FEIZHOU suspension agent is an organophilic attapulgite which controls the settling of solids in WATER-based drilling fluids. FEIZHOU suspension agent' of low viscosity muds with u s unique rheological structure suspends weighting materials and other solids with less increase in viscosity and gel strength than conventional bentonite or hectorite based organoclays. This allows the formulation ndiminished penetration rates and cutting removal. FEIZHOU suspension agent can be used alone or in conjunction with conventional organoclays. The solids suspension capacity of a fluid which is already thickened with an organoclay can be increased by the addition of FEIZHOU, without substantially increasing the viscosity of the system.
This thixotropic effect coupled with suspension and its rapid recovery provides many other beneits. For example, in paints & coatings, Attapulgite improves:
Another key feature is its rapid recovery. Mixtures quickly return to their original viscosity after mixing or after being applied. Unlike many thixotropes, Attapulgite product does not fade in that this shear-thinning effect can be repeated endlessly without loss of original viscosity.
Suspending agents are chemical substances useful in stabilizing a suspension. These are also known as thickening agents. These are usually hydrophilic colloids that spontaneously form colloidal dispersions with water. This happens due to an affinity between the dispersed particles and the dispersion medium.
Depending on the degree of stabilization required, the suggested use level for these ingredients is between 1% and 2.5%; they are not recommended above 2.5%. If the viscosity of the emulsion is insufficient, consistency agents should be added. Finally, to ensure stability regardless of what actives are used, the company recommends associating the materials with 0.2% xanthan gum.
