Description

Technical Field

[0001] The invention relates to the technical field of graphite impregnation, in particular to a method and a device for impregnating graphite with a modified resin. Background Art

[0002] Graphite is an allotrope of carbon, known for its high electrical conductivity and high temperature resistance, and is widely used in many fields. Graphite not only has excellent physical and chemical properties, but also further improves its performance and application range through various processes. From basic science to industrial applications, graphite has demonstrated its irreplaceable position in modern science and technology. The use of synthetic resins such as phenolic resin and epoxy resin to impregnate graphite can significantly improve its mechanical strength and reduce porosity, and enhance acid and alkali resistance. Graphite impregnation is a process that improves its performance by filling synthetic resins or other materials into the pores of graphite. Select suitable graphite materials and pre-treat them, including cleaning, drying and screening. The graphite material is pre-treated and the selected impregnating agent, such as phenolic resin or epoxy resin, is added into the impregnation tank. The impregnation time and temperature are controlled to ensure sufficient penetration. After impregnation, the material is dried and heated to form a solid structure in the pores of the graphite. The curing temperature and pressure need to be strictly controlled to obtain the best effect. The cured material is cut, punched and surface treated to meet specific application requirements, such as mechanical seals, bearings and other high-performance applications. This process not only enhances the strength and wear resistance of the graphite material, but also gives it properties such as impermeability, improved corrosion resistance and thermal stability.

[0003] For example, the patent document with the announcement number CN 115410779 A discloses a graphite electrode impregnation method and a graphite electrode impregnation device, which belongs to the field of graphite electrode impregnation technology, and includes the following steps: S1, placing the graphite electrode into an impregnation container and sealing the impregnation container; S2, evacuating the impregnation container to 0.06-0.09 MPa; S3, injecting an antioxidant protection liquid into the impregnation container until the liquid level of the antioxidant protection liquid is higher than the surface of the graphite electrode; S4, keeping the impregnation for 8-12 minutes; S5, after the impregnation is completed, the impregnation container is depressurized to normal pressure; S6, recovering the antioxidant protection liquid, opening the impregnation container, and taking out the graphite electrode. The present invention transfers the graphite electrode into an impregnation container and evacuates the container to a vacuum level of 0.06-0.09 MPa, thereby discharging gas in the tiny pores of the graphite electrode. Then, an antioxidant protection liquid is injected into the impregnation container and the container is kept for 8-12 minutes for static impregnation, thereby fully impregnating the antioxidant protection liquid into the tiny pores of the graphite electrode, thereby effectively improving the efficiency and quality of the graphite electrode impregnation.

[0004] However, when the existing graphite material is impregnated, the resin material used cannot effectively improve the overall heat resistance of the graphite material. During subsequent use, the graphite material at the resin material impregnation location is easily unable to withstand high temperatures, which limits the use range of the graphite material in a heat-resistant environment. At the same time, when the equipment is performing the impregnation process of the graphite columnar material, it is unable to perform a uniform, all-round vacuum pressure impregnation operation on the graphite column, resulting in uneven and incomplete internal impregnation of the graphite column after impregnation, thereby affecting the heat-resistant use quality of the final graphite as a whole. Moreover, when the equipment is performing graphite impregnation production, it is unable to recycle and reuse the excess resin raw materials impregnated on the graphite column, and is unable to meet daily use needs. Therefore, it is urgent to design a method and device for impregnating graphite with modified resin to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a method and device for impregnating graphite with modified resin, so as to solve the problem in the above background technology that the resin material used in the impregnation of the existing graphite material cannot effectively improve the overall heat resistance of the graphite material. During subsequent use, the graphite material at the resin material impregnation location is easily unable to withstand a high temperature, thereby limiting the use scope of the graphite material in a heat-resistant environment. At the same time, when the equipment is performing the impregnation process of the graphite columnar material, it is impossible to perform a uniform, all-round vacuum pressure impregnation operation on the graphite column, resulting in uneven and incomplete internal impregnation of the graphite column after impregnation, thereby affecting the overall heat-resistant use quality of the final graphite. In addition, when the equipment is performing graphite impregnation production, it is impossible to recycle and reuse the excess resin raw materials impregnated on the graphite column, and the daily use needs cannot be met.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for impregnating graphite with a modified resin:

[0007] S1: First, prepare the modified resin and graphite raw materials. The modified resin is added as an impregnating agent and impregnated into the graphite for filling to improve the performance of the impregnated graphite so that it can achieve good temperature resistance. The graphite is mainly used to prepare graphite chemical equipment. 300° resin (resin that can withstand 300° high temperature-(liquid state, core components: formaldehyde, phenol, catalyst potassium hydroxide) can be used as a graphite impregnating agent on a daily basis. In this process, 300° resin is used as an impregnating agent. Prepare a resin solution containing additives to ensure that the resin used can fully meet the requirements of graphite impregnation and can form a stable structure in the subsequent curing process. Put the treated graphite fiber into the impregnation container, pour the prepared resin solution, and ensure that the graphite fiber is completely covered. The resin is infiltrated into the graphite fiber by vacuum, so that the resin can evenly and fully penetrate into each micropore of the graphite fiber, fill the pores on the surface of the graphite and the internal pores, and then perform heat treatment to cure the resin, thereby forming a composite material with specific properties;

[0008] S2: 300° resin belongs to the category of synthetic resins. Graphite materials impregnated with 300° resin show excellent heat resistance and can be used in environments of 350°C to 400°C, which is the temperature range in which carbon and graphite begin to oxidize. Graphite itself is one of the non-metallic materials with the best thermal conductivity. After being impregnated with 300° resin, its thermal conductivity is retained, making it suitable for use in heat transfer equipment, such as graphite reactors, synthesis furnaces, and heat exchangers. The process of impregnating graphite with modified resin is a complex process involving multiple steps and requiring fine operation. By precisely controlling each link, the performance of graphite composite materials can be significantly improved, expanding their application in high-end fields. With the continuous advancement of materials science and process technology, this field is expected to achieve more innovations and breakthroughs in the future.

Nine graphite columns are grouped as a group, and the positioning and loading operations are carried out inside the impregnation rack. After the loading is completed, the push airbags inside the top adjustment rack and the bottom adjustment rack can be started, and the top movable rack can be connected by connecting the push seat. The limit sliders of the frame and the bottom movable frame are adaptively moved along the limit sliding grooves, so that the top movable frame and the bottom movable frame are adaptively sealed and docked at the upper and lower ends of the impregnation frame. At this time, the vacuum pumps in the centers of the top movable frame and the bottom movable frame are synchronously started, and synchronous and efficient vacuum extraction operations are performed at the upper and lower ends of the impregnation frame, and the vacuum sealing and tightening docking operations at the upper and lower ends of the impregnation frame are performed in coordination with the sealing rings on the first sealing frame and the second sealing frame.
