Description

Technical Field

[0001] The invention belongs to the technical field of marble processing, and in particular relates to a manufacturing process for imitating the surface feel of natural marble. Background Art

[0002] With the continuous development of the ceramic industry and consumers' increasing requirements for home decoration tiles, the surface effects of tiles have entered a high development period, gradually developing from the original simplest crystal glaze to a series of tiles with different effects such as bright full-polished glaze, soft glaze, antique dry grain surface, etc. Among them, natural marble is deeply favored by high-end home decoration for its unique texture and delicate and soft surface texture, but because natural marble is non-renewable and expensive to manufacture, its scope of use is greatly limited.

[0003] Especially when glazing imitation natural marble, due to the presence of methyl in the glaze, after mixing with the powdered base material, the viscosity will increase during the ball milling process. When the slurry and glaze flow rate cannot be adjusted according to the viscosity, bubbles are easily generated after the glaze impact is too large, which easily causes water vapor to condense at the bottom of the bell cover during glazing, resulting in a concave glaze feeling on the surface of the tile, an uneven glaze surface in some areas, and a wavy pattern, making it impossible to determine the molding quality. To this end, we propose a manufacturing process that imitates the surface of natural marble. Summary of the invention

[0004] The invention provides a manufacturing process for imitating the surface feeling of natural marble, which is used to solve the problems raised in the background technology.

[0015] A further improvement of the present invention is that the glaze stirring and output module includes a shower-coated flow-guiding bell assembly and a pre-loaded stirring and discharging mechanism, the pre-loaded stirring and discharging mechanism is installed at the top of the shower-coated flow-guiding bell assembly, and the output end of the quantitative glaze supply pipeline module is connected to the pre-loaded stirring and discharging mechanism.

[0016] A further improvement of the present invention is that the glaze-missing flow surface monitoring module of the diversion terminal includes a guiding arc surface low point flow velocity detection end, a supplementary surface adjustment and debugging unit and a missing surface facing diversion unit. The guiding arc surface low point flow velocity detection end is installed in a ring-shaped distribution on the outside of the pouring and diversion bell cover assembly, and is used to monitor the flow coverage area and flow velocity when the pouring and diversion bell cover assembly diverts the glaze. The missing surface facing diversion unit is installed on the transmission end of the supplementary surface adjustment and debugging unit, and the missing surface facing diversion unit diversion position is adjusted to the corresponding glaze-missing point pouring surface through the supplementary surface adjustment and debugging unit.

[0020] Compared with the prior art, the present invention reduces the high-temperature viscosity of the glaze and the bubbles in the glaze layer by adding white corundum, frit and calcium-magnesium-zinc-barium co-solvents into the glaze during the glazing process, thereby increasing the transparency and hardness of the glaze while ensuring anti-fouling. At the same time, the surface coating mechanism group can monitor the glaze flow rate and the missing surface analysis and supplement data, and timely supplement the glaze-missing point glazing surface. At the same time, the parallel contact surface of the brick body when it is immersed in the glazing point is corrected by the setting of the feed end plane calibration module and the horizontal feed correction module, thereby ensuring that the glaze is evenly sprinkled on the surface of the tile, avoiding the formation of water droplets at the bottom of the bell cover due to condensation of water vapor, resulting in a concave glaze feeling on the surface of the tile, thereby ensuring the flatness of the glazed surface, and making the tile feel more delicate and soft after glazing.

In order to better illustrate the specific embodiments of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-Figure 5 A manufacturing process for imitating the surface feel of natural marble, comprising the following steps: Step S1, powder selection: selecting ultrafine dry particles and fine sub-dry particles to make powder, and sieving it into 0.4-0.7g / ml base material.

[0030] Step S2, selecting a basic glaze: white corundum, frit, zinc oxide, strontium carbonate, barium carbonate, aluminum oxide, and a solvent are mixed in proportion, and the residue on the sieve is 1.59-1.72 g / ml as the basic glaze;

[0031] Step S3, mixing the glaze material: remixing the powder obtained in step S1 and the basic glaze obtained in step S2 to obtain the glaze material;

[0032] Step S4, glazing; the glaze material obtained in step S3 is evenly poured on the surface of the tile through the surface coating mechanism group;

[0033] Step S5, post-firing treatment of the brick body: sending the ceramic tile into the kiln for firing, the firing temperature is 1150-1190°C, the firing cycle is at least 70min-75min, and after cooling, the surface of the ceramic tile is polished to control the glossiness of the ceramic tile;

[0034] Among them, 5.2-8% white corundum, 25.8-30% frit, 12-20% talc, 3%-5% zinc oxide, 5%-10% strontium carbonate, 5%-10% barium carbonate, 5%-10% aluminum oxide, and 8-10% solvent.

