| titleOfInvention | Management method of impregnated resin |
| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: To quickly and accurately determine the availability of an acid anhydride composed of a curing agent for an epoxy resin and an acid anhydride and the useful life of the impregnated resin. To provide a resin management method, eliminate delay of resin impregnation process, and enable effective use of impregnated resin. SOLUTION: The amount of a free acid that accelerates a polymerization reaction with an epoxy resin in an acid anhydride is measured by an infrared spectrophotometer 9 at a wavelength of 17 The absorbance A 1 corresponding to 75 cm −1 was determined, and the absorbance A of the sample in which the concentration M of the free acid of the acid anhydride previously hydrolyzed with distilled water was changed was measured. The concentration M 1 is determined, and this value is compared with the reference value to determine whether or not the acid anhydride can be used. |
