Problems solved by technology

[0002] With the advancement of science and technology, the requirements for bentonite are getting higher and higher. my country's calcium-based bentonite is rich in resources and has large reserves, but its performance is poor and its quality is unstable. The physical and chemical properties of sodium-based bentonite are better than calcium-based bentonite. However, the reserves are small and the price is high, so it is necessary to artificially sodiumize the calcareous bentonite to transform it into bentonite with the physical and chemical properties of sodium soil

Abstract

The invention provides artificial sodium bentonite, comprising the following substances in parts by mass: 100 parts of bentonite, 3-10 parts of sodium modifier, 0.5-2 parts of synergist and 1-3 parts of tackifier, wherein the sodium modifier is a sodium salt. By adopting the artificial sodium bentonite provided by the invention, non-sodium bentonite, especially calcium bentonite can be effectively remodeled into sodium bentonite, so that the overall physical and chemical properties of the bentonite are improved to compensate the deficiency of the sodium bentonite storage amount, and the requirements of the society are met.

Description

technical field [0001] The invention relates to a bentonite, in particular to an artificial sodium bentonite. Background technique [0002] With the advancement of science and technology, the requirements for bentonite are getting higher and higher. my country's calcium-based bentonite is rich in resources and has large reserves, but its performance is poor and its quality is unstable. The physical and chemical properties of sodium-based bentonite are better than calcium-based bentonite. However, the reserves are small and the price is high, so it is necessary to artificially sodiumize the calcareous bentonite to transform it into bentonite with the physical and chemical properties of sodium soil. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a kind of artificial sodium bentonite, by adding sodium modifier, synergist and tackifier, to improve bentonite and improve the physical and chemical properties of b...
