The connecting component includes a vertical component and a horizontal component; one end of the vertical component is fixed to the upper surface of the lifting plate, and the other end is fixed to the horizontal component; The telescopic rod of the cylinder is set upward; one cylinder corresponds to one connector, and the telescopic rod of the cylinder is fixed to the horizontal member.

[0012] The rust-preventive impregnation device provided by the present invention preferably includes a heating mechanism comprising a water tank and a heater; the heater is disposed inside the water tank. The temperature control mechanism also includes a water pump; The water tank has a second inlet and a second outlet; the first inlet is connected to the drain port of the water pump; the second outlet is connected to the inlet of the water pump; and the first outlet is connected to the second inlet.

[0013] The rust-preventive immersion device provided by the present invention preferably includes a water level sensor in the water tank; the water tank also has a third water inlet; a valve is provided at the third water inlet; and the water level sensor is electrically connected to the valve.

[0014] The rust-preventive impregnation device provided by the present invention preferably includes a coil comprising a plurality of straight pipes and a plurality of connecting pipes; the two opposite side walls of the first inner cavity are respectively designated as the first side wall and the second side wall, and the bottom side wall between the first side wall and the second side wall is designated as the third side wall; all the straight pipes are evenly laid on the first side wall, the second side wall, and the third side wall; the axes of all the straight pipes are arranged in parallel; two adjacent straight pipes are connected by the connecting pipes; the direction of the third side wall toward the first side wall or the second side wall is designated as the outer side, and the pipe openings of the two outer straight pipes are respectively designated as the first inlet and the first outlet.

[0015] The rust-preventive impregnation device provided by the present invention preferably further includes a plurality of magnets; the magnets are disposed on the side wall of the impregnation tank.

[0016] The above technical solution has the following advantages or beneficial effects: The rust-preventive impregnation method and equipment provided by this invention, in step S101, since the rust-preventive liquid has an optimal operating temperature, when it is at the optimal operating temperature, applying it to the surface of iron products can achieve the best rust-preventive effect. Therefore, when impregnating iron products with rust prevention, it is necessary to ensure that the temperature of the rust-preventive liquid is uniform and constant. By setting the flow position of the heat exchange medium, the heat exchange medium surrounds the impregnation tank and exchanges heat with the rust-preventive liquid in the impregnation tank. The surrounding heat exchange method can effectively improve the heating efficiency of the rust-preventive liquid, prevent the rust-preventive liquid from cooling down too quickly, and maintain the temperature of the rust-preventive liquid. At the same time, compared with placing a single heat source in the impregnation tank to heat the rust-preventive liquid, the surrounding heat exchange method can effectively prevent the local rust-preventive liquid temperature from being too high and the edge rust-preventive liquid temperature from being too low, so that the rust-preventive liquid temperature is uniform. In step S102, since different rust inhibitors have different optimal operating temperatures, it is necessary to preset the heating temperature of the rust inhibitor. A constant-temperature heating heat exchange medium is used, that is, the heat exchange medium is kept at a constant temperature. By keeping the temperature of the heat exchange medium at its optimal operating temperature, the temperature of the rust inhibitor that exchanges heat with the heat exchange medium can also be kept at its optimal operating temperature. By heating the heat exchange medium first and then heating the rust inhibitor by the heat exchange medium, the problem of uneven heat distribution caused by heating from a single heat source can be effectively avoided, ensuring that the temperature of the heat exchange medium is constant, thereby ensuring that the rust inhibitor is heated at a constant temperature and preventing the local temperature of the rust inhibitor from far exceeding the optimal operating temperature of the rust inhibitor, which would lead to the failure of the rust inhibitor. In step S103, the iron product is placed in the immersion tank, and the immersion time is preset. This immersion time is affected by the viscosity of the rust-preventive liquid and the oscillation frequency. The iron product is then vibrated up and down in the rust-preventive liquid. At this time, the iron product must be completely immersed in the rust-preventive liquid to ensure full contact between the iron product and the rust-preventive liquid. As the iron product is immersed in the rust-preventive liquid, the air on the surface of the iron product is gradually replaced by the rust-preventive liquid. When the air is compressed, it is easy to generate bubbles. These bubbles isolate the rust-preventive liquid from contacting the surface of the iron product, thus affecting the immersion quality of the iron product. By vibrating the iron product up and down, the bubbles generated on the surface of the iron product can be removed, allowing the rust-preventive liquid to fully contact the surface of the iron product and improving the immersion quality of the iron product. At the same time, during the up and down vibration of the iron product, the rust-preventive liquid in the middle part can be driven to flow towards the edge, promoting the flow of the rust-preventive liquid in the immersion tank and further improving the heating efficiency and temperature uniformity of the rust-preventive liquid. In step S104, after the oscillation is complete, the iron product is taken out of the immersion tank and the rust-preventive liquid on the surface of the iron product is drained, thus completing the rust-preventive immersion operation on the iron product.

