1. Inspection of glass sheet

Appearance quality is mainly to check smoothness, observe whether there are bubbles, inclusions, scratches, lines and fog spots and other quality defects, there are such shortcomings of glass, in use will be deformed, reduce the transparency of glass, mechanical strength and thermal stability of glass, engineering should not be selected. Because the glass is a transparent object, in the selection of visual inspection, the basic quality can be identified. The inspection of glass processing products, in addition to the inspection of flat glass requirements, should also test its processing quality, inspection specifications and sizes are standard, processing accuracy and design clarity meet the requirements, while the side is not allowed to have incomplete. The exterior quality of hollow glass brick does not allow crack, in vitreous body do not allow opaque not melt content, do not allow the fusion between two vitreous body and glue to receive undesirable. Visually, the brick body should be free of corrugations, bubbles and layered stripes caused by uneven glass body.
