Description

Technical Field

[0001] This invention relates to the field of glass fiber technology, and in particular to a device and method for removing adhesive layers from fiber surfaces. Background Technology

[0002] Currently, when using fiberglass cloth, we use it as a substrate and perform CVD (chemical vapor deposition) growth on its surface to impart excellent electrical and thermal conductivity. However, when removing adhesive from fiberglass cloth, it is found that uniform removal is difficult, making it hard to achieve a clean surface. Summary of the Invention

[0003] This invention provides a device and method for removing adhesive layers from the surface of fibers, so as to ensure more uniform removal of adhesive layers from the surface of the original fiber fabric, resulting in a cleaner and more pollution-free fiber fabric after adhesive removal.

[0004] In a first aspect, embodiments of the present invention provide a device for removing adhesive layers from fiber surfaces, comprising:

[0005] The first roll is used to hold the original fiber fabric for which the surface adhesive layer is to be removed;

[0006] A second roll is used to roll up the fibrous cloth after the surface adhesive layer has been removed;

[0007] A heating furnace body, located between the first roll and the second roll, is used to heat the fiber fabric.

[0008] The device for promoting the decomposition of the adhesive layer is connected to the heating furnace body through a first valve and is used to provide a first substance, which can accelerate the removal of the adhesive layer on the surface of the fiber fabric.

[0009] In a second aspect, embodiments of the present invention provide a method for removing an adhesive layer from a fiber surface, executed by the fiber surface adhesive layer removal apparatus described in the first aspect, the method comprising:

[0010] Provide the original fiber fabric from which the adhesive layer on the surface to be removed;

[0011] The temperature of the heating furnace body is set to a first temperature, and the fiber fabric is heated for treatment.

[0012] The first valve is opened, allowing the adhesive layer decomposition promotion device to supply a first substance into the heating furnace, which can accelerate the removal of the adhesive layer on the surface of the fiber fabric.

[0013] The solution provided by this invention involves placing the heating furnace body between the first and second rollers, so that the fiber fabric is laid flat when passing through the heating furnace body, which facilitates uniform degumming of the fiber fabric. The device that promotes the decomposition of the adhesive layer is connected to the heating furnace body through a first valve. During the heating process of the fiber fabric in the heating furnace body, the first valve is opened, allowing the first substance provided by the device that promotes the decomposition of the adhesive layer to enter the heating furnace body. This accelerates the removal of the adhesive layer on the surface of the fiber fabric, improves the degumming efficiency, and makes the removal of the adhesive layer on the surface of the fiber fabric more uniform and clean without damaging the fiber fabric. This ensures that the fiber fabric finally rolled up by the second roller is cleaner and free of contamination.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the basic concepts disclosed and indicated in the embodiments of this invention, all other embodiments obtained by those skilled in the art are within the scope of protection of this invention.

[0024] As described in the background art, glass fiber is widely used as a reinforcing material due to its excellent tensile strength, elastic modulus, impact resistance, and fatigue resistance, achieving a market share of over 90%. However, due to its high hardness and brittleness, glass fiber often requires a sizing agent to be applied to its surface during production. This coating imparts flexibility for winding and large-scale production. Before use, the adhesive layer needs to be removed from the fiber cloth surface, and the exposed glass fibers need to be treated to better utilize their properties. The adhesive layer on the glass fiber surface is typically an epoxy resin film-forming agent, lubricant, or silane coupling agent. However, current techniques for removing the adhesive layer from the glass fiber surface usually involve organic solvents or heating, which is time-consuming and results in uneven removal. Furthermore, organic solvents can react with components on the fiber surface, affecting fiber quality.

[0025] Based on this, the inventors conducted in-depth research and found that the main factors affecting the cleanliness of fiber cloth degumming include the heating furnace temperature, the contact area between the fiber cloth and air, the heating time of the fiber cloth, and the pretreatment method. Among these, the pretreatment methods can include static pretreatment, dynamic roll-type pretreatment, and dynamic roll-to-roll pretreatment. Static pretreatment involves rolling the fiber cloth into a roll and then degumming it. Its disadvantages are uneven degumming, residual adhesive easily remaining in the core area, and a relatively small amount of fiber cloth processed. Dynamic roll-type pretreatment is an improvement on static pretreatment. Because it involves dynamic movement, it avoids the problem of uneven degumming caused by uneven heating of the outer layer. However, it still involves rolling the cloth into a roll, so residual adhesive will still remain in the core area. Dynamic roll-to-roll pretreatment combines dynamic methods with a single-layer flat laying method of the fiber cloth, theoretically ensuring all-round uniformity and cleanliness of fiber cloth degumming, and is the optimal degumming method discovered so far. However, the adhesive layer on the surface of the fiber cloth is also affected by a variety of other factors, which makes the removal of the adhesive layer on the surface of the fiber cloth time-consuming and uneven, and makes it impossible to obtain a cleaner and more pollution-free fiber cloth.

