Vacuum kneading-and-defoaming device

Abstract

Provided is a vacuum kneading-and-defoaming device that can subject a paste material contained in a cylindrical paste container to uniform and sufficient kneading and to sufficient and highly efficient defoaming. The disclosed vacuum kneading-and-defoaming device includes: a revolution-purpose rotary element that is provided inside a chamber to be brought into a decompressed state, and that rotates within a horizontal plane about a reference drive rotation axis; a container retaining means that is provided on the orbiting edge of the revolution-purpose rotary element in a manner so as to be spinnable about an operation rotation axis which is parallel to the reference drive rotation axis, and that detachably retains a paste container in a state such that the central axis of the paste container obliquely intersects with the operation rotation axis; and a drive mechanism that rotates the revolution-purpose rotary element and the container retaining means. An opening provided in the paste container for the introduction of a paste material has: a degassing valve that opens the interior space of the paste container to the interior space of the chamber by the action of centrifugal force caused by the revolution and the spinning of the paste container; or a gas-permeable membrane that is impermeable to the paste material.

Description

technical field

[0001] The invention relates to a vacuum kneading and defoaming device. Background technique

[0002] For example, medical paste materials such as paste materials used as sealants for liquid crystals and semiconductor elements, conductor paste materials, resistor paste materials, or compound pastes for rubbing medicines need to be fully kneaded, It is used in a defoamed state. In such a paste material, for example, at least two or more liquids with high viscosity and different specific gravity values, or liquids and powders with different specific gravity are required to be uniformly mixed and dispersed.

[0003] Currently, various types of kneading and defoaming devices for kneading and defoaming paste materials have been proposed. For example, someone has proposed a scheme of the following structure: the container holding body, for example, a cup-shaped paste container that holds the paste material to be kneaded in a detachable manner, revolves around a re...
