AI Technical Summary

Technical Problem

Existing glue-based dry granule technology interferes with the color development of the underlying design, resulting in reduced color saturation. Incompatibility issues between glaze and glue/ink lead to glaze defects, making it difficult to achieve a harmonious presentation of large-area dark designs and three-dimensional textures.

Method used

The pretreatment method using digital adhesive dry granules includes pretreatment of the body, application of base glaze, spraying of digital positioning adhesive, application of dry granules, spraying of top glaze, and kiln firing. Modified nano-calcium carbonate agent is used to improve the compatibility of the glaze, ensuring that the dry granules are placed under the top glaze, and the designed colors are printed on the surface of the top glaze.

Benefits of technology

It achieves accurate presentation of large-area dark-colored design patterns, increases color saturation to 85%, reduces glaze defect rate to below 1%, improves product qualification rate to 98%, and maintains three-dimensional texture and warm touch.