[0022] Figure 5 This is a top view cross-sectional schematic diagram of the rust-preventive impregnation equipment provided in Embodiment 2 of the present invention. Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but these are not intended to limit the scope of the invention.

[0024] Example 1: like Figure 1 As shown, Embodiment 1 of the present invention provides a rust-preventive impregnation method, which includes the following steps: S101: Put the rust inhibitor into the immersion tank and exchange heat through the heat exchange medium surrounding the immersion tank; S102: Preset heating temperature, constant temperature heating of heat exchange medium, maintaining the rust inhibitor at the preset heating temperature; S103: Place the iron product into the immersion tank; preset the immersion time, and shake the iron product up and down in the rust-preventive liquid during the preset immersion time; S104: After the shaking is complete, remove the iron products from the immersion tank and drain the rust-preventive liquid from the surface of the iron products.

[0025] The rust-preventive impregnation method provided by this invention, in step S101, since the rust-preventive liquid has an optimal operating temperature, applying it to the surface of iron products at the optimal operating temperature can achieve the best rust-preventive effect. Therefore, when impregnating iron products with rust prevention, it is necessary to ensure that the temperature of the rust-preventive liquid is uniform and constant. By setting the flow position of the heat exchange medium, the heat exchange medium surrounds the impregnation tank and exchanges heat with the rust-preventive liquid in the impregnation tank. The surrounding heat exchange method can effectively improve the heating efficiency of the rust-preventive liquid, prevent the rust-preventive liquid from cooling down too quickly, and maintain the temperature of the rust-preventive liquid. At the same time, compared with placing a single heat source in the impregnation tank to heat the rust-preventive liquid, the surrounding heat exchange method can effectively prevent the local rust-preventive liquid temperature from being too high and the edge rust-preventive liquid temperature from being too low, so that the rust-preventive liquid temperature is uniform. In step S102, since different rust inhibitors have different optimal operating temperatures, it is necessary to preset the heating temperature of the rust inhibitor. A constant-temperature heating heat exchange medium is used, that is, the heat exchange medium is kept at a constant temperature. By keeping the temperature of the heat exchange medium at its optimal operating temperature, the temperature of the rust inhibitor that exchanges heat with the heat exchange medium can also be kept at its optimal operating temperature. By heating the heat exchange medium first and then heating the rust inhibitor by the heat exchange medium, the problem of uneven heat distribution caused by heating from a single heat source can be effectively avoided, ensuring that the temperature of the heat exchange medium is constant, thereby ensuring that the rust inhibitor is heated at a constant temperature and preventing the local temperature of the rust inhibitor from far exceeding the optimal operating temperature of the rust inhibitor, which would lead to the failure of the rust inhibitor. In step S103, the iron product is placed in the immersion tank, and the immersion time is preset. This immersion time is affected by the viscosity of the rust-preventive liquid and the oscillation frequency. The iron product is then vibrated up and down in the rust-preventive liquid. At this time, the iron product must be completely immersed in the rust-preventive liquid to ensure full contact between the iron product and the rust-preventive liquid. As the iron product is immersed in the rust-preventive liquid, the air on the surface of the iron product is gradually replaced by the rust-preventive liquid. When the air is compressed, it is easy to generate bubbles. These bubbles isolate the rust-preventive liquid from contacting the surface of the iron product, thus affecting the immersion quality of the iron product. By vibrating the iron product up and down, the bubbles generated on the surface of the iron product can be removed, allowing the rust-preventive liquid to fully contact the surface of the iron product and improving the immersion quality of the iron product. At the same time, during the up and down vibration of the iron product, the rust-preventive liquid in the middle part can be driven to flow towards the edge, promoting the flow of the rust-preventive liquid in the immersion tank and further improving the heating efficiency and temperature uniformity of the rust-preventive liquid. In step S104, after the oscillation is complete, the iron product is taken out of the immersion tank and the rust-preventive liquid on the surface of the iron product is drained, thus completing the rust-preventive immersion operation on the iron product.

