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...
As soon as you hear the name polyacrylamide, you know that it is a chemical product. When it comes to chemical products, many people always worry about whether it is toxic. Let me explain to you whether it is toxic.Polyacrylamide is a linear polymer, and its products are mainly divided into two form...
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 according to ionic characteristics can be divided into non-ionic, anionic, cationic polyacrylamide types. According to the molecular weight to have different specifications of molecular weight, ionic degree and so derived a lot of models, in the face of the market messy specifications...
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...
Acrylamide is a colorless crystalline chemical, an unsaturated amide, which is widely used in industry. It is also the main chemical raw material for the production of polyacrylamide, and is widely used in water purification treatment, pulp processing, pipeline coating and other industries.
A...
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...
