In the field of polymer materials and composite materials, inorganic mineral fillers are important, but they have poor compatibility with organic polymers. The modification machine can effectively improve their physicochemical properties by modifying the surface of inorganic powder fillers. For example, in the fields of plastics, rubber, adhesives, etc., the surface or interfacial properties of inorganic powder fillers differ from those of organic polymers, leading to poor compatibility and difficulty in uniform dispersion within the matrix. Direct filling can easily lead to a decline in the mechanical properties and brittleness of the material. The treatment by the modification machine can enhance the compatibility of inorganic powders with organic polymers and their dispersibility in organic matrices, thereby improving the mechanical strength and overall performance of the materials. Surface modification is a key processing method for transforming inorganic fillers into functional fillers, providing new technical methods for the development of polymer materials and organic/inorganic composite materials. / 无机复合材料的发展提供了新的技术方法。

Pigments in coatings are mostly inorganic powders that need surface modification to improve their dispersibility in organic matrices, thereby enhancing various properties of the coatings. In newly developed special coatings, fillers and pigments not only require ultra-fine particle sizes but also need to possess certain functions; therefore, surface treatment is necessary. For example, coating titanium powder with aluminum oxide or silicon dioxide can improve its weather resistance and other properties.

Water-based architectural decorative coatings require inorganic pigments and fillers to have dispersion stability and rheological properties, which necessitates surface modification.。Surface treatment of some powder raw materials can endow products with good gloss and decorative effects, increasing product value. For instance, after surface modification of mica powder with metal oxides, it can be used in cosmetics, plastic products, etc., imparting a pearlescent effect to the products.。

在无机 In new inorganic/inorganic composite materials, the dispersibility of inorganic components affects material performance. Ceramic pigments with good dispersibility can enhance product color quality while reducing usage. For example, using ceramic pigments with good dispersibility in colored ceramic tiles can elevate product quality.。Intercalation modification can produce new interlayer compounds with new physical and chemical properties or functions, thus expanding their application range. For example, intercalation compounds made from graphite through interlayer chemical treatment greatly outperform graphite itself and have expanded their application range to multiple fields.

Different types of modification machines each have their own characteristics.The honeycomb mill is a modification machine specifically designed for producing ultra-fine powders. It uses an air-swept system that provides good dispersion for powders and surface modifiers, ensuring uniform coating on particle surfaces. It is particularly suitable for surface modification of ultra-fine powders. The honeycomb mill can operate continuously with a large processing capacity, making it suitable for industrial production at various scales. The utilization rate of modifying agents is high, with high powder coating rates and activation indices while maintaining low energy consumption.。The high-speed gas-solid phase vortex mixing operation of powders and agents ensures high modification efficiency without significantly damaging the original particle shape of the powders. It has good sealing properties with minimal dust leakage, resulting in almost no pollution, a favorable operating environment, and low labor intensity. The powder coating rate and activation index are high, with coating rates reaching up to 99.2% and activation rates reaching 99.8%. It also features spheronization and drying functions.可以It can meet the processing needs of different materials and provide strong support for material development.
