Sinofloc Concrete additives are chemicals and materials blended into the cement to alter its performance. Additives provide a specific benefit for a particular job. Liquid additives used during cement grinding improve the strength of the cement. Concrete bonding additive bonds old concrete to new for interior and exterior jobs like wall capping and resurfacing. Color additivesContinue reading “Introduction of Concrete Additives”

The polyacrylamide viscosity 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 temperature could decrease the viscosity, but the effectContinue reading “How to Control Polyacrylamide Viscosity”

How Polyacrylamide Works for Papermaking Chemical 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 for printing can overcome slow drainage of fiber furnishes containing high-yield pulps such as stone groundwood, hardwood pulps and recycled fiber furnishes. In addition,Continue reading “How Polyacrylamide Works for Papermaking Industry”

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 ) – Polymer Flooding 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 theContinue reading “Enhanced oil recovery (EOR) – Polymer Flooding”

Anionic polyacrylamide uses 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 ensure rapid settling,Continue reading “Anionic Polyacrylamide Used in Mining”

1. The mechanism of action of amphoteric polyacrylamide dispersant 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”

SINOFLOC is offering a new range of synthetic polyacrylamide that can be used as Guar alternative, with main functions of opening the fractures and transporting and keep the proppant in place alone the length of the fracture. This technology could be used in Polymer Gelled Carrying Fluid System which could reduce the number of oilfieldContinue reading “Guar Alternative”
