ELECTRODEPOSITION OF POLYMER

摘要

PURPOSE: To produce a thick and flexible tree fixing film by employing at least one sleeve electrode coaxially spaced apart from and surrounding at least one other electrode in a bath comprising a dispersion of electrically charged thermoplastic film forming polymer particles in an organic liquid dispersion medium. CONSTITUTION: A belt forming sleeve mandrel electrode is placed in a container and a counter electrode having center on the inside of the belt forming sleeve mandrel electrode is placed coaxially with the mandrel over the entire length thereof. An output source is connected on the negative side with the belt forming sleeve mandrel electrode as a cathode and connected on the positive side with a metal or graphite rod as an anode. Electrodeposition is conducted with a specified applying voltage at the ambient temperature for a specified time and then the belt forming sleeve mandrel electrode having inner surface subjected to electrodeposition coating is taken out from the container and placed in an oven at a temperature and for a time sufficient for aggregate polymer particles into a uniform viscous sol layer and removing solvent by evaporation.
