Ceramic Plate Roller-Printed Glaze for Iridescent Cloud Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceramic plate production technologies limit the surface decoration effect, with most products having simple, monotonous designs due to the use of inkjet printing and polished or dry granular surfaces.
Innovation Solution
A ceramic plate with a colorful flowing cloud surface decoration effect is achieved by applying a brightly colored cover glaze, roller-printing patterns, and spraying a metallic liquid luster, utilizing a high-silicon cover glaze and roller effect glaze with specific chemical compositions to create a vivid, iridescent effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If inkjet printing technology is used for surface decoration, then the production process is simple and easy to implement, but the decoration effect is limited and monotonous
Solution Approach 1:
The patent changes the chemical composition parameters of the glaze by adding specific metal oxides (0.2-0.7 wt% coloring metal oxide, 7-8 wt% TiO2, 9-11 wt% ZnO) to create flowing cloud effects and iridescent effects that cannot be achieved with conventional inkjet printing, thereby improving decoration effect quality while maintaining production process simplicity
Solution Approach 2:
The patent uses composite glaze materials combining multiple components (silica, alumina, calcium oxide, magnesium oxide, potassium oxide, zinc oxide, and coloring metal oxides) to achieve complex decorative effects including flowing cloud patterns and iridescence, resolving the contradiction between manufacturing simplicity and decoration quality
2Shape
If polished ceramic products are produced, then the surface is smooth and glossy, but the decoration effect is simple and lacks variety
Solution Approach 1:
The patent applies different glaze compositions to different areas or layers: a ground glaze layer for base coverage and a cover glaze layer with specific metal oxide content (0.2-0.7 wt%) for colorful flowing cloud effects, allowing both surface smoothness and decorative complexity to coexist
Solution Approach 2:
The patent adds a temporal dimension to the decoration by creating iridescent effects that change appearance under different light conditions, and a textural dimension through flowing cloud patterns, transforming the decoration from simple polished surfaces to multi-dimensional visual experiences
3Quantity of substance
If traditional iridescent effects are created by light refraction or reflection, then the effect is achieved without additional materials, but the effect is limited and not colorful enough
Solution Approach 1:
The patent introduces coloring metal oxides (0.2-0.7 wt%) including copper oxide, cobalt oxide, nickel oxide, and manganese oxide into the glaze composition to create vibrant, colorful iridescent effects that exceed the limitations of traditional light refraction methods, directly enhancing colorfulness and effect intensity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method produces a ceramic plate with a strong, three-dimensional, iridescent flowing cloud effect, offering good decoration, easy cleaning, wide application, high durability, and resistance to environmental factors.
Implementation Method 1
utilizes a metallic liquid luster (coloring liquid luster) to attach coloring metals to the surface of the ceramic plate to form an iridescent effect under light irradiation
Implementation Method 2
different from traditional iridescent effects (the phenomenon of color light generated by refraction or reflection of light directly into the medium)
Implementation Method 3
drying the green body after roller-printing the pattern and firing in a kiln

AI summary
A preparation method includes: pressing and forming a ceramic base material to obtain a green body of a ceramic plate; applying a ground glaze on the surface of the green body to cover the base color and defects of the green body; applying a cover glaze on the surface of the green body after applying the ground glaze, wherein the cover glaze contains 0.2 wt % to 0.7 wt % of coloring metal oxide to make the coloring bright; roller-printing patterns on the surface of the green body after applying the cover glaze to produce a flowing cloud effect; and drying the green body with the roller-printed patterns and firing in a kiln. The present invention uses roller printing to print the patterns of cloud effect on the surface of the cover glaze, which form a sharp contrast with the color of the cover glaze, producing a better visually distinct effect.
