"3. KEY PROBLEM: OVEN HEATED TEFLOND YARNS ARE STIFFER. CAUSED BY "OVERDRYING" WICH HARDENS DISPERSION COATING BY REVOVING RESIDUAL MOISTURE AND SOME TRITONO SURFACTANT (A LIQUID). - THINNER COATING ON KEVLAR IS LESS STIFF. PACKING FAILED INTERNAL TEST: - TEFLOWD WOULD KOT SEAL AT STARTUP - KEVLARD FAILED AT BELOW NORMAL PUMP SPEED. HEATED YARNS DARKENED VIA OXIDATION OF TRITONS. ON-LINE HEATING: MAY BE ROUTE TO ACCEPTABLE PRODUCT. TEST WITH SEMINORKS CRYSTALLIZER ROLLS: - REMOVED FC-143 FROM TEFLON YARN IN 6 SEC. AT 2276C. (40 YPM PROCESS) - PRODUCED YARNS LESS STIFF, LESS DISCOLORED THAN OVEN REATED YARN. VARNS OF KEVLAR AND TEFLON PRODUCED FOR PACKING TEST. LABORATORY RADIANT HEATER REMOVED 94% OF FC-143 IN 4 SEC. WITH 500 OVEN. CONCLUSIONS: CAN ELIMINATE FC-143 VIA HEATING. PACKAGE HEATING IN OVENS DOES NOT APPEAR FEASIBLE. ON-LINE HEATING WITH HOT ROLLS APPEARS FEASIBLE, PENDING SEPT. PACKING TEST. RADIANT HEATING APPEARS HARDER TO CONTROL FOR UNIFORM FC-143 REMOVAL WITHOUT MELTING YARN. 000030 EISDP7R1O502143069 . .o -a- 8. INTERIM PROCESSES - DISPERSION PURIFICATION CONCEPT: SEPARATE FC-143 FROM DISPERSION, AFTER POLYMERIZATION, USING DIALYSIS OR ION EXCHANGE. DIALYSIS (ULTRAFILTRATION) SOLUTION FORCED THROUGH MEMBRANE UNDER PRESSURE: TEFLON PARTICLES RETAINED, FC-143 AND TRITON REMOVED. - FRESH TRITON SOLUTION ADDED TO HATNTAIN CONCENTRATION VENDOR TEST SITE IDENTIFIED (ABCOR) TEST AT ABCOR TO BEGIN APPROXIMATELY 9/1. (DELAY IN COMPLETING NON-LIABILITY CONTRACT) ION EXCHANGE ABSORPTION OF PERFLUOROOCTANOATE ION ON ANION-EXCHANGE RESIN. ~ TEFLON PARTICLES, NONIONIC TRITON HOT RETAINED. CONCEPT TESTED BY PPD IN 1966 - ACHIEVED ONLY 18% FC-143 REMOVAL AND RESIN PLUGGED COLUMN, INITIAL SPRANCE TEST CBTAINED 91% REMOVAL AND GOOD FLOW RATE USING POROUS-BEAD RESIN USED FOR SPRUANCE DEIONIZED WATER. DISPERSION REMAINED STABLE. CONCLUSIONS: PREDICT GOOD CHANCE TO REMOVE FC-143 WITH KO PRODUCT PROBLEMS, USING MULTI-PASS UNITS. ANTICIPATE NO MAJOR PROCESS OR PRODUCT PROBLEMS, OR DELAYS IN SCALING UP WITH COMMERCIAL UNITS, EITHER PURCHASED OR RENTED. EXPECT TO RECOMMEND 10M EXCHANGE SCALEUP IF INITIAL RESULTS CONFIRMED. - FEWER PROCESS AND PRODUCT PROBLENS ~ SHORTEST LEAD TIME TO INSTALL EQUIPHENT - HASKELL TESTING NOT BELIEVED NECESSARY . sPrO01370 EID715241 000041 Lo.
