Description

Technical Field

[0001] This invention relates to the field of coating technology, and in particular to a method for preparing anti-condensation coatings, a method for using anti-condensation coatings, and an apparatus for applying anti-condensation coatings. Background Technology

[0002] Paint is a commonly used product. It is applied to the surface of objects to protect them, as well as to decorate, prevent corrosion, and reduce moisture on the surface of objects.

[0003] In electrical equipment, applying a coating to the outside of electrical components is particularly important for protection. For example, coating circuit breakers reduces arcing and increases creepage distance; coating cables extends cable life and reduces cable loss. Manufacturers generally strive to reduce condensation on electrical equipment, as this is beneficial for its protection. For cables, reducing condensation also reduces the load on poles. Although the presence of a coating layer helps reduce condensation, current technology does not yet offer coatings with particularly good anti-condensation effects. Existing coatings need further improvement in their anti-condensation performance, i.e., the production of coatings with better anti-condensation effects. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a coating with better anti-condensation effect—an anti-condensation coating—as well as a method for using this anti-condensation coating and an anti-condensation coating application device.

[0005] The technical solution of the anti-condensation coating of the present invention is as follows: the anti-condensation coating includes an independently packaged coating body, and also includes an independently packaged surface spraying powder, wherein the surface spraying powder includes nano-sized boron fiber powder, nano-sized graphene powder and nano-sized metal oxide powder, wherein the nano-sized metal oxide powder is at least one of nano-sized cerium oxide powder, nano-sized yttrium oxide powder and nano-sized neodymium oxide powder.

[0006] Furthermore, the surface coating powder has been soaked in alkaline solution and then dried.

[0007] Furthermore, the mass ratio of nanoscale boron fiber powder, nanoscale graphene powder, and nanoscale metal oxide powder is 1–1.2:1–1.2:1–1.5.

[0008] Furthermore, the nanoscale metal oxide powder includes nanoscale cerium oxide powder, nanoscale yttrium oxide powder, and nanoscale neodymium oxide powder; the mass ratio of the nanoscale cerium oxide powder, nanoscale yttrium oxide powder, and nanoscale neodymium oxide powder is 1-1.2:1-1.2:1-1.2.

[0009] The technical solution of the anti-condensation coating of the present invention is as follows: it includes the following steps:

[0010] S1. The paint body is sprayed onto the surface of the object to form a non-condensing paint layer;

[0011] S2. Spray the surface coating powder onto the non-condensing paint layer and vibrate;

[0012] Furthermore, during S1 spraying, the temperature of the object surface is 10-15°C lower than the temperature of the anti-condensation coating.

[0013] Furthermore, the surface temperature of the object is 10-15°C, and the temperature of the anti-condensation coating is 20-25°C.

[0014] The technical solution of the anti-condensation coating device of the present invention is as follows: The anti-condensation coating device is characterized by comprising a frame, on which are a first roller wound with a cable raw material and a second roller wound with a coated cable. The cable raw material forms a coating path from the first roller to the second roller. A first coating chamber for spraying the coating body onto the outside of the cable raw material is installed on the frame. A second coating chamber for spraying powder onto the non-condensing coating layer of the cable is also installed on the frame. The first and second coating chambers have an outlet and an inlet, respectively. The coating path first enters the first coating chamber and then the second coating chamber through the inlet and outlet. A first nozzle for spraying the coating body onto the cable raw material is located in the first coating chamber. The first nozzle is connected to a conveying pipe for the coating body. This conveying pipe is the first conveying pipe. The first nozzle faces the coating path in the first coating chamber. A second nozzle for spraying powder onto the non-condensing coating layer of the cable is located in the second coating chamber. The second nozzle faces the coating path in the second coating chamber.

[0015] Furthermore, the cable travels from back to front along the coating path. Behind the first coating chamber is a temperature regulating device, which is the first temperature regulating device, capable of regulating the temperature of the cable entering the first coating chamber. A second delivery pipe connects to a second nozzle. This second delivery pipe is a conduit for conveying the surface coating powder. Outside the second delivery pipe is a temperature regulating device, which is the second temperature regulating device, capable of regulating the temperature of the surface coating powder inside the second delivery pipe. The first and second temperature regulating devices ensure that the cable temperature is 10-15°C lower than the temperature of the anti-condensation coating.

