(107) The difference between this example and the example 3 above lay in:

(108) In step E, the protective glaze was a conventional protective glaze that was commercially available.

(109) The ceramic tiles decorated with dry particles prepared in examples 1-5 above and comparative examples 1-4 were tested for properties such as hardness, wear resistance, glossiness, and interlayer adhesion. The test results were as follows:

(110) TABLE-US-00032 Adhesion grade of Mohs Grade of wear dry particle hardness resistance Glossiness layer Example 1 >7 4 8? 0 Example 2 >7 5 7? 0 Example 3 >7 5 5? 0 Example 4 >7 4 6? 0 Example 5 >7 4 8? 0 Comparative 6.0 2 11? 2 example 1 Comparative 6.0 3 12? 1 example 2 Comparative 5.0 2 8? 1 example 3 Comparative 6.0 3 10? 1 example 4

(111) Wherein, the grade of wear resistance was tested according to a test method of GB/T 3810.7-2016 Standard, and the degree of surface wear traces of samples after grinding at a specific grinding speed was observed. The grade of wear resistance is divided into 0-5 grades, and specific grades are as follows:

(112) TABLE-US-00033 The number of grinding revolutions with visible Grade abrasion 0 100 1 150 2 600 3 750, 1500 4 2100, 6000, 12000 5 >12000

(113) The adhesion grade of the dry particle layer was tested according to a cross-cut test method of GB/T9286-98 Standard, and shedding of the dry particle layer of the test sample was observed. The adhesion grade of the dry particle layer is divided into 0-5 grades, and specific grades are as follows:

(114) TABLE-US-00034 Grade Description of situation 0 Edges are completely smooth, and there is no shedding. 1 There is shedding at an intersection of the cross-cut incision and/or an edge of the incision, but the effect of the cross-cut area is obviously not more than 5%. 2 There is shedding at an intersection of the cross-cut incision and/or an edge of the incision; an affected cross-cut area is obviously larger than 5%, but obviously not larger than 15%. 3 Part or all of a cutting edge is peeled off as large pieces, and/or partly or completely peeled off on different parts of each; an affected cross-cut area is obviously larger than 15%, but obviously not larger than 35%. 4 There are large fragments falling off along the edge of the incision, and/or partial or complete shedding appears in some squares; an affected cross-cut area is obviously larger than 35%, but obviously not larger than 65%. 5 A peeling degree exceeds 4 grades.

(115) According to the test data above, the ceramic tiles made by the disclosure had clear patterns, distinct layers, low glaze glossiness, good non-slip effects, obvious senses of dry particles, strong three-dimensional effects, rich colors, high hardness, high dry particle adhesion, and stable physical and chemical properties.

(116) In comparative example 1, instead of using the dry particle ink of the present disclosure to prepare a dry particle layer, the common spreading process of dry particles on the market was adopted, and the dry particles were spread directly after the glue was spread on the green body. Compared with the ceramic tile prepared in each example of the present disclosure, the surface of the ceramic tile produced in comparative example 1 had lower wear resistance, a wear resistance grade of 2, lower dry particle adhesion, a dry particle layer adhesion grade of 2, slightly higher glossiness (11?), lower slip resistance, a lower dry particle sense, and slightly lower hardness (6.0). This showed that, by spraying the dry particle ink on the surface of the green body of the ceramic tile, the jet printing can be carried out on a designated position on the surface of a green body, so that the texture sprayed can accurately correspond to the pattern-decorated texture, and the distribution uniformity and adhesion of dry particles on the surface of the green body were improved. And the first drying was carried out after the pattern decoration, so that the ink can be fully dried and formed. This prevented the subsequent spreading of the dry particles from causing fuzzy and chaotic pattern ink to undried ink, and improved the uniformity and adhesion of dry particles on the surface of the green body. Furthermore, after the dry particle ink was sprayed, the second drying process was carried out, which can initially heat the green body sprayed and printed with the dry particle ink. This can also avoid the phenomena of cracked bricks and exploded billets, which were caused by rapid firing of the green body sprayed and printed with dry particle ink during the subsequent firing process, and improve the adhesion and hardness of the dry particle layer. It can make the green body of the ceramic tile prepared and the dry particles form a stable bonding layer of body-particle-glaze. The ceramic tile of the present disclosure had an obvious sense of sand, a strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.

(117) Compared with example 3, in comparative example 2, the protective glaze was not sprayed at the end of the process, and the ceramic tile produced had lower surface wear resistance, a wear resistance grade of 2, lower dry particle adhesion (Grade 1), higher glossiness (12?), lower slip resistance, a lower dry particle sense, and slightly lower hardness (6.0). This showed that by spraying the protective glaze on the surface of the body after the dry particles was spread, and strictly controlling the spraying pressure and the amount of the protective glaze, the present disclosure can protect the dry particles and improve the adhesion of dry particles on the surface of the green body. This can avoid causing the dry particles to adhere to the kiln wall or roof as a result of the dry particles being blown away or suctioned away, thereby preventing the product from ash contamination, limestone caves, pinholes, etc. It can also make the green body of the ceramic tile and the dry particles form a stable bonding layer of body-glue-particle-glaze, thereby the ceramic tile had an obvious sense of sand, a strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.

(118) In the process of comparative example 3, compared with Example 3, drying was only performed once before spraying the dry particle ink, and there was no second drying after spraying the dry particle ink. The surface of the ceramic tile produced had lower wear resistance, a wear resistance grade of 2, lower dry particle adhesion (grade 1), higher glossiness (8?), lower slip resistance, a lower dry particle sense, and slightly lower hardness (5.0). This showed that by performing the second drying process after spraying the dry particle ink, the present disclosure can initially heat the green body sprayed and printed with the dry particle ink. This can also avoid the phenomena of cracked bricks and exploded billets, which are caused by rapid firing of the green body sprayed and printed with dry particle ink during the subsequent firing process, and improve the adhesion and hardness of the dry particle layer. It can make the green body of the ceramic tile prepared and the dry particles form a stable bonding layer of body-particle-glaze. The ceramic tile of the present disclosure had an obvious sense of sand, a strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.

(119) Compared with example 3, in comparative example 4, the protective glaze used in the process was a commercially available conventional protective glaze instead of the raw material formula of the protective glaze of the present disclosure; the ceramic tile produced had lower surface wear resistance, a wear resistance grade of 3, lower dry particle adhesion (Grade 1), higher glossiness (10?), lower slip resistance, a lower dry particle sense, and slightly lower hardness (6.0). This showed that spraying the protective glaze of the present disclosure can protect the dry particles to ensure that the dry particles are not blown off or suctioned off during the kiln firing process. It can also improve the adhesion of the dry particles on the surface of the green body, avoid causing the dry particles to adhere to the kiln wall or roof due to the dry particles being suctioned away, thereby preventing the product from ash contamination, limestone caves, pinholes, etc. At the same time, it can improve the wear resistance of the ceramic tile surface, reduce its glossiness, and have the effect of matte frosting. It can also make the green body of the ceramic tile and the dry particles form a stable bonding layer of body-glue-particle-glaze, thereby the ceramic tile has an obvious sense of sand, a strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.
