Description

Technical Field

[0001] This invention relates to the field of material surface modification, and more particularly to a silanization treatment apparatus. Background Technology

[0002] With the rapid development of my country's aerospace industry, the application of low Earth orbit (LEO) spacecraft is increasing, and the demand is becoming more urgent. LEO spacecraft face a complex service environment during operation. The LEO altitude is 200-700 km, and the environment contains high concentrations of highly reactive atomic oxygen. Atomic oxygen can severely corrode polymers such as polyimide films and composite materials such as carbon fiber / resin on the surface of spacecraft in LEO, causing a decrease in the strength of structural materials and a deterioration in the performance of functional materials. The atomic oxygen oxidation and corrosion process can also contaminate sensitive surfaces of the spacecraft, leading to a decline in overall performance and a shortened lifespan, thus affecting the spacecraft's on-orbit service life. Therefore, polymers and composite materials on the surface of spacecraft require atomic oxygen protection.

[0003] Currently, the atomic oxygen protection solutions used domestically and internationally mainly include inorganic silicon oxide and organic silicon protective coatings. These protective coatings have a certain protective effect, but the silicon oxide coating on the substrate surface is prone to cracking due to the abrupt change in the organic / inorganic interface, leading to atomic oxygen erosion and damage to the substrate. In addition, organic silicon coatings are thick, have low protective efficiency, and decompose after exposure, causing pollution and affecting the efficiency of solar cells. The atomic oxygen surface modification technology binds a gradient layer on the surface / subsurface of the substrate, taking into account both substrate compatibility and atomic oxygen protection performance, and is expected to achieve better overall protection performance for low Earth orbit.

[0004] Wet activation silanization is an important surface modification technique to prevent atomic oxygen, comprising three main processes: activation, silanization, and stabilization. However, during the implementation of wet activation silanization, especially when processing large samples, problems may arise due to the fragility of the activated surface layer, such as detachment, unevenness, and insufficient depth. On one hand, conventional vibration or shaking methods in the silanization apparatus can easily lead to the detachment of the activated surface layer during silanization; on the other hand, using a static solution in the silanization process can result in uneven silanization. To mitigate these issues, a method of sample statication combined with conventional solution convection can lead to insufficient silanization layer depth. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a silanization treatment apparatus that solves the problem of poor silanization effect in the samples processed by existing silanization treatment apparatuses.

[0006] To achieve the above objectives, the present invention provides a silanization treatment apparatus, comprising:

[0007] The shell has a reaction tank inside, which is used to place the sample to be silanized and the silane reagent. The shell also has several heating plates, which are distributed on both sides outside the reaction tank.

[0008] At least two liquid guide tubes are provided, each located on one side of the sample to be silanized within the reaction tank. Each liquid guide tube has several liquid guide holes and is connected by a flexible tube. A power pump is also connected to the flexible tube. The liquid guide tubes, the flexible tube, and the reaction tank form a closed loop, allowing the silane reagent to circulate within the closed loop at a predetermined flow rate under the drive of the power pump.

[0009] By setting liquid guiding pipes with liquid guiding holes on both sides of the sample to be silanized, and simultaneously allowing the silane reagent to flow in the reaction tank at a predetermined flow rate under the drive of a power pump, the setting of multiple liquid guiding holes diverts the silane reagent flowing through the liquid guiding pipes multiple times, effectively reducing the pressure of the silane reagent and thus forming a microflow. This allows the two sides of the sample to be silanized to fully contact and react with the silane reagent, effectively increasing the depth of the silanized layer on the sample surface and thus effectively extending the subsequent service life of the sample product.

[0010] In some embodiments, the reaction tank is a T-shaped reaction tank, which includes a horizontal groove and a vertical groove that is perpendicularly connected to the horizontal groove. The vertical groove is used to place the sample to be silanized. The connection between the horizontal groove and the vertical groove is chamfered.

[0011] The T-shaped reaction vessel design not only effectively saves the amount of silane reagent used in the reaction vessel, but also effectively solves the problem of silane reagent overflow caused by volume expansion after heating.