[0016] Furthermore, the temperature regulating device is connected to the control device.

[0017] Furthermore, a vibration device is also installed on the device frame. The vibration device has a vibration output end, which is connected to a transmission wheel connected to a rotating motor. The transmission wheel has multiple spaced-apart lifting plates on its outer periphery, which press against the coating path in front of the second nozzle.

[0018] The beneficial effects of this invention are:

[0019] Such anti-condensation coatings have the advantage of better anti-condensation effect;

[0020] This method of applying anti-condensation coating also has the advantage of being able to implement the anti-condensation coating mentioned above:

[0021] When S1 spraying is performed, the temperature of the object surface is 10-15°C lower than the temperature of the anti-condensation coating, and it also has the advantages of stronger adhesion between the coating and the object, longer service life, and less damage.

[0022] This anti-condensation coating application device also has the advantage of being able to apply anti-condensation coatings. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example 1

[0027] When an item is coated with ordinary paint, the resulting product has a first coating.

[0028] Such a coating has an anti-condensation effect, meaning that condensation easily adheres to the first coating.

[0029] In one embodiment, the common coating is a water-based coating;

[0030] In one embodiment, the coating comprises paint.

[0031] Example 2

[0032] S1. Apply ordinary paint to an item to form a non-condensing paint layer;

[0033] S2. Spray the surface coating powder onto the non-condensing paint layer and vibrate;

[0034] Example 2-1

[0035] The surface coating powder used includes nanoscale boron fiber powder, nanoscale graphene powder, and nanoscale metal oxide powder, wherein the nanoscale metal oxide powder is at least one of nanoscale cerium oxide powder, nanoscale yttrium oxide powder, and nanoscale neodymium oxide powder.

[0036] The resulting product has a second coating.

[0037] The second coating has a better anti-condensation effect than the first coating, with tests showing a 50-60% reduction in condensation.

[0038] Example 2-2

[0039] Based on Example 2-1, the surface coating powder has been soaked in alkaline solution and then dried.

[0040] The resulting product has a second coating.

[0041] Second, the second coating has a better anti-condensation effect compared to the first coating.

[0042] Secondly, the second coating also has the advantage of maintaining its anti-condensation effect over long-term use;

[0043] In conclusion, the surface coating powder has been soaked in alkaline solution and dried, which gives it the advantage of a stronger bond with the paint.

[0044] Example 2-3

[0045] Based on Example 2-1, the surface coating powder is composed of nano-sized boron fiber powder, nano-sized graphene powder, and nano-sized metal oxide powder in a mass ratio of 1-1.2:1-1.2:1-1.5.

[0046] The resulting product has a second and third coating.

[0047] The second and third coatings have a better anti-condensation effect than the first coating, with tests showing a condensation reduction of 60-70%.

[0048] In summary, the surface coating powder is a good combination of nano-sized boron fiber powder, nano-sized graphene powder, and nano-sized metal oxide powder in a mass ratio of 1-1.2:1-1.2:1-1.5, which is beneficial to improving the anti-condensation effect.

[0049] Examples 2-4

[0050] Based on Example 2-1, the surface coating powder is a nano-scale metal oxide powder including nano-scale cerium oxide powder, nano-scale yttrium oxide powder, and nano-scale neodymium oxide powder; the mass ratio of the nano-scale cerium oxide powder, nano-scale yttrium oxide powder, and nano-scale neodymium oxide powder is 1-1.2:1-1.2:1-1.2.

[0051] The resulting product has a second and fourth coating.

[0052] The second and fourth coatings offer significantly better anti-condensation performance compared to the first coating, achieving the optimal level of anti-condensation. Tests show a 65-72% reduction in condensation.

[0053] In summary: the surface coating powder is a nano-scale metal oxide powder, including nano-scale cerium oxide powder, nano-scale yttrium oxide powder, and nano-scale neodymium oxide powder; the mass ratio of the nano-scale cerium oxide powder, nano-scale yttrium oxide powder, and nano-scale neodymium oxide powder is 1-1.2:1-1.2:1-1.2, which can achieve a better combination and is conducive to improving the anti-condensation effect.

