METHOD FOR BELCHING WATER FROM SWOLLEN SUPERABSORBENT POLYMERS AND METHOD FOR RECYCLING SANITARY ABSORBENT ARTICLES USING THE SAME

摘要

The present invention relates to a method for removing water from swollen superabsorbent polymers in a gel state, and a method for recycling sanitary absorbent articles using the same. According to the method of the present invention for removing water from swollen superabsorbent polymers by immersing swollen superabsorbent polymers in a gel state into a composition wherein sea water that is easily available and calcium chloride that is easily available with low cost are mixed, for a specified period of time, it is possible to easily and economically remove water from swollen SAPs in a gel state. Thus, they can be advantageously used in economical and environmentally-friendly recycle of sanitary absorbent articles comprising an absorbent that consists of SAP and cellulose pulp after used for purposes of absorbing human waste.
