Description

Technical Field

[0001] The invention relates to the technical field of ceramics, and in particular to a preparation method of a reheated and fired ceramic tile and the reheated and fired ceramic tile. Background Art

[0002] Building ceramic tiles have smooth surfaces and rich patterns and colors, so they have two basic properties, namely, good cleanability and decorativeness. On the basis of ensuring easy cleanability, the decorativeness of ceramic tiles is the most important indicator for consumers. To a certain extent, it is the main factor affecting whether ceramic tile products are popular.

[0003] In recent years, with the application and popularization of inkjet printing technology, the market competition for building ceramic tiles is very fierce, especially the competition for ceramic tile patterns. There are many varieties of ceramic tiles, which can produce unlimited colors. The most common pattern types are imitations of natural stone and wood grain. Most of these ceramic tile processes are mainly heated and fired once. In order to improve market competitiveness and product added value, ceramic tile manufacturers have created products that are heated and fired again on the basis of products that are heated and fired once, thereby obtaining special decorative or functional properties of the products. Most of the ceramic tiles and curved ceramic tiles on the market are processed by the process of secondary heating and firing. When applying, designers will combine the original ceramic tiles fired once with ceramic tiles that are fired twice using the same color texture of the product. The decorative effect has the continuity of texture and color and the integrity of the overall decorative style, which improves the grade and taste of the decorative space.

[0004] However, even if the product fired twice has the same texture and color as the product fired once, the color of the product surface will change significantly after the second heating and firing. Products with the same color will become lighter or whiter, or yellower, redder, or bluer after the second heating and firing, making it difficult to keep the same color as the product fired once. This is mainly because the glaze of the product undergoes a new chemical reaction during the second heating and firing, producing a new phase; different phases absorb colors differently, which ultimately leads to color cast in the product fired twice. In this way, when ceramic tiles with the same texture but different colors are continuously spliced ​​together for decoration, there is a more obvious color difference, which affects the decorative effect and reduces the grade of the decorative space.

[0005] The color of the surface pattern will change greatly after the second heating and firing, and there is no clear target for the color and color depth after firing, so technicians must repeatedly adjust the color and rely on experience. Repeated color adjustment and repeated firing will result in low production efficiency of reheated ceramic tiles.

[0006] Therefore, the prior art has defects and needs to be improved and developed. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 It is a flow chart of a preferred embodiment of the method for preparing reheated fired ceramic tiles in the present invention.

[0040] Figure 2 It is a schematic flow chart of a preferred embodiment of the method for preparing reheated fired ceramic tiles in the present invention. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The color of the surface pattern will change greatly after the second heating and firing, and there is no clear target for the color and color depth after firing, so technicians must repeatedly adjust the color and rely on experience to explore. Such repeated color adjustment and repeated firing will lead to low work efficiency and extend the delivery time. In addition, designers have very strict requirements on the color difference of products after the second heating, and the existing process technology and methods are difficult to meet the requirements of the market terminal, which often leads to long delivery time, affects the construction progress, and even forces the construction plan to be modified due to the large color difference of the second heating products.

[0043] In view of the shortcomings of the prior art, the present invention provides a method for preparing re-heated and fired ceramic tiles, which reduces the color deviation of the ceramic tiles after re-heating and firing, and makes the color adjustment of the ceramic tiles produced by the second heating and firing have clear standards and directions, and the color deviation is controllable, which can improve the efficiency of product development and multi-batch online color adjustment, thereby stabilizing production and ensuring delivery time.

[0044] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of the method for preparing the reheated fired ceramic tile of the present invention. Figure 1 As shown, the method for preparing the reheated fired ceramic brick according to the embodiment of the present invention comprises the following steps:

[0045] Step S100: coloring the target glaze according to a predetermined coloring scheme to obtain a colored glaze, and using the colored glaze to prepare a preliminary fired ceramic sample.

[0046] In one embodiment, before step S100, the method further includes: determining a target ceramic tile to be processed, wherein the target ceramic tile is prepared by subjecting a target glaze to a heating and firing treatment; and using the target ceramic tile as a first standard sample.

[0047] Specifically, since ceramic tiles will change color after being heated again, there is no standard sample to refer to when adjusting the color, the target of each color adjustment becomes uncertain, and the color adjustment efficiency is low. In this embodiment, the target ceramic tile is used as the first standard sample to provide a reference when adjusting the color of the sample. The target ceramic tile of this embodiment refers to a ceramic tile product that needs to be heated and fired again, that is, a conventional ceramic tile product that is heated and fired once. Due to terminal design requirements, the product needs to be heated and fired again to give it a special decorative function. After heating and firing again, the color of the product will change significantly, so it is necessary to adjust the color of the target glaze so that it can obtain the original color after two firings.

