Title:
CENTRIFUGAL TYPE THIN FILM EVAPORATOR AND METHOD FOR MANUFACTURING ALICYCLIC STRUCTURE-CONTAINING POLYMER FOR OPTICAL MATERIAL
Document Type and Number:
Japanese Patent JP2018069194
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a centrifugal type thin film evaporator which can suppress occurrence of economic leakage.SOLUTION: Between opposite faces (30a, 40a) of two flange parts (30, 40) of a flange joint structure part (20) which are opposite to each other, a first volute gasket (50) and a second volute gasket (60), which seal between the opposite faces, are provided in the state of being compressed by the opposite faces. A supply path (70) for supplying an inert gas is provided between the first and second volute gaskets in the opposite faces. Between the first and second volute gaskets, a ring-shaped adapter member (90), of which an inner peripheral surface is so located as to be separated from an outer peripheral surface of the first volute gasket by only a prescribed dimension, is provided in the state that the first volute gasket is not compressed by the opposite faces.SELECTED DRAWING: Figure 2
