Abstract

The invention discloses a super-large-sized thin porcelain plate with anion function and a production method thereof, comprising the following steps: A. preparing super-large-sized thin porcelain body powder according to a conventional method; B. preparing a super-large porcelain plate according to a conventional method Base 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, thin porcelain application Base glaze for plates; H, re-drying; I, inkjet printing; J, applying polishing glaze for thin porcelain plates; K, third drying; L, firing; M, edging. The beneficial effect of the present invention is to provide a super-large-sized thin porcelain plate with negative ion function and its production method, which solves the problem that the traditional thin-shaped porcelain plate adopts wet glazing and other water-containing decoration processes. Defects such as damage, "water ripples", "frames", and "glaze curtain pull lines" that appear after glazing on the surface of the green body, and endow super-large-sized thin porcelain plates with negative ions, health and environmental protection functions.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to an ultra-large thin porcelain plate with negative ion function 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 ...
