A Flat Sheet Membrane Casting System mainly consists of four core sections: dope preparation and delivery system, doctor-blade/casting system, phase inversion and solidification system, and post-treatment and winding system. The flat sheet membrane casting equipment performance and stability determine the quality and properties of the flat sheet membrane.
TIPS (thermally induced phase separation) hollow fiber membrane spinning is a technique for producing microporous membranes via temperature change. The core principle is to dissolve a polymer at high temperature in a high boiling, low volatility solvent to form a homogeneous solution, then extrude it through a spinneret. During cooling after extrusion, the system undergoes liquid-liquid or solid-liquid phase separation, ultimately solidifying to form a polymer rich phase and a solvent rich phase. Subsequent extraction removes the solvent; the space previously occupied by the solvent rich phase becomes the membrane's microporous structure.
NIPS hollow fiber membrane spinning is a process for preparing hollow fiber membranes via non-solvent induced phase separation (NIPS). The core principle is to extrude a polymer dope through a spinneret into a non-solvent coagulation bath, where solvent/non-solvent exchange drives polymer phase separation and solidification, forming a hollow structure with an asymmetric porous morphology. This process is widely used in water treatment, gas separation, and medical applications.
Melt Extrusion Spinneret, also called melt Spinning Spinnerette is a core precision component in melt-spinning processes. It forces high temperature polymer melts (e.g., PET polyester, PP polypropylene, PA nylon, PI polyimide) through micro-fabricated orifices under high pressure,typically with diameters from tens of micrometers up to a few millimeters,to uniformly extrude continuous filaments, fibers, or films. Its design must address three key challenges: uniform distribution of the high temperature melt, precise shaping and control, and resistance to corrosion and wear.
