摘要:
The invention concerns a method for manufacturing a frosted glass sheet comprising (i) a step of fluidising particles having an average size of between 5 and 500 microns in a first fluid and a second fluid, using a fluidised bed technique, the first fluid being a gas and the second fluid being a liquid, so as to generate a flow of the fluidised particles having a speed of between 5 and 20 metres per second; and (ii) a step of treating a surface of a sheet of glass by exposing said surface to said flow of fluidised particles. Such a method can be used for frosting the whole of the treated surface in a uniform and homogeneous manner and produces a texture/appearance close to those obtained by chemical frosting, while avoiding the use of fluorinated compounds, which are detrimental to the environment and health.

Surfaces must be partially roughened before being painted and coated. This usually is done by blasting the surface with sand or glass particles. In this type of pre-treatment sand or other blasting medium accumulates and can contaminate the part to be cleaned. In particular in the food, automotive, and medical sectors, entrainment of blasting medium is undesirable. According to the invention, during the treatment of surfaces a blasting material is used which consists of solid carbon dioxide obtained by freezing of liquid carbon dioxide. In this way a residue-free sublimating blasting medium is attained. By comparison with dry ice particles which have been produced by compression of carbon dioxide snow, the blasting medium according to the invention has a significantly higher hardness and ensures a substantially greater mechanical abrasion of the treated surface.

Provided is a solar cell module which has an anti-glare property and is capable of exhibiting a high antifouling property. A surface of a plate body made of glass in a solar cell module is roughened, and further, an antireflection film is laminated thereon. A change point at which the slope of the contour line of the surface is changed steeply is made to exist on a cross-section cutting through the plate body in the thickness direction. Where with the change point as a boundary, a straight line obtained by pseudo-leveling of the contour line existing within 0.7 micrometer on one side is a one-side pseudo-straight line and a straight line obtained by pseudo-leveling of the contour line existing within 0.7 micrometer on another side is an other-side pseudo-straight line, a steep slope portion in which an angle formed by the one-side pseudo-straight line and the other-side pseudo-straight line is 135 degrees or less, and a large crack having an opening width of 0.2 micrometer or more are distributed with the total number thereof being less than 5 per each 58-micrometer compartment range.

A method of processing a surface of a metallic implant, such as a dental implant, to provide a desirable surface roughness, comprising subjecting the metallic implant to blasting with particles of one or more titanium oxides, including at least one non-stoichiometric titanium oxide, said particles having a compact morphology and a particle size in the range of from 1 to 300 μm. The resulting implant surface showed unexpectedly high retention strength after implantation in bone.

The present invention provides a method and a device for treating a surface (4') of a fiber composite material (1) comprising fibers (3) of a specific hardness (HF), wherein the surface (4') of the fiber composite material (1) is abrasively removed using an abrasion means (5) having a hardness (H A ), said hardness (H A ) being less than the hardness (H F ) of the fibers (3) contained in the fiber composite material (1) and greater than the hardness (H κ ) of a plastic (2) in which the fibers (3) of the fiber composite material (1) are embedded.
摘要:
Disclosed herein are methods of modifying a nitinol surface by using abrasive blasting techniques. The surface modification can be performed by abrasively blasting the surface and delivering at least one dopant from one or more fluid jets to cause the at least one dopant to impregnate and/or coat the nitinol surface. The nitinol surface can form a portion or all of a medical device, such as an implantable medical device, e.g., a stent.
