摘要:
Ceramic fiber molding for manifold reactors in which Al.sub.2 O.sub.3 --SiO.sub.2 ceramic fibers or SiO.sub.2 ceramic fibers are employed to form a molded product having a hardness of 20.degree. - 55.degree., a tensile strength of 120 - 1500 g/cm.sup.2 and a molded density of 0.06 - 0.35 g/cm.sup.3.
摘要:
A DI forming water-based coolant of a laminated metal sheet includes at least one kind of base (a) selected from alkanolamines and alkali metal hydroxides, a fatty acid (b), and water (c), wherein the total content of the base (a) and the fatty acid (b) is 0.02 to 4% by mass and the ratio of a straight-chain fatty acid having a carbon number of 6 to 12 in the fatty acid (b) is 80 to 100% by mass.
