MANUFACTURING METHOD OF HYDROPHILIC NaA ZEOLITE NANO-PARTICLES CAPABLE OF INCREASING HYDROPHILIC PROPERTIES AND MECHANICAL STRENGTH OF POLYELECTROLYTE SEPARATION FILMS

摘要

PURPOSE: A manufacturing method of hydrophilic NaA zeolite nano-particles is provided to enhance dispersibility between particles and to obtain uniformity of particle sizes.;CONSTITUTION: A manufacturing method of hydrophilic NaA zeolite nano-particles comprises the following steps: manufacturing a solution I by including 40-60 wt% of silica sol and 40-60 wt% of distilled water based on the total weight of the solution I; manufacturing a solution II by including 5-7 wt% of Al (OiPr), 30-40 wt% of tetramethyl ammonium hydroxide 5 hydrate (TMAOH5H2O), 3-5 wt% of 1M NaOH and 50-60 wt% of H2O based on the total weight of the solution II; agitating the solution I and solution II by mixing at the weight ratio of 1:2-1:5 at room temperature for 12 hours-10 days; and agitating the mixture of the solution I and II in a 60-100 deg. Celsius thermo-bath for 5 hours-3 days.;COPYRIGHT KIPO 2013