[0035] Wherein, the glossiness of the thorn-turned surface after the polishing treatment in step S4 is controlled at 30±5 degrees.

[0036] The ultrafine dry particle size selected in step S1 is D50=20 μm.

[0037] In this embodiment, the frit is partially replaced by wollastonite and feldspar, and the talc is replaced by diopside or dolomite + quartz to reduce the cost of glazing. The addition of white corundum, frit and calcium magnesium zinc barium solvents to the glaze is intended to reduce the high temperature viscosity of the glaze, facilitate exhaust, reduce bubbles in the glaze layer, and increase the transparency and hardness of the glaze while ensuring the anti-fouling requirements, and improve the wear resistance and leveling properties.

[0038] The surface-sensing coating mechanism group includes a glaze-deficient circulation surface monitoring module 2 at the diversion terminal, a glaze curtain missing surface adaptation and supplementation module 3, an intermittent glaze-deficient amount supplementation control module 4, a coating transmission belt speed control module 5 and a quantitative glaze supply pipeline module 6. The quantitative glaze supply pipeline module 6 is used to guide the glaze material to the glaze mixing output module 1 at a preset flow rate. The coating transmission belt speed control module 5 is used to transport the glaze material to the bottom of the glaze mixing output module 1 at equal intervals. The glaze-deficient circulation surface monitoring module 2 at the diversion terminal is used to monitor the discontinuity of the glaze curtain when the glaze mixing output module 1 guides the glaze material. The intermittent glaze-deficient amount supplementation control module 4 analyzes the corresponding glaze filling amount after reading the monitoring data of the glaze-deficient circulation surface monitoring module 2 at the diversion terminal, and sends a control signal to the glaze curtain missing surface adaptation and supplementation module 3, and supplements the local coating amount through the missing surface supplementation output terminal 31 corresponding to the glaze-deficient point pouring surface.

[0039] In this embodiment, the pouring and diversion bell cover assembly 11 diverts the glaze material through the bell cover surface, so that the pouring glaze material flows onto the surface of the ceramic tile. At the same time, when the pouring glaze material flows to its lower end position on the bell cover surface of the pouring and diversion bell cover assembly 11, the flow velocity of the glaze curtain when the glaze mixing output module 1 diverts the pouring glaze material is monitored by the diversion terminal glaze lacking flow surface monitoring module 2, and whether the glaze curtain is discontinued due to the influence of local flow velocity. When the glaze curtain is discontinued, that is, the glaze curtain missing surface adaptation supplement module 3 monitors the data and analyzes the corresponding glaze filling amount, and sends a control signal to the missing surface filling output terminal 31, so that the local pouring coverage amount is supplemented by the missing surface filling output terminal 31 corresponding to the pouring surface of the missing glaze point.

[0040] The glaze mixing and output module 1 includes a coating and diversion bell assembly 11 and a pre-loaded stirring and discharging mechanism 12. The pre-loaded stirring and discharging mechanism 12 is installed at the top of the coating and diversion bell assembly 11, and the output end of the quantitative glaze supply pipeline module 6 is connected to the pre-loaded stirring and discharging mechanism 12.

[0041] In this embodiment, the glaze material obtained in step S3 is transported to the glazing area through the quantitative glaze supply pipeline module 6. After the quantitative glaze supply pipeline module 6 presets the glaze material supply flow rate, the glaze material is guided to the pre-loaded stirring and discharging mechanism 12 at the preset flow rate. The transported glaze material is stirred by the pre-loaded stirring and discharging mechanism 12 to ensure that the conduction speed when flowing to the glazing guide bell cover assembly 11 is normal.

[0042] The diversion terminal glaze-deficient flow surface monitoring module 2 includes a guiding arc surface low point flow velocity detection end 21, a supplementary surface adjustment and debugging unit 22 and a missing surface facing flow guide unit 23. The guiding arc surface low point flow velocity detection end 21 is installed in a ring-shaped distribution on the outside of the pouring and diversion bell cover assembly 11, and is used to monitor the flow coverage area and flow velocity when the pouring and diversion bell cover assembly 11 diverts the glaze. The missing surface facing flow guide unit 23 is installed on the transmission end of the supplementary surface adjustment and debugging unit 22, and the missing surface facing flow guide unit 23 is adjusted to the corresponding glaze-deficient point pouring surface through the supplementary surface adjustment and debugging unit 22.

