8mm Thick, Pioneer Float Glass Processing Treatment Equipment
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.
The production technology of float glass is the largest scale mechanization and automation methods of production of flat glass production technology at present time.
The float glass has a flatness surface, excellent optical performance, no distortions, due to its good quality, the yield float glass can be used for deep processing fabrication.
2. Characteristic
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.

6. Main Equipment Description
6.1 Batch Plant
For batching and mixing the raw materials.
6.2 Furance
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
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.
Besides the good melting efficient, the bright and clean surface of metallic tin is also another important key to produce good float glass product, So, an inert gas or reducing gas to be adopted for a kind of protection gas to prevent the tin from oxidized.
Nitrogen gas, a kind of colorless and odorless gas, which is a main component of protection gas, with a dissociation states in nature. An inert gas as nitrogen gas, it can not combust in air nor dissolve in water, which can prevent the oxidization of metallic tin, and no reaction between nitrogen gas and metallic tin.
Hydrogen gas is a lightest, colorless and odorless combustion gas, mainly existing under compound state. It is a strong reducing agent, with min viscosity, high conductivity and strong chemical activity, which can have chemical reaction with many materials to produce various kinds of hydride.
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.
