Abstract:
Processes and devices useful in the application of coatings (14) to the interior of tubes (10) are described. Such processes (40, 400) may include applying a layer (20) of coating fluid (18) to the internal surface (16) of the tube (10) and passing a smoothing member (22) through the tube (10) at a distance from the internal surface (16). The viscosity of the coating fluid (18) may be selected so that the layer (20) of coating fluid (18) has a thickness substantially equal to or in excess of a predetermined wet film thickness (Twf) correlated to a desired final thickness (Tf) of the coating (14). The distance between the smoothing member (22) and the internal surface (16) may substantially correspond to the predetermined wet film thickness (Twf). The smoothing member (22) may smooth the coating fluid (18) and remove coating fluid (18) in excess of the wet film thickness (Twf) from the internal surface (16).
Abstract:
Disclosed herein is an apparatus for coating a substrate, including a horizontal coating unit having an inlet and an outlet through which a substrate is moving in and out horizontally, and coating surfaces of the substrate with coating liquid by horizontal dipping method to form a protective layer; and a squeegee unit arranged outside the outlet of the horizontal coating unit and being in close contact with the protective layer of the substrate moving out of the horizontal coating unit through the outlet to uniformize coating thickness of the protective layer.According to the present invention, coating thickness of a protective layer coated on a substrate is formed uniformly, and in particular coating quality of edges of the substrate is improved. Therefore, it is possible to minimize foreign substances introduced during manufacturing process of the substrate, thereby reducing defective rate due to foreign substances and improving productivity.
Abstract:
Disclosed are a battery electrode manufacturing method and a battery electrode manufacturing device which improve yield in the battery electrode manufacture. The disclosed method for manufacturing battery electrode involves coating a transported current collector sheet with an electrode paste. A reduced-pressure chamber is arranged at the tip of a die where the aforementioned electrode paste is discharged, and the coating width of the aforementioned paste is controlled by changing the pressure of the aforementioned reduced-pressure chamber.
Abstract:
A method for improving the appearance of a hard-surfaced floor. The method includes selecting a tinted coating comprising a base component and at least one colorant wherein the colorant is selected from the group consisting of a tint, a dye, and a pigment; applying the tinted coating to a topcoat on a top surface of the hard-surfaced floor; and urging the tinted coating into any scratches in the hard-surfaced floor.
Abstract:
An imprint method includes, in the peeling step of peeling a mold off the material layer to be transferred, a region-of-contact recognition operation of recognizing and determining a region of contact of the mold with the material layer to be transferred, a center-of-gravity locating operation of determining a center of gravity of a morphology of the thus recognized region of contact on the basis of that morphology, and a peeling operation of determining a point of force for applying peeling force to the mold or the imprinting substrate in relation to the center of gravity determined by the center-of-gravity locating operation, thereby acting the peeling force on the point of force.

The present teachings provide a composition that includes fluoroelastomer particles, core-shell particles wherein the core is a conductive particle and the shell is a fluoroplastic, and a solvent. A surface layer formed from the coating composition is provided.
Abstract:
The present disclosure features processes and equipment for forming a variety of textured materials, including both release webs, and finished products such as flooring materials, wall coverings, textured laminates and the like. The processes described herein allow curing radiation to be passed through a texturing medium, rather than through the substrate to which the curable material is applied.
Abstract:
An electrode mixture paste (5) is applied on both sides of a strip of core material (1) made of porous metal sheet that is running along its lengthwise direction. The paste-coated core material (1) is pressed with press rollers (15a, 15b) alternately from opposite sides once or more, after which the paste-coated core material (1) is passed through the gap between a pair of scraper tools (16a, 16b) to adjust the coating thickness of the paste (5), while the position of the core material (1) is restricted with comb-shaped projections (17a or 17a, 17b), so that, even though the projections (17a, 17b) are distanced from each other sufficiently to allow weld points of the core material (1) to pass through, the coating thickness is precisely regulated. Therefore, a method of applying an electrode mixture paste is realized, with which coating thickness is precisely adjusted and, even in a continuous production process in which core materials are connected together by welding, production failures due to weld points being stuck are prevented.
Abstract:
A process for making a faux finish with a two-part reactive system of materials includes providing a base material liquid of Poly Vinyl Acetate resin and water mixed with a dry powder functional filler and adding an activator liquid to the base material liquid. The activating liquid is a mixture of water and muriate of potash or boric acid product.
Abstract:
Disclosed is a method for producing regularly arranged nanowires from a nanowire-forming material on a substrate. Said method is characterized by the following steps: a) the material is introduced into a carrier liquid at a load remaining at least three orders of magnitude below the loading capacity of the carrier liquid; b) a guiding member is placed on the substrate; c) the substrate is heated to a temperature at which a thin film of the carrier liquid undergoes spinodal decrosslinking on the substrate; d) a film of the carrier liquid that is loaded with material is applied to the heated substrate in the surroundings of the guiding member, where a gradient of the average film thickness is obtained perpendicular to the contour of the guiding member; and e) the carrier liquid is evaporated such that the material is left along lines extending perpendicular to the gradient of the film thickness.
