[0005] The utility model aims to provide a base tube with an R-angle flanged explosion-proof porcelain structure to solve the problems raised in the above-mentioned background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A base tube with an R-angle flanging explosion-proof porcelain structure, comprising:
[0008] A base tube, a bottom glaze layer and a surface glaze layer are sequentially arranged on the inner wall of the base tube, and an R-angle flanging structure is arranged at the pipe mouth of the base tube.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 5 , the utility model provides a technical solution:
[0025] Embodiment 1: A base tube with an R-angle flanging explosion-proof porcelain structure, comprising:
[0026] A base tube 1, a bottom glaze layer 3 and a surface glaze layer 4 are sequentially arranged on the inner side wall of the base tube 1, and an R-angle flanging structure is arranged at the tube mouth of the base tube 1.
[0027] R-angle flanging structure, the R-angle flanging structure includes a bottom glaze layer 3, an explosion-proof mesh layer 5 and a surface glaze layer 4 which are sequentially arranged on the R-angle 2. First, sandblasting is performed at the R-angle 2 and the entire base tube 1. Glaze is sprayed on the surface of the base tube 1 and the R-angle 2 through a spraying process and then sintered to form a bottom glaze layer 3. An explosion-proof mesh layer 5 is welded on the surface of the bottom glaze layer 3 of the R-angle 2 by covering, spot welding, or brazing. The explosion-proof mesh layer 5 is a metal wire mesh composed of metal filaments. The effect of adding a metal wire mesh is similar to that of adding steel bars to cement and a fiber winding layer (glass fiber mesh cloth) to a FRP pipe. Both are means for increasing product strength and adhesion. The explosion-proof mesh layer 5 uses a metal wire mesh with a thickness of less than 1 mm and a mesh number of greater than 50. It is found through testing that the surface glaze layer 4 can be sintered well and the strength and adhesion of the surface glaze layer 4 can be increased. Then, glaze is sprayed on the surface of the metal wire mesh and the bottom glaze layer 3 through a spraying process and then sintered to form a surface glaze layer 4.
[0028] The metal wire itself has a certain ability to wet ceramics, and the metal wire has a certain affinity with ceramics. Under high temperature, a compound between metal and ceramic can be formed. No defects will occur between ceramics and the metal wire, thus causing a potential risk of ceramic explosion.
[0029] Embodiment 2: The only structural difference from Embodiment 1 is that an explosion-proof mesh layer 5 is welded to the R corner 2 and the bottom glaze layer 3 in the base tube 1 by covering, spot welding, or brazing, and then glaze is sprayed on the surface of the metal wire mesh and the bottom glaze layer 3 by a spraying process and then sintered to form a surface glaze layer 4.
[0030] Implementation effect: Because an explosion-proof mesh layer 5 is provided between the bottom glaze layer 3 and the surface glaze layer 4, the ceramic of the surface glaze layer 4 can be divided into blocks, which plays a role of tightening and strengthening, and is less affected by tensile and compressive stresses. Adding the explosion-proof mesh layer 5 can change the ceramic structure and increase the impact force caused by tensile stress.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