[0026] Based on the above-mentioned technical problems, embodiments of the present invention provide a device for removing adhesive layers from the surface of fibers. The device includes: a first roller for placing the original fiber fabric with the adhesive layer to be removed; a second roller for rolling up the fiber fabric with the adhesive layer removed; a heating furnace body located between the first roller and the second roller for heating the original fiber fabric; and an adhesive layer decomposition promoting device connected to the heating furnace body through a first valve for providing a first substance, which can accelerate the removal of the adhesive layer on the surface of the original fiber fabric.

[0027] By adopting the above technical solution, the heating furnace body is placed between the first and second rolls, so that the fiber cloth is laid flat when passing through the heating furnace body, which is conducive to uniform degumming of the fiber cloth. The device for promoting the decomposition of the adhesive layer is connected to the heating furnace body through the first valve. During the heating process of the fiber cloth in the heating furnace body, the first valve is opened, so that the first substance provided by the device for promoting the decomposition of the adhesive layer can enter the heating furnace body, thereby accelerating the removal of the adhesive layer on the surface of the fiber cloth, improving the degumming efficiency, and making the removal of the adhesive layer on the surface of the fiber cloth more uniform and clean, without damaging the fiber cloth, ensuring that the fiber cloth finally rolled up by the second roll is cleaner and free of pollution.

[0028] The above is the core idea of ​​this application. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] Figure 1 This is a schematic diagram of a fiber surface adhesive layer removal device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the device includes: a first roller 10 for placing the fiber cloth 11 to which the surface adhesive layer is to be removed; a second roller 20 for winding up the fiber cloth with the surface adhesive layer removed; a heating furnace 30 located between the first roller 10 and the second roller 20 for heating the fiber cloth 11; and an adhesive layer decomposition promoting device 40, which is connected to the heating furnace 30 through a first valve 50 for providing a first substance that can accelerate the removal of the adhesive layer on the surface of the fiber cloth 11.

[0030] The fiber base fabric 11 can be glass fiber, but is not limited to it. Glass fiber can be divided into quartz fiber, high silica fiber and ordinary fiber, depending on the silica content. This embodiment of the invention does not make specific limitations on this and can be set according to actual needs.

[0031] It is understood that the first roller 10 is the unwinding roller, and the second roller 20 is the take-up roller. The radius of the first roller 10 and the radius of the second roller 20 can be the same or different. This embodiment of the invention does not impose specific limitations on this and can be set according to actual needs. The first roller 10 and the second roller 20 can move synchronously at a uniform speed, so that the fiber fabric 11 moves from the first roller 10 to the second roller 20.

[0032] Optionally, the first valve 50 may include, but is not limited to, a solenoid valve.

[0033] Specifically, the heating furnace body 30 is positioned between the first roll 10 and the second roll 20, so that the fiber fabric 11 is laid flat when passing through the heating furnace body 30. The heating temperature of the heating furnace body 30 can be set according to the specific material of the fiber fabric 11 and the speed at which the fiber fabric 11 moves. For example, the heating temperature can be between 200℃ and 700℃, including 200℃ or 700℃. This embodiment of the invention does not specifically limit this and can be set according to actual needs. At the same time, during the heating process of the fiber fabric 11 by the heating furnace body 30, the first valve 50 is opened, so that the pipe connecting the adhesive layer decomposition device 40 and the heating furnace body 30 is open. At this time, the first substance provided by the adhesive layer decomposition device 40 can enter the heating furnace body 30, thereby accelerating the removal of the adhesive layer on the surface of the fiber fabric 11, improving the adhesive removal efficiency, and making the adhesive layer on the surface of the fiber fabric 11 more evenly and cleanly removed without damaging the fiber fabric 11, ensuring that the fiber fabric (also known as the fiber substrate) finally rolled up by the second roll 20 is cleaner and free of contamination.

[0034] It should be noted that the first substance can be introduced through the gas in the gel decomposition device 40. The specific gas can be set according to actual needs, including but not limited to oxygen, carbon dioxide or nitrogen.

[0035] Optionally, the first substance includes at least water. The inventors have discovered that by introducing water into the heating furnace 30, the adhesive layer on the surface of the fiber fabric 11 can be quickly removed, providing a uniform, clean and pollution-free fiber substrate for subsequent processing.

[0036] Optional, Figure 2 This is a schematic diagram of another fiber surface adhesive layer removal device provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the device also includes a temperature controller 60; the heating furnace body 30 includes an upper furnace body 31 and a lower furnace body 32; the temperature controller 60 is electrically connected to the upper furnace body 31 and the lower furnace body 32 respectively, and is used to control the temperature of the upper furnace body 31 and the lower furnace body 32 respectively.