[0043] In this embodiment, the guiding arc surface low point flow rate detection end 21 installed in an annular shape on the outside of the pouring and diversion bell cover assembly 11 is used as a monitoring end for the flow rate of the glaze curtain when the pouring and diversion bell cover assembly 11 is diverting, and whether the glaze curtain is discontinuous due to the influence of local flow rate. The supplementary surface mobilization debugging unit 22 is used to guide the arc surface low point flow rate detection end 21 to obtain the partial loss of the glaze curtain or the flow rate cannot meet the uniform glazing requirement, and control the missing surface to be transmitted to the corresponding glaze missing point pouring surface toward the guide unit 23, and then the glaze filling output end of the missing surface filling output end 31 is directly aligned with the partial loss position of the glaze curtain monitored by the guiding arc surface low point flow rate detection end 21, so as to achieve the effect of balanced supplementation, and then ensure that the glaze is evenly poured on the surface of the tile, avoid the formation of water droplets due to condensation of water vapor at the bottom of the bell cover, and cause the surface of the tile to have a concave glaze feeling, and then ensure the flatness of the glazed surface, so that the tile feels more delicate and soft after glazing.

[0044] A feed end plane calibration module 7 is installed on one side of the glaze mixing and output module 1. The feed end plane calibration module 7 includes an initial end feed detection end 71, a measuring surface segmentation unit 72, a brick body overfeed transmission unit 73 and an overfeed parallel distribution surface detection unit 74. The initial end feed detection end 71 is installed at one end of the coating transmission belt speed control module 5, the measuring surface segmentation unit 72 is installed on the inner side of the initial end feed detection end 71, the measuring surface segmentation unit 72 is used to divide the detection coverage surface of the initial end feed detection end 71 into a plurality of detection points, the brick body overfeed transmission unit 73 is rotatably connected to the measuring surface segmentation unit 72, the overfeed parallel distribution surface detection unit 74 is sleeved on the outer side of the brick body overfeed transmission unit 73, and the overfeed parallel distribution surface detection unit 74 is used to reflect the parallelism of the conveying end surface when the brick material is glazed and conveyed.

[0045] In this embodiment, when the monitoring end of the intermittent glaze deficiency supplement control module 4 obtains the loss of the glaze surface, the coating transmission belt speed control module 5 controls the starting speed of the transmission belt to decrease. When the brick body is transported to the position below the initial end feeding detection end 71, the multiple parallel surface detection points of the segmented measuring surface segmentation unit 72 cover the top surface of the brick body, and the parallel accuracy of the current brick body transportation process is obtained by contacting the surface of the brick body when the over-feed parallel distribution surface detection unit 74 located at each segment detection point contacts the surface of the brick body when it is transported forward. The brick body over-feed transmission unit 73 plays a transmission guiding role when the over-feed parallel distribution surface detection unit 74 contacts the brick body, and can maintain the contact surface between the over-feed parallel distribution surface detection unit 74 and the brick body. Through the rotational displacement transmission of the brick body over-feed transmission unit 73, the transmission restriction of the brick body due to excessive fitting can be avoided, ensuring that the over-feed parallel distribution surface detection unit 74 stably obtains the parallelism data of the brick body when it is fed into the glazing end, which is used as a correction processing parameter.

[0046] The feeding end plane calibration module 7 is installed with a horizontal feeding correction module 8 and a control command processing end 9. The horizontal feeding correction module 8 includes a debugging dynamic execution unit 81, a point parallel pressure applying unit 82 and a parallel feedback unit 83. The parallel feedback unit 83 is installed at the output end of the point parallel pressure applying unit 82. The point parallel pressure applying unit 82 is connected to the debugging dynamic execution unit 81 by signal. The control command processing end 9 is used to send the parallelism detection data reflected by the parallel distribution surface detection unit 74 to the debugging dynamic execution unit 81. The debugging dynamic execution unit 81 transmits the corresponding debugging command to the point parallel pressure applying unit 82, and controls the parallel feedback unit 83 through the point parallel pressure applying unit 82 to change the parallel surface of the contact end when the brick is glazed;

[0047] In this embodiment, after the control command processing end 9 obtains the parallelism data of the brick body when it is fed into the glazing end measured by the parallel distribution surface detection unit 74, it sends a corresponding control execution signal to the debugging dynamic execution unit 81, and corrects the guidance angle according to the parallelism deviation value through the point parallel pressure application unit 82, so that after the brick body end reaches the position of the parallel feedback unit 83, the parallel glazing surface is adjusted through the correction guidance of the parallel feedback unit 83. After the parallel feedback unit 83 senses that the conveying parallelism of the brick body during glazing conveying remains stable, the glazing operation continues to ensure the smoothness of the glazed surface.

