PTFE Microporous Membrane Ntau Lawm Kab

Qhov ntxeem tau PTFE hollow fiber membrane yog npaj los ntawm extrusion-stretching txoj kev, thiab cov txheej txheem kev npaj muaj xws li compounding, extrusion spinning, uniaxial stretching thiab sintering.Cov khoom sib xyaw ua ke ntawm polytetrafluoroethylene yog pre-pressed ntawm lub tshuab compacting los tsim ib lub cylindrical dawb paug.Lub preformed dawb paug yog extruded thiab spun ntawm 40-100 ° C.Tom qab degreasing thiab kub-txias, ib tug polytetrafluoroethylene hollow fiber membrane tau txais.Lub degreasing kub yog 200-340 ℃, lub tshav kub qhov chaw kub yog 330-400 ℃, thiab lub sij hawm kub yog 45-500s.Lub microscopic morphology yog kwv yees li ncig (elliptical lossis ncig) pore qauv.
