Abstract:
Disclosed are ink compositions for printing patterns on substrates having non-stick fluororesin coatings. The ink compositions are particularly useful for printing decorative patterns or markings on cookware or bakeware to provide aesthetic and/or functional effects. Also disclosed are coated substrates which comprise non-stick coatings having patterns. Further disclosed are methods of manufacturing the coated substrates comprising non-stick coatings having patterns.
Abstract:
A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder (10) is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section (12) of the modified planetary roller extruder (10), conveying the raw materials from the feeding section (12) to a compounding section (14) of the modified planetary roller extruder (10), continuously mixing the primary raw materials in the compounding section (14) to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material. The compounding section (14) of the modified planetary roller extruder (10) includes a main spindle (26) surrounded by and intermeshed with a plurality of planetary spindles (28, 30) at least one of which is a double transversal mixing spindle having a plurality of back-cut helical flights.
Abstract:
The present application relates to processes for changing the composition of surfaces and the application of such processes. The process involves the introduction of a surface augmentation composition within an aerosol formed from a liquid precursor with bombarding particles in an ultrasonic shot peening apparatus.
Abstract:
In order to obtain a cold rolled steel sheet having excellent press formability, a cold rolled steel sheet has, on a surface thereof, an organic-inorganic composite film containing: an organic resin; and a crystalline layered material. The organic-inorganic composite film has an average film thickness of 0.10 to 2.0 µm and contains 0.5 part or more by weight of the crystalline layered material as a solid with respect to 100 parts by weight of a solid of the organic resin. The crystalline layered material preferably is, for example, a layered double hydroxide represented by [M 2+ 1-X M 3+ X (OH) 2 ][A n- ] x/n •zH 2 O, where: M 2+ is one or more of Mg 2+ , Ca 2+ , Fe 2+ , Ni 2+ , and Zn 2+ ; M 3+ is one or more of Al 3+ , Fe 3+ , and Cr 3+ ; and A n- is one or more of OH - , CO 3 2- , Cl - , and (SO 4 ) 2- .
Abstract:
The invention relates to a method for producing a panel, in particular a furniture or flooring panel, in which a decorative finish, preferably a decorative wood finish, is applied to at least one surface of a plate-shaped substrate (2), and in which the substrate (2) or the decorative finish is provided with a flat, three-dimensional structure (8). The method is essentially characterised in that, in order to produce the structure (8), liquid and/or powdery coating material is applied in one or more layers to the substrate or to the decorative finish, regions of the applied coating material are solidified by means of at least one digitally controllable device (7), and the device (7) is controlled using structure data present in digital form.
Abstract:
A roll coater can be modified by the addition of one or more needle tubes that supply coating fluid to the roll coater in discrete locations across the face of the coating roll. The needle tubes supply a localized band of coating material onto the coating roll superimposed over the uniform coating layer already present on the surface of the coating roll from an upstream coating pond creating a stripe pattern over the uniform coating layer. By varying the relative speeds of the coating rolls in the coater, the width of the stripe can also be adjusted.
Abstract:
A method and apparatus for zone controlling the temperature of a rotating roll. The apparatus includes a roll (30) having a surface (32) at a first temperature and a belt (70) disposed adjacent at least a portion of the surface (32) of the roll (30). The belt (70) contacts the roll surface (32) in a contact region (C) and has a second temperature that is different from the first temperature of the roll (30) such that the belt (70) affects a temperature change in at least a portion of the surface (32) of the roll (30) in the contact region (C) as the roll (30) is rotated.
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Beschichten eines medizinischen Implantats, wobei die Vorrichtung einen Behälter umfasst, der eine Flüssigkeit enthält, die zumindest eine pharmazeutisch aktive Substanz umfasst, wobei die Vorrichtung einen elastischen Kopf zum Auftragen der Flüssigkeit auf eine zu beschichtende Oberfläche aufweist, der über zumindest einen Kanal mit dem Inneren des Behälters verbunden ist. Die Erfindung betrifft auch ein Verfahren zum Beschichten eines medizinischen Implantats mit einer derartigen Vorrichtung, wobei ein medizinisches Implantat bereitgestellt wird und der elastische Kopf der Vorrichtung mit der zu beschichtenden Oberfläche des medizinischen Implantats kontaktiert wird, so dass die Flüssigkeit als Film von dem elastischen Kopf auf die Oberfläche des medizinischen Implantats übertragen wird.
