Quality evaluation of glass materials
1. Inspection of glass plates. Appearance quality If you check the flatness, observe the presence of air bubbles, inclusions, scratches, line and fog, and other defects, the glass with such defects will deform during use, and will reduce the transparency and mechanical strength of the glass. The thermal stability of glass and glass should not be used in engineering. Since the glass is a transparent object, visual inspection can basically identify the quality.
2. Inspection of glass processed products. In addition to testing according to the requirement of plate glass (plate glass related door and window information), the processing quality should also be inspected to check whether the specification size is standard, the processing accuracy and pattern clearness meet the requirements, and at the same time, the edge is not allowed to have defects.
The appearance quality of the hollow glass bricks is not allowed to have cracks, the glass blanks are not allowed to have opaque unmelted materials, and the welding and glue bonding between the two glass bodies are not allowed. Visually, the brick body should not have lamellar stripes due to inhomogeneities in corrugations, bubbles, and glass blanks. The outer surface of the glass brick should be less than lmm in the large surface, less than 2mm in the convex, and the weight should meet the quality standards. There should be no surface warpage and defects such as notches and burrs. The angle should be squared.