[0048] In one implementation, step S100 specifically includes:

[0049] Step S110, cutting a target pattern of a predetermined size from the original design pattern of the first standard sample;

[0050] Step S120, coloring the target glaze according to a predetermined coloring scheme to obtain a colored glaze, and using the colored glaze to prepare a preliminary fired ceramic sample having the target pattern.

[0051] Wherein, the size of the initially fired ceramic sample is a predetermined size corresponding to the target pattern.

[0052] Specifically, refer to the texture color of the first standard sample and select the fixed size of the original design pattern. Among them, referring to the texture of the first standard sample is to accurately judge the color change trend of the pattern texture after reheating and firing. The fixed part size of the pattern is selected for the convenience of test and debugging. Especially for rock slab products with large specifications, the selection of local fixed pattern size for color adjustment can more accurately grasp the direction of color adjustment and reduce the labor intensity of technicians. For example, 300mm×600mm, 400mm×800mm specifications, etc., in order to facilitate experimental operation and reduce the labor intensity of technicians, this embodiment mainly takes 300mm×600mm size for operation.

[0053] The target glaze refers to the glaze of conventional ceramic tiles. This embodiment performs product color adjustment based on a glaze process suitable for reheating. Because the firing system of the reheated product is different, the glaze used is different from the glaze of conventional ceramic tiles. Therefore, a plurality of color adjustment schemes are predetermined to perform color adjustment tests on conventional glazes. When the ceramic tiles obtained after the reheating test are consistent with the first standard sample, it indicates that the glaze color adjustment is successful. When mass production is performed, the color adjustment can be performed according to the color adjustment scheme and mass production can be performed, thereby ensuring various performance indicators of the product during reheating and firing, and improving the efficiency of mass production.

[0054] like Figure 1As shown, the method for preparing the reheated fired ceramic tile according to the embodiment of the present invention further comprises the following steps:

[0055] Step S200: cutting the preliminary fired ceramic sample into a first preliminary fired sample and a second preliminary fired sample, and performing a reheating and firing treatment on the first preliminary fired sample to obtain a refired ceramic sample.

[0056] In one embodiment, the step S200 specifically includes:

[0057] Step S210, cutting the preliminary fired ceramic sample into a first preliminary fired sample and a second preliminary fired sample according to a pre-made cutting alignment line;

[0058] Step S220: reheat and sinter the first preliminarily sintered sample to obtain a refired ceramic sample.

[0059] Specifically, the cutting alignment line is made on the target pattern. The cutting alignment line is made at a fixed position of the selected pattern, and the selected pattern is basically a continuous pattern. The cutting alignment line is set to ensure the accuracy of the position of the cut sample, facilitate the pattern continuity of the subsequent color adjustment sample, and facilitate color comparison to find color differences.

[0060] In a specific embodiment, Figure 2 As shown, the sample after color adjustment and firing is cut into two small samples according to the pre-set cutting alignment line, namely sample 1 and sample 2. One of sample 1 and sample 2 is heated and fired again to obtain sample 3, which is the re-fired ceramic sample. In this embodiment, the sample obtained by color adjustment is cut according to the cutting alignment line to obtain two samples 1 and sample 2 with continuous patterns. Sample 1 or sample 2 is heated and fired again. The sample after reheating and firing has a change in color of the pattern, so it is called sample 3.

[0061] like Figure 1 As shown, the method for preparing the reheated fired ceramic tile according to the embodiment of the present invention further comprises the following steps:

[0062] Step S300: compare the refired ceramic sample with a predetermined first standard sample. If the comparison result between the refired ceramic sample and the first standard sample is consistent, the second preliminary fired sample is determined as a second standard sample.

[0063] Specifically, in the prior art, since there is no standard sample reference after reheating and firing during multi-batch mass production, each color adjustment needs to be refired, which takes a long period of time, requires high intensity of color adjustment by technicians, is difficult, has a lot of work, and is inefficient, which easily leads to a long delivery time and affects the decorative effect and construction progress of the terminal design. Therefore, this embodiment sets a second standard sample to provide a reference for the ceramic tiles that have been preliminarily heated and fired, so that they can be directly reheated and fired to obtain qualified products.

