Description

Technical Field

[0001] This utility model relates to the field of basalt fiber production and manufacturing, and specifically to a basalt fiber impregnation box. Background Technology

[0002] As a high-performance inorganic fiber material, the interfacial wetting effect of basalt fiber directly affects the mechanical properties of composite products. Current industrial production commonly employs vertical impregnation tanks for surface treatment. This equipment consists of a 304 stainless steel tank, guide rollers, and a constant-temperature circulation system. In practice, basalt fiber bundles are vertically introduced into the tank containing an epoxy resin / aminosilane composite impregnating agent via guide rollers at a linear velocity of 6-8 m / min, with the impregnation time controlled within the range of 45-60 seconds. However, scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) analyses revealed the presence of microbubbles with an average diameter of 3-5 μm on the treated fiber surface, with a coverage rate reaching 12%-15%. This phenomenon creates stress concentration points in the subsequent hot-pressing stage, leading to a decrease in interlaminar shear strength of approximately 18%. Utility Model Content

[0003] To address the technical problem of insufficient wetting of basalt fibers due to microbubbles on the surface, this invention provides a basalt fiber wetting box, which has the advantage of improving the fullness of basalt fiber wetting.

[0022] Figure 2 This is a cross-sectional structural diagram of the present invention. Detailed Implementation

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0026] See Figure 1 and Figure 2 This embodiment discloses a basalt fiber impregnation box, including a box body 10, a main shaft 20, a feed guide roller 30, and a discharge guide roller 40. The box body 10 has a rectangular parallelepiped structure with an open top, and is filled with impregnation liquid, the volume of which is between three-quarters and four-fifths of the box body's volume.

[0027] A main shaft 20 is provided inside the housing 10. The two ends of the main shaft 20 are respectively rotatably disposed on the front and rear sides inside the housing 10, and the main shaft 20 is arranged in a horizontal direction. Multiple coating parts 21 are provided on the surface of the main shaft 20. All coating parts 21 are densely distributed on the surface of the main shaft 20 and are randomly and irregularly distributed.

[0028] A feeding guide roller 30 is provided on one end of the top surface of the box 10. The two ends of the feeding guide roller 30 are rotatably connected to the inner wall of the box 10. A discharging guide roller 40 is provided on the other end of the top surface of the box 10. The two ends of the discharging guide roller 40 are also rotatably connected to the inner wall of the box 10.

[0029] The feed guide roller 30 is arranged parallel to the main shaft 20, and the discharge guide roller 40 is also arranged parallel to the main shaft 20. The feed guide roller 30 and the discharge guide roller 40 are located on the same horizontal plane. The main shaft 20 is located below the liquid surface of the immersion liquid and close to the bottom surface of the box 10.

[0030] During operation, multiple basalt fibers are fed into the housing 10 by passing over the top surface of the feed guide roller 30, then over the bottom surface of the main shaft 20, and finally over the top surface of the discharge guide roller 40 to complete the impregnation process. During this process, because the surface of the main shaft 20 is provided with multiple coating sections 21, when the basalt fibers come into contact with the coating sections 21, the microbubbles on the basalt fibers are detached from the basalt fibers by the action of the coating sections 21, thus ensuring that the basalt fibers are fully impregnated.

[0031] In one specific embodiment:

[0032] The coating part 21 is a raised structure on the surface of the main shaft 20. The coating part 21 is a spherical structure. Since all the coating parts 21 are arranged irregularly, when the basalt fiber comes into contact with the coating part 21, the basalt fiber is squeezed by the coating part 21 and generates sliding friction with the surface of the main shaft 20, so that the microbubbles are separated from the basalt fiber during the sliding process.

[0033] In another specific embodiment:

[0034] A scraper 50 is provided between the main shaft 20 and the discharge guide roller 40. By setting the scraper 50, excess impregnation liquid on the surface of basalt fiber can be scraped off, preventing excess impregnation liquid from dripping into areas outside the box 10.

[0035] In a preferred embodiment, there are two scrapers 50 with a gap between them. During use, the basalt fiber passes between the two scrapers 50, ensuring that both the upper and lower surfaces of the basalt fiber are thoroughly scraped. Furthermore, due to the accumulation of wetting liquid on the two scrapers 50 over long-term use, the scrapers 50 can also remove residual micro-air bubbles from the basalt fiber while scraping off the wetting liquid, and utilize the wetting liquid adhering to the scrapers 50 to wet any areas of the basalt fiber that have not yet been wetted.

[0036] In another preferred embodiment, the two scrapers 50 are close to each other on one side as scraping surfaces 51. The scraping surfaces 51 are provided with arc-shaped guide surfaces 52 on the side close to the main shaft. By setting the scraping surfaces 51, the surface of the basalt fiber is scraped, and by setting the arc-shaped guide surfaces 52, damage to the basalt fiber is avoided.

[0037] In another specific embodiment:

[0038] The diameter of the middle part of the discharge guide roller 40 is smaller than the diameter of its two ends. This technical solution can gather all the impregnated basalt fibers into a relatively narrow area to meet the needs of subsequent processes.

[0039] In a preferred embodiment, the middle part of the discharge guide roller 40 is a cylindrical main roller surface 41, and the two ends of the discharge guide roller 40 are curved converging surfaces 42, which allow the basalt fiber box to move on the cylindrical main roller surface 41.

[0040] In another specific embodiment:

[0041] A pressure roller 60 is arranged parallel above the feed guide roller 30, and there is a gap between the pressure roller 60 and the feed guide roller 30. By setting the pressure roller 60, the basalt fibers distributed in a narrow space can be squeezed into a wider range, so as to fully impregnate the basalt fibers.

[0042] Each end of the feed guide roller 30, the main shaft 20, and the discharge guide roller 40 is equipped with a baffle. By setting the baffle, basalt fibers are prevented from slipping off the ends of the feed guide roller 30, the main shaft 20, or the discharge guide roller 40.

[0043] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
