Production method for attapulgite ceramic plastic mass

Abstract

The invention discloses a production method for an attapulgite ceramic plastic mass. The key point of the technical scheme is that the production method comprises the following steps of: crushing ingredients of the attapulgite ceramic plastic mass, performing sodium treatment on the crushed mixture into a moist mixture, pressing the moist mixture into a sheet, extruding into a strip, airing the strip, grinding, removing iron from powder, adding water into the powder, extruding into a cylindrical strip, and packaging into the finished product of the attapulgite ceramic plastic mass. The attapulgite ceramic plastic mass consists of attapulgite clay, white bentonite, sepiolite, calcined clay, sodium metasilicate and sodium carbonate. The attapulgite ceramic plastic mass has uniform water content and consistent structure, and has the characteristics of good cohesiveness, plasticity, high yield value and large extension deformation; ceramic products prepared from the attapulgite ceramic plastic mass have the characteristics of small shrinkage, no deformation, high strength, and uniform texture; and the attapulgite ceramic plastic mass is suitable for producing the ceramic products.

Description

technical field [0001] The invention relates to a plastic blank, in particular to a production method of an attapulgite ceramic plastic blank. Background technique [0002] 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. [0003] 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 future development of high-grade daily...

Problems solved by technology

[0004] The main processes of plastic forming are spinning forming and rolling forming, which require uniform water content, consistent structure, good plasticity, high yield value and large elongation deformation of the billet, but some newly developed china clay raw materials have low yield value and elongation. The amount of deformation is small, which directly affects the quality of ceramic products
