In the plastics, rubber, and coatings industries, ceramic fillers, with their high hardness, high-temperature resistance, and corrosion resistance, are key components in enhancing material properties. However, due to their high surface energy and strong polarity, raw ceramic fillers have poor compatibility with organic matrices, easily leading to uneven dispersion and weak interfacial bonding, limiting their application in high-end materials. Ceramic filler modification machines, through innovative surface treatment technologies, not only solve traditional processing problems but also drive a qualitative leap in the performance of composite materials.

Ceramic filler modification machines use coating technology, through high-speed shearing, friction, and chemical reactions, to construct a nanometer-scale modified layer on the surface of ceramic particles: Using coupling agents such as silanes and titanates, a chemically bonded layer is formed on the ceramic surface, changing the filler surface from hydrophilic to hydrophobic, significantly improving the interfacial bonding strength with the polymer matrix. For example, silane-modified alumina fillers can increase the tensile strength of composite materials by more than 30% ； Through free radical polymerization or ring-opening polymerization, polymer molecules are grafted onto the ceramic surface, forming a “core-shell” structure. This modification method not only improves dispersibility but also imparts functionalities such as enhanced toughness and flame retardancy to the filler. For example, polypropylene-grafted silicon carbide fillers can improve the impact strength of plastics by 50%.
Introducing functional nanomaterials such as nano-titanium dioxide and graphene, through synergistic effects, enhances the thermal conductivity, electrical conductivity, or antibacterial properties of ceramic fillers. For example, titanium-modified nano-silicon dioxide powder can improve the wear resistance of coatings by 40%.

The honeycomb mill is a continuous powder surface modification machine specifically designed for surface modification or surface treatment coating of ultrafine powder particles. The equipment mainly consists of a depolymerization wheel, discharge port, air intake, classifier, main body, feed port, multi-path surface dispersant inlet, and feeder. Its unique structure and scientific working principle can fully ensure that the powder and surface modifier achieve good dispersion effects, and allow the powder and surface modifier to have equal contact or interaction opportunities, fully meeting the relevant technical requirements.
