Home decoration will be used for plates, then how to buy plates, how to identify when purchasing plates, the following give you a few strokes: Plate purchase: 1. Look at the surface of the board for obvious flaws The surface of the decorative sheet should be smooth, free of burrs and slicing knife marks, no glue penetration phenomenon and board surface contamination phenomenon (such as local blackening and yellowing), try to choose the surface of the board without cracks, cracks, no knots, clips, The natural warpage of the entire board should be as small as possible for the resin capsules and the gum lanes, so as to avoid the phenomenon of sand penetration revealed by the base material due to improper operation of the sanding process. 2. Recognize the difference between veneer veneer and natural wood veneer veneer The former plate texture is basically a straight texture, and the texture pattern is regular; the latter plate is a natural wooden pattern, and the natural variability of the texture pattern is relatively large and irregular. 3. Panel appearance inspection The appearance of decorative panels should have a good aesthetic sense. The materials should be fine and uniform, with clear color and beautiful wood grain. The texture of the panel boards and parquet should be arranged according to certain rules. The wood color is similar, and the seams are almost parallel to the edges of the panels. 4. Sheet glue layer structure is stable, no open glue phenomenon It should be noted that bulging and delamination cannot occur between the veneer surface and the substrate, and between the internal layers of the substrate. 5. To choose low formaldehyde emission plates Do not choose stimulating decorative plates. Because the greater the odor of the plate, the higher the release of formaldehyde, the greater the pollution, the greater the danger. Sheet metal decoration decoration home decoration
Windows are desiged for use in optical systems to separate two enviroments while passing a particular spectral range between them.Applications include laser set-ups (e.g.at Brewster's angle),emitter,detector protection devices, such as in sepctrophotometers and imaging systems.
