Innovative solution for mixing high viscosity and complex system materials

In today's world of continuous innovation in material processing technology, the uniformity of mixing in complex systems with high viscosity and multiple components remains a core challenge in industrial production. As a professional manufacturer of vacuum planetary centrifugal mixers, SMIDA has 15 years of technological accumulation, deeply integrating planetary motion with centrifugal force fields and vacuum environments, providing disruptive hybrid solutions for fields such as electronics, new energy, and aerospace. Compared to traditional mixers, SMIDA equipment exhibits more than three times the efficiency improvement and precision breakthrough in high viscosity materials and solid-liquid multi systems ranging from 100000 to 1 million cP.
​

The core advantage of SMIDA devices lies in the innovative integration of three major technological modules:
Composite motion flow field: The stirred container forms a planetary trajectory through revolution and rotation, coupled with a 45 ° inclined design, generating a triple effect of radial shear force (crushing agglomerated particles), axial convection (material flipping), and tangential infiltration (mixing materials with density differences) inside the container. ​
Vacuum defoaming system: The vacuum negative pressure environment and centrifugal force work together, causing bubbles to migrate towards the edge of the container under mechanical effects. Combined with gravity design, the bubble rate of semiconductor packaging adhesive is reduced from 5% in traditional processes to below 0.1%, meeting the reliability requirements of automotive standards. ​
Intelligent temperature control module: a circulating circuit temperature control system that solves the performance degradation problem caused by high viscosity material stirring and heat generation. After being used by a lithium battery enterprise, the viscosity stability of silicon-based negative electrode slurry increased by 40%. ​

Exemplary treatment of high viscosity materials
In the field of electronic pastes, SMIDA stirring equipment has shortened the traditional stirring process from 45 minutes to 12 minutes for conductive silver paste (viscosity of 800000 cP), photovoltaic silver aluminum paste and other systems, and improved the dispersion uniformity of silver powder to 99.3%. According to data from a TOP5 photovoltaic company, the use of this equipment has resulted in a 25% increase in the consistency of the welding tension of the solar cells. ​
Breakthrough in Complex System Mixing
For multiphase systems such as metal based composite materials (such as SiC particles/aluminum alloy liquid-solid mixtures) and nano catalyst slurries, the three-dimensional flow field of the equipment can overcome the stratification problem caused by density differences. The vacuum stirring system customized by a certain aerospace materials research institute has achieved non segregation mixing of carbon fiber (density 1.7g/cm ³) and epoxy resin (density 1.2g/cm ³), and the compliance rate of composite material tensile strength has increased from 78% to 96%. ​
