Why can potassium polyacrylate, a super absorbent polymer, absorb much more water than itself?
The reason is that the resin contains polymer chains like rattan.Before absorbing water, these long polymer chains, which are tightly solid, are wound and curled around each other, and a mesh structure is formed between a part of the chain; when encountering water, the ions in the mesh structure repel each other because of the same charge, and the polymer chain is fully expanded as a result.In other words, the mesh structure at this time is like a large open net pocket, which can absorb and store a lot of water.
Potassium polyacrylate is used for underground non-dispersible low-solid mud, shear dilution of polymer systems, anti-collapse and flocculation, 1.This product is a non-corrosive and widely used well wall stabilizer.It has the effect of inhibiting the dispersion of mud shale and drill cuttings, and has the properties of reducing water loss, improving flow and increasing lubrication.It can inhibit formation pulping and be compatible with a variety of treatment agents.
It can improve the rheological properties of drilling fluid, coat the ground with drill cutters, and inhibit formation pulping.The presence of potassium ions can avoid the hydration and flaking of soft mud shale and brittle hard mud shale, and play a role in stabilizing the well wall.2.It has good compatibility with other treatment agents and can be used in non-dispersible drilling fluids and dispersed drilling fluid systems.3.Strong temperature resistance (≥180℃).
Potassium polyacrylate for drilling fluid is a non-toxic and non-corrosive well wall stabilizer, which is easily soluble in water.The product has the effect of inhibiting the dispersion of mud shale and drill cuttings, and has the properties of reducing water loss, improving flow and increasing lubrication.It can effectively inhibit formation pulping and be compatible with a variety of treatment agents. It is a widely used and ideal well wall stabilizer.The appearance is white or light yellow powder.
Potassium polyacrylate is a super absorbent resin. The main feature of the super absorbent resin is a polymer electrolyte containing ionic groups. The polymer chain has a special cross-linking structure. In case of water, it is like a large net pocket, which can hold a lot of water.The total absorbency and expansion capacity are controlled by the type and degree of crosslinking with the polymer.Low-density crosslinked superabsorbent polymers usually have a high water absorption capacity and expand to a relatively large extent.High-crosslinked density polymers show low absorption capacity and expansion capacity.