[0012] In some embodiments, the liquid guiding tubes are all U-shaped liquid guiding tubes, and there are two U-shaped liquid guiding tubes. The U-shaped liquid guiding tubes are respectively disposed at both ends of the sample to be silanized, corresponding to the flow direction of the silane reagent. Each U-shaped liquid guiding tube includes two parallel pipes, and the two parallel pipes are respectively close to the tank walls on both sides of the longitudinal groove. The sample to be silanized is placed between the two pipes.

[0013] The U-shaped liquid guide tube is designed so that both sides of the sample to be silanized have liquid guide holes corresponding to the flow direction of the silane reagent. This ensures that both sides of the sample can be in contact with the silane reagent at the same flow rate, effectively ensuring that the silanization layer depth on both sides of the sample remains consistent. The liquid guide holes on the U-shaped liquid guide tube are oriented towards or away from the flow direction of the silane reagent, ensuring the consistency of the flow direction and the uniformity of the flow rate of the silane reagent flowing out through the liquid guide holes. In addition, the U-shaped liquid guide tube is set at both ends of the sample to be silanized in the direction of the silane reagent flow, so that the flow range of the silane reagent through the liquid guide holes covers both sides of the sample to be silanized, thereby making the silanization reaction uniform on both sides of the sample to be silanized.

[0014] In some embodiments, both ends of the U-shaped liquid guide tube are provided with flow guide sleeves, and the two corresponding flow guide sleeves are connected to the flexible tube through a three-way conduit;

[0015] Both ends of the U-shaped liquid guide tube include a connecting ring, and one side of the connecting ring is connected to the U-shaped liquid guide tube. The guide sleeve includes a sleeve and a fixing nut. One end of the sleeve is connected to the three-way conduit, and the other end of the sleeve is fitted with the fixing nut. The end of the sleeve away from the three-way conduit is provided with a connecting groove corresponding to the connecting ring, and the connecting groove is provided with several small holes.

[0016] The flow guide sleeve divides the pressure of the silane reagent flowing into the liquid guide tube to form a mixed microflow, thereby effectively ensuring the uniformity of pressure at both ends of the U-shaped liquid guide tube and the uniformity of pressure in the flow guide hole, so that the silane reagent can flow parallel to the reaction tank through the liquid guide hole.

[0017] In some embodiments, the heating plate is disposed on a side wall of the housing that is parallel to the flow direction of the silane reagent, a gap is left between the heating plate and the longitudinal groove, and heat insulation cotton is also disposed between the heating plates, the heat insulation cotton covering the side wall of the housing.

[0018] The heating plate radiates heat from the longitudinal groove, heating the sidewalls of the groove and conducting heat to the silane reagent in the reaction tank. This makes the heating of the silane reagent more uniform and safer, effectively avoiding the problem of local overheating of the silane reagent caused by direct heating, which could lead to the temperature of the silane reagent exceeding its flash point and causing an explosion. In addition, the use of insulation cotton enhances the heat preservation performance of the silanization treatment device.

[0019] In some embodiments, the hose is further provided with a pipe electric heater and a pressure relief valve. The pipe electric heater is used to heat the silane reagent flowing through the hose, and the pressure relief valve is used to reduce the pressure inside the hose.

[0020] The silane reagent flowing out of the reaction tank and then through the hose is heated by a pipeline electric heater, so that the temperature of the silane reagent flowing out of the reaction tank and then through the hose is basically the same as the temperature of the silane reagent inside the reaction tank.

[0021] In some embodiments, the opening of the reaction tank is provided with a sealing cover, which is rotatably connected to one side of the opening;

[0022] A cylinder device is fixedly installed on one side of the housing connected to the sealing cover. The output end of the cylinder device is connected to the side of the sealing cover away from the reaction tank, so that the sealing cover can rotate under the drive of the cylinder device.

[0023] In some embodiments, an air knife device is provided on the side of the opening away from the connection between the sealing cap and the opening, and the air knife device faces the side of the connection structure between the sealing cap and the opening to form an inert gas air curtain to protect the silane reagent.

