Glass (glass) is a material used to decorate the interior of the building for beauty and to add brightness to the house, used in the automotive industry and has a wide range of uses. About 80% of the raw materials used in the manufacture of glass are derived from source of production Domestic such as silica sand, quarry stone, dolomite, cutlets and raw materials imported from abroad such as soda ash, carbon powder, iron powder, sodium sulfate.
The glass manufacturing process will begin by mixing the raw materials such as glass sand, quarry stone, dolomite stone, shards of glass, soda ash, limestone and sodium sulfate in the specified ratio. Then put the resulting mixture into the oven. With a temperature of 1,500 degrees Celsius until various materials are melted until the glass water is obtained fuels include After that, the temperature of the glass water is adjusted to about 1,100 degrees Celsius until it becomes viscous enough for the glass water to be formed. It is a glass sheet on a fine surface, telling the sharpness of this process to get a sheet of glass called float glass. It has better properties than glass sheets produced by other systems. The surface of the glass sheet is smooth, not wavy, has a uniform thickness throughout. Sheet with bright, shiny surface, not cloudy. The production of sheet glass can be divided into 2 steps:
1. Sheet glass industry
2. Continuous glass industry
The sheet glass industry is the basic glass manufacturing industry. Can be divided into two main types:
1. float glass
2. Sheet glass
The industry continues to fall
The continuous glass industry is the processing of float glass and sheet glass. For the benefit of use according to the different properties and types of work, including
