摘要:
A method of manufacturing an electrowetting device including forming a cavity between first and second support plates which narrows towards a constriction. The cavity is at least partly filled with second fluid to provide a reservoir for dispensing second fluid between the first and second support plates.

The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around.

A hydrophilic member includes a base material; and a layer containing a hydrophilic material (1) and an oligomer or polymer (2), the layer is a composition gradient layer in which a composition of (1) and (2) continuously changes in a thickness direction of the layer in such a manner that a ratio of (1) becomes large, whereas a ratio of (2) becomes small, from the nearest side to the base material toward the farthest side to the base material, the hydrophilic material (1) is a hydrophilic material containing a hydrolyzable silyl group-containing hydrophilic polymer, the polymer having at least one hydrolyzable silyl group represented by the formula (a) as defined herein at a main chain end or side chain of a molecule thereof and having at least one hydrophilic group in the molecule, and the oligomer or polymer (2) is different from the hydrophilic polymer (1).
摘要:
Sprayable polyurethane compositions contain particulate filler in both polyol and isocyanate components for a total content of minimally 20 weight percent of particulate filler. The isocyanate component is stable with respect to storage, and composite structures prepared therefrom exhibit high modulus and can be used as replacements for unsaturated polyester systems.
摘要:
A simultaneous interpenetrating polymer network - geopolymer epoxy composition includes a first component comprised of a waterborne epoxy curing agent, an aluminosilicate source, and an amorphous silica, and a second component comprised of an epoxy resin and an alkaline silicate solution. The two components are mixed to produce a SIN-GE composition that cures at ambient temperatures. The SIN-GE composition may be a low- viscosity, sprayable composition, or may be a higher-viscosity composition. The compositions may be used as coatings, adhesives, mortars, casting materials, and the like.
摘要:
A system for purging a plural component coating application system includes a pressure regulator for receiving an inert gas, providing the inert gas at a pressure sufficient to maintain the atomization pressure of a coating spray pattern; a valve in fluid communication between the upstream side of the valve and the regulated side of the pressure regulator; and an operator to open and close the valve. The operator can be controlled with a logic controller. The system also includes a check valve; a mixing manifold in fluid communication with the downstream side of the first check valve; another pressure regulator for receiving an inert gas, providing the inert gas at lower pressure.
摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur Applikation einer Flüssigkeit auf ein Substrat (4), wobei die Flüssigkeit beim Austritt aus einem Behälter (2) ein poröses Material (3, 8) durchläuft, welches mit dem Substrat in Kontakt steht, und das poröse Material mit einem Markierungsmittel versehen ist, welches die Applikationsstelle (5) der Flüssigkeit auf dem Substrat markiert.
