Oil and gas

Polymer can be used as additive for various purposes in oil production, such as drilling fluid, fracturing fluid and polymer flooding to enhance oil recovery (EOR), due to its properties in thickening and flocculation and rheological properties.

In oil exploitation, how to design and select its composition and structure, such as molecular morphology and weight distribution, ionic charge and correct dosing techonology is critical for a specific application.

When EPOLBIND is used as drilling fluid additive, Binder is adsorbed on the metal' surface or clay particles, forming a liquid film, which changes from solid surface friction to liquid friction, thus lubricating the drilling tool, reduces mud cake friction coefficient and downhole accidents. The suspension ability of Polymer in drilling fluids is of great importance in oil and gas production and other industries. Suspension refers to the resisting action of suspended ions as they move relative to the medium under the action of the applied force field.

Iron and steel

The need of reduce as much as possible the amount of waste generated during the activity in the iron and steel industries, has promoted the reciclyng.

These residues, with a high iron content, make the cold extrusion or briquetting process require a binder that holds the residues together.

For that, the use of polymeric binders, and specifically EPOLBIND polymer binder, is an optimal solution.

Mining

In the mining industry, the effective separation of the mineral solids from the water, or the aquaeous solutions, is fundamental. If the flocculation process is not effective during the sedimentation or centrifugation process, the heaviest inorganic solids can drop to the bottom of the sedimentation tank and the lighter particles will be suspending on the supernatant.

Then, the efficacy of the filtration and drying is also reduced significatively by the presence of little quantitites of particles in the supernatant. But these particles can be rapidly sedimented by adding EPOLBIND  to the aqueous dispersion.

In this process, the suspending particles tends to aggregate in order to create larger aggregates more heavies that sedimented at the bottom, remaining on the surface the clear liquid.
