Messaggiodi ahwhglass il 8 novembre 2018, 4:56

At present, the glass market has become increasingly popular, and the detection of glass quality is usually important when purchasing glass. For the inspection regarding glass sheets, the appearance quality is principally to check the flatness and observe the standard defects such as bubbles, inclusions, scores, lines and fog spots. If there is such a defective glass, deformation will probably occur during use, which reduces the transparency on the glass, mechanical strength and thermal stability from the glass, and is not made for engineering use. Since the Laminated wire glass can be a transparent object, the appearance can be detected before selection, and the quality is often basically identified.

Inspecting glass processed products, in addition for the requirements of flat tumbler, should also check the processing quality, check whether the common size, processing accuracy and pattern definition meet the requirements, and the side is not allowed to be defective.

The appearance quality with the hollow glass brick ought not be cracked, and there need to be no opaque unmelted material while in the glass blank, and the welding and bonding between both the glass bodies cannot often be poor. Visual inspection of the brick body should be without any corrugations, bubbles and lamellar streaks resulting from inhomogeneities in the glass blank. The outer surface on the large surface of the glass brick must be less than 1 mm, the convexity should be less than 2 mm, the weight should meet the product quality standard, no surface warpage, notch, burr and other level of quality defects, the angle must be square. The above is some sort of general method for identifying the caliber of glass. Special glass must be tested with special technology.
