تعريف sand-blasting في الإنجليزية الإنجليزية القاموس.
Compressed air forces an abrasive material (resembling sand) through a nozzle on to the surface of the glass This process removes the surface of the glass, which gives the sandblasted area a frosted look Sash A wood perimeter around the glass which allows some independent movement from the frame (not direct set) Sash has two types of components: Stiles-the vertical perimeter pieces Rails-the horizontal perimeter pieces Sash Opening The space described by the interior of a window frame It is bounded by the interior surface of the frames Jamb liners or hardware adapters must be disregarded (Primary use of this dimension is for the Replacement Double Hung System)
or SAND ETCHING: technique in which sand or grit is forced through high pressure to etch a pattern
A means of producing a matte or frosted finish on gold and other metals This is accomplished by holding the work against a stream of sharp sand driven by a jet of compressed air
The process of surface cleaning and roughening that provides a mechanical "tooth" to aid coating adhesion Media include aluminum oxide, even crushed walnut shells The medium must be chosen to match the substrate and the foreign material on the substrate to be removed
Procedure for cleaning of metal surfaces, for which fine silica sand is blasted through a nozzle onto the surface by means of compressed air to remove scale as well as other coverings
A method for decorating glass or wood A rubberized stencil of the artwork is either hand- or computer-cut and applied to the substrate, which is then sprayed with a pressurized stream of sand or synthetic particles to texture the areas unprotected by the stencil Once the desired depth has been achieved on the item being blasted, the stencil is removed, and if on wood, the surfaces may be painted
Use of pressured air to propel sand or aluminum oxide grit in a controlled way so that glass may be sculpted away Requires some type of breathing protection whether a NIOSH rated mask, a closed rebreathing system or a controlled atmosphere like a sandblasting box Small inexpensive systems using "canned" air can be used for small projects
