摘要:
A liquid toner having a mineral oil vehicle, a blend of Surlyn ionomeric resin and Nucrel resin, pigment and, as charge director, lecithin, N-methyl-2-pyrrolidone and calcium Petronate. The charge director optimizes speed of recovery of charge properties during continual use. The mineral oil does not vaporize well and is readily condensed, thus permitting use as a confined toner.
摘要:
Cleaning roller (7) contacts intermediate transfer roller (4), each rotating at the same surface speed to avoid rubbing. The cleaning roller has an electric potential sufficient to remove toner from the transfer roller to clean it. Silicone oil is applied by a roller 29, which is wetted by oil from a oil impregnated wiper (31). The oil facilitates cleaning and reduces wear of the intermediate transfer roller, which is typically soft to facilitate transfer.

In imaging apparatus (1) a contact heater (9) applies heat and electrical bias to a toner image on an intermediate accumulator (5). The bias is of polarity to repel the toner. The toner image is coalesced such that additional heating may be reduced or eliminated at the transfer to paper (7) by pressure roller (11).
摘要:
A glass container and related methods of manufacturing a glass container. A solution having a composition including a silane, a solvent, a catalyst, and water, is applied to an exterior glass surface of the glass container, at an application temperature between 5 and 40 degrees Celsius, such that the solution at least partially fills the surface imperfections to provide a room-temperature-curable cold-end coating on the glass container. Then, the applied solution is allowed to cure on the exterior glass surface of the glass container, at a curing temperature between 5 and 40 degrees Celsius.
摘要:
Certain example embodiments relate to articles supporting photocatalytic layers that also include UV-reflecting underlayers, and/or methods of making the same. In certain example embodiments, the inclusion of a UV-reflecting underlayer surprisingly and unexpectedly results in the reduction of dosing time to enable quick activation of the photocatalytic coating. For example, dosing time may be reduced from a few hours to a few minutes or even seconds in certain example embodiments. The UV-reflecting underlayer may be a single-layer coating or a multi-layer stack.
摘要:
Methods of making hydrophilic coatings having anti-fog properties, and hydrophilic articles are provided. In certain example instances, a substrate supports a surfactant and polyethylenimine. The method includes forming a polyethylenimine-solvent mixture; applying a surfactant to a surface of the substrate; and applying the polyethylenimine-solvent mixture to the dried surfactant on the surface of the substrate. After drying or curing, the resulting coating may be hydrophilic thereby allowing water or the like to easily shed therefrom (e.g., providing anti-fog properties).
摘要:
Methods for forming porous anatase titanium dioxide coatings are disclosed. Sol-gel compositions are prepared having at least one porosity agent, are applied to a substrate, and at least one porosity agent is removed. Porous anatase titanium dioxide coatings having at least one of improved antimicrobial properties, self-cleaning properties, hydrophilicity, and/or temperability are also disclosed. Substrates comprising such coatings are also disclosed.
摘要:
A diffuser is provided in an illumination system, where the diffuser is capable of blocking significant amounts of infrared (IR) and/or ultraviolet (UV) radiation. In certain example embodiments of this invention, the diffuser includes a glass substrate which supports an IR/UV coating(s) that blocks significant amounts of IR and/or UV radiation thereby reducing the amount of IR and/or UV radiation which can makes its way through the diffuser. In certain example embodiments, the coating may include particulate in a frit matrix so that the coating may both diffuse visible light and perform IR and/or UV blocking.
摘要:
A method of making an anti-reflection coating using a sol-gel process, for use in a photovoltaic device or the like. The method may include the following steps in certain example embodiments: forming a polymeric component of silica by mixing silane(s) with one or more of a first solvent, a catalyst, and water; forming a silica sol gel by mixing the polymeric component with a colloidal silica, and optionally a second solvent; forming a metal oxide sol by mixing silane(s) with a metal oxide, a second catalyst, and a third solvent; forming a combined sol by mixing the metal oxide sol with the silica sol; casting the mixture by spin coating or the like to form a silica and metal oxide containing layer on a substrate; and curing and/or heat treating the layer. This layer may make up all or only part of an anti-reflection coating which may be used in a photovoltaic device or the like.
摘要:
The present application is directed to methods of controlling the transfer voltage in a transfer nip formed between the photoconductive member and the transfer member. The methods offset the effects of large transfer current spikes caused when a media sheet enters and exits the transfer nip. The control may include either ramping up or ramping down the transfer voltage. The ramped transfer voltage may include a series of alternating positive and negative steps that generally trend to ramp up or down. The size of the steps may further be adjusted to provide a smooth transition.