[0037] Specifically, the temperature controller 60 can arbitrarily adjust the temperature of the upper furnace body 31 and the lower furnace body 32 according to user parameter settings or internal system control. The temperatures of the upper furnace body 31 and the lower furnace body 32 can be the same or different, and can be set according to actual needs. This embodiment of the invention does not make specific limitations in this regard.

[0038] Optional, Figure 3 This is a schematic diagram of the structure of another fiber surface adhesive layer removal device provided in an embodiment of the present invention, combined with... Figure 2 and Figure 3 As shown, it also includes a roller driver 70, which is electrically connected to the first roller 10 and the second roller 20 respectively, and is used to drive the first roller 10 and the second roller 20 to rotate at a preset speed.

[0039] Specifically, the preset speed can be any value, for example, the preset speed range is 50mm / min to 250mm / min, which can be set according to actual needs. Furthermore, the roller driver 70 can also be connected to… Figure 2 The temperature controller 60 shown in the figure Figure 3 (Not shown in the image) Linkage control, that is, the preset speed can be automatically adjusted according to the real-time temperature of the heating furnace 30. The higher the temperature of the heating furnace 30, the greater the preset speed of the first roller 10 and the second roller 20, which improves the intelligence level of the entire removal device. In addition, while ensuring that the fiber cloth 11 removes the surface adhesive layer quickly and evenly, it avoids the fiber substrate being heated to too high a temperature, which is conducive to rapid cooling and improves the efficiency of the entire process.

[0040] Understandably, since the first substance needs to include water in order to quickly remove the adhesive layer on the surface of the fiber fabric 11, the adhesive layer decomposition device 40 can be any device capable of providing water.

[0041] In an optional embodiment, Figure 4 This is a schematic diagram of the structure of another fiber surface adhesive layer removal device provided in an embodiment of the present invention, as shown below. Figure 4 As shown, the device 40 for promoting the decomposition of the adhesive layer includes a gas storage bottle 41 and a liquid storage bottle 42. The output pipe of the gas storage bottle 41 extends to the bottom of the liquid storage bottle 42, and the output pipe of the liquid storage bottle 42 is connected to the heating furnace body 30. The gas storage bottle 41 contains a first gas, and the liquid storage bottle 42 contains deionized water.

[0042] Specifically, there is a certain pressure difference between the inside and outside of the gas storage cylinder 41. When the first valve 50 is opened, the first gas in the gas storage cylinder 41 can be introduced into the liquid storage cylinder 42 under the action of pressure, so that some of the deionized water in the liquid storage cylinder 42 can enter the heating furnace body 30, thereby accelerating the removal of the adhesive layer on the surface of the fiber cloth 11.

[0043] The first gas can be oxygen, carbon dioxide, or nitrogen, etc., and can be set according to actual needs. Preferably, the first gas is oxygen, which can further accelerate the removal of the adhesive layer on the surface of the fiber fabric 11, making the removal of the adhesive layer on the surface of the fiber fabric 11 more uniform and clean.

[0044] In another alternative embodiment, Figure 5 This is a schematic diagram of the structure of another fiber surface adhesive layer removal device provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the device 40 for promoting the decomposition of the adhesive layer includes a first reaction vessel 43, which contains a manganese dioxide and hydrogen peroxide solution.

[0045] The reaction vessel 43 can be a glass container, but is not limited to it.

[0046] Specifically, hydrogen peroxide solution, commonly known as hydrogen peroxide, can be pure hydrogen peroxide solution or a solution miscible with water in any proportion in this embodiment; no specific limitation is made here. Under the catalytic action of manganese dioxide, the hydrogen peroxide solution can decompose into water and oxygen. When the first valve 50 is open, the oxygen flow can introduce some water into the heating furnace 30, thereby accelerating the removal of the adhesive layer on the surface of the fiber fabric 11, resulting in a more uniform removal of the adhesive layer and achieving a clean and pollution-free finish.

[0047] It should be noted that the specific substances contained in the first reaction container 43 include, but are not limited to, manganese dioxide and hydrogen peroxide solution. They can be any chemical substance that can produce non-toxic gas and water through chemical reaction. The specific substances can be set according to the actual situation and are not limited to these.

[0048] In yet another alternative embodiment, Figure 6 This is a schematic diagram of the structure of another fiber surface adhesive layer removal device provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the device 40 for promoting the decomposition of the adhesive layer includes a second reaction container 44 and a heating module 45; the second reaction container 44 contains first solid particles; the heating module 45 is used to heat the second reaction container 44 so that the first solid particles decompose to produce water.

[0049] The second reaction vessel 44 can be made of a material with good thermal conductivity and is not easily reacted with chemical substances.

