Problems solved by technology

[0003] In recent years, with the continuous expansion of Dehua's export of ceramics, the demand for ceramic raw materials has also increased. Dehua does not produce high-quality ceramic raw materials locally, and the price of domestic high-quality ceramic raw materials continues to rise, resulting in production costs. The increase and production scale are restricted, and the dependence on high-quality raw materials supplied from outside has become a bottleneck restricting the development of Dehua ceramic enterprises.

Abstract

The invention belongs to the field of ceramic production, and particularly relates to a formula and a production process for producing a high-quality porcelain by using poor quality raw materials such as weathered feldspar, porcelain sand, red soil and other poor-quality raw materials. According to the formula, the weathered feldspar, the black clay, the kaolin, the black talc and the porcelain clay produced in the Dehua are subjected to the production process with characteristics of reasonable formula and right control so as to produce the daily-use porcelain meeting the export standard, such that the bottleneck problem constraining the Dehua exported ceramic enterprise development is solved, the production cost is substantially reduced, the raw material supply time is shortened, the economic efficiency is improved, the market competitiveness of the exported ceramic enterprise is enhanced, and the great promotional value and the great social and economic benefits are provided.

Description

technical field [0001] The invention belongs to the field of ceramic manufacturing, and in particular relates to a formula and a manufacturing process for high-quality porcelain made of inferior raw materials such as weathered feldspar, porcelain sand, and laterite. Background technique [0002] Dehua has a long history of ceramic production, and is the birthplace of my country's ceramic culture and one of the three major ancient porcelain capitals. More than 80% of Dehua ceramic products are exported to more than 190 countries and regions. It is one of the top ten key export counties (cities) in Fujian Province. One, the country's largest production and export base of craft ceramics. [0003] In recent years, with the continuous expansion of the scale of Dehua's export of ceramics, the demand for ceramic raw materials has also increased. Dehua does not produce high-quality ceramic raw materials locally, and the price of domestic high-quality ceramic raw materials continues t...