[0026] The rust-preventive impregnation method provided by the present invention preferably uses a water-based rust inhibitor or a rust-preventive oil in step S101.

[0027] The rust-preventive impregnation method provided by the present invention preferably includes step S103 as follows: placing the iron product into the impregnation tank; adsorbing iron powder on the surface of the iron product and in the rust-preventive liquid using a magnet; setting a preset impregnation time, and oscillating the iron product up and down in the rust-preventive liquid during the preset impregnation time; Since iron powder may remain on the surface of iron products after processing, if such products are placed in an immersion tank, some of the iron powder will still adhere to the surface, while the rest will float in the rust-preventive solution. If the iron powder adheres to the surface of the iron product, it will prevent the rust-preventive solution from contacting the surface. Magnets can prevent the iron powder adhering to the iron product or floating in the rust-preventive solution from affecting the immersion effect. Magnets attract the iron powder, allowing the rust-preventive solution to fully contact the surface of the iron product, thus improving the immersion quality. Furthermore, the attraction of iron powder by magnets makes it easier for users to recover and clean it.

[0028] The rust-preventive impregnation method provided by the present invention preferably includes, in step S104, after "removing the iron products from the impregnation tank", filtering the rust-preventive liquid and cleaning the adsorbed iron powder. When applying rust-proofing impregnation to iron products in multiple batches, magnets cannot attract too much iron powder. Therefore, after one or more rust-proofing impregnation operations, the rust-proofing solution should be filtered and the iron powder adsorbed on the magnet should be cleaned to effectively maintain the rust-proofing effect of the impregnated iron products.

[0029] Example 2: like Figures 2-3 As shown, Embodiment 2 of the present invention provides a rust-proof impregnation device that applies the rust-proof impregnation method in Embodiment 1 of the present invention, including an impregnation tank 1, a lifting plate 2, a vertical moving mechanism 3 and a constant temperature mechanism 4; The immersion tank 1 is provided with a first inner cavity 11; the top of the immersion tank 1 is provided with a first opening 12; the first opening 12 communicates with the first inner cavity 11; the lifting plate 2 is horizontally arranged; the lifting plate 2 is located in the first inner cavity 11; the vertical moving mechanism 3 drives the lifting plate 2 to move in the vertical direction; The constant temperature mechanism 4 includes a coil 41 and a heating mechanism 42; The coil 41 is distributed around the side wall of the first inner cavity 11; the coil 41 is provided with a first water inlet 411 and a first water outlet 412; the first water inlet 411 and the first water outlet 412 are connected; the heat exchange medium in the coil 41 maintains its temperature through the heating mechanism 42.

[0030] When using the rust-preventive impregnation equipment provided in Embodiment 2 of the present invention, rust-preventive liquid is added into the first inner cavity 11 through the first opening 12; the heat exchange medium is heated to a preset temperature by the heating mechanism 42, so that the heated heat exchange medium enters the coil 41 from the first inlet 411 and leaves the coil 41 from the first outlet 412, forming a cycle. When the heat exchange medium flows in the coil 41, the coil 41 exchanges heat with the rust-preventive liquid in the impregnation tank 1; the first inlet 411 and the first outlet 412 are connected, and the heat exchange medium can be recycled; the workpiece to be impregnated is placed on the lifting plate 2, where the workpiece refers to iron products, the required impregnation time of the workpiece is set, and the lifting plate 2 is driven to oscillate up and down in the first inner cavity 11 by the vertical moving mechanism 3; after the impregnation time is over, the lifting plate 2 is raised to the first opening 12 by the vertical moving mechanism 3, and the workpiece on the lifting plate 2 is taken out.

