/ Gloss degree/° C
Example 1 96
Example 2 95
Example 3 97

As can be seen from the table above, the cryolite ceramic tile obtained by the preparation process has a good flashing effect because the surface is smooth, the glossiness of the whole ceramic tile is good, and the specific glossiness is over 95 degrees.

Comparative example 1

The conditions in this example are the same as in example 3, except that: this comparative example did not have a secondary application of dry particles (only glitter glaze applied) to the tile surface, followed directly by the drying, firing and polishing steps.

The performance of comparative example 1 was tested, and the evaluation results of the flashing effect were: example 3> example 1> example 2 > comparative example 1, and this comparative example 1 (glitter particles worn away during sanding and more pits present on the surface) was significantly less glitter and also less glossy than the first 3 examples after visual inspection, as shown in the following table:

it can be seen from the above table that because the secondary drying is not carried out, the surface of the ceramic tile is covered with more flash particles, when the ceramic tile is polished in the subsequent process, the grinding tool directly contacts with the flash particles, namely zircon, so that part of the flash particles can be worn away, and because the hardness of the flash particles is higher, part of cracks and pits can be caused to appear on the surface of the ceramic tile, and the surface of the ceramic tile is uneven, so that the glossiness of the surface of the ceramic tile is synchronously reduced and is far lower than the flash effect of the cryolite ceramic tile in the scheme.

Example 4

The conditions in this example are the same as in example 3, except that: the zircon grain composition used in this example was: the content of 30-40 meshes is 52.5%, the content of 40-60 meshes is 46%, and the content of less than 100 meshes is 1.5%.

Example 5

The conditions in this example are the same as in example 3, except that: the zircon grain composition used in this example was: 98 percent of 30-40 meshes and 2 percent below 100 meshes.

Example 6

The conditions in this example are the same as in example 3, except that: the zircon grain composition used in this example was: 52.5 percent of 30-40 meshes, 26 percent of 40-60 meshes, 20 percent of 60-80 meshes and 1.5 percent below 100 meshes.

The results of practical observation of examples 4-6 were: example 4 > example 6> example 5> example 3> example 1> example 2 > comparative example 1. As the particles were formulated in this set of examples, the corresponding cryolite tiles also varied in sparkle effect. Correspondingly, the grain composition of the ceramic tile (zircon) is 30-40 meshes accounting for 52.5%, 40-60 meshes accounting for 46%, and 1.5% below 100 meshes has the best glittering effect, and is far larger than that of other embodiments; then, after the particle grading is increased to 4 types of particles with the particle sizes-example 6, the glittering effect is not increased or decreased, so that the preferable particle grading of the scheme is that the particle grading is 48-57% of 30-40 meshes, 40-50% of 40-60 meshes and less than or equal to 3.0% of 100 meshes; similarly, when the (zircon) grain composition is reduced to 2 post-examples 5, the corresponding sparkle effect is worse than that of example 6.

Example 7

The conditions in this example are the same as in example 3, except that: the specific gravity of the glittering glaze used in the present example was 1.92g/ml, application amount is 348g/m2(ii) a The dry pellets had a specific gravity of 1.35g/ml and an application amount of 470g/m2

Example 8

The conditions in this example are the same as in example 3, except that: the glitter glaze used in this example had a specific gravity of 2.5g/ml and was applied in an amount of 465g/m2(ii) a The dry granules had a specific gravity of 1.8g/ml and an application amount of 588g/m2

Example 9

The conditions in this example are the same as in example 3, except that: the glitter glaze used in this example had a specific gravity of 1.3g/ml and was applied in an amount of 275g/m2(ii) a The dry granules had a specific gravity of 1.1g/ml and an application amount of 370g/m2

The performance tests of examples 7 to 9 were carried out, and the evaluation results of the glitter effect were: example 7>Example 4 > example 6>Example 8>Example 5>Example 3>Example 1>Example 2>Example 9 "comparative example 1. In order to further improve the flash effect of the cryolite ceramic tile, the application also verifies the influence of glazing parameters on the flash effect, and finally obtains that the specific gravity of the flash glaze is 1.90-2.1g/ml and the application amount is 400g/m for 300-one materials when the flash glaze is applied for the first time2(ii) a When the dry particles are applied for the second time, the specific gravity of the dry particles is 1.30-1.45g/ml, and the application amount is 400-2The flashing effect of the tile is best in this range. Overall, the volume of applying of flash of light frit and dry grain is all comparatively moderate, and the setting of above parameter can guarantee basically that the dry grain layer on surface is worn and torn off when the polishing, and the inside flash of light frit surface has to grind to a very shallow part, and zircon is thrown to the regional quilt of only top small range because the main part is all thrown glaze raw materials parcel, and consequently, can not cause the pit phenomenon, and slightly polish to that zircon layer flash of light effect is better. The results of the corresponding tests of examples 7-9 can verify that when the application amount and specific gravity are large (example 8), the flashing effect is not even as good as that of example 6; when the application amount and the specific gravity were small (example 9), the glittering effect was greatly reduced because of the small application amount.

From the above detection results, the chemical composition of the glaze polishing of the present invention needs to be limited to SiO2:48.5-55.8%,Al2O3:12.9-17%,Fe2O3:0-0.45%,CaO:9-15%,MgO:3-7%,Na2O:2.8-6%,K2O:0.3-2.0%,ZnO:1.5-6%,B2O3: 0.3-1.6%, BaO: in the range of 4.2-8%, otherwise preparedThe obtained polished tiles have relatively poor glittering effect, just as the glaze polishing compositions adopted in examples 1-9 and the glaze polishing compositions adopted in examples 10-12 have better glittering effect in examples 10-12, and the glittering effect of example 10 is obviously better than that of examples 11 and 12 as a preferred example; in addition, from the results of the tests in examples 10 to 12, it can be seen that B is the number B in this case2O3: CaO: the ratio of BaO to BaO is controlled to be 1: (12-12.8): (5-6), the glittering effect is better, and when the component proportion of the glittering particles, the glittering particles and the polishing glaze is controlled, the glittering particles are better fused in the polishing glaze, cannot be worn away during polishing, and the pits 2 are fewer.

As shown in fig. 1 to 2, the surface of the cryolite tile obtained in example 10 and comparative example 1 is observed, and as shown in fig. 1 to 2, the surface of the cryolite tile obtained in example 13 is not substantially provided with pits 2, the corresponding antifouling effect is also good, and the zircon glittering particles 1 are not substantially absent on the surface of the tile, so that the overall glittering effect is good, and as shown by the detection results of the above examples and comparative examples, the glittering effect of example 10 is higher than that of comparative example 1 by multiple grades, so that the cryolite tile with excellent glittering effect can be obtained by the above preparation process and parameters. As shown in fig. 2, the surface of comparative example 1 had many pits 2, relatively poor glossiness, and low glitter effect.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications and equivalents of the technical solutions that can be directly or indirectly applied to other related fields without departing from the spirit of the present application are intended to be included in the scope of the present application.