[0050] Specifically, the heating module 45 can heat the second reaction container 44 so that the first solid particles in the second reaction container 44 can decompose into gas and water when heated. Depending on the specific type of the first solid particles, the gas produced by its thermal decomposition will also be different. Optionally, the first solid particles can be basic copper carbonate, ammonium bicarbonate, or sodium bicarbonate, etc. In this way, when the first valve 50 is opened, the gas (e.g., carbon dioxide) produced by the heating and decomposition of the first solid particles can introduce some water into the heating furnace body 30, thereby accelerating the removal of the adhesive layer on the surface of the fiber cloth 11, making the removal of the adhesive layer on the surface of the fiber cloth 11 more uniform and achieving cleanliness and no pollution.

[0051] Optional, continue to refer to Figure 6 As shown, the heating module 45 includes a water bath heating pot, and the second reaction vessel 44 is placed inside the water bath heating pot.

[0052] Specifically, the heating module 45 can be a water bath heating pot, which contains a liquid such as water. In addition, a heater can also be installed inside the water bath heating pot. Figure 6 (Not shown in the image) to heat the liquid in the water bath heating pot. Since the second reaction vessel 44 has a certain thermal conductivity, heat is transferred to the second reaction vessel 44, so that the first solid particles in the second reaction vessel 44 can decompose into gas and water when heated. Then, the water is introduced into the heating furnace body 30 through gas flow to accelerate the removal of the adhesive layer on the surface of the fiber cloth 11, so that the adhesive layer on the surface of the fiber cloth 11 is removed more evenly and achieves cleanliness and no pollution.

[0053] Alternatively, the water bath heating pot can be an ultrasonic cleaner. While heating the liquid in the water bath heating pot, ultrasonic vibration is performed for a period of time, so that the liquid can heat the second reaction container 44 and make the second reaction container 44 vibrate, thereby accelerating the decomposition rate of the first solid particles in the second reaction container 44. This allows water to be quickly and fully introduced into the heating furnace body 30 to accelerate the removal of the adhesive layer on the surface of the fiber cloth 11, making the removal of the adhesive layer on the surface of the fiber cloth 11 more uniform and achieving a clean and pollution-free result.

[0054] Optional, continue to refer to Figures 1 to 6 As shown, the interface between the adhesive layer decomposition device 40 and the heating furnace body 30 is located on the side of the heating furnace body 30 near the first roller 10.

[0055] Specifically, the fiber cloth 11 moves from the first roller 10 to the second roller 20. By setting the communication interface between the adhesive layer decomposition device 40 and the heating furnace body 30 on the side of the heating furnace body 30 close to the first roller 10, the fiber cloth 11 with the surface adhesive layer not removed can make full contact with the first substance provided by the adhesive layer decomposition device 40 as soon as it moves into the heating furnace body 30, thereby accelerating the removal of the adhesive layer on the surface of the fiber cloth 11, making the removal of the surface adhesive layer of the fiber cloth 11 more uniform and achieving cleanliness and no pollution.

[0056] Based on the same inventive concept, embodiments of the present invention also provide a method for removing the adhesive layer on the fiber surface, which is executed by the fiber surface adhesive layer removal device provided in any of the above embodiments. Figure 7 A flowchart of a method for removing adhesive layers from fiber surfaces provided in an embodiment of the present invention, in conjunction with reference to [reference needed]. Figure 1 and Figure 7 As shown, the method for removing the adhesive layer on the fiber surface includes:

[0057] S101, Provide the fiber fabric from which the surface adhesive layer is to be removed.

[0058] S102. Set the temperature of the heating furnace body to the first temperature and heat the fiber fabric.

[0059] The first temperature can be any value and can be set according to actual needs. For example, the range of the first temperature is 200℃~700℃.

[0060] S103. Open the first valve to allow the adhesive layer decomposition device to supply the first substance to the heating furnace. The first substance can accelerate the removal of the adhesive layer on the surface of the fiber cloth.

[0061] Optionally, the first substance includes water, which can quickly remove the adhesive layer on the surface of the fiber fabric 11 and promote the decomposition of the adhesive layer. The device can be any device capable of providing water, as can be referenced. Figures 4 to 6 However, it is not limited to this.

[0062] In this embodiment of the invention, by providing a fiber fabric with a surface adhesive layer to be removed, and setting the temperature of the heating furnace to a first temperature, the fiber fabric is heated to remove the adhesive layer on the surface of the fiber fabric through high-temperature heating. The method is relatively simple. During the heating process of the fiber fabric in the heating furnace, a first valve is opened to allow the adhesive layer decomposition device to provide a first substance into the heating furnace to accelerate the removal of the adhesive layer on the surface of the fiber fabric. This not only improves the adhesive removal efficiency but also makes the adhesive layer on the surface of the fiber fabric removed more evenly and cleanly, without damaging the fiber substrate, ensuring that the final de-adhesive fiber fabric is cleaner and free of pollution.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention.
