| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF OSMOSIS REVERSE MEMBRANES |
| abstract | PROCEDURE TO PREPARE REVERSE OSMOSIS MEMBRANES. INCLUDES: A) MOLDING ON A SUPPORT AND BETWEEN 0J AND 125ยบ C A SOLUTION OF AROMATIC POLYAMIDE, TO FORM A PRE-MEMBRANE; B) DRY THE PRE-MEMBRANE BETWEEN 50J AND 170JC, TO REDUCE THE POLYMER OF SAID PRE-MEMBRANE BY 30 TO 50% BY WEIGHT; C) TEMPER THE DRIED PRE-MEMBRANE WITH WATER, BETWEEN 0J AND 30JC AND FOR 0 TO 10 SEC, TO ELIMINATE THE RESIDUAL SOLVENT FROM THE POLYAMIDE AND GELL THE POLYMER; AND D) ANNEALING THE PRE-MEMBRANE IN AQUEOUS BATHS BETWEEN 40JC AND 400JC, TO OBTAIN MEMBRANES WITH THICKNESS BETWEEN 25 M AND 250 M. THE AROMATIC POLYAMIDE SOLUTION CONTAINS FROM 10 TO 30% BY WEIGHT OF AROMATIC POLYAMIDE AND FROM 20 TO 60% IN WEIGHT REFERRED TO THE POLYAMIDE OF A SALTS CHOSEN FROM LITHIUM NITRATE, HYDRATED MAGNESIUM CHLORIDE AND MIXTURES THEREOF. |
