Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide ceramic prefabricated plates, in particular to a silicon carbide ceramic prefabricated plate which is easy to splice. Background Art

[0002] Silicon carbide ceramic prefabricated plate is a high-performance ceramic material product, whose main component is silicon carbide. Silicon carbide is one of the hardest substances known, second only to diamond and cubic boron nitride. Therefore, silicon carbide ceramic prefabricated plate has extremely high hardness and excellent wear resistance, and can resist strong mechanical wear and scratches. The manufacture of silicon carbide ceramic prefabricated plate usually involves advanced technologies such as powder metallurgy and chemical vapor deposition. Among them, powder metallurgy is to mix silicon carbide powder with an appropriate amount of additives, press it into shape, and then sinter it at high temperature; chemical vapor deposition is to deposit a dense silicon carbide coating on the surface of the base material through chemical reaction. Among them, easy splicing is an important function of silicon carbide ceramic prefabricated plate.

[0003] For example, the Chinese patent "A Pressureless Sintered Silicon Carbide Ceramic Plate" with announcement number CN221031104U includes a main body, a bottom surface is arranged at the bottom of the main body, a waterproof device is fixedly installed above the bottom surface, an adhesive plate is arranged above the waterproof device, and an impact-resistant composite thermal insulation device is fixedly installed above the adhesive plate; the waterproof device includes water-emulsifiable asphalt, the top of the water-emulsifiable asphalt is fixedly connected to the bottom of the adhesive plate, and an expansion agent is fixedly installed on one side of the water-emulsifiable asphalt; the impact-resistant composite thermal insulation device includes crystalline ceramics, the bottom of the crystalline ceramics is fixedly connected to the top of the adhesive plate, the inner wall of the crystalline ceramics is provided with polyurethane, and the bottom of the expansion agent is fixedly installed with an external An additive, wherein a paper-based asphalt felt is arranged on one side of the additive, an air entraining agent is fixedly installed on the bottom of the paper-based asphalt felt, the bottom of the paper-based asphalt felt is fixedly connected to the top of the air entraining agent, one side of the water-emulsified asphalt is fixedly connected to one side of the expansion agent, a glass fiber mesh grid is fixedly installed on the bottom of the polyurethane, a nitride is arranged on one side of the glass fiber mesh grid, a polystyrene resin is fixedly installed on one side of the nitride, one side of the nitride is fixedly connected to one side of the polystyrene resin, the inner wall of the crystalline ceramic is fixedly connected to the surface of the polyurethane, the top of the waterproof device is fixedly connected to the bottom of the adhesive plate, and the top of the adhesive plate is fixedly connected to the bottom of the impact-resistant composite thermal insulation device.

[0004] Although the above-mentioned prior art can realize the splicing of silicon carbide ceramic prefabricated panels, in actual use, on the one hand, the usual splicing method makes the silicon carbide ceramic prefabricated panels not fixed firmly enough. The usual fixing method is to fix them by squeezing between the panels, which causes the silicon carbide ceramic prefabricated panels to easily fall off under the action of external forces, thereby affecting the fixing effect of the silicon carbide ceramic prefabricated panels. On the other hand, it is difficult to protect the surface of the silicon carbide ceramic prefabricated panels. The surface layer of the silicon carbide ceramic prefabricated panels is easily damaged during the use of the silicon carbide ceramic prefabricated panels, thereby shortening the service life of the silicon carbide ceramic prefabricated panels. Therefore, it does not meet the existing needs. In this regard, we propose a silicon carbide ceramic prefabricated panel that is easy to splice. Utility Model Content

At this time, put the limit strip on the other side of the male plate into the slide groove on the other mother plate, and fix the other mother plate. Repeat the above steps to splice the silicon carbide ceramic prefabricated panels, thereby improving the firmness of the splicing of the silicon carbide ceramic prefabricated panels.

[0017] 2. The utility model can improve the protective performance of the surface of the silicon carbide ceramic prefabricated plate through the first wear-resistant layer and the second wear-resistant layer. When the male plate and the mother plate are spliced ​​and used, the first wear-resistant layer and the second wear-resistant layer set at this time can provide protection for the surface of the male plate and the mother plate. The first wear-resistant layer and the second wear-resistant layer can effectively reduce the damage caused by the friction between the plates, and also improve the wear resistance of the surface of the male plate and the mother plate. At the same time, the first high-temperature resistant layer and the second high-temperature resistant layer set can improve the high-temperature resistance of the silicon carbide ceramic prefabricated plate, and provide high-temperature protection for the remaining protective coatings, thereby extending the service life of the remaining protective coatings.