[0031] The rust-preventive impregnation device provided in Embodiment 2 of the present invention includes an impregnation tank 1, a lifting plate 2, a vertical moving mechanism 3, and a constant temperature mechanism 4. The vertical moving mechanism 3 drives the lifting plate 2 to vibrate up and down within the first inner cavity 11 of the impregnation tank 1, thereby impregnating the workpiece placed on the lifting plate 2. Since the rust-preventive liquid has an optimal operating temperature, in order to ensure the workpiece has the best rust-preventive effect after impregnation, it is also necessary to control the temperature of the rust-preventive liquid. For this purpose, the constant temperature mechanism 4 is used to heat the rust-preventive liquid at a constant temperature. Specifically, the constant temperature mechanism 4 includes a coil 41 and a heating mechanism. 42; The coil 41 is distributed around the side wall of the first inner cavity 11. A heat exchange medium of a specified temperature flows inside the coil 41. The coil 41 exchanges heat with the rust inhibitor to maintain the temperature of the rust inhibitor. In order to maintain the temperature of the heat exchange medium inside the coil 41, the coil 41 is provided with a first inlet 411 and a first outlet 412. The first inlet 411 and the first outlet 412 are connected so that the heat exchange medium can circulate continuously inside the coil 41. At the same time, the heat exchange medium inside the coil 41 is continuously heated by the heating mechanism 42 to maintain the temperature of the heat exchange medium. Furthermore, since the coil 41 is distributed around the side wall of the first inner cavity 11, the coil 41 can provide circumferential heating for the rust-preventive liquid, thereby improving the heating efficiency of the rust-preventive liquid. At the same time, the lifting plate 2 vibrates up and down within the first inner cavity 11, which can drive the rust-preventive liquid in the middle part to flow towards the edge, further improving the heating efficiency of the rust-preventive liquid. Compared with using a single heat source for heating in the first inner cavity 11, the circumferential heating method can make the rust-preventive liquid heat evenly, avoiding the workpiece after immersion from failing to achieve the best rust-preventive effect. Furthermore, when the workpiece is immersed in the rust inhibitor, the air on the surface of the workpiece is gradually replaced by the rust inhibitor. When the air is squeezed, it is easy to generate bubbles, which affects the immersion quality of the workpiece. Therefore, by using the lifting plate 2 to vibrate up and down in the first inner cavity 11, the bubbles generated on the surface of the workpiece can be removed, so that the rust inhibitor can fully contact the surface of the workpiece and improve the immersion quality of the workpiece. In existing technologies, the rust-preventive liquid has an optimal operating temperature. However, in colder weather conditions, the rust-preventive effect on coated iron products may be poor. The rust-preventive immersion equipment provided in Embodiment 2 of this invention uses a constant temperature mechanism 4 to heat the rust-preventive liquid in the immersion tank 1 at a constant temperature, thereby maintaining the temperature of the rust-preventive liquid. This allows the iron products to be immersed in the rust-preventive liquid at a suitable temperature, thus giving the workpiece the best rust-preventive effect.

[0032] like Figures 2-3 As shown, the rust-preventive impregnation equipment provided in Embodiment 2 of the present invention is preferably configured such that, in order to drive the lifting plate 2 to move vertically by means of the vertical moving mechanism 3, the vertical moving mechanism 3 specifically includes two cylinders 31 and two connecting parts 32. The connecting parts 32 are used to connect the lifting plate 2 and the telescopic rods of the cylinders 31. In order to enable the cylinders 31 to stably lift the lifting plate 2, the two connecting parts 32 are respectively located on both sides of the impregnation tank 1. To connect the lifting plate 2 and the telescopic rod of the cylinder 31, more specifically, the connecting member 32 includes a vertical member 321 and a horizontal member 322. One end of the vertical member 321 is fixed to the upper surface of the lifting plate 2, and the other end is fixed to the horizontal member 322. The telescopic rod of the cylinder 31 is set upward, and one cylinder 31 corresponds to one connecting member 32. The telescopic rod of the cylinder 31 is fixed to the horizontal member 322. If the telescopic rod of the cylinder 31 extends upward, the telescopic rod pulls the horizontal member 322 to move upward. Since the horizontal member 322 is fixed to the vertical member 321, the lifting plate 2 moves upward. If the telescopic rod of the cylinder 31 retracts downward, the telescopic rod pulls the horizontal member 322 to move downward. Since the horizontal member 322 is fixed to the vertical member 321, the lifting plate 2 moves downward.