[0024] By installing an air knife device, the silane reagent inside the reaction tank can be protected from the influence of outside air even when the sealing cover is opened during the stage of heating the silane reagent to a high temperature, thus ensuring the quality of the silane reagent and providing a guarantee for the silanization process.

[0025] In some embodiments, the housing further includes a liquid level observation port, a temperature measuring port, and a drain port. The liquid level observation port is located on the side wall of the housing near the three-way conduit, the temperature measuring port is located on the side wall of the housing near the heating plate, and the drain port is located on the side wall of the housing corresponding to the bottom of the longitudinal groove.

[0026] In some embodiments, the housing further includes a plurality of anti-drip grooves, which are disposed below the connection structure between the sealing cap and the opening.

[0027] Anti-drip tanks are used to collect waste liquid that evaporates from the reaction tank and solidifies on the sealed cover, and the waste liquid is recycled periodically to protect the environment.

[0028] The silanization treatment apparatus provided by the present invention can bring at least one of the following beneficial effects:

[0029] 1. This invention places the sample to be silanized in a reaction tank filled with an appropriate amount of silane reagent. Simultaneously, the silane reagent, driven by a power pump, flows convectively across both sides of the sample at a predetermined flow rate. The design of several guide holes diverts the silane reagent flowing through the guide tube multiple times, effectively reducing the pressure of the silane reagent and forming a microflow. This allows the sample to fully contact and react with the flowing silane reagent, achieving uniform silanization on the sample surface. This effectively avoids insufficient silanization depth, which could lead to the silanization layer peeling off, thus improving the yield of silanized products and providing effective assurance for the subsequent use of silanized products.

[0030] 2. The U-shaped liquid guide tube in this invention provides liquid guide holes on both sides of the sample to be silanized, allowing both sides of the sample to come into contact with silane reagent at the same flow rate. This avoids concentration differences of silane reagent on the sample surface caused by the reaction, effectively ensuring that the silanization layer depth on both sides of the sample remains consistent. The liquid guide holes on the U-shaped liquid guide tube face or away from the direction of silane reagent flow, ensuring consistent flow direction and uniform flow rate of the silane reagent flowing out through the liquid guide holes. In addition, the guide sleeve forms a mixed microflow of silane reagent flowing into the liquid guide tube, effectively ensuring the uniformity of pressure at both ends of the U-shaped liquid guide tube and the uniformity of pressure in the guide holes. This allows the silane reagent to flow parallel to the reaction tank through the liquid guide holes, further optimizing the stability of the silane reagent flow and enhancing the silanization effect of the sample to be silanized.

Detailed Implementation

[0040] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0041] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0042] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0043] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] In one embodiment, refer to the appendix to the specification. Figures 1 to 6As shown, the silanization treatment apparatus provided by the present invention includes a housing 10 and at least two liquid guide pipes. The housing 10 has a reaction tank 20 inside, which is used to place the sample to be silanized and the silane reagent, so that the sample to be silanized is immersed in the silane reagent. The housing 10 is also provided with a plurality of heating plates 12, which are distributed on both sides outside the reaction tank 20. The liquid guide pipes are all arranged inside the reaction tank 20 on both sides corresponding to the sample to be silanized. The liquid guide pipes are provided with a plurality of liquid guide holes 31. The liquid guide pipes are connected by hoses 40, and the hoses 40 are also connected to a power pump 60. The plurality of liquid guide pipes, hoses 40 and reaction tank 20 form a closed loop pipeline, so that the silane reagent can circulate in the closed loop pipeline at a predetermined flow rate under the drive of the power pump 60.

[0046] Specifically, the flow rate of the silane reagent is adjusted by controlling the power pump 60 so that the silane reagent can flow at a predetermined flow rate, avoiding the sample to be silanized from being washed away and damaged due to excessive flow rate. Then, through the guiding effect of the liquid guide hole 31, the flow direction of the silane reagent in the reaction tank 20 is made uniform and singular. It should be noted that the material of the hose is generally stainless steel.

