摘要： Provided are a pitch-formation suppressor and the like which can be widely applied independently of the substance that causes a pitch and of the situation to generate a pitch in a paper manufacturing process, and which can effectively suppress and prevent the troubles due to the pitch, such as foreign spots and defects in a paper, breakage of a paper, and lowering of workability. This pitch-formation suppressor comprises an alkaline solution in which a phenol resin and/or a modified phenol resin is dissolved, or an acid solution in which a phenol resin and/or a modified phenol resin is dissolved.

摘要： The resin-coated sand is produced by coating the surface of a refractory granular aggregate with a thermosetting resin and a thermoplastic resin. When using this resin-coated sand, a mold with a less rough surface can be produced by a RP molding apparatus. When using this mold made of the resin-coated sand, a casting with fewer gas defects can be produced.

摘要： One of the objects of the present invention is to offer novolak type phenolic resins which use phenols and aldehydes as raw materials and give narrow molecular weight distributions.The novolak type phenolic resins of the present invention are those obtained by condensation reaction of phenols with aldehydes in the presence of an oxycarboxylic acid having carboxyl groups, --COOH, and alcoholic hydroxyl groups, --OH, in one molecule. Thus, obtained novolak type phenolic resins show narrow molecular weight distributions, lower viscosity in molten state and, as a consequence, uniformity in curing time.

摘要： An activated and heat-treated product of a pitch fiber (A) is combined with an activated and heat-treated product of a precursor fiber of carbon fiber (B) having a larger elongation and a larger shrinkage during activation treatment thereof than those of the pitch fiber (A) to provide an activated carbon fiber structure. The activated carbon fiber structure is produced by subjecting the pitch fiber (A) and the precursor fiber of carbon fiber (B) to an activation treatment before or after the fibers (A) and (B) are formed into a configuration corresponding to a fiber structure through mixing or laminating.