[0033] like Figures 2-3As shown, the rust-preventive impregnation device provided in Embodiment 2 of the present invention preferably includes several placement frames 5, which are placed on the upper surface of the lifting plate 2 to protect the workpiece and prevent it from falling off the lifting plate 2 during vertical vibration. To facilitate the placement of the workpiece into the placement frame 5, the placement frame 5 is provided with a second inner cavity 51 and a second opening 52 at the top of the placement frame 5, which communicates with the second inner cavity 51. Workers can place the workpiece into the second inner cavity 51 through the second opening 52. The side wall of the placement frame 5 also has a limiting effect on the workpiece and protects it from wear during vertical vibration. Since the workpiece needs to be completely immersed in the rust-preventive liquid, there will be residual rust-preventive liquid in the placement frame 5 containing the workpiece. To avoid residual rust-preventive liquid in the placement frame 5 and improve the utilization rate of the rust-preventive liquid, several drainage holes 53 are provided on the side wall of the placement frame 5. When the placement frame 5 rises with the lifting plate 2 to the first opening 12, the residual rust-preventive liquid in the placement frame 5 leaves through the drainage holes 53.

[0034] like Figure 3 As shown, the rust-preventive impregnation equipment provided in Embodiment 2 of the present invention preferably includes a hollow frame 21 and several separators 22 to avoid large resistance when the lifting plate 2 vibrates up and down in the rust-preventive liquid. The separators 22 are evenly distributed on the hollow frame 21, and the separators 22 further separate the hollow frame 21 with large gaps to prevent the workpiece from falling through the gaps. When the lifting plate 2 vibrates up and down in the rust-preventive liquid, the rust-preventive liquid can flow through the gaps between the hollow frame 21 and the separators 22, reducing its contact area with the lifting plate 2, thereby reducing the resistance generated when the lifting plate 2 vibrates up and down, avoiding wear of the vertical moving mechanism 3 when driving the lifting plate 2, and extending the service life of the rust-preventive impregnation equipment. Furthermore, by using the lifting plate 2 with the hollow frame 21 separated by the separators 22, the rust-preventive liquid can be prevented from remaining on the lifting plate 2, improving the utilization rate of the rust-preventive liquid.

[0035] like Figure 3 As shown, the rust-proof impregnation equipment provided in Embodiment 2 of the present invention is preferably designed to achieve constant temperature heating of the heat exchange medium in the coil 41 by the heating mechanism 42. Specifically, the heating mechanism 42 includes a water tank 421 and a heater. The heater is disposed in the water tank 421, and the heat exchange medium in the water tank 421 is heated by the heater. In order to enable the heat exchange medium in the coil 41 to be circulated, the thermostatic mechanism 4 also includes a water pump 43; More specifically, the water tank 421 has a second inlet 4211 and a second outlet 4212. The first inlet 411 is connected to the drain port of the water pump 43, the second outlet 4212 is connected to the inlet of the water pump 43, and the first outlet 412 is connected to the second inlet 4211. The water pump 43 pumps the heat exchange medium in the water tank 421 into the coil 41 and drives the water in the coil 41 to flow back into the water tank 421.

[0036] like Figure 3 As shown, in the rust-proof impregnation device provided in Embodiment 2 of the present invention, preferably, since the heat exchange medium may be lost during use, resulting in the heat exchange medium in the water tank 421 being unable to be pumped into the coil 41, a water level sensor is provided in the water tank 421 to monitor the water level in the water tank 421. The water tank 421 is also provided with a third water inlet 4213 to replenish the heat exchange medium. A valve 42131 is provided at the third water inlet 4213 to control the inflow of the heat exchange medium. The water level sensor is electrically connected to the valve 42131. If the water level in the water tank 421 is too low, the water level sensor controls the valve 42131 to open, so that the heat exchange medium enters the water tank 421 from the third water inlet 4213.

