[0024] Embodiment 1
[0025] See also Figure 1 The present invention provides a method for sorting tiles, and the method comprises the following steps:
[0026] S100: obtaining a first ceramic tile sample, and sequentially performing a first cutting process and a first grinding process on the first ceramic tile sample to obtain a first ceramic tile blank, wherein the first ceramic tile blank has a first preset size;
[0027] S200: performing a first drying process and a first soaking process on the first ceramic tile blank in sequence, and obtaining a first preset weight and a second preset weight of the first ceramic tile blank in sequence;
[0028] S300: Calculating a first water absorption rate of a detection area of the first ceramic tile blank according to the first preset weight and the second preset weight;
[0029] S400: Determine the grade of the current batch of tiles. When the first water absorption rate is less than 0.1%, the current batch of tiles is determined to be the first grade. When the first water absorption rate is between 0.1% and 0.13%, the current batch of tiles is determined to be the second grade or the third grade. When the first water absorption rate is greater than 0.13%, the current batch of tiles is determined to be the third grade.
[0030] In some embodiments, the first tile sample in S100 is a tile on the kiln position with the lowest temperature in a batch of kiln rings, and the tile may be a polished tile, a glazed tile, a vitrified tile, an antique tile, etc., which are not listed one by one here.
[0031] In some embodiments, the specific operation of the first cutting process in S100 is: cutting the center position of the first tile sample by a cutting machine to obtain the first tile sample with a size of 100 mm*150 mm. The first tile sample has a first preset thickness.
[0032] In some embodiments, the specific operation of the first grinding process in S100 is: placing the cut first tile sample on a workbench, fixing the position of the first tile sample, and grinding the inspection area of the first tile sample by a grinder to obtain the first tile blank having a second preset thickness.
[0033] In some embodiments, during the first grinding process, the grinding needs to be uniform and smooth to make the grinding surface smooth, so as to avoid uneven thickness and bumpy grinding surface, and after grinding, a measuring device needs to be used to measure whether the grinding size meets the thickness requirement range, such as using a vernier caliper for measurement. The thickness requirement range of the first ceramic tile samples of various thicknesses after grinding is shown in Table 1, and the thickness before grinding in Table 1 is the first preset thickness, and the thickness after grinding is the second preset thickness.
[0034] Table 1 Thickness requirements of ceramic tiles after grinding
[0035] Thickness before grinding (mm) Thickness after grinding (mm) 7.8 4.6～5.0 9.5 6.3～6.7 9.0 5.8～6.2 10.5 7.3～7.7 10.8 7.6～8.0 12.0 8.8～9.2
[0036] In some embodiments, the detection zone is located at the four corners or the central axis of the first tile sample, the detection zone is a quadrilateral, and the size of the detection zone is smaller than the size of the first tile sample.
[0037] In other embodiments, the detection area may also be circular, pentagonal, hexagonal, heptagonal, etc., which are not listed here one by one.
[0038] In some embodiments, the first ceramic tile sample is subjected to the first grinding process in a first preset manner or a second preset manner. When the first ceramic tile sample is subjected to the first grinding process in the first preset manner, the time of the first drying process is the first preset time. When the first ceramic tile sample is subjected to the first grinding process in the second preset manner, the time of the first drying process is the second preset time. The second preset time is longer than the first preset time.
[0039] In some embodiments, the first preset mode is dry grinding, and the first preset time of the first drying process after dry grinding is 30 minutes. The second preset mode is wet grinding, and the second preset time of the first drying process after wet grinding is 120 minutes.
[0040] In some embodiments, the specific operation process of performing the first drying treatment on the first ceramic tile blank in S200 is: placing the first ceramic tile blank in an oven, and adjusting the temperature of the oven to 200° C. so that the first ceramic tile blank can constantly maintain the first preset weight.
[0041] In some embodiments, the specific operation process of performing the first soaking treatment on the first ceramic tile blank in S200 is: set the vacuum pressure value of the vacuum container to 9, turn the hand wheel to open the upper cover of the vacuum container, insert the first ceramic tile blank of the first preset weight into the slot of the sample rack of the vacuum container, and turn the hand wheel in the opposite direction to close the upper cover of the vacuum container. Pour water into the water tank so that the water level is at the red label water level line, turn on the main power of the vacuum container, that is, press the "Run" button on the operation panel to make the vacuum container automatically complete the process of vacuuming, maintaining pressure, filling water, soaking, and draining water, and the pressure holding time is 30min to 40min. When the "Stop" light on the operation panel is on, turn the hand wheel to open the upper cover of the vacuum container and take out the first ceramic tile blank. The first ceramic tile blank has the second preset weight after being wiped dry.
[0042] In some embodiments, the drying process of the first ceramic tile blank after being taken out of the vacuum container is as follows: use suede to wipe off water marks on the bottom and sides of the first ceramic tile blank, and then use a fan to blow on the front and back sides for 20 seconds each, until the ceramic tile blank turns slightly white.
[0043] In some embodiments, the first preset weight and the second preset weight are both obtained by weighing with an electronic scale with an accuracy of 0.01.
[0044] In some embodiments, the second preset weight is greater than the first preset weight, and the second preset weight has a preset weight difference with the first preset weight. The first water absorption rate is equal to the percentage of the preset weight difference to the first preset weight.
