    摘要: The present invention provides a production method for a microporous polyolefin resin sheet which enables the stable formation of a sheet having uniform crystallinity, even when the speed of the casting cooling device is high, and has excellent thickness uniformity and appearance grade.
    The production device for a microporous polyolefin resin sheet according to the present invention includes a mouthpiece that extrudes a molten resin in a sheet shape; a casting cooling device that cools and solidifies a sheet extruded from the mouthpiece while conveying the sheet; and a decompression chamber that is installed upstream from the mouthpiece in a conveying direction of the casting cooling device and aspirates air between the sheet extruded from the mouthpiece and the casting cooling device; and further includes a rectifier that is installed and blocks a gap between the sheet discharged from the mouthpiece and the cast surface. The decompression chamber of the production device for a microporous polyolefin resin sheet according to the present invention includes: a sealing member provided in at least a peripheral portion of a surface opposing the casting cooling device and in physical contact with the casting cooling device; and a partition plate provided across a sheet width direction in a vicinity of an opening part opposing the mouthpiece.
