Product details of the hollow fiber membrane manufacturers
Product Introduction
The source of raw materials: before Trustech hollow fiber membrane manufacturers comes out, it is processed from high quality raw materials. These materials are sourced from several different places within and out of the region. The product performance is fine, the quality is stable and reliable. Our products add value to customers' business at home and abroad.
Core sections of a NIPS production line NIPS
Control parameters: dissolution temperature, stirring speed, deaeration time, and vacuum level. Ensure a homogeneous, bubble-free dope to avoid internal fiber defects.
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.
