Compatibility issues of thermal conductive fillers with polymer matrix and the necessity of surface modificationThe addition of thermal conductive fillers to polymers can reduce the coefficient of thermal expansion, etc., but it will produce a matrix. - The filler and filler-filler interface, due to the mismatch of phonon vibration frequencies at the interface, causes a large amount of phonon scattering, resulting in the thermal conductivity of thermal conductive polymer composites being far lower than expected. Therefore, eliminating or reducing phonon scattering caused by the interface is key to improving thermal conductivity, which requires surface modification of thermal conductive fillers to increase the interaction between fillers and polymer matrix, improving compatibility.

Adopting the advantages of "honeycomb grinding" for modification, such as high coating rate, activation rate, etc.In industrial production, the physical adsorption method mainly uses mechanical equipment. "Honeycomb grinding" is used for the coating of modifiers. The honeycomb grinding modification process is a pneumatic system that uses mechanical force to disperse and depolymerize thermal conductive fillers and inject them into the grinding chamber along with atomized modifiers, allowing them to intertwine and form a single-layer nano-coating film, with a coating rate of up to 99.2% and an activation rate of 99.8%. At the same time, it can also achieve grinding, drying, sorting, and drying depolymerization treatment of wet grinding filter cakes and slurries synchronously.

Characteristics and deep processing of barite powderBarite is a sulfate mineral of barium, with barium sulfate as its main component.,It has characteristics such as high density, chemical stability, non-magnetic, and non-toxic. The processing and application of barite powder in new fields are of great significance, such as making fabrics tighter, increasing hardness, improving quality and gloss, and reducing production costs in the textile industry. Deep processing of barite, such as ultrafine pulverization, purification, and surface modification, can broaden its application fields and provide better economic benefits..

The role of surface coating modification on barite powder, and the application of "honeycomb grinding" in it.Currently, barite is widely used in drilling mud weighting agents, various barium compounds, zinc barium white pigments, inorganic fillers, cement mineralizers, conductive materials, high-reflective coatings, and other fields. Surface coating modification can improve the performance of barite powder in different applications, such as enhancing hardness, wear resistance, and aging resistance in industries like paints, rubber, and plastics.
