Nonionic Polyacrylamide Powder (NPAM)

Product Information

        Polyacrylamide (PAM for short) is a commonly used artificial flocculant. It is easily soluble in water and easily decomposed when the temperature exceeds 120°C. The product has properties such as flocculation, thickening, shearing, drag reduction, and dispersibility. The solid is white or slightly yellow powder, the liquid is colorless and viscous, and the colloidal product is colorless and transparent. Anionic, cationic, nonionic, and zwitterionic polyacrylamide can be obtained by chemical modification.

       The homopolymer formed by the polymerization of a single acrylamide is nonionic, and its molecules are not charged. The copolymer formed by the copolymerization of acrylamide and anionic monomers (such as sodium acrylate) is anionic, and its molecules are negatively charged. For the same reason, the copolymer generated by acrylamide and cationic monomers is cationic, and its molecules are positively charged.

      The copolymer contains some ionic monomers, which shows partial ionic characteristics. We use the percentage of ionicity to express the charge on the polymer molecular chain. The higher the ionicity, the more charged the molecular chain is. In this way, the ionicity of nonionic polyacrylamide is zero. What charge (i.e. ionicity) and how much charge (i.e. ionicity) the polyacrylamide molecular chain carries are important considerations when selecting polyacrylamide flocculants.

        Polyacrylamide is a synthetic polymer with a relatively high molecular weight. The molecular weight of polyacrylamide always refers to the average molecular weight, which indicates the average length of each polymer molecule. The larger the molecular weight, the more chain segments each molecule contains, or the longer the average length of each molecule. From the perspective of molecular weight, the flocculation effect of polyacrylamide is not only related to the molecular weight, but also to the molecular structure (straight chain, branched chain, cross-linked) and molecular weight distribution (wide, narrow).

Product Category

         Homopolymers formed by the polymerization of single acrylamide are non-ionic polyacrylamide, whose molecules are uncharged and the ionicity of non-ionic polyacrylamide is zero.

         Non-ionic is a high molecular weight, low ionicity polymer, which has the functions of flocculation, dispersion, thickening, bonding, film formation, gelation, and colloid stabilization. Its flocculation performance is less affected by pH value and salt. In the treatment of acidic wastewater, its effect is better than that of anionic polymers.

         Non-ionic polyacrylamide (NPAM): It is formed by homopolymerization of acrylamide. It is a linear polymer or polyelectrolyte with high 
molecular weight, low hydrolysis degree and strong flocculation ability. The molecular chain contains a certain number of polar groups.
It can adsorb solid particles suspended in water to bridge particles or condense particles to form large floccules through charge neutralization,
thereby accelerating the sedimentation of particles in the suspension, and has a very obvious effect of accelerating the clarification of the solution
and promoting filtration.

Application:

Application range of nonionic polyacrylamide:

1. Textile industry auxiliaries

     Adding some other chemicals can make chemical slurry for sizing textiles, which can improve adhesion, permeability and desizing performance,
make textiles anti-static, reduce slurry spots, cloth machine breakage rate and falling objects, so it has become a necessary chemical auxiliaries
in the textile industry.

2. Can be used for sewage treatment

     When the sewage is acidic suspension, it is more appropriate to use nonionic polyacrylamide as a flocculant. At this time, PAM plays an
adsorption role, causing the suspended particles to flocculate and precipitate, so as to achieve the purpose of purifying water.
It can also be used for drinking water treatment. This product is non-toxic, especially when used in combination with inorganic flocculants,
it has a very good effect on water treatment.

3. Chemical grouting agent

     Using 9.5 parts of nonionic polyacrylamide and 0.5 parts of N, N-methylene bisacrylamide can be used as a chemical grouting agent for water
blocking in dams, tombs, tunnels, etc.

4. Sand control and sand fixation

    Make nonionic polyacrylamide into a 0.3% solution, add a crosslinking agent, and spray it on the desert to prevent sand and fix it.
It is low-cost and convenient, and is one of the effective methods to control desertification.

5. Soil moisturizer

   Nonionic polyacrylamide has strong hygroscopicity. It can retain soil moisture. In arid areas, this product can improve the soil.

6. Oilfield profile control and water plugging agent

     Nonionic polyacrylamide and essential cellulose are combined, and then certain chemical additives are added to it, which can be used as an
oilfield profile control and water plugging agent.

Safety instructions:

    Leakage treatment: It is easy to slip when it comes into contact with water or moisture. If it overflows or leaks, people should be evacuated in
time and cleaned up quickly.

    Safety measures: When using dry powder products, be careful to prevent dust from being raised and entering the eyes; try to avoid prolonged
 contact between the product and the skin; after skin contact, wash with water immediately.

Storage method:

     Please store in a sealed, dry and ventilated condition. Under correct storage conditions, the dry powder is valid for two years.

Product packaging:

    The product is double-layered. The inner packaging is a plastic moisture-proof film, and the outer packaging is a composite kraft paper bag.
The net weight of each bag is 25 Kgs.
