摘要
研究了聚偏氟乙烯中空纤维膜成膜机理，采用高分子添加剂、表面活性剂、非溶剂三者混合复配成纺丝添加剂，可以得到高功能聚偏氟乙烯中空纤维多孔膜。
The membrane formed with PVDF hollow fibre was spinned. The poor forming agent was prepared with three reagents; polymer, surfactant and nonsolvent. The PVDF solid content in spinning solution is about 15-25wt%. The dry spinning distance must be ≤30 cm and spinning speed≤20m/min for inner fibre. The dry spinning distance must be≤10 cm and the spinning speed nay be 20-60m/min for outer fibre.
