Product Description
As a coloring agent, pigments are widely used in various fields: such as coatings, paints, inks, plastics, textiles, cosmetics, food, etc.
According to the properties of pigments, coloring agents can be roughly divided into two types: soluble pigments and insoluble pigments. Clearly, soluble pigments do not require further grinding through equipment.
Therefore, in the production of pigments, how to select the grinding equipment for pigments generally speaking, refers to the insoluble type of pigments.

Due to the non-volatility of the pigments, their coloring intensity and color purity are directly influenced by the size and morphology of the pigment particles. Therefore, choosing an appropriate dispersion and grinding process will significantly enhance the coloring performance of the pigments on the base material.
The pigment dispersion and grinding process mainly involves the use of high-speed dispersers and sand mills.
Taking the production of color paste as an example: specifically, it involves several steps such as material preparation, pre-mixing of ingredients, dispersion and grinding, color matching and paint production, filtration, and packaging.
Pengyi Intelligent High-Speed Dispersing Machine

The dispersion state of the pigment, the surface polarity, and the particle size and distribution of the pigment particles will all directly affect its storage and application performance. The quality of dispersion not only affects the tinting strength and hue but may also have some impact on the optical stability of the coating.
When the pigment particles are evenly distributed in the paint in the form of small particles with large surface areas, the pigment particles are fully surrounded and isolated by the paint, and the attraction between them weakens. They are no longer likely to re-agglomerate into large particles, thus achieving a stable state. At the same time, the overall coloring power and covering power of the pigment slurry will be enhanced, and the gloss and smoothness of the film formation will be better.
Pengyi Intelligent Pin Type Efficient Nano Bead Mill Machine

Thanks to its completely independently developed, designed, and assembled grinding equipment, Pengyi Intelligent Nano Grinding Machine possesses an astonishing fine grinding capability with nano-level fineness.
The rod-pin grinding structure of Pengyi sand mill is particularly suitable for grinding heat-sensitive products and materials that are difficult to disperse; it adopts a dynamic screen bead material separation system, providing continuous large-flow output; the four-in-one cooling system precisely controls the temperature inside the chamber to ensure that the grinding materials do not deteriorate; different rotor configurations can be selected according to the grinding materials to improve efficiency and prevent the materials from rusting or changing color. Compared with traditional sand mills, its efficiency has increased by 2-3 times.
If the processed product is organic pigments, special attention needs to be paid to the characteristics that may cause explosions. This mainly involves critical energy, critical temperature, and Kst values. Based on these data, when the limits are exceeded, adequate protection must be provided. Pengyi's equipment all supports customized explosion-proof solutions.
By using the appropriate dispersion and grinding equipment process, high-quality pigments with specific requirements can be produced, meeting the final required fineness and quality standards of the products. Such dispersion and grinding processes can also increase the value of the products of the manufacturing enterprises, reduce energy consumption, and reduce other production costs. Let Pengyi equipment become the core competitiveness of your enterprise and achieve win-win cooperation together!
