1. Brief Description
The name of float glass is because of the glass liquid floating and forming on a metallic tin liquid surface. By using this forming method, it is not need to overcome the gravity of the glass, it can enlarge the width of the glass, improve the speed of stretch, and increase the capacity and scale of production.
In 1965, China started to research and develop its own float glass technology and successfully put into production and exported the float glass products and technology to the world.
Nowadays, the international glass new technology is developing in the fields of energy, materials, environmental protection, information, biology. Developing new technology by changing the external and internal performance of glass product, it allows the glass product having excellent function of strength, energy saving, thermal insulation, fire resistance, sunlight protective......etc.
Because the glass liquid forms on the metallic tin liquid surface, it could achieve a high grade double faced fired polishing glass surface. The parallelism and flatness of float glass are as better as mechanical polishing effect, but it has a better mechanical capacity and chemical stability than mechanical polishing glass.
3. Scope of Supply
4. Raw Materials
Main materials are mainly including:
5. Technical Flow Chart of Float Glass Line
6. Main Equipment Description
6.1 Batch Plant
For batching and mixing the raw materials.
The melting tank is key part of glass production line, the refractory materials quality is very important.
6.3 Tin Bath
It is a key and one of most important equipment of float glass production line.
6.4.Protection Gas Station
Tin is easy to reaction with oxygen, sulfur under high temperature and form an oxide, its oxide (SnO2, SnO) will seriously pollute the glass liquid, this will affect the quality of the glass.
In order to overcome the air and oxygen brought through the entering of the glass liquid and inert gas itself, a center percentage of hydrogen gas shall be added into nitrogen gas.
Basic Physical and Chemical Characters of Nitrogen and Hydrogen Gas:
|Density under standard state||1.251 kg/m3|
|Boiling Point||-195.8 °C|
|Specific Heat Capacity||Cp||1.047 kJ/kg·°C|
|Thermal Conductivity||0.233 W/m·k|
|Density under standard state||0.090 kg/m3|
|Boiling Point||-252.2 °C|
|Specific Heat Capacity||Cp||12.269 kJ/kg·°C|
|Thermal Conductivity||9.469 W/m·k|
6.5. Annealing Lehr
In glass technology, annealing means to put the glass into the annealing lehr for a certain time or reduce the temperature with a slow speed, so as to no additional permanent stress or temporary stress will produce. Namely, annealing also means a process which will reduce or eliminate the thermal stress of glass.
When the heat treatment of glass is under taking between normal temperature and softening temperature, the structure and property of glass will change obviously, such as stress, phase splitting, devitrification, etc.
