Embodiment Construction
[0026] Below in conjunction with embodiment the present invention will be further described:
[0027] 1. The production method of the attapulgite ceramic slurry is: (1) input the ingredients of the attapulgite ceramic slurry into a pulverizer for pulverization after mixing, and the particle fineness of the pulverized mixture is less than 0.25 mm; (2) the pulverized The mixture is added into the immersion pool for soaking and sodium treatment to form a wet mixture, and the soaking and sodium treatment time is controlled within 3 days; (3) The wet mixture is input into a pair of rollers and pressed into a sheet, the thickness of the sheet is less than 3 mm; (4) the sheet is input into the extruder to be extruded into a cylindrical strip, and the diameter of the cylindrical strip is controlled at 4 mm; (5) the cylindrical strip is input to the cement drying yard for drying Drying, the water content of the cylindrical strips after drying is less than 15%; (6) Input the cylindrical...

Abstract
The invention discloses a method for producing attapulgite ceramic slurry. The key point of the technical scheme is that: the method comprises the following steps of: mixing ingredients of the attapulgite ceramic slurry, grinding, soaking the ground mixture in water, performing sodium treatment to obtain a wet mixture, pressing the wet mixture into a sheet, extruding into a strip, airing, pulverizing, and deironing powder to obtain a semi-finished product; and putting the semi-finished product into a vacuum stirrer, adding water, and stirring to obtain slurry, namely the finished product of the attapulgite ceramic slurry. The attapulgite ceramic slurry consists of attapulgite clay, white bentonite, calcined clay, sodium humate and sodium carbonate. The attapulgite ceramic slurry produced by the method has high caking property, plasticity, fluidity, thixotropy, suspension property, stability, water content and permeability; a ceramic product prepared from the attapulgite ceramic slurryhas the characteristics of low shrinkage, no deformation, high strength and uniform texture; the method for producing the attapulgite ceramic slurry is simple, and low in cost; and the attapulgite ceramic slurry is suitable for forming and producing the ceramic product by a grouting method.
Description
technical field [0001] The invention relates to ceramic slurry, in particular to a production method of attapulgite ceramic slurry. 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-use porcel...
