德恩數(shù)控：玻璃浮法成型的原理

浮法玻璃的成型原理：是讓處于高溫熔融狀態(tài)的玻璃液浮在相對(duì)密度大的金屬液表面上，受表面張力作用是玻璃具有光潔平整的表面，并在其后的冷卻硬化過(guò)程中加以保持，則能生產(chǎn)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.

介質(zhì)的選擇：

Media choice:

1、在1050℃溫度下的密度大于玻璃。

1, at a temperature of 1050 degrees Celsius is greater than the density of glass.

2、金屬的熔點(diǎn)低于600℃，沸點(diǎn)高于1050℃，1000℃左右的蒸氣壓應(yīng)盡可能低。

2, 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℃左右溫度下，不與玻璃發(fā)生化學(xué)反應(yīng)。

3, at the temperature of 1000 degrees Celsius, not with the chemical reaction of the glass.

由于表面張力的增厚作用，即使短期被拉薄，隨后會(huì)在表面張力的作用下，縮小寬度，厚度回到平衡厚度。只有當(dāng)玻璃的溫度下降到使玻璃的粘度迅速增大，而表面張力則增加不多，巨大地粘滯力使表面張力難以發(fā)揮作用，因此，當(dāng)有拉邊器是，在強(qiáng)大的拉力下就可使玻璃變薄。

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.
