    Anionic polyacrylamide


    Anionic polyacrylamide

    Anionic polyacrylamide (APAM) is a highly polymerizable water-soluble linear polymer. Free-flowing and free-flowing microparticle-like or gelatinous supply, completely soluble in water, and due to its micro-form, can quickly dissolve. Different types of polyacrylamide have different active groups, can make different suspended particles flocculation, easy to filter, separation. Polyacrylamide is almost insoluble in any organic solvent and is soluble in water. In many industries are widely used in flocculation, thickening, bonding, scale inhibition, stable colloid, drag reduction, film, gel and biological materials. According to different uses are divided into two production processes, a homopolymer (non-ionic polyacrylamide before hydrolysis), a copolymer (acrylamide and acrylic acid or sodium acrylate).
    Anionic polyacrylamide technical indicators First, the product description:
    Anionic polyacrylamide (APAM) appearance of white powder, molecular weight from 600 million to 25 million water solubility, and can be dissolved in any proportion of water and insoluble in organic solvents. Effective pH range of 7 to 14, in the neutral alkaline medium was high polymer electrolyte characteristics, and salt electrolytes sensitive, and high-priced metal ions can be cross-linked into insoluble gel.
    Second, the product features:
    1, flocculation: PAM can make suspended substances through the electrical neutralization, bridging adsorption, from the role of flocculation.
    2, adhesion: through mechanical, physical, chemical role, from the role of bonding.
    3, drop resistance: PAM can effectively reduce the friction of the fluid, the water can be reduced by adding trace PAM 50-80%.
    4, thickening: PAM in the neutral and acidic conditions are thickening effect, when the PH value of 10 or more PAM easy hydrolysis, semi-reticular structure, the thickening will be more obvious.
    Third, the main technical indicators:

    Fourth, use:
    1, dissolved method:
    Dissolve the solid in a concentration of 0.1-0.5% before use, so that it can quickly exert its potency. When dissolving, stir the water in the dissolving tank and add the solid to the mixture so that it is uniformly dispersed in the water. It forms pimple. Due to a long time for a strong stirring, it will make its performance is reduced, it is recommended to stir the mixer to 20-200 per minute or so to dissolve. Because if the solution is placed for a long time, its performance will be gradually reduced depending on the water quality, so after the aqueous solution is modulated, please use it within three days.
    2, the addition of dissolved solution:
    Usually, about 0.1% of the aqueous solution is added. However, when the aqueous solution is further diluted to about 0.01% in the case of high concentration and high viscosity of the suspension, it is easy to mix and exert a sufficient effect. After the addition of the flocculant aqueous solution to the suspension, agitation will occur if agitated for a long period of time, so that the flocculant has been formed. Therefore, add the formulated aqueous solution before the flocculation process is to be carried out.
    Fifth, the main purpose:
    Mainly used as flocculant: As the anionic polyacrylamide chain contains a certain amount of polar function to adsorb suspended solids in water, so that the bridge between the particles to form a large floc. So it accelerates the settling of the particles in the suspension, which obviously speeds up the clarification of the solution and promotes the filtration and the like. The product is used for chemical industry wastewater, waste treatment, municipal sewage treatment, water industry, high turbidity water purification, clarification, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronics industry and other water treatment.
