Doctor-blade/casting system
This is the core film-forming section. Key equipment includes the doctor blade or extrusion die. Precisely control blade gap height, blade-to-substrate angle, and the tension of the nonwoven substrate.

Phase inversion and solidification system
Depending on the process, this is either a coagulation bath for NIPS or a cooling zone for TIPS. Strictly control coagulation bath temperature and chemical composition (for NIPS), or the cooling zone temperature gradient and air velocity (for TIPS). These parameters govern phase-separation kinetics and directly determine the membrane's micro-pore structure, surface pore size, and porosity.

Post-treatment and winding system
Mainly includes washing tanks and a winder. Control wash-water purity, temperature, and number of stages to thoroughly remove solvent, and precisely control winding tension and speed to prevent wrinkling or stretching, ensuring flatness and mechanical integrity of the final product.

FAQ

1
What is flat sheet casting process?
Flat sheet membrane spinning typically refers to forming a uniform liquid film of polymer solution on a continuously running substrate such as nonwoven fabric or a rotating drum via casting or doctor-blade coating, followed by phase separation (e.g., NIPS or TIPS) to solidify into a porous separation membrane. This is an efficient, continuous manufacturing method for flat sheet membranes.
