Industrial grade sodium polyacrylate wtih factory price

 sodium polyacrylate

sodium polyacrylate Uses:

    High relative molecular mass for flocculants.

    Water treatment agent - flocculant

    sodium polyacrylate is a linear, soluble polymer compounds, the molecular chain of the carboxyl group due to electrostatic repulsion, so that the winding around the polymer chain stretching, contributed to the adsorption of functional groups exposed to the surface, because of these The active point adsorbed on the suspended particles in the solution to form the bridge between the particles, thus accelerating the sedimentation of suspended particles. As the flocculant sodium polyacrylate its molecular weight up to several million, the commercial form of yellow viscous liquid, solid content or up to 8% Xu, the corresponding intrinsic viscosity η ≥ 3.40.

    Sodium polyacrylate flocculant is particularly suitable for caustic soda and soda ash industry, salt refining, alumina production of red mud sedimentation separation, monosodium glutamate wastewater protein recovery and sugar and other industries of polymer materials.

    Papermaking Chemicals

    Papermaking chemicals Papermaking coatings as dispersants. The most suitable relative molecular mass is 2000-3000. The commodity form is generally 30% or 42% solids. The viscosity is less than 600 mPa.s. Appearance colorless and transparent to amber liquid. The pH is between 6-9.

    Other areas

    Water - based paint, from the dispersion effect;

    Textile auxiliaries, from the slurry dispersion;

    Ceramic processing aids, from the dispersion effect;

    Detergents as detergent additives, from the dispersion; anti-fouling redeposition and thickening effect;

    Sanitary napkin, from the role of water

     Crystal mud, from the role of water

Sodium polyacrylate physical and chemical properties:

White powder, odorless and tasteless. Strong absorption of wet. Is a polymer having both hydrophilic and hydrophobic groups. Can be slowly dissolved in water to form a very viscous transparent liquid. 0.5% solution viscosity of about 1 Pa · s, the viscosity and CMC roughly equal to 15 to 20 times that of sodium alginate. Heat treatment, neutral salts, organic acids have little effect on its viscosity, alkaline conditions, the viscosity increases. Insoluble in ethanol, acetone and other organic solvents. Strong heat to 300 ℃ does not decompose. Jiucun viscosity change is minimal, not easy to corruption. In case of divalent metal ions (such as aluminum, lead, iron, calcium, magnesium, zinc) to form its insoluble salt, causing molecular crosslinking and gel precipitation. When the pH is 4 or less, the polyacrylic acid precipitates.

Processing or manufacturing methods:

Acrylic acid or acrylic acid and sodium hydroxide reaction of sodium acrylate monomer, remove the side of the alcohol, by concentration, adjust the pH value, ammonium persulfate for polymerization catalyst derived.

sodium polyacrylate Description:

Chemical Name: Sodium Polyacrylate (PAAS)

English name: sodium polyacrylate

Molecular structure: - [- CH2CHCOONa -] -

sodium polyacrylate is a kind of polyanionic polymer dielectric, is a modern development of a very wide range of important uses of chemical products. In environmental protection, food, medicine, textile, water treatment, petrochemical, metallurgical and other departments have a wide range of applications. Sodium polyacrylate includes water-soluble and water-swellable two categories, water-swellable sodium polyacrylate is a high absorbent resin category Another type of water-soluble sodium polyacrylate due to its different molecular weight and have different Is widely used in food, feed, textile, paper, water treatment, petrochemical, agriculture, forestry, horticulture, health and other areas of sodium polyacrylate acrylic acid as raw materials by sodium hydroxide after polymerization and can also be other single Sodium acrylate copolymer was prepared by copolymerization of sodium acrylate and sodium acrylate, and the properties of sodium polyacrylate were modified to synthesize sodium polyacrylate copolymer with special properties.

Liquid:25kg or 200kg in plastic barrel. Solid:25kg poly woven bag with inner lining.
