Problems solved by technology

But the uniformity of cooling is difficult to control, so it is rarely used at present
The principle of liquid tempered glass is mentioned in "Glass Technology" edited by Northwest Institute of Light Industry, but no specific process and application examples are given.

Embodiment 1

[0007] Example 1: First, cut flat glass with a thickness of 5 mm and no defects into glass blocks of 150 mm × 150 mm, after edging, clean, wipe and put into a frame made of stainless steel; then place the frame with glass in a muffle In the furnace, raise the temperature from room temperature to 600°C at a rate of 5°C / min, and keep it warm for 30 minutes; then quickly immerse the frame with flat glass in 150°C methyl silicone oil (to make the temperature of the methyl silicone oil uniform first Put the methyl silicone oil in the oven to heat, and stir it with a magnetic stirrer), and let it stand for 10 minutes; finally, take out the flat glass and the frame and put it in an oven at 200°C for 30 minutes, then cool it naturally with the oven to room temperature; take it out The flat glass is cleaned with carbon tetrachloride first, then with water, and then dried to obtain tempered glass. The impact resistance of the sample was measured by the GB9963-88 impact test. The weight ...

Embodiment 2

[0008] Embodiment 2: First, cut flat glass with a thickness of 10 mm and no defects into glass blocks of 150 mm × 150 mm, clean it after edging, and put it into a frame made of stainless steel after wiping it clean; then place the frame with flat glass on a horse In a Furnace, raise the temperature from room temperature to 550°C at a rate of 3°C / min, and keep it warm for 60 minutes; then quickly immerse the frame with flat glass in methyl silicone oil at 200°C, and let it stand for 5 minutes; finally put the flat glass The glass and frame are taken out and placed in an oven at 200°C for 30 minutes, and then cooled to room temperature naturally with the furnace; after taking out the flat glass, first clean it with carbon tetrachloride, then clean it with water, and dry it to obtain tempered glass. The impact resistance of the sample was measured by the GB9963-88 impact resistance test. The weight of the steel ball was 618 grams. The impact resistance of the sample was measured t...

Embodiment 3

[0009] Embodiment 3: First, clean the wide-mouth glass bottle without defects, wipe it clean and put it into a frame made of stainless steel; then place the frame with the glass bottle in a muffle furnace at a heating rate of 20° C. / min Rise from room temperature to 580°C and keep warm for 50 minutes; then quickly immerse the frame containing the glass bottle in 180°C methyl silicone oil and let it stand for 8 minutes; finally take out the frame containing the glass bottle and put it in an oven at 200°C After keeping warm for 30 minutes, cool down to room temperature naturally with the furnace; take out the glass bottle, wash it with carbon tetrachloride first, then wash it with water, and dry it to get tempered glass. The impact resistance of the bottle body was measured by the GB9963-88 impact resistance test. The weight of the steel ball was 618 grams. The impact resistance of the sample was measured to be 0.8m, and it was not broken after three impacts.

Abstract

The invention provides a method for manufacturing toughened glass. Firstly, a glass product to be toughened are put in a stainless steel frame; the frame accommodating the glass product is placed in a muffle furnace and subjected to high-temperature treatment and then is quickly immersed in methyl silicone oil; the glass productand the frame are taken out and put in an oven and naturally cooled down to the room temperature along with the oven; the glass product is taken out, subjected to washing with carbon tetrachloride and washing with fresh water, and mopped up to obtain the toughened glass. In the invention, the methyl silicone oil is used as a cooling fluid, no additive is required to be added, and the manufacture process is simple; the toughened glass produced by the method of the invention has the advantages of high strength, low cost and high rate of finished products, etc.; moreover, the equipment is simple and the investment is low; the invention can be applied to the toughening of plate glass as well as the toughening of special products, such as glass lamp shades and wide mouth glass bottles, etc. The toughened glass made by the method of the invention has advantages of uniform stress distribution, high resistance to impact and good toughening effect.

Description

technical field [0001] The invention relates to a method for preparing glass, in particular to a method for preparing tempered glass. Background technique [0002] Glass has a series of excellent physical and chemical properties. It has high compressive strength, high hardness, transparency, good stability, and is not easy to deform. It is an inorganic non-metallic material with a wide range of uses. However, glass is a typical brittle material with low tensile strength, surface and internal defects, and crack propagation is very easy to occur under the action of external force and environmental medium, which is greatly restricted in application. With the development of science and technology, the scope of application of glass is more and more extensive, and the requirements for the strength of glass are also getting higher and higher. However, due to the influence of microcracks on the surface, the actual strength of glass is only a few hundredth of its theoretical strengt...
