浮法玻璃的成型原理：是让处于高温熔融状态的玻璃液浮在相对密度大的金属液表面上，受表面张力作用是玻璃具有光洁平整的表面，并在其后的冷却硬化过程中加以保持，则能生产浮法玻璃。

The forming principle of float glass: glass is let liquid floating in high temperature molten state in the molten metal surface relative density on the surface of the glass is influenced by the surface tension effect is smooth, and to maintain the cooling hardening process followed, can float glass production.

介质的选择：

Media choice:

1、在1050℃温度下的密度大于玻璃at a temperature of 1050 degrees Celsius is greater than the density of glass.

2、金属的熔点于600℃，沸点高于1050℃，1000℃左右的蒸气压应尽可能the melting point of the metal below 600 degrees Celsius, boiling point higher than 1050 degrees Celsius, 1000 degrees Celsius vapor pressure should be as low as possible.

3、在1000℃左右温度下，不与玻璃发生化学反应。at the temperature of 1000 degrees Celsius, not with the chemical reaction of the glass.

由于表面张力的增厚作用，即使短期被拉薄，随后会在表面张力的作用下，缩小宽度，厚度回到平衡厚度。只有当玻璃的温度下降到使玻璃的粘度迅速增大，而表面张力则增加，巨大地粘滞力使表面张力难以发挥作用，因此，当有拉边器是，在强大的拉力下可使玻璃变薄。

Due to the thickening of the surface tension, even if the short term is thin, and then will be in the role of surface tension, reduce the width, thickness back to the balance of thickness. Only when the glass temperature dropped to the glass viscosity increases rapidly, while the surface tension increase, huge viscous force of surface tension is difficult to play a role, therefore, when the edge roller is in strong tension can make the glass thinning.
