| Inspection of glass panels, the appearance of quality is mainly to check flatness, observation of the bubble, inclusions, scratches, lines and fog spots and other quality defects, the existence of such defects of glass, in use will occur deformation, reduce glass transparency, mechanical strength and thermal stability of the glass, the project is not suitable for selection. Since glass is a transparent object, when selected through visual inspection, basic can identify the quality of good or bad. Inspection of glass processing products, in addition toFlat GlassThe requirements of testing, but also to test the quality of its processing, the size of the test specifications, processing precision and clarity of the pattern, and so on, while the side is not allowed to be incomplete. The appearance quality of the hollow glass brick does not allow the crack, the glass body is not allowed to have the opaque molten matter, does not allow two of vitreous fusion and the bonding between the bad. Visual bricks should not have corrugated, bubbles and the uneven quality of the glass body in the layer-like stripes. Glass bricks on the surface of the large surface concave should be less than 1 mm, external convex should be less than 2 mm, weight should meet the quality standards, no surface warping and notch, burr and other quality defects, angle to founder.  |
