Contexto do projeto
O projeto was conducted for a leading domestic Chemical New Material Research Institute, focusing on the high-end application of Silica Surface Modification. The primary goal was to improve the dispersibility of silica in rubber/plastic matrices and achieve high-capacity continuous production.
Industry Challenges
As a reinforcing filler, silica is rich in silanol groups (-OH) on its surface, making it highly hydrophilic and prone to agglomeration. Traditional modification methods often face:
- Inconsistent Coating: Incomplete surface coverage of particles.
- High Energy Consumption: Low efficiency in batch production.
- Dust Pollution: Poor sealing leading to hazardous working environments.
The Solution: Epic Powder CRM Three-Roller Coating Machine
The institute selected the Pó épico CRM Series Three-Roller Continuous Coating Machine, This equipment is specifically designed for advanced Silica Surface Modification using unique mechanochemical principles.
- Model: CRM Series
- Capacidade: 1200 kg/h
- Process: Continuous high-speed rotor impact, shearing, and mixing.
Process Workflow
- Quantitative Feeding: Silica is fed via a screw feeder.
- Agent Atomization: Modification agents (e.g., silane coupling agents) are atomized under high pressure.
- Three-Roller Modification: The material forms a spiral gas-solid flow. High shear forces break down agglomerates, while mechanical energy generates heat to facilitate chemical bonding.
- Collection: The modified powder is captured by a professional filtration system.
Project Outcomes
- Activation Rate: Surface coating coverage exceeds 98%.
- Improved Performance: Significant reduction in oil absorption and superior filler distribution index in rubber compounding.
- Efficiency: Stable 1200kg/h output with 30% lower energy consumption compared to batch processes.
- Eco-friendly: Negative pressure operation ensures a dust-free workshop.
