    • The present invention discloses a feed water composition for boilers whose main ingredient is a purified ethylene glycol aqueous solution that is a mixture of purified ethylene glycol and pure water in a weight ratio of 70-9 0 : 10-30 wt%. The inventive feed water composition comprises 92.1 to 98.8 wt% of the purified ethylene glycol aqueous solution, 0.1 to 2.0 wt% of sodium benzoate, 0.1 to 1.5 wt% of tolyltriazole, 0.1 to 0.7 wt% of triethanol amin e, 0.5 to 1.5 wt% of sodium nitrate, 0.3 to 1.2 wt% of sodium molybdate, and 0. 1 to 1.0 wt% of potassium hydroxide. The feed water composition of the present invention prevents the formation of corrosion and scales on internal engines and pipes for boilers, thus making its circulation smooth. Its thermal efficiency is particularly high. Also in severely cold weather, it does not freeze even when the power of the boiler is off for energy saving, thus preventing the cracking of the internal engines and pipes for boilers. In addition, it can be used semi-permanently.

    • PURPOSE: A hot press sintering apparatus is provided to prevent the damage of a molding member by including a first molding part and a second molding part and improve the destruction intensity of the molding member. CONSTITUTION: A hot press sintering apparatus includes a chamber, a molding member(20), a pressing member, and a heating member. The molding member is arranged in the chamber and is filled with a raw material. The pressing member presses the raw material in the molding member. The heating member heats the inside of the chamber. The molding member includes a first molding part(22) and a second molding part(24). The second molding part is inserted into the first molding part and forms a molding space part(24a). The purity of the first molding part is lower than the purity of the second molding part.
    • 目的:提供一种热压烧结装置,通过包括第一成型部件和第二成型部件来防止成型部件的损坏,并提高成型部件的破坏强度。 构成:热压烧结装置包括室,模制构件(20),按压构件和加热构件。 模制构件设置在室中并填充有原料。 按压构件将原料压在成型构件中。 加热构件加热室的内部。 模制构件包括第一模制件(22)和第二模制件(24)。 将第二成型部插入第一成型部,形成成型空间部(24a)。 第一成型部件的纯度低于第二成型部件的纯度。
