Regenerated cellulose dialysis membrane - for artificial kidneys

摘要

Regenerater cellulose dialysis membrane is made by spinning a viscose containing 5-6% cellulose through annular nozzles into a coagulating bath containing 5-20% H2SO4, 10-20% Na2SO4 and 0-15% (NH4)2SO4, and plasticised with glycerol and/or sorbitol. The viscose contains, as additional plasticiser, 0.1-10% calc. on cellulose of a silicone oil. Flexibility combined with ultrafiltration properties, strength and resistance to bursting. Dialysis membranes for artificial kidneys.
