water spraying amount on the surface of the green brick: 5 ~ 10 g/dish (tray size 200X 600mm, same below)
Dry particle glaze specific gravity: 1.55-1.58; throwing glaze weight: 16 +/-2 g/disc;
after glazing is finished, the obtained green body is fired, and the firing process can be as follows:
and (3) firing in a kiln: a roller kiln;
firing temperature: 1150 ℃;
and (3) firing period: and (5) 50 min.
The flexural strength of the rock plate is tested by using an SKZ flexural and compressive resistance tester, the afterglow brightness of the glaze (including initial afterglow strength and afterglow strength after 60min of luminescence) is measured by using GB/T24981.2-2020, and the results are shown in Table 1.
The phosphors used in examples 1 to 5 and comparative examples 1 to 2 according to the present embodiment are commercially available green phosphors.
TABLE 1
As can be seen from the test results in Table 1, the fluorescent glazes provided in the embodiments 1 to 5 of the present invention have good mechanical strength, high afterglow luminance, and low decay of afterglow luminance after 60min of operation. While comparative examples 1 and 2 have no nano-magnesium sulfide and boron nitride added, respectively, although the initial value of the afterglow intensity is similar to that of example 5, the afterglow intensity is significantly reduced after 60min of operation, while comparative example 3 has no nano-magnesium sulfide and boron nitride added, which results in further reduction of the afterglow intensity after 60min of operation.
The applicant states that the present invention is illustrated by the above examples to show the detailed process equipment and process flow of the present invention, but the present invention is not limited to the above detailed process equipment and process flow, i.e. it does not mean that the present invention must rely on the above detailed process equipment and process flow to be implemented. It should be understood by those skilled in the art that any modification of the present invention, equivalent substitutions of the raw materials of the product of the present invention, addition of auxiliary components, selection of specific modes, etc., are within the scope and disclosure of the present invention.
