    • PROBLEM TO BE SOLVED: To provide a method to prevent the formation of gaseous inclusions in glass sheets.SOLUTION: There are provided a system and method for controlling the environment (e.g. oxygen, hydrogen, humidity, temperature, gas flow rate, pressure) around one or more vessels in a glass manufacturing system. In the preferred embodiment, the system includes a closed-loop control system and a capsule that are used to control the level of hydrogen around the exterior (non glass contact surface) of the vessel(s) so as to suppress the formation of gaseous inclusions and surface blisters in glass sheets. In addition, the closed-loop control system and capsule can be used to help cool molten glass while the molten glass travels from one vessel to another vessel in the glass manufacturing system. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel(s) so as to reduce the oxidation of precious metals on the vessel(s).
    • 要解决的问题:提供一种防止在玻璃板中形成气态夹杂物的方法。 解决方案:提供了一种用于控制玻璃制造系统中的一个或多个容器周围的环境(例如氧气,氢气,湿度,温度,气体流速,压力)的系统和方法。 在优选实施例中,系统包括闭环控制系统和胶囊,其用于控制​​在容器的外部(非玻璃接触表面)周围的氢的水平,以便抑制气体夹杂物的形成 并在玻璃板表面起泡。 此外,闭路控制系统和胶囊可用于帮助冷却熔融玻璃,同时熔融玻璃在玻璃制造系统中从一个容器移动到另一个容器。 此外,闭环控制系统和胶囊可用于维持容器周围具有最小氧气的气氛,以便减少容器上的贵金属的氧化。 版权所有(C)2013,JPO&INPIT

    • PURPOSE: To absorb remaining bubbles in a material effectively while shortening a cooling time extremely, by annealing molten glass approximately at a temperature where the average temperature of the molten glass is a temperature to show the highest absorption rate of bubbles, and quenching it in a temperature range except it.
      CONSTITUTION: The resolving tank 12 is provided with the feed opening 13 for raw material, the heat storage chambers 14 are set at both the sides of the resolving tank 12, and they are connected to the nozzles 15.... Flame obtained by burning a heavy oil is produced from the nozzles 15..., raw materials are melted, and a glass material is accumulated in the resolving tank 12. The raw materials receive heat at least at 1,500°C for ≥30min, and the raw materials at about 1,500W1,550°C flow into the cooling tank 17. In the sections 17a, 17b, and 17c, the sections 17a and 17c are forcedly cooling sections, and the section 17b is a naturally cooling section. Consequently, molten glass is quenched in the sections 17a and 17c, and annealed in the section 17b.
