Polyacrylamide is a polymer that can exist in various forms depending on its molecular weight and the intended application. Here are the common forms of polyacrylamide:
1. Powder or Granular Form: Polyacrylamide is often manufactured and supplied in the form of a fine powder or granules. This form i...
Principle of action of polyacrylamide:
The molecular chain of polyacrylamide is very long, so that it can bridge between two particles and accelerate the settlement of particles. It is a good flocculant.
Industrially, polyacrylamide and its derivatives are produced by free radical polymerizat...
Environmental effects
Considering the volume of polyacrylamide produced, these materials have been heavily scrutinized with regards to environmental and health impacts.
Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen.Thus, concerns naturally center on th...
Description and Purpose
PAM increases the soil’s available pore volume, thus increasing infiltration and reducing the quantity of stormwater runoff that can cause erosion. Suspended sediments from PAM treated soils exhibit increased flocculation over untreated soils.
The increased flocculation...
1. Polyacrylamide dry powder or polyacrylamide emulsion usually can not be used directly, need to be diluted with water in a certain proportion, to be completely dissolved after use.
2. Dissolve polyacrylamide water with clean tap water, can not be sewage. Normal temperature water can be, gen...
Polyacrylamide (abbreviated PAM), with the formula -[CH2CH]nCONH2-, is a polymer formed from the polymerization of acrylamide monomers.
Polyacrylamides are classified as non-ionic (NPAM), cationic (CPAM), anionic (APAM) and Amphionic (Amphionic PAM).
Polyacrylamide application:
Polyacrylamide...
The technical indicators of polyacrylamide are generally molecular weight, hydrolysis degree, ionic degree, viscosity, residual monomer content, etc., so the quality of PAM can also be judged from these indicators!
1. Molecular weight
The molecular weight of PAM is very high and has be...
Polyacrylamide anions and cations are very different, they are polymer flocculants, anions and cations of their two different models, they can not be mixed, mixed use will react, lose the effect of the agent.
Anionic polyacrylamide is mainly used for flocculation, sedimentation and clarification of...
Polyacrylamide is a versatile polymer that is used in various applications, including water treatment, agriculture, cosmetics, and paper production. It is available in different forms, such as powder, granules, or emulsion, depending on the intended use. Here are some common methods of using polyacr...
Water treatment flocculants are chemical substances used to aid in the removal of suspended solids, organic matter, and other impurities from water during the clarification or filtration process. These flocculants promote the aggregation of fine particles into larger, settleable flocs, making it eas...
Polyacrylamide is a versatile water-soluble polymer that finds widespread applications in various industrial and environmental processes. It works primarily due to its high molecular weight and functional groups, specifically in terms of its ability to flocculate, or coagulate, particles and enhance...
The degree of hydrolysis of polyacrylamide refers to the extent to which the acrylamide monomers in the polymer have undergone hydrolysis. Polyacrylamide can be partially hydrolyzed, resulting in the formation of both acrylamide and acrylic acid units within the polymer chain.
The degree of hydrolys...