[0047] In one embodiment, refer to the appendix to the specification. Figure 2 As shown, the reaction tank 20 is a T-shaped reaction tank 20. The T-shaped reaction tank 20 includes a horizontal groove 21 and a vertical groove 23 that is perpendicularly connected to the horizontal groove 21. The vertical groove 23 is used to place the sample to be silanized. The connection between the horizontal groove 21 and the vertical groove 23 is provided with a chamfer.

[0048] Specifically, the view of the reaction tank 20 from the direction of silane reagent flow is a "T" structure. The longitudinal groove 23 is connected to the middle position of the transverse groove 21. When using the silanization treatment device, the sample to be silanized is placed in the longitudinal groove 23. This not only helps to reduce the amount of silane reagent used to effectively reduce costs, but also effectively avoids the situation where the silane reagent expands and overflows after heating. In addition, the connection between the transverse groove 21 and the longitudinal groove 23 is provided with chamfers to facilitate the placement of the sample to be silanized in the longitudinal groove 23.

[0049] In one embodiment, based on the previous embodiment, refer to the appendix to the specification. Figure 3 As shown, the liquid guiding tubes are all U-shaped liquid guiding tubes 30, and there are two U-shaped liquid guiding tubes 30. The U-shaped liquid guiding tubes 30 are respectively set at both ends of the flow direction of the silane reagent corresponding to the sample to be silanized. The U-shaped liquid guiding tube 30 includes two parallel pipes, and the two parallel pipes are respectively close to the tank walls on both sides of the longitudinal groove 23. The sample to be silanized is placed between the two pipes.

[0050] Specifically, one U-shaped liquid guide tube 30 serves as the liquid inlet tube, and the other U-shaped liquid guide tube 30 serves as the liquid outlet tube. The U-shaped liquid guide tube 30 is formed by bending a metal tube with high thermal conductivity. The metal tube can be made of any one of copper, aluminum, and titanium, depending on the actual needs. A guide hole is opened at fixed intervals. The guide hole can be a small circular hole, and the hole shape can also be a square, hexagon, or other symmetrical regular shape, depending on the turbulence characteristics of the actual liquid.

[0051] In one embodiment, refer to the appendix to the specification. Figure 3 and Figure 6 As shown, both ends of the U-shaped liquid guide tube 30 are provided with a flow guide sleeve 22. The two corresponding flow guide sleeves 22 are connected to the hose 40 through a three-way conduit 41. Both ends of the U-shaped liquid guide tube 30 include a connecting ring 32. One side of the connecting ring 32 is connected to the U-shaped liquid guide tube 30. The flow guide sleeve 22 includes a sleeve and a fixing nut. One end of the sleeve is connected to the three-way conduit 41, and the other end of the sleeve is fitted with a fixing nut. The end of the sleeve away from the three-way conduit 41 is provided with a connecting groove corresponding to the connecting ring 32. Several small holes are provided on the connecting groove.

[0052] Specifically, the U-shaped liquid guide tube 30, which serves as the liquid inlet pipe, allows the silane reagent flowing through the guide tube 22 to be diverted through several small holes, thus forming multiple mixed microflows. This effectively ensures the uniformity of pressure at both ends of the U-shaped liquid guide tube 30 and the uniformity of pressure in the guide holes, allowing the silane reagent to flow parallel to the reaction tank 20 through the guide holes 31. In addition, the detachable nature of the guide sleeve 22 makes it easy to replace the U-shaped liquid guide tube 30.

[0053] In one embodiment, refer to the appendix to the specification. Figure 3 and Figure 5 As shown, the heating plate 12 is disposed on the side wall of the housing 10, which is parallel to the flow direction of the silane reagent. A gap is left between the heating plate 12 and the longitudinal groove 23. Insulation cotton 11 is also disposed between the heating plates 12, and the insulation cotton 11 covers the side wall of the housing 10.

