发明名称 Apparatus for impregnation of porous samples for materials evaluation
摘要 An apparatus for impregnating porous samples for materials evaluation with an inert material which fills the pores of the samples. A plurality of samples are placed in mold cups on a rotatable table within a vacuum chamber, and a supply of impregnant or encapsulant material such as an epoxy resin is provided in a container mounted on a tiltable platform located above the rotatable table. A plurality of samples are thus mounted in respective molding cups spaced in a circle on the rotatable table, a supply of encapsulant material is provided in a cup placed in a cup holder on the tiltable platform, a vacuum is created within the chamber, and the table is intermittently rotated to position each molding cup with its sample in line with the tilt axis of the tiltable platform to permit tilting of the encapsulant cup to pour a supply of resin into the molding cup. The foregoing procedure is repeated until each of the molding cups has received a desired supply of the resin material, while the vacuum is maintained within the chamber.
