Tempered glass and manufacturing method thereof

Abstract

The invention belongs to the technical field of tempered glass production, and particularly relates to tempered glass and a manufacturing method of the tempered glass. The tempered glass is prepared from the following raw materials in parts by weight: 25-40 parts of silicon dioxide, 10-16 parts of limestone, 10-14 parts of kaolin, 14-23 parts of mirabilite, 5-10 parts of sodium carbonate, 5-11 parts of recycled cullet, 4-7 parts of aluminum powder, 0.5-1 part of antimony trioxide and 0.2-0.3 part of ammonium nitrate. According to the invention, the clarifying device is arranged and can play a role in defoaming the interior of molten glass, so that bubbles in a glass finished product can be reduced, the breaking strength of the glass can be greatly improved, and meanwhile, the visibility of the glass is higher and the glass is more attractive; and during actual work, molten glass sprayed on the upper surface of a convex ring can flow downwards and be paved along the upper surface of the convex ring, and a vibration exciter positioned in the annular cavity can enable the surface of the convex ring to vibrate at the moment, so that tiny bubbles in the molten glass paved on the surface of the convex ring are removed through vibration, and the defoaming effect is further improved.

Description

technical field [0001] The invention belongs to the technical field of tempered glass production, in particular to a tempered glass and a method for manufacturing the tempered glass. Background technique [0002] Tempered glass is glass with compressive stress on the surface, also known as strengthened glass, which is strengthened by tempering method. Tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form stress on the glass surface. The external force of the glass first offsets the surface stress, thereby improving the bearing capacity. , enhance the glass's own pressure resistance, cold and heat resistance, impact resistance, etc. When the glass is damaged by external force, the fragments will become honeycomb-like obtuse-angle broken particles, which are not easy to cause serious harm to the human body. Tempered glass has good thermal...

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, most of the methods currently used to eliminate the bubbles in the molten glass are by stirring or adding defoamers, but these two This method is not good for removing microscopic air bubbles in molten glass. The present invention proposes a tempered glass and a method for manufacturing tempered glass.
