    摘要: A method of slot extrusion coating is provided that can be used to apply thin coatings using liquid compositions having high percent solids. A window of operability advantageously identifies the limits of a process to provide these thin high solids coatings. The window of operability is determined by obtaining a first graphical curve representing actual values of wet thickness as a function of percent solids level. The critical wet thickness is then identified on the first graphical curve. The window of operability is identified as an area defined by the boundaries: percent solids greater than the point at which critical wet thickness occurs, an actual wet thickness greater than all points above the first graphical curve and equal to or less than the critical thickness.

    摘要: A method and apparatus for continuously coating moving web and splices with a coating fluid. The system includes a slide coating die having a slide surface with at least one feed slot for extruding the coating fluid onto the moving web. The slide coating die defines a coating gap with the moving web. The coating gap is adjustable between a coating position and a splice coating position. A web guide is positioned to guide the moving web in a first direction past the slide coating die such that a coating bead of the coating fluid can be formed in the coating gap. A vacuum system is positioned to generate a reduced pressure condition along a lower surface of the slide coating die. The vacuum system defines a vacuum gap with the moving web. The vacuum gap is adjustable independent of the coating gap between a coating position and a splice coating position. A detector signals an increase in web thickness. A controller is functionally connected to the detector. The controller adjusts the coating gap and the vacuum gap to the splice coating position in response to an increase in web thickness in excess of a predetermined magnitude while maintaining a stable coating bead.

    摘要: A method and apparatus for coating a moving web with a coating fluid. The coating die has at least one feed slot for supplying the coating fluid to the moving web and a front face demarked from the at least one feed slot by a die edge. A guide mechanism guides the moving web in a first direction past the coating die such that a coating bead is formed in a gap between the moving web and the die edge. The spraying system sprays a cleaning fluid on at least a portion of the front face of the slide coating die such that the coating bead forms a substantially linear static wetting line on the front face of the coating die.

    摘要: The coater apparatus enclosure encloses the entire die of a coating apparatus includes an enclosure structure, a saturation station which saturates a supply gas with solvent, a device which supplies solvent-saturated gas to the enclosure to continuously purge the enclosure, and a device which controls the gas flow to the enclosure. The saturation station could include a heated jacketed vessel and a porous metal bubbler, or it could include a series of heat exchangers. No streaks can form due to coating fluid drying on the die lip because the gas supplied to the die enclosure is saturated with the solvent.

    摘要: An apparatus and method for evaporating a coating solvent from a coating on a substrate and for minimizing the formation of mottle. The coating is heated with a first drying gas at no higher than a first heat transfer rate. The first heat transfer rate is created by a first heat transfer coefficient and a first temperature difference between the first coating temperature and the first drying gas temperature. The first heat transfer rate causes maximum evaporation of the coating solvent yet insignificant formation of mottle when the coating is at the first coating thickness and the first coating viscosity.

    摘要: The present invention provides an enclosure for a coating apparatus, the coating apparatus being of the type comprising a coater face adapted for the flow of a fluid thereover. The fluid flows over the coater face in the form of a film having one or more edges contacting the coating apparatus at one or more "edge contact surfaces." The enclosure defines a partially enclosed space above one or more of the edge contact surfaces. The atmosphere within the partially enclosed space can be at least partially saturated with solvent vapor to prevent or inhibit drying of coating fluid at the edge contact surfaces. Also, the enclosure has a shape that allows visibility of and access to a substantial portion of the coater face of the coating apparatus.
