Abstract

The invention discloses a one-time firing ultra-large-sized thin porcelain plate and a production method thereof, comprising the following steps: A. preparing a body powder for an ultra-large-sized thin porcelain plate according to a conventional method; B. preparing a super-large-sized porcelain plate according to a conventional method Bottom glaze and polishing glaze for thin porcelain plates; C, green body powder cloth and mold-free pressing; D, automatic green body cutting; E, green body drying; F, baking; G, super large size thin porcelain application Base glaze for porcelain plates; H, drying again; I, inkjet printing; J, applying polishing glaze for ultra-large and thin porcelain plates; K, drying for the third time; L, firing; M, edging. The beneficial effect of the present invention is to provide a one-time fired ultra-large thin porcelain plate and its production method, which solves the problem that the traditional thin porcelain plate is easy to be damaged and the blank body is damaged after the traditional thin porcelain plate adopts a water-containing decoration process such as wet glaze. Defects such as "water ripples", "frames" and "glaze curtain pull lines" that appear after glazing on the body surface, and expand the decoration methods of super-large and thin porcelain plates, which are not only suitable for waterless decoration processes, but also well The application of water-containing decoration technology significantly enriches the decoration style of super-sized thin porcelain plates and improves the decoration effect.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a one-time firing ultra-large and thin porcelain plate and a production method thereof. Background technique [0002] Affected by long-term geological movement and climate change, natural stone is mixed with associated minerals of other colors, forming a high-end, natural and rich decorative effect. As a high-end decorative material, it is favored by people. However, the associated radioactive minerals in some natural stones will cause radioactive hazards to human health; natural stones that have been affected by geological processes and weathering have many defects such as impurities and cracks, which are prone to "pathological changes" and poor performance. In addition, natural stone, as a non-renewable resource, is expensive and difficult to enter the homes of ordinary people; excessive mining and processing of natural stone not only causes the exhaustion of rare and...
