The Effect of Foam in Surface Molten Glass and Use of TNBT for the Combustion Process in Furnace to Temperature and Produced Glass Quality

摘要

In the process of making glass with the Float Process can be divided into several stages of the production process such as preparation of raw materials, mixing, melting, forming, cutting, and packing. From this process that becomes a benchmark of glass quality is the type and number of defects in the glass caused by the processes that occur in making glass. The glass defect can be from the existing production process stage. In the smelting process occurs in the furnace area, where in the combustion process, the fusion that occurs there is foam that can interfere with the combustion process in the furnace. This can occur due to foam can prevent the entry of radiant heat into the liquid glass. So that with the foam that is formed will be analyzed what effects and variables can occur and the application of tetra n-butyl titanate to the foam formed. With the use of TNBT can eliminate the foam that occurs and can directly reduce the temperature of the crown furnace that results in a decrease in glass defects that occur and increase production efficiency.
