AI Technical Summary

Problems solved by technology

The use of anti-type saggers has the following problems: 1. Flat products of different shapes and specifications must be equipped with special imitation saggers, which will inevitably increase the manufacturing cost of kiln furniture; 2. Reduce the utilization rate of the kiln. Increase fuel costs, resulting in waste of energy; 3. Increase the labor intensity of operators, reduce labor production efficiency, and poor working environment; 4. Seriously restrict the development timeliness of bone china varieties

Abstract

The present invention relates to a high-temperature biscuit fired bone porcelain production process having no copying kiln furniture. Said production process is implemented by regulating its formula and improving its technical process. Said invention provides its formula composition, and its technical process includes the following steps: raw material treatment, mixing materials, grinding, sieving to remove iron, press-filtering, kneading mud, forming, finishing blank, drying, high-temperature biscuit firing, sorting, glazing, glaze firing, checking and selecting and packaging.

Description

technical field [0001] The present invention relates to the invention and creation of the bone china production process, in particular to a non-imitation kiln furniture high-temperature biscuit-fired bone china production process and its formula. Background technique [0002] Bone China is a world-recognized high-grade daily-use porcelain, which originated in England in the 18th century. After more than 200 years of development, bone china has become one of the high-end daily-use porcelains popular all over the world because of its white porcelain, smooth and soft glaze, and good light transmittance. my country researched and trial-manufactured in the 1960s, trial-produced in the 1970s, and mass-produced in the 1980s. The output has expanded year by year, and the quality level has improved day by day. Since the 1990s, some domestic universities and scientific research institutes have conducted a lot of research on bone china microstructure characteristics, bone china formul...
