What is the dispersion process of Lu'an Qing song Masterbatch Co. Ltd.?

The dispersion process of Lu'an Qing song Masterbatch Co. Ltd polypropylene masterbatch is a multi-stage and more complex physical process, involving the coordination of a variety of forces and material properties, as follows:

Initial mixing stage

When the Lu'an Qing song Masterbatch Co. Ltd polypropylene masterbatch and polypropylene raw materials are put into the processing equipment such as screw extruder, the mechanical external force begins to play a leading role. The rotation of the screw produces a strong shear force, which pushes the color masterbatch and the raw material particles to rub and collide with each other. At this time, the masterbatch particles as a whole are gradually broken up in this high shear environment, and the originally gathered masterbatches begin to break into smaller aggregates, which are initially mixed with polypropylene raw materials.

Because the masterbatch contains a dispersant, at this stage, the dispersant molecules also begin to be "active". One end of the dispersant is friendly to the pigment particles, and the other end has good compatibility with the polypropylene resin. Under the mechanical external force, it is like a "lubricant" and a "separator", which initially reduces the mutual attraction between the pigment particles and prepares for the subsequent finer dispersion.

Refinement and dispersion stage

As the material continues to move forward in the screw channel, the shear force becomes stronger and more uniform. With the help of dispersants, the pigment aggregates are continuously "disassembled" and become smaller and smaller in size, gradually refining from larger micron aggregates into smaller submicron or even nanoscale pigment particles. These particles begin to find their own "place" in the matrix of the polypropylene resin, and slowly achieve an initial uniform distribution.

At this stage, temperature also plays a key role. The temperature rise in the extruder makes the polypropylene resin gradually soften, the viscosity changes, and the fluidity is enhanced, which is more conducive to the pigment particles getting rid of the agglomeration and shuttling freely in the "embrace" of the resin, speeding up the dispersion process.

Stable dispersion stage

When the material is about to complete the entire extrusion process, after sufficient shearing and mixing, the pigment particles have been evenly dispersed in the polypropylene resin, forming a relatively stable system. At this time, the dispersant is tightly wrapped on the surface of the pigment particles, forming a steric hindrance effect, preventing the pigment particles from reuniting due to Brownian motion or weak external forces in the post-processing.

Finally, the material containing the uniformly dispersed pigment is extruded and formed to make a uniform color polypropylene product. The entire dispersion process ensures that the polypropylene products have no defects such as stains and color patterns on the appearance, and ensures the coloring quality and beauty of the products.
