Toughened glass and manufacturing method of toughened glass

Abstract

The invention relates to the technical field of tempered glass, in particular to tempered glass and a manufacturing method of the tempered glass. The tempered glass comprises an I-type tempered glasslayer and an II-type tempered glass layer, and is manufactured through a cutting forming method, a layered tempering method, a homogenizing treatment method and a hot-dipping aging method. A change difference of the temperature of environments where the surfaces of the two sides of the tempered glass are located is transmitted to the interior of the tempered glass through a hardened layer on the surface, and interference is generated at a stress junction, so gradually-accumulated stress difference quantitatively changes to generate qualitative change damage in the internal structure of the tempered glass, and self-bursting of the tempered glass is caused. According to the invention, the I-type tempered glass layer and the II-type tempered glass layer are arranged in the tempered glass, andthe I-type tempered glass layer and the II-type tempered glass layer are of different metallographic structures in the thermal deformation process of the tempered glass, so resonance effect in deformation between the I-type tempered glass layer and the II-type tempered glass layer is avoided, and then the spontaneous explosion phenomenon of the tempered glass is prevented; and therefore, the application effect of the toughened glass is improved.

Description

technical field [0001] The invention relates to the technical field of tempered glass, in particular to a tempered glass and a method for manufacturing the tempered glass. Background technique [0002] Tempered glass is a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the durability of the glass itself. However, the self-explosion phenomenon of tempered glass in use has become a difficult problem to be solved in the development of tempered glass. From improving the manufacturing method and installation environment of tempered glass to reducing the possibility of self-explosion, the introduction of tempered glass , see: Ding Zhilong, Cause Analysis and Preventive Measures of Curtain Wall Tempered Glass Self-explosion [J...

AI Technical Summary

Problems solved by technology

[0003] After the tempered glass is installed, the difference in ambient temperature on both sides of the surface is transmitted to the interior of the tempered glass through the hardened layer on the surface, causing interference at the stress junction, and the gradually accumulated stress difference changes in the internal structure of the tempered glass. The qualitative change and damage in the medium will cause the self-explosion phenomenon of the tempered glass and reduce the service life of the tempered glass

[0004] There are also some technical solutions about tempered glass and the manufacturing method of tempered glass in the prior art. For example, a Chinese patent with application number 031600425 discloses a double-sided tempered vacuum glass and its manufacturing method. The vacuum glass includes an upper layer and a lower layer. Tempered glass; the surface of the lower layer of tempered glass is provided with a support, the upper layer of tempered glass is placed on the support, a space is formed between the two layers of tempered glass, and the peripheral ring of the two layers of tempered glass is formed by low glass powder after thermal melting and cooling. Solidified body, two layers of tempered glass are tightly sealed to form the main body of vacuum glass; the surface of the upper layer of tempered glass is sealed; the space between the two layers of tempered glass is in a vacuum state; its manufacturing method includes cutting ordinary flat glass and drilling holes, It is tempered; any glass surface is coated with low glass powder and placed on a support; the uncoated flat glass with low glass powder is placed on the support, and sintered so that the molten low glass powder tightly seals the periphery of the two layers of glass Sealing; the drilled hole is sealed after low-temperature exhaust; this technical plan uses two tempered glass to make vacuum glass, which has good heat insulation and sound insulation effects, is not easy to break, and will not cause harm to people; Solve the problem that the difference in ambient temperature on both sides of the tempered glass will interfere with the stress junction after being transmitted to the interior of the tempered glass, which will affect the structural stability of the tempered glass
