AI Technical Summary
Technical Problem
Traditional silicon micropowder surface modification treatments suffer from uneven coating and powder agglomeration, resulting in coarse particles.
Method used
An ultrasonic vibrating screener is used for screening, which combines an ultrasonic generator and a transducer to suppress powder adhesion and agglomeration through high-frequency, low-amplitude ultrasonic vibration waves. The powder is then modified by combining a spiral cutter and a mixing device.
Benefits of technology
It achieves uniform coating and reduced agglomeration of modified silica powder, improves sieving efficiency and dispersion performance, and is suitable for the modification of most non-metallic powders.