[0037] like Figure 4 As shown, the rust-proof impregnation device provided in Embodiment 2 of the present invention, preferably, in order to achieve the distribution of the coil 41 around the sidewall of the first inner cavity 11, specifically, the coil 41 includes a plurality of straight pipes 413 and a plurality of connecting pipes 414; the two opposite sidewalls of the first inner cavity 11 are respectively designated as the first sidewall 111 and the second sidewall 112, and the bottom sidewall between the first sidewall 111 and the second sidewall 112 is designated as the third sidewall 113; all the straight pipes 413 are evenly laid on the first sidewall 111, the second sidewall 112 and the third sidewall 113, and all the straight pipes 414 are... The axes of 13 are arranged in parallel so that the coil 41 exchanges heat with the rust inhibitor from the side wall and bottom of the first inner cavity 11, thereby achieving circumferential heating of the rust inhibitor in the first inner cavity 11; two adjacent straight pipes 413 are connected by a connecting pipe 414 so that the heat exchange medium can flow in multiple straight pipes 413; the direction from the third side wall 113 toward the first side wall 111 or the second side wall 112 is taken as the outer side, and the pipe openings of the two outer straight pipes 413 are respectively used as the first water inlet 411 and the first water outlet 412, for connecting to the water tank 421 and the water pump 43.

[0038] The rust-preventive impregnation device provided in Embodiment 2 of the present invention preferably further includes several magnets, which are disposed on the side wall of the impregnation tank 1 to adsorb residual iron powder on the workpiece. Since iron powder may remain on the surface of the workpiece after processing, if a workpiece with iron powder enters the first inner cavity 11, some of the iron powder will still adhere to the surface of the workpiece, while the other part will float in the rust-preventive liquid. By setting the magnets, the iron powder adhering to the workpiece or floating in the rust-preventive liquid can be prevented from affecting the impregnation effect of the workpiece. The magnets adsorb the iron powder, so that the rust-preventive liquid can fully contact the surface of the workpiece, thereby improving the impregnation quality of the workpiece. Furthermore, the magnets adsorb the iron powder onto the side wall of the impregnation tank 1, which facilitates the recovery and cleaning of the iron powder by the user.

[0039] like Figure 5 As shown, the rust-preventive impregnation equipment provided in Embodiment 2 of the present invention is preferably designed so that if multiple batches of workpieces use the same part of rust-preventive liquid, the effect of the rust-preventive liquid may be poor and the rust-preventive liquid needs to be replaced. For this reason, the impregnation tank 1 is also provided with a first discharge pipe 13, which is connected to the first inner cavity 11 and can be opened and closed.

[0040] like Figure 5 As shown, in the rust-preventive impregnation equipment provided in Embodiment 2 of the present invention, preferably, the water tank 421 is provided with a second discharge pipe 4214 for replacing the heat exchange medium in the water tank 421, and the second discharge pipe 4214 can be opened and closed.

[0041] The rust-preventive impregnation device provided in Embodiment 2 of the present invention preferably includes a heating mechanism 42 further comprising a temperature sensor and a buzzer. The temperature sensor and the buzzer are electrically connected. The temperature sensor measures the temperature of the heat exchange medium in the water tank 421. If the temperature of the heat exchange medium exceeds the set value, the buzzer will sound an alarm. Furthermore, the temperature sensor is electrically connected to the heater. If the temperature of the heat exchange medium exceeds the set value, the heater will stop heating; otherwise, the heating state will be maintained.

[0042] The rust-preventive impregnation device provided in Embodiment 2 of the present invention preferably includes an impregnation tank 1 further comprising a cover for covering the first opening 12 to prevent dust and other contaminants from entering the first inner cavity 11 during production stoppage.

[0043] In summary, the rust-preventive impregnation method and equipment provided by the present invention can solve the problem that the rust-preventive liquid has an optimal operating temperature, and the rust-preventive effect of the coated iron products may be poor in cold weather; and achieve constant temperature impregnation of iron products.