[0054] Specifically, the heating plates 12 can be divided into 8 groups. The heating plates 12 at corresponding positions on both sides of the reaction tank 20 constitute one group. Each group of heating plates 12 consists of 2 plates. Each group of heating plates 12 is controlled by a temperature controller to more accurately control the heating uniformity of the heating plates 12. The heating plates 12 are specifically infrared heating plates 12, or they can be ceramic heating plates, depending on the heating characteristics of the material to be silanized. The insulation cotton 11 can be made of alumina fiber cotton.

[0055] In one embodiment, refer to the appendix to the specification. Figure 4As shown, the hose 40 is also equipped with a pipe electric heater 50 and a pressure relief valve 100. The pipe electric heater 50 is used to heat the silane reagent flowing through the hose 40, and the pressure relief valve 100 is used to reduce the pressure inside the hose 40.

[0056] Specifically, when the silane reagent circulates, it can pass through the pipeline electric heater 50, the power pump 60, and the pressure relief valve 100 in sequence. The pipeline electric heater 50, the power pump 60, and the pressure relief valve 100 are all installed on the back of the housing 10 near the bottom. The pipeline electric heater 50 is equipped with a thermometer at both the inlet and outlet, so that the pipeline electric heater 50 can be adjusted by observing the thermometer, thereby ensuring that the temperature of the silane reagent that circulates back into the reaction tank 20 is basically the same as the temperature of the silane reagent in the reaction tank 20.

[0057] In one embodiment, based on the above embodiments, refer to the appendix to the specification. Figure 2 As shown, the opening of the reaction tank 20 is provided with a sealing cover 80. The sealing cover 80 is rotatably connected to one side of the opening. A cylinder device 70 is fixedly provided on the side of the housing 10 connected to the sealing cover 80. The output end of the cylinder device 70 is connected to the side of the sealing cover 80 away from the reaction tank 20, so that the sealing cover 80 can rotate under the drive of the cylinder device 70, which facilitates the opening and closing of the sealing cover 80.

[0058] It should be noted that a sealant 82 is provided around the opening of the sealing cover 80 to ensure the sealing of the reaction tank 20 after the sealing cover 80 is closed.

[0059] In one embodiment, based on the above embodiments, refer to the appendix to the specification. Figure 2 As shown, an air knife device 81 is provided on the side of the opening away from the sealing cover 80 and connected to the opening. The air knife device 81 faces the side of the connection structure between the sealing cover 80 and the opening to form an inert gas air curtain to protect the silane reagent.

[0060] Specifically, the air knife device 81 and the sealing cover 80 are linked and controlled. When the sealing cover 80 is opened during the stage of heating the silane reagent to a high temperature, the contact switch of the air knife device 81 is triggered, so that the air knife device 81 is turned on. This effectively prevents the silane reagent in the reaction tank 20 from being affected by the outside air, thereby affecting the reaction quality of the final silanization of the sample to be silanized.

[0061] In one embodiment, refer to the appendix to the specification. Figure 1 and Figure 3 As shown, the housing 10 also includes a liquid level observation port, a temperature measuring port 13, and a drain port 90. The liquid level observation port is located on the side wall of the housing 10 near the three-way conduit 41, the temperature measuring port 13 is located on the side wall of the housing 10 near the heating plate 12, and the drain port 90 is located on the side wall of the bottom of the longitudinal groove 23 of the housing 10.

[0062] Specifically, the liquid level observation port is used to read the liquid level changes in the reaction tank 20 to record the usage and consumption of silane reagent. Alternatively, the volume of silane reagent in the reaction tank 20 can be observed by setting up a liquid level gauge or other device, so as to replenish the silane reagent in a timely manner to ensure that the silane treatment of the sample to be silanized can continue. The drain port 90 is used to replenish and discharge silane reagent.

[0063] In one embodiment, refer to the appendix to the specification. Figure 3 As shown, the housing 10 also includes several anti-drip tanks, which are located below the connection structure between the sealing cover 80 and the opening. The anti-drip tanks are used to collect waste liquid that evaporates from the reaction tank 20 and solidifies on the sealing cover 80, and to periodically recycle the waste liquid to protect the environment.

[0064] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
