Acidified attapulgite clay

Abstract

The invention discloses acidified attapulgite clay, and the key points of the technical scheme are that: the acidified attapulgite clay comprises the ingredients of attapulgite clay, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. A production method of the acidified attapulgite clay is as follows: acidified attapulgite clay ingredients are transported into a mill for milling powder, and the milled powder is the acidified attapulgite clay. Acidification treatment can remove impurities distributed in attapulgite clay pore channels, the pore channels are dredged, and the pore volume is increased. The acidified attapulgite clay can improve the adsorption property, decolorization rate, catalytic action, specific surface area and porosity of the attapulgite clay, colloid viscosity of the acidified attapulgite clay can be increased and the PH of the acidified attapulgite clay can be adjusted. The acidified attapulgite clay is applicable to the production of products of petroleum, chemical industry, medicines, building materials, plastics and other industry fields.

Description

technical field [0001] The invention relates to acidification treatment, in particular to acidified attapulgite clay. Background technique [0002] In addition to attapulgite clay, attapulgite clay also contains minerals such as bentonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. In order to improve the related properties of attapulgite clay, it is necessary to Acidification treatment of stone clay. [0003] In the attapulgite clay mining area, the attapulgite clay ore is mechanized mined by excavators. What is excavated is a dense massive attapulgite clay ore. The attapulgite clay ore is relatively large and cannot be directly used for acidification treatment. , often using a pulverizer to break into fine particles for acidification, which can easily destroy the crystal structure of attapulgite. [0004] Although the adsorption performance of attapulgite clay can be improved after acidification, the colloidal performance of attapulgite clay is greatly ...

AI Technical Summary

Problems solved by technology

[0004] After the acidification of attapulgite clay, although the adsorption performance can be improved somewhat, the colloidal performance of attapulgite clay is greatly reduced, and it cannot be directly used to produce molecular sieves, catalysts and desiccants that require a certain colloidal viscosity.
