How to Control Polyacrylamide Viscosity The viscosity of polyacrylamide aqueous solution is influenced by the solution viscosity, ph value, shear rate and the relative molecular polymer. polyacrylamide solutions viscosity and concentration are similar to the logarithmic relationship. High molecular weight polyacrylamide concentration is difficult to deal with when the concentration is over 8%. Increasing the temperatureContinue reading “How to Control Polyacrylamide Viscosity”

How Polyacrylamide Works for Papermaking Industry
A considerable amount of information has been reported on how various polymeric additives affect drainage rate and fines retention. When used as a drainage aid, polyacrylamide can overcome slow drainage of fiber furnishes containing high-yield pulps such as stone groundwood, hardwood pulps and recycled fiber furnishes. In addition, these additives improve the drainage of high-base-weightContinue reading “How Polyacrylamide Works for Papermaking Industry”
Friction Reducer Application History in Oilfield
The concept of drag reduction was first proprosed in the 1940s. In the early 20th century, firefighters in New York used water-soluble polymers to increase the flow of the drainage system. In 1948, a small amount of polymethyl methacrylate (PMMA) was dissolved in chlorobenzene, and the friction resistance could be reduced by about 50%. InContinue reading “Friction Reducer Application History in Oilfield”
Enhanced oil recovery (EOR) – Polymer Flooding
eor polymer is a substance that greatly increases the viscosity of the liquid which mixed with this polymer and water. Polymer flooding is mainly to use polymer to increase the viscosity of injected water, reduce the ratio of oil to water flow, and increase sweep efficiency. Firstly, from the rheology of the polymer, it can beContinue reading “Enhanced oil recovery (EOR) – Polymer Flooding”
Anionic Polyacrylamide Used in Mining
Coal washing anionic polyacrylamide applications involve mining, beneficiation and metallurgy. Using polyacrylamide can accelerate the settling of effective solids the concentration of small objects, and improve the solid-liquid separation effect, reduce tailings loss and environmental pollution, and also reduce production costs. Under normal circumstances, the process of mineral processing requires high molecular weight products to ensureContinue reading “Anionic Polyacrylamide Used in Mining”
Mechanism and Dissolution Process of Amphoteric Polyacrylamide As Dispersant
1. The mechanism of action of amphoteric polyacrylamide as a dispersant The surfactant can make the solid dispersed particles in the suspension be fully wetted and uniformly dispersed by the liquid phase, and minimize the separation and aggregation of the system and the sedimentation speed of the solid particles to maintain the maximum dynamic stabilityContinue reading “Mechanism and Dissolution Process of Amphoteric Polyacrylamide As Dispersant”

Extraction of Aluminium in Fly Ash
There are three main types of extraction of Aluminium: (1) Sulfuric acid refining: 1. The fly ash is ground and calcined and activated, and then leached by sulfuric acid and concentrated to obtain aluminum sulfate crystals; 2. after calcination, an alkaline solution is added; 3. using iron removal technology, Aluminum hydroxide is obtained; 4. ItContinue reading “Extraction of Aluminium in Fly Ash”
Drilling Fluid Additives – Drilling Mud Viscosifier
Drilling Fluid Additives – Drilling Mud Viscosifier In the drilling operation, the anionic polymer is often used as drilling fluid additives to increase the viscosity of the drilling fluid. It is divided into dry powders and emulsions. The emulsions are prepared into water-in-oil (W/O) by inverse emulsion polymerization. They have the characteristics of fast dissolution, easyContinue reading “Drilling Fluid Additives – Drilling Mud Viscosifier”
