Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of ceramic filter discs, and specifically refers to a foam ceramic filter disc prepared from chemical zirconium and a preparation method thereof. Background Art
[0002] As a porous material, ceramic filter is widely used in the field of filtration and separation of liquids and gases. It intercepts and removes impurities through micropores and mesoporous structures.
[0003] Traditionally, most foam ceramic filters on the market are made from zirconium oxide as the main raw material. However, this preparation method has significant drawbacks: due to process limitations, the foam ceramic filters produced often contain more impurities, resulting in low product purity; at the same time, the presence of impurities also reduces the overall strength of the filter, making it vulnerable to damage in extreme environments such as high temperature and high pressure. More importantly, during the filtration process of high-temperature alloy solutions, these impurities may be brought into the alloy, seriously affecting the purity and performance of the high-temperature alloy, limiting its application and development in high-end fields such as aerospace and energy. Summary of the invention
[0004] In order to solve the above problems, the present invention proposes a foam ceramic filter sheet prepared by chemical zirconium and a preparation method thereof.
[0005] The technical solution adopted by the present invention is as follows: The present invention provides a foam ceramic filter prepared by chemical zirconium, comprising a ceramic filter, and the ceramic filter is provided with filter holes.
[0006] This scheme also discloses a method for preparing a foam ceramic filter sheet using chemical zirconium, which mainly comprises the following steps:
[0007] S1. The organic polymerizing agent and the chemical zirconium are mixed and stirred to form a flowing liquid having fluidity and adhesion;
[0008] S2. Immersing the porous sponge in the flowing liquid so that the flowing liquid is evenly hung on the porous sponge to form a liquid sponge;
[0009] S3. Dry the liquid sponge with a high temperature furnace;
[0010] S4. Maintain a vacuum reducing atmosphere in a high temperature furnace for high temperature sintering and molding.
[0011] Furthermore, the ratio of the organic polymerizing agent to the chemical zirconium is 4:6.
[0012] Furthermore, the organic polymerizing agent is an acrylate polymerizing agent.
[0013] The beneficial effects achieved by the present invention using the above structure are as follows:
[0014] (1) Using chemical zirconium as the main raw material, the prepared foam ceramic filter has excellent physical and chemical properties such as high melting point, high hardness, and corrosion resistance, which enables the filter to work stably for a long time in a high temperature and highly corrosive environment, thereby broadening its application range.
[0015] (2) The filtration efficiency is improved by evenly mounting a flowing liquid containing chemical zirconium on a porous sponge and solidifying it into a porous ceramic filter in a subsequent step. At the same time, the microporous structure of the ceramic material can effectively block impurities and ensure the filtration quality.
[0016] (3) The use of acrylic polymerizers as organic components has low toxicity and good environmental compatibility, which is beneficial to reducing environmental pollution during the production process. At the same time, maintaining a vacuum reducing atmosphere during high-temperature firing helps reduce the emission of harmful gases. BRIEF DESCRIPTION OF THE DRAWINGS
