TABLE 1 comparison of the Properties of examples A-D and comparative examples E1-E3
Remarks: as shown in fig. 1-5, the white strips on the surface of the brick body are flashing effects.
Description:
1. as can be seen from the comparison of example A with comparative example E1, comparative example E1 was provided with conventional dry granules in step (2) instead of the oriented crystalline dry granules of example A, and comparative example E1 did not use oriented crystalline dry granules; in the scheme, the positioning crystallization dry grain can effectively improve the flashing effect, can be realized after being combined with the common dry grain and the protective glaze, and can realize continuous flashing effect on the brick body; thus, the surface of comparative example E1 had no pits, but the effect of the flash on the surface was insufficient, as shown in FIG. 5. In the embodiment A, the crystal dry grains are positioned, the flashing effect of different positions of the brick body is achieved, the flashing is continuous, and pits are not formed; the formula of the positioning crystallization dry particle with the scheme is illustrated, and the flashing effect of a blank body can be effectively improved.
2. As is evident from the comparison of example A and comparative example E2, comparative example E2 was directly dried and then fired after step (3), and no conventional dry granules and protective glaze were applied. In the scheme, the common dry particles can be matched with the positioning crystal dry particles to prevent the problem of reduced flashing effect caused by whitening when the positioning crystal dry particles are easy to agglomerate; therefore, the flash effect of comparative example E2 is insufficient as shown in fig. 5; in embodiment A, after executing step (3), proceed to step (4), which presents a flashing effect, as shown in FIG. 1; it is described that after the protective glaze is applied in the step (3), the step (4) is needed to continuously apply the common dry grains and the protective glaze, so that the flashing effect can be achieved.
3. As can be seen from the comparison of example A with comparative example E3, comparative example E3 did not perform step (5), i.e., the green brick was not polished after firing; in the scheme, the positioning crystal dry grains need to be polished to generate a flashing effect; polishing the decorative surface, namely polishing the protruding part of the crystalline dry grain with the partial positioning, so that the water ripple on the glaze surface of the decorative surface is smooth, and finally, no pit exists; thus comparative example E3 does not have a sparkling effect as shown in fig. 6. The green bricks of the embodiment A are polished to flatten the decorative surface, the flashing effect of different positions of the brick body is achieved, the flashing positions are continuous, and pits are not formed, as shown in fig. 1.
To sum up, the decoration surface of this scheme needs to arrange twice protection glaze, and first time protection glaze cloth is applied to location crystallization dry grain, and second time protection glaze cloth is applied to second ordinary dry grain, and after drying and sintering, polishing again can form the continuous flash effect of brick body, has effectively solved the flash effect that the decoration surface location crystallization dry grain formed and has relatively protruded problem of forming present pit in prior art.
The technical principle of the present solution is described above in connection with the specific embodiments. The description is only intended to explain the principles of the present solution and should not be construed in any way as limiting the scope of the present solution. Based on the explanations herein, other embodiments of the present solution will be apparent to those skilled in the art without undue burden, and such modifications will fall within the scope of the present solution.
