Advanced Membrane Manufacturing Apparatus for Hollow Fibers

Overview

• Automated Mixing: Polymer solutions are uniformly mixed under controlled temperature and pressure conditions to ensure homogeneity.
• Precision Pumping: Continuous stirring and controlled pumping to the spinneret ensure consistent fiber formation.
• Pressure Control: High-pressure tanks (up to 100 psi) maintain stable operating conditions for solution delivery.
• Integrated Coagulation System: Fibers enter a temperature-controlled coagulation bath immediately after extrusion to induce phase inversion and structural formation.
• Flow Regulation: Pneumatic flow controllers enable precise adjustment of polymer and bore fluid flow rates.
• Post-Processing Unit: Includes washing tanks and a collection drum for proper cleaning and handling of the fabricated hollow fibers.
• Advanced Research Platform: The system is designed for high accuracy, repeatability, and ease of operation, making it suitable for both academic and industrial R&D applications.
• Process Flow: Hollow fiber fabrication begins with polymer solutions prepared and maintained in pressure vessels under controlled temperature conditions.
• Fiber Formation: The polymer solution is extruded through a specialized spinneret, forming hollow fibers via phase inversion mechanisms.
• Immediate Stabilization: The nascent fibers pass through a coagulation bath, where solvent–non-solvent exchange solidifies the membrane structure before washing and collection.
• Customizable Performance: Key parameters such as flow rate, temperature, and composition can be adjusted to achieve desired pore size, porosity, and morphology. The resulting membrane characteristics can be validated using techniques such as liquid–liquid porometry.
