BELT-TYPE APPARATUS FOR CONTINUOUS PLATE FORMATION AND METHOD OF CONTINUOUS PLATE FORMATION WITH BELT

摘要

A belt-type apparatus for continuous plate formation in which a polymerizable raw material is fed to one end of a space surrounded by the opposed surfaces of two endless belts (1) and (1') facing each other and by gaskets (7) disposed at side edges of these belt surfaces so as to be sandwiched between the surfaces, the raw material is polymerized in sections where the belts are heated/cooled with warm water, and a plate-form polymer is taken out of the other end, characterized in that the apparatus has three or more recovery vessels (13) for recovering the warm water used in the heating/cooling and has temperature sensor terminals (thermometers (14)) for measuring the temperature of the recovered warm water in every recovery vessel (13). Also provided is a method of continuous plate formation with belts which comprises using the apparatus to produce a plate-form polymer from a polymerizable raw material comprising methyl methacrylate while measuring the temperature of the recovered warm water with the thermometers (14) in every recovery vessel (13).
