Cellulose Sigma Mixer FAQ
1. Uneven reaction, large fluctuations in product substitution degree (DS)?
- High-powered shearing sigma blades: Simulating hand-kneading motions, two differently speed-driven agitator shafts generate extremely strong mutual compression and shearing forces.
- Precision gap control: The gap between the blades and the cylinder is maintained at 2-3mm, Completely eliminating dead zones in the agitation and ensuring full contact between alkali cellulose and the etherifying agent at the molecular level.
2. Inaccurate temperature control can lead to cellulose "charring" or degradation?
- Triple-layer jacket + spool cooling: Not only is the outer wall of the cylinder heated/cooled, but the internal circulation channel of the stirring shaft is also designed to improve heat transfer efficiency.
- Segmented intelligent temperature control: Combined with a high-precision sensor, it responds to the exothermic curve in real time, maintaining temperature control accuracy within ±1°C.
3. Shaft seal leakage (air or liquid), low solvent recovery rate, and failure to meet environmental and safety standards?
- Heavy-duty sealing system: Employs a combination of packing seal and mechanical seal, combined with high-hardness alloy bushings, maintaining high vacuum for extended periods even under strong alkaline corrosion.
- Explosion-proof system: The motor, reducer, and control box all comply with Exd II BT4 standards, supporting fully closed-loop solvent recycling.
4. Difficult to clean, with material adhering heavily to the walls, leading to cross-contamination and wasted labor?
- Mirror-polished cylinder inner wall and blades: The inner liner is made of SS304/316 material, finely polished to Ra < 0.4μm, as smooth as a mirror.
- Hydraulic tilting discharge: The tilting angle can reach 100°, and with the assistance of bottom screw extrusion, the residual rate is reduced to below 0.5%.
