environmental anionic polyacrylamide for cement making
Polyacrylamide in Cement Concrete Modification - CHINAFLOC
Polyacrylamide can be used to modify the cement concrete in order to improve its flexural strength, its bond strength and its flexural toughness, and its abrasion resistance has a significant effect, it can reduce the crushing ratio, the permeability and the contractility.. Along with the increase in traffic and overloading phenomenon, the destruction of the pavement and bridge deck pavement
Effect of polyacrylamide on rheology of fresh cement
In this paper, we study the effects of polyacrylamide (PAM) on both aqueous solutions and fresh cement pastes. Our solution viscosity and hydrodynamic radii measurements in various solutions suggest that calcium ions lead to a cross-linking of anionic PAM and to the formation of PAM micro-gels.
Anionic Polyacrylamide by Yongxing Environmental
Anionic polyacrylamide Polyacrylamide is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type.
Anionic polyacrylamide - wastewater treatment chemicals
Anionic polyacrylamide is water-soluble linear polymer synthesized with high degree of polymerization. It is widely used in oil recovery, mineral processing, metallurgy, chemical industry, papermaking, textile,medicine, environmental protection, building materials, agriculture and other industries.
Application of anionic polyacrylamide-Henan Yuanbo
Anionic polyacrylamide is an ultra-high molecular weight polymer copolymerized by acrylamide and acrylate. It has a molecular weight of 18 million or more. It has strong adsorption and bridging efficiency. It can be used according to different uses and users' requirements for product performance.

Nonionic Polyacrylamide Flocculant
SINOFLOC nonionic flocculants are technically pure polyacrylamides.Nonionic polyacrylamide exhibits neutral nonionic properties in the aqueous solution which is hardly influenced by the PH value in the application. SINOFLOC nonionic flocculants are suitable for use as a settlement aid in many different mineral-processing applications and are particularly effective under very low PH conditions
The difference of anionic, cationic and Non-ionic
Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide
The Usage of The Polyacrylamide in The Paper Making
In the above mentioned applications of the anionic polyacrylamide, different flocculating agents have different functions. The polyacrylamide PAM worked as the paper strengthening agent and the dispersing agent in the paper making from the recycled papers, in order to keep the strength of the paper tensile, to keep the good performance of the paper products, and also to meet the need of the
Polyacrylamide in Water Treatment
In general, cationic polyacrylamide for the treatment of organic sludge, anionic polyacrylamide for the treatment of inorganic sludge, alkaline is very easy to use cationic polyacrylamide, and acidity should not use anionic polyacrylamide, when the solid content of mud is high, the amount of polyacrylamide is usually large.
Synthesis, Characterization, and Flocculation Properties
Abstract. A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization was initiated using potassium diperiodatocuprate, K 5 [Cu(HIO 6) 2](Cu(III)), initiating the self-condensing vinyl copolymerization of acrylamide and acryloxyethyltrimethyl ammonium chloride (DAC) monomer.The resulting copolymer was characterized by the use of
