Quality inspection method of high temperature glass
Unlike toughened glass, high temperature glass itself has no condensation capacity and no flying phenomenon even under external impact. In daily life, according to the national testing standards, how to identify the quality of high-temperature glass materials should be analyzed from the following two aspects:
1. As the glass itself has a transparent and beautiful effect, we should check the surface of the glass during the test. By observing and rubbing, we should select the surface without bubbles, inclusions, scratches and fog spots. Because if the glass has the above defects, it will reduce the transparency, mechanical strength and heat resistance of the glass itself.
2. In addition to the visual inspection of the glass surface, it is also necessary to check the processing accuracy of the glass, check whether the size meets the customer's requirements, and there should be no ripple, bubble and layered stripe produced by the heterogeneity of the glass body. The inner concave and outer convex of large surface of glass brick shall be less than 1mm, and the outer convex shall be less than 2mm. The weight shall meet the quality standard, without surface warpage, notch, burr and other quality defects, and the angle shall be square.
According to different application fields, with the influence of industry and daily life, high temperature glass is widely used. It has special applications in food machinery, chemical fiber, optical military industry, steel and cement, scientific manufacturing, etc. High temperature glass has good heat resistance and heat insulation effect.
