Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of mud glaze layer preparation, and specifically relates to a mud glaze layer intelligent carving method. Background Art
[0002] Glaze (glazing decoration) has always been the focus of technology and product innovation in the ceramic tile industry. In the current production and manufacturing of ceramic tiles, the glazing line is generally used as a conveyor, and the glaze decoration is completed during the operation of the glazing line. So far, although many decorative process methods have been formed, they are generally "additive process" articles on the surface of the basic glaze (bottom glaze, top glaze) of the ceramic tile blank, including spot glaze, cloud glaze, dry glaze (glaze powder), etc., and then combined with screen printing, roller printing or inkjet printing to give texture patterns.
[0003] This kind of glaze "additive process" thinking has always been limited to traditional thinking, and the decorative innovation effect is naturally limited. The decorative technology in other material fields has made progress that breaks through traditional thinking. For this reason, the goal is to do "subtractive process" on the basic glaze of the body. Traditional concave-convex glaze generally has the following processes. The first is to use a concave-convex mold to form a concave-convex texture on the surface of the body, and then apply glaze to obtain a concave-convex glaze; the second is to use screen or roller printing to form a concave-convex glaze on the basic glaze; the third is to use dry glazing (dry particles) to print concave-convex patterns (surface glaze) according to the shape of the texture; the fourth is to use a boundary agent or corrosion glaze to form a concave-convex texture pattern using the tension of the glaze. However, no matter which traditional process method is used, it is all about "additive process". Its characteristics are generally that the concave-convex layer is very thin (generally ≤0.4mm), the texture is not fine and accurate enough, and the boundary is arc-shaped (pile angle ≤60o), the texture is rough and sparse, and the shape is simple, and the "3D high-pixel" stereoscopic effect cannot be obtained. Summary of the invention
[0004] The purpose of the present invention is to provide a method for intelligent carving of clay glaze layer, combining digital carving technology with glaze layer printing and decoration technology to achieve a "3D high-pixel" glaze layer with a three-dimensional texture, thereby obtaining a relief pattern with more realistic effects and richer materials.
[0005] In order to achieve the above object, the present invention provides the following technical solutions: A method for intelligently carving a clay glaze layer comprises the following steps: S1: sequentially preparing a biscuit, applying a base bottom glaze, and applying a base top glaze, wherein the thickness ratio of the three is 1:0.4-0.6:0.5-0.7; printing a concave-convex glaze layer by underglaze inkjet printing; wherein, when printing the concave-convex glaze layer, the glaze line conveying speed is controlled to be 3-8m / min, the printing speed is 50-100 sheets / h, the printing time is 30-45 seconds / sheet, the peak thickness is 1-2mm, and the average glaze amount is 900-1200g / m 2 ; S2: spray a protective film on the upper surface of the glaze layer obtained in step S1, and start intelligent carving of the glaze layer after online drying; when the glaze layer is intelligently carved, the glaze line conveying speed is controlled to be 3-8m / min, the carving speed is 80-120 pieces / h, the carving head tool holder running line speed is 7-10m / min, the tool holder stroke width is 1000-1300mm, the depth is 0-2mm, the carving accuracy horizontal error is ≤0.05mm, and the depth error is ≤0.01mm; then the glaze blank product is obtained after powder cleaning and online drying.
[0006] Furthermore, the process of preparing the green blank in step S1 is: by weight, 30-50 parts of the green blank and 4-8 parts of water are mixed evenly, ground by a ball mill through a 100-120 mesh sieve, and dried at 100-120° C. for 30-50 minutes to obtain the green blank.
[0007] Furthermore, the process of applying the base glaze in step S1 is as follows: by weight, 7-9 parts of limestone, 4-7 parts of barium carbonate, 1-3 parts of glass fiber and 4-10 parts of water are mixed evenly, and a laser power of 50-70w, a scanning speed of 400-600mm / s, a laser temperature of 1000-1100°C, and a scanning trajectory of "back and forth linear" scanning are used, and each layer is rotated 60-80°C to obtain the base glaze.
