Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and in particular to green energy-saving glass and a production method thereof. Background Art

[0002] In the glass production process, energy consumption primarily occurs in key steps such as melting, forming, and annealing. The melting process is the most energy-intensive. Here, heating the raw materials to high temperatures to melt them into liquid glass consumes significant amounts of heat energy. The glass bottle forming process also involves some energy consumption, although this is lower compared to the melting stage. The slow cooling process during annealing also requires furnace temperature control, which similarly requires continuous energy input to maintain a stable temperature.

DETAILED DESCRIPTION

[0041] The present invention will be further described below with reference to the following embodiments. The following description is merely a preferred embodiment of the present invention and does not limit the present invention in any other form. Any person skilled in the art may utilize the above disclosed technical content to make equivalent embodiments with equivalent variations. Any simple modification or equivalent variation of the following embodiments made in accordance with the technical essence of the present invention without departing from the content of the present invention shall fall within the scope of protection of the present invention.

[0042] Example 1: Production process of green energy-saving glass

[0043] The raw materials for ordinary glass primarily include silicon dioxide (SiO2), aluminum oxide (Al2O3), calcium oxide (CaO), magnesium oxide (MgO), sodium oxide (Na2O), and potassium oxide (K2O). Silicon dioxide is the primary component of glass, contributing to its transparency, mechanical strength, chemical stability, and thermal stability. However, its high melting point and high melt viscosity make melting difficult and increase heat consumption, necessitating the addition of other ingredients. These other ingredients enhance chemical stability, mechanical strength, and thermal stability, and their content must be controlled within a certain range to ensure the glass's excellent properties.

[0044] In recent years, the use of recycled glass has reduced the dependence of glass production on raw materials and reduced the energy requirements of the melting process. This embodiment, by debugging a variety of new glass raw materials, aims to achieve a green and energy-saving glass production process by lowering the melting temperature of the glass mixture.

[0045] The following table is the raw material composition of traditional glass:

[0046] Composition of raw materials Number of copies Silicon dioxide 100 Alumina 5 calcium oxide 5 magnesium oxide 3 Sodium oxide 3 potassium oxide 2

[0047] In this embodiment, new raw materials are added to the above raw materials. The new raw materials are shown in the following table:

[0048] New raw materials Number of copies <![CDATA[Titanium dioxide TiO2]]> 2、5、10 Zinc oxide ZnO 2、5、10 <![CDATA[Calcium fluoride CaF2]]> 2、5、10 <![CDATA[Magnesium fluoride MgF2]]> 2、5、10 <![CDATA[Aluminum telluride Al2Te3]]> 2、5、10 <![CDATA[Potassium telluride K2Te]]> 2、5、10 Calcium telluride (CaTe) 2、5、10

[0049] Add a new raw material to each of the above raw materials for traditional glass, and prepare the glass according to the following steps. Record the melting temperature after adding the new raw material:

[0050] The glass materials are crushed and mixed; the mixture is put into a furnace for heating, and the mixture is heated and stirred evenly to form glass liquid. The preset temperature is 1000℃. If the mixture cannot be melted into glass liquid, it is further heated by 50℃, and so on; the glass liquid is injected into the preheated mold; the mold is placed in a constant temperature oven and cooled to room temperature.

[0051] The melting temperatures of different glasses are as follows (parts refer to the parts of new raw materials):

[0052]

[0053] 30 parts of recycled glass were added to the raw materials of conventional glass (the second glass preparation method), which is recorded as conventional glass 2 in this embodiment. Then, the new raw materials were added and the glass was prepared according to the above steps. The melting temperature was recorded as follows:

[0054]

[0055]

[0056] According to the above results, adding titanium oxide (TiO2), calcium fluoride (CaF2), aluminum telluride (Al2Te3), and potassium telluride (K2Te) to the raw materials of glass can significantly reduce the melting temperature of glass, adding zinc oxide (ZnO) and calcium telluride (CaTe) can slightly reduce the melting temperature of glass (the melting temperature of glass without recycled glass components has a greater impact), and adding magnesium fluoride (MgF2) cannot reduce the melting temperature of glass.

[0057] Although the specific embodiments of the present invention have been described in detail, those skilled in the art will understand that various modifications and changes can be made to the details based on all the teachings published, and these changes are all within the scope of protection of the present invention. The entire invention is given by the appended claims and any equivalents thereof.
