At present, the glass market has grown increasingly popular, and the detection of glass quality can also be important when purchasing magnifying glaas. For the inspection involving glass sheets, the appearance quality is mainly to check the flatness and observe the high quality defects such as bubbles, inclusions, scores, lines and fog locations. If there is a great defective glass, deformation may occur during use, which reduces the transparency with the glass, mechanical strength and thermal stability in the glass, and is not well suited for engineering use. Since the glass is usually a transparent object, the appearance can be detected in the time selection, and the quality can be basically identified.
Inspecting goblet processed products, in addition on the requirements of flat tumbler, should also check the processing quality, check whether the typical size, processing accuracy and pattern definition meet what's needed, and the side just isn't allowed to be malfunctioning.
The appearance quality on the hollow glass brick shouldn't be cracked, and there must be no opaque unmelted material inside the glass blank, and the welding and bonding between both glass bodies cannot often be poor. Visual inspection on the brick body should be without any corrugations, bubbles and lamellar streaks resulting from inhomogeneities within the glass blank. The outer surface with the large surface of the glass brick needs to be less than 1 mm, the convexity needs to be less than 2 mm, the weight should meet the high quality standard, no surface warpage, level, burr and other top quality defects, the angle ought to be square. The above is a general method for identifying the grade of glass. Special glass must be tested with special tools.
