Application of sodium polyacrylate dispersant

Page view
[Abstract]:
A "dispersant" is a surfactant having both opposite properties of lipophilicity and hydrophilicity in a molecule.

A "dispersant" is a surfactant having both opposite properties of lipophilicity and hydrophilicity in a molecule. The solid and liquid particles of inorganic, organic pigments which are difficult to dissolve in the liquid can be uniformly dispersed, and the sedimentation and aggregation of the particles can be prevented, and the amphiphilic reagent required for the stable suspension can be formed.

Sodium polyacrylate is a new type of functional polymer material and important chemical products. The solid product is white (or light yellow) block or powder, and the liquid product is colorless (or light yellow) viscous liquid. Dissolved in cold water, warm water, glycerin, propylene glycol and other media, stable to temperature changes, has the effect of fixing metal ions, can prevent the negative effects of metal ions on products, is a surfactant with a variety of special properties.

Sodium polyacrylate as a dispersant is an additive that can improve and improve the dispersion properties of solid or liquid materials. When the solid dye is ground, a dispersing agent is added to help the particles to pulverize and prevent the agglomerated particles from agglomerating to keep the dispersion stable. It is widely used in white clay, china clay, calcium carbonate, talc powder, titanium dioxide, aluminum hydroxide, zinc oxide and other pigments. It can also be used to mix pigments to solve the problem of difficult pigment dispersion and low fluidity. Realize the pipeline transportation of pigments. Used in paper, paint, printing and other industries.

In the paper industry, it is mainly used in the coating of high solid content knife coater coatings and high quality paper, coated paper, whiteboard paper, etc., and can improve the surface properties of paper and reduce paper disease.

Method of use: The amount of the product is determined according to different pigments, and the ratio is usually 0.1% to 1.5%, and is added to the high-speed dispersing machine together with the pigment.