[0045] In some embodiments, the risk of tile cutting cracking is positively correlated with the first water absorption rate. The third level of tile cutting cracking risk is greater than the second level of tile cutting cracking risk, and the second level of tile cutting cracking risk is greater than the first level of tile cutting cracking risk.
[0046] In some embodiments, the first grade of tiles are qualified tiles, and the first grade of tiles have a lower risk of cracking during subsequent cutting and use, and the first grade of tiles are high-quality tiles.
[0047] In some embodiments, the second grade tiles are in a borderline qualified state, and the second grade tiles have a greater risk of cracking during subsequent cutting and use. The second grade tiles are inferior grade tiles and are not suitable for sale.
[0048] In some embodiments, the third grade tiles are unqualified tiles, and the third grade tiles have a greater risk of cracking during storage, transportation, subsequent cutting and use, and the third grade tiles are scrapped tiles.
[0049] In some embodiments, when the first water absorption rate is 0.1% to 0.13%, it is necessary to take another tile from the kiln position with the lowest temperature in the same batch as the second tile sample, and the second tile sample needs to be subjected to a second cutting process, a second grinding process, a second drying process, and a second soaking process in sequence to obtain a second water absorption rate.
[0050] In some embodiments, the second tile sample has a second preset size, and the second preset size is equal to the first preset size.
[0051] In some embodiments, the specific operation process of the second cutting process is the same as the specific operation process of the first cutting process.
[0052] In some embodiments, the detection area of the second ceramic tile blank includes: a first detection area, a second detection area, a third detection area, a fourth detection area and a fifth detection area. The first detection area is located on the central axis of the second ceramic tile blank. The second detection area is located on one side of the first detection area. The third detection area is located on the side of the first detection area away from the second detection area, and the third detection area is arranged opposite to the second detection area. The fourth detection area is located on the side of the first detection area close to the second detection area, and the fourth detection area is arranged opposite to the second detection area. The fifth detection area is located on the side of the first detection area close to the third detection area, and the fifth detection area is arranged opposite to the third detection area.
[0053] In some embodiments, the detection area of the second ceramic tile blank is the central axis and four corners of the second ceramic tile blank, so as to obtain 5 second water absorption rates.
[0054] In some embodiments, the sizes of the first detection zone, the second detection zone, the third detection zone, the fourth detection zone, and the fifth detection zone are all equal.
[0055] In some embodiments, the specific operation process of the second polishing process is the same as the specific operation process of the first polishing process. The specific operation process of the second drying process is the same as the specific operation process of the first drying process. The specific operation process of the second immersion process is the same as the specific operation process of the first immersion process.
[0056] In some embodiments, the second water absorption rate is calculated in the same manner as the first water absorption rate.
[0057] In some embodiments, the risk of tile cutting cracking is positively correlated with the magnitude of the second water absorption rate. When the second water absorption rate of any of the first detection area, the second detection area, the third detection area, the fourth detection area, and the fifth detection area is greater than 0.13%, the third level of the tiles of the current batch is determined. When the second water absorption rates of the first detection area, the second detection area, the third detection area, the fourth detection area, and the fifth detection area are all between 0.1% and 0.13%, the second level of the tiles of the current batch is determined.
[0058] The method for sorting tiles in the present application can sort tiles of different batches into the first grade, the second grade and the third grade according to the water absorption rate by obtaining the first water absorption rate and the second water absorption rate of different tiles of the same batch. As the key factor affecting the cracking of tiles during cutting and use, the water absorption rate can be used as a parameter for determining the quality grade of tiles. On the one hand, the first water absorption rate and the second water absorption rate provide a reference for adjusting the firing temperature of tiles, so as to effectively control the water absorption rate of tiles, thereby improving the quality of tiles and effectively alleviating quality problems such as cracking of tiles. On the other hand, the first water absorption rate and the second water absorption rate can provide a reference for sorting tiles according to quality grade, so as to facilitate the corresponding treatment of tiles of different quality grades.
[0059] In order to better illustrate the accuracy of the quality reference provided by the tile inspection method involved in this embodiment for tile inspection, the following example verification experiment is conducted:
[0060] Experimental group 1: In the process of producing 1000 square meters of 600mm*1200mm antique tiles, the tiles on the kiln with the lowest temperature are taken as the first tiles.
[0061] Experimental Group 2: In the process of producing 1200 square meters of 600mm*1200mm antique tiles, the tiles on the kiln with the lowest temperature were taken as the second tiles.
[0062] According to the above-mentioned tile inspection method, the water absorption rates of the first tile and the second tile are respectively obtained, and a comparison table of water absorption rates and cutting surface cracks of the experimental group 1 and the experimental group 2 is obtained as shown in Table 2.
[0063] Table 2 Comparison of water absorption and cut surface cracks
[0064]
[0065] Since it is difficult to ensure that the experimental conditions are completely consistent, there are certain errors in the above experimental data, but it does not affect the final experimental results. It can be seen from Table 2 that the first water absorption rate of the first ceramic tile in experimental group one is less than 0.1%, and there is no crack when it is cut, while the first water absorption rate of the first ceramic tile in experimental group two is between 0.1% and 0.13%, and 4 of the 5 second water absorption rates are greater than 0.13%, and the cutting cracks are relatively large. It can be seen that the ceramic tile sorting method provided in the present application can provide a reference basis for the cutting cracks generated in the subsequent cutting process of the ceramic tile by detecting the water absorption rate of the ceramic tile, and can provide a reference basis for the sorting of ceramic tiles according to quality grades.
