Bentonite inhales blue volume analysis testing arrangement

Technical Field

The utility model relates to a blue volume analysis and test technical field is inhaled to bentonite, concretely relates to blue volume analysis and test device is inhaled to bentonite.

Background

The bentonite is a non-metal mineral product with montmorillonite as a main mineral component, and the montmorillonite structure is 2: the crystal structure of the type 1 has better ion exchange performance because certain cations, such as Cu, Mg, Na, K and the like, exist in a layered structure formed by montmorillonite unit cells, and the cations have unstable effects with the montmorillonite unit cells and are easy to exchange with other cations. Foreign countries have been applied to more than 100 departments in 24 fields of industrial and agricultural production, and more than 300 products exist, so that the soil is called as 'universal soil'.

The blue absorption amount of the bentonite is the capability of absorbing methylene blue when the bentonite is dispersed in an aqueous solution, the absorbed amount is called blue absorption amount, the higher the montmorillonite content in the bentonite is, the more the absorbed amount is, and the blue absorption amount can be used as a main technical index for roughly estimating the relative content of the montmorillonite in the bentonite ore.
