DEGRADABLE VERTICAL DRAIN BOARD IN WHICH A MACROMOLECULE SYNTHESIS TECHNOLOGY IS APPLIED USING ENVIRONMENT-FRIENDLY RESOLVENT POLYESTER RESIN

摘要

PURPOSE: A degradable vertical drain board in which a macromolecule synthesis technology is applied is provided to prevent environmental contamination by using a biodegradable polyester resin. CONSTITUTION: A degradable vertical drain board comprises a core and a filter. The core is a pressed body which is made of freshly synthesized polyester resin as the main component. The core has a plurality of water paths. The filter surrounds the core. A core material contains α-cyclodextrin and adipic acid(9).
