2364 results about "Toughened glass" patented technology

Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.

Natural rubber press plate with four edges capable of being adjusted to one plane through skewed slots

The invention relates to a press plate for glass testing, and especially relates to a natural rubber press plate with four edges capable of being adjusted to one plane through skewed slots. The press plate is composed of a clamping part and a sliding part. The improvements of the press plate are as follows: the sliding part is arranged on one end of the clamping part and is overlapped on the upper surface of the clamping part; the lower surface of the sliding part is taken as the sliding lower plane, the sliding lower plane is provided with a trapezoidal emboss, the upper surface of the clamping part is the clamping upper plane, and the clamping upper plane is provided with a trapezoidal groove. The sliding lower plane and the clamping upper plane are in the same height. The inner side of the clamping part is provided with a clamping slope, and a rubber press sheet is adhered on the clamping slope. The angle between clamping slope (15) and the clamping upper plane (16) is 51 to 53 degrees. A layer of rubber press sheet (51) is adhered on the clamping slope (15), and the thickness of the rubber press sheet (51) is 2.1 to 2.3 millimeters. When the width is adjusted to limit a tempered glass sheet (100) in the horizontal direction, and a downward force can be generated at the same time, so the tempered glass sheet (100) can be pressed against the flat plate (50) of a test platform so as to avoid the explosion of the tempered glass sheet (100) due to the uneven stress on the tempered glass sheet (100).
