In the selection of tempered glass, the general need to pay attention to the following:
  1. See debris: can look at the business under the cutting of the corners of the waste is broken into a small obtuse angle particles, so to determine whether qualified. When the qualified tempered glass is broken, the number of pieces in the 50 mm × 50 mm area must exceed 40, allowing a small amount of long pieces of debris, the glass slag can not be in the form of a blade, and the direction of the long debris should be substantially parallel to the edge of the glass , If not parallel, the angle can not exceed 45 degrees. If there is a non-compliance, that is, substandard products.
  2. Look at the stress spot: in some special natural light (or polarized light) conditions, observe the reflected glass of the glass, you can see the glass surface there are light and dark stripes, this inconsistent brightness is called the stress spot. At present the most advanced technology in the world can not completely eliminate the stress spot, but can be reduced. Stress spot light, the better the quality.
  3. See flatness: the flatness of tempered glass slightly worse than the annealed glass, should be selected by comparing the smoothness of the good.
  4. To see whether the homogeneous treatment: blew is the inherent characteristics of tempered glass, it is difficult to avoid. But if through homogeneous treatment, you can eliminate more than 90% of the blew hidden. Select the product must look at the product, to find out whether the homogeneous treatment.
  5. Look at the glass there is no 3C certification mark. Steel equipment factory are qualified, will be printed on the glass printed on the 3C logo. Safety glass in accordance with the provisions must be 3C logo.
