PES hollow fiber membrane unstable drawing
ظاهرة المشكلة
Uneven wall thickness or broken filaments occur in hollow fiber membrane spinning
تحليل الأسباب
The spinning solution (casting solution) composition does not match; coagulation bath temperature and composition fluctuate; draw ratio set improperly
الحل
Optimize the polymer content and additive formulation of the spinning solution; precisely control the coagulation bath conditions; adjust the draw ratio within a suitable range
الخلاصة الأساسية
The PES hollow fiber membrane manufacturing process is high-precision process control
