Figure BDA0003865104550000121
Figure BDA0003865104550000131
Remarking: as in fig. 1-5, the white stripes on the surface of the brick body are glittering effects.
Description of the drawings:
1. comparing example A with comparative example E1, comparative example E1 applies the common dry granules in step (2) instead of the localized crystalline dry granules of example A, and comparative example E1 does not use the localized crystalline dry granules; in the scheme, the positioning crystallization dry particles can effectively improve the flashing effect, and can be realized after being combined with the common dry particles and the protective glaze, so that the continuous flashing effect can be realized on the brick body; thus, the surface of comparative example No. E1 had no pits, but the glittering effect of the surface was insufficient, as shown in FIG. 5. The embodiment A uses the positioning crystallization dry grains, the flashing effect of different positions of the brick body is continuous, and no pit exists; the formula of the positioning crystallization dry particles of the scheme is used, so that the flash effect of the blank can be effectively improved.
2. As can be seen from the comparison between example A and comparative example E2, in comparative example E2, after the step (3), the mixture is directly dried and then sintered, and the ordinary dry particles and the protective glaze are not applied again. In the scheme, the common dry particles can be matched with the positioning crystallization dry particles for use, so that the problem of reduced flash effect caused by whitening when the positioning crystallization dry particles are easy to agglomerate is prevented; therefore, the glittering effect of comparative example E2 is insufficient, as shown in fig. 5; in the embodiment a, after the step (3) is executed, the step (4) is continued to present the flash effect, as shown in fig. 1; it shows that after the protective glaze is applied in the step (3), the step (4) is required to be performed to continue applying the common dry particles and the protective glaze, and the flash effect can be generated.
3. As can be seen from the comparison of example A with comparative example E3, comparative example E3 does not carry out step (5), i.e., the green brick is not polished after firing; in the scheme, the positioning crystallization dry particles need to be polished to generate a flashing effect; polishing the decorative surface, and removing the raised parts of the partially positioned crystallized dry particles to smooth the water ripples of the glaze surface of the decorative surface and finally eliminate pits; thus comparative example E3 had no sparkling effect, as in fig. 6. The green brick of example A was polished to smooth the decorative surface, so that the flashing effect was obtained at different positions of the green brick, and the flashing positions were continuous and no pits existed, as shown in FIG. 1.
In conclusion, the decoration surface of the scheme needs to arrange the protection glaze twice, the protection glaze is distributed on the positioning crystallization dry particles for the first time, the protection glaze is distributed on the second common dry particles for the second time, and the continuous flashing effect of the brick body can be formed by drying, sintering and polishing, so that the problem that the flashing effect formed by the positioning crystallization dry particles of the decoration surface in the prior art is relatively convex to form the existing pits is effectively solved.
The technical principles of the present solution have been described above with reference to specific embodiments. These descriptions are made for the purpose of illustrating the principles of the present solution and are not to be construed in any way as limiting the scope of the present solution. Based on the explanations provided herein, a person skilled in the art will be able to conceive of other embodiments of the present solution without inventive effort, which shall fall within the scope of protection of the present solution.
