PURPOSE: To contrive prevention of accidental explosion, by heating and kneading an article to be obtained by loading a neutralizer having an acid gas discharge function to a cellulose series crushed aggregate.
CONSTITUTION: A cellulose series aggregate (a) is dried so that dryness of the same falls within 5% and made into fine powder. Neutralizer sucking and discharging acid gas according to a temperature change such as mono ethanolamine or triethanolamine is mixed with the crushed powder aggregate (a), which is heated and kneaded. The circumferential surface of the aggregate (a) is kept curing gradually according to kneading of the aggregate (a), solidified state is exhibited by tying together a hairy part (a') of fabric which has existed on the circumferential surface of the aggregate (a), the surface of the aggregate (a) molded becomes smooth, moreover, there is no room to swell by containing water, lubricity is favorable and nonhygroscopicity is brought to the aggregate (a). Based on the above matter, danger of accidental explosion hardly occurs, and molding of a large quantity of aggregates (a) becomes possible continuously.
