PREPARATION OF HOLLOW YARN TYPE MEMBRANE SEPARATION APPARATUS

PURPOSE:To achieve air-tight seal, by cutting the cured layer at the end part of a hollow yarn so as to open the hollow part at the end part thereof and further injecting a sealing curing agent into a case while distributing the same to both end parts of the case before solidifying the same. CONSTITUTION:A case main body 1 is packed with a hollow yarn bundled body 2 so as to respectively protrude both ends thereof from the case. In the next step, a potting process for forming cured layers to both ends of the case is performed but, as a concrete means, a method, wherein a curing agent is injected into the case and moved to both end parts of the case by imparting centrifugal force to the case to be cured at said parts, is desirable. Both ends of the case 1 are covered with sealing caps 7, 7' and the dialysate injection ports 4, 4' of the case 1 are utilized as curing agent injection ports while centrifugal force is imparted to the case 1 while the sealing curing agent is injected and moved to both ends of the case.