[0008] Furthermore, in step S1, 8 parts of limestone, 5 parts of barium carbonate, 2 parts of glass fiber and 8 parts of water are mixed evenly by weight, and a laser power of 65w, a scanning speed of 500mm / s, a laser temperature of 1035°C, and a scanning trajectory of "back and forth linear" scanning are used, and each layer is rotated 70° to obtain a basic base glaze.
[0009] Furthermore, the process of the basic glaze in step S1 is as follows: by weight, 10-12 parts of diatomaceous earth, 1-3 parts of silicon dioxide, 2-4 parts of attapulgite and 7-10 parts of water are mixed evenly, and a laser power of 65-75w, a scanning speed of 350-450mm / s, a laser temperature of 1200-1300℃, a scanning trajectory of linear scanning back and forth, and a rotation of 60-80℃ layer by layer are used to obtain the basic glaze.
[0010] Furthermore, in step S1, 11 parts of diatomaceous earth, 2 parts of silicon dioxide, 3 parts of attapulgite and 8 parts of water are mixed evenly by weight, and a laser power of 70w, a scanning speed of 400mm / s, a laser temperature of 1250°C, a scanning trajectory of linear scanning back and forth, and a rotation of 75° layer by layer are used to obtain a basic glaze.
[0011] Furthermore, in step S1, the glaze line conveying speed is controlled to be 6 m / min, the printing speed is 85 sheets / h, the printing time is: 36 seconds / sheet, the peak thickness is 1.6 mm, and the average glaze amount is 1100 g / m 2 .
[0012] Furthermore, the process parameters for spraying the protective film on the upper surface in step S2 are: liquid circuit pressure 0.35-0.45 bar, gas circuit pressure 1.6-2.4 bar, liquid circuit flow rate 6-7 L / h; the protective film is a PET protective film with a thickness of 0.1-0.13 mm.
[0013] Furthermore, in step S2, the temperature of the online drying is 100-130° C. and the time is 25-45 min.
[0014] Furthermore, in step S2, the glaze line conveying speed is controlled to be 5m / min, the engraving speed is 110 pieces / h, the engraving head tool holder running line speed is 8m / min, the tool holder stroke width is 1200mm, the depth is 1.6mm, the engraving accuracy horizontal error is ≤0.05mm, and the depth error is ≤0.01mm; then the glaze blank product is obtained after powder cleaning and online drying.
[0015] Compared with the prior art, the advantages and beneficial effects of the present invention are: 1. The present invention uses "glaze layer printing and molding" to first print a thick, accurately positioned, and richly textured concave-convex glaze layer pattern (additive process) on the basis of the base glaze and the top glaze, so that the surface obtains a concave-convex glaze layer according to the predetermined design shape, color, thickness, and positioning. However, since the printing molding material is in a slurry state, the printing point will instantly produce a tiny flow, and the glaze layer boundary will present a small heap angle or arc shape, and it is impossible to obtain a large heap angle (near vertical) boundary and a narrow deep groove effect. Then, the innovative "glaze layer intelligent engraving technology" (subtractive process) is used to accurately and precisely trim the texture, and the "engraving machine" is used to perform precise "minimally invasive surgery" on the glaze layer heap angle and groove depth to remove excess glaze, thereby further obtaining a "3D high-pixel" three-dimensional effect with clear boundaries, deep and straight grooves, high and low staggered, and rich shapes.
[0016] 2. Through the combination of "glaze layer printing molding technology" and "glaze layer intelligent carving technology", we finally successfully obtained a 3D high-pixel concave-convex glaze layer. The glaze surface has a realistic effect of mountains, gullies, peaks and cliffs, breaking through the limitations of traditional concave-convex glaze being shallow and smooth, and laying an important technical foundation for "3D high-pixel manufacturing.