[0064] In one embodiment, the step S300 specifically includes:

[0065] Step S310, comparing the color hue and color depth between the refired ceramic sample and a predetermined first standard sample;

[0066] Step S320: If the color hue and color depth of the refired ceramic sample are consistent with the predetermined first standard sample, the second preliminary fired sample is determined as the second standard sample.

[0067] Specifically, the refired ceramic sample is compared with the first standard sample. When the color hue and color depth are consistent, the color adjustment is considered successful, and the second preliminary fired sample that has not been reheated and fired is determined as the second standard sample to facilitate mass production.

[0068] In one implementation, after step S310, the method further includes: if the color hue and / or color depth between the refired ceramic sample and the predetermined first standard sample are inconsistent, the predetermined color scheme is adjusted, and the target glaze is colored according to the adjusted predetermined color scheme.

[0069] Specifically, the refired ceramic sample is compared with the first standard sample. When the color hue is inconsistent, or the color depth is inconsistent, or both the color hue and the color depth are inconsistent, it proves that the color adjustment has failed and the color adjustment scheme needs to be changed. After changing the color adjustment scheme, the color adjustment of the target glaze is continued. After repeated experiments, the goal of achieving consistency in color hue and color depth between the refired ceramic sample and the first standard sample is finally achieved.

[0070] like Figure 1 As shown, the method for preparing the reheated fired ceramic tile according to the embodiment of the present invention further comprises the following steps:

[0071] Step S400: using the colored glaze to prepare preliminary fired ceramic tiles in batches, and comparing the preliminary fired ceramic tiles with the second standard samples.

[0072] In one implementation, the step S400 specifically includes: preparing preliminary fired ceramic tiles in batches using the colored glaze, and comparing the color hue and color depth between the preliminary fired ceramic tiles and the second standard sample.

[0073] Specifically, the color hue and color depth between the initially fired ceramic tile and the second standard sample are compared. If they are consistent, it means that the color of the initially fired ceramic tile is the same as that in the test, laying the foundation for the successful preparation of the reheated fired ceramic tile.

[0074] like Figure 1 As shown, the method for preparing the reheated fired ceramic tile according to the embodiment of the present invention further comprises the following steps:

[0075] Step S500: If the comparison result between the preliminary fired ceramic brick and the second standard sample is consistent, the preliminary fired ceramic brick is subjected to a reheating and firing treatment to obtain a reheated and fired ceramic brick.

[0076] In one embodiment, the step S500 specifically includes: if the color hue and color depth of the preliminary fired ceramic tile are consistent with those of the second standard sample, the preliminary fired ceramic tile is subjected to a reheating and firing treatment to obtain a reheated and fired ceramic tile.

[0077] Specifically, the reheated and fired ceramic tiles are obtained by directly reheating and firing the preliminarily fired ceramic tiles, thereby improving the production efficiency of the reheated and fired ceramic tiles.

[0078] In one implementation, after the color-adjusted glaze is used to batch-prepare preliminarily fired ceramic tiles, and the color hue and color depth of the preliminarily fired ceramic tiles are compared with the second standard sample, the method further includes: if the color hue and / or color depth of the preliminarily fired ceramic tiles are inconsistent with the second standard sample, the predetermined color-adjusting scheme is adjusted, and the target glaze is color-adjusted according to the adjusted predetermined color-adjusting scheme. When the preliminarily fired ceramic tiles are mass-produced again, steps S100-S500 are continued.

[0079] Specific embodiments are listed below for illustration.

[0084] Step A4: Cut a 300mm×600mm fixed area from the file;

[0085] Step A5, making cutting alignment lines on the cut texture;

[0086] Step A6, using the glaze that has been heated and fired again to adjust the color, and obtain a color-adjusted sample;

[0087] Step A7, cutting the color-adjusting sample into two samples with continuous textures according to a predetermined cutting alignment line;

[0088] Step A8, reheating and sintering one of the samples to obtain a sample;

[0089] Step A9, compare the color of the reheated sample with the standard sample, and continue to adjust the color until it is consistent with the color of the standard sample;

[0090] Step A10: The sample of the process scheme that is consistent with the color of the standard sample is determined as the standard sample to be heated and fired again, and mass production is carried out according to the process color adjustment scheme this time.

When adjusting the color with reference to the standard sample, there is no need to reheat and fire the color-adjusted sample multiple times and then compare it with the original standard sample.
