    摘要: Disclosed is a liquid epoxy resin composition comprising (A) a liquid epoxy resin, (B) a dimethylpolysiloxane having epoxy groups at its both ends, and (C) a dispersing agent comprising the reaction product of (C-1) a dimethylpolysiloxane having amino groups or carboxyl groups reactive with epoxy resins at its side chains or both ends and having phenyl groups or polyether groups for improving its compatibility with epoxy resins at its side chains, and (C-2) an epoxy resin having the same structure as the component (A). The composition has a reduced internal stress, while maintaining the heat resistance intrinsic to epoxy resins, and has excellent resistance, crack resistance and heat shock resistance.

    摘要: A system for denitrating a starting nitric acid solution by irradiation of microwaves to obtain oxide product of the solution comprises a receiver for receiving the solution, a rectangular oven vessel provided with a bottom plate on which the receiver is put, and a conveying mechanism located below the bottom plate for continuously conveying the receiver on the bottom plate throughout the oven vessel. A microwave generator is operatively connected to the oven vessel for generating microwaves to irradiate the content of the receiver when it passes throughout the oven vessel. The receiver may be rotated and vertically moved when it is subjected to denitration and calcination in the oven vessel.
