Preparation method of tempered glass gas stove panel

Abstract

The invention discloses a method for preparing a tempered glass gas stove panel. The ordinary silicate glass containing alkali metal ions is immersed in an alkali salt solution in a molten state and kept for a certain period of time, and then taken out. The alkali in the alkali metal salt The ionic radius is greater than the alkali ion radius in the silicate glass; cool down the treated glass taken out, wash off the alkali salt on it, and dry it to obtain the treated tempered glass. Through the above method, the method for preparing tempered glass of the present invention is simple to operate, the entire operation process is safe and reliable, and there is no operational risk. The obtained tempered glass is broken into small particles, which is less harmful to the human body. The tempered glass has impact resistance It has the advantages of non-resistance, bending resistance, good thermal stability, and high strength. It has a wide range of applications and is deeply loved by consumers.

Description

technical field

[0001] The invention belongs to the technical field of casting, and in particular relates to a preparation method of a toughened glass gas stove panel. Background technique

[0002] One of the disadvantages of ordinary glass is that it is easy to break, and people who are broken will be injured if they accidentally touch it, causing bleeding and causing certain harm to people's physical and mental safety. Tempered glass is a type of safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, 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 wind resistance of the glass itself. Sex, cold and heat, impact, etc. However, the preparation process of the physical method will be carried out at high temperature, which is prone to safe...

Examples

Embodiment

[0010] A method for preparing a tempered glass gas stove panel of the present embodiment comprises the following steps:

[0011] 1) Immerse ordinary silicate glass containing alkali metal ions in the molten alkali salt solution for 4 hours and then take it out, wherein the alkali ion radius in the alkali metal salt is larger than that in the silicate glass;

[0012] 2) The temperature of the treated glass taken out is lowered, the drying temperature is 350°C, the alkali salt on it is washed off, and dried to obtain the treated tempered glass.
