Method of preparing an easily-dispersed rheology-grade product from a pseudolaminar silicate, product thus obtained and methods of using same |
摘要 |
The invention relates to a method of preparing a rheology product from a pseudomlaminar silicate comprising microfibre bundles. The inventive method comprises the following steps consisting in: grinding the pseudolaminar silicate mineral which is selected from sepiolite mineral, attapulgite mineral and combinations of same, with a pseudolaminar silicate concentration of at least 50%, moisture of less than 40% and a particle size of less than 1 mm; mixing the ground pseudolaminar silicate mineral with an aqueous solution of a dispersing component comprising at least one dispersing agent, in order to obtain a first mixture comprising between 35% and 85% water and between 0.1% and 7% dispersant in relation to the weight of the pseudolaminar silicate mineral; and intensively mixing the first mixture obtained in the second step until the dispersion of the pseudolaminar silicate microfibre bundles in order to obtain the rheology product in a dispersion homogeneously mixed with the dispersant and the water.
