    • The present invention relates to a method for continuous preparation of a hydrous zirconia sol dispersed by nanometer-sized spherical hydrous zirconia particles having an average diameter(dp) of 1˜250 nm, which method comprises supplying the aqueous solution of a zirconium salt at a concentration of 0.001-0.2 mole/l to a reactor consisting of one or more than two reaction tubes, and then irradiating microwave to the stream of the said aqueous solution in the reactor so that the said solution may be heated in a flow state. Contrary to the method employing a conventional batch-type reactor or semi-continuous stirred-type reactor, the method for continuous preparation of a hydrous zirconia sol according to the present invention can allow various operational parameters to be controlled in a certain range and thus contributes to remarkably improve the quality of a hydrous zirconia sol to be prepared or of the zirconia powder obtainable as a final product.
    • 本发明涉及一种用于连续制备由具有1〜250nm平均直径(nm)的纳米尺寸球状水合氧化锆颗粒分散的含水氧化锆溶胶的方法,该方法包括: 浓度为0.001-0.2摩尔/升的锆盐水溶液加到由一个或多于两个反应管组成的反应器中,然后将微波照射到反应器中的所述水溶液流中,使得所述溶液可以 在流动状态下被加热。 与使用常规间歇式反应器或半连续搅拌式反应器的方法相反,根据本发明的连续制备含水氧化锆溶胶的方法可以使各种操作参数被控制在一定范围内,因此有助于 显着提高待制备的含水氧化锆溶胶的质量或作为最终产物获得的氧化锆粉末的质量。

    • An air conditioner including a cabinet, a partition plate provided in the cabinet to partition an internal space of the cabinet, and an air inlet port and an air outlet port provided on the cabinet to draw and discharge indoor air into and from the cabinet, respectively. The air conditioner further has an evaporator placed adjacent to the air inlet port, a fan to draw the indoor air into the cabinet through the air inlet port, an air guide duct to guide the indoor, and an air discharging duct supported on the partition plate adjacent to the air guide duct. Because the air discharging duct is supported on the partition plate, the air conditioner prevents the air discharging duct from being displaced from a desired position regardless of a vibration or impact applied to the air discharging duct. Thus, the assembling process of the air conditioner is simplified.
    • 一种空调机,包括机柜,设置在机柜中以分隔机柜内部空间的隔板,以及设置在机柜上的进气口和出气口,以分别将室内空气抽入和排出柜体 。 空气调节器还具有邻近进气口设置的蒸发器,通过进气口将室内空气吸入机壳的风扇,引导室内的导气管,以及支撑在隔板上的排气管 邻近导气管。 由于空气排放管被支撑在隔板上,所以空气调节器防止排气管从所需位置移动,而不管施加到排气管的振动或冲击如何。 因此,简化了空调的组装过程。
