2021年3月1日 This sedimentation process has been, at first, studied by in situ X-ray powder diffraction, thermogravimetric techniques and X-ray tomography and then inhibited by exploiting finer barite sources, implementing a grinding procedure, combined to a surface modification of the inorganic additives. Stearic acid and sodium dodecyl sulfate were

Tengmin owns large material ore mine to keep producing constantly. Given advanced equipments, Tengmin posses the ability to process kinds of fine chemicals, Such as sub micron grade Precipitated Barium Sulfate (D50, 0.8um), sub micron grade Precipitated Silica and some other basic chemicals.
Read MoreBarium sulfate is extracted from mined barites, and undergoes grinding and classification to yield particles sizes suitable for use in coatings. As mentioned previously, barium sulfate has a higher specific gravity ( ρ = 4.5 g cm −3 ), and hence leads to higher specific gravity coatings, or lower coverage coatings (i.e., the coating covers a ...
