Problems solved by technology

[0005] The ceramic pressing method requires low moisture content of the green body, compact green body, small drying shrinkage, accurate shape and size of the product, large production capacity, and is convenient for large-scale mechanized production. However, the moisture content of the green body of some newly developed china clay raw materials is unstable. , shrinks greatly after drying, and is prone to cracks, which directly affects the quality of ceramic products

Abstract

The invention discloses a method for producing an attapulgite ceramic pressing process forming blank, which is technically characterized by comprising the steps of: mixing ingredients of the attapulgite ceramic pressing process forming blank and then crushing, adding the crushed mixture in a soaking tank for soaking with water and carrying out sodium treatment, pressing the mixture subjected to soaking and sodium treatment into a sheet, extruding the sheet into a strip, airing and then grinding, removing iron from powder, inputting the powder in a stirrer, adding water for stirring, and uniformly stirring to form a finished product of the attapulgite ceramic pressing process forming blank. The attapulgite ceramic pressing process forming blank comprises attapulgite clay, white bentonite, kaolin, calcined clay, sodium metasilicate and sodium carbonate. The attapulgite ceramic pressing process forming blank has low water content and is compact, has the advantages of better caking property, plasticity, high yield value and large extension deformation, and is suitable for forming and producing ceramic products by adopting a pressing process.

Description

technical field [0001] The invention relates to a ceramic blank, in particular to a production method for a blank formed by an attapulgite ceramic pressing method. [0002] Law. Background technique [0003] The composition of China clay is mainly kaolin, and contains feldspar, quartz stone, mica, iron ore and other rock fragments as the source of China clay. China clay is the main raw material of ceramics. The development of high-grade daily-use porcelain requires high-quality kaolin as raw material. With the rapid development of the domestic ceramic industry in 2009, the consumption of kaolin has also increased sharply. However, with the depletion of high-quality kaolin veins, the price of china clay has skyrocketed day by day. [0004] On the premise of ensuring the quality of china clay, develop new china clay raw materials to replace kaolin or reduce the amount of kaolin to protect our ecological environment and provide more sufficient raw material guarantee for the fu...
