Abstract:
An active material coating apparatus forms an active material layer having a uniform thickness across the width of a substrate. The active material coating apparatus includes a lower die having a groove for supplying an active material of a slurry state and forming a first lip portion of an outlet slot connected to the groove and outputting the active material; an upper die disposed on an upper side of the lower die to face the first lip portion, having a second lip portion of the outlet slot, and having a hinge portion at the rear of the second lip portion according to the outlet direction of the active material; a fixing spacer interposed between the lower die and the upper die at the rear of the hinge portion according to the outlet direction of the active material and determining a fixing gap; a flexible spacer interposed between the first lip portion and the second lip portion on both sides of the width direction of the outlet slot and forming a variable gap; and a controller installed to the upper die and pushing/pulling the second lip portion with respect to the hinge portion to control the variable gap between the first lip portion and the second lip portion.

PROBLEM TO BE SOLVED: To provide a method for producing a laminated film, which is capable of preventing a coating liquid from being mixed with each other, when applying wet-on-wet multilayer coating of the coating liquid containing an organic solvent.SOLUTION: The method for producing the laminated film includes: a step of preparing a first coating liquid 11 containing a first organic solvent in which particles 1a having a first charge are dispersed and a second coating liquid 12 containing a second organic solvent in which a binder 2a having a second charge opposite to the first charge is dispersed; and a step of forming a second coating film 14 and a first coating film 13 by applying the wet-on-wet multilayer coating on one surface of a running support 3 and forming a gelled layer 50 by gelating the particles 1a and the binder 2a using neutralization between the charges. Thus, the method can prevent the first coating liquid 11 and the second coating liquid 12 from being mixed with each other.

PROBLEM TO BE SOLVED: To provide an extrusion coating device which can control a coating shape of the edge regardless of a coating thickness and can suppress generation of a high edge. SOLUTION: The extrusion coating device has coating width regulating plates 24 inserted into both edges of a slit 16, a slit die 10 for discharging a coating liquid from a discharge port 16A of the slit 16, and a chamber 26 for depressurizing the upstream side in a web running direction. The coating width regulating plate 24 is provided with a projection 24A bent toward the web downstream side and facing a web. The coating liquid is applied to the web in a state where the coating liquid is oozed on a web facing surface of the projection 24 of the coating width regulating plate 24 by the depressurization by the chamber 26.

Abstract:
PROBLEM TO BE SOLVED: To provide a process for producing a long laminated film by which, when a coating layer is formed by pressing a coating head against a surface of a long film running on two supporting guide rollers to apply a paint thereon, stripe-like irregularity in the coating layer is not caused.SOLUTION: The long film 11 is nipped and driven by a pair of nip rollers 16, 17 and a second guide roller 13 at both breadth-direction edge portions 11c of the long film 11. The pair of the nip rollers 16, 17 is disposed in a truncated chevron shape: the rotation axes 16a, 17a thereof intersect at an intersection point 18 at the downstream side of the running direction 15 of the long film 11. Thereby, a force 19 is applied to the long film 11 in the breadth direction, not only the force in the film running direction 15. The force 19 in the breadth direction works to broaden the long film 11. The force 19 applied in the breadth direction eliminates wrinkles in the long film 11.
Abstract:
PURPOSE: To perform the formation of a nonaqueous multilayered coating film at a low cost, by forming one out of the coating layers from a composition containing electron-curing resin, and holding the viscosity of one layer above a specified value. CONSTITUTION: At least one out of two or more coating layers is made of a composition containing electron-curing resin, while at least one out of two or more coating layers is made of a coating material having viscosity of 100cps or higher. After two or more coating layers are laminately applied, the obtd. coating film is cured or made viscous by electron irradiation and then dried. Hence, the formation of a nonaqueous multilayered coating film can be performed at an extremely low cost. COPYRIGHT: (C)1984,JPO&Japio
Abstract:
A method of dispensing a metallic nanoparticle composition along a trajectory on a substrate is disclosed. The composition is dispensed from a nozzle through its outlet. The outlet is characterized by an outlet size. First, an initial pressure is applied to the composition in the nozzle to cause the composition to flow from the outlet. The nozzle is positioned at a height such that the composition does not flow onto the substrate. Second, the nozzle is lowered toward the substrate such that a fluid bridge forms between the outlet and the substrate and an adjusted pressure is applied to the composition in the nozzle. The adjusted pressure is lower than needed for the composition to continue to flow from the outlet. Third, the fluid is dispensed from the nozzle. A dispensing pressure is applied to the fluid while the nozzle is laterally displaced along the trajectory on the substrate.
