A superheated steam release paper rehumidification equipment with electrostatic field and its manufacturing process

Abstract

The invention discloses a superheated steam release paper rewetting apparatus with an electrostatic field, and a manufacturing technology of the apparatus. The superheated steam release paper rewetting apparatus with an electrostatic field comprises a shell, a paper traversing channel for release paper to traverse through is arranged in the middle portion of the shell, the paper traversing channel divides the shell into two mutually independent steam injection chambers, two sides of the paper traversing channel between the two steam injection chambers are provided with rewetting areas, every steam injection chamber comprises a low pressure area stem area, a high temperature area superheated steam area, a flow guiding area and a steam source control mechanism, and the flow guiding areas are provided with steam injection tubes connected with the rewetting areas; the bottom of the shell is provided with a steam-water separator connected with the high pressure superheated steam area; and the bottom and the top of the shell are respectively provided with guiding rollers used for guiding the release paper, and the guiding roller positioned in the bottom inlet of the shell is provided with a high voltage electric field generating area. The rewetting apparatus with high stability and uniform rewetting can be obtained through the manufacturing technology, avoids obstruction caused by poor water absorption property of materials, and guarantees the flat state of the materials.

Description

technical field [0001] The invention relates to the technical field of rehumidification equipment for release paper, in particular to a rehumidification equipment for superheated steam release paper with an electrostatic field and a manufacturing process thereof. Background technique [0002] Release paper is also called release paper, anti-sticking paper, silicone oil paper. It is a release paper that prevents pressure-sensitive adhesive or prepreg from sticking and protects pressure-sensitive adhesive or prepreg from contamination. Widely used in electronic products, automobile manufacturing (automotive interior pasting, foam tape, automotive circuit wrapping tape, etc.), electrical manufacturing (electrical insulation tape), printing, advertising, trademark identification, food, medical and other fields. The commonly used methods in the production of release paper are water rewetting method and direct steam rewetting method. Among them, the water rehumidification method ...
