发明名称 METHOD AND APPARATUS FOR ALKALI SAPONIFICATION OF POLYMER FILM
摘要 <P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for the alkali saponification of a polymer film which enables high precision control of saponification treatment reaction even at an increased carrying rate. <P>SOLUTION: The alkali saponification apparatus 10 has a coating process section 14 for coating an alkali solution on a polymer film 12, a reaction process section 16 for effecting saponification reaction of the coated alkali solution, and a reaction termination process section 18 for terminating the saponification reaction. The reaction process section 16 is surrounded with a casing 20, and the casing 20 is connected to an air supply line 24 on which a humidifier 28 is disposed. <P>COPYRIGHT: (C)2008,JPO&INPIT
