    • A vertical solid-liquid contact apparatus, comprising: a plurality of stirring chambers disposed vertically adjacent to each other in series, a plurality of partitioning plates each partitioning an adjacent pair of the stirring chambers and provided with a communicating hole for communication between the adjacent pair of the stirring chambers, and a liquid inlet and a solid inlet provided at an upper part and a lower part of the apparatus. Each stirring chamber has an inner side wall defining the stirring chamber, a radially ejecting stirring blade, and at least one baffle fixed on the inner side wall so as to extend vertically. The stirring blade and the baffle are positionally biased to a lower side of the stirring chamber. The apparatus exhibits a good uniformity of solid-liquid flows and a high contact efficiency, is also simple in structure and allows easy scale-up. The apparatus can be widely applied to unit operations in the chemical industry. The apparatus exhibits a particularly good solid-liquid contact efficiency when operated in the neighborhood of its maximum load.
    • 一种垂直固液接触装置,包括:多个彼此垂直相邻设置的搅拌室,多个分隔板,每个隔板分隔相邻的一对搅拌室,并设置有用于在相邻的对之间连通的连通孔 的搅拌室,以及设置在设备的上部和下部的液体入口和固体入口。 每个搅拌室具有限定搅拌室的内侧壁,径向喷射的搅拌叶片和固定在内侧壁上以便垂直延伸的至少一个挡板。 搅拌叶片和挡板位于偏置于搅拌室的下侧。 该装置表现出良好的固液流动均匀性和高接触效率,结构简单,容易放大。 该设备可广泛应用于化工行业的单位业务。 当在其最大负载附近操作时,该装置表现出特别好的固液接触效率。

    • A polyamide resin-based heat-shrinkable multilayer film having excellent heat shrinkability and strength, as well as a high degree of deep A polyamide resin-based heat-shrinkable multilayer film having excellent heat shrinkability and strength, as well as a high degree of deep drawability as represented a shorter side-basis draw ratio (D/L) in excess of 0.6 between a maximum draw depth (D) and a shorter side length (L) of a mold opening is provided. The multilayer film is characterized by including a surface layer (a) comprising a thermoplastic resin, an intermediate layer (b) comprising a polyamide resin, and a surface layer (c) comprising a sealable resin, wherein (A) the intermediate layer (b) comprises a mixture of an aliphatic polyamide having a melting point of at least 180°C, and an amorphous aromatic polyamide comprising a polycondensation product of an aliphatic diamine with is ophthalmic acid and terephthalic acid as main acid components, including 25-45 wt.% of the amorphous aromatic polyamide, and has a thickness exceeding 25% and at most 50 % of a total thickness of whole layers, and exhibiting: (B) tensile stresses at an elongation of 100% as measured in a tensile test at 100°C, including 3 - 22 N in at least one of a longitudinal direction (MD) and a transverse direction (TD) and an average of MD and TD values of 3-20N, and (C) a shrinkage in hot water at 90°C of 3 to 20% in each of MD and TD. The film is produced through a process of strictly controlling biaxial stretching ratios and heat-relaxation ratios.