[0049] See also Figure 1-Figure 2 A manufacturing process for imitating the surface feel of natural marble, comprising the following steps: Step S1, powder selection: selecting ultrafine dry particles and fine sub-dry particles to make powder, and sieving it into 0.4-0.7g / ml base material.

[0050] Step S2, selecting a basic glaze: white corundum, frit, zinc oxide, strontium carbonate, barium carbonate, aluminum oxide, and a solvent are mixed in proportion, and the residue on the sieve is 1.59-1.72 g / ml as the basic glaze;

[0051] Step S3, mixing the glaze material: remixing the powder obtained in step S1 and the basic glaze obtained in step S2 to obtain the glaze material;

[0052] Step S4, glazing; the glaze material obtained in step S3 is evenly poured on the surface of the tile through the surface coating mechanism group;

[0053] Step S5, post-firing treatment of the brick body: sending the ceramic tile into the kiln for firing, the firing temperature is 1150-1190°C, the firing cycle is at least 70min-75min, and after cooling, the surface of the ceramic tile is polished to control the glossiness of the ceramic tile;

[0054] Among them, 5.2-8% white corundum, 25.8-30% frit, 12-20% talc, 3%-5% zinc oxide, 5%-10% strontium carbonate, 5%-10% barium carbonate, 5%-10% aluminum oxide, and 8-10% solvent.

[0055] The intermittent glaze deficiency replenishment control module 4 includes an arc surface flow velocity database 41, a passive flow velocity data reading unit 42, an intermittent flow velocity variable verification unit 43 and a supplementary signal generation unit 44. The arc surface flow velocity database 41 is used to record the glaze flow and stirring speed during normal glazing. The passive flow velocity data reading unit 42 is used to read the glaze supply speed of the quantitative glaze supply pipeline module 6, the stirring speed of the glaze by the pouring and guiding bell cover assembly 11, and the glaze flow rate and missing surface monitored by the guiding arc surface low point flow velocity detection end 21. The intermittent flow velocity variable verification unit 43 is used to compare the arc surface flow velocity database 41 and the passive flow velocity data reading unit 42 to obtain the data difference, and then generate the corresponding supplementary data through the supplementary signal generation unit 44.

[0056] In this embodiment, in order to further ensure that the glaze is evenly poured on the surface of the tile, the glaze flow and stirring speed during normal glazing are recorded through the arc surface flow velocity database 41, and the passive flow velocity data reading unit 42 reads the glaze supply speed of the quantitative glaze supply pipeline module 6, the flow speed of the current glaze curtain monitored by the guiding arc surface low point flow velocity detection end 21, the stirring speed of the stirring mechanism in the pre-loaded stirring and discharging mechanism 12, and the conveying residence time of the tile by the coating transmission belt speed control module 5 respectively. The intermittent flow velocity variable verification unit 43 is used to compare the difference between the arc surface flow velocity database 41 and the passive flow velocity data reading unit 42 to obtain the corresponding auxiliary glaze supply debugging parameters, that is, the control command is produced by the supplementary signal generation unit 44, and the corresponding quantitative supply The glaze supply end output speed of the glaze pipeline module 6 and the stirring speed of the pre-loaded stirring and discharging mechanism 12 are correspondingly debugged, and then the current glaze curtain flow rate is monitored again through the guiding arc surface low point flow rate detection end 21 to see whether it is consistent with the normal data entered in the arc surface flow rate database 41, and whether the glaze curtain guided by the sprinkling and diversion bell cover assembly 11 is missing. If the glaze curtain is still true, the corresponding supplementary flow is generated according to the current flow rate through the missing surface filling output end 31, and the missing surface is adjusted through the supplementary surface. The debugging unit 22 adjusts the diversion position of the guide unit 23 to debug the corresponding glaze-missing point sprinkling surface, and the glaze is output through the missing surface filling output end 31 for local glaze supplement, and the sprinkling and covering transmission belt speed control module 5 is debugged according to the missing surface. The interval residence time of the tiles arriving at the bottom of the sprinkling and covering diversion bell cover assembly 11 during transmission ensures that the glaze is fully and evenly coated on the tile surface.
