The method is: in a glue seam divided into two gluing process. First, according to the conventional glue method for joint treatment. When the first glue is solidified, the first glue is played on the top of another, and the shape is trimmed as a convex arc section, so that it is wider than the first glue, so that the two sides of the second glue are bonded on the glass surface on both sides of the joint.
This form of glue expands the bonding surface and sealing width, and is beneficial to alleviate local stress (especially at the intersection), while covering the first sealant in the construction may appear defects. It is helpful to eliminate the hidden danger of leakage completely.