[0054] Examples 2-5

[0055] Based on Example 2-1, the temperature of the object surface is 10-15°C lower than the temperature of the anti-condensation coating.

[0056] The resulting product has a second and fifth coating.

[0057] After testing, the second and fifth coatings showed that they bonded more firmly to the object than the first coating, meaning they were less likely to peel off.

[0058] In summary, a preferred technical solution is to ensure that the surface temperature of the object is 10-15°C lower than the temperature of the anti-condensation coating, resulting in a coating that is less prone to peeling.

[0059] Examples 2-6

[0060] Based on Example 2-1, the surface temperature of the object is 10-15°C, and the temperature of the anti-condensation coating is 20-25°C.

[0061] The resulting product is the second and sixth coatings.

[0062] After testing, the second and sixth coatings showed that they bonded more firmly to the object than the first coating, meaning they were less likely to peel off.

[0063] In summary: the surface temperature of the object is 10-15℃, the temperature of the anti-condensation coating is 20-25℃, and the resulting coating has a stronger bond with the object, meaning the coating is less likely to peel off.

[0064] like Figure 1 As shown, the anti-condensation coating device includes a frame 1, on which are a first roller 11 wound with a raw cable wire and a second roller 12 wound with a coated cable wire. The raw cable wire forms a coating path 2 from the first roller to the second roller. A first coating chamber 3 for spraying the coating body onto the outside of the raw cable wire is installed on the frame. A second coating chamber 4 for spraying powder onto the non-condensing coating layer of the cable is also installed on the frame. The first and second coating chambers have an outlet and an inlet, respectively. The coating path first enters the first coating chamber and then the second coating chamber through the inlet and outlet. The first coating chamber has a first nozzle 31 for spraying the coating body onto the raw cable wire. The first nozzle is connected to a coating body delivery pipe, which is a first delivery pipe 32. The first nozzle faces the coating path inside the first coating chamber. The second coating chamber has a second nozzle 41 for spraying powder onto the non-condensing coating layer of the cable. The second nozzle faces the coating path inside the second coating chamber.

[0065] The above-mentioned anti-condensation coating device can spray coating onto the surface of a cable using a first nozzle, and then immediately follow up by spraying surface coating powder onto the surface of the cable using a second nozzle, thereby producing a product (cable) with a coating surface coated with surface powder, achieving the effect of the present invention.

[0066] Of course, the first nozzle is connected to a device that can spray paint, such as a paint container; the second nozzle is connected to a device that can spray surface powder, such as a surface powder container.

[0067] The cable travels from back to front along the coating path, with direction D in the diagram pointing forward. Behind the first coating chamber is a temperature regulating device, specifically the first temperature regulating device 5. This device regulates the surface temperature of the cable and the cable entering the first coating chamber. A second conveying pipe 42 connects to a second nozzle and carries the surface coating powder. Outside this pipe is a temperature regulating device, specifically the second temperature regulating device 43. This device regulates the temperature of the surface coating powder to meet production process requirements and also regulates the temperature of the powder inside the second conveying pipe. Both the first and second temperature regulating devices ensure that the cable temperature is 10-15°C lower than the temperature of the anti-condensation coating.

[0068] The above settings can make the production process more in line with the requirements of the production technology.

[0069] Furthermore, the temperature regulating device is connected to the control device.

[0070] For example, the control device implemented is a PLC, or an automated control device for the gas source.

[0071] Furthermore, a vibration device 6 is also installed on the device frame. The vibration device has a vibration output end 61, and the vibration output end is connected to a transmission wheel 62 connected to a rotating motor. The outer periphery of the transmission wheel has a plurality of spaced lifting plates 621, which press against the coating path in front of the second nozzle.

[0072] The above-described design of this invention also has the advantage of making it easier for the powder coating on the cable surface to sink into the coating layer under vibration, resulting in a stronger bond between the powder coating and the coating. The multiple spaced-apart lifting plates can transmit the vibration to the cable, and since the cable contacted by the lifting plates is very thin, it will not affect the complete formation of the coating. The direction of arrow F in the figure indicates the direction in which the rotating motor drives the transmission wheel.

[0073] It should be noted that the above embodiments can help in understanding the anti-condensation coating application device, and the above anti-condensation coating application device can also help in understanding the application method of the anti-condensation coating.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
