Product Information
The specific details for hollow fiber membrane spinning machine of Trustech are mainly reflected in the following aspects.
Core sections of a NIPS production line NIPS
Dope preparation system
Control parameters: dissolution temperature, stirring speed, deaeration time, and vacuum level. Ensure a homogeneous, bubble-free dope to avoid internal fiber defects.
Metering and extrusion systemControl parameters: metering pump flow accuracy, spinneret orifice size and temperature, bore fluid flow rate and pressure. The spinneret orifice directly affects fiber diameter; bore fluid flow must be matched to the dope to prevent fiber collapse.
Coagulation and forming systemControl parameters: coagulation bath temperature, composition, and liquid level; washing temperature and time to avoid fiber shrinkage. Washing must thoroughly remove residual solvent to prevent membrane performance degradation.
Post treatment and take-up system
Control parameters: draw ratio, drying temperature and time, winding tension. The draw ratio should be controlled at 1.5–3× to enhance mechanical properties;drying temperature should be tailored to the material to avoid embrittlement from overdrying.
