preparation example Construction

[0049] The preparation method of the above-mentioned incompletely fused glass group comprises the following steps,

[0050] S1. Clean the glass surface first;

[0051] S2. Contacting the glass surfaces;

[0052] S3. Apply force to the glass group to make the contact part form a van der Waals force fit;

[0053] S4. Baking and heating the glass group, the heating temperature is 240-600°C, and the time is 0.5-48h;

[0054] S5. The state of the glass group in which the fusion fault can be seen under the microscope is the incompletely fused glass group.

[0055] Among them, the function of S1 is to remove impurities, so that the surface is free from dirt and micro particles, such as dust;

[0056] The function of S2-S3 is to form van der Waals bonding between the glasses.

[0057] The function of S4 is to make the fusion force of the glass greater than the breaking force of the glass, but the glass does not reach a completely molten state.

[0058] Still taking two pieces of ...

Embodiment 1

[0069] Corning Glass vs. Corning Glass

[0070] First clean the two glass surfaces; then contact the glass surfaces; then apply force to the glass group to form a van der Waals force bond between the contact parts; then bake the glass group at a temperature of 550°C for 1 hour and 30 minutes. Finally, under a high-power microscope, such as 100 times magnification, the glass group state of the fusion fault can be seen, which is the incompletely fused glass group.

Embodiment 2

[0072] Schott glass and Schott glass:

[0073] First clean the two glass surfaces; then contact the glass surfaces; then apply force to the glass group to form a van der Waals force bond on the contact part; then bake the glass group at a temperature of 530°C for 1 hour and 50 minutes. Finally, under a high-power microscope, such as 100 times magnification, the glass group state of the fusion fault can be seen, which is the incompletely fused glass group.

Abstract

The invention provides an incompletely-fused glass group and a making method thereof. The incompletely-fused glass group comprises at least two pieces of glass, wherein the surface smoothness of the glass is less than 10 nanometers; the at least two pieces of glass are jointed together; a fused fracture zone is formed between every two pieces of glass. The making method comprises the following steps: cleaning the surfaces of the two pieces of glass; making the surfaces of the two pieces of the glass come into contact with each other; applying force to the glass group to make contact parts form Van der Waals force joint; heating the glass group in a backing way at the temperature of 240-600 DEG C for 0.5-48 hours; watching the glass group state of the fused fracture zone, namely, the incompletely-fused glass group, under a microscope. In the incompletely-fused glass group, no jointing medium is used, so that the diversity of glass can be met, and the machining quality of the glass is ensured.

Description

technical field [0001] The invention relates to the field of glass products and their processing, in particular to an incompletely fused glass group and a preparation method thereof. Background technique [0002] With the rapid development of the glass industry, people have higher and higher requirements for the shape of glass. The early technical production process can only provide flat glass screens with a single shape, which cannot meet the needs of modern people for glass products with exquisite shapes. [0003] The existing glass processing includes cold processing and hot processing. Among them, cold processing is to directly CNC (Computernumerical control, computer numerical control) a piece of glass to process curved curved glass. In order to process the convex and concave surfaces of the bridge deck glass, the surface part is moved back and forth with a flat knife for many times, and the knife is moved back and forth in this way, so that the processing path covers ...
