摘要:
A method of forming a polymer film includes dispensing a substrate and coating the substrate with a composition that is curable using actinic radiation. In an example, the method further includes exposing the composition to actinic radiation in presence of an atmosphere including 1 vol % to 37 vol % oxygen, whereby the surface of the composition forms an undulating morphology. In another example, the method further includes applying an oxygen-containing overlay over the composition, exposing the composition to actinic radiation through the oxygen-containing overlay, and removing the oxygen-containing overlay, whereby the surface of the composition forms an undulating morphology.

An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group define a first non-shadowing distribution relative to each other.
摘要:
A surface-modified abrasive grain includes an abrasive grain as a substrate, and a film on the abrasive grain that includes a relatively hydrophilic silane component and a relatively hydrophobic silane component. The film can be a single film layer or multiple film layers, wherein a film layer most proximal to the abrasive grain has a predominately hydrophilic silane component, and a film layer more distal to the abrasive grain includes predominately a relatively hydrophobic silane component. Coated abrasive products and bonded abrasive products include the surface-modified abrasive grains.
摘要:
A composition capable of coating a substrate and curing to provide a hydrophobic film inhibiting corrosion, the composition comprising: (a) a bis-silane comprising between about 0.5 weight percent to about 50 weight percent of the composition; and (b) a water soluble or dispersible polymer comprising between 10 weight percent to about 80 weight percent of the composition. A further exemplary superprimer in accordance with the instant invention includes a composition capable of coating a substrate and curing to provide a hydrophobic film inhibiting corrosion, the composition comprising: (a) a mixture of silanes; (b) a dispersible or soluble resin; and (c) an aqueous or non-aqueous solvent. Moreover, the invention includes the aforementioned superprimer composition, wherein the mixture of silanes includes at least one of a bis-sulfur silane, a bis-benzene silane, a bis-alkane silane, a bis-alkene silane, and a bis-amino silane.
摘要:
A system and method for fault detection and recovery in a medical imaging system are provided. The method includes monitoring operations of a plurality of subsystems of the medical imaging system and determining if an error has occurred in a subsystem based on the monitoring. The method further includes identifying at least one component within the subsystem having the determined error and automatically restoring the at least one component in the identified subsystem having the determined error.
摘要:
An engineered coated abrasive product having a backing, a frontfill coat, a make coat, and/or a size coat, wherein at least one of the coats includes fibrillated fibers. The coated abrasive product is capable of improved inter-layer adhesion, retention of abrasive grains, and/or maintenance of abrasive grains in a more desirable orientation for grinding.
摘要:
A coated abrasive article includes a backing having a surface, a plurality of abrasive regions overlying the surface in each of the first and second portions, and at least one macro-channel. The surface of the backing has a shape defined by an outer contour. A bisecting axis divides the shape into first and second portions. Each abrasive region includes a binder and a plurality of abrasive grains in contact with the binder. The abrasive grains have an average grain size of not greater than about 200 microns. The at least one macro-channel defines a passageway extending between a pair of adjacent abrasive regions and terminating at openings at the outer contour within each of the first and second portions. The macro-channel has an average channel width of between about 0.1 millimeters to about 5 millimeters and is substantially free of the binder and the abrasive grains.
