Our Pigment Paste Sigma mixer has an Excellent for kneading and mixing of highly viscous materials like dough, putty, rubber solutions, adhesives, polymers etc. The mixing action is a combination of smearing, stretching, folding, dividing and recombining as the material is processed between the sigma blades and the container walls. Jacket arrangement is provided for heating or cooling application. In bigger models the container is tilted by a hydraulic cylinder to ensure complete discharge of mass.
Pigment is a substance that can make an object color. Pigment (Pigment) is used to color powdery substance. It is insoluble in water, grease, resin, organic solvent and other media, but can be evenly dispersed in these media and can make the media color, but also has a certain hiding power. The production of pigments requires high purity and high coloring power, so kneaders are the only choice when producing high-level pigments.
We generally put the crude pigment and a certain fineness salt into the kneader at a certain ratio.After the two stirring pulps in the machine are rotated at different speeds and mixed thoroughly, a certain amount of solvent is added to mix it into a certain viscosity mixture. . With the rotation of the Sigma blade mixer mixing paddle, the material produces axial and radial bidirectional impact, extrusion, shearing and grinding between the mixing paddle, the mixing paddle and the container wall, so that the large particles of the pigment are broken, refined, and surface Spheroidization changes the crystalline state of the particles and produces products that meet the needs.
Sigma blade mixer produced pigments have good purity, high coloring power, strong dispersibility, excellent gloss and transparency and other comprehensive indicators.The color items and dispersion properties of the pigments can be adjusted by adjusting the material ratio, kneading temperature and kneading time to meet Different needs. After kneading the pigment and then undergoing corresponding surface treatment, the product quality is greatly improved
