摘要: The present invention relates to a method of removing a layer of material from a synthetic resin or an organic acid ester of cellulose comprising: washing the layer from the substrate with an aqueous alkali solution with a temperature of at least 105° C., and then washing the alkali solution from the substrate. Furthermore, the present invention relates to a pressure vessel used for the above method, comprising a longitudinal cylindrical body having a circular cross-section, an end plate connected to the top of the cylindrical body and an inverted end plate connected to the lower part of the cylindrical body in a manner such that its convex part faces upwards wherein the pressure vessel has a strainer plate and a stirring blade inside the cylindrical body.
