Natural Golden Pearlescent Pigment Wholesale

What are the factors that affect the dispersibility of natural gold pearlescent pigments?
Factors that affect the dispersibility of natural gold pearlescent pigments include:
The size of the pigment particles affects its dispersibility in the substrate. Smaller particles are generally easier to disperse in the substrate, but may require a more sophisticated dispersion process.
The shape of the particles affects its dispersibility in the substrate, for example, flake or needle-shaped particles may have different dispersibility than spherical particles.
The surface treatment of the pigment particles affects its dispersibility in the substrate. Surface treatment of pigment particles can improve its compatibility with the substrate and improve dispersibility.
The chemical properties of the substrate, such as polarity, viscosity, and surface tension, affect the dispersibility of the pigment.
The type of dispersing equipment and process used, such as high-speed agitators, three-roll mills, ball mills, etc., will affect the dispersibility of the pigment.
The dispersing medium used, such as water, alcohol, oil, etc., will affect the dispersibility of the pigment.
The higher the concentration of the pigment in the substrate, the more difficult it may be to disperse.
Including temperature, pressure, mixing speed, etc., these conditions will affect the dispersibility of the pigment.
Various additives used, such as dispersants, stabilizers, surfactants, etc., can improve the dispersibility of the pigment.
Environmental factors such as humidity and temperature may also affect the dispersion of pigments.

How do processing conditions affect the dispersion of natural golden pearlescent pigments?
Processing conditions have a significant impact on the dispersion of natural golden pearlescent pigments. Here are some of the major processing conditions factors and how they affect pigment dispersion:
Temperature is one of the key factors affecting pigment dispersion. During processing, an increase in temperature can reduce the viscosity of the substrate, allowing the pigment to disperse more easily. However, excessively high temperatures may cause thermal degradation of the pigment particles or excessive reaction of the substrate, thereby affecting the stability and dispersion of the pigment.
During certain processing processes, such as extrusion or injection molding, increased pressure can promote the dispersion of pigments in the substrate. The pressure helps overcome the adhesion between pigment particles, allowing them to be more evenly distributed in the substrate. However, excessive pressure may lead to the breakage of pigment particles or excessive shearing of the substrate, affecting the quality of the final product.
The mixing speed directly affects the mixing efficiency of the pigment and the substrate. Proper mixing speed can ensure that the pigment particles are evenly dispersed in the substrate, while mixing speed that is too high or too low may lead to uneven dispersion. High-speed mixing may increase dispersion efficiency, but may also result in fragmentation of pigment particles or excessive shearing of the substrate.
The length of mixing time affects how well the pigment is dispersed. Longer mixing times help the pigment particles disperse more fully into the substrate, but too long mixing times may result in over-dispersion of the pigment or degradation of the substrate.
Stirring methods, such as mechanical, ultrasonic or high shear mixing, can affect pigment dispersion. Different stirring methods have different shear forces and dispersion effects on pigment particles. Choosing the appropriate stirring method can improve the dispersion efficiency.
The viscosity of the substrate affects pigment dispersion. Highly viscous substrates may hinder the movement of pigment particles, resulting in uneven dispersion. By adjusting the base material formulation or processing conditions, the viscosity can be reduced and pigment dispersion improved.
The order in which pigments are added also affects their dispersibility. Generally, pigments should be added after the base material is thoroughly mixed to reduce agglomeration and precipitation of pigment particles.
In some cases, pigments require pre-treatment such as drying, surface treatment or grinding before being added to the substrate. These pretreatment steps improve pigment dispersion.
Environmental conditions, such as humidity and temperature, also affect pigment dispersion. For example, a high-humidity environment may affect the viscosity of the substrate and the fluidity of the pigment, thereby affecting the dispersion effect.
The concentration of the pigment is also an important factor. High concentrations of pigments may increase the difficulty of dispersion due to increased interactions between pigment particles and the tendency for agglomerates to form.
