The breaking strength of the ceramic tile is more than 30Mpa, so that the thickness of the ceramic tile is only 10-14 mm; the natural marble has low breaking strength, generally about 10Mpa, because of the nature and the large thickness, generally between 20mm and 25 mm; thirdly, the water absorption rate is low, and the antifouling property is strong; fourthly, the processing is easy and the product is not easy to break; fifthly, the selected materials are high in quality and stable in supply; sixth, strict monitoring, rejection of color differences, and the like.
However, the marble-imitated ceramic tiles appearing on the market at present have the following defects: (1) at present, the traditional dry color mixing process is always on the basis of 3 mixed colors, the printed color is single, the pattern is simple, and the vivid effect of being rich in natural marble patterns and having the same surface and inner surface is difficult to achieve. And the problem of 'look-like and look-like' cannot be solved. Namely, the prior marble-imitated ceramic tile has the defects of unrealistic decorative effect, relatively unnatural transition between a blank body and a cover glaze and poor pattern definition. (2) The traditional printing process cannot realize the screen overprinting technology with various colors. (3) The glaze on the surface of the ceramic tile has insufficient wear resistance, and the wear resistance is generally below 1500 turns.

Further, the dry color mixing and distributing process of 4 mixed 6 colors in the step eight is realized by adopting a dry color mixing and distributing vehicle, and comprises the following steps:
(1) the dry method color mixing material distribution vehicle comprises a hollow and solid roller device, three plane material distribution devices, a material distribution screen and a pneumatic flashboard;

(4) the cloth separating screen in the step (1): the color material partition screen is composed of irregular small squares with different shapes and sizes to form a total color material partition screen which is equivalent to a color material storage area;
the material pushing device mainly has the main effects of preventing powder particles from generating rolling type layered displacement in the material pushing process of the material distributing vehicle and effectively fixing the patterns of the early-stage colored powder shapes. Meanwhile, after each brick is pressed, the bottom powder and the bottom film must be completely absorbed, so that the missing mottled particles are prevented from entering the surface of the next brick to influence the pattern and color generation of a blank body;
(6) the pneumatic flashboard in the step (2) is used as the power control of the dry-process color mixing material distribution vehicle;
further, selecting blank raw materials in the step one: the whiteness of the selected blank raw material is 60-70 degrees.
In the design, the selection of the blank raw materials is also very exquisite, the traditional blank generally has the whiteness below 39 degrees, and the whiteness of the blank raw materials selected for the project is about 65 degrees. In the traditional method, a zirconium silicate raw material is generally added in order to increase the whiteness of the raw material, and the zirconium silicate is not added in the project from the environmental protection perspective and mainly used as a first selected raw material; secondly, some chemical-grade raw materials are added to improve the whiteness of the blank;
further, the pigment in the step one is selected: in order to ensure the stable color development of the green brick, the pigment is required to be not agglomerated and to have good adsorbability with powder particles; when the granularity is smaller than 325 meshes, the water content is controlled to be less than 1 percent, and a better color mixing effect can be obtained.
The invention aims at the pigment, combines with Itacha enterprises in pigment selection, and requires that the pigment does not agglomerate or agglomerate and has good adsorbability with powder particles in order to ensure stable color development of green bricks. The project passes a series of influence factor tests, such as: the fineness of the pigment and the moisture influence the color mixing effect.
Influence of fineness and moisture on color mixing effect
As can be seen from the table, the fineness and moisture have a great influence on the color mixing effect. In the project, when the granularity is less than 325 meshes, the moisture content is controlled to be less than 1 percent, and a better color mixing effect can be obtained.
Further, the 6-12 screen overlay inkjet technologies in the step eight are implemented by using inkjet + multi-layer screen overlay technologies, and the inkjet + multi-layer screen overlay technologies adopt the following steps:
(2) the skip printing process of the overprinting matched with the ink-jet and screen printing is completed, and the following steps are adopted:
B. selecting five-color four flowers with random skip printing;
B. in order to facilitate screen jumping, marks of 1, 2, 3 and 4 are marked on each brick, and four bricks are in a queue;
C. the skip printing process is completed by sending out an instruction to the induction electric eye on the glaze line; if the blank body of the No. 1 ink-jet printing is marked, a silk screen printing instruction is received on a glaze line, all the corresponding No. 1 silk screens complete the No. 1 overprinting process, and the No. 2, 3 and 4 silk screens are subjected to skip printing;
(2) controlling the offset or deviation of the printing machine within 0.1 mm;
in the invention, the offset or deviation of the traditional printing machine is between 0.4mm and 3mm, and the offset or deviation problem can not occur in overprinting when the skip printing is carried out on the colors between different screens; the design controls the offset or deviation of the printing machine within 0.1 mm;
(3) the fineness of the glaze printing ball mill is strictly controlled, the fineness is improved from the original 160 meshes to 250 meshes and passes through the screen, and the defects of screen points and reticulate patterns are overcome. The effect that the surface and the inside of the patterns of the green body and the glaze are the same can be effectively realized; in order to realize the 6-12 silk screen superposition ink-jet technology, the design greatly improves the requirements on the mesh number and the grid number of the silk screen from the original 140 meshes to 180 meshes. The fineness of the glaze printing ball mill is strictly controlled, the fineness is improved from the original 160 meshes to 250 meshes and passes through the screen, and the defects of screen points and reticulate patterns are effectively overcome.
Step five: the special-designed diamond frit glaze is adopted to control the initial melting and melting temperature of the frit glaze, improve the wear resistance and transparency of the glaze, and realize that the wear resistance of the ceramic tile reaches 2100-.
In the invention, the wear resistance of the traditional ceramic tile is about 2000 revolutions generally, and in order to improve the wear resistance of the ceramic tile, the project starts from a glaze formula and develops a diamond fritted glaze with high wear resistance. Therefore, the wear resistance of the product can reach 2100-.
In order to improve the wear resistance of the ceramic tile, a diamond melting block particle is developed to solve the problem of the wear resistance of the ceramic tile. During development, multiple sets of frit formulations, denoted frit 1, frit 2, and frit 3, were tested. By researching the components and ingredients of the formula and analyzing the initial melting temperature and the melting temperature of the components, the frit formula with high wear resistance and good transparency is finally obtained.

3# prescription 1112 1180 Is poor 8000
From the recipe of formulation # 2 above, it was found that the diamond nugget had an onset temperature of 1095 ℃ and a melting temperature of 1160 ℃. The conventional frit particles have an onset melting temperature of 945 ℃ and a melting temperature of 1020 ℃. Therefore, the project adopts the high-temperature slow-firing technology to obtain the product with the best transparency, the most stable color development and the highest wear resistance (up to 4000 revolutions).
