Problems solved by technology

[0002] In the laboratory, glass sheets made by melting samples in high-temperature furnaces are often used. At present, when making such glass sheets, they are made by melting samples in high-temperature furnaces. When making glass sheets, the process is complicated. It is necessary to pour the molten red glass liquid on the iron plate at high temperature to form it, and then place it together with the iron plate in another high-temperature furnace for annealing. Take the glass off the iron plate
If the surface of the iron plate is smooth, the glass sheet made is basically smooth. If there is rust on the surface of the iron plate, the surface of the formed glass sheet is rough and uneven, and the rust is obvious, which seriously affects the glass transmittance.
Moreover, it is extremely unsafe to operate at high temperature (about 1400°C), and the glass is easy to burst
If the crucible with glass batch material is placed in a high-temperature furnace at 1400°C for four hours at room temperature and then taken out at room temperature, the glass will stick to the crucible wall and a complete glass sheet cannot be formed.
It is very difficult to detect the optical properties of the glass sheet produced by the above method or directly use the instrument to test the composition of the fusing glass.

Abstract

The invention discloses an application of a depilatory in glass manufacturing and a method for manufacturing glass by a depilatory; a lithium bromide solution is added into a mixed batch for glass manufacturing. The method for manufacturing glass comprises the following steps: putting a mixed glass batch in a high temperature-resistant vessel, dropwisely adding a lithium bromide solution on the surface of the batch; heating the glass batch from room temperature to 1400 DEG C within 1.5 hours, performing heat preservation for 1-5 hours, cooling to room temperature, taking out the molten glass and a crucible, pouring out the glass from the crucible to obtain a finished product. In the invention, the depilatory is applied to glass manufacturing, which is a cross-domain application, and unexpected effect is achieved. By using the depilatory, the operation method for glass manufacturing is simple, practical, safe and reliable, and the manufactured glass flake is convenient for testing.
