Glass melting temperature

The glass melting temperature depends on the type of glass. Each glass has unique characteristics.

Characteristics of alkali aluminosilicate glass differs from phosphate or brosilicate glass.

Therefore, there is a need for changes in the raw materials and their manufacturing process.

When they melt ordinary glass, it becomes viscous. Lowering the temperature causes this property to lose its crystallinity. Glass requires very high temperatures to achieve this property. Normal glass melting temperatures are above 900 ° C.

Manufacture of glass

Unlike ordinary glass melting temperatures, it is required to produce a much higher temperature than that of ordinary glass.

Glass paste needs a temperature of about 700 ° C to get liquid. The high temperature in the production of securitized glass increases the mechanical strength of the glass considerably. Semi-secured glass is produced if the cooling operation is not happen wrong

In the process of glass making, selecting the desired dimensions is very necessary. The reason is that any operations such as cutting and drilling will break the glass.

Flute Glass

Fluat glass is a type of glass that is highly resistant.

The diameter of the flute glass produced is from 0.5 to 25 mm.

The width of the glass should not exceed 3 meters. This glass is melted in a furnace at 1600 ° C. And it becomes a pasty. Temperature control inside the furnace reduces the temperature from 1000 to 600 degrees.

This will give the glass the necessary consistency and stiffness.

Manufacture and manufacture of laminated glass

To make the first laminated glass, they apply a layer of PVC ON THE glass then redo this.

The laminate glass is then placed in an autoclave. The bottom of this machine is a complete vacuum.

This allows the air to pass through the glass.

Due to the heat inside the autoclave, the PVB adheres to the glass. This will make the glass stronger and tighter. These factors in the production cause high resistance in the laminated glass. Therefore, laminated glass is a good insulation against sound and temperature.
