METHOD FOR MANUFACTURING HYDROPHOBIC AEROGEL AND AN APPARATUS THEREOF, CAPABLE OF ACTIVATING A SOLVENT EXCHANGE REACTION BY IRRADIATING ULTRASONIC WAVES AND INPUTTING NITROGEN

摘要

PURPOSE: A method and an apparatus for manufacturing hydrophobic aerogel are provided to economically manufacture the hydrophobic aerogel by promoting a solvent exchange reaction and to easily product the hydrophobic aerogel.;CONSTITUTION: A method for manufacturing hydrophobic aerogel comprises a step of substituting wet gel for an organic solvent and a step of reforming the wet gel to have hydrophobicity through silylation and a drying process. A net-shaped basket is inserted into the inner part of a reactor(100) and the wet gel is inputted into the inner part of the basket. An ultrasonic waves generator(120) is installed on the lower part of the reactor. Nitrogen is injected into the reactor and promotes a reaction.;COPYRIGHT KIPO 2011
